Demand-Side Efficient Lighting

Demand-Side Efficient Lighting is a reduction method run by Clean Development Mechanism. People often refer to it by its code, AMS-II.J. It works in the energy efficiency space.

In short

Efficient lighting technologies replacing inefficient lamps.

What it is

This small-scale Clean Development Mechanism methodology covers demand-side projects that distribute and install energy efficient lighting, such as compact fluorescent lamps and other efficient lamps, to replace less efficient baseline lamps like incandescent bulbs. Eligible activities reduce electricity consumption for lighting in residential and similar applications while providing comparable light output. Emission reductions come from the lower grid electricity use and the associated avoided emissions. Each Certified Emission Reduction represents one tonne of carbon dioxide equivalent.

What it rewards

The reward is a credit called a Verified Carbon Unit (VCU). One credit stands for one tonne of carbon dioxide kept out of the atmosphere (or taken back out of it). One tonne of CO₂-equivalent verified-and-issued. A whole period of work is issued as one batch of credits at a time, in the same way a registry issues a batch.

What gets measured

To earn VCU credits, a project has to measure and prove a few things. An independent reviewer checks the evidence before any credits are issued.

  • The baseline: what would most likely have happened to the land or the emissions if the project had not gone ahead.

  • The activity data for the period, with clear units and a clear source for every number.

  • The net result actually achieved, checked by an independent reviewer before any credits are issued.

Who takes part

  • Standard Registry. Owns the policy, approves participants, anchors each issuance to its evidence.

  • Project Proponent. Registers the project and submits monitoring reports.

  • Validation & Verification Body. Independently validates the design and verifies monitored data.

How it works

  1. 1

    The project team registers the project and its plan.

  2. 2

    An independent reviewer checks that the plan is sound and that the benefit is real and would not have happened anyway.

  3. 3

    The team looks after the site and measures the agreed indicators over time.

  4. 4

    The independent reviewer verifies those measurements.

  5. 5

    Credits are issued for the verified result, and a buyer can retire a credit to claim the benefit once.
