Among the questions this Tomorrow's Company report asks is if companies are prepared for the scale of the energy revolution in prospect whether the system should be updated to take more account of emerging risks of runaway climate change as well as the widely accepted evidence of global warming - and if so, whether business should be proactive in driving reform? It also looks at what policy frameworks business should work with government to prioritise, so that business can play its full role in building tomorrow's green and clean economy and what the transition to the low-carbon world might cost.
