COMPANY DESCRIPTION

CalBio projects benefit the environment both globally and locally. Working with the dairies we capture methane, a potent greenhouse gas, that currently is released into the atmosphere and use it beneficially. Our projects reduce CO2e emissions by over one million metric tons per year, and we are on track to double these CO2e reductions over the next three years.

One of the major uses of CalBio biomethane will be as vehicle fuel. When truck fleets convert from diesel to natural gas, pollution emissions are reduced by approximately 90%, a great and immediate advancement for air quality in California’s San Joaquin Valley and L.A. basin.
