Professor Peter Newell
Academic Peter Newell made waves in the global media recently with a report describing how the wealthy have a disproportionate effect on climate change, and a duty to change their travel, business and leisure habits. As COP26 kicks off in Glasgow, he speaks to LUX about how moral duties increase with net worth
LUX: How do you define ?unnecessary travel?"

Peter Newell: It is not for us as individuals to work out what counts as unnecessary travel: governments, cities and businesses can send clear signals about which travel is critical and which is largely unnecessary. Wealthy employers can set sustainable travel policies for their companies. But all of us can also exercise responsible self-restraint. Addressing poverty and social inequality means that carbon will inevitably and justifiably increase for some people, especially, but not exclusively, in the Global South. To still live within tightening carbon budgets means cutting back on luxury emissions, including where travel to conferences and meetings is no longer necessary when virtual platforms can replace that need, as well as reducing frequent flying for holidays. It is worth remembering that just one per cent of people cause half of global aviation emissions.
