WESTCARB is a collaborative research project bringing together dedicated scientists and engineers at 70 public agencies, private companies, and nonprofits to identify and validate the best regional opportunities for keeping CO₂ out of the atmosphere and thereby reducing mankind's impact on the climate.

Established in Fall 2003, WESTCARB is one of seven research partnerships co-funded by the U.S. Department of Energy to characterize regional carbon sequestration opportunities and conduct technology validation field tests. The California Energy Commission manages WESTCARB, is a major co-funder, and hosts and maintains this website. See the About WESTCARB page for more.
