On 1 February, India’s finance minister Nirmala Sitharaman unveiled the government’s budget for 2026, which included a new $2.2bn funding push for carbon capture technologies.
In the absence of its new international climate pledge under the Paris Agreement, the budget offers a glimpse into the key climate and energy security priorities of the world’s third-largest emitter, amid increasing geopolitical tensions and trade challenges.
While Sitharaman’s budget speech did not mention climate change directly, she said: “Today, we face an external environment in which trade and multilateralism are imperilled and access to resources and supply chains are disrupted.”
Sitharaman emphasised that “new technologies are transforming production systems while sharply increasing demands on water, energy and critical minerals”.
The budget sets out: support for the mining and processing of critical minerals and rare earths; import duty exemptions for nuclear power equipment; and support for renewables, particularly rooftop solar.
However, unlike in some previous years, the 2026 budget does not include specific climate adaptation measures.
Below, Carbon Brief runs through five key climate- and energy-focused announcements from the budget.
- Carbon capture, utilisation and storage
- Critical minerals and rare earth ‘corridors’
- Nuclear energy
- Renewables
- Adaptation
Carbon capture, utilisation and storage
The biggest climate-related budget announcement was $2.2bn to support carbon capture, utilisation and storage (CCUS) technologies in India over the next 5 years.
These are technologies that capture carbon dioxide (CO2) as it is released, then use or store it underground or under the sea.
This funding is aimed at decarbonising five of India’s high-emitting industrial sectors – power, steel, cement, refineries and chemicals. These sectors are “staring at the risk” of coming under the EU’s carbon adjustment mechanism (CBAM), even after a recent EU-India trade deal, according to Sitharaman.
The funding is meant to align with a roadmap released last year that sees CCUS as a “core technological pillar” of India’s 2070 net-zero strategy, particularly for “decarbonising sectors where viable alternatives are limited”, notes the government’s roadmap.
According to the Intergovernmental Panel on Climate Change (IPCC) sixth assessment report, however, the need for CCUS to mitigate industrial emissions “may be overestimated”, compared to measures such as energy and material efficiency and electrification.
Speaking to Carbon Brief, Dr Vikram Vishal, a professor of earth sciences at the Indian Institute of Technology, Bombay (IIT-B),, describes the budget move as a “big welcome step for industrial decarbonisation and India’s net-zero ambitions as a whole”.
Vishal says that the funding could go towards getting “big demonstration plants to near-commercial plants” that could entail even bigger investments in the future.
He tells Carbon Brief:
“India is blessed with both onshore and offshore availability for carbon storage. But while utilisation exists, storage has not happened, per se, even at a decent scale. We [would] need to build transportation infrastructure from the point source of capture at scale, on land and offshore. While offshore storage is very low risk, onshore presents a closer proximity to emission sources.”
However, that could also mean closer proximity to densely populated or protected areas.
Vishal adds that India has a very large theoretical storage potential, even a quarter of which would allow for up to 150bn tonnes of CO2 to be stored. This could sustain CCUS for hundreds of years, Vishal says, adding: “And by that time, the energy transition would have happened, right?”
Critical minerals and rare-earth ‘corridors’
Mining, sourcing and processing “critical minerals” and rare earths is another key area of India’s 2026 budget.
It proposes establishing “dedicated rare-earth corridors” in the “mineral-rich” coastal states of Odisha, Kerala, Andhra Pradesh and Tamil Nadu to “promote mining, processing, research and manufacturing”. These corridors are intended to complement a $815m rare-earth permanent-magnet scheme announced in November.
In addition, the budget supports “incentivising prospecting and exploration” for rare-earth minerals, such as monazite, as well as others that the government wants to include in its list of “critical minerals”.
Last week, for instance, India classified coking coal – which is predominantly used in making steel – as a “critical and strategic mineral”, removing regulatory measures such as the need to consult affected communities before developing new mines.
Sehr Raheja, programme officer at New Delhi thinktank Centre for Science Environment, tells Carbon Brief that “moving up the critical-minerals value chain” is “increasingly essential” for the energy transition in developing countries.
She adds that some of the measures announced in India’s budget “point in that direction”, explaining:
“Globally, developing countries often stay stuck in the extraction stages of value chains and capture the least value. While duty exemptions for critical mineral processing and battery manufacturing signal intent to build domestic manufacturing capacity, the extent to which these new efforts deliver sustained value will only become apparent over time.”
Rahul Basu, research director at the Goa Foundation, which advocates for “intergenerational equity” in mining, tells Carbon Brief:
“Rare earths are not particularly rare. What is difficult is separating and refining them. China imports ore from around the world, including [the] US. Their competitive advantage lies in processing, including the ability to tolerate high pollution levels.
“India should perfect the processing technology with imported ores first. It is the critical piece. Not mining. We seem to want to mine the same beaches that are already seeing sea-level rise.”
Nuclear energy
The Indian government has also lifted customs duties on imports of nuclear power equipment within the 2026 budget.
Under the changes, equipment for all nuclear power plants will not be subject to customs duties until 2035, irrespective of capacity.
The announcement follows India enacting a landmark new nuclear act, dubbed the “Shanti” act, in December 2025. This seeks to privatise and invite foreign participation in the country’s nuclear energy sector, which has been largely state-run for decades and has a long history of public protests over safety and land-acquisition concerns.
The Shanti act – which is an acronym for “sustainable harnessing and advancement of nuclear energy for transforming India” – aims to help India increase its nuclear capacity tenfold to 100 gigawatts (GW) by 2047.
This coincides with 100 years since India’s independence and is “the year India aims to attain developed-nation status”, according to prime minister Narendra Modi.
Renewables
Support for renewables in India’s budget this year is significant, but “uneven”, experts tell Carbon Brief.
Allocations to India’s Ministry of New and Renewable Energy (MNRE) grew by 24% to a “record high” in the 2026 budget, with the bulk going to the prime minister’s flagship rooftop solar scheme. The government also cut import duties on lithium-ion cells for battery storage systems, as well as on inputs for solar-panel glass manufacturing.
However, Vibhuti Garg, South Asia director for the Institute for Energy Economics and Financial Analysis, tells Carbon Brief that spending on wind energy and – “more critically” – on transmission and energy storage has either “stagnated or declined” this year.
Garg says grid infrastructure is “fundamental” to renewable expansion. She explains:
“Transmission infrastructure and storage are fundamental to integrating higher shares of renewable energy into the grid. As renewable penetration rises, these elements become not optional but indispensable, and the current level of support falls short of what is required.”
Adaptation
The budget does not announce any specific adaptation measures or schemes, although it does mention a plan to develop and rejuvenate reservoirs and water bodies and to “strengthen” fisheries value chains in coastal areas.
The budget does not mention or include measures related to heat stress or its impact on productivity and workers in sectors such as agriculture.
According to India’s national economic survey tabled ahead of the budget, adaptation and “resilience-related” domestic spending “surged” from 3.7% of the country’s GDP in 2016-17 to 5.6% in 2022-23.
Yet, unlike earlier budgets, allocations to and expenditure from India’s National Adaptation Fund for Climate Change are not separately visible in the 2026 document.
Harjeet Singh, climate adaptation expert and founding director at the Satat Sampada Climate Foundation, tells Carbon Brief that this budget was a “missed opportunity” and a response “not commensurate to the needs [for adaptation] on [the] ground or investment at the scale of crisis that we are facing”.
Singh adds that it fails to recognise the “huge” economic impacts already being felt in India. He says:
“If a budget doesn’t recognise how climate change is already eroding India’s development – causing huge economic losses – and is going to affect our GDP growth, it means that you aren’t really acting, or nudging states to do more.
“It was a missed opportunity to tell the world that we do see adaptation as a problem and we are acting on it, but we also need international cooperation.”

Five key climate and energy announcements in India’s budget for 2026
Months after a collapsed pipe pushed nearly 250 million gallons of raw sewage into the river, residents say the area still smells.
Members of a congressional subcommittee this week questioned utility leaders and state officials about their knowledge of preexisting problems with the sewage line that collapsed on Jan. 19 near the Potomac River.
Congress Grills Officials About the Potomac River Sewage Spill
A formal petition to the U.S. government calls for sanctions on Chinese seafood imports as it highlights China’s loophole-ridden illegal shark fin trade.
For migrant workers trapped onboard Chinese distant water fishing fleets, cutting the fins off sharks as they writhe violently on rusted decks in the Indian Ocean isn’t accidental. It’s an intentional and lucrative act that marks the start of a bloody half-a-billion-dollar offshore supply chain, tacitly supported by Beijing yet covertly concealed from port inspectors globally.
New data on international climate finance for 2023 and 2024 suggests that wealthy countries are highly unlikely to have met their pledge to double funding for adaptation in developing nations to around $40 billion a year by 2025 amid cuts to their overseas aid budgets.
At the COP26 climate summit in Glasgow in 2021, all countries agreed to “urge” developed nations to at least double their funding for adaptation in developing countries from 2019 levels of around $20 billion by 2025. Funding for adaptation has lagged behind money to help reduce emissions and remains the dark spot even as the data showed overall climate finance rose to a record $136.7 billion in 2024.
A United Nations Environment Programme report warned last year that wealthy nations were likely to miss the adaptation finance target and the data released on Thursday by the Organisation for Economic Co-operation and Development (OECD) shows that in 2024 adaptation finance was just under $35 billion.
The OECD, an intergovernmental policy forum for wealthy countries, said the increase between 2022 and 2024 was “modest”, adding that meeting the doubling target would require “strong growth” of close to 20% in 2025.
More cuts likely
The OECD’s figures do not go up to 2025, but several nations announced cuts to climate finance last year. The most notable was the abandonment of US pledges to international climate funds by the new Trump administration but the UK, France, Germany and other wealthy European countries also pared back their contributions.
Joe Thwaites, international finance director at the Natural Resources Defense Council, said developed countries were “not on track” to meet the adaptation funding goal.
Power Shift Africa director Mohamed Adow said adaptation finance is needed to expand flood defences, drought-resistant crops, early warning systems and resilient health services as the world warms, bringing more extreme weather and rising seas. “When that money fails to arrive, people lose homes, harvests and livelihoods – and in the worst cases, their lives,” he warned.
Imane Saidi, a senior researcher at the North Africa-based Imal Initiative, called the $35 billion in adaptation finance in 2024 “a drop in the ocean”, considering that the United Nations estimates the annual adaptation needs of developing countries at between $215 billion and $387 billion.

UK halves Green Climate Fund contribution, as it spends more on security
After promising £1.6 billion to the UN’s flagship climate fund in 2023, the UK government has now said it will only hand over half as much
If confirmed, a failure to meet the goal is likely to further strain relations between developed and developing countries within the UN climate process. A previous pledge to provide $100 billion a year of total climate finance by 2020 was only met two years late, a failure labelled “dismal” by the UAE’s COP28 President Sultan Al Jaber and many other Global South diplomats.
Missing that goal would also raise doubts about donor governments’ commitment to meeting their new post-2025 adaptation finance goal. At COP30 last year, governments agreed to urge developed countries to triple adaptation finance – without defining the baseline – by 2035.
African and other developing countries have pointed to lack of funding as a key flaw in ongoing attempts to set indicators to measure progress on adapting to climate change.
Speaking to climate ministers from around the world in Copenhagen on Wednesday, Turkish COP31 President Murat Kurum stressed the importance of climate finance. “It is easy to say we support global climate action,” he said, “but promises must be kept.”
He said the COP31 Presidency will use the new Global Implementation Accelerator and recommendations in the Baku-to-Belem roadmap, published last year, to scale up climate finance – and will hold donors accountable for their collective finance goals.
He noted that developed countries should this year submit their first reports showing how they will deliver their “fair share” of the new broader finance goal set at COP29 in 2024, to deliver $300 billion a year in climate finance by 2035. They are due to report on this once every two years.
Broader climate finance
The OECD data shows that the overall amount of climate finance – including funding for emissions cuts – provided by developed countries grew fast in 2023 before declining in 2024. In contrast, the amount of private finance developed countries say they “mobilised” increased in both 2023 and 2024, pushing the top-line figure to a record high.
While the OECD does not say which countries provided what amounts, data from the ODI Global think-tank suggests that the 2024 cuts to bilateral climate finance were spread broadly among wealthy nations.
Thwaites of NRDC welcomed the fact that overall climate finance provided and mobilised by developed countries exceeded $130 billion in both 2023 and 2024. He said that this was “well above earlier projections” and “shows that when rich countries work together, they can over-achieve on climate finance goals”.
But Sehr Raheja, programme officer at the Delhi-based Centre for Science and Environment, said these figures are “modest” when set against the new $300-billion goal.
“While the headline total figure of climate finance remains alright,” she said, “declining bilateral climate spending raises important questions about the predictability of high-quality, concessional public finance, which has consistently been a key demand of the Global South.”
She also lamented that loans continue to dominate public climate finance and that mobilised private finance is concentrated in middle-income countries and on emissions-reduction measures rather than adaptation projects. “Private capital continues to follow bankability rather than climate vulnerability or need,” she added.
Ritu Bharadwaj, climate finance and resilience researcher at the International Institute for Environment and Development, said the figures painted an outdated picture as climate finance has since declined as rich countries shrink their overseas aid budgets and increase spending on defence.
Last month, the OECD published figures showing that international aid – which includes climate finance – fell by nearly a quarter in 2025. The US was responsible for three-quarters of this decline. The OECD projects a further decline in 2026.
With Thursday’s climate finance report, the OECD is “publishing a victory lap for 2023 and 2024 at almost the same moment its own aid statistics show the funding base eroding underneath it,” Bharadwaj said.
