It’s been 30 years since the first COP talks, and many are wondering if they really make a difference. This year, around 40,000 attendees are heading to Belém, Brazil, to take part in COP30, the same country that held the historic Rio Earth Summit in 1992. Back then, it was hailed as a major turning point for global climate action, bringing together leaders to create the UNFCCC, the world’s first global climate treaty.
Michael Howard, the former UK environment secretary, recalled the optimism in 1992. “It felt like the start of something important,” he said. Sadly, after 29 COPs, the situation is dire. Greenhouse gas emissions have risen by 65% since 1990, and CO2 levels are climbing faster than ever.
In 2015, leaders reached the Paris Agreement, aiming to limit global warming to 1.5°C. Yet today, we are already nearly at 1.4°C. Ban Ki-moon, former UN Secretary-General, acknowledged the initial success of the Agreement but pointed out unequal commitments from countries since then. While some nations have taken action, others have lagged behind.
Climate change is intensifying extreme weather events. For example, just weeks before COP30, Hurricane Melissa struck the Caribbean, causing severe damage. BloombergNEF reported that global climate-related damage hit £1 trillion in 2024, mainly due to increasingly severe events.
However, not all news is bleak. The COP talks have, indeed, led to progress. Before the Paris Agreement, projections suggested warming could reach 4°C. Thanks to global efforts, that estimate has improved to around 2.8°C. This still poses grave risks, like the potential collapse of significant rainforest regions.
The shift towards renewable energy is also promising; for the first time, renewables provided more electricity than coal this year. Additionally, countries are increasingly setting net-zero targets, covering about 77% of the global economy.
Ed Miliband, the UK’s Energy Secretary, emphasized the importance of global cooperation. “You can’t tackle climate change alone,” he said. While deforestation is slowing, we still emit too much carbon compared to our economic growth.
Ian Hall, a climate professor at Cardiff University, pointed out that the progress made is insufficient relative to the urgency of the situation. He warned that if we reach an increase of 2.8°C, we could see catastrophic impacts, including the melting of major ice sheets and mass migrations from increasingly uninhabitable areas.
Some critics argue that the COP process is losing its effectiveness. A letter signed by climate experts in 2022 claimed that the summits have become too influenced by fossil fuel interests, slowing progress and complicating discussions. Johan Rockstrom, a prominent climate scientist, believes it’s time to shift from lofty goals to accountability, highlighting delivered promises instead.
Dr. Jennifer Allan, an environmental politics expert, now feels that the hope placed in COPs may be misplaced, especially given their large carbon footprint. Meanwhile, UN climate chief Simon Stiell is looking to reform the COP process while keeping all nations involved.
The COPs were designed during a calmer period in the 1990s. Today, with 184 global conflicts compared to 118 back then, establishing unity is challenging. Climate impacts are hitting hard and becoming increasingly costly. This raises questions about whether countries can still work together effectively.
Many of the countries most affected by climate change continue to support the COP process. They value having a voice alongside major economies. For instance, Palau’s President, Surangel Whipps Jr., spoke on the importance of attending these summits to advocate for vulnerable nations, mentioning how pressure from COP discussions led Australia to increase their emissions-reduction targets.
Despite the skepticism, the participation of so many nations in COP30 may signal that multilateral efforts are still alive. As attention shifts to finding actionable solutions, the stakes for our planet have never been higher.
