The Environmental Protection Agency on Tuesday published the U.S.'s 19th annual emissions tally to the U.N. Framework Convention on Climate Change.

The U.S. uses 2005 pollution levels as its benchmark to measure emissions cuts, and has a target to lower emissions by 17 percent from that starting point by 2020.

Since 1990, the first year the U.S. kept the inventory, carbon dioxide emissions - largely energy-related emissions and the most prevalent greenhouse gas - rose just 5.4 percent.

Meanwhile hydrofluorocarbons (HFCs), super greenhouse gases used primarily as refrigerants, saw a dramatic rise of over 309 percent.

The Obama administration has taken steps to reduce these emissions through bilateral and multilateral agreements with major polluters, including China, the world's biggest greenhouse gas emitter, and India.

The EPA prepares the annual report in collaboration with other federal agencies and is subject to public comments.

A United Nations report released Sunday said that governments must act faster to keep global warming in check and that a radical shift from fossil fuels to low-carbon energy such as wind, solar or nuclear power would shave only about 0.06 of a percentage point a year off world economic growth.


The Obama administration's climate action plan, now being implemented, is expected to steer the U.S. to meet its 17 percent target by 2020.
