San Francisco set new, more ambitious climate change goals Tuesday, including getting to net zero greenhouse gas emissions produced in the city by 2040, as wildfires, drought and heat waves worsened by climate change plague California and floods in Europe grab headlines.

The Board of Supervisors unanimously approved an update to the environment code that pledges the city will cut its greenhouse gas emissions to at least 61% below 1990 levels by 2030. The city wants to reduce emissions generated outside city borders for products consumed in San Francisco – such as the carbon footprint of SFO air travel – by 40% by 2030 and 80% by 2050.
