COP26 came with a lot of expectations. One could believe that this event would solve climate change with one meeting. The Conference of Parties is not about making large, global decisions, it’s about agreeing on the practical implementation of the Paris Agreement between 198 countries. And despite the many disappointments, the COP has delivered one key aspect: a global commitment to reporting, and transparency on a regular basis. Never before have the majority of UN members agreed to report on their environmental impact, every two years, beginning in 2024.
