This guidance note focuses on the development and maintenance of market baselines and market monitoring activities as tools to inform minimum energy performance standards (MEPS), labelling, and supporting policies for energy efficient lighting. It is primarily aimed at policymakers that wish to establish, or update, policies to facilitate the transition to efficient lighting and provides a practical resource for those developing a market baseline for the first time, or those who are looking to update existing baselines for market monitoring purposes.

A market baseline provides a detailed snapshot of the products available in a market at a given point in time, and provides a sound technical foundation for the development of new, or revised, policies for efficient lighting. Market baselines enable policymakers to gain a thorough understanding of product availability, performance, pricing, and other important factors that influence policy development. As market baselines are refreshed over time, they enable policymakers to identify, and understand, market trends and responses to government policies and programmes, and this in turn supports the development of more effective MEPS and supporting policies in the future. 

Market baselines and market monitoring are typically the responsibility of government agencies that have the legal mandate to establish MEPS and other product regulations or energy efficiency programmes for an economy, such as mandatory and voluntary labelling programmes. Governments may also establish a series of energy efficiency levels. For example, to include high efficiency performance standards (HEPS) to recognise high-performance products in addition to MEPS to eliminate low-performing products. 

Best practice suggests that policymakers should allocate adequate financial and human resources to data collection and analysis efforts, and support these efforts with robust planning in order to ensure high quality outcomes. 

In terms of resources, market baselines are typically funded directly by a government and/or donor agencies, and staffed with a combination of government and contractor personnel. Third-party stakeholders, including industry associations, manufacturers and research institutions, often support the process by supplying data and assisting with its analysis.
