This bill mandates that the Department of Administrative Services incorporate proxy carbon pricing into its procurement processes, specifically for transportation and building project costs. A new section, RSA 21-I:14-e, is added to define "proxy carbon pricing" and outlines that starting January 1, 2026, the department must use a proxy carbon price of $85 per ton, which will increase by $10 annually until it reaches $2050. The bill also specifies that the carbon emissions from natural gas will be calculated using a methane multiplier to account for leakage.

The bill does not provide funding or authorize new positions, leading to indeterminable expenditures for the state. The Department of Administrative Services has indicated that while the bill will require additional staff to calculate and analyze carbon metrics, the exact number of staff hours and associated costs cannot be predicted. The fiscal impact is expected to manifest after FY 2026, but no specific revenue or funding sources are identified in the bill.
