Global Climate Commitments: The Urgent Push Ahead of COP30
As the 30th Conference of the Parties to the United Nations Framework Convention on Climate Change (COP30) looms on the horizon, the city of Belém, Brazil prepares to host critical discussions. Here, at the confluence of the Amazon River and the Atlantic Ocean, global leaders are tasked with advancing the objectives set forth by the Paris Agreement.
The Paris Agreement, inked in 2015, revolves around nationally determined contributions (NDCs), which are voluntary pledges detailing each country’s climate goals. These NDCs are meant to be updated every five years, aiming for the highest ambition, and they should evolve over time through a “ratchet mechanism” informed by global stocktakes. Collectively, they strive to limit global temperature rise to 1.5°C above pre-industrial levels. However, current projections suggest a pathway to 2.6°C of warming, posing significant risks.
This year is crucial for NDCs as countries are expected to submit their updated commitments, known as NDCs 3.0, building on previous submissions in 2015 and 2020. These new pledges respond to the first global stocktake concluded in 2023 and set goals for 2035. Notably, 2035 is also the deadline for the New Collective Quantified Goal on Climate Finance (NCQG) and is the year by which the Intergovernmental Panel on Climate Change (IPCC) suggests a 60% reduction in global greenhouse gases from 2019 levels is needed to stay within the 1.5°C target.
Despite deadlines in February and then September, many countries lag in submitting their NDCs. Anticipation was high at September’s UN General Assembly and the secretary-general’s Climate Summit for new climate commitments, especially from major emitters. The outcomes, however, left many observers disappointed due to the limited number of announcements and their lackluster ambition.
NDCs 3.0: A Cut Below Expectations
Although more than 150 leaders discussed climate change at the General Debate, and around 35 attended the Climate Summit, the number of NDC submissions was underwhelming. By September 16, 2025, only 35 new NDCs were submitted, covering about 21% of global GHG emissions. This included contributions from 11 developed countries and five G20 nations: the UK, the US, Canada, Japan, and Brazil. By October 17, that number increased to 62, including Australia, Nigeria, Pakistan, Russia, Iceland, and Ethiopia, bringing the G20 count to six, yet still covering only about 30% of global emissions.
China’s pledge drew significant attention due to its substantial share of global emissions—30.1%—and its crucial role in climate change mitigation. President Xi Jinping’s announcement of a 7–10% reduction in GHGs by 2035 was criticized for falling short of the 30% reduction civil society organizations deemed necessary to meet the 1.5°C goal. Despite this, China’s influence is pivotal, given its industrial capacity and renewable energy advancements.
Other nations made notable declarations at the summit. Brazil reaffirmed its target of a 59–67% reduction in emissions, the UK pledged an 81% reduction from 1990 levels, and the EU proposed increasing its goal to 66–72% pending approval. Meanwhile, Australia, Norway, and Russia outlined their respective reduction commitments, and several other countries indicated progress on their next NDCs.
The overall reaction from civil society was one of concern, noting the insufficient number of NDCs submitted, the perceived inadequacy of China’s targets, and the lack of detail from crucial mid-level emitters like India and Indonesia. The upcoming NDC Synthesis Report is expected to reflect that current pledges still place the world above the 2.0°C warming threshold. The absence of US participation under President Donald Trump further underscored the global disengagement, contrasting with President Xi’s involvement, albeit remotely.
Urgent Call to Action
To realign with the Paris Agreement targets, countries must not only submit NDCs but increase their ambitions. The 2015 Paris Agreement aimed to keep temperature increases “well below 2°C” while aspiring for 1.5°C. Recent science emphasizes the critical importance of the latter goal, championed by small island states and vulnerable countries.
Recent developments, including an advisory opinion from the International Court of Justice, underscore the legal imperative for states to align with the 1.5°C target, highlighting the urgency of ambitious NDCs 3.0.
China’s role remains crucial, and past trends suggest it might exceed its modest targets, particularly given its renewable energy leadership. President Xi’s mention of expanding solar and wind capacity to 3,600 gigawatts highlights potential for major coal reductions.
The Climate Summit also highlighted methane reduction as a priority, as noted by the secretary-general. Reducing methane from fossil fuels could see significant gains at minimal cost.
However, achieving these targets requires substantial financial investment, with trillions needed by 2030—far exceeding current NCQG allocations. Without ample funding, even ambitious NDCs will fall short of the 1.5°C goal.
With COP30 nearing, the pressure mounts for decisive action to secure a sustainable future.
