- International Council on Mining and Metals, “Planning for Integrated Mine Closure: Toolkit” (London, UK: 2008). The International Council on Mining and Metals is an organization dedicated to improving the sustainability of the mining and metals industry. They use collaborative measures to address sustainable development. This toolkit offers tools and guidance for planning for project closure in collaboration with communities from the initial stages of a project. It was developed for the mining industry, but the tools are useful guides and could be adapted to the oil and gas sector.
