Climate and Environment

CBO outlines the main channels by which climate change and policies intended to mitigate or adapt to it affect the federal budget. Climate change increases budget deficits; investments in mitigation or adaptation could reduce those costs.

This paper describes how CBO constructed its projection of the effect of climate change on U.S. output, how the projected effect should be interpreted, limitations of the analysis, and the central climate-change scenario that CBO used.

Expected annual economic losses from most types of damage caused by hurricane winds and storm-related flooding total $54 billion—$34 billion in losses to households, $9 billion to commercial businesses, and $12 billion to the public sector.

CBO finds that premiums collected by the National Flood Insurance Program for policies in effect in August 2016 fell short of the program’s expected costs by $1.4 billion, mainly because of shortfalls in coastal counties.

In fiscal year 2015, the federal government supported the development, production, and use of fuels and energy technologies through tax preferences totaling $15.8 billion and spending by the Department of Energy totaling $5.4 billion.
