Lessons From California’s Carbon Dioxide Removal Policies

"...The California Climate Crisis Act, or AB 1279, was signed into law in September of 2022, and requires net-zero greenhouse gas emission by 2045 and net-negative emissions thereafter. It mandates at least 85% emissions reductions from 1990 levels by 2045, ensuring that carbon dioxide removal does not play an excessive role in meeting net zero..."

'Climate breakdown' alert as air quality dips during heatwaves: UN chief

"...The 2023 WMO Air Quality and Climate Bulletin – coming on the heels of the Secretary General’s statement – puts the spotlight firmly on the damage caused by heatwaves. It notes that high temperatures are not only a hazard by themselves, but they also trigger damaging pollution. Based on the 2022 data, the report shows how heatwaves fanned a dangerous drop in air quality last year..."


Blog: Update on Site-Specific Air Standard Approval – Glencore Canada Corporation

"...In June 2023, CELA made a submission to the Ontario government regarding Glencore Canada Corporation’s (Glencore) application for a site-specific air pollution standard (SSS) for its Kidd Concentrator facility. Glencore’s application, if approved, would allow them to release sulphur dioxide at a rate almost 7 times the health-based provincial air standards. This risks poor air quality with potentially serious consequences to the environment and human health..."
