Seumas Kerr CBE talks to Helen Clarkson, CEO of the The Climate Group, about the race to net-zero carbon. Topics for discussion include obstacles to the EV100 scheme, which brings together organisations committed to accelerating the transition to electric vehicles by 2030, the UK’s opportunities to demonstrate genuine global leadership in the fight against climate change, and the notion of an ‘historical carbon debt’ owed by the early industrialisers of the western hemisphere to the global south.
