Brief description of the data offering

The NEC provides a simple answer to a complex question: to what extent does a company's activity contribute to the ecological transition? It is a holistic metric (Climate – Biodiversity – Resources), spread over a 200-scoring scale:

  • From -100% for activities that are the most destructive of natural capital
  • To +100% for activities that are the least impactful
  • With 0%, corresponding to the current global average for each activity analysed

It is based on a lifecycle analysis approach, and provides data for all economic sectors, enabling cross-sectorial analysis.

It is applicable cross-assets (listed, non-listed, bonds, real assets, …), on a worldwide basis.
