A report from the Netherlands Environmental Assessment Agency out this week (Trends in global CO2 emissions) shows that while actual global emissions of carbon dioxide (CO2) reached a new record of 34.5 billion tonnes in 2012, the increase in global CO2 emissions in that year slowed down to 1.1%. This, said the agency, was less than half the average annual increase of 2.9% over the last decade.
“This is remarkable, as the global economy grew by 3.5%. This development signals a shift towards less fossil-fuel-intensive activities, more use of renewable energy and increased energy saving. Increases in fossil-fuel consumption in 2012 were 2.2% for natural gas, 0.9% for oil products, and 0.6% for coal.“The share of the ‘new’ renewable energy sources solar, wind and biofuel increased at an accelerating speed: from 1992 it took 15 years for the share to double from 0.5% to 1.1%, but only 6 more years to do so again, to 2.4% by 2012.”
The report raised the possibility of a more permanent slowdown in emissions:
“The small increase in emissions of 1.1% in 2012 (including a downward correction of 0.3% for it being a leap year) may be the first sign of a more permanent slowdown in the increase in global CO2 emissions, and ultimately of declining global emissions, if (a) China achieves its own target for a maximum level of energy consumption by 2015 and its shift to gas with a natural gas share of 10% by 2020; (b) the United States continues a shift in its energy mix towards more gas and renewable energy; and (c) in the European Union, Member States agree on restoring the effectiveness of the EU Emissions Trading System to further reduce actual emissions.”
