Vertical integration: GHG data alignment principles and practices for states and regions

This knowledge product is designed to support states and regions in understanding some of the practical and technical considerations for ‘vertical integration’ between national, subnational and local governments, with a particular focus on data for greenhouse gas (GHG) inventories and mitigation measures and targets.

It unpacks what is meant by ‘vertical integration’, the areas this is relevant to and the different forms this can take, from improving communication to alignment of processes to fully integrated systems. In addition, it outlines the benefits and opportunities of vertical integration for GHG data and sets out three principles which can help guide the selection of solutions to common challenges.
