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).

For the past two years, at the invitation of the Argentine and Japanese G20 presidencies, UNDP and WRI have together advised the G20 Climate and Sustainability Working Group on the key role that long-term strategies and NDCs are playing to advance the G20 agenda and address climate change.

This paper discusses the development of the accounting guidance under the Paris Agreement.

The Paris Agreement is a hugely significant step towards reaching a zero-carbon and resilient world. But challenges remain if we are to limit temperature rise and increase capacity to adapt to climate impacts.
