The Hague District Court ordered Shell to cut its carbon emissions by 45% by 2030, compared to 2019 levels, in a landmark case brought by climate activists.

Climate activist Greta Thunberg was detained twice by police at a demonstration in the Netherlands, after she and a group of marchers blocked a main road to protest against fossil fuel subsidies. Thunberg was initially detained by local police and held for a short time on Saturday along with other protesters who tried to block a major highway into The Hague.

A Dutch environmental group is pushing for a stricter interpretation of the landmark 2021 court order for Shell Plc to slash its carbon emissions, seeking to turn the company’s appeal of that verdict to its advantage.

Shell told a Dutch court on Friday that a European climate ruling against the Swiss government supported their appeal against a 2021 Dutch climate ruling because it confirmed that states and not courts should set rules on emissions reductions.
