China's carbon emissions may have dropped in 2014

China’s emissions of carbon dioxide may have fallen 2% in 2014 according to an estimate based on preliminary demand data from the country’s national bureau of statistics, Bloomberg reported. The estimate from Bloomberg came as the International Energy Agency announced global carbon emissions from the energy sector were unchanged last year. China’s coal consumption, the country’s greatest driver of CO2 emissions, fell 2.9% in 2014 from the previous year, according to an analyst with research firm North Square Blue Oak. China’s energy consumption growth also weakened to 3.8% last year as its economy expanded at its slowest pace since 1990.
