Greta Thunburg has said humans should not “give up hope” of combating climate change, after criticised the British government for not taking meaningful action.

Youth activists on Tuesday challenged world leaders to ’empty words and promises’ when they called for measures – and money – to help combat global warming ahead of a crucial U.N. climate summit.

During her speech, the climate activist, 18, also cited some of Prime Minister Boris Johnson’s statements on Britain’s response to climate change.

“We must find a smooth transition towards a low carbon economy. There is no Planet B,”Greta Thunberg

“We must find a smooth transition towards a low carbon economy. There is no Planet B,” says Thunberg, alluding to a speech by French president Emmanuel Macron.

Mr Johnson has said he will push for action on coal, climate change, automobiles and trees at the Copenhagen Climate conference in Glasgow in November.

Some 400 youth activists from nearly 200 countries gathered in Milan will publish a joint statement later this week, the prelude for the Euro 26 round in Glasgow.

Cop26 president Alok Sharma was at the youth event and is headed to the ministerial conference for the session.

Several other countries have also announced plans to reduce the greenhouse gases they produce within the Paris Accord, a pledge made by nations to combat climate change.
