The fourth iteration of the Transatlantic Transportation Decarbonization Summit (TTDS) brings us to London and to the United Kingdom. As ever, this one-of-a-kind, intimate conference gathers government, industry, and thought leaders to accelerate one of the most important mechanisms for climate change mitigation: the electrification of all on-road vehicles. 2030 marks a critical target for many zero-emission transportation policies, and 2025 leaves us a mere five-year timeline to reach them.
Major markets across North America and Europe must accelerate the transition by championing leading-edge technologies and strategies. With input from six key government advisors, California, Canada, Germany, the European Commission, the United Kingdom, and the United States, TTDS25 returns as the paramount event to nurture deep conversation, relationship building, and ultimately problem-solving collaborations.
Hosted by the International Council on Clean Transportation, TTDS25 will take place at De Vere Latimer Estate in Chesham, UK from Tuesday, June 10th, through Friday, June 13th. TTDS25 is an invite-only event. Registration instructions have been sent out via email.
