In what environmental leaders are calling "the most significant climate agreement since Paris," representatives from 150 nations gathered in Stockholm to sign a binding accord committing to carbon neutrality by 2040 — a full decade ahead of previous targets.

The Stockholm Climate Compact includes enforceable emissions reduction milestones, a $500 billion global green technology fund, and penalties for non-compliance. Developing nations will receive substantial financial support to transition their energy infrastructure.

"We no longer have the luxury of incremental change," declared UN Secretary-General at the signing ceremony. "This accord represents the political will that scientists have been demanding for decades."
