Can the sustainable development goals be made smarter?

UN Secretary-General Antnio Guterres has asked the world body to extend the Sustainable Development Goals (SDGs) to 2050 as part of its annual summit, the UN Summit of the Future. The SDGs were adopted by the world body in 2005 and aim to halve global warming by 2050. Guterres called for an “ambitious” agenda to achieve the goals.
