City and state leaders representing more than 60% of US GDP on Thursday pledged
at COP31 in Antalya to work with the United Nations to track US greenhouse gas
emissions. The initiative is intended to demonstrate ongoing subnational
decarbonization despite the Trump administration's withdrawal from the Paris
Agreement and regulatory rollbacks on emissions. United Nations
Secretary‑General Guterres welcomed the local action, citing rising
private‑sector investment in renewables and increasing commitment from governors
and mayors, and said he hoped the US as a whole would reengage.
