Carbon footprint refers to the quantity of greenhouse gases emitted into the atmosphere during the life cycle of any product or activity and is expressed in terms of carbon dioxide equivalents (CO2-e). For food items, the major activities included are production phase (cultivation of crops, fruits, etc. rearing of animals), processing, distribution, sales and sometimes to consumption.
Carbon footprints basically represent the greenhouse gas intensity of any activity and hence indicates contribution of any activity to global warming. Originally this term was derived from the concept of ‘Ecological Footprint’ and exclusively was concerned with carbon dioxide. But, it has evolved with a potential role as greenhouse gas intensity indicator. Therefore, now days, carbon footprints considers all significant greenhouse gases including carbon dioxide.
What happens when 27 high schools across Norway participate in a climate emissions challenge? Over 6000 participants together saved 273,471 kg CO2e in just 3 weeks. And that’s equivalent to flying 27 times around the earth. In fact, if all Norwegians copied the top 20 classes in the challenge, the country would save 40% of its total... Read more
