The episode discusses the strategies of European car manufacturers to address the stringent EU CO2 emission regulations set for 2025. Due to heavy fines anticipated for non-compliance with the limits, companies are opting for "pooling," which involves purchasing carbon credits from electric vehicle producers like Tesla and Polestar. This solution, although contested for its potential regulatory evasion, is seen by car manufacturers as more convenient than drastic price cuts on electric vehicles, allowing them to balance compliance with sustainability. European institutions are aware of this situation, and the pressure for a genuine ecological transition in the automotive sector is high.
