The mass deployment of electric vehicles, solar panels and wind turbines around the world has raised a pressing question for environmentalists and human rights defenders: how to ensure that the materials needed to manufacture cleantech are produced sustainably and responsibly?
From the Democratic Republic of Congo and Zambia to Chile and Indonesia, the race to mine more minerals pivotal to the energy transition such as lithium, nickel, cobalt and copper has led to growing environmental destruction, deforestation and social conflict.
The cleantech companies that use them are increasingly coming under pressure from end-product manufacturers and governments to demonstrate that the metals and minerals entering their supply chains have been sourced responsibly without contributing to conflict or human rights abuses.
But transparent and verified information about the origins of these materials is often in short supply.
“Whether it be the iron that’s going into steel, the rare earths going into magnets, the lithium going into batteries, this is a sector that has largely had no transparency with respect to their supply chains,” Cameron Scadding, CEO and managing director at Source Certain, told Climate Home News.
That is what the Western Australian company is working to change.
Source Certain specialises in verifying the origin of minerals, food and timber using scientific tools and forensic investigation techniques. By reading the chemistry of a piece of ore or a mineral inside a product, it can trace it back to the mine where it was extracted.

“If we genuinely want to be better to the environment, we absolutely cannot do that without knowing where this stuff comes from… how it’s been mined or how it’s been processed,” Scadding said in an interview from his home in Perth.
The technique allows companies, regulators and governments to verify information about the origin and sourcing of a product. This can help expose illicit trade, hold companies’ sustainability claims to account and could help respond to mounting calls to make mineral supply chains more transparent and traceable.
A supply chain integrity test
A forensic and analytical chemist, Scadding founded Source Certain more than a decade ago with a focus on the origin of food and agricultural products.
Since then, Source Certain has helped expose the presence of Chinese tomatoes picked using forced labour in “Italian” tomato puree, found mislabelled seafood on supermarket shelves, and helped to prevent Ukrainian wheat stolen from Russian-controlled territories finding a route to market.
Consumers may not share the same emotional connection with how their food is produced and where the rare earths in their EVs come from, but for Scadding, the challenge is equally urgent.
“The whole idea of the energy transition is that we can, through technology, move away from oil and gas and carbon-intensive industries. But that actually stacks up [only] if we do it ethically and sustainably, because otherwise it’s a roundabout of sustainability problems.”
Source Certain verifies companies’ claims on the origin of their minerals by analysing a sample and comparing it to the geological profile of the mine where it was supposedly extracted.
To do this, it uses a technology known as fingerprinting, which was first developed to trace the source of gold and help identify fake metal.

Africa must reap the benefits of its energy transition minerals
In the rush to exploit minerals needed to fight climate change, African leaders should harness their natural wealth for the continent’s development
As minerals form, they absorb traces of elements from their environment. By analysing this elemental profile and creating a distinctive pattern, scientists can match the mineral to the specific place where it came out of the ground and provide context over how it was mined.
This investigative approach makes it possible to verify a product’s origin along different points of the supply chain in what Scadding described as “an integrity test”. Source Certain then supports the company checking the materials to understand and act on its findings.
In principle, the same technology can be used to find out, for example, where in the world a piece of copper has come from without any additional information. But that would require a much lengthier and more complicated forensic investigation, said Scadding.
Looking for mines and factories’ fingerprints
Source Certain is already offering the service at scale for the gold industry. The work is more complex for metals such as lithium that are transformed before they are used in technologies like batteries. But it is still possible to verify the integrity of the product at various points of the mineral’s transformation, said Scadding.
Mines, refineries and factories all leave their fingerprint on the materials – a trail of clues that can help confirm whether what the company claims about the item’s provenance is true.
But doing this can only help improve sustainability if the company has measures in place to control what enters its supply chain. “We can’t go in and make a supply chain have integrity. All we can do is test and verify,” Scadding told Climate Home.
“If you do not know where your product has come from and you cannot verify it, then there should be no claims on that product from a sustainability basis,” said Scadding. Otherwise, he added, “you’re almost certainly greenwashing”.
The case for more regulation
The Australian firm already counts miners, refiners and end-product manufactures among its customers, including in the rare earths industry, which supplies materials used in magnets for EV motors and wind turbines. In 2021, it partnered with British company Cornish Lithium to verify the origin of UK-mined lithium in batteries.
Now, with backing from British venture capital firm Greensphere, the company wants to scale and expand its presence in the UK and EU markets, which have adopted more stringent due diligence requirements for supply chains – although some EU regulations are at risk of being watered down.
Globally, Scadding said some progress has been made to improve the transparency of mineral supply chains: due diligence regulation is catching up and companies are increasingly motivated to manage the risks to their business.

Industry says carbon capture still an expensive last resort to cut emissions
Carbon capture players told a recent global conference that the technology remains a costly way to reduce CO2 and needs more government support
But more could still be done to understand the environmental and social risks these supply chains carry.
A recent assessment by the International Energy Agency and the OECD found that measures encouraging traceability in critical mineral supply chains are on the rise but mostly affect manufacturing companies and retailers at the end of the value chain.
In addition, very few require scientific verification of the materials’ origins.
Knowing where a product is from is fundamental to any due diligence framework, said Scadding.
“What we want regulation to do is make it mandatory that companies actually go and look at what is happening within their supply chains and check what they are being told,” he said. That could include scientific testing alongside other due diligence measures, such as audits and creating digital documentation trails of an item’s journey along the supply chain.
“Scientific testing provides unique insights and in most cases – a surprise to most of our clients – is that it is more cost-effective and easier to implement than most of the other digital offerings,” he added.

The company tracking energy transition minerals back to the mines
The global roadmap on transitioning away from fossil fuels now being developed should be a “continuing conversation” which is part of UN climate talks, not just a one-off report, several governments told the Brazilian COP30 Presidency on Friday in Bonn.
During a 90-minute exchange of views at the annual mid-year climate talks in Germany, several European governments and the Marshall Islands said the roadmap that Brazil is due to finish by November should be incorporated into the official negotiations.
Any such push is likely to be resisted by nations whose economies are reliant on fossil fuel production. While Russia did not speak on Friday, it has said in earlier written submissions that the roadmap should not be referenced in any document approved by governments at UN climate talks.
At COP30 last year, Brazil tried to get governments to agree to produce a roadmap on how to transition away from fossil fuels but the proposal did not win consensus, with major nations like Saudi Arabia and Russia opposed.
Feedback in Bonn
To save the day, Brazil’s COP30 president André Aranha Corrêa do Lago promised at the closing plenary in Belem to draw up a voluntary roadmap in consultation with interested governments. Over 20 countries have officially submitted their opinions on this roadmap and, in Bonn on Friday, Corrêa do Lago sought their views – and those of civil society – in person after the presidency presented its findings so far.
The roadmap will also incorporate outcomes from the first global conference on transitioning away from fossil fuels held in Santa Marta, Colombia, in April and attended by around 60 countries.
A negotiator for the Marshall Islands told Friday’s meeting that at COP31 this year all governments should “welcome the collaborative effort behind the roadmap and the Santa Marta conference and for this work to be taken on to COP32 and beyond”.

COP31 leaders unveil global targets, with spotlight on electrification
Co-hosts Türkiye and Australia want countries to sign on to global targets in three of their priority areas for this year’s COP climate negotiations
A spokesperson for Switzerland said on behalf of a group of nations which includes South Korea and Mexico that the roadmap must be a “sustained process, not a one-off report” and “we would welcome an ongoing platform for dialogue, for learning and cooperation including among fossil-fuel production countries”.
“We expect more than a document, rather a process whereby we come together to develop concrete steps, recommendations and tools to prepare for the transitions,” she said, calling on the COP31 co-presidents Australia and Turkiye and COP32 host Ethiopia to “take up the leadership” for implementing the roadmap”.
Global stocktake response
France’s negotiator said the roadmap “is a process and we will need continuing discussions” as “implementation needs time”, while the UK called for a “continuing conversation, including as we head towards the second [global stocktake]”.
The global stocktake (GST) is an official five-yearly report into how the world’s governments are doing on their Paris Agreement goal to limit global warming to 1.5C above pre-industrial temperatures.
The second stocktake will be published in 2028 and governments are likely to negotiate a response to it, which could include new commitments to reduce emissions, at COP33 that year. The response to the first global stocktake included the landmark COP28 commitment to transitioning away from fossil fuels in energy systems.
“Even though it’s not a formal part of the negotiation agenda, the roadmap can be a key input for the entire information-gathering phase of the second GST,” Enrique Maurtua Konstantinidis, an independent climate policy consultant, explained to Climate Home News.
“The key is for countries not to focus the discussion on defending the roadmap itself, but rather on its content, which is what truly matters,” he added.
At the Bonn event, civil society organisations also supported continuing the roadmap inside the formal climate process.
Natalie Jones, policy adviser for the International Institute for Sustainable Development, told Climate Home News the roadmap should be “an ongoing dialogue where countries can exchange their experiences, best practices and continue implementing the [transitioning away from fossil fuels] consensus”.
Russian resistance
But economies reliant on fossil fuel production are likely to oppose incorporating the roadmap into negotiations in Bonn and at COP summits. Russia’s written submission to Brazil’s consultation says the roadmap was not agreed by governments at COP30.
It says such work should therefore take place on the margins of the UNFCCC process, adding that “ the inclusion of any references to the “Roadmap” in the agenda or in official or informal documents” at Bonn or COP “would constitute a deviation from previously agreed consensus outcomes”.
Other major oil and gas producers like Saudi Arabia have not made written or spoken submissions and the US, as it has left the Paris Agreement, is not involved in discussions. But countries other than Russia are likely to resist incorporating the roadmap into official talks.
The submission by Japan, which is not a major producer of fossil fuels but consumes them from overseas, suggests nervousness about the roadmap. It asks Brazil for clarity on how the roadmap is “envisaged to be utilised” and argues that as many countries continue to rely on fossil fuels for electricity, a full and fast shift to “full decarbonisation” is “challenging.
After Friday’s event, Corrêa do Lago told Climate Home News that “the suggestions and the key milestones of the roadmap are not clear yet”. He added that the next step for the COP30 presidency will be to “sit down in July and August to really prepare” the content.
The veteran Brazilian diplomat added that the roadmap will have a section on the challenges of the transition and another section on solutions.
National fossil fuel roadmaps
Brazil, as COP30 president, is drawing up the global roadmap but its leader Lula da Silva has also ordered his officials to draw up a national roadmap.
In April, France became the first and so far only nation to produce a roadmap, which amalgamated different existing energy and decarbonisation plans and targets. Colombia is reportedly drawing up a roadmap too, based on a draft document by academics.
On Friday, a coalition of nearly 100 civil society organisations called on the COP31 co-presidents Australia and Türkiye to both come up with national roadmaps in order to “lead by example”. Türkiye produces about a third of its electricity from coal, while Australia is the world’s third-largest fossil fuel exporter, the NGOs said.
But in the Brazil-led consultation meeting, a Norwegian negotiator downplayed the importance of separate national roadmaps for transitioning away from fossil fuels.
While they can “have a supporting role”, the official said countries’ nationally determined contributions (NDCs) “must remain the primary vehicle for driving global climate transition.”
NDCs are climate plans, usually containing emissions reduction targets, which the Paris Agreement states governments must update with higher ambition every five years.

DeBriefed 12 June 2026: El Niño begins | COP31 hosts eye electrification | Atlantic current monitoring at risk
Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
El Niño begins
‘DOMINO WEATHER’: The natural weather phenomenon El Niño, which can raise global heat and “bring domino weather effects across the planet”, is now underway, the US National Oceanic and Atmospheric Administration (NOAA) declared on Thursday, reported the Washington Post. The Japanese Meteorological Administration also identified the start of El Niño on Wednesday, said Bloomberg. According to the Japanese weather agency, the event is “expected to intensify in the coming months and become very strong later in the year, persisting into at least December”, reported the outlet.
‘SUPER EVENT’: BBC News reported that “many forecasts suggest this could end up as a so-called ‘super’ El Niño” and be “among the strongest ever recorded”. It added: “Coming on top of decades of human-caused warming, it could bring another record-hot year – most likely in 2027 – with disruption to weather, food supplies and economies running well into that year.”
COP31 hosts eye electrification
‘35 BY 35’: COP31 hosts Turkey and Australia have called for countries to support a target of electrifying 35% of global energy use by 2035, reported Politico. Speaking at climate talks in Bonn, Germany, Turkish minister Murat Kurum said that electrification would be a “flagship priority” at the COP31 summit, noted the publication. Kurum added that “electrifying daily life, from transport to buildings and industry” could “protect families and businesses from volatile energy markets”, said the outlet.
WASTE AND BUILDINGS: Climate Home News reported that electrification was one of three priorities unveiled by the COP31 hosts, with the other two being waste and buildings. On buildings, the COP31 hosts “quietly overhauled [their] goal”, Climate Home News said. It reported: “An initial press statement on Monday set out a target ‘to achieve at least a 25% increase in energy efficiency in buildings by 2035’. But…on Tuesday, that was replaced with a different goal to ‘reduce energy consumption intensity in the building sector by at least 25% by 2035’.”
‘HARDEST’ CHALLENGE: Elsewhere in Bonn, UN climate chief Simon Stiell said “governments must stop revisiting climate commitments and start delivering on them”, South Africa’s Mail and Guardian reported. It quoted Stiell as saying: “Tackling the global climate crisis is the hardest but most important thing humanity has ever tried to do together…We are not yet where we need to be. But we are somewhere we have never been before.”
Around the world
- ETS EXTRA: The EU has agreed “stronger” price controls on “ETS2”, its planned trading system for heating and transport emissions, according to Reuters.
- OCEAN STRESS: The rate of sea level rise has doubled in 10 years amid “severe and accelerating” pressures on oceans, said a UN report covered by Time.
- CLIMATE MIGRANTS: Donald Trump’s “immigration crackdown is largely targeting people from the countries most vulnerable to displacement from climate-driven disasters”, according to Guardian analysis.
- ULTRA-RICH: Investments by the world’s ultra-rich in 2022 are linked to nearly $1tn in climate damages, according to a Greenpeace Africa analysis covered by BusinessGreen.

Captured
Solar power has overtaken gas in Asia to become the region’s third largest electricity source behind coal and hydropower, according to Carbon Brief analysis of data from the thinktank Ember. Solar became the third largest electricity source for Asia on an annual basis in April 2026, according to the analysis. In the year to April 2026, solar generated 1,727 terawatt hours (TWh), while gas generated 1,711TWh, it added.
Spotlight
Atlantic current monitoring at risk
This week, Carbon Brief reports on how Trump plans could disrupt efforts to track a major ocean current.
The Irminger Sea, a patch of frigid ocean east of Greenland, plays an outsized role in the Earth’s climate.
Here, surface water that has travelled thousands of kilometres from the tropics grows cold and dense enough to sink to the ocean’s depths – a transformation that must occur for the water to begin a long journey back to the southern hemisphere.
This makes the Irminger Sea an “action centre” for the mighty Atlantic Meridional Overturning Circulation (AMOC), the vast system of ocean currents that keeps temperatures in Europe mild.
Last week, the US government announced plans to dismantle ocean moorings installed in the Irminger Sea which, among other things, collect data on the health of the AMOC.
This came as part of a programme to “descope” the Ocean Observatories Initiative, a $368m network of ocean sensors installed in the Pacific and Atlantic oceans.
Two of the moorings earmarked for removal in the Irminger Sea form part of an internationally funded, trans-Atlantic AMOC monitoring array, known as OSNAP, that stretches from Canada to Scotland.
Experts told Carbon Brief the move by the Trump administration highlights the vulnerability of AMOC observation systems around the world. These deep-sea moorings – scattered across the Atlantic – collect real-time data on, among other things, ocean current, temperature, pressure and biochemistry.
Prof Penny Holliday, chief scientific officer of the UK National Oceanography Centre, told Carbon Brief that the OSNAP array, as well as the RAPID array at 26N, are “entirely dependent” on research grants that have to be “continually reapplied for”.
“Funding is perilous all the time,” she said.
A report prepared last month by scientists for Nordic ministers exploring the security of funding for AMOC observing systems warned that RAPID and OSNAP were in “critical condition” and faced “material exposure over an 18-month horizon”. Meanwhile, other key basin-wide and global components of the global AMOC observing system were rated as “at risk”.
It is not just US funding that is uncertain. The report notes, for example, that the five-yearly funding the UK provides to RAPID and OSNAP is “at risk from 2027 due to year-on-year budget reductions” at the Natural Environmental Research Council.
(RAPID is funded by the US and UK, whereas OSNAP is backed by five different countries, with the US contributing half of the total financial support.)
Report co-author Dr Femke de Jong from the Royal Netherlands Institute for Sea Research told Carbon Brief that “continued AMOC observations” are under pressure in “multiple countries”. She said:
“While the risk of a declining AMOC to society is starting to be recognised, there is not yet a system or institution in place to guarantee a way to monitor it.”
AMOC monitoring arrays are still in their infancy – RAPID, the oldest, was launched in 2004. Two decades of data captured so far shows that the AMOC is slowing down. However, scientists will need many more years of data to be able to confidently link the decline to climate change, rather than natural variability in the ocean.
NOC’s Holliday points to the disconnect between scientific and funder timelines:
“The timescale of observations needed in order to be able to detect a climate change signal from the very naturally variable ocean is around 40-60 years…. [And yet], in the Netherlands, they have to apply for a new grant for their ocean moorings every two years. They are going to have to do that for 40 years.
“This is a very inefficient way of getting funding for what should be critical infrastructure.”
