Greta Thunberg tells EU to set emissions reduction goals for 2020

The EU's executive unveiled a planned climate law to reduce net greenhouse gas emissions to zero by 2050.

"We cannot just have goals for 2030 or 2050. We also need them for 2020 because right now, if high emissions continue like today's business as usual, then the remaining budget will be gone before we will even have a chance to deliver on those targets," Thunberg said.

Thunberg began missing school in 2018 to sit outside the Swedish parliament in a solitary protest.

Since then, the 17-year-old activist has galvanized a global movement of young people, inspiring millions to take to the streets to demand that world leaders act urgently to tackle the climate crisis.
