Forum for the Future has produced a great report for Aviva Investors called sustainable economy in 2040: a roadmap for capital markets (pdf).
In focusing on a key leverage point -- capital markets -- and taking a backcasting approach, the report gets around the usual stalemate of investors seeing the way things are and investing accordingly, while many in civil society cry foul as those investments accelerate our progress down an unsustainable path; and provides actionable steps for the investment community to take in creating a sustainable society.
It provides the rationale for why and strategies for how investors can be more proactive in creating the kind of economy we need in the long-run, with a focus on 5 key areas: energy, health & wellbeing, mobility, food, and finance.
The report also serves as a call to action ahead of the Rio +20 summit in June 2012.
A great resource, and worth the read.
