Greta Thunberg warns politicians who fail to tackle climate change at an EU conference

BRUSSELS: Greta Thunberg, the 16-year-old Swedish climate activist who has inspired pupils worldwide to boycott classes, urged the European Union on Thursday to double its ambition for greenhouse gas cuts.

At an EU conference, Thunberg warned that politicians who fail to tackle climate change will be "remembered as the greatest villains of all time" for leading the world to disaster.

"If the EU is to make its fair contribution to staying within the (Paris climate deal) carbon budget for a two-degree limit, it means a minimum of 80 percent reduction by 2030," Thunberg told the conference, receiving warm applause.

"And that includes aviation and shipping," she said in a ten-minute speech before European Commission chief Jean-Claude Juncker and EU civil society. "So around twice as ambitious as the current proposal."

Under the 2015 Paris deal to limit global warming to well below 2 degrees Celsius, the 28-nation EU has pledged to cut greenhouse gas emissions by at least 40 per cent by 2030, compared to 1990.

EU officials are now talking of increasing the figure to 45 per cent.

The young Swede alluded to warnings from the UN's Intergovernmental Panel for Climate Change (IPCC) that warming is on track toward an unliveable 3C or 4C rise, and avoiding global chaos will require a major transformation.

She said there was still about a decade to act to make such a transformation.

She hit global headlines with her speech in December at a UN climate meeting in Poland and has received support from climate activists.

Every Friday since August last year, Thunberg has staked out a spot in front of the parliament building in Stockholm, demanding that her government step up the fight against climate change.

In the last six months, tens of thousands of high school students -- in Sydney, Brussels, Berlin, The Hague, London and other cities have followed suit.
