Boris Johnson has warned world leaders there are “no compelling excuses” for failing to tackle climate change, according to the BBC.
Speaking at the close of the G20 summit in Rome, he said some progress was made in the past few days – but there was still a “huge way” to go.
World leaders were meeting in Rome to discuss what can be done to keep global warming in check, ahead of the COP26 climate summit in Glasgow.
Mr Johnson added immediate action was needed to halve emissions by 2030.
In Rome, the leaders of the 19 countries and the European Union, which form the G20 group of major economies, agreed to pursue efforts to limit global warming with “meaningful and effective actions”.
The prime minister said: “There are no compelling excuses for our procrastination.
“Not only have we acknowledged the problem, we have already seen first hand the devastation that climate change causes – heatwaves and droughts to wildfires and hurricanes.”
Referring to a treaty on climate change that came from a previous COP summit in 2015, he said: “If we don’t act now, the Paris Agreement will be looked at in the future, not as the moment that humanity opened its eyes to the problem but the moment we flinched and turned away.”
