Deep dives

Impact of U.S. Withdrawal from Climate Agreements

The U.S. has announced its withdrawal from the Paris Climate Agreement and the World Health Organization, actions that could significantly impact global climate initiatives. Critics highlight that the U.S., being the second-largest emitter of greenhouse gases, will likely reduce its influence in international climate negotiations, potentially allowing other countries to lessen their commitments to emission cuts. The withdrawal not only affects diplomatic leverage but also eliminates critical funding for climate finance, which supports low-income nations in combating climate change. Nevertheless, a majority of global emissions are still attributable to countries remaining in the Paris Agreement, suggesting that international climate efforts can still proceed despite the U.S. exit.
