What Is WAIRE?

Understand how Warehouse Actions and Investments to Reduce Emissions can affect your supply chain

Warehouse Actions and Investments to Reduce Emissions (WAIRE), sometimes called the Indirect Source Rule, is a truck traffic-based credit and deficit system impacting class 2B to class 8 trucks. Under the rule, some facility operators must monitor and submit accurate vehicle travel data, and they must earn a specified number of points through emissions-reducing activities or pay mitigation fees. The regulation also requires warehouses with ≥100,00 ft2 of indoor space within a single building to complete emission mitigation actions and investments.
