Michigan HB 5711 to Repeal Clean Energy Standards Passes House and Moves to Senate Committee
In May 2026 the Michigan Legislature advanced HB 5711, a bill to repeal the state’s statutory clean and renewable energy standards under the 2008 Clean and Renewable Energy and Energy Waste Reduction Act. If enacted, this would roll back utility-level renewable and efficiency obligations in Michigan, potentially reshaping decarbonisation plans and energy-sourcing strategies for large energy users in the state.
Vermont Senate Finance Committee Backs H.727 Sustainable Data Centers Bill With PFAS Wastewater Controls
Vermont’s Sustainable Data Centers Act (H.727), which includes stringent PFAS-related water and wastewater controls for large data centres, has advanced in the Senate following a favourable report from the Finance Committee on 14 May 2026. If enacted, large data centre projects in Vermont would need to plan for closed-loop cooling, expanded water and PFAS permitting and monitoring, and long-term grid contracts that protect other ratepayers, materially affecting site selection, infrastructure design, and operating strategies.
Pennsylvania HB2515 Proposes Transparency Requirements for Large Commercial Data Centers
In May 2026, Pennsylvania introduced HB 2515, the Commercial Data Center Transparency Act, to require large data centers to disclose water use, energy demand and related impacts as part of key state permitting processes. If enacted, the bill would create new reporting, public transparency and penalty risks for operators and utilities, influencing siting decisions, infrastructure cost allocation and community engagement around data center projects in the state.
Germany: Cabinet Approves Draft Building Modernisation Act
The German Cabinet has approved a draft Building Modernisation Act that would replace the existing Building Energy Act and amend the Building Electromobility Infrastructure Act, moving from a rigid 65% renewables rule towards a more technology-neutral framework with continued heat-pump support and future green-fuel quotas. If adopted, this package will reset planning assumptions for heating system choices, fuel supply and building retrofit strategies in Germany’s residential and non-residential stock over the rest of the decade, while serving as the main vehicle for implementing the new EU Energy Performance of Buildings Directive.
China Issues Gold Industry Wastewater Standard YS/T 3050-2026 and Adds Related Transport Energy and Wastewater Standards
China has issued a new national gold industry standard (YS/T 3050-2026) on integrated recovery and recycling of gold-processing wastewater, alongside additional 2026 transport-sector standards on sewage reuse, anticorrosion coatings and energy-efficient power systems. These developments tighten expectations on wastewater treatment, corrosion protection and energy efficiency in mining and transport infrastructure, requiring operators to review projects and investments ahead of the November 2026 implementation date for the gold wastewater standard.
Australia Extends NatHERS Support for Existing Homes Assessors and Confirms NCC 2025 Release
Australia’s NatHERS Administrator is extending accreditation fee subsidies and free magicplan access for existing homes assessors to 30 June 2027, while confirming the 1 May 2026 release of NCC 2025 and a mid‑2026 Stage 2 rollout for existing homes ratings. For building and energy teams this means limited new residential energy efficiency obligations under NCC 2025, continued support to build the assessor workforce, and clear timelines to prepare software, training and governance for future disclosure or retrofit programmes.
EU Commission Publishes ESPR Preparatory Study on Commercial and Industrial Laundry Appliances
In May 2026 the European Commission’s DG Environment published a major preparatory study assessing commercial and industrial laundry appliances under the Ecodesign for Sustainable Products Regulation framework.
