In 2015, several reports were published by Chatham House, including "Nigeria’s Booming Borders: The Drivers and Consequences of Unrecorded Trade", which urges formalizing trade and driving more sustainable and less volatile growth; "Changing Climate, Changing Diets: Pathways to Lower Meat Consumption" examines a reduction in global meat consumption as critical to keeping global warming below the "danger level" of two degrees Celsius; "Heat, Light and Power for Refugees: Saving Lives, Reducing Costs" examines the reasons why energy provision to displaced people undermines the fundamental humanitarian aims of assistance; and "Towards a New Global Business Model for Antibiotics: Delinking Revenues from Sales" argued for revenues for pharmaceutical companies to be de-linked from sales of antibiotics to avoid their over-use and avert a public health crisis.
