HB 870, the "Large Buildings for Tomorrow Act," requires new construction of large commercial and multifamily residential buildings (over 35,000 square feet) to meet specific energy conservation standards set by the Maryland Department of Labor. The bill defines "covered buildings" to include most large commercial structures and state-owned buildings, but excludes historic properties, schools, manufacturing facilities, and agricultural buildings. It mandates that adopted energy conservation requirements must be at least as stringent as the International Energy Conservation Code, with the state allowed to set stricter standards to improve efficiency. The law also establishes clear definitions for terms like "energy conservation measure" to guide implementation and ensure consistency.

HB 640 repeals outdated or unnecessary government reporting requirements, boards, and commissions to improve administrative efficiency. It specifically eliminates obsolete entities like the Renewable Fuels Incentive Board, Two-Generation Family Economic Security Commission, and the requirement for the Department of Health to report on hepatitis B/C virus activities. The bill also removes redundant reporting mandates, such as those for the Criminal Justice Information Advisory Board and several working groups under the Commission on Climate Change. These changes streamline state operations by removing duplicative or obsolete structures without creating new policies or obligations.

HB 437, the Transportation and Climate Alignment Act of 2026, requires Maryland’s Department of Transportation to conduct impact assessments for major highway expansion projects costing over $100 million. These assessments must evaluate greenhouse gas emissions and vehicle miles traveled, and the department must develop a multimodal transportation program (including transit, biking, and pedestrian improvements) to offset emissions from the project. The program must prioritize overburdened and underserved communities affected by the project, aiming for net-zero or negative greenhouse gas emissions when combined with the highway project. This applies to projects not already funded or reviewed before June 30, 2026, and affects highway planning decisions across the state.
