US total greenhouse gas emissions rose 0.8% in 1999 to 1,833 million tonnes of carbon equivalent (MMTCe), according to government estimates, compared to 1998 levels. Analysts at the US Energy Information Administration said the increase was slightly lower than the 1.1% average annual increase that characterized total US greenhouse gas emissions during the 1990s but significantly higher than the 0.1% growth between 1997-1998.
