Rich countries have pledged to contribute $300bn a year by 2035 to help poorer nations combat the effects of climate change after two weeks of intense negotiations at the United Nations climate summit (COP29) in Azerbaijan’s capital, Baku.While this marks a significant increase from the previous $100bn pledge, the deal has been sharply criticised by developing nations as woefully insufficient to address the scale of the climate crisis.This year’s summit, hosted by the oil and gas-rich former Soviet republic, unfolded against the backdrop of a looming political shift in the United States as a climate-sceptic Donald Trump administration takes office in January. Faced with this uncertainty, many countries deemed the failure to secure a new financial agreement in Baku an unacceptable risk.Here are the key takeaways from this year’s summit:‘No real money on the table’: $300bn climate finance fund slammedWhile a broader target of $1.3 trillion annually by 2035 was adopted, only $300bn annually was designated for grants and low-interest loans from developed nations to aid the developing world in transitioning to low-carbon economies and preparing for climate change effects.Under the deal, the majority of the funding is expected to come from private investment and alternative sources, such as proposed levies on fossil fuels and frequent flyers – which remain under discussion.“The rich world staged a great escape in Baku,” said Mohamed Adow, the Kenyan director of Power Shift Africa, a think tank.“With no real money on the table, and vague and unaccountable promises of funds to be mobilised, they are trying to shirk their climate finance obligations,” he added, explaining that “poor countries needed to see clear, grant-based, climate finance” which “was sorely lacking”.The deal states that developed nations would be “taking the lead” in providing the $300bn – implying that others could join.The US and the European Union want newly wealthy emerging economies like China – currently the world’s largest emitter – to chip in. But the deal only “encourages” emerging economies to make voluntary contributions.Failure to explicitly repeat the call for a transition away from fossil fuelsA call to “transition away” from coal, oil, and gas made during last year’s COP28 summit in Dubai, the United Arab Emirates, was touted as groundbreaking – the first time that 200 countries, including top oil and gas producers like Saudi Arabia and the US, acknowledged the need to phase down fossil fuels. But the latest talks only referred to the Dubai deal, without explicitly repeating the call for a transition away from fossil fuels.Azerbaijan’s President Ilham Aliyev referred to fossil fuel resources as a “gift from God” during his keynote opening speech.New carbon credit trading rules approvedNew rules allowing wealthy, high-emission countries to buy carbon-cutting “offsets” from developing nations were approved this
