The HKGLS is an independent, not-for-profit and voluntary scheme for the certification of environmentally preferable products launched in December 2000 by Green Council (GC). The scheme sets environmental standards and awards "Green Label" to products that are qualified regarding their environment performance.

As with all eco-labelling programs, the aim is to encourage manufacturers to supply products with good environmental performance and provide a convenient means for consumers to recognise products that are more environmentally responsible, thus promoting a more sustainable pattern of consumption.

In establishing the standards, HKGLS draws from relevant international standards and is benchmarked with well-developed eco-labels to ensure credibility of the standards. An Advisory Committee, composed of members from the academia, industrial and commercial associations and environmental groups, oversees the policy and operation of the HKGLS.

As with the majority of eco labelling programs, HKGLS is an ISO (International Organization for Standardization) 14024(1) Type 1 label, which involves a third-party certification requiring considerations of life cycle impacts. Some of the key criteria contained in these standards also require compliance with applicable legislation.
