Ozone Protection: Mexico says it has eliminated 88% of its baseline consumption of ozone-depleting HCFCs and is aiming for a full phaseout by 2030. Import controls and cleaner refrigeration technologies are also part of its effort to reduce high-warming HFCs. Cross-Border Pollution: Mexico’s ambassador to the U.S. says securing infrastructure funding to tackle the Tijuana River sewage crisis is a binational priority. Recent research found the pollution can travel underwater to La Jolla and become airborne. Clean Air: Baja California has launched a winter campaign to curb pollution spikes in Mexicali, where temperature inversions can trap vehicle exhaust, dust and other pollutants near the ground. Maya Forest: More than 3,500 acres have been added to Belize’s Maya Forest Corridor, linking protected areas and strengthening a conservation network shared across the region. Maya Heritage: Reports of mercury contamination at ancient Maya sites raise concerns about pollution in two lakes and its long-term effects. Monarch Migration: Tiny solar-powered trackers are helping scientists map monarch butterflies’ routes to their winter forests in central Mexico, knowledge that could support conservation as habitat loss, pesticides and climate change threaten the species.
