China's carbon dioxide emissions rose 10.4 percent in 2010 compared with the previous year, as global emissions rose at their fastest rate for more than four decades, data released by BP on Wednesday showed.
"All forms of energy grew strongly (last year), with growth in fossil fuels suggesting that global CO2 emissions from energy use grew at the fastest rate since 1969," energy major BP's annual Statistical Review of World Energy said.
The rapid growth is happening as U.N. talks look unlikely to agree on a legally binding deal to curb emissions and fight climate change before the existing Kyoto Protocol expires in 2012.
Global carbon dioxide emissions are widely seen as a major factor responsible for an increase in world temperatures.
They grew 5.8 percent last year to 33.16 billion tonnes, as countries rebounded from economic recession, BP said. China's emissions accounted for 8.33 billion tonnes.
The International Energy Agency estimated last month that global CO2 emissions rose by 5.9 percent to 30.6 billion tonnes in 2010, mainly driven by booming coal-reliant emerging economies.
BP data showed that China accounted for a quarter of global emissions. The United States was the second largest emitter, showing a 4.1 percent rise in emissions last year to 6.14 billion tonnes.
Chinese emissions have grown strongly in the past decade as the country built many new coal plants to power its economic growth. Its energy consumption swelled by over 11 percent last year, compared to global growth of 5.6 percent.
Global coal consumption increased by 7.6 percent last year in its fastest growth since 2003, as industries began to recover from the global economic downturn.
Coal now accounts for 29.6 percent of global energy consumption, up from 25.6 percent 10 years ago, BP said.
Chinese coal use grew by 10.1 percent last year. It consumed 48.2 percent of the world's coal, slightly up from around 47 percent in 2009.
Meanwhile, global coal production rose by 6.3 percent, with China up 9 percent, accounting for two thirds of global growth.
Elsewhere, coal production grew robustly in the United States and Asia but fell in the European Union, explaining the relative strength of coal prices in Europe, BP said.
In terms of cleaner energy, global hydroelectric and nuclear output each experienced their strongest rises since 2004.
Hydroelectric output grew by 5.3 percent, with China accounting for more than 60 percent of global growth due to new capacity coming online and wet weather.
Worldwide nuclear output grew by 2 percent last year, with OECD countries accounting for three quarters of that increase.
French nuclear output rose 4.4 percent, representing the largest increase in the world.
Other renewable sources also grew. Global biofuels production was up 13.8 percent at 240,000 barrels a day.
The United States and Brazil drove most of that growth, rising 17 percent and 11.5 percent respectively.
Renewable power generation grew by 15.5 percent, driven by robust growth in wind energy, which was up 22.7 percent.
"The increase in wind energy in turn was driven by China and the U.S., which together accounted for nearly 70 percent of global growth," the report said.
"These forms of renewable energy accounted for 1.8 percent of global energy consumption, up from 0.6 percent in 2000." (Editing by Anthony Barker)
