This Guidebook illustrates how to create an efficient lighting NAMA based on a country-led national efficient lighting strategy. It aims to be a practical resource for governments (ministries of energy, environment, housing, climate change, finance, planning and others), private sector investors and civil society organizations. Users already may have developed an efficient lighting strategy, or may be in the process of developing one10. Furthermore, users may have an interest in articulating a NAMA for the implementation of the strategy, indicating how the country will turn strategy into practice. Articulating the NAMA facilitates communication with stakeholders, including citizens, the private sector, and national and international funders. Chapter 2 gives a generic background for the NAMA concept, origin and founding principles, as well as current interpretations among international stakeholders and the UNFCCC Secretariat. Chapter 3 provides specifics on how to develop a NAMA from a national efficient lighting strategy, using UNEP en.lighten initiative’s Achieving the Global Transition to Energy Efficient Lighting Toolkit and other tools, such as models and forecasts, to provide evidence for consideration by key stakeholders and potential funders. The UNFCCC has not yet promulgated strict requirements for NAMAs, but best practices from developed NAMAs, as well as donor and investor due diligence requirements provide a basis for evidence for present NAMAs. Chapter 4 introduces one of the most important elements of a NAMA: the measuring, reporting and verifying of the NAMA impacts, including emissions reductions and co-benefits. While basic requirements are given by the decisions of the Conference of the Parties, current practices in designing and implementing NAMAs show that accurate interpretation of measuring, reporting and verifying systems for NAMAs are crucial. Chapter 5 explains the current sources of financing for NAMAs, and ways that efficient lighting NAMAs could be financed. It introduces the ‘incremental costs’ approach as a means of quantifying budgets for ‘supported NAMAs’. Chapter 6 reviews and summarizes the information contained in this Guidebook, and offers brief advice on what steps to take in order to tap the potential of efficient lighting NAMAs.
