Currently we are hearing a lot of companies declaring their target to be carbon neutral and even some countries declaring the same. To be able to achieve carbon neutral, one has to understand your carbon footprint.
A carbon footprint is the quantity of greenhouse gas (GHG) emissions that were produced as a result of one’s activities. Carbon footprints are usually measured annually taking into account the impact of all the activities over the course of a year. The unit for a carbon footprint is metric tonnes of carbon dioxide equivalent (tCO2e). Carbon dioxide is the most common GHG emitted by human activities, hence CO2e unit is used to takes into account all other GHGs (such as methane and nitrous oxide), by putting them in terms of carbon dioxide by multiplying each GHGs global warming potentials (GWP).
To be carbon neutral, one has to manage and reduce the GHG emissions related to your activities. This can be done by changing your activities to be greener such as being energy efficient, using renewable energy, managing your waste and so on; as well as off-setting any carbon emissions that you cannot easily remove.
Dear Matt, thanks for the info. Does carbon footprint calculation also includes all the travelling activities by staff ? If yes, then how about the mode of travel of the staff is different, like air travel, train or car; how do i calculate the carbon footprint impact for my company ? Appreciate some input from you. Thanks.
Good question Shaun. The carbon footprint for commuting to work and all travelling activities related to work will need to be taken into account too. This is normally considered as Scope 3 emission in GHG Protocol for carbon report. Depend on type or mode of transport used, each will have their own carbon emission factor that can be used for different mode of transport.
