Climate change has grabbed the attention of industry all over the world and yet there is no single definition or measure for it, leave alone a road map by the industry to contain it.
The issues pertaining to definition range form inclusion of CO2 only to other Green House Gases like methane as well. Questions are also raised whether GHGs that do not include molecules of carbon be included. Should emissions not having GHGs also be included in the definition? These are the gases that still have hazardous impact on the environment e.g. CO – which has the potential of being converted into CO2 in the atmosphere.
The question of gases that can be included in the carbon footprint is only one dimension of the problem of defining and measuring. Other dimension relates to the scope – it is a question of where the boundary lies. Do we consider only the direct on-site emissions or we also consider indirect emissions because of upstream activities in the chain? How the life cycle impact of processes and products be measured reliably eliminating the chances of omissions and double counting.
