A large part of operating costs in urban water supply networks is usually due to energy use, mostly in the form of electricity consumption. There is growing pressure to reduce energy use to help save operational costs and reduce carbon emissions. This study shows how a hybrid linear and multi-objective optimization approach can be used to identify key energy consumption elements in a water supply system, and then evaluate the amount of investment needed to achieve significant operational gains at those points in the supply network.

Action on Plastic: On Track with the Regional Action Plan for the Arctic

Apr. 22, 2020

In October 2019, the Belfer Center's Arctic Initiative and the Wilson Center's Polar Institute co-hosted a workshop on Policy and Action on Plastic in the Arctic Ocean with the Icelandic Chairmanship of the Arctic Council. The Arctic Council asked Magnús Jóhannesson, the Council's designated Special Coordinator on Plastics Pollution and Marine Litter, and Gunn-Britt Retter, Head of Arctic and Environmental Unit at the Saami Council — who both participated in the workshop — to comment on some of the points that the report raises.
