The world’s largest fossil fuel and cement companies should shoulder a major share of the investment needed to develop carbon removal technologies, according to a new peer-reviewed study in @climate-policy.bsky.social. #carbonmajors #CDR #climatepolicy
The responsibility of investor-owned carbon majors to contribute to direct air carbon capture and storage investment
Carbon dioxide removal (CDR) options are critical for achieving global climate objectives. Yet, many proposed removal technologies are in their formative phase. Significant near-term investments ar...

New research shows that near-term mitigation could spare future generations around 0.6 meters of sea-level rise caused by emissions between 2020 and 2090, making today’s decisions critical not only for limiting warming but also for coastal impacts.

German court has established that energy companies can be held liable for climate change damages.
Given those damages are in the 10s of trillions of USD, this is potentially a massive deal. Huge liabilities for historic polluters as more cases get established.
