The Biden administration has finalized standards for federal buildings that will eliminate onsite fossil fuel usage for new projects by 2030. The new rule requires 90 percent cuts to emissions from new construction between 2025 and 2029, with onsite emissions eliminated from all new projects and major renovations beginning in 2030. The administration projects that the cuts will save $8 million in taxpayer funds from equipment and infrastructure expenses, and they will eliminate 2 million metric tons of carbon emissions and 16,000 tons of methane emissions over the next three decades. The rule defines ‘major’ renovations as those costing $3.8 million or more, meaning ‘smaller projects’ will be excluded. The rule also includes an option to apply for limited, case-by-case exemptions for scenarios, such as supply chain issues or issues with a building’s physical structure that make the technological adaptations impractical.
