An environmental score to guide action
The NEC metric evaluates economic activities based on their impact on the environment. It is a relative measure that can be applied across sectors and has a high level of granularity. The NEC metric places companies on a scale from -100% to +100% which enables economic actors to identify companies that have a stronger impact on the environment, “destructors” which are between -100% and 0%, as well as companies that have less impact on the environment, “contributors” which are between 0% and +100%. This scale enables cross-sectoral comparison with a high level of granularity.
Beef | -100%
The impact comes mainly from deforestation (soybean production for livestock), methane production (enteric fermentation), fertilizer use and high water consumption.
Beef
Cotton | -24%
The impact comes from the very high water consumption necessary for cotton production. Cotton is also one of the biggest consumers of pesticides, impacting biodiversity and polluting the soil.
Cotton
Aluminium | -40%
The production of aluminum requires large amounts of electricity and water. The extraction of bauxite in open-pit mines severely degrades local biodiversity and pollutes the soil.
Aluminium
Milk | +17%
The impact comes mainly from deforestation (soybean production for livestock), methane production (enteric fermentation), fertilizer use and high water consumption.
Milk
Wood structure | +43%
Wood, which is sustainably managed, is a renewable material with a lower carbon footprint than the main solutions for building load-bearing structures.
Wood structure
Electric train | +100%
The train is one of the most efficient solutions for moving large numbers of people or goods over long distances. GHG (Greenhouse Gas) emissions and associated air pollution are low compared to other alternatives.
