- July 2025 science

- January 2023 market
The voluntary carbon market integrity crisis deepens.
A joint Guardian and Die Zeit investigation into Verra-issued REDD+ credits found that a large proportion were of doubtful integrity. Confidence in voluntary carbon collapsed almost overnight. The episode that the nature market is now trying very hard not to repeat.
