A $300 billion annual climate finance deal adopted at COP29 in Baku has been met with sharp criticism from developing nations, who argue that the plan fails to address the urgent and growing impacts of climate change.

Indian representative Chandni Raina criticized the agreement, stating:
“I regret to say that this document is nothing more than an optical illusion. This, in our opinion, will not address the enormity of the challenge we all face. Therefore, we oppose the adoption of this document.”

The deal, finalized after extended negotiations, aims to provide $300 billion per year by 2035 to support vulnerable countries. While this marks an increase from the $100 billion annual target set in 2009, it falls short of the broader $1.3 trillion goal that includes contributions from public and private sources.

UN climate chief Simon Stiell acknowledged the deal as a step forward but emphasized the need for accountability:
“This deal will keep the clean energy boom growing and protect billions of lives. But like any insurance policy, it only works if the premiums are paid in full, and on time.”

Tina Stege, climate envoy for the Marshall Islands, called the agreement inadequate:
“We are leaving with a small portion of the funding climate-vulnerable countries urgently need. It isn’t nearly enough, but it’s a start.”

The summit highlighted the growing divide between wealthy and developing nations. U.S. climate adviser John Podesta commented on the resistance to bolder initiatives:
“There’s definitely a challenge in getting greater ambition when you’re negotiating with the Saudis.”

The $300 billion target also comes amid doubts about the U.S. commitment, as former President Donald Trump’s recent election win raises concerns about future climate funding. Trump has pledged to remove the U.S. from international climate agreements, calling climate change a “hoax.”

President Joe Biden, however, hailed the agreement as a significant step, while urging further action:
“Today’s outcome puts us one significant step closer. On behalf of the American people and future generations, we must continue to accelerate our work to keep a cleaner, safer, healthier planet within our grasp.”

With extreme weather events escalating globally, the stakes remain high. UN reports indicate the world is on track for up to 3.1°C of warming by the century's end, far beyond the 1.5°C Paris Agreement target.

Negotiators will face further challenges next year at COP30 in Brazil, where they must outline actionable steps to meet these climate finance and mitigation goals.
