Across the news desk recently came an announcement from the California Sustainable Winegrowing Alliance, introducing an online tool for calculating greenhouse gas emissions and carbon sequestration in California vineyards. The tool, named the DeNitrification and DeComposition (DNDC) model for winegrapes, was developed to help winegrowers “measure to manage” to reduce input costs and emissions.
The tool is part of CSWA’s online Sustainable Winegrowing Self-Assessment and Performance Metrics system, the latter of which measures, manages and tracks energy, water and nitrogen use, and greenhouse gas emissions. The tool was developed with partial funding from a three-year California Department of Food and Agriculture Specialty Crop Block Grant.
CSWA worked with Applied GeoSolutions, UC Davis, SureHarvest, the USDA Agricultural Research Service and other project partners over several years to calibrate and validate the DNDC model for winegrapes, assess the influence of vineyard management practices on greenhouse gas emissions and create a user-friendly tool for use by California winegrowers.
To begin using the DNDC tool within the Performance Metrics site, visit https://metrics.sustainablewinegrowing.org where California participants can log in with their CSWA Username and Password or request a new Username.
