Efficient Appliances for People & the Planet


Online Labeling Widget (draft version for beta testing)

CLASP worked with GTD to develop some code to facilitate the correct integration of the energy label and product information sheets onto the relevant webpages of their online store.

This tool allows retailers to easily display the energy label and product information sheet as required by the energy labelling regulations.

Purchasing appliances online, as well as doing research online prior to potentially going to a store, has become common practice in the EU. In the meantime, while attention to compliance has generally increased, online compliance has remained largely under-invested. Studies such as CLASP’s Evaluation of Online Energy Labelling Compliance in the EU have shown particularly low levels of online compliance, largely due to complex – and sometimes unclear – requirements. But how can compliance be facilitated for online retailers?

To help solve that issue, CLASP and GTD, in collaboration with the European Commission, have developed a tool in the form of a piece of code that can easily be integrated to any retailer’s website.

This Online Labelling Widget is designed to:

  1. Retrieve the required elements directly from EPREL
  2. Display them as required by the energy labelling regulation
  3. Be easily integrated in the front-end code of online stores
  4. Not require storage capacity on the side of the retailer

Our intention, following this beta-testing phase, is to deliver the widget to the European Commission to make it available from the EPREL portal, for voluntary use by online retailers. This tool is part of a broader effort and will be accompanied by harmonised guidance documents to the intention of both retailers and Market Surveillance Authorities.
