The world faces unprecedented risks and the threat of irreversible damages due to soaring levels of greenhouse gas (GHG) emissions. As a nation, Indonesia has the potential to champion the global climate efforts. With huge renewable potential exceeding 440 GW and substantial reserves of critical mineral for decarbonization including nickel, tin, and copper the country is positioned to foster the development of sustainable industries. Against this background, the Indonesia Sustainability Forum (ISF) is established as a platform to foster collaborations and best practice sharing across stakeholders in decarbonization actions, ultimately advancing the global concerted effort in pursuing a sustainable growth.
