The World Resources Institute (WRI) created a dataset of U.S. school bus fleets by submitting records requests to state governments between March and November 2022. The data includes details such as model year, fuel type, manufacturer, seating capacity, and ownership model, intended for use in estimating greenhouse gas emission reductions, planning grid upgrades for electrification, and identifying highly polluting buses. The dataset is limited by missing data from four states and all U.S. territories, as well as structural differences in how states report data.

The document outlines four types of solar metering arrangements designed to overcome the limitations of the traditional "one customer, one meter" model. Net metering provides benefits to a single customer via one meter. Virtual net metering (VNM) allows multiple customers with separate meters to share credits from a system, often in multi-tenant or municipal buildings, and is permitted in states including California, Colorado, and Massachusetts. Community solar enables joint ownership or sponsorship of systems for those unable to host arrays on-site, utilizing models such as utility-sponsored, special purpose entity, or non-profit "buy a brick" projects. Meter aggregation allows a single customer with multiple utility accounts to aggregate annual consumption across separate buildings, enabling the installation of larger systems and higher power sales back to the grid.

The document highlights that wind power purchase agreements (PPAs) are cheaper than new coal and natural gas plants across most U.S. regions, even without federal tax incentives. It provides specific examples of solar PV projects outcompeting fossil fuels in states like Utah, Colorado, and Georgia. To sustain these trends, the text recommends increasing federal R&D funding, reforming tax incentives to be refundable, and establishing long-term regulatory certainty through carbon pricing or greenhouse gas standards.

The document argues that integrating natural infrastructure—such as forests and wetlands—with built infrastructure can reduce water treatment costs and enhance water security. It provides a framework for 'green-gray analysis' to compare these options, discusses the scientific links between forest cover and water quality, and outlines various finance mechanisms and stakeholder engagement strategies to scale these efforts across the U.S.

Xcel Energy's Certified Renewable Percentage (CRP) program enables customers to account for the renewable energy already present in the local grid mix by retiring Renewable Energy Credits (RECs) on their behalf. Launched in Wisconsin and Minnesota, with pending approval in Colorado, the program allows cities and corporations to combine grid-based renewable credits with voluntary purchases, such as the Renewable*Connect program, to reach goals of up to 100% renewable energy. The program's application varies by state based on tariff structures, and Xcel Energy provides calculator tools to help customers determine their specific renewable percentages.

Kipster is expanding its circular egg production model from the Netherlands to the US, partnering with MPS Egg Farms and The Kroger Co. The model focuses on using surplus food for feed, achieving carbon neutrality through renewable energy and offsets, and improving animal welfare by raising roosters for meat instead of culling them. In the US, the operation is based in Indiana, utilizing pasta surplus and other by-products to reduce land use and greenhouse gas emissions.

The report analyzes food loss in the US specialty crop sector, contrasting the high loss rates of the fresh market with the relatively lower rates of the vertically integrated processing market. It highlights how contract-based purchasing and mechanical harvesting in the processing sector reduce in-field waste, while the fresh market suffers from strict cosmetic standards and labor shortages. The document proposes using real-time measurement and alternative harvesting models, such as the Whole Crops Harvest pilot, to rescue surplus produce for secondary markets and donations.

The report outlines the essential structural elements of Extended Producer Responsibility (EPR) programs, detailing how the choice of Producer Responsibility Organization (PRO) systems, operational responsibilities, cost coverage, financial models, fee structures, and funding mechanisms influence environmental and economic outcomes. It emphasizes the importance of harmonization across jurisdictions and the use of eco-modulated fees to incentivize sustainable packaging design.
