LA County Sanitation Districts Reaches Carbon Neutrality
The Los Angeles County Sanitation Districts, which manages wastewater and solid waste for over half the residents in Los Angeles county, announced that its operations result in a net reduction of GHG into the environment. A third party reviewed and verified the Districts' 2021 emissions inventory.
"Our mission is to convert waste into resources. For decades, we and our partners have undertaken activities that reduce greenhouse gas emissions. For example, by converting sewage into recycled water, we reduce the need to import water, the energy used to import water and the greenhouse gas emissions used to create energy," said Robert C. Ferrante, Chief Engineer and General Manager for the Sanitation Districts in a statement. "We're proud to have exceeded carbon neutrality in 2021 and are looking for more ways to reduce regional greenhouse gas emissions."
The Sanitation Districts recently published a document called "Reducing Our Carbon Footprint: The Sanitation Districts' Greenhouse Gas Reduction Initiatives" that describes the agency's seven biggest initiatives that reduce GHG emissions. Most of these initiatives produce green power, which reduces the use of fossil fuels, a main contributor to global greenhouse gas emissions.
The biogas created at the agency's landfills and wastewater treatment plants is converted into enough electricity to meet the needs of 23,000 homes. Other initiatives include converting food waste into vehicle fuel, commodities recycling, water recycling, using alternatives to fossil fuel in vehicles, biosolids management and green waste management. Collectively, these initiatives avoided 362,000 metric tons of carbon dioxide equivalents.
