This issue brief examines how climate change impacts United States national security, detailing the Department of Defense's (DOD) conceptualization of climate change as a 'threat multiplier' and the resulting operational, infrastructural, and geopolitical challenges. It outlines the adaptation and mitigation strategies adopted by the DOD and other security agencies, while analyzing the role of Congressional legislation and funding in shaping these efforts.

This briefing discusses the challenges of meeting 2025 Corporate Average Fuel Economy (CAFE) and greenhouse gas (GHG) standards, proposing high-octane, low-carbon fuels as a cost-effective compliance pathway for the automotive industry and consumers.

This briefing by the Environmental and Energy Study Institute argues that the United States must proactively plan for climate-induced migration to avoid regional instability and humanitarian crises. It highlights the lack of legal protections for environmental migrants and the specific risks of agricultural decline in Mexico and Central and South America, while noting the potential strain on U.S. military resources tasked with humanitarian aid.

This fact sheet from the Environmental and Energy Study Institute describes the process and benefits of using anaerobic digestion to convert organic waste—including livestock manure, food waste, and wastewater—into biogas. It outlines the potential for biogas to provide baseload power, reduce methane emissions, and create jobs in the United States, while detailing the regulatory frameworks and funding programs that support the industry.

This fact sheet describes the Consumer and Fuel Retailer Choice Act (S.517, H.R. 1311), a legislative proposal to amend the Clean Air Act to allow the year-round sale of E15 fuel. It explains how current Reid Vapor Pressure (RVP) standards inadvertently block E15 sales during summer months, the environmental and economic impacts of these restrictions, and the potential for higher ethanol blends to reduce greenhouse gas emissions and fuel costs.

This fact sheet examines the environmental, health, and economic implications of the Consumer and Fuel Retailer Choice Act (S.517, H.R. 1311), which proposes amending the Clean Air Act to allow the year-round sale of E15 fuel. It details how current Reid Vapor Pressure (RVP) standards inadvertently restrict E15 sales during summer months, the resulting costs to retailers and consumers, and the potential for higher ethanol blends to reduce greenhouse gas emissions and air pollutants.

This fact sheet describes the formation and goals of the United States Climate Alliance and other subnational efforts to uphold the 2016 Paris Agreement following the Trump Administration's decision to withdraw the United States from the accord.

This fact sheet describes the U.S. Department of Energy's (DOE) program for implementing minimum energy and water efficiency standards for appliances and equipment under the Energy Policy and Conservation Act of 1975. It details the economic, environmental, and technological benefits of these standards, the role of voluntary programs like ENERGY STAR, and the impact of regional standards on heating and cooling products.

This fact sheet from the Environmental and Energy Study Institute provides an overview of plug-in electric vehicles (PEVs), including battery electric vehicles (BEVs) and plug-in hybrid electric vehicles (PHEVs). It details the environmental and economic benefits of PEVs, the current state of the U.S. and global markets, charging infrastructure, battery technology trends, and government incentives.

This fact sheet describes the role of the U.S. Department of Energy (DOE) in implementing and enforcing minimum energy efficiency standards for appliances and equipment under the Energy Policy and Conservation Act of 1975. It details the economic and environmental benefits of these standards, the distinction between mandatory federal standards and voluntary programs like ENERGY STAR, and the impact of regional standards on heating and cooling equipment.

This policy brief by the Environmental and Energy Study Institute (EESI) analyzes the Trump Administration's FY2018 'skinny budget' proposal. It details significant proposed funding cuts across multiple federal agencies, specifically targeting climate change programs, sustainable energy research, rural development, and public transportation infrastructure, while prioritizing national security and space exploration.

This fact sheet describes the role of the U.S. Farm Bill in promoting voluntary on-farm conservation practices to address agricultural pollution, improve soil health, and sequester carbon. It details specific conservation techniques—such as cover cropping, no-till operations, and intercropping—and outlines the primary funding programs managed by the USDA under the 2014 Farm Bill.

This fact sheet from the Environmental and Energy Study Institute (EESI) details the role of the U.S. Farm Bill in promoting on-farm conservation practices. It examines specific conservation tools—such as cover crops, no-till operations, and intercropping—and outlines the funding and objectives of the 2014 Farm Bill's Conservation Title (Title II), including its primary programs: EQIP, ACEP, CRP, and CSP.

A coalition of organizations representing various agricultural, nutrition, and conservation sectors urged U.S. budget and appropriations committees in February 2017 to reject further funding cuts to programs under the jurisdiction of the House and Senate Agriculture Committees, arguing that the 2014 Farm Bill had already contributed significantly to deficit reduction.

This fact sheet by the Environmental and Energy Study Institute (EESI) provides a comprehensive overview of employment in the renewable energy and energy efficiency sectors globally and within the United States as of 2016 and 2017. It utilizes data from the U.S. Department of Energy (DOE) and the International Renewable Energy Agency (IRENA) to compare clean energy jobs against fossil fuel employment and detail specific subsector growth.

This fact sheet by the Environmental and Energy Study Institute (EESI) provides a comprehensive overview of employment trends in the renewable energy and energy efficiency sectors within the United States and globally, primarily using data from the U.S. Department of Energy (DOE) and the International Renewable Energy Agency (IRENA) as of 2016 and 2017.

Richard Ottinger, EESI Board Chair Emeritus, proposes that the United States treat climate change mitigation as a form of risk management or an insurance policy to protect against the catastrophic outcomes predicted by 95 percent of climate scientists.

This fact sheet by the Environmental and Energy Study Institute examines the impact of agricultural nutrient runoff—specifically nitrogen and phosphorus—on water quality in the United States, focusing on the Upper Midwest, the Great Lakes, and the Gulf of Mexico. It details the environmental consequences of eutrophication and hypoxia, the legal and regulatory landscape including the Clean Water Act's exemptions for irrigated agriculture, and the role of the USDA's Regional Conservation Partnership Program (RCPP) in funding voluntary conservation efforts to reduce pollution.

This fact sheet from the Environmental and Energy Study Institute provides a historical overview of octane additives in U.S. gasoline, detailing the transition from lead and other petroleum-based aromatics to ethanol due to health and environmental concerns. It discusses the role of the EPA in regulating fuel composition to reduce tailpipe emissions and improve engine efficiency.

The Harry and Jeanette Weinberg Commons is a multi-family retrofit development in Washington, D.C., designed as the first Passive House of its kind in the U.S. to provide affordable housing for low-income and formerly homeless families while drastically reducing energy costs.
