Free Hong, Free Them All

Take action to call for Hoàng Thị Minh Hồng’s release and stand in solidarity with all climate defenders. 

Vietnam's bold climate ambitions were achieved through the unwavering efforts of climate defenders like Hồng. The alarming detentions of these brave individuals not only jeopardize climate action within Vietnam but also undermine the country's crucial role as a heavily climate-impacted nation and emerging economy.

We must call for a just and equitable response to climate change, one that empowers civil society to meaningfully participate in the development and monitoring of climate deals, without fear of persecution.

Stand with us as we strive for a better future, where climate justice prevails and all voices are heard.
