These targets have been a huge success. Now, the world must decide its targets for the next 15 years. The UN has proposed 169 targets, but not all are equally effective. Copenhagen Consensus has asked 60 teams of the world s top economists to weigh up the social, environmental and economic benefits and costs of 100+ targets across 22 global topics from Air Pollution and Education to Water. The world will spend $2.5 trillion on these targets 2016-2030. Picking the best targets can triple the benefits for the world s poorest. This book can help us choose better.
