ACR Green Finance Impact Program – Anaerobic Digester Calculator

This calculator tool uses the methods and equations found in the ACR Green Finance Impact Methodology for Diversion of Organic Waste for Anaerobic Digestion Projects to quantify environmental key performance indicators (KPIs) for bond-funded activities that meet the requirements of that methodology. The calculator quantifies the environmental impacts of diverting food waste, yard waste, and mixed organics from landfills for stand-alone anaerobic digestion, including:

  • Greenhouse gas (GHG) emission reductions
  • Bioenergy and/or biofuel generation
  • Landfill diversion
  • Compost or digestate production

Following ACR’s methodology, the tool calculates the project’s environmental KPIs, impact relative to established benchmarks, and Carbon Return (MTCO2e/$-year). Results are presented as the total benefit over the project life and are also normalized as benefits per dollar and benefits in a representative year. When applicable, impacts are also presented as a pro-rated share of the green financing relative to total project costs.
