Key features in electricity and CO2: OECD Pacific

► Electricity-related CO2 emissions have increased by 3.3% annually over the last decade, against 2.6% in the 1990-1998 period. The CO2 intensity of power generation has been stable since 2002 at 0.5 tCO/MWh.

► The relatively balanced fuel mix in power generation hides striking country-by-country differences, with Australia relying mostly on coal; Japan using a diversified mix, reflecting resource constraints; and Korea showing a rapid uptake of coal and increasing nuclear generation following electricity demand that more than quadrupled since 1990.

► The intensity of final electricity use per GDP has grown by 0.5% annually since 1990, although it has been relatively stable over the last decade. Final electricity use has grown by 62% since 1990, in spite of a 1.6% drop in 2008 as a result of the recession.

► CO2 from electricity accounts for 44.6% of the region's total CO2 emissions, higher than in Europe or OECD North America.

► The share of non-fossil fuel generation has declined since 1990, from 36% to 31% in 2008. Among OECD regions, the growth in non-hydro renewables has been the lowest in OECD Pacific, from 15 to 40 TWh between 1990 and 2008. Wind recorded the fastest growth in the 1998-2008 decade.

► Japan accounts for half of the region's CO2 emissions from electricity. The Fukushima accident will most probably increase the CO2 intensity of power generation in Japan in the coming years.

► Australia and Korea face some uncertainty, with ongoing political processes to introduce emission trading schemes. Japan has stepped back for now from a national emissions trading system and was considering a carbon taxation program.

► Nuclear is projected to represent the largest additions in capacity in this region.
