ReThink HK

A Passionate & Dedicated Team

EnviroEvents (ReThink) Limited

We are a team of passionate Hong Kong residents whose goal is to drive sustainable development in our amazing city.

ReThink HK is a unique annual event that helps organisations align sustainable business practices at every stage of their value chain, showcases innovation and the solutions that accelerate sustainable transformation. ReThink HK unites the ecosystem so all stakeholders and communities can contribute to and look forward to a climate-smart and equitable city, for everyone.

The annual ecosystem event operates under license from the business and sustainability communities that it is privileged to support – uniting stakeholders, demonstrating the business case and strategies for change against a backdrop of innovation and the sustainable solutions needed to achieve a circular economy and strive for a carbon-neutral Hong Kong before 2050.


ReThink HK is supported by a group of cross-sector sustainability leaders who form the advisory panel and provide key insight into how ReThink can best address the needs of the Hong Kong ecosystem.

Meeting as a group and individually, the ReThink HK Advisory Committee members advise on current and future trends, conference topics, potential speakers and cutting-edge technology/suppliers for the Showcase Expo.
