The waste sector is the third largest source of human-driven methane emissions, contributing 18% of global anthropogenic methane in 2020, with municipal solid waste accounting for 11% and wastewater for 7%. Mitigation efforts are currently hindered by a lack of data on landfills and dumpsites and limited access to evidence-based best practices. To address this, the Clean Air Task Force and RMI are launching the Waste Methane Assessment Platform (Waste MAP), an open-source online tool designed to improve data availability, provide a heat map of emissions, and offer strategic playbooks for mitigation. In 2023, the initiative includes engagement in six countries: Mexico, Colombia, and Ecuador (via CATF), and India, Nigeria, and the United States (via RMI), providing technical assistance and capacity building to help these nations meet the Global Methane Pledge and other greenhouse gas targets.

The report evaluates alternative financing for California's high-voltage transmission expansion needed for its 2045 clean energy goals. It finds that a Public-Private Partnership (PPP)-Lease model could save ratepayers up to $3 billion annually, or $123 billion over 40 years, by utilizing low-cost public debt and competitive procurement.

The document argues that traditional investor-owned utility (IOU) financing for transmission projects risks increasing consumer rates and proposes public financing as a lower-cost alternative. Research focused on California indicates that a "lease-type" public-private partnership could save ratepayers up to $3 billion annually, or $123 billion over 40 years, by utilizing low-cost public debt, reducing taxes, and maintaining private sector operational efficiency. The brief outlines several public financing mechanisms, such as public bonds and loans, and provides policy recommendations for other states to implement similar cost-saving reforms, including the use of credit enhancements and the designation of state-level coordinators for high-priority transmission lines.

The document highlights superhot rock geothermal as a scalable, carbon-free energy source that could significantly exceed Wyoming's current electricity needs while utilizing the state's existing oil and gas expertise.

The document highlights that just 1% of Yemen's superhot rock geothermal resource could provide 1,052 GW of energy capacity, far exceeding the country's 2021 electricity consumption of 2,913 GWh. It argues that this energy source could offer a low-land-footprint, reliable alternative to fossil fuels, supporting desalination, hydrogen production, and economic growth.
