Environmental benefits

The Carlsbad Desalination Project will meet rigorous environmental standards set by state and local agencies, including the California Coastal Commission. By boosting the project’s energy efficiency, offsetting greenhouse gas emissions and enhancing coastal habitat, the project was designed with environmental stewardship in mind.

Poseidon’s Climate Action Plan calls for the plant to be net carbon neutral over 30 years by offsetting greenhouse gas emissions from project operations. It will be the first major California infrastructure project to offset its carbon footprint. This will be done through the purchase of carbon offsets and energy recovery technology at the desalination plant.

Energy recovery devices will save an estimated 116 million kilowatt-hours of energy per year, reducing CO2 emissions by 42,000 metric tons annually – roughly equivalent to the annual greenhouse gas emissions from 9,000 passenger vehicles.

Poseidon also is restoring 66 acres of wetlands in San Diego Bay.  The project involves excavating and grading a former salt production pond to create a mosaic of coastal habitats beneficial for a variety of fish and bird species.

In addition, Poseidon is preserving the 400-acre Agua Hedionda Lagoon by assuming responsibility for the continued stewardship of the lagoon.
