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 policy brief by the World Resources Institute examines the economic and environmental impacts of increasing corn production to meet the ethanol demands mandated by the Renewable Fuel Standard (RFS).

This research paper analyzes the role of biomass and biofuels in the decarbonization of the United States economy through 2050, arguing that biomass is a limited resource that must be managed with strict carbon accounting and guardrails to avoid unsustainable land use change.

This report introduces the U.S. Public Sector Protocol, a tailored interpretation of the GHG Protocol Corporate Accounting and Reporting Standard designed to help government organizations in the United States quantify and report greenhouse gas emissions.

This expert note from the World Resources Institute recommends that federal and state policymakers maintain and expand incentives, funding, and infrastructure support to accelerate the electrification of the United States' school bus fleet to improve student health and support the clean bus economy.

The World Resources Institute and collaborators developed a geospatial dataset providing benchmark land use change (LUC) and land occupation (LO) emission factors for 42 major crops for the period 2020–24. The dataset aims to harmonize corporate GHG reporting by providing standardized, jurisdiction-level metrics. 2024 national averages reveal high variability in emissions per tonne of crop, such as soy in Brazil (1.67 tCO₂e) versus the US (0.40 tCO₂e), and highlight that subnational data is necessary to identify emission hotspots.

This research paper introduces a framework for Paris-aligned passive investing and evaluates 35 sustainable funds from the United States and the European Union, finding that none are fully aligned with the proposed criteria.

This research paper analyzes the development of solar PV and wind industries in China, Germany, India, Japan, and the United States from 2001 to 2011. It examines how these countries used policy to balance the growth of domestic manufacturing and 'green jobs' with the need for affordable, low-cost clean energy. The study, produced by a collaboration of five research institutions, evaluates the entire value chain from R&D to power generation and is supported by an interactive Data Explorer Tool.

This research paper, conducted by the World Resources Institute (WRI) and Standard & Poor's Rating Services, analyzes how two potential U.S. federal climate policy scenarios—a market-based cap-and-trade system (the American Power Act) and EPA regulation—would affect the credit risk of 13 energy-intensive chemicals subsectors.

This working paper by the World Resources Institute examines how organizations can measure greenhouse gas (GHG) emissions from air travel and implement science-based reduction targets, utilizing case studies from various non-profit and corporate entities.

This fact sheet by the World Resources Institute (WRI) analyzes the potential impacts of the proposed American Power Act (APA) on manufacturing subsectors, specifically focusing on the chemicals industry. It details the APA's permit system for greenhouse gas emissions and the role of free allowance rebates for energy-intensive, trade-exposed industries.

This briefing describes the Carbon Canopy, a partnership of companies, landowners, and NGOs aimed at increasing the area of sustainably managed certified forests in the southern United States by linking forest certification with carbon offset markets.

This briefing, produced by the Center for Strategic and International Studies (CSIS) and the World Resources Institute (WRI), outlines a three-part framework to simultaneously address energy security and climate change in the United States. It argues that the current energy system is unsustainable due to volatile prices, geopolitical tensions, and rising environmental costs, and proposes a balanced package of policy recommendations to transition to a secure, low-carbon economy over several decades.

This fact sheet by the World Resources Institute explains the legal basis and potential mechanisms for the U.S. Environmental Protection Agency (EPA) to regulate greenhouse gas (GHG) emissions under the Clean Air Act following a 2007 Supreme Court ruling and a 2009 EPA endangerment finding.

The report argues that dedicated land use for bioenergy is unsustainable and unrealistic because it competes directly with food production, animal feed, and carbon storage. It recommends phasing out crop-based biofuels and those requiring dedicated land, suggesting that solar photovoltaics offer a far more land-efficient alternative for energy generation.

This research paper by the World Resources Institute examines consumer attitudes toward smart charging, also known as vehicle-grid integration (VGI), based on a survey of current and prospective Honda EV owners in the United States.

Testimony by Jonathan Pershing to the U.S. Senate Environment and Public Works Committee regarding the necessity of technological shifts, a diversified portfolio of mitigation options, and government intervention to address global climate change.

This fact sheet from the World Resources Institute examines how varying international climate policies and the imposition of costs on greenhouse gas emissions affect trade competitiveness, specifically focusing on the risks of industry relocation and emissions leakage.

WRI analyzed the American Power Act's impact on GDP, energy prices, and GHG compliance costs. While most subsectors face modest direct costs, those dependent on natural gas-derived feedstocks face higher risks due to projected price increases, whereas those using coal, petroleum, or electricity-derived materials face limited risk due to projected price decreases.

This working paper by the World Resources Institute analyzes the methodological challenges and diverse approaches used to create citywide transportation greenhouse gas (GHG) emissions inventories, emphasizing their role in developing climate action plans and securing funding.
