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
Nitrous oxide engine alcohol, diesel fuel, propane, or CNG to produce carbon dioxide and water vapor, along with heat, which causes the former two products of combustion to expand and exert pressure on pistons, driving the engine. Nitrous oxide is stored as a liquid in tanks, but is a gas under atmospheric conditions. When injected as a liquid into an inlet manifold, the vaporization and expansion causes a reduction in air/fuel charge temperature with an associated increase in density, thereby increasing the cylinder's volumetric efficiency. As the decomposition of NO into oxygen and nitrogen gas is exothermic and thus contributes to a higher
