China's 2020 desalination plans could cause emissions surge
China's 2020 ambition to produce drinking water at 3 million m³day from desalination threatens to increase carbon emissions through increased use of largely coal-fired power generation according to the World Resources Institute (WRI). The institute said the energy penalty could be offset by some 75% by greater use of water reuse.

Carlsbad project plan for green SWRO
The largest and most advanced seawater desalination project under development in the USA today is the 189,000 m³/d plant in Carlsbad in southern California. This project is collocated with the Encina coastal power generation station, which currently uses seawater for once-through cooling. The Carlsbad seawater desalination project is developed as a public-private partnership between Poseidon Resources and eight utilities and municipalities in San Diego County. Greenhouse gas (GHG) emissions associated with production of desalinated seawater at the Carlsbad project are planned to be mitigated by a portfolio of alternative technologies and measures: from the use of CO2 for water production, green building design and of state-of-the-art technology; to the development of on-site and off-site green energy projects and CO2 sequestration by reforestation and new coastal wetlands. The mix of GHG reduction alternatives will be prioritized and implemented under a Carbon Action Plan which defines a roadmap for carbon-neutral seawater desalination.
