Global carbon dioxide emissions grew 1.4% in the last year, reaching 32.5 gigatonnes after three years of remaining flat. That's the sobering news from The Global Energy and CO2 Status Report issued 2 weeks ago by the International Energy Agency. Global energy demand rose by 2.1%, with demand for renewables growing the fastest. Global energy demand was led by Asia, with China and India together representing over 40% of the increase.
Global energy efficiency improved by just 1.7%, compared with a 2.3% average reduction in each of the last few years. Energy-related CO2 emissions grew by 460 million tonnes, the equivalent of 170 million cars. In total, Asia accounted for two-thirds of the global increase in CO2 emissions.
The US, UK, Mexico, and Japan all experienced declines in CO2 emissions, led by the US' push for renewable sources of energy. China and the US accounted for 50% of the increase in renewables-based electricity generation.
