G20: Boris Johnson and Justin Trudeau discuss climate issues at conference

Boris Johnson and Justin Trudeau sat down together in Rome during the two-day meeting of 20 major economies, where the main topic of discussion will be climate change.

It is the first time in two years that most leaders of the G20 have felt able to hold face-to-face discussions as the COVID-19 pandemic starts to recede in many countries.

The health crisis and economic recovery feature strongly on the agenda, but the most difficult debate will centre on how far the leaders want to go in cutting greenhouse gases and in helping poorer nations confront global warming.
