HB 1458 requires large new construction, additions, and renovations (50,000+ square feet) to reduce embodied carbon emissions from building materials. It offers three compliance paths: reusing 45% of existing structures, demonstrating a 90% reduction in emissions for covered materials, or conducting a whole-building life-cycle assessment. Projects must report data through a public database managed by the Department of Commerce, including material choices and compliance methods. The law applies to all covered projects under the International Building Code and mandates verification by licensed design professionals.

HB 1481 mandates a study on the potential benefits of advanced nuclear energy, specifically small modular reactors, for Washington's clean energy goals. The joint legislative audit committee must contract a third party to examine how nuclear energy could support grid decarbonization by 2045, create jobs, and potentially replace coal-fired power plants. The study must include recommendations on workforce development and feasibility of nuclear deployment, with a report due to the legislature by July 1, 2027. This bill does not enact new policy but directs a formal review of nuclear energy's role in the state's energy future.

HB 1871 creates a state incentive program to help homeowners install grid-connected residential battery storage systems, primarily benefiting low- and moderate-income households. Utilities must establish approved incentive programs requiring at least 40% of benefits to reach these households, with options for time-of-use electricity rates or participation in utility-run virtual power plants. The program mandates income verification for qualifying customers, prohibits leasing, and requires utilities to document costs and protect customer data. Approved programs must be audited biennially by Washington State University Extension. The bill aims to increase grid resilience during outages while supporting clean energy goals.
