Footnotes: Shale Gas Analysis for Committee on Climate Change
1. The modelling uses a global CO 2 budget that allows for emissions of non- CO2 greenhouse gases in limiting warming to the specified levels. However, additional unconventional gas production that is forced in does not assume any associated methane emissions. . Effectively the analysis assumes that any methane from the fossil fuel energy system is the same in the shale and non-shale cases. The fugitive methane emissions associated with shale gas extraction represents an area of active research and analysis. Possible global warming implications of these emissions are modelled in detail in reference .
