As decision makers gathered at COP23 this November in Bonn, Germany, they considered strategies that could empower them to reach the United Nations Sustainable Development Goals (SDGs). Financing sustainable infrastructure is one of the keys to putting these goals in motion. According to Laura Canas da Costa, senior advisor in sustainable infrastructure financing at WWF Switzerland, developing nations will be building extensive amounts of infrastructure as they pursue the SDGs. Traditionally, up to 70 percent of infrastructure financing comes from the public sector.
