Every product (a good or service) has a carbon footprint that reflects the amount of greenhouse gas emissions during the life cycle of a product.

Life Cycle Assessment (LCA) is the most common method used to calculate the carbon footprint. It is important to realise that No footprint calculation is ever perfect. They are always ’best estimates’ of the emissions from a particular snapshot in time, based on the best available data. 

There are three ways greenhouse gases are emitted through the use or consumption of energy linked to products and services. These are referred to as scopes;
