19 Oct 2021 As countries recover from COVID-19 pandemic, there are growing calls across societies to build forward better, more inclusively and greener, and accelerate the transition to net zero-carbon economies. This Guidance Note draws on the experiences in climate budgeting that emerge from Asia-Pacific countries and captures emerging global trends with adopted principles and steps involved. It builds on the work of UNDP as a technical partner in the Coalition of Finance Ministers for Climate Action. It aims to provide the necessary information with a systematic approach to policy makers and practitioners for integrating climate change into budgets and strengthening climate policy planning and budgeting, with a focus on Medium-Term Budgeting. The Guidance Note: Provides a step-by-step approach to integrating climate change into the budget preparation and approval stage, in line with public finance management (PFM) principles. Suggests possible interventions at each sub-stage for different sets of stakeholders. Provides supplementary information on relevant tools and case studies of various countries. Outlines principles that are responsive to the gradual strengthening of PFM reforms across the different stages of the budget cycle.
