Marvin Rees flew more than 4,600 miles to give a 14-minute Ted talk about how mayors play an important role in tackling climate change.
The Mayor of Bristol gave a talk in April at a Ted conference held in Canada, and this week the talk was made available for the public to watch online.
He spoke about how city mayors are “leading beyond their authority” and influencing global policy on cutting carbon emissions, and he called for more investment into cities.
