Los Angeles Mayor Eric Garcetti on Wednesday announced an ambitious plan to make the city more environmentally sustainable and to create 15,000 more “green” jobs by 2017.

The policy roadmap sets out short and long-term targets in 14 categories related to the environment and the economy. On the economic front, Garcetti seeks to create a total of 20,000 green jobs by mid-2017, the end of his mayoral term. As of December 2014, about 4,700 green jobs had been created, mostly in rooftop solar panel installations, lawn removal and waste recycling.

Garcetti is also calling for 100,000 new housing units to be built by 2021 and to ensure that at least 57 percent of new housing units are built within 1,500 feet of transit stops by 2025.

On the environmental front, Garcetti aims to reduce per capita water use 20 percent by 2017, triple rooftop solar energy production by 2017 and cut greenhouse gas emissions 80 percent from 1990 levels by 2050.

Garcetti has directed Matt Petersen, his sustainability officer, to work with city departments to map out how they intend to achieve the goals outlined in the plan. Some elements of the plan may need City Council approval. Some of the funding will come from the city’s General Fund, but many elements of Garcetti’s plan will need additional funding sources.
