Key developments

Food systems on the menu at COP29

MITIGATING METHANE: Yesterday was “food, agriculture and water day” at COP29, with a number of new initiatives and updates to existing initiatives announced. Down to Earth reported that more than 30 countries had endorsed the COP29 Declaration on Reducing Methane from Organic Waste, which includes a commitment to including sectoral targets in countries’ climate pledges. It added that the European Commission “welcomed the declaration, but did not endorse the pledge” due to a lack of time to consult with all member states.

PEACE AND HARMONIYA: The COP29 presidency also announced the Baku Harmoniya Climate Initiative for Farmers on Tuesday, in partnership with the UN Food and Agriculture Organization. The Harmoniya initiative has three stated priorities: creating a “streamlined knowledge hub” for improving collaboration and knowledge-sharing; making investment in food systems more attractive to both public and private investors; and empowering women and youth farmers to adapt to climate change. The declaration said: “Given the multitude of initiatives, there is a need for coherence, alignment and sharing of lessons learned to deliver greater impact.” No new commitments or funding accompanied Harmoniya’s release.

CHAMPIONING CHANGE: Food day also delivered an update on one of the key food-systems announcements from last year’s summit, the Alliance of Champions for Food Systems Transformation (ACF) – a group of six countries that had committed to taking stronger action on transforming food systems. During the summit, the ACF released a “progress snapshot” highlighting actions and policies each country had taken towards the priority action areas defined by the ACF. Tanzania confirmed its intention to join the coalition, the Guardian said. Vietnam also reportedly expressed their interest in joining.

AIM FOR THE SKY: Devex reported that the Agriculture Innovation Mechanism for Scale (AIM for Scale) initiative “has introduced its first package of investments”, which amounts to $1bn to strengthen weather forecasting for farmers. This “includes both new and existing investments from a consortium of global partners”, such as the World Bank, the US Agency for International Development and NASA. According to Emirates News Agency, investments in “climate-smart agriculture and food systems innovation” through the wider AIM for Climate initiative total $29.2bn to date. DeSmog previously reported concerns that the solutions pushed by AIM for Climate “are not the kinds of technology that will benefit small-scale farmers in Africa”.

‘Big ag’ in Baku

COP LOBBYING: Hundreds of “lobbyists for industrial farming” attended COP29, analysis from DeSmog and the Guardian found, with more than 200 delegates from agriculture companies and trade groups at the talks. Nearly 40% travelled with delegations of countries, such as Brazil, “giving them privileged access to diplomatic negotiations”, the Guardian noted. The number of industrial agriculture attendees dropped from “record highs” of 340 at last year’s summit, the newspaper said. They represent “some of the world’s largest agribusiness companies, including the Brazilian meatpacker JBS, the animal pharmaceuticals company Elanco and the food giant PepsiCo”, the Guardian said. DeSmog and the Guardian also revealed that a “record” 1,261 business and industry delegates registered to attend last month’s COP16 biodiversity summit.

OFFSET ADVICE: The UK released new guidelines for voluntary carbon and nature markets in Baku, BusinessGreen reported. These aim to give “clearer guidelines to companies involved in the purchase, sale and development of carbon offsets and nature credits”, the outlet said. One of the guidelines advises that credits should “complement” emissions-cutting and other climate action, not replace them. These represent a “vote of confidence in a largely experimental financial product that’s intended to protect biodiversity”, Bloomberg said. (Read Carbon Brief’s Q&A on biodiversity offsets.) Meanwhile, Brazil’s Congress signed off on a bill setting rules for a national carbon market, according to Reuters.

FARMER FUNDS: New analysis released during COP29 found that 14% of global public climate finance for agriculture and land use went to activities relevant to small-scale farmers in 2021-22. This is a small portion given that these farmers produce 70-80% of the food eaten in Africa and Asia, according to advisory company Climate Focus, which completed the analysis. Covering the report, Bloomberg spoke to Esther Penunia, secretary general of the Asian Farmers Association, who said: “[Climate change is] affecting our crops, our yields and therefore our incomes.” The Associated Press spoke to Penunia and others about climate finance for small farmers. Elsewhere, a policy paper found that “regenerative farming” has “shown promising results” in Africa and India, First Post said.

Spotlight

The ups and downs of Brazil’s new climate pledge

Brazil released its new climate pledge at COP29 last week, committing to cut greenhouse gas emissions by 59-67% by 2035. Here, Carbon Brief speaks to two Brazilian experts about the implications of the new nationally determined contribution (NDC).

Dr Ane Alencar is the director of science at the Amazon Environmental Research Institute. Claudio Angelo is the coordinator of international policy at Observatório do Clima, a Brazilian network of civil-society organisations. The interviews have been edited for length and clarity.

For more on Brazil’s NDC, see Carbon Brief’s just-published article on the five key takeaways.

Carbon Brief: What is your opinion on Brazil’s new NDC?

Ane Alencar: Even with all the difficulties we have in Brazil, there is a commitment of the government to actually move forward and be more ambitious [on climate change]. I think they did that…even though I think it could be a little bit more. But I think this is an important step.

Claudio Angelo: Policy-wise, it’s a pretty good NDC…We can say that the NDC reflects a shift of gear for Brazil and that’s important. But, again, we’re talking about policies. We’re not talking about the target. And the target of the NDC is very weak. You can’t say it is 1.5-aligned…There are things Brazil is already doing, such as tackling deforestation in the Amazon…So, I would say [the] direction of travel is right, but the speed is totally wrong.

CB: How does the NDC compare to previous pledges made by the Brazilian government?

CA: If you look at what Brazil has already committed to doing – for instance, zero deforestation, the methane pledge, [which is a] 30% reduction in methane, just the sheer pace of increase of renewable energies in the energy mix…There’s a new sustainable fuels legislation that was just passed this year. If you put all those things together, Brazil could aim much higher than the current limits…We’re hoping to get an increased ambition ahead of COP30. I think there’s [a] margin for that in the NDC. We will certainly push for [the new NDC] to be the ambition floor, not the ambition ceiling.

CB: Are the NDC promises to combat deforestation strong enough?

AA: The government has done a very good job in the past to reach that important reduction of deforestation…However, we do have to deal with the fact that there are people who still can deforest legally. And what would be the incentives for these people to not deforest? The incentives that exist today seem not to be enough.

CB: Are pledges to boost “sustainable agriculture” sufficient to meet climate goals?

AA: I think the agriculture sector is one that can provide lots of contribution, by improving their practices, investing in technologies to reduce the cattle contributions and also with soil management…If the Brazilian agriculture sector really goes in the direction of sustainability, then I think it’s possible to actually fulfil the NDC targets.

News and views

G20 TALKS: At the G20 summit, Brazil’s president, Luiz Inácio Lula da Silva, presented a new “alliance” to tackle poverty and hunger, Al Jazeera reported. It added that 81 countries signed the initiative. Before the summit, Joe Biden became the first US president to visit the Amazon rainforest, the Associated Press reported. In his speech, he said that the incoming administration of president-elect Donald Trump would not be able to halt his country’s progress on clean energy, the newswire added. Meanwhile, Mexico’s president, Claudia Sheinbaum, proposed allocating 1% of military expenditure to fund a global reforestation programme, which could free up $24bn annually to support 6m farmers to plant 15m hectares of trees.

‘GROUNDBREAKING’ DISCOVERY: The world’s largest coral, measuring more than 34 metres wide and 32 metres long, was discovered by a team of scientists in the Solomon Islands, Pasifika Environews reported. The outlet dubbed the discovery “groundbreaking” and noted that the coral structure is between 300 and 500 years old. It quoted Enric Sala, executive director of National Geographic’s Pristine Seas project, who stressed the urgency “for rich countries to invest significantly in reducing carbon emissions to combat threats like ocean warming and acidification” as negotiations at COP29 continue. Elsewhere, a “graveyard of corals” was found off an island on the Great Barrier Reef after months of extreme weather, the Guardian said.

AIRBORNE TOXIC EVENT: Air pollution in Delhi “hit 50 times the safe limit” this week, due in part to “farmers burn]ing] crop residue in agricultural areas”, according to the Associated Press. In response, the government has started enacting strict control measures, including banning most trucks from entering the city and moving school classes online. According to the Times of India, more than 1,250 agricultural fires were recorded in the state of Punjab on Monday, “the highest single-day tally of the season”. Delhi’s environment minister, Gopal Rai, said “the time has come for artificial rain to remove this smog cover and provide relief to the people”.

FARMER FURY: Thousands of farmers “descended” on Westminster in London to “protest a tax hike they say will deal a ‘hammer blow’ to struggling family farms”, the Associated Press reported. The UK government recently announced plans to get rid of a tax break that would introduce a 20% inheritance tax for farms worth more than £1m from 2026. (BBC News factchecked how many farms this might affect.) “Everyone’s mad” at this change, the co-organiser of the protest, Olly Harrison, told AP, adding that many “want to take to the streets and block roads and go full French”. (Farmers held a so-called “siege of Paris” earlier this year amid widespread EU farmer protests.) In ongoing farmer protests across the Channel, French farmers and their tractors blocked roads around the country to protest a trade deal between the EU and Mercosur countries in South America, according to Le Monde.

PUSHBACK: European lawmakers voted to “water down” and delay the EU’s anti-deforestation law, Reuters reported. The European Commission recently proposed a one-year delay for the law, which was due to take effect this December. This delay was backed by the European parliament in a 14 November vote, the newswire said, adding that politicians also voted to “add a new ‘no risk’ category of countries with far lighter controls”. This would “severely weaken” the law, BirdLife said in a statement, “making it inadequate to address global deforestation”. Elsewhere, BBC News said that Denmark signed off on the finer details of its world-first tax on farming emissions. (See Carbon Brief’s Q&A on the Danish plan.)

HIDDEN COSTS: Agrifood systems contain “hidden costs” – such as unaccounted for impacts on health and the environment – totalling around $12tn annually, the latest State of Food and Agriculture report from the UN Food and Agriculture Organization found. More than 70% of the costs stem from unhealthy dietary patterns and are linked to non-communicable diseases, such as heart disease and diabetes. The hidden environmental costs outlined in the report included emissions of greenhouse gases, nitrogen run-off and water pollution.

Watch, read, listen

GOING GREEN: Yale Environment 360 explored Brazil’s “bioeconomy”, which the country’s president hopes can act as a guide for other governments.

KITTENS CORRIDORS: A Mongabay podcast addressed why biological corridors are important for feline species in Latin America, such as puma, ocelot and jaguar.

PROMPTING TRANSITION: An NBC video showed how a nonprofit organisation helps farmers in North Carolina transition from traditional livestock to sustainable agriculture.

GO FISH: Scientists thought the Mekong giant salmon carp was extinct. But one scientist kept looking – and recently published evidence of its survival, the New York Times reported.

New science

  • New research in Ecological Economics found that climate change-induced migration of Nigerian herders seeking new grazing sites is a “key driver” of conflict between the herders and farmers. However, the study added, respondents who understood climate as the driving factor behind the migration were more likely to support policies that integrated herders into their community.
  • In the 2019-20 Australian “megafires”, plants and animals were worst affected in areas that were frequently burned or had recently burned in the past, according to a new Nature study. The “unprecedented” fires had a small, but overall negative impact on the abundance and occurrence of species, the researchers found. 
  • Reduced deforestation brings health benefits to Amazon populations, according to new research in Communications Earth and Environment. The study found that reduced deforestation pressure lowers the incidence of forest fires, lowering particulate matter concentrations and decreasing respiratory health problems for local communities.

Big fishing nations secure last-minute seat to write rules on deep sea conservation

Published

January 20, 2026

By

As a treaty to protect the High Seas entered into force this month with backing from more than 80 countries, major fishing nations China, Japan and Brazil secured a last-minute seat at the table to negotiate the procedural rules, funding and other key issues ahead of the treaty’s first COP.

The Biodiversity Beyond National Jurisdiction (BBNJ) pact – known as the High Seas Treaty – was agreed in 2023. It is seen as key to achieving a global goal to protect at least 30% of the planet’s ecosystems by 2030, as it lays the legal foundation for creating international marine protected areas (MPAs) in the deep ocean. The high seas encompass two-thirds of the world’s ocean.

Last September, the treaty reached the key threshold of 60 national ratifications needed for it to enter into force – a number that has kept growing and currently stands at 83. In total, 145 countries have signed the pact, which indicates their intention to ratify it. The treaty formally took effect on January 17.

    “In a world of accelerating crises – climate change, biodiversity loss and pollution – the agreement fills a critical governance gap to secure a resilient and productive ocean for all,” UN Secretary-General António Guterres said in a statement.

    Julio Cordano, Chile’s director of environment, climate change and oceans, said the treaty is “one of the most important victories of our time”. He added that the Nazca and Salas y Gómez ridge – off the coast of South America in the Pacific – could be one of the first intact biodiversity hotspots to gain protection.

    Scientists have warned the ocean is losing its capacity to act as a carbon sink, as emissions and global temperatures rise. Currently, the ocean traps around 90% of the excess planetary heat building up from global warming. Marine protected areas could become a tool to restore “blue carbon sinks”, by boosting carbon absorption in the seafloor and protecting carbon-trapping organisms such as microalgae.

    Last-minute ratifications

    Countries that have ratified the BBNJ will now be bound by some of its rules, including a key provision requiring countries to carry out environmental impact assessments (EIA) for activities that could have an impact on the deep ocean’s biodiversity, such as fisheries.

    Activities that affect the ocean floor, such as deep-sea mining, will still fall under the jurisdiction of the International Seabed Authority (ISA).

    Nations are still negotiating the rules of the BBNJ’s other provisions, including creating new MPAs and sharing genetic resources from biodiversity in the deep ocean. They will meet in one last negotiating session in late March, ahead of the treaty’s first COP (conference of the parties) set to take place in late 2026 or early 2027.

    China and Japan – which are major fishing nations that operate in deep waters – ratified the BBNJ in December 2025, just as the treaty was about to enter into force. Other top fishing nations on the high seas like South Korea and Spain had already ratified the BBNJ last year.

    Power play: Can a defensive Europe stick with decarbonisation in Davos?

    Tom Pickerell, ocean programme director at the World Resources Institute (WRI), said that while the last-minute ratifications from China, Japan and Brazil were not required for the treaty’s entry into force, they were about high-seas players ensuring they have a “seat at the table”.

    “As major fishing nations and geopolitical powers, these countries recognise that upcoming BBNJ COP negotiations will shape rules affecting critical commercial sectors – from shipping and fisheries to biotechnology – and influence how governments engage with the treaty going forward,” Pickerell told Climate Home News.

    Some major Western countries – including the US, Canada, Germany and the UK – have yet to ratify the treaty and unless they do, they will be left out of drafting its procedural rules. A group of 18 environmental groups urged the UK government to ratify it quickly, saying it would be a “failure of leadership” to miss the BBNJ’s first COP.

    Finalising the rules

    Countries will meet from March 23 to April 2 for the treaty’s last “preparatory commission” (PrepCom) session in New York, which is set to draft a proposal for the treaty’s procedural rules, among them on funding processes and where the secretariat will be hosted – with current offers coming from China in the city of Xiamen, Chile’s Valparaiso and Brussels in Belgium.

    Janine Felson, a diplomat from Belize and co-chair of the “PrepCom”, told journalists in an online briefing “we’re now at a critical stage” because, with the treaty having entered into force, the preparatory commission is “pretty much a definitive moment for the agreement”.

    Felson said countries will meet to “tidy up those rules that are necessary for the conference of the parties to convene” and for states to begin implementation. The first COP will adopt the rules of engagement.

    She noted there are “some contentious issues” on whether the BBNJ should follow the structure of other international treaties such as the Convention on Biological Diversity (CBD), as well as differing opinions on how prescriptive its procedures should be.

    “While there is this tension on how far can we be held to precedent, there is also recognition that this BBNJ agreement has quite a bit to contribute in enhancing global ocean governance,” she added.

    Climate at Davos: Energy security in the geopolitical driving seat 

    Published

    January 20, 2026

    By

    The annual World Economic Forum got underway on Tuesday in the Swiss ski resort of Davos, providing a snowy stage for government and business leaders to opine on international affairs. With attention focused on the latest crisis – a potential US-European trade war over Greenland – climate change has slid down the agenda.

    Despite this, a number of panels are addressing issues like electric vehicles, energy security and climate science. Keep up with top takeaways from those discussions and other climate news from Davos in our bulletin, which we’ll update throughout the day.

    From oil to electrons – energy security enters a new era

    Energy crises spurred by geopolitical tensions are nothing new – remember the 1970s oil shock spurred by the embargo Arab producers slapped on countries that had supported Israel during the Yom Kippur War, leading to rocketing inflation and huge economic pain.

    But, a Davos panel on energy security heard, the situation has since changed. Oil now accounts for less than 30% of the world’s energy supply, down from more than 50% in 1973. This shift, combined with a supply glut, means oil is taking more of a back seat, according to International Energy Agency boss Fatih Birol.

    Instead, in an “age of electricity” driven by transport and technology, energy diplomacy is more focused on key elements of that supply chain, in the form of critical minerals, natural gas and the security buffer renewables can provide. That requires new thinking, Birol added.

    “Energy and geopolitics were always interwoven but I have never ever seen that the energy security risks are so multiplied,” he said. “Energy security, in my view, should be elevated to the level of national security today.”

    In this context, he noted how many countries are now seeking to generate their own energy as far as possible, including from nuclear and renewables, and when doing energy deals, they are considering not only costs but also whether they can rely on partners in the long-term.

      In the case of Europe – which saw energy prices jump after sanctions on Russian gas imports in the wake of Moscow’s invasion of Ukraine – energy security rooted in homegrown supply is a top priority, European Commission President Ursula von der Leyen said in Davos on Tuesday.

      Outlining the bloc’s “affordable energy action plan” in a keynote speech at the World Economic Forum, she emphasised that Europe is “massively investing in our energy security and independence” with interconnectors and grids based on domestically produced sources of power.

      The EU, she said, is trying to promote nuclear and renewables as much as possible “to bring down prices and cut dependencies; to put an end to price volatility, manipulation and supply shocks,” calling for a faster transition to clean energy.

      “Because homegrown, reliable, resilient and cheaper energy will drive our economic growth and deliver for Europeans and secure our independence,” she added.

      Comment – Power play: Can a defensive Europe stick with decarbonisation in Davos?

      AES boss calls for “more technical talk” on supply chains

      Earlier, the energy security panel tackled the risks related to supply chains for clean energy and electrification, which are being partly fuelled by rising demand from data centres and electric vehicles.

      The minerals and metals that are required for batteries, cables and other components are largely under the control of China, which has invested massively in extracting and processing those materials both at home and overseas. Efforts to boost energy security by breaking dependence on China will continue shaping diplomacy now and in the future, the experts noted.

      Copper – a key raw material for the energy transition – is set for a 70% increase in demand over the next 25 years, said Mike Henry, CEO of mining giant BHP, with remaining deposits now harder to exploit. Prices are on an upward trend, and this offers opportunities for Latin America, a region rich in the metal, he added.

      At ‘Davos of mining’, Saudi Arabia shapes new narrative on minerals

      Andrés Gluski, CEO of AES – which describes itself as “the largest US-based global power company”, generating and selling all kinds of energy to companies – said there is a lack of discussion about supply chains compared with ideological positioning on energy sources.

      Instead he called for “more technical talk” about boosting battery storage to smooth out electricity supply and using existing infrastructure “smarter”. While new nuclear technologies such as small modular reactors are promising, it will be at least a decade before they can be deployed effectively, he noted.

      In the meantime, with electricity demand rising rapidly, the politicisation of the debate around renewables as an energy source “makes no sense whatsoever”, he added.

      In six generations, Jake Christian’s family had never seen a fire like the one that blazed toward his ranch near Buffalo, Wyoming, late in the summer of 2024. Its flames towered a dozen feet in the air, consuming grassland at a terrifying speed and jumping a four-lane highway on its race northward.
