Labelling single businesses regarding their #climate solution is indeed a good way. Most important is the political framework and ultimately political will. Tackle the climate problem by the root will have a higher impact imho. #Market self-regulation might have limits 🤔

Analysis: India’s power-sector emissions flat for two years due to clean-energy surge - Carbon Brief

A surge in clean energy has kept carbon dioxide (CO2) emissions in check across India’s power sector, with no growth from the first half of 2024 to the same period in 2026.

Terminology matters: #DAC is only a capture process. We need to be precise in communication. What is meant? #CDR ( #DACCS) or #CCU ( #DACCU)? Or neither?

The most annoying part of being a researcher: Investing hours in adapting research proposals (for paying your own salary) to specific requirements and layouts of funders over and over again, so that a REVIEWER can kill it because he/she doesn‘t like it (w/o getting reviewer reports after rejection)🤦🏻‍♂️
