How to calculate the carbon footprint

Who would have thought ten years ago that this is one of the most frequently asked questions we answer every day… How do you calculate your carbon footprint? A question we love to answer. The starting point is to include all Greenhouse Gases (GHG), including CO2. There are different measurement methodologies. However, the most widely used standards in the world are set by the Green Gas Protocol (GHG).

According to the GHG Protocol, a simplified carbon footprint is calculated by multiplying an activity figure by an emission factor.


For example, for electricity consumption*:

(350 kWh) x (0,41kgCO2/kWh) = 143,5 kg CO2

* The emission factor corresponds to traders without guarantee of origin. Miteco Publication 2018. Source: CNMC.

At GreeMko, we follow the GHG. In addition, our tool incorporates all the parameters of the Global Reporting Initiative (GRI). Activity data is obtained automatically from electricity, natural gas, diesel or petrol bills. Emission factors are obtained from official sources; in our case: the International Energy Agency (IEA) and the Ministry for Ecological Transition and Demographic Challenge (Miteco).

Greenhouse gas emissions are classified by scope. In this table, we point out the measurement capability of the GreeMko software.

When considering how to calculate the carbon footprint, companies often start by measuring scopes 1 and 2. Scope 3 is the most difficult to calculate. But with the GreeMko application, it can be measured very quickly and easily.

What other elements of environmental impact does GreeMko measure? Water consumption, raw material consumption, energy consumption, waste generation and others in line with international standards.
