Agency Emissions Reductions
Title Legal Authority Originating Legislation Summary
Achieving Net-Zero Emissions Buildings, Campuses, and Installations

The Federal Government will work across its portfolio of owned and leased buildings to increase water and energy efficiency; reduce waste; drive decarbonization of Federal buildings; and achieve net-zero emissions across the Federal portfolio of buildings, campuses, and installations by 2045.

Achieving Net-Zero Procurement

In order to achieve net-zero procurement by 2050, while increasing the sustainability of Federal supply chains, the Federal Government will leverage the power of its procurement to catalyze action by Federal suppliers. These supply chain initiatives include major contractor GHG emission disclosures paired with science-based targets, a "buy clean" initiative for low-carbon materials, and a sustainable products policy.

Government-Wide Goals

The Federal Government will lead by example to achieve a carbon pollution-free electricity sector by 2035 and net-zero emissions economy-wide by no later than 2050, and to use the Federal Government's scale and procurement power in achieving these goals.

Reducing Agency Greenhouse Gas Emissions

Section 202 of the E.O. directs agencies to establish reduction targets for scope 1, 2, and 3 greenhouse gas emissions, as defined by the Federal Greenhouse Gas Accounting and Reporting Guidance (see also section VII of this OMB memo M-22-06 ), for fiscal year 2030 with annual progress targets, measured from a fiscal year 2008 baseline.

Transitioning to 100 Percent Carbon Pollution-Free Electricity

The Federal Government will execute a whole-of-government approach to increase use, production, and facilitation of carbon pollution-free electricity and storage to achieve this goal.

Transitioning to a Zero-Emission Fleet

Each Federal agency will acquire ZEVs in all vehicle classes as vehicles come to market. Each Federal agency will acquire ZEVs for 100 percent of all light-duty vehicles by 2027 and all medium- and heavy-duty vehicles by 2035. Federal agencies will achieve the path to the acquisition targets through planning, coordination, and collaboration, informed by agency mission, ZEV model availability, and funding.

Climate Change and Adaptation Planning
Title Legal Authority Originating Legislation Summary
Adapting the Federal Government to the Impacts of Climate Change

Modernize Federal policy, programs, operations, and infrastructure to support climate resilient investment.

Federal Climate Adaptation Plans

Agencies will develop climate adaptation and resilience plans that evaluate the most significant climate change related risks and vulnerabilities in agency missions and operations, and identify actions to manage and mitigate those risks and vulnerabilities. Agencies will provide annual updates to these plans. At a minimum, major updates will occur after every National Climate Assessment and every four years. Agencies also will assess and report on implementation activities and progress annually. The Council on Environmental Quality (CEQ) and Office of Management and Budget will review, evaluate, and monitor these reports, in coordination with agency officials, as part of a robust process to continually improve the effectiveness of agency planning and implementation.
