Green-e Climate certified carbon offsets include reductions from the following projects:

Green Valley Dairy
Project Location: Krakow, Wisconsin
Online Date: February 15, 2006
Endorsed Program: Climate Action Reserve
Type of Facility: Livestock Methane Capture

Your participation supports projects from dairy farms in communities across the United States that make the best possible use of animal waste. The City of Palo Alto Utilities (CPAU) is choosing to support projects in areas where our dollars make a big difference in building and running of the projects. Green Valley Dairy in Krakow, Wisconsin is an example of a project supported by PaloAltoGreen Gas.

Through the use of anaerobic digesters, methane is captured as the manure breaks down and is then destroyed when it is burned as a fuel to produce electricity. Additionally, these digesters can produce a variety of other products that help the farm reduce environmental impact. The fibrous material can be separated, dried and used as bedding while the liquid effluent can be used as fertilizer. Anaerobic digestion also aids local communities by helping to reduce water pollution and odor associated with animal husbandry.

The dairy’s management team operates with sustainability in mind and it’s no wonder that it won the 2013 Outstanding Achievement in Renewable Energy award from the Innovation Center for U.S. Dairy. The dairy:

  • Displaces traditional fossil fuel based grid power
  • Reduces non-carbon local air pollutants such as non-methane volatile organic compounds (VOCs)
  • Separates biosolids to use as animal bedding, also replacing the need to ship in sand regularly
  • Digester outputs organic, largely pathogen-free nutrients for use as fertilizer
  • Reduces agricultural odor in the surrounding community
  • Mitigates energy costs allowing the farm to maintain its workforce

The carbon offsets sold through PaloAltoGreen Gas are Green-e Climate Certified.
