China accounted for 95% of the world’s new coal power construction activity in 2023, according to the latest annual report from Global Energy Monitor (GEM).
Construction began on 70 gigawatts (GW) of new capacity in China, up four-fold since 2019, says GEM’s annual report on the global coal power industry.
This compares with less than 4GW of new coal power construction starting in the rest of the world – the lowest since 2014.
Outside China, only 32 countries have new coal projects at pre-construction phases of development and just seven have plants under construction.
While global coal power capacity – both overall and outside China – grew in 2023, GEM says this is likely to be a “blip” that will be offset by accelerating coal retirements in the next few years in the US and Europe.
Other key findings of the report include that construction of coal-fired power plants globally – excluding China – declined for the second year in a row. However, coal power plant retirements were also at the lowest level since 2011.
‘Pivotal juncture’ for China
In China, 47.4GW of coal power capacity came online in 2023, GEM says. This increase accounted for two-thirds of the global rise in operating coal power capacity, which climbed 2% to 2,130GW.
China’s 70.2GW of new construction getting underway in 2023 represents 19-times more than the rest of the world’s 3.7GW. As the figure below highlights, the country’s trajectory (red line) is diverging significantly from the rest of the world (orange line).
The level of new construction starting in China is nearly quadruple what it was in 2019, when the country hit a nine-year annual low of entirely new coal power stations starting.
This is the fourth year in a row that the amount of new coal construction starting has increased in China. This is out of line with President Xi Jinping’s 2021 pledge to “strictly control” new coal power capacity, GEM states.
In early 2022, China’s National Energy Administration’s 14th five‐year plan for a “modern energy system” stated that 30GW of coal power would be retired by 2025.
However, when counting larger coal units with capacity of at least 30 megawatts, less than 9GW of power plants have been shut down in the last three years, and few others have plans to retire, GEM notes.
If China is to meet this 30GW retirement target, it “needs to take immediate action”, GEM adds.
In a statement, Qi Qin, China analyst at the Centre for Research on Energy and Clean Air, said:
“The recent surge in coal power development in China starkly contrasts with the global trend, putting China’s 2025 climate targets at risk. At this pivotal juncture, it is crucial for China to impose stricter controls on coal power projects and expedite the transition towards renewable energy to realign with its climate commitments.”
Collectively, China, India, Bangladesh, Zimbabwe, Indonesia, Kazakhstan, Laos, Turkey, Russia, Pakistan and Vietnam account for 95% of global pre-construction capacity, according to the GEM report.
The 5% remaining is distributed among 21 countries, the tracker finds. Of these, 11 have one project and are on the brink of achieving the “no new coal” milestone, it adds.
The tracker identifies 20.9GW of entirely new coal power proposals outside of China in 2023. This was led by India, which saw 11.4GW of new coal capacity proposed, more than any year since 2016. This was in part due to the revival of several stalled projects in the country, GEM explains.
Kazakhstan also saw 4.6GW of new proposals and Indonesia saw 2.5GW. Some 4.1GW of previously shelved or cancelled capacity is now considered “proposed” again.
Another handful of countries – Russia, the Philippines, Botswana and Nigeria – also saw revived proposals and construction restarting in 2023.
Retirements slow
Globally, a total of 69.5GW of coal power came online in 2023, while 21.1GW was retired, GEM finds. This led to the highest net increase in global operating coal capacity since 2016, with a 48.4GW jump.
New capacity also came online in Indonesia (5.9GW), India (5.5GW), Vietnam (2.6GW), Japan (2.5GW), Bangladesh (1.9GW), Pakistan (1.7GW), South Korea (1GW), Greece (0.7GW) and Zimbabwe (0.3GW).
In total during 2023, the tracker found 22.1GW came online and 17.4GW was retired outside of China. This resulted in a 4.7GW net increase in the world’s coal fleet operating outside China. Globally, coal power capacity reached 2,130GW in 2023, up from 2% a year earlier.
The US contributed nearly half of coal power retirements, GEM says, with 9.7GW shuttering in 2023. However, this is a drop in retirements from 14.7GW in 2022, and a peak of 21.7GW in 2015.
Elsewhere, the EU and UK represented nearly a quarter of retirements, with 3.1GW closing in the UK, 0.6GW in Italy and 0.5GW in Poland. There is now just one operating coal-fired power plant in the UK, with the Ratcliffe-on-Soar set to close in September 2024.
Overall, global coal power plant retirements were at their lowest level since 2011, as the figure below shows.
Outside of China, the number of coal-fired power plants starting construction declined for the second consecutive year, hitting its lowest level since data collection began in 2015, GEM notes.
Less than 4GW of new projects began construction outside of China in 2023, far below the average of 16GW between 2015 and 2022. Just seven countries started construction, with one plant each in India, Laos, Nigeria, Pakistan and Russia, as well as three plants in Indonesia.
Construction has not started on any coal plants in Latin America since 2016, and none has started in Organisation for Economic Co-operation and Development (OECD), European or Middle Eastern countries since 2019, GEM says.
Nigeria’s Ugboba power station, located at the mine-mouth of the Idowu Falola Coal Mines in the Aniocha North local government area of Delta state, is the first known construction of a coal power plant in Africa since 2019, the report says.
The G7 – which accounts for 15% (310GW) of the world’s operating coal capacity, down from 32% (443GW) in 2015 – has no new coal capacity under construction. However, there is still one proposed coal power plant in Japan and two in the US.
Both of the proposed sites in the US, the 0.4GW CONSOL Project in Pennsylvania and the newly announced 0.4GW Susitna power station in Alaska, are expected to use carbon capture and storage technologies (CCS).
GEM says that these technologies are “effectively uncertain and expensive distractions from the urgent need to phase out coal”.
The G20 is home to 92% of the world’s operating coal capacity (1,968GW) and 88% of pre-construction coal capacity (336GW). Brazil, the current G20 chair, saw its pipeline of pre-construction capacity fall in 2023, but still has two prospective projects remaining – the last pre-construction coal power plants in Latin America.
No new coal nations
Overall, coal capacity reached an all time high in 2023, GEM’s tracker says.
Operating coal capacity outside China grew for the first time since 2019, as less coal capacity retired than in any other single year in more than a decade, as the figure below shows.
The world’s operating coal power capacity is up 11% since 2015, when governments agreed to keep the global average temperature to well below 2C above pre-industrial levels and aim to limit warming to 1.5C under the Paris Agreement.
Outside of China, there are still 113GW of coal power projects under construction. While this is only slightly up from the previous year’s level of 110GW, it still highlights that the coal sector is not in line with the International Energy Agency’s (IEA) 1.5C scenario, GEM says.
Across all IEA scenarios that meet international climate goals there is a rapid decline in global coal emissions.
Globally, pre-construction capacity rose 6% in 2023, “crystallising the importance of calls to stop proposing and breaking ground on new coal plants”, GEM’s report says.
Only 15% (317GW) of currently operating coal power capacity has a commitment to retire in line with Paris Agreement goals, it adds.
Phasing out unabated coal generation by 2040 – in line with the IEA’s 1.5C pathway – would require an average of 126GW of retirements every year for the next 17 years, GEM notes. This is the equivalent of two coal power plants per week.
Even steeper cuts would be needed to account for the 578GW of coal power plants also under construction and in pre-construction phases of development, GEM says.
There were 12 new countries that committed to developing no new coal generation in 2023, by joining the Powering Past Coal Alliance. This brings the total number of countries up to 101 that have either formally declared they will have no new coal or have abandoned any coal plans they have had over the last decade, GEM notes.
Since 2015, there has been a 68% reduction in global pre-construction capacity, GEM found. New construction starts are now at their lowest level outside of China, since data collection began.
GEM’s report suggests that coal power projects that utilise CCS and those used to power industrial activities may be “a last frontier” for new coal proposals.
For example, Zimbabwe’s 1.9GW of new coal capacity proposed in 2023 is made up of two projects, the Prestige power station and the Gweru power station, designed to power smelters for extracting chromium from ore.
Zimbabwe is one of one six countries, beyond China and India, to have increased its total planned capacity over the past year, along with Kazakhstan, Kyrgyzstan, Russia, Zimbabwe, the US and the Philippines.
At COP28, 130 countries signalled their intent to phase out unabated coal power and stop investing in new unabated coal-fired power plants within this decade, by signing the Global Renewables and Energy Efficiency Pledge.
In addition, the final global stocktake agreement at COP28 reiterated the pledge from COP26 to phase down unabated coal power, but still does not define what “unabated” means. Additionally, wording from earlier drafts on ending permitting of new coal power was omitted in the final text.
“Coal power is at the edge of a precipice, facing political and civil opposition and increasingly uncompetitive economics,” GEM’s report states.
In a statement, Flora Champenois, coal programme director for GEM said:
“Coal’s fortunes this year are an anomaly, as all signs point to reversing course from this accelerated expansion. But countries that have coal plants to retire need to do so more quickly, and countries that have plans for new coal plants must make sure these are never built. Otherwise we can forget about meeting our goals in the Paris Agreement and reaping the benefits that a swift transition to clean energy will bring.”

Key developments
Food inflation on the rise
DELUGE STRIKES FOOD: Extreme rainfall and flooding across the Mediterranean and north Africa has “battered the winter growing regions that feed Europe…threatening food price rises”, reported the Financial Times. Western France has “endured more than 36 days of continuous rain”, while farmers’ associations in Spain’s Andalusia estimate that “20% of all production has been lost”, it added. Policy expert David Barmes told the paper that the “latest storms were part of a wider pattern of climate shocks feeding into food price inflation”.

NO BEEF: The UK’s beef farmers, meanwhile, “face a double blow” from climate change as “relentless rain forces them to keep cows indoors”, while last summer’s drought hit hay supplies, said another Financial Times article. At the same time, indoor growers in south England described a 60% increase in electricity standing charges as a “ticking timebomb” that could “force them to raise their prices or stop production, which will further fuel food price inflation”, wrote the Guardian.
‘TINDERBOX’ AND TARIFFS: A study, covered by the Guardian, warned that major extreme weather and other “shocks” could “spark social unrest and even food riots in the UK”. Experts cited “chronic” vulnerabilities, including climate change, low incomes, poor farming policy and “fragile” supply chains that have made the UK’s food system a “tinderbox”. A New York Times explainer noted that while trade could once guard against food supply shocks, barriers such as tariffs and export controls – which are being “increasingly” used by politicians – “can shut off that safety valve”.
El Niño looms
NEW ENSO INDEX: Researchers have developed a new index for calculating El Niño, the large-scale climate pattern that influences global weather and causes “billions in damages by bringing floods to some regions and drought to others”, reported CNN. It added that climate change is making it more difficult for scientists to observe El Niño patterns by warming up the entire ocean. The outlet said that with the new metric, “scientists can now see it earlier and our long-range weather forecasts will be improved for it.”
WARMING WARNING: Meanwhile, the US Climate Prediction Center announced that there is a 60% chance of the current La Niña conditions shifting towards a neutral state over the next few months, with an El Niño likely to follow in late spring, according to Reuters. The Vibes, a Malaysian news outlet, quoted a climate scientist saying: “If the El Niño does materialise, it could possibly push 2026 or 2027 as the warmest year on record, replacing 2024.”
CROP IMPACTS: Reuters noted that neutral conditions lead to “more stable weather and potentially better crop yields”. However, the newswire added, an El Niño state would mean “worsening drought conditions and issues for the next growing season” to Australia. El Niño also “typically brings a poor south-west monsoon to India, including droughts”, reported the Hindu’s Business Line. A 2024 guest post for Carbon Brief explained that El Niño is linked to crop failure in south-eastern Africa and south-east Asia.
News and views
- DAM-AG-ES: Several South Korean farmers filed a lawsuit against the country’s state-owned utility company, “seek[ing] financial compensation for climate-related agricultural damages”, reported United Press International. Meanwhile, a national climate change assessment for the Philippines found that the country “lost up to $219bn in agricultural damages from typhoons, floods and droughts” over 2000-10, according to Eco-Business.
- SCORCHED GRASS: South Africa’s Western Cape province is experiencing “one of the worst droughts in living memory”, which is “scorching grass and killing livestock”, said Reuters. The newswire wrote: “In 2015, a drought almost dried up the taps in the city; farmers say this one has been even more brutal than a decade ago.”
- NOUVELLE VEG: New guidelines published under France’s national food, nutrition and climate strategy “urged” citizens to “limit” their meat consumption, reported Euronews. The delayed strategy comes a month after the US government “upended decades of recommendations by touting consumption of red meat and full-fat dairy”, it noted.
- COURTING DISASTER: India’s top green court accepted the findings of a committee that “found no flaws” in greenlighting the Great Nicobar project that “will lead to the felling of a million trees” and translocating corals, reported Mongabay. The court found “no good ground to interfere”, despite “threats to a globally unique biodiversity hotspot” and Indigenous tribes at risk of displacement by the project, wrote Frontline.
- FISH FALLING: A new study found that fish biomass is “falling by 7.2% from as little as 0.1C of warming per decade”, noted the Guardian. While experts also pointed to the role of overfishing in marine life loss, marine ecologist and study lead author Dr Shahar Chaikin told the outlet: “Our research proves exactly what that biological cost [of warming] looks like underwater.”
- TOO HOT FOR COFFEE: According to new analysis by Climate Central, countries where coffee beans are grown “are becoming too hot to cultivate them”, reported the Guardian. The world’s top five coffee-growing countries faced “57 additional days of coffee-harming heat” annually because of climate change, it added.
Spotlight
Nature talks inch forward
This week, Carbon Brief covers the latest round of negotiations under the UN Convention on Biological Diversity (CBD), which occurred in Rome over 16-19 February.
The penultimate set of biodiversity negotiations before October’s Conference of the Parties ended in Rome last week, leaving plenty of unfinished business.
The CBD’s subsidiary body on implementation (SBI) met in the Italian capital for four days to discuss a range of issues, including biodiversity finance and reviewing progress towards the nature targets agreed under the Kunming-Montreal Global Biodiversity Framework (GBF).
However, many of the major sticking points – particularly around finance – will have to wait until later this summer, leaving some observers worried about the capacity for delegates to get through a packed agenda at COP17.
The SBI, along with the subsidiary body on scientific, technical and technological advice (SBSTTA) will both meet in Nairobi, Kenya, later this summer for a final round of talks before COP17 kicks off in Yerevan, Armenia, on 19 October.
Money talks
Finance for nature has long been a sticking point at negotiations under the CBD.
Discussions on a new fund for biodiversity derailed biodiversity talks in Cali, Colombia, in autumn 2024, requiring resumed talks a few months later.
Despite this, finance was barely on the agenda at the SBI meetings in Rome. Delegates discussed three studies on the relationship between debt sustainability and implementation of nature plans, but the more substantive talks are set to take place at the next SBI meeting in Nairobi.
Several parties “highlighted concerns with the imbalance of work” on finance between these SBI talks and the next ones, reported Earth Negotiations Bulletin (ENB).
Lim Li Ching, senior researcher at Third World Network, noted that tensions around finance permeated every aspect of the talks. She told Carbon Brief:
“If you’re talking about the gender plan of action – if there’s little or no financial resources provided to actually put it into practice and implement it, then it’s [just] paper, right? Same with the reporting requirements and obligations.”
Monitoring and reporting
Closely linked to the issue of finance is the obligations of parties to report on their progress towards the goals and targets of the GBF.
Parties do so through the submission of national reports.
Several parties at the talks pointed to a lack of timely funding for driving delays in their reporting, according to ENB.
A note released by the CBD Secretariat in December said that no parties had submitted their national reports yet; by the time of the SBI meetings, only the EU had. It further noted that just 58 parties had submitted their national biodiversity plans, which were initially meant to be published by COP16, in October 2024.
Linda Krueger, director of biodiversity and infrastructure policy at the environmental not-for-profit Nature Conservancy, told Carbon Brief that despite the sparse submissions, parties are “very focused on the national report preparation”. She added:
“Everybody wants to be able to show that we’re on the path and that there still is a pathway to getting to 2030 that’s positive and largely in the right direction.”
Watch, read, listen
NET LOSS: Nigeria’s marine life is being “threatened” by “ghost gear” – nets and other fishing equipment discarded in the ocean – said Dialogue Earth.
COMEBACK CAUSALITY: A Vox long-read looked at whether Costa Rica’s “payments for ecosystem services” programme helped the country turn a corner on deforestation.
HOMEGROWN GOALS: A Straits Times podcast discussed whether import-dependent Singapore can afford to shelve its goal to produce 30% of its food locally by 2030.
‘RUSTING’ RIVERS: The Financial Times took a closer look at a “strange new force blighting the [Arctic] landscape”: rivers turning rust-orange due to global warming.

Cropped 25 February 2026: Food inflation strikes | El Niño looms | Biodiversity talks stagnate
For millions of consumers, the sustainability scheme stickers found on everything from bananas to chocolate bars and wooden furniture are a way to choose products that are greener and more ethical than some of the alternatives.
Inga Petersen, executive director of the Global Battery Alliance (GBA), is on a mission to create a similar scheme for one of the building blocks of the transition from fossil fuels to clean energy systems: batteries.
“Right now, it’s a race to the bottom for whoever makes the cheapest battery,” Petersen told Climate Home News in an interview.
The GBA is working with industry, international organisations, NGOs and governments to establish a sustainable and transparent battery value chain by 2030.
“One of the things we’re trying to do is to create a marketplace where products can compete on elements other than price,” Petersen said.
Under the GBA’s plan, digital product passports and traceability would be used to issue product-level sustainability certifications, similar to those commonplace in other sectors such as forestry, Petersen said.
Managing battery boom’s risks
Over the past decade, battery deployment has increased 20-fold, driven by record-breaking electric vehicle (EV) sales and a booming market for batteries to store intermittent renewable energy.
Falling prices have been instrumental to the rapid expansion of the battery market. But the breakneck pace of growth has exposed the potential environmental and social harms associated with unregulated battery production.
From South America to Zimbabwe and Indonesia, mineral extraction and refining has led to social conflict, environmental damage, human rights violations and deforestation. In Indonesia, the nickel industry is powered by coal while in Europe, production plants have been met with strong local opposition over pollution concerns.
“We cannot manage these risks if we don’t have transparency,” Petersen said.

West Africa’s first lithium mine awaits go-ahead as Ghana seeks better deal
Ghana wants to benefit from the scramble for lithium but its reliance on mining firms for revenue and expertise weakens its ability to negotiate preferential terms, experts say
The GBA was established in 2017 in response to concerns about the battery industry’s impact as demand was forecast to boom and reports of child labour in the cobalt mines of the Democratic Republic of the Congo made headlines.
The alliance’s initial 19 members recognised that the industry needed to scale rapidly but with “social, environmental and governance guardrails”, said Petersen, who previously worked with the UN Environment Programme to develop guiding principles to minimise the environmental impact of mining.
Digital battery passport
Today, the alliance is working to develop a global certification scheme that will recognise batteries that meet minimum thresholds across a set of environmental, social and governance benchmarks it has defined along the entire value chain.
Participating mines, manufacturing plants and recycling facilities will have to provide data for their greenhouse gas emissions as well as how they perform against benchmarks for assessing biodiversity loss, pollution, child and forced labour, community impacts and respect for the rights of Indigenous peoples, for example.
The data will be independently verified, scored, aggregated and recorded on a battery passport – a digital record of the battery’s composition, which will include the origin of its raw materials and its performance against the GBA’s sustainability benchmarks.
The scheme is due to launch in 2027.
A carrot and a stick
Since the start of the year, some of the world’s largest battery companies have been voluntarily participating in the biggest pilot of the scheme to date.
More than 30 companies across the EV battery and stationary storage supply chains are involved, among them Chinese battery giants CATL and BYD subsidiary FinDreams Battery, miner Rio Tinto, battery producers Samsung SDI and Siemens, automotive supplier Denso and Tesla.
Petersen said she was “thrilled” about support for the scheme. Amid a growing pushback against sustainability rules and standards, “these companies are stepping up to send a public signal that they are still committed to a sustainable and responsible battery value chain,” she said.
There are other motivations for battery producers to know where components in their batteries have come from and whether they have been produced responsibly.
In 2023, the EU adopted a law regulating the batteries sold on its market.
From 2027, it mandates all batteries to meet environmental and safety criteria and to have a digital passport accessed via a QR code that contains information about the battery’s composition, its carbon footprint and its recycling content.
The GBA certification is not intended as a compliance instrument for the EU law but it will “add a carrot” by recognising manufacturers that go beyond meeting the bloc’s rules on nature and human rights, Petersen said.
Raising standards in complex supply chain
But challenges remain, in part due to the complexity of battery supply chains.
In the case of timber, “you have a single input material but then you have a very complex range of end products. For batteries, it’s almost the reverse,” Petersen said.
The GBA wants its certification scheme to cover all critical minerals present in batteries, covering dozens of different mining, processing and manufacturing processes and hundreds of facilities.
“One of the biggest impacts will be rewarding the leading performers through preferential access to capital, for example, with investors choosing companies that are managing their risk responsibly and transparently,” Petersen said.

It could help influence public procurement and how companies, such as EV makers, choose their suppliers, she added. End consumers will also be able to access a summary of the GBA’s scores when deciding which product to buy.
US, Europe rush to build battery supply chain
Today, the GBA has more than 150 members across the battery value chain, including more than 50 companies, of which over a dozen are Chinese firms.
China produces over three-quarters of batteries sold globally and it dominates the world’s battery recycling capacity, leaving the US and Europe scrambling to reduce their dependence on Beijing by building their own battery supply chains.
Petersen hopes the alliance’s work can help build trust in the sector amid heightened geopolitical tensions. “People want to know where the materials are coming from and which actors are involved,” she said.
At the same time, companies increasingly recognise that failing to manage sustainability risks can threaten their operations. Protests over environmental concerns have shut down mines and battery factories across the world.
“Most companies know that and that’s why they’re making these efforts,” Petersen added.

Reheating plastic food containers: what science says about microplastics and chemicals in ready meals
How often do you eat takeaway food? What about pre-prepared ready meals? Or maybe just microwaving some leftovers you had in the fridge? In any of these cases, there’s a pretty good chance the container was made out of plastic. Considering that they can be an extremely affordable option, are there any potential downsides we need to be aware of? We decided to investigate.
Scientific research increasingly shows that heating food in plastic packaging can release microplastics and plastic chemicals into the food we eat. A new Greenpeace International review of peer-reviewed studies finds that microwaving plastic food containers significantly increases this release, raising concerns about long-term human health impacts. This article summarises what the science says, what remains uncertain, and what needs to change.
There’s no shortage of research showing how microplastics and nanoplastics have made their way throughout the environment, from snowy mountaintops and Arctic ice, into the beetles, slugs, snails and earthworms at the bottom of the food chain. It’s a similar story with humans, with microplastics found in blood, placenta, lungs, liver and plenty of other places. On top of this, there’s some 16,000 chemicals known to be either present or used in plastic, with a bit over a quarter of those chemicals already identified as being of concern. And there are already just under 1,400 chemicals that have been found in people.
Not just food packaging, but plenty of household items either contain or are made from plastic, meaning they potentially could be a source of exposure as well. So if microplastics and chemicals are everywhere (including inside us), how are they getting there? Should we be concerned that a lot of our food is packaged in plastic?
Greenpeace analysis of 24 articles in peer-reviewed scientific journals found that the plastics we use to package our food are directly risking our health.
Heating food in plastic packaging dramatically increases the levels of microplastics and chemicals that leach into our food.
Plastic food packaging: the good, the bad, and the ugly
The growing trend towards ready meals, online shopping and restaurant delivery, and away from home-prepared meals and individual grocery shopping, is happening in every region of the world. Since the first microwaveable TV dinners were introduced in the US in the 1950s to sell off excess stock of turkey meat after Thanksgiving holidays, pre-packaged ready meals have grown hugely in sales. The global market is worth $190bn in 2025, and is expected to reach a total volume of 71.5 million tonnes by 2030. It’s also predicted that the top five global markets for convenience food (China, USA, Japan, Mexico and Russia) will remain relatively unchanged up to 2030, with the most revenue in 2019 generated by the North America region.
A new report from Greenpeace International set out to analyse articles in peer-reviewed, scientific journals to look at what exactly the research has to say about plastic food packaging and food contact plastics.
Here’s what we found.
Our review of 24 recent articles highlights a consistent picture that regulators, businesses and
consumers should be concerned about: when food is packaged in plastic and then microwaved, this significantly increases the risk of both microplastic and chemical release, and that these microplastics and chemicals will leach into the food inside the packaging.
And not just some, but a lot of microplastics and chemicals.
When polystyrene and polypropylene containers filled with water were microwaved after being stored in the fridge or freezer, one study found they released anywhere between 100,000-260,000 microplastic particles, and another found that five minutes of microwave heating could release between 326,000-534,000 particles into food.
Similarly there are a wide range of chemicals that can be and are released when plastic is heated. Across different plastic types, there are estimated to be around 16,000 different chemicals that can either be used or present in plastics, and of these around 4,200 are identified as being hazardous, whilst many others lack any form of identification (hazardous or otherwise) at all.
The research also showed that 1,396 food contact plastic chemicals have been found in humans, several of which are known to be hazardous to human health. At the same time, there are many chemicals for which no research into the long-term effects on human health exists.
Ultimately, we are left with evidence pointing towards increased release of microplastics and plastic chemicals into food from heating, the regular migration of microplastics and chemicals into food, and concerns around what long-term impacts these substances have on human health, which range from uncertain to identified harm.
The known unknowns of plastic chemicals and microplastics
The problem here (aside from the fact that plastic chemicals are routinely migrating into our food), is that often we don’t have any clear research or information on what long-term impacts these chemicals have on human health. This is true of both the chemicals deliberately used in plastic production (some of which are absolutely toxic, like antimony which is used to make PET plastic), as well as in what’s called non-intentionally added substances (NIAS).
NIAS refers to chemicals which have been found in plastic, and typically originate as impurities, reaction by-products, or can even form later when meals are heated. One study found that a UV stabiliser plastic additive reacted with potato starch when microwaved to create a previously unknown chemical compound.
We’ve been here before: lessons from tobacco, asbestos and lead
Although none of this sounds particularly great, this is not without precedence. Between what we do and don’t know, waiting for perfect evidence is costly both economically and in terms of human health. With tobacco, asbestos, and lead, a similar story to what we’re seeing now has played out before. After initial evidence suggesting problems and toxicity, lobbyists from these industries pushed back to sow doubt about the scientific validity of the findings, delaying meaningful action. And all the while, between 1950-2000, tobacco alone led to the deaths of around 60 million people. Whilst distinguishing between correlation and causation, and finding proper evidence is certainly important, it’s also important to take preventative action early, rather than wait for more people to be hurt in order to definitively prove the point.
Where to from here?
This is where adopting the precautionary principle comes in. This means shifting the burden of proof away from consumers and everyone else to prove that a product is definitely harmful (e.g. it’s definitely this particular plastic that caused this particular problem), and onto the manufacturer to prove that their product is definitely safe. This is not a new idea, and plenty of examples of this exist already, such as the EU’s REACH regulation, which is centred around the idea of “no data, no market” – manufacturers are obligated to provide data demonstrating the safety of their product in order to be sold.
Greenpeace analysis of 24 articles in peer-reviewed scientific journals found that the plastics we use to package our food are directly risking our health.
Heating food in plastic packaging dramatically increases the levels of microplastics and chemicals that leach into our food.
But as it stands currently, the precautionary principle isn’t applied to plastics. For REACH in particular, plastics are assessed on a risk-based approach, which means that, as the plastic industry itself has pointed out, something can be identified as being extremely hazardous, but is still allowed to be used in production if the leached chemical stays below “safe” levels, despite that for some chemicals a “safe” low dose is either undefined, unknown, or doesn’t exist.
A better path forward
Governments aren’t acting fast enough to reduce our exposure and protect our health. There’s no shortage of things we can do to improve this situation. The most critical one is to make and consume less plastic. This is a global problem that requires a strong Global Plastics Treaty that reduces global plastic production by at least 75% by 2040 and eliminates harmful plastics and chemicals. And it’s time that corporations take this growing threat to their customers’ health seriously, starting with their food packaging and food contact products. Here are a number of specific actions policymakers and companies can take, and helpful hints for consumers.
Policymakers & companies
- Implement the precautionary principle:
- For policymakers – Stop the use of hazardous plastics and chemicals, on the basis of their intrinsic risk, rather than an assessment of “safe” levels of exposure.
- For companies – Commit to ensure that there is a “zero release” of microplastics and hazardous chemicals from packaging into food, alongside an Action Plan with milestones to achieve this by 2035
- Stop giving false assurances to consumers about “microwave safe” containers
- Stop the use of single-use and plastic packaging, and implement policies and incentives to foster the uptake of reuse systems and non-toxic packaging alternatives.
Consumers
- Encourage your local supermarkets and shops to shift away from plastic where possible
- Avoid using plastic containers when heating/reheating food
- Use non-plastic refill containers
Trying to dodge plastic can be exhausting. If you’re feeling overwhelmed, you’re not alone. We can only do so much in this broken plastic-obsessed system. Plastic producers and polluters need to be held accountable, and governments need to act faster to protect the health of people and the planet. We urgently need global governments to accelerate a justice-centred transition to a healthier, reuse-based, zero-waste future. Ensure your government doesn’t waste this once-in-a-generation opportunity to end the age of plastic.
