Priorities:

In May 2008, Lomborg convened the second Copenhagen Consensus Center conference. This time eight leading economists, including five Nobelists, considered how to allocate a theoretical $75 billion during the next four years to solve 10 of the world's largest problems... The panel's top four solutions: providing vitamin A and zinc supplements to poor children, liberalizing trade, fortifying salt and staple foods with the micronutrients iodine and iron, and expanding childhood immunization. Cutting greenhouse gases came in at the bottom, although another approach to global warming—R&D spending on low-carbon energy technologies—was a mid-list priority.
