US
carbon emissions rise 2%
Boost
in coal consumption saw US energy sector emissions rise in 2013 after
years of declining

Energy-related
carbon dioxide pollution grew by 2% last year after declining several
years in a row, a government report said Monday. The increase was
largely due to a small boost in coal consumption by the electric
power industry, according to the study by the US Energy Information
Administration.
American
cars and factories spewed 5.38 billion tons of carbon dioxide in
2013, up from 5.27 billion in 2012, the report said. Carbon dioxide
is the chief man-made global warming gas.
Coal,
long the dominant source for US electricity, has regained some market
share in recent months as natural gas prices have increased following
historic lows in 2012. Coal generated about 39% of the nation's
electricity in October, compared with 28% for natural gas, the EIA
said. Coal supplied about 37% of US electricity in 2012, with natural
gas at 30%.
Even
with the uptick, overall US carbon emissions remained 10% below 2005
levels, more than half the reduction needed to achieve President
Barack Obama's goal of reducing carbon emissions by 17% from 2005
levels by 2020.

Obama
has launched a major second-term drive to combat climate change,
bypassing Congress as he imposes first-ever limits on carbon
pollution from new and existing power plants.
40%
of US carbon emissions, and one-third of greenhouse gases overall,
come from electric power plants, according to the EIA.
Under
Obama's plan, the Environmental Protection Agency will propose
guidance for states to regulate greenhouse gas emissions from future
power plants, as well as those already in existence, to reshape where
Americans get electricity. The plan is intended to help move the
United States from a coal-dependent past into a future fired by
cleaner sources of energy such as wind and solar power, nuclear
energy and natural gas.
The
EPA says the plan would not raise the price of electricity or cause
major disruptions to the US economy, a claim the coal industry and
its allies in Congress dispute.
Obama's
plan also would boost renewable energy production on federal lands,
increase efficiency standards and prepare communities to deal with
higher temperatures that many scientists say are being caused by
human activity. The 12 hottest years on record all have occurred in
the past 15 years.
