- The EU emitted close to 5 billion tonnes (Gt) of CO2-equivalent emissions in 2008. It contributes today around 12 % of annual global anthropogenic direct greenhouse gas emissions. The EU is making good progress towards achieving its emission reduction targets. A rapid, sustained and effective transition to a low carbon economy is necessary to mitigate climate change and to meet global greenhouse gas emission targets.
