In 2019, thousands of Danish children and youths took to the streets. They stayed away from school to demonstrate for the climate, mobilise their parents and grandparents, and demand action – now! When elections were called later the same year, it was clear that green climate policies attracted voters, and suddenly the climate was at the top of the political agenda. ‘70⁄30’ portrays the creation of one of the world’s most ambitious climate laws, with the goal of reducing Denmark’s CO2 emissions by 70% by 2030. But will the politicians, citizens and industry be able to come together to make Denmark a green pioneer? Or will the election promises and green ambitions crumble when the new climate law is faced with reality?
