Greta Thunberg was fined for not leaving a climate protest in the Swedish port of Malmo last month when police told her to.

The 20-year-old protester didn’t agree with the accusation. During a short hearing, she said, “What I did was right.”

AFP says that a court in Malmo found her guilty and gave her a fine of 2,500 Swedish krona ($240 or £187).

Thunberg was one of the protesters who stopped the road in Malmo harbor for oil trucks.

She was charged because she didn’t leave when the cops told her to.

She told the court, “I believe we are in an emergency that threatens life, health, and property.” She also said that “many people” were in danger.

“It’s true that I was there that day, and it’s true that I got an order that I didn’t follow,” she said, “but I want to deny the crime.”

In June, a group of environmental activists called Ta tillbaka framtiden (Reclaim the Future) held a rally to protest the use of fossil fuels. They tried to stop the entrance and exit to the Malmo harbor.

“We don’t want to just stand by and do nothing, so we’re going to physically stop the fossil fuel infrastructure.” “We are taking back the future,” Thunberg wrote at the time in an Instagram post.

Reclaim the Future says it is still ready to take on the business.

“If the court wants to see what we did as a crime, it can,” Irma Kjellstrom, a spokesperson for the group, told the AFP news agency. “But we know we have the right to live, and the fossil fuels industry is getting in the way of that.”

Greenhouse gases have been put into the air by burning fossil fuels and other things. The world is about 1.1C warmer now than it was in the late 1800s.

The fossil fuels business has been a target of climate activists. Most people in the oil and gas business say that production must keep going to meet the world’s energy needs.
