Global CO2 emissions reach 36 billion tonnes this year, driven by China and coal

Emissions of carbon dioxide from fossil fuels and cement production reached a new high in 2012, rising 2.2 per cent over 2011 due chiefly to an increase in coal-burning China, scientists said Tuesday.

Output of CO2 from these sources was a record 35 billion tonnes, 58 per cent above 1990, the benchmark year for calculating greenhouse-gas levels, according to the annual analysis by an international group called the Global Carbon Project.

“Based on estimates of economic activity in 2013, emissions are set to rise 2.1 per cent in 2013 to reach 36 billion tonnes of CO2,” it said in a report coinciding with the UN climate talks in Warsaw.

The 2012 and 2013 rates are slightly below the average growth of 2.7 per cent annually over the last 10 years.

Carbin dioxide is the principal greenhouse gas, and fossil fuels -- coal, oil and gas -- along with cement production account for nearly all its man-made emissions. Around four billion tonnes of CO2 come from other sources, including changes to land use, the report said.

China, the world’s number one carbon emitter, accounted for 70 per cent of the global increase in 2012, it said.

Chinese emissions grew 5.9 per cent in 2012, lower than the average of 7.9 per cent per year over the past decade.

Consumption from renewable sources and hydropower in China grew by a quarter in 2012.

But that growth came from a low baseline, and was more than offset by an increase of 6.4 per cent in coal, which has a higher baseline. Coal accounted for 68 per cent of Chinese energy consumption in 2012.

Other significant CO2 increases occurred in Japan, with 6.9 per cent, and Germany, with 1.8 per cent, pushed by a switch to coal to offset dependence on nuclear.

Indian emissions increased by a whopping 7.7 per cent, with those from coal growing 10.2 per cent.

Emissions by the 28-nation European Union fell by 1.3 per cent, but emissions from coal grew 3 per cent.

 In the United States, the world’s No. 2 emitter, CO2 emissions fell by 3.7 per cent in 2012, with those from coal decreasing by 12 per cent as the country turned to cleaner shale gas.

“If US emissions continue to decline as in the last five years, then China will emit more than the US on a per capita basis in the period 2020-2025,” said Glen Peters, with Norway’s Centre for International Climate and Environmental Research - Oslo (CICERO), who contributed to the report.

Per capita emissions are one of the biggest issues in the climate-change arena.

Developing countries, which include China, say rich nations should bear most of the burden for warming, as they initiated the problem and their emissions per person are much higher than those of poorer economies.

But China’s per capita emissions are rising fast because of its reliance on coal, which less energy-efficient than other fuels, the report said.

Its emissions are roughly level-pegged with those of the EU, at seven tonnes of CO2 per head.

“China has had rapid economic growth in the last decades, bringing lasting benefits to its citizens, but this has come at a great cost to the environment,” said Peters.

“The conventional view is that China still lags behind developed countries, but China is actually comparable to many developed countries in terms of per capita CO2 emissions.”

The study involved 49 authors from 10 countries.

In May, levels of CO2 in the atmosphere briefly exceeded 400 parts per million for the first time since measurements began at the Mauna Loa Observatory on Hawaii.

Some experts fear the world is on track for double the UN target of two degrees Celsius over pre-industrial times - a recipe for worse drought, flood, storm and rising seas.

At a meeting of African leaders on 24 June 2010 in Chad, the World Bank Global Environment Facility announced to devote 96 million Euros to the "Great Green Wall of the Sahara" initiative: a barrier of trees 7,000kilometer long and 15kilometer wide, which will be planted across 11 African countries, from Senegal to Djibouti. This Green Wall will have to slow down wind erosion and enhance rainwater infiltration. It would also act as a massive sink to soak up harmful carbon emissions that are a prime factor behind global warming. We propose to develop this green wall with regenerating Paulownia/Kiri and never dying Moringa Oleifera trees able to annually sink 75 tCO2/ha net anthropogenic GHG removals. So the Green Wall of Africa can annually sink 787.5 million ton CO2 with a compensation value of $75/ton. China built its Great Wall in the past, maybe China can adopt the Green Wall for the future and fund it with carbon credit compensations. Magnificent goodwill and enormous economic injection to accelerate the sustainable development of Africa.
