L.A. assessed its community-wide greenhouse gas (GHG) emissions for 2013-2016 following the Global Protocol for Community-Scale Greenhouse Gas Inventories (GPC), an internationally recognized GHG accounting and reporting standard for cities. The inventory covers emissions from the energy, transportation, and waste sectors.
In 2016 alone, city-wide GHG emissions decreased 11%, which is equivalent to taking 737,000 cars off the road. At the same time, L.A.’s population continues to increase and our economy continues to grow. Our per capita emissions are currently 6.7 metric tons CO2e – about one-third of the national average – and are on track with the goals for cities to achieve the Paris Agreement.
Much of the decline in emissions in the last year was due to the Los Angeles Department of Water and Power’s (LADWP) increasingly cleaner energy mix. From 2015 to 2016, LADWP decreased the percentage of its coal-generated electricity from 37% to 19% and increased renewables from 21% to 29%.
Notably, L.A. experienced a drop in emissions from energy used to move and provide water to Angelenos. From 2015 to 2016, these emissions declined by 29%. Although emissions related to water consumption make up a small percentage of total community-wide GHGs (0.7%), they are important to monitor as we transform our water system and move towards water independence.
