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 used by almost half a million young people at nightspots, festivals, and parties. The legality of that use varies greatly from country to country, and even from city to city in some countries. The major safety hazards of nitrous oxide come from the fact that it is a compressed liquefied gas, an asphyxiation risk, and a dissociative anaesthetic. While relatively non-toxic, nitrous oxide has a number of recognized ill effects on human health, whether through breathing it in or by contact of the liquid with skin or eyes. Nitrous oxide is a significant occupational hazard for surgeons, dentists, and nurses.
