Fossil fuel supply needs to be phased out as well as demand, and should be accomplished in a predictable manner, to ensure a just transition. When the Lofoten Declaration was launched in September 2017, an indefinite moratorium on oil and gas production already existed in Costa Rica, and oil and gas moratoriums applied to several biodiversity hotspots; more policies to restrict fossil fuel supply have been recorded since the Declaration’s launch. Such a transition can not happen overnight and requires a just transition for workers, communities and entire countries.
