Mitigating climate change through reductions in greenhouse gas emissions: is it possible to limit global warming to no more than 1.5C?
The Parties to the United Nations Framework Convention on Climate Change (UNFCCC) are contemplating a range of goals for limiting the rise in global average temperature that is resulting from rising concentrations of greenhouse gases in the atmosphere. Whatever temperature goal is eventually agreed by the Parties, its achievement will depend on the extent to which global emissions of greenhouse gases can be limited and reduced. This study explores a variety of potential paths for annual global emissions of greenhouse gases which would offer a reasonable chance of limiting a rise in global average temperature to no more than 1.5
