Despite clear scientific evidence that swift and ambitious climate action is necessary at the national level, many countries, particularly those with high emissions and GDP, are failing to implement policies to curb their climate impact.

Shared data and information are fundamental to mainstreaming climate action and promoting a coordinated and coherent response to climate change across government and society.

Long-term planning for climate and development requires tailored governance and institutional arrangements. Most countries have some experience with climate-change planning over near- and medium-term horizons through efforts such as nationally determined contributions (NDCs) and low-emissions development strategies (LEDS).
