VW Group CEO Herbert Diess, said: "Whether the earth warms by 1.5 or 2 degrees Celsius by 2050 has a major impact on developments such as species extinction, droughts and rising sea levels. The Volkswagen Group is taking its responsibility to protect the world for future generations. That is why we are sharpening our own emissions reduction targets in production after less than two years. We are pleased that the Science Based Targets initiative recognises this."
