With governments due to announce ambitious emissions reduction targets at a UN summit in New York this week, the UN climate chief warned on Monday they will not add up to what is needed to keep global warming to the limits in the Paris Agreement.
Countries were asked by the UN climate change body to publish their new national climate plans (NDCs) by the end of September, in time to be included in a key summary report next month comparing those pledges with the global cuts scientists say are needed.
With around 110 countries lined up to speak at UN headquarters on Wednesday, a clearer picture will start to emerge on the scale of the gap between emissions-cutting targets and the reductions in planet-heating gases required to meet the 1.5C warming limit – 43% below 2019 levels by 2030 and 60% by 2035.
The European Union was unable to meet the September deadline because of political differences and will only present a range described as a “statement of intent” in New York this week.
China, meanwhile, is not expected to deliver an NDC that would align its efforts with the 1.5C limit. Heads of state from India and Indonesia are not scheduled to participate in the New York summit and so are likely to announce their plans later.
“We know [the NDCs] are going to be softer than what science dictates,” the UN’s climate head Simon Stiell told the opening of Climate Week in New York.
At the COP30 climate negotiations in Brazil in November, he added, “the focus… will not be what countries have presented, but how will they respond to those submissions – and that primary response is about accelerating implementation [of the NDCs], just getting it done.”
Complex process delivering results
Despite the expected emissions gap, growing criticism of the UN climate process, and rising global temperatures, Stiell maintained that the 2015 Paris Agreement is working to curb global warming. Projections before it was adopted suggesting a 5C rise are now down to around 3C.
“It is slower than science dictates. It is a very, very complex process, but it is delivering results,” he said. His agency’s upcoming report will show how much further warming estimates can be lowered towards the 1.5C goal, he added.
“We won’t be at 1.5 but we… will have inched forward, so progress is being made,” he added.

Speaking alongside COP30 president André Corrêa do Lago, both men called for more effort to translate the decisions made by the UN process into stronger climate action in the world outside. For that to happen, they said, the benefits need to be communicated more clearly to the wider public.
“What I believe is important is for people to have confidence in the process,” Corrêa do Lago said. “We have to show that there are solutions, and we have to show that it is economically intelligent logic and useful to fight climate change – for jobs, for development. And I think this message is not fully perceived.”
The veteran Brazilian diplomat added that he hoped the “action agenda” at COP30, which aims to encourage businesses, cities and citizens to ramp up action on climate change, would make the mission more popular.
Stiell agreed, saying one key challenge is to “dejargonise” the COP negotiations, which are notoriously hard for those on the outside to understand, because of their long texts laden with difficult language and fractious discussions. “It is making what we’re doing more consumable in living rooms,” he said.
Spreading the renewable energy boom
In a separate speech on Monday afternoon, the UN climate chief said that, despite the negative “noise”, “the facts show a world aligning with the Paris Agreement”.
He emphasised how investment in renewable energy has increased ten-fold in the past 10 years, with investment in clean energy hitting $2 trillion last year alone and more than 90% of new renewables now costing less than the cheapest new fossil fuel option.
“But this boom is uneven. Its vast benefits are not shared by all,” he added. “Meanwhile, climate disasters are hitting every economy and society harder each year.”
Stiell called on industry to step up its efforts to decarbonise, saying the transition would lead to “stronger economies, more resilient supply chains, lower costs and lower emissions”.

In particular, he urged companies running artificial intelligence (AI) platforms to “power it with renewables, and innovate to drive energy efficiency”. He warned of the need to “blunt its dangerous edges” and to use its power “to drive real-world outcomes: managing microgrids, mapping climate risk, guiding resilient planning”.
Speaking separately at the Climate Week opening, Mark Patel, a senior partner at McKinsey & Company, said the urgency to scale up AI – which is set for investment of $5.2 trillion by the end of the decade – is currently reigniting demand for fossil fuels and competing for natural resources.
But, he added, it could instead be used to drive accelerated uptake of renewables and cheap battery storage, as well as nuclear energy and more efficient semiconductors.
Stiell argued that if the real economy powers forward with climate solutions and the UN talks set a higher bar for that action, with both feeding through to the other, it could lead to “a kind of virtuous loop”.

Why women’s leadership is central to unlocking the global phaseout of fossil fuels
Osprey Orielle Lake is founder and executive director of The Women’s Earth and Climate Action Network (WECAN) and a steering committee member of the Fossil Fuel Treaty.
Around the world, women are leading some of the most powerful efforts to stop fossil fuel expansion and implement the just transition the climate crisis demands.
In the Ecuadorian Amazon, Nemonte Nenquimo, an Indigenous Waorani woman, led a successful lawsuit for the Waorani against the Ecuadorian government to protect their territory and the Amazonian rainforest from oil extraction. Ecuador’s courts ruled in favor of the Waorani, setting a legal precedent for Indigenous rights and prompting similar legal fights worldwide.
In the heart of Cancer Alley in the Gulf South of the United States, Sharon Lavigne, founder of Rise St. James, took on fossil fuel polluters and won. After stopping a Formosa petrochemical facility in her parish, she continues to organize communities to stop fossil fuels, bringing awareness to the severe health impacts caused by the industry.
An initial cornerstone for an upcoming government convening on fossil fuel phaseout is the Fossil Fuel Treaty, which was founded by Tzeporah Burman. She won the 2019 Climate Breakthrough Award for her bold Treaty vision, which has now taken center stage in international climate action.
These women are not anomalies, they are part of a broader movement. Women the world over are stopping harmful projects and building regenerative futures. They are defending land, water, climate, and health. They are redefining what leadership looks like in a time of crisis.
Research has found that countries with higher representation of women in parliament are more likely to ratify environmental treaties. One prominent cross-national study found that CO2 emissions decrease by approximately 11.51 percent in response to a one-unit increase in each countries’ scoring on the Women’s Political Empowerment Index. When women are incorporated into disaster planning or forest management, projects are more resilient and effective.
Yet because of persistent gender inequality, women – particularly Indigenous, Black and Brown women and women in low-income and frontline communities – are often disproportionately harmed by fossil fuel extraction and pollution. At the same time, they are also indispensable leaders of equitable solutions.
Bold, transformative solutions needed
Although the climate crisis may not be in the headlines recently, the crisis is increasing at lightening speed. From 2023 to 2025, the world crossed a dangerous threshold, marking the first three-year global average that exceeded the crucial 1.5°C guardrail, the very limit scientists identified as critical to avoid the worst catastrophic tipping points.
This is not a eulogy for 1.5°C, but an alarm about a narrowing window. The data makes clear that we still have an opportunity to hold long-term warming below that life-affirming threshold. What is required now is not incrementalism and business as usual but bold and transformative solutions from grassroots movements to the halls of government.


At the top of the list in tackling the climate crisis is the urgent need for a global phaseout of fossil fuel extraction and production. Coal, oil, and gas remain the primary driver of the climate crisis, and fossil fuel pollution is responsible for one in five deaths worldwide. The simple but challenging fact is, there is no way forward without a phaseout.
In 2023, at the U.N. Climate Summit in Dubai (COP28), governments agreed for the first time to “transition away from fossil fuels.” The language was historic but nonbinding, and implementation has been severely hindered. Most governments are doubling down and increasing production across coal, gas, and oil. At COP30 in Brazil, while 80 countries called for fossil fuel language in the final outcome text, governments ultimately left without any commitments to a phaseout.
Women’s assembly for fossil fuel phaseout
In response to this stalled progress, Colombia and the Netherlands are convening the First Conference on Transitioning Away from Fossil Fuels, bringing together governments committed to advancing cooperation toward a managed, equitable phaseout. Occurring outside the formal UN climate negotiations, the gathering reflects a growing recognition that progress often requires voluntary alliances of ambitious nations.
The urgency of this moment demands more than policy tweaks. It calls for a restructuring of the systems that fueled the crisis such as economic models that externalize harm, energy systems that prioritize profit over people, and governance structures that marginalize frontline communities. How we navigate this transition will shape the world our children inherit, and evidence shows that women’s leadership is vital to ensure a healthy and equitable outcome.
Colombia aims to launch fossil fuel transition platform at first global conference
As governments, civil society and global advocates prepare for the conference in Colombia, women’s leadership must not be an afterthought. It needs to be central to the agenda, inspired by equity, justice and care.
That is why the Women’s Earth and Climate Action Network is convening global women leaders to advance strategies, proposals, and projects at the public Women’s Assembly for a Just Fossil Fuel Phaseout to be held virtually on March 31 to call for transformative action in Colombia. All are welcome.
A livable future depends on bold action now, and on women leading the way at this critical moment.

On the Farm, the Hidden Climate Cost of America’s Broken Health Care System
American farmers are drowning in health insurance costs, while their German counterparts never worry about medical bills. The difference may help determine which country’s small farms are better prepared for a changing climate.
Samantha Kemnah looked out the foggy window of her home in New Berlin, New York, at the 150-acre dairy farm she and her husband, Chris, bought last year. This winter, an unprecedented cold front brought snowstorms and ice to the region.
