Governments reached an important agreement in Paris in 2015 for tackling the growing challenge of climate change, which former Secretary General of the UN, Mr. Ban Ki-moon described as the “defining challenge of our time”.  In 2015, the UN General Assembly also adopted 17 Sustainable Development Goals (SDGs), which in an integrated manner provides a framework for a just and humane society devoid of future risks for human beings and other species.  More recently, the Intergovernmental Panel on Climate Change (IPCC) has brought out a special report on the target of 1.5°C to be met by the end of the century.
