About the companies

We used the following methodology to identify the keystone companies:

  1. Target the most impactful companies using for example, the CDP Investor Research Autos report for publicly listed companies and high production privately owned companies.
  2. Research and data gathering: in terms of corporate structures – companies that are subsidiaries or have been merged or incorporated into others in recent years have been taken into consideration. The emphasis is put on light duty vehicles. Data is gathered on vehicle production, market capitalization and revenue.
  3. Analysis: all companies are then ranked through an ‘impact index’ that equally weights vehicle production, market capitalization and revenue. The first twenty five companies in the ‘impact index’ are considered in scope as a keystone company with direct impact on the transformation of the sector.
