For local governments, it is when expenditures are debated that it is possible to question them and to channel them towards the climate transition. That’s why I4CE and its partners co-constructed a common and shared methodology to assess a local budget according climate issues.  More information on this project is available at this link.   This document aims to present the assessment methodology step by step made by I4CE and its partners.      Hypothetical example representing results coming from the assessment  This methodological guide is made for staff and official elected that will be in charge of doing a climate assessment of the local budget. The guide is accompanied by a synthesis for elected officials and top management, by technical appendix on mitigation, a technical appendix on adaptation  of climate change. These documents are available for all local governments that want to launch a climate assessment of their budget.   In this guide, you’ll find:   1- Presentation of climate assessment of expenditures, its interestsand limits A- Introduction B- Climate assessment of budget in a few words C- Why to analyseits budget under climate criteria?
