In 2015, a historic double success was achieved for sustainability and climate policy. The 2030 Agenda for Sustainable Development with its Sustainable Development Goals (SDGs) and the Paris Agreement on climate protection define an ambitious global target system. The group of the twenty most important industrialised and emerging countries (G20) should now resolutely press ahead with the implementation of both agreements and perceive the Great Transformation towards sustainability as a unique modernisation project that offers considerable economic development opportunities. For example, the complete decarbonisation of the global economy needed to avoid the greatest climate risks can only be implemented with a profound transformation of energy systems and other emissions-intensive infrastructures. The transformation inspires innovation and directs investments towards sustainability and climate protection, including in the sustainable infrastructures to be built and expanded. At the same time, the transformation can be used to fight inequality, i.e. to advance inclusion within societies as well as globally, and thus become a justice project.<\/p>\n
