This executive summary, produced by the Stockholm Environment Institute for the Combat Climate Change (3C) initiative, examines how resource scarcity in biomass, metals, and water could hinder the transition to a low-carbon economy. It evaluates various scenarios for resource availability and proposes strategies—including technological innovation, policy shifts, and efficiency improvements—to ensure the viability of green technologies.

The Stockholm Environment Institute (SEI) has introduced the Water Beyond Boundaries (WBB) initiative to address gaps in Integrated Water Resource Management (IWRM). WBB seeks to create a new agenda for sustainable water planning by focusing on tele-connections beyond the watershed, early integration of ecosystem needs, and multi-scale participatory approaches to address social inequalities.

This fact sheet describes WEAP (Water Evaluation and Adaptation Planning), a software tool developed by the Stockholm Environment Institute for integrated water resources planning and policy analysis.

This fact sheet by the World Resources Institute explains the function, types, and regulatory status of greenhouse gas (GHG) emissions registries, specifically focusing on the legal requirement for the U.S. Environmental Protection Agency to establish a national mandatory registry by mid-2008.

This briefing analyzes 23 subnational case studies from Asia, Europe, Latin America, and North America to provide recommendations for developing electric mobility (e-mobility) roadmaps in Vietnamese cities, specifically Da Nang, Hanoi, and Ho Chi Minh City.

This guide by the World Resources Institute outlines five public-private financing mechanisms designed to overcome capital barriers for energy efficiency investments: on-bill financing, Commercial Property Assessed Clean Energy (PACE) financing, Sustainable Energy Utility (SEU) models, loan guarantees, and loan loss reserve funds (LLRFs).

Dr. Jonathan Pershing of the World Resources Institute provided testimony to the US Senate Environment and Public Works Committee supporting the America’s Climate Security Act of 2007 (S. 2191). He argued that the bill's cap-and-trade system would provide a necessary price signal to reduce greenhouse gas emissions at modest economic costs while positioning the United States to lead international climate action.

This report by the World Resources Institute examines how state-level climate policy innovation in the United States can influence federal regulation, a process termed "vertical diffusion." By analyzing thirteen cases of policy diffusion and specific initiatives like the Regional Greenhouse Gas Initiative (RGGI) and California vehicle emissions standards, the report identifies key drivers that encourage the federal government to adopt state-led climate policies.

A policy brief by the World Resources Institute arguing that the United States should shift its sustainable aviation fuel (SAF) strategy away from food and feed crops to avoid increasing food prices and environmental degradation, focusing instead on waste biomass, captured carbon, and clean hydrogen.

This briefing paper by the World Resources Institute analyzes the state of climate finance, carbon pricing, and data disclosure in the United States and China. It details the U.S. reliance on subnational carbon markets and the SEC's evolving disclosure rules, alongside China's implementation of the world's largest emissions trading scheme (ETS) and its 'South-South' finance mechanism. The document concludes by suggesting areas for bilateral cooperation, specifically in sustainable procurement, data standards, and subnational carbon market exchanges.

This briefing by the World Resources Institute provides a detailed status report on the climate policies, energy trends, and international cooperation of China and the United States as of early 2024. It outlines China's progress toward its 2030 and 2060 goals, the United States' implementation of the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA), and the diplomatic efforts to maintain bilateral climate cooperation despite broader geopolitical tensions.

This briefing paper provides a detailed status update as of April 10, 2024, on the climate policies, energy trends, and bilateral engagement between China and the United States. It outlines China's progress toward its 2030 and 2060 carbon goals, the U.S. implementation of the Inflation Reduction Act (IRA) and Infrastructure Investment and Jobs Act (IIJA), and the diplomatic efforts to maintain climate cooperation despite broader geopolitical tensions.

This report by the World Resources Institute provides a comprehensive guide for U.S. businesses on the deployment and financing of on-site renewable energy systems, including solar photovoltaic, solar thermal, wind, and geothermal heat pumps. It details the economic and financial benefits, various ownership and financing models, and the associated risks and objectives for corporate energy management.

This briefing by the World Resources Institute outlines opportunities for bilateral cooperation between the United States and China to reduce methane emissions, specifically focusing on the agriculture and waste/wastewater sectors. It identifies specific technical areas for R&D, the potential for remote sensing collaboration, and the role of economic and regulatory incentives in driving mitigation.

This report by the World Resources Institute (WRI), updated April 26, 2023, tracks the adoption of electric school buses (ESBs) in the United States. Based on data through December 31, 2022, it highlights a rapid increase in 'committed' buses—those awarded, ordered, delivered, or operating—driven largely by the EPA's Clean School Bus Rebate Program. The report analyzes the geographic distribution of these buses, the impact of funding sources, the types of buses being adopted, and the equity of distribution across low-income and minority communities.

This report by the World Resources Institute (WRI) tracks the adoption of electric school buses (ESBs) in the United States as of September 30, 2022. It details the number of committed vehicles, the primary funding sources driving adoption, the types of buses being purchased, and an analysis of whether the transition is occurring equitably across different demographic and pollution-burdened areas.

This report by the World Resources Institute (WRI) analyzes the adoption of electric school buses (ESBs) in the United States as of June 30, 2022. It tracks 'committed' buses—those awarded, ordered, delivered, or in operation—and examines the distribution of these vehicles across different states, income levels, and demographics to assess the equity of the transition from diesel-powered fleets.

As of October 2024, the U.S. has 12,241 electric school bus commitments, with nearly 5,000 already in operation. Adoption is heavily driven by the EPA's Clean School Bus Program, which has prioritized high-poverty, rural, and tribal districts. While California remains the leader in total buses, adoption is increasing across the Midwest and New England. The report highlights that 62% of committed buses are in districts with the highest shares of low-income households and 85% are in districts with the highest percentages of people of color.

This case study examines the response of the state of Acre, Brazil, to severe droughts and wildfires in 2005 and 2010. It details the implementation of a centralized 'situation room' to coordinate fire-fighting efforts using satellite data and technical expertise, while analyzing the environmental impacts, policy interventions, and systemic barriers to fire control in the western Amazon.

This WWF South Africa fact sheet examines the role of desalination as a water source for Cape Town and South Africa, detailing the technical requirements, costs, and environmental impacts of the process.
