The Climate Technology Centre and Network (CTCN) worked closely with the Tongan Energy Department to develop the Tonga Energy Efficiency Master Plan (TEEMP) to help reduce electricity use and emissions from ground transportation – which together make up 55 percent of national emissions. The plan further complements the Tonga Energy Road Map which aims to reduce fossil fuel dependence through increased energy efficiency and improved supply chains, as well as reduce greenhouse gas (GHG) emissions and improve national energy security.
In order to assess the transformational impact of the TEEMP and the technical assistance provided, the CTNC applied ICAT’s Transformational Change Assessment Guide – a methodology to help policymakers and other users understand the relationship between policies and actions, and the expected or achieved transformational impact.
The ex-ante assessment, which took place from January to April 2019, sought to unveil the potential impact of the TEEMP up to the year 2030 and focused on three categories: GHG emission reduction, energy intensity and energy security.
With the use of a step-wise approach, a set of 20 proposed policies and actions were assessed within the electricity and transport sectors, including possible taxes and charges, subsidies and incentives, information instruments, infrastructure programmes, regulations and standards, and implementation of new technologies, processes, or practices.

While the ICAT Transformational Change Assessment Guide allows for analysis of more than one policy or action per assessment, the assessment of 20 policies and actions within two different sectors on a national level proved challenging in terms of aggregation of scores and weighting. For future assessments involving multiple policies and actions, it is recommended to apply it sector-wise.
