There's no doubt that environmental activist Greta Thunberg is one of the most politically influential teenagers ever. Just a few years after she protested public apathy over climate change by forgoing school, she's managed to kickstart an entire social movement, been named TIME's Person of the Year for 2019, and nominated twice for the Nobel Peace Prize.

However, it seems as though she's still not happy with the progress made by politicians after she was spotted looking extremely unimpressed by the European Union's new climate laws.

Per British tabloid newspaper The Daily Mail, the 17-year-old girl was the guest of honor at a meeting of the European Commission in Brussels. New legislation has just been enacted following a summit in June, which is aimed at decarbonizing the European economy.

This legislation will commit the 27-member bloc to zero greenhouse gas emissions by 2050. Not only this, but the change in the law will also give the European Union powers to impose new emission targets.

However, an unimpressed Thunberg seemed to believe it was too little too late and called the new law a "surrender." She was pictured looking pretty irate at the meeting by press photographers and later condemned the EU's climate plans as insufficient.

In an open letter, Thunberg wrote: "Net zero emissions by 2050 for the EU equals surrender. It means giving up. We don't just need goals for just 2030 or 2050. We, above all, need them for 2020 and every following month and year to come."

Thunberg later told the MEP committee: "The European Union must stop 'pretending that you can be a climate leader and still go on building and subsidizing new fossil fuel infrastructure."

This comes just a few weeks after Thunberg took to the stage at the World Economic Forum, claiming that world leaders are running out of time to deal with the issue of climate change.
