GAO’s reports and testimonies give Congress, federal agencies, and the public timely, fact-based, non-partisan information that can improve government operations and save taxpayers billions of dollars.
Until the 1970s, mine operators could mine for valuable hardrock minerals—i.e., gold or copper—then abandon the land. On lands they oversee, federal agencies identified about 140,000 remnants of these hardrock mines, including unsecured tunnels and toxic waste piles.
Extreme weather related to climate change potentially threatens utilities that produce drinking water and treat wastewater.
We examined federal technical and financial assistance to make such infrastructure more resilient to extreme weather and asked experts about additional options.
Small communities may lack the resources needed to maintain or replace drinking water systems. New or nonconventional approaches have the potential to do a better, more cost-effective job of providing drinking water.
Environmental justice seeks to address the disproportionately high health and environmental risks found among low-income and minority communities by seeking their fair treatment and involvement in environmental policy.
Researchers often use animals to study disease, test product safety, experiment, or teach. Some uses cause animals pain or distress. Federal agencies require researchers to consider alternatives to animal use, such as computer modeling or working with cell cultures.
We testified about our earlier work on “sustainable chemistry” that drew on an extensive literature review, 82 interviews, a meeting of experts, and a survey of 27 chemical companies.
These sources didn't agree on how to define sustainable chemistry or measure sustainability.
Millions of Americans are unsure about where their next meal will come from. Meanwhile, about 40% of the U.S. food supply goes uneaten. This issue requires action across the food supply chain and collaboration among federal and state agencies, businesses, communities, and more.
There were 14 separate billion-dollar weather and climate disaster events in the U.S. in 2018—with a total cost of at least $91 billion. These costs will likely rise as the climate changes, researchers say.
We reviewed the effects of the Renewable Fuel Standard, which requires biofuels to be blended into U.S. transportation fuels in increasing volumes.
The standard was associated with modest gas price increases in areas outside of the Midwest. Most corn ethanol—the most common U.S.
