Two electric car charging companies are announcing plans to build 3.5mn plug-in spots in the US and Europe by 2025 in an effort to accelerate the adoption of clean vehicles, according to Bloomberg. California-based ChargePoint Inc will deliver 2.5mn places to charge and EVBox will install 1mn new fast and regular chargers, according to a statement on Friday by The Climate Group, which helps develop zero-emission programmes. The new charging stations will support 37mn electric vehicles that are forecast to be on the road globally by 2025, driving a combined 384bn electric miles per year. The announcement was made during the Global Climate Action Summit in San Francisco.
