How Appliance Labelling Actually Moves Markets: From Malaysia's DSM Programme to Bhutan's S&L Scheme

Energy labels are one of the quietest success stories in energy policy. Every household in the OECD is now used to seeing an A-to-G scale on a fridge or an air-conditioner, and it changes the products manufacturers put on the shelf - not just what shoppers pick from it. In developing markets the same instrument, done well, can lock in a decade of demand-side savings without requiring anyone to change their behaviour. Done badly, it becomes a sticker no one reads. I have spent a lot of time on the difference.

Malaysia: DSM capacity building and the appliance rating scheme

Between 2002 and 2006 I served as Chief Technical Advisor and DSM Expert on the Danida-funded Capacity Building in the Energy Commission on EE/DSM programme in Malaysia. The scope covered project management, energy planning and DSM programming, database development and modelling - and the development and implementation of an energy rating and labelling scheme for appliances and equipment.

That label is now embedded in the Malaysian market. It was one of the first significant DSM instruments in the country and it fed directly into the National Energy Efficiency Master Plan for 2011-2020, which I later led (2010) as Chief Technical Advisor for the Ministry of Energy, Green Technology and Water - covering building energy efficiency, building codes, building energy rating and labelling, appliance labelling, cogeneration and related programmes. Earlier, in 2001-2002, I had also worked on the Malaysia Industrial Energy Efficiency Improvement Project (UNDP/GEF) on rating schemes and policy for industrial equipment - specifically thermal boilers and electrical motors.

Bhutan: designing an S&L programme for the 15 most energy-consuming appliances

In 2018 I served as Energy Efficiency Specialist for the Asian Development Bank's Promoting Clean Energy Development in Bhutan project. The task was the development and design of a Standards and Labelling (S&L) programme for Bhutan's 15 most energy-consuming appliances, including harmonisation of standards with the country's main countries of import, and development of Minimum Energy Performance Standards (MEPS), High Energy Performance Standards (HEPS) and energy-rating labels - covering air-conditioners, heat pumps, chillers and water heaters, among others.

Bhutan is a specific case: nearly all appliances are imported, primarily from India, and the domestic testing infrastructure is limited. That shaped the design in three important ways.

• Standards had to be harmonised with the country of import so that Bhutan did not create a market of one - this is what makes the scheme workable at the border.
• Testing and enforcement had to rely, in the near term, on recognised third-party testing and manufacturer declarations, with a phased build-out of domestic verification capacity.
• The product scope had to focus on the 15 most energy-consuming appliances - not everything at once. Get those right and the label starts to shape the whole market.

What makes an S&L programme actually work

• Test procedures the manufacturers already use, not bespoke national methods
• MEPS levels calibrated to the market so they cut the tail without killing supply - and updated on a defined revision cycle
• Labels that answer the question the shopper is actually asking (energy cost per year matters more than kWh in the abstract)
• Market surveillance you can afford to run - even a modest random-sampling programme deters non-compliance
• A clear alignment with trading partners' schemes; nobody wins from a bespoke national label with no supply chain

How this ties into today's decarbonisation agenda

Room air-conditioners are one of the fastest-growing loads in Southeast Asia and South Asia. Every year of delay on MEPS locks in another cohort of inefficient units running for 10-15 years. That is why appliance labelling and MEPS remain in almost every credible national energy-efficiency action plan - including the ones I have worked on more recently for Türkiye and in the World Bank's building-sector operations. It is unglamorous policy work with disproportionate impact.

If you want to move a national efficiency curve, start with the appliances people are about to buy anyway - and make sure the label on the shelf tells them the truth.
