U.S. Greenhouse Gas Emissions Stabilizing

Despite economic growth of almost four percent, U.S. CO2 emissions rose only .4 percent in 1998, the smallest increase since 1991. Since CO2 emissions equal about
84 percent of all U.S. greenhouse gas emissions they are a good indicator of total emissions.

Increased summer electricity use was offset by a very warm winter, reducing fuel
use (the irony of global warming). The transportation sector, which constitutes
about a third of emissions, increased by 1.8 percent while industrial emissions declined by 1.2 percent. Utilities used higher emitting, cheap oil instead of
natural gas resulting in 3.2 percent higher emissions.
