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 of hydrogen by steam reforming and the water gas shift reaction in ammonia production. These processes begin with the reaction of water and natural gas (mainly methane). This is a major source of food-grade carbon dioxide for use in carbonation of beer and soft drinks, and is also used for stunning animals such as poultry. In the summer of 2018 a shortage of carbon dioxide for these purposes arose in Europe due to the temporary shut-down of several ammonia plants for maintenance. Acids liberate from most metal carbonates. Consequently, it may be obtained directly from natural carbon dioxide springs, where
