Decades of dependence on a carbon-based economy has produced grave injustices on a global scale. Our children, grandchildren and the many vulnerable communities and species on the planet now have to carry the burden of a crisis that they have not caused. The youth are forced to act like grown-ups. Faced with government inaction despite the stark warnings from scientists to act, young people chose to leave school to confront a system that failed us all, but particularly those with the least power. Years of empty promises to address the climate emergency have created intergenerational mistrust. Our children and grandchildren don’t trust us as adults, citizens, business people and politicians. Around the world, young people are taking to the streets to reclaim a safe future. They are not alone in this fight. They have inspired us to join them in saying: no, our future is not for sale and governments must ensure that fossil fuels are kept in the ground. We will exert all efforts to guarantee their victory. This newly generated grassroots power is putting the last nail in the coffin of the fossil fuel industry and advocating for true, rights- and evidence-based solutions to climate change. It is essential that governments act on climate and work with vulnerable communities to protect them from dangerous warming while we ensure ecosystems can thrive and restore. The science is clear we must move faster to avoid catastrophe by decarbonizing the economy, cutting emissions by half by 2030 to reach zero emissions by 2050. We, the members of civil society, stand in solidarity with students worldwide demanding climate justice. We shall relentlessly support their effort until they meet the success of their struggle through concrete government action to resolve the climate emergency.
