subjectEmissions Drivers
These graphs show the changes in emissions drivers in the Power, Buildings, Industry, Transportation, and Agriculture sectors in US
Industry Energy intensity by sector
As manufacturing grew, industrial sectors generally improved their energy intensity, but in some cases performance declined. Structural changes to U.S. industry led to lower emissions intensity.
Transport Emissions intensity
Large gains in vehicle engine and transmission efficiency did not result in significant fuel efficiency gains, as cars became heavier. There was little shifting between transport modes (not shown).
