Countries hit hard by recent climatic events, from category 5 hurricanes in the Caribbean, to severe flooding in South Asia, are demanding swift action. Not just in terms of disaster recovery, but also with regard to adaptation and mitigation policies that can reduce and address the effects of climate change. One recommendation to come out of the climate change workshop at the 63rd Commonwealth Parliamentary Conference (CPC) in Dhaka this month was that ‘legal reform can make a low carbon and climate resilient development pathway possible by reinforcing policy, strengthening institutions and mobilising resources towards climate change activities’. There is high demand for a tool that can support countries in realising the nationally-driven focus of the Paris Agreement, by providing collective experience in the strengthening of national laws related to climate change.The Paris Agreement’s goal is to hold the increase in global average temperature to well below 2°C, to pursue efforts to limit the increase to 1.5°C, and to achieve net zero emissions in the second half of this century. Realising such a goal will require widespread socio-economic changes in diverse societies around the world. In addition to the challenges of decarbonisation, countries face climate change consequences across themes as diverse as urban planning, potable water, sanitation, agriculture, and loss of territory due to sea-level rise.
