Mexican citizens will go to the polls on 2 June 2024 to elect a new president, a new legislature and thousands of other local government officials.
Three candidates – two of whom are women – are contending to succeed the current leftwing president Andrés Manuel López Obrador. This could be the first time a woman is elected as president of Mexico.
In Mexico, presidential candidates can be put forward by a coalition of different political parties that share common goals and agendas.
Leading candidate in the polls Dr Claudia Sheinbaum represents a leftwing coalition, which includes Obrador’s ruling party, the National Regeneration Movement (Morena).
Xóchitl Gálvez represents several right and centre-left opposition parties, including the National Action Party. Jorge Álvarez Máynez is the centre-left party Citizen’s Movement candidate.
Mexico – a country with more than 126 million inhabitants and considered the second largest economy in Latin America, after Brazil – had the world’s 11th largest greenhouse gas emissions in 2018. (See Carbon Brief’s Mexico profile for more.)
Within the G20, Mexico is the only member that has not set a net-zero target. The country still strongly depends on oil, gas and coal. It faces several challenges in decarbonising its economy, implementing its national climate law and protecting its biodiversity through, for example, conserving its biodiversity agency.
In the interactive grid below, Carbon Brief compares the three presidential candidates’ proposals on energy, climate and biodiversity, based on manifestos, official webpages and other key official documents.
Each entry in the grid represents a direct quote from one or more of these documents.
Where does the country stand?
In its updated pledge to the UN about its climate actions and ambitions – its nationally determined contribution – Mexico says it contributes 1.3% of global greenhouse gas (GHG) emissions.
The country aims to cut its greenhouse gas emissions to 35% below a business-as-usual baseline by 2030, rising to 40% with international financial support.
The document says that emissions in 2020, not including land-based removals, stood at 804m tonnes of carbon dioxide equivalent (MtCO2e), with this rising to 991MtCO2e under the no-mitigation baseline.
This means hitting the lower target would entail cutting emissions to 25% below 2020 levels and the conditional goal a 35% reduction from the same starting point.
Its 2030 baseline is 991MtCOe with no mitigation efforts by the same year – reaching up to 40% of emissions reductions with international financial support.
Fossil fuels account for 86% of the total energy supply, while renewables make up only 8%.
In 2022, research and NGO partnership Climate Transparency concluded that Mexico “needs to adopt policies to phase out the use of fossil fuels [for example] coal and heavy oil while also reducing the social inequality gap”.
Sandra Guzmán is general director at the Climate Finance Group for Latin America and the Caribbean (GFLAC) and member of México resiliente – a group of civil-society organisations that sent the presidential candidates a proposed climate plan for the country.
This election is particularly important because of the need to rapidly cut global emissions this decade, she tells Carbon Brief. Guzmán adds:
“This is the most important six-year period to achieve climate goals. If someone with no interest in climate change comes to power, we would disdain and discard any commitment that Mexico has made and we will hardly be able to get on the path to compliance.”
What are the proposals?
Dr Claudia Sheinbaum is the candidate of the “let’s keep making history” coalition, made up of the ruling leftwing party, the National Regeneration Movement (Morena), the Labour party and the Green party. She holds a PhD in energy engineering and was head of the government of Mexico City from 2018 to 2023.
Sheinbaum’s roadmap for 2024-2030 aims to “decarbonise the energy matrix as quickly as possible”. However, the 381-page document says her administration would be “in line” with Obrador’s energy policy, which is based on energy self-sufficiency through the strengthening of the state-owned oil company Petróleos Mexicanos (Pemex), and the rehabilitation and acquisition of refineries. As well as the roadmap, the coalition’s manifesto does not mention any reference to net-zero.
Additionally, she has recently unveiled a plan to invest more than $13bn in new energy generation projects through 2030, according to Reuters. This would include increasing wind and solar power generation, as well as modernising five hydroelectric plants.

During the second presidential debate aired on Sunday 28 April, Sheinbaum restated her proposal to boost renewable energy sources. This includes domestic solar panels as well as growing electric transportation, while relying on gas and more combined-cycle plants for the energy transition.
The “let’s keep making history” candidate currently holds a substantial lead in the polls, but it is less clear whether her coalition will achieve the two-thirds majority in the legislature that it would need to enact its desired constitutional reforms.
Xóchitl Gálvez is the coalition candidate of several right and centre-left opposition parties, including the National Action Party, Institutional Revolutionary Party and Party of the Democratic Revolution. She is a computer engineer, an entrepreneur, a former mayor of Miguel Hidalgo borough in Mexico City from 2015 to 2018 and a former senator from 2018 to 2023.
Her coalition’s manifesto outlines a decarbonisation plan and pledges resources to encourage local and national energy transition plans. One of her most prominent energy proposals, outlined on her official webpage, is for the country to reach “net-zero carbon emissions” by 2050.
In the television debate, Galvez reaffirmed her commitment to achieving net-zero emissions by 2050, making Pemex’s business model more efficient and promoting clean energy rounds and electricity auctions. In a new proposal, she suggested that 50% of energy should come from renewable sources by 2030.
Jorge Álvarez Máynez is the candidate of the centre-left party Citizen’s Movement. He was deputy of Mexico’s congress for 2015-2018 and 2021-2024.
The party’s political platform seeks to establish a deadline for phasing out the use of fossil fuels. His party says it is committed to energy transition and recognises that this will involve replacing fossil fuel revenues, suggesting revenues from lithium, wind and hydropower production will make up the shortfall. While the manifesto pledges more ambitious emissions-cutting targets, it does not mention net-zero.
During the debate, Máynez reiterated some of the proposals outlined in his manifesto. This included the importance of transitioning to clean energy sources, such as solar and wind power, changing an oil tax into a green tax for electromobility and public transport, and closing a refinery and thermoelectric plant. He said his administration would install solar panels in all schools and hospitals, and boost sustainable development in the country’s south.
Missing issues
The second presidential debate in Mexico was the first ever to include climate change and sustainable development as one of its thematic areas. The three candidates discussed their proposals on mitigation and energy transition, while adaptation was little mentioned.
Mexico is currently grappling with water scarcity and drought. From October last year to April this year, the country’s 210 dams recorded storage figures below historical averages, according to Mexico’s national water commission. It adds that almost 80% of the country is currently going through some level of drought, with the northwest and center regions having it the worst. All candidates recognised both problems in the debate.
Sheinbaum said she would implement a national water plan focused on modernising agricultural irrigation, and recycling and boosting new water sources, such as seawater desalination. She also would maintain the agroecology program Sembrando Vida, questioned by experts for its impacts on deforestation and communities, and for not having environmental indicators in Central America.
Gálvez proposed creating a tri-national agency between Mexico, the US and Canada to tackle forest fires. On water, she said her government would give financial resources to the national water commission and treat 100% of wastewater by 2040.
Máynez plans to double the budget for water infrastructure, including dams, aqueducts and leak repairs. He proposes new conditions for companies setting up in the country, as most water is currently concessioned to large companies.
Guzmán tells Carbon Brief that, when it comes to climate policies, the biggest gaps in the candidates’ proposals are on adaptation and finance. She criticises candidates for not seeing climate change as a cross-cutting issue and for not earmarking funds or tax reforms to address the matter.
Biodiversity, loss and damage and the Escazú agreement – an agreement ratified by 16 countries from Latin America and the Caribbean to protect environmental defenders – are also absent, according to Anaid Velasco, GFLAC Mexico country director and member of México resiliente.
She tells Carbon Brief that biodiversity is “crucial”, since the Kunming-Montreal Global Biodiversity Framework mandates countries to submit their national biodiversity strategies (NBSAPs) this year. Mexico “should be working on it”, she says.

New Zealand moves to protect business with law curtailing climate litigation
New Zealand’s parliament has adopted a controversial new law blocking a whole avenue of climate litigation and shutting down its most advanced corporate lawsuit, which has been blamed by the government for shaking business confidence and investment.
The Climate Change Response (Tort Liability) Amendment Bill, expected to take effect in the coming days after it is formally signed by the Governor-General, prevents all current and future civil claims for climate loss or harm under tort law.
Justice minister Paul Goldsmith said last week that the aim was to give businesses “certainty around their climate change obligations”, noting it would not alter the government’s responsibilities under the Climate Change Response Act 2002 nor business obligations under the Emissions Trading Scheme.
“Our response to climate change is best managed by the Government at a national level and not through piece-meal litigation in the courts,” he added in a statement.
Such litigation, he said, “risks developing a new regime that contradicts the framework Parliament has already enacted” to tackle climate change.
Goldsmith singled out a key domestic climate lawsuit brought by Northland iwi leader and activist Mike Smith against six big companies: dairy firms Fonterra and Dairy Holdings, energy firms Genesis Energy and Z Energy, New Zealand Steel and coal mining firm BT Mining. A seventh original defendant, Channel Infrastructure, was dropped after it permanently decommissioned its Marsden Point oil refinery.
Smith argued that these companies had caused him harm under public nuisance and negligence law, as well as a third breach of a duty to cease contributing to climate change that has yet to be tested domestically. He did not seek financial compensation, instead asking for the companies to immediately stop emitting or contributing to net greenhouse gas emissions.
In one of the most advanced corporate climate accountability lawsuits in the world, a trial had been scheduled for April 2027 after the Supreme Court unanimously allowed the case to continue.
Corporate lobbying in the shadows
Smith described the passing of the bill as “deeply concerning”, particularly as it coincided with the Supreme Court hearing another of his climate lawsuits. In that case, Smith v Attorney-General, he argues that the government’s response to climate change and its impacts on Māori communities in particular breaches rights to life and culture.
“That timing raises profound questions about the separation of powers and the rule of law,” said Smith. “Whatever one’s view of the merits of these cases, it is deeply troubling when parliament intervenes to remove a legal pathway while the courts are actively considering fundamental questions about climate responsibility, rights and the crown’s obligations.”
The bill – which says that no person (including the government) can be found liable in tort for emissions-related climate change effects – followed major lobbying efforts by the companies defending themselves in Smith’s lawsuit. They outlined a proposed legal amendment in a briefing note to the government in 2024.
The centre-right government has been fiercely criticised over its lack of transparency in relation to this lobbying activity. The national ombudsman recently found that the Prime Minister’s Office effectively withheld information requested by the Environmental Law Initiative about meetings, discussions and conversations regarding Smith’s case.
Green groups fail to stop bill
The bill sparked huge concern among environmental campaigners in New Zealand and elsewhere. Greenpeace Aotearoa called it a “shocking abuse of executive power” and the vast majority of submissions to a parliamentary inquiry said it should be rejected.
But in the end, it was adopted with little resistance, moving relatively smoothly through parliament, passing its third reading by 67 votes to 53. Sam Bookman, climate law lecturer at Melbourne Law School, told Climate Home News he was not surprised by this, given that the coalition government has a secure majority.
A complaint has been made to the UN special rapporteur on climate change and human rights by Smith, the National Iwi Chairs Forum Pou Tikanga and youth coalition Climate Clinic Aotearoa over what they see as the government’s heavy-handed approach. Smith is also challenging the new law in yet another lawsuit.
“Pathetic”: New Zealand plans to barely cut emissions between 2030 and 2035
Bookman thinks it “very unlikely” that such a challenge will succeed, noting that New Zealand’s constitution is firmly anchored in parliamentary sovereignty.
But the expert in climate law does not see the bill as the end of legal action in the country, noting that New Zealand has a “sophisticated climate litigation landscape with a growing number of specialist and experienced lawyers and NGOs”.
The country is also approaching its next general election in November, and some opposition parties have pledged to restore access to the courts if elected.
Amanda Larsson, global project lead on agriculture for Greenpeace International, said: “This law deserves to be tested, and I strongly encourage the international climate litigation community to unite and help defend New Zealanders’ fundamental right to hold polluters accountable before this becomes a global blueprint.”
Copycat legislation on the rise
New Zealand’s move is part of a small but growing legislative effort to shut down climate litigation around the world.
In the US, Republican politicians introduced legislation in the House and Senate in April that would shield fossil fuel firms from climate liability lawsuits. Similar laws have already been passed at state level in Tennessee, Utah, Iowa and Louisiana.
The German state of Bavaria has put forward a similar proposal to the Federal Council, aiming to block private climate claims as well as the recognition and enforcement of foreign judgments imposing such liability. There are also proposals to limit available remedies and actions in the Netherlands and Belgium.
UN General Assembly backs “climate obligations” set by world’s top court
Bookman said he expects more efforts to counter climate damages litigation and advised plaintiffs to think about how to respond, including drawing on broader support in opposing them.
“Even though it’s very hard for plaintiffs to win these types of cases, companies are very eager to avoid the expense, embarrassment and political accountability that come even with unsuccessful lawsuits,” he said.

Indonesia’s nickel production cuts are not enough to create a sustainable industry
Bhima Yudhistira Adhinegara is the Executive Director of the Center of Economic and Law Studies (CELIOS), an Indonesia-based economic think tank. Muhammad Zulfikar Rakhmat is the Director of the China-Indonesia desk at CELIOS.
Indonesia produces around 60% of the world’s nickel, a metal used to manufacture batteries for electric vehicles (EVs) – more than any other country in the world. But in 2026, the government sharply reduced how much of its nickel can be extracted from the ground.
Production quotas were reduced by around 40% this year compared to 2025. Weda Bay, the largest nickel mine on Earth, had its allowance cut by more than 70% and exhausted its full-year quota by the end of May, halting mining entirely; it cannot resume large-scale extraction until next year unless regulators grant an extension.
The policy has sparked a vivid debate in Indonesian policy circles: how can the country shift its strategy from a decade of mining vast quantities of cheap nickel to producing a high-value and low-carbon material that the rest of the world wants for EV batteries.
The cuts aren’t a silver bullet to clean up Indonesia’s nickel industry, whose smelters are powered by coal – the most polluting fossil fuels. But alongside stricter enforcement of environmental rules, it is one side of efforts to produce more sustainable nickel for a premium.
Restricting Indonesia’s nickel output
Production quotas were introduced to stop the collapse of nickel prices because of oversupply in the market. Prices had fallen more than 40% in 2023 alone and kept sliding as Indonesian supply kept growing, hitting a four-year low of around $13,900 a ton in late 2025.
Critics called the recent tightening of production quotas proof that Indonesia’s nickel strategy has failed, arguing that the industry shouldn’t need to throttle its own output to survive. But when assessed against what the policy was supposed to do – push up nickel prices – it has worked. Prices jumped to $20,000 a ton in May, the highest since 2024.
Chinese industry groups representing companies that have invested billions to mine and refine the country’s nickel were furious, warning Indonesia’s president Prabowo Subianto that the cuts put $50 billion worth of investment at risk. But much of that Chinese capital is sunk into smelters and processing plants built specifically to run on Indonesian ore, and cannot simply be moved elsewhere. That gives Jakarta more room to hold its ground than the warning suggests.
Stronger environmental enforcement
Since the start of the year, Indonesia’s forestry task force has seized more than four million hectares of land from mines and plantations operating illegally in protected forests, collecting over two trillion rupiah ($113 million) in fines.
This included 148 hectares seized from Weda Bay for lacking a forestry permit. The share of nickel produced from illegal small-scale mining also fell from about a quarter in 2022 to roughly 10% by 2024.
The crackdown responds to serious environmental damages in the nickel industry. On Obi Island, a waste pond collapsed after heavy rain in June 2025, flooding three villages and killing a resident. Internal company tests found chromium-6 – a carcinogen – in the water, in quantities far above the legal limit. The footprint of another mine near Raja Ampat, which is home to some of the world’s richest coral reefs, grew 60-fold in just eight years.

The market is responding to early cleanup efforts. Low-carbon nickel now sells for a real premium, roughly $18,800 to $19,300 a ton compared with $17,900 to $18,300 otherwise, as carmakers seek to source cleaner materials to comply with the European Union’s new emissions rules for imports.
In turn, this is incentivising the industry to do more to green its operations. Vale Indonesia’s smelter in South Sulawesi now runs almost entirely on hydropower, for example.
None of this addresses coal use, however. Major Indonesian nickel producers still emitted an estimated 15 million metric tons of greenhouse gases in 2023. Indonesia may be cracking down on illegal mining and rewarding cleaner producers but it is still running its mines on the dirtiest fuel available.
Unequal benefits
For Indonesia to truly benefit from producing cleaner and high-value nickel, it needs to reap the economic benefits too. Although the industry has boosted the country’s economic growth, the reality on the ground tells a different story.
Konawe in Southeast Sulawesi is home to a major smelting complex. Growth in the district jumped from 6% to 22% between 2015 and 2023, driven almost entirely by the nickel industry, according to a study by the Lowy Institute study. At the same time, poverty levels increased slightly and unemployment remained unchanged.
In Halmahera, another epicentre of the nickel industry, spending by the poorest fifth grew just 5% between 2019 and 2022, compared with 28% for the wealthiest fifth, according to a separate study.
Part of the reason for this inequality is the system for transferring mining royalties to district authorities where the mines are located. In theory, they are entitled to the largest share. But in practice, payments are delayed, companies routinely dispute what they owe and royalties are pooled and distributed across a larger area.
The Natural Resource Governance Institute has found that decentralisation handed local governments power to approve new mines faster than they could build their capacity to manage them. Higher output raises national income on paper, but local governments remain constrained by fiscal rules and infrastructure costs that scale with mining.
None of this makes the 2026 quota cuts a mistake. Indonesia has every right to defend its pricing power over a resource it controls. But limiting extraction isn’t going to fix underlying issues around environmental enforcement and revenue-sharing. That requires rules that are consistently enforced, royalties that reach communities living by the mines, and a plan to wean smelters off coal.

Risk of “catastrophic” oil spill reaching Kimberley coast found in Woodside’s Scott Reef gas drilling plans
SYDNEY, Monday 24 August 2026 – New analysis of Woodside modelling released by Greenpeace Australia Pacific and Environs Kimberley has revealed the oil and gas corporation’s plans to drill at Scott Reef could cause an oil spill up to 30 times bigger than the 2009 Montara disaster, impacting the Kimberley coastline and reaching as far as Indonesia.
The new analysis details the “catastrophic” oil spill risk put to environmental regulators for approval by Woodside in its Browse to North West Shelf Project (Browse) plans, the worst-case scenario being a blowout directly below Scott Reef, polluting whale migratory pathways and covering isolated turtle nesting ground with oil condensate.
An FOI application (F348) revealed the federal environment department (DCCEEW) asked offshore oil and gas regulator NOPSEMA to look into the oil spill risk in 2025. NOPSEMA’s response to the application refused access to its report, and one document shows DCCEEW sought further advice this year.
Greenpeace and Environs Kimberley are calling on the Federal Government to publicly release the NOPSEMA report given the risk of an uncontrolled release of oil condensate from directly below Scott Reef.
Hannah Schuch, Senior Campaigner at Greenpeace Australia Pacific, said: “Woodside is aware that drilling at Scott Reef risks a massive oil spill that would have severe, far-reaching consequences. It appears environmental regulators are aware too.
“The state and federal governments need to take this risk from Woodside’s drilling plans seriously, as they could end up allowing the worst oil spill in Australian history.
“The pygmy blue whales that migrate up and down the WA coast with their newborns each year could be swimming and feeding in toxic, oil-slicked water. Woodside’s proposal to drill at Scott Reef is an environmental disaster waiting to happen, and the WA and federal governments have one surefire way to prevent catastrophe — reject Browse.”
Martin Prichard, Executive Director at Environs Kimberley, said: “A catastrophic oil spill by Woodside would be disastrous not just for marine life in the area but also for the Kimberley’s $500 million tourism industry.
“The state and federal governments will see five marine parks on the Kimberley coast included in the risk area of a catastrophic Woodside oil spill.
“The Montara oil spill was disastrous for West Timor with the toxic oil destroying seaweed farmers’ livelihoods. The Kimberley dodged a bullet with Montara, we were lucky the spill didn’t head our way. Myself and a crew flew over the Montara oil spill and followed it as far as we could. It was like a scene from a disaster movie.”
After the WA Environmental Protection Authority deemed Browse “unacceptable” due, in part, to oil spill risk, Woodside submitted a mitigation plan based on technology that has never been used “in anger”, a weakness stated in an independent expert review of the plan.
Professor Richard Steiner, independent oil spill expert, said: “A large offshore spill is impossible to effectively contain or recover. Historically, only 2-6% of total spill volume is recovered and the ecological injury from the release of toxic hydrocarbons in the sea can be severe, extensive, and long-term.
“Here in Alaska, government research concludes that several marine populations injured by the 1989 Exxon Valdez oil spill, including whales, fish, and seabirds, are still not recovering today, 37 years later. We should expect similar long-term ecological impacts in Western Australia if there were to be a major oil spill. The only sure way to avoid the risk of a catastrophic marine oil spill is to not develop oil and gas projects in marine environments.”
