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.
Since the 1960s, the Bureau of Safety and Environmental Enforcement has allowed the offshore oil and gas industry to leave 97% of pipelines (18,000 miles) on the seafloor when no longer in use. Pipelines can contain oil or gas if not properly cleaned in decommissioning.
Katrina, Sandy, Harvey, and Irma—4 of the costliest hurricanes in the U.S. since 2005—caused damage totaling trillions of dollars. Their effects on economic activity and employment in damaged areas varied widely.
Climate change has led to record low levels of ice in the U.S. Arctic—prolonging the shipping season and opening up shipping routes. This may expand economic opportunities, but harsh weather and ice conditions—plus the lack of maritime infrastructure—pose safety risks.
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.
Since 1980, weather disasters in the U.S. have caused more than $1.6 trillion in damage. Weather disasters, and federal spending on them, are expected to increase due to climate change, as our High Risk List indicates.
Shellfish aquaculture projects—the breeding, rearing, and harvesting of oysters, clams, and mussels—may require authorization from the U.S. Army Corps of Engineers. Among other things, the Corps examines compliance with navigation and environmental laws.
