Two years on from what was a very optimistic COP 21 in Paris, the general sense of where we are now is less certain. While there is a lot still to be positive about – especially some renewable energy generating technologies becoming much cheaper, there is a different landscape with new geo-political challenges, not least the changing political Administration in the US. With these uncertainties as a backdrop to climate change in 2017, Elsevier has brought together 3 leading experts to help understand the challenges related to implementation of SDG 13 and where we should go from here. The speakers include Alice Larkin from the Tyndall Centre for Climate Change, Roland Roesch from IRENA and Jenny Heeter from NREL. These speakers provide some contemporary context around the themes that we should be aware of, including progress on the latest Carbon reduction targets; importance of innovation within renewable energy sector; and how policy has a vital role to play.
