If Mayor London Breed has her way, San Francisco's buildings will be carbon neutral by the year 2050. She wants the city to be a global climate leader, and on Wednesday she announced an ambitious plan to get there.
Besides carbon-neutral buildings, the new plan includes halving landfill waste, financing green infrastructure and transitioning the city to 100 percent renewable electricity generation by 2030.
Breed has made the environment a priority in the early days of her administration.
"We here in San Francisco acknowledge that climate change is real, it poses a very serious threat, and we need to act yesterday," she said.
Breed's announcement comes ahead of next week's Global Climate Action Summit, hosted by Gov. Jerry Brown. The San Francisco summit will bring in leaders from around the world to talk about the work that cities and states can do to fight climate change.
