It’s time to rethink

Rethink /riːˈθɪŋk/ verb
To think again about a plan, idea, or system
in order to change or improve it.


ReThink is Hong Kong’s best attended and most ambitious business event for sustainable development.

The two-day expo and conference have been designed specifically for Hong Kong business leaders, sustainability practitioners and those responsible for researching and resourcing new sustainable strategies.

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 by 2050.

ReThink HK 2021 will be co-organised by the Business Environment Council – Hong Kong’s leading body for advocating sustainable strategies, environmental protection and contributing to the transition to a low carbon economy.

All delegate fees contribute to a beneficiary fund that supports dedicated impact projects with ReThink’s two incredible Hong Kong charity partners.


The challenge of protecting and restoring global ecosystems becomes more and more critical each and every day.

However, there is hope. And, there is ambition.

We want to hand future generations a realistic chance of sharing our planet in harmony with nature.

By changing the way we use resources, stabilising the environment and improving the lives of all through collective change and shared responsibility – we have an opportunity to show what humans are really capable of, but that opportunity is precious and must not be wasted.

The 2021 edition will expand on our founder’s ambition to curate a high-value business ecosystem event which delivers immediate and measurable impact, facilitates collaboration and that leads to real action towards a more equitable and climate-smart future for Hong Kong.

“Ultimately, purpose is the engine of long-term profitability.”

The 2021 edition will expand on our founder’s ambition to curate a high-value business ecosystem event which is outcome focussed, delivers immediate and measurable impact, facilitates collaboration and leads to real action towards a more equitable and climate-smart future for Hong Kong.

The content-led hybrid-format event model puts thought-leadership, insight and debate alongside innovation and real solutions.

2021 Event Themes

ReThinkTank

ReThink 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 2021 Advisory Committee members have advised on current and future trends, conference topics, potential speakers and cutting-edge technology/suppliers for the Innovation Showcase.

” Many individuals are doing what they can. But real success can only come if there is a change in our societies and in our economics and in our politics. “
