Climate footprint Climate footprint The term climate footprint has emerged from the field of carbon footprinting, and refers to a measure of the full set of greenhouse gases (GHGs) controlled under the Kyoto Protocol. A climate footprint is a more comprehensive measure of anthropogenic impact upon the climate than a carbon footprint, but is also more costly and labour-intensive to calculate. A climate footprint is a measure of the total amount of carbon dioxide (CO), methane (CH), nitrous oxide (NO), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs) and sulphur hexafluoride (SF) emissions of a defined population, system or activity, considering all relevant sources, sinks and
Carbon dioxide clathrate Type I clathrate for the first time by von Stackelberg & Muller (1954). On Earth, CO hydrate is mostly of academic interest. Tim Collett of the United States Geological Survey (USGS) proposed pumping carbon dioxide into subsurface methane clathrates, thereby releasing the methane and storing the carbon dioxide (Michael Marshall, 2009). As of 2009, ConocoPhillips is working on a trial on the Alaska North Slope with the US Department of Energy to release methane in this way, (ConocoPhilips, January 2010, New Scientist, no. 2714, p. 33). At first glance, it seems that the thermodynamic conditions there favor the existence of
