A new study has determined that China would play a major role in doubling of global greenhouse emissions by 2030.
According to a report in news.com.au, the study says that rapid economic growth in China is fuelling the increase in worldwide emissions and calls for developing countries to commit to binding emissions reduction targets to avoid such a "bleak" outcome.
AdvertisementThe study, headed by Professor Garnaut, an economist who heads the Government's Garnaut Review, predicts the world reaching a level of emissions 20 years earlier than that predicted by the groundbreaking Stern Review by British economist Nicholas Stern.
In the "platinum age" - a term coined by Professor Garnaut for the current period of exceptionally fast economic growth led by China and India - fossil-fuel emissions are spiralling.
"CO2 emissions from fossil-fuel burning increased by only one per cent a year on average in the 1990s, but grew by three per cent a year from 2000 to 2005," the draft paper said.
"Since 2000, non-OECD emissions have been growing almost six times as fast as OECD emissions, accounting for 85 per cent of the growth in emissions," it added.
Under platinum age projections, the academics said that China would be responsible for 37 per cent of global emissions by 2030.
The projections suggest that emissions will grow by 2.5 per cent a year in the 2005-2030 period to a level of 83 billion tonnes, almost double their current level.
Global effort to cut greenhouse gases will need to be much larger to avoid the projected scenario, it added.
"Larger and earlier cuts in developed country emissions will be required than previously thought, and major deviations from baselines will be required in developing countries by 2020," the study said.
"It is hard to see how the required cuts could be achieved without all major developing, as well as developed, countries adopting economy-wide policies to reduce emissions," he added.
The Garnaut Review's interim report, released in February, described a dire outlook for global warming and recommended developed nations pursue emissions cuts of 70-90 per cent by 2050.
According to the authors, in light of this scenario, developed countries would have to make emissions cuts by 2020 at or above the top end of the range being discussed in global talks.
"Without all major emitters binding themselves to economy-wide targets or policies, given rapid emissions growth, the prospects for the global climate change mitigation effort are bleak," the report said.
