Consistent with the scientific community’s recommendations to reduce emissions by 80% to stabilize our climate system, San Francisco has adopted these emission reduction goals:

  • 25% reduction below 1990 levels by 2017
  • 40% reduction below 1990 levels by 2025
  • 80% reduction below 1990 levels by 2050

Achieving these reductions requires us to change our energy sources, our transportation choices and make other healthy choices in our daily lives.
