Swedish climate activist Greta Thunberg was fined today after she was found guilty for disobeying a police order to leave a demonstration in Malmö last month, the district court of that city announced.

The 20-year-old Thunbergwho became the “face” of young climate activists around the world after organizing weekly protests outside the Swedish parliament, admitted she disobeyed police orders but pleaded not guilty, saying she was acting out of an emergency.

“It is absurd that those who act on the basis of science should pay the price,” he told reporters outside court.

On June 19, Thunberg and other activists of the organization Reclaim the Future they blocked a road where oil tanker trucks were passing. The police asked them to leave, but they did not obey.

Earlier, in court, Greta Thunberg said her actions were justified. “I believe we are in an emergency that threatens life, health and property. Countless people and communities are at risk, in the short and long term,” he insisted.

The court ordered her to pay a fine of 1,500 Swedish kroner (about 140 euros) and pay another 1,000 kroner to a fund for victims of crime. This fine is proportional to her declared income.

In Sweden disobeying police orders is punishable by up to six months in prison.

Despite her conviction, a few hours later Thunberg helped organize another similar rally in the port of Malmö.
