The latest deadline for countries to submit their nationally determined contributions (NDCs) under the Paris Agreement climate goals has passed, with only 15 of the 194 signatories complying. These plans outline how each country intends to limit global warming to 1.5°C above pre-industrial levels, ideally no more than 2°C. Despite the agreement’s intent to strengthen climate efforts every five years, the low submission rate highlights a concerning lack of urgency.
The February 2025 deadline was crucial ahead of COP30 in Brazil, where global climate negotiations will take place. Without updated NDCs, it becomes harder to pressure nations into stronger commitments and assess the financial resources needed for climate mitigation. While late submissions are still possible, the widespread failure to meet the deadline raises concerns about the future effectiveness of Paris Agreement climate goals.
Among the 15 nations that met the deadline were the UAE, UK, Switzerland, Ecuador, and smaller states such as Andorra and the Marshall Islands. Brazil, the host of COP30, pledged to cut emissions by 59-67% by 2035 compared to 2005 levels, increasing its previous targets. However, the country is not on track to meet its 2025 commitment, and its recalculated emissions baseline makes reductions appear larger than they are. Japan updated its pledge, targeting a 60% emissions reduction by 2035 and 73% by 2040, from 2013 levels. This represents how the ratchet system should work, with each commitment strengthening over time. The UK submitted an ambitious NDC to cut all greenhouse gas emissions by at least 81% by 2035, relative to 1990 levels. Independent scientists deemed this target “compatible” with limiting global warming to 1.5°C. The US, before former President Donald Trump withdrew from the Paris Agreement again, committed to reducing net emissions by 61-66% from 2005 levels by 2035. However, with the political uncertainty surrounding US climate policy, its long-term commitment remains questionable.
Major polluters, including China, India, and Russia, failed to submit updated NDCs. India’s past pledges, including a 35% reduction in emissions by 2030 from 2005 levels, have been labeled “insufficient” by climate analysts. Its latest national budget lacked significant funding for climate adaptation. China, which previously committed to lowering CO₂ emissions by 65% by 2030, has been responsible for 90% of the world’s emissions growth since the Paris Agreement climate goals were established. US-China climate talks stalled in 2022 amid rising economic competition, leading to trade barriers that slow the adoption of green technology. Russia’s initial NDCs were deemed “critically insufficient,” and subsequent updates have failed to strengthen commitments. Instead, the country is ramping up fossil fuel extraction, including Arctic oil drilling.
The absence of commitments from major economies suggests a shift away from global climate cooperation. Instead, geopolitical interests are influencing environmental strategies, with countries prioritizing control over critical minerals essential for green technologies. Scientists warn that if nations continue to delay or weaken their NDCs, global warming could reach a catastrophic 4.4°C by 2100. In contrast, meeting the Paris Agreement climate goals through international collaboration and green investment could limit warming to 1.8°C. The choices made today will determine the trajectory of climate change for decades to come.
