In partnership with HF&H and with funding from CalRecycle, Cascadia built the Commercial Climate Calculator for virtually any California business to evaluate financial, economic, and climate benefits associated with various waste reduction and recycling strategies. This tool is part of a larger effort by CalRecycle to support businesses and local jurisdictions in meeting mandatory commercial recycling program requirements. The calculator development process consisted of two rounds of stakeholder testing and public presentations, and benefited from direct involvement of more than 70 business, industry, and government representatives. Cascadia also collaborated with the California Air Resources Board and UC Berkeley to provide a waste and recycling module for the CoolCalifornia carbon footprint small business calculator.
