Global Carbon Budget (http://www.globalcarbonproject.org/carbonbudget/)
Global carbon dioxide emissions from burning fossil fuels and cement production continue to grow at a high pace
* Global CO2 emissions from burning fossil fuel and cement production grew 2.3 per cent to a record high of 36 billion tonnes CO2 in 2013. Emissions from deforestation remain low in comparison, at 3.3 billion tonnes CO2 in 2013, accounting for 8% of total emissions.
* Fossil fuel CO2 emissions are projected to increase 2.5% in 2014, bringing the total CO2 emissions from all sources above 40 billion tonnes CO2.
* Fossil fuel emissions in the last ten years grew at 2.5% per year on average, lower than the growth rate in the 2000s (3.3%) but higher than the growth rate in the 1990s (1%). The declining growth rate in recent years is associated with lower GDP growth compared to the 2000s, particularly in China.
* Fossil fuel emissions track the high end of emissions scenarios used by the IPCC to project climate change, due to smaller improvements in carbon intensity of GDP than expected in most scenarios, and continued GDP growth.
* Given current projection of the World GDP, emissions are expected to grow further in the absence of more stringent mitigation.
* The largest emitters were China, USA, EU28 and India, together accounting for 58% of the global emissions and 80% of the growth in 2013 (top 20 emitters provided below). Key results for the top four emitters are:
- Chinese emissions grew at 4.2%, the lowest level since the 2007-2008 because of weaker economic growth and improvements in the carbon intensity of the economy.
- USA emission increased 2.9% in 2013 due to a rebound in coal consumption, reversing the declining trend in emissions since 2008.
- Indian emissions grew at 5.1% caused by robust economic growth and an increase in the carbon intensity of the economy.
- EU28 emissions decreased 1.8% on the back of a weak economy and emission decreases in some countries offsetting a return to coal led by Poland, Germany, Finland.
