IEA: Energy emissions rose to record high in 2012

The International Energy Agency says the world's energy-related carbon dioxide emissions rose 1.4 per cent in 2012 to a record high of 31.6 gigatons, even as the US posted its lowest emissions since the mid-1990s.

In a report released today, the IEA says China saw the largest emissions growth last year, but the increase was among the lowest seen in a decade amid investments in renewable energy and energy efficiency.

The IEA says the energy sector accounts for about two-thirds of global emissions of CO2 and other greenhouse gases, which scientists say are fueling climate change.

Global climate talks are aimed at keeping the temperature rise below 2 degrees Celsius compared to pre-industrial levels. The IEA found the world's on track for an increase of 3.6-5.3 C.
