This report summarises the outcomes from a two-day event on June 8 and 9 2016 that was organised by Feasta, Cultivate and Trócaire. It provided a briefing on CapGlobalCarbon - a campaign organised by members of Feasta's climate group - set it in the context of the commons, divestment and social justice, and generated ideas about how to implement it as part of a broader citizens' movement for a fair and sustainable transition from fossil fuels.
