This sub-metric is used to evaluate the metric : ""1.4 GHG emissions intensity""
GHG emissions intensity is a key indicator when monitoring the real relative impact of a company's carbon footprint. We therefore value companies including this indicator in their reporting, albeit with different denominators to the one we have chosen.
The measure we have selected to assess the intensity of GHG emissions in the retail sector in a homogeneous way is TnCO2eq per m2.
This question is intended to reward the most efficient and least polluting companies in terms of emissions, taking into account the "Greenhouse Gas (GHG) Emissions Intensity GRI 305-4" indicator of the Global Reporting Initiative (GRI). This indicator, which measures the intensity ratio of scope 1 and 2 emissions, allows the degree of air pollution of an entity to be assessed and compared homogeneously in relation to a unit of activity, production, surface area or any other specific parameter, thus helping to contextualise the efficiency of the organisation, including in relation to other organisations. In our methodology for supermarkets we use as a specific parameter (denominator) the sales area in m2 as it is the most representative variable used in the sector.
In case the company does not directly publish its emissions intensity or does so using another parameter, the data will be collected from its absolute Scope 1 and 2 emissions and its total sales area in m2 :
Emission intensity = Total Scope 1 and 2 emissions in TnCo2 eq. / Sales area in m2
The sales area figure should be the same as the one used by the company for its emissions computation, so if the company does not publish it in its reports, we will calculate it from another published ratio (electricity, waste or water per m2).
So for example, if their total electricity consumption is 1000,000 kWh and they publish a consumption ratio of 100 kWh per m2, the company's surface area would be 1000,000 / 100 = 10,000 m2.
In case the company does not publish any other ratio based on its commercial surface we will use the one published by reference sources such as Alimarket, InfoRetail, Nielsen, Kantar, IRI, etc. If this is the case, the source and the measurement method should be the same for the same company and years of evaluation.
We will assign a ""YES"" if :
- The company's scope 1 and 2 emissions intensity is less than 500kg CO2-eq per m2 of commercial floor area per year.
