Project Cosmos launch, science under attack at Bonn, and emissions inequality: Carbon Brief's daily roundup for June 23 2026

Carbon Brief's daily roundup for June 23, 2026, covers three major stories. Project Cosmos, a new climate monitoring initiative, has launched. At the Bonn climate talks, scientists report that climate science is facing political attacks, raising concerns about the integrity of the negotiation process. A new analysis on emissions inequality shows that the richest 1% of the global population emits more carbon than the poorest 50% combined. These stories highlight the ongoing tension between climate ambition and political reality. The Project Cosmos launch could improve data for carbon markets and policy. The attacks on science at Bonn threaten to undermine the evidence base for emissions reduction targets. The emissions inequality data underscores the need for fair burden-sharing in climate finance and carbon pricing mechanisms. For anyone tracking carbon markets, UN climate negotiations, or emissions policy, this roundup provides a concise snapshot of the day's key developments.
