Report on Measuring and Reporting Progress

The Milestone 5 Guidance: Measuring and Reporting Progress in Emissions Reduction, published by ICLEI in January 2013, introduced methods of conducting GHG emissions re-inventory and reductions measurement (i.e., to monitor and report progress of previous climate actions plan). This is the Milestone 5 in ICLEI’s Five Milestones for Climate Mitigation which was put forward before (see Figure 1). As pointed out, “it is important to develop systems and processes to monitor implementation, measure results over time, track changing conditions, leverage new information and ideas, and revise targets and plans as needed”, in order to “ensure that climate action plans are implemented effectively and on schedule” (ICLEI, 2013).

According to the Milestone 5 Guidance, there are two basic ways to track process of GHG emissions reduction: one is to show aggregate amount of emissions reduction compared to baseline inventory, and the other is to collect separate data from different individual projects under action plan and then to sum them up. ICLEI recommends the local governments to apply both methods when reviewing their climate actions plan, and provides detailed instructions of the measurements. Furthermore, in the section of Evaluating Emissions Reductions from Individual Projects, the methods are illustrated to specific categories: building energy, vehicle-related energy, community programs, and waste management. The Guidance also summarized the factors that need to be considered for calculating emissions, including project-related factors (see Table 5) and external factors, such as, population in the city, weather, economic growth, etc. Furthermore, Milestone 5 provides a framework on how to use above information to re-evaluate the existing Climate Action Plan and the emissions reduction goals.
