Oceans & Coasts

"The ocean has absorbed 90% of the heat we've added. Time to give it back."

Oceans regulate climate, feed 3 billion people and shelter coasts from storms. Warming, acidification and overfishing are dismantling marine food webs — but marine protected areas and blue-carbon ecosystems recover fast when we let them.

Living shorelines — mangroves, seagrass, reefs — protect >1B people.

Levers that move the needle

Protect

Ratify the High Seas Treaty

Legal framework for MPAs beyond national waters — unlocks 60% of the ocean.

Restore

Blue-carbon ecosystems

Mangroves store carbon 4× faster per hectare than tropical forests.

Reduce

Cut single-use plastic

11M tonnes reach oceans each year — most from land.

Advocate

Ban destructive fishing

Bottom trawling emits ~1Gt CO₂ per year — comparable to aviation.

Signals of progress

  • High Seas Treaty adopted (2023)
  • Mangrove loss slowed 44% globally

Warning lights

  • 4th global coral bleaching event underway
  • Ocean heatwaves at record duration
