HONG KONG…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 HK is Hong Kong’s best attended and most ambitious business event for sustainable development.

The two-day conference and expo, which will host 6,000+ attendees in September 2023, have been designed specifically for Hong Kong business leaders, sustainability practitioners, and those responsible for researching and resourcing new sustainable strategies.

Our Purpose

The challenges of reducing GHG emissions and securing global net-zero emissions in order to protect, and then restore, the balance of global ecosystems become more and more critical each and every day.

It is only through cross-sector, private and public collaboration that the scale of change needed can be achieved – ReThink HK exists to accelerate that change in Hong Kong.

We want to hand future generations a realistic chance of thriving in a city that is in harmony with nature, uses resources efficiently and contributes towards a low-carbon and circular economy.

By changing the way we consume, invest and operate our businesses we can reduce our impact on the environment and improve the lives of all through collective change and shared responsibility – we have to act now and accelerate the rate of change. We can help demonstrate what Hong Kong is really capable of, but the opportunity is precious and must not be wasted.

Every company and every industry will be transformed by the transition to a net zero world. The question is, will you lead, or will you be led?

Larry Fink, Chairman and CEO, BlackRock, January 2022

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.

The Conference

The past three editions have each expanded on our founder’s ambition to curate a high-value business ecosystem event that 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.

Following a hugely successful 3rd edition, in October 2022, the ReThink HK conference is further expanding and continues to be curated in partnership with leading business associations, industry bodies, NGOs and campaign groups.

As a content-led conference-expo hybrid, ReThink HK puts thought-leadership, insight, and debate alongside innovation and real solutions.
