Emissions Gap Report 2014

In order to limit the global temperature rise to a maximum of two degrees Celsius and avoid the worst impacts of climate change, global carbon neutrality must be attained between 2055 and 2070. This means that carbon dioxide emissions must hit net zero by this period at the latest. If climate change is to be kept to a manageable level, the international community can only produce another approximately 1,000 gigatonnes of carbon dioxide in total. Since the late 19th century, however, humankind has produced nearly double this amount of CO2 emissions (1,900 gigatonnes), thereby releasing nearly two thirds of the maximum permissible amount into the atmosphere. These are two of the key statements in the fifth Emissions Gap Report, which was published by the United Nations Environment Programme (UNEP) with funding from the International Climate Initiative (IKI).

The Report analyses whether the pledges made by nations regarding climate change mitigation will suffice to reach the agreed two-degree target. It was prepared by 38 leading scientists from 22 research groups across 14 countries. Published ahead of the climate change negotiations in Peru, the analysis clearly shows what challenges and opportunities lie ahead on the road to reaching the set target.
