About LOOP

LOOP stands for Low-carbon Office Operation Programme. The programme has been established to enable Hong Kong companies and organisations to become part of the solution to climate change. Please click here to download the LOOP factsheet.

By participating in LOOP, companies or organisations are engaged with a group of like-minded forward-looking leaders to reduce their greenhouse gas emissions generated from office operation via the adoption of managerial and technological best practices, staff behavioural adaptation, and a labelling scheme.

LOOP companies or organisations can access a tool-kit that allows the measurement and analysis of the carbon performance of an office, formulation of emissions reduction strategy, and reporting on their improved carbon performance.  To learn more about LOOP online application tool, please click here.
