 For the SEI's part and to continue to try to be a relevant knowledge partner, it would be great if the SEG summit could shed light on what are the bottlenecks, what are the key impediments that are facing national governments and how can we contribute knowledge. For example, is it more evidence on the costs and benefits of taking action, the economics of sustainable development, or is it how we overcome difficult goal conflicts? We tend to highlight a lot of synergies, but there are also goal conflicts, so how can we support governments, deal with those in a systematic, science-based and responsible way.
