Does What Gets Measured Get Done? An Evaluation of the Impact of the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories on City Climate Action
Children's Investment Fund Foundation
- Most cities that ever participated in TA complied with the program’s immediate objectives of generating GHG inventories, and most inventories are based on the GPC framework.
- High turnover and resulting differences in the intensity of program participation affected ever-participating cites’ capacity to achieve full compliance of program objectives.
- Relative to a group of comparison cities, cities selected for C40’s TA program performed better in the reporting of GHG inventories and CAPs when comparing performance in 2016–2019 following the start of TA (“post”) to performance in 2011–2015 prior to the start of TA (“pre”).
- Relative to comparison cities, we find that TA had small, positive effects on the reporting of mitigation actions (7 percentage points).
This report is Mathematica’s final evaluation of the CIFF-funded C40-implemented technical assistance (TA) program to help Global South cities build their capacity to collect, report, and act on emissions inventory data. We use a matched comparison group design to construct a counterfactual of the extent of climate data and climate policy action that cities receiving TA would have been likely to pursue in the absence of the TA program. We find that most cities that ever participated in TA complied with the program’s immediate objectives of generating GHG inventories, and most inventories are based on the GPC framework. Cities that actually received TA reported consistently larger effects than cities invited to participate in the program.
