01 / Make the call
Is this the right room?
Emitree's assessment of audience fit. Conference access does not establish buying intent or guarantee meetings.
Consider it if
You sell into APAC corporate sustainability, net-zero, ESG, or climate-tech budgets, especially where Hong Kong or Greater China multinationals set regional policy. The prior edition drew 9,500+ attendees, and sponsor logos from DHL, Cathay Pacific, Prudential, CLP, Zurich Insurance, and AWS put corporate buyers in the room alongside the NGO and consultant crowd.
Consider another event if
Your pipeline is US or EU compliance carbon markets, or you need a small curated room for high-touch enterprise selling. At 9,500-plus attendees across a broad climate and ESG remit, this is a high-volume expo-conference hybrid rather than a deal-making venue.
02 / Understand the audience
Who attends
The prior edition (6th, September 2025) drew 9,500+ attendees. Site copy describes the audience as business leaders, sustainability practitioners, and the people who research and resource net-zero and ESG strategy. The 2026 sponsor roster runs past 50 logos and includes DHL, Prudential, Zurich Insurance, CLP, Towngas, Cathay Pacific, AWS, ERM, ISS Corporate, HAECO, Jardine, Jardine Schindler, Marriott International, Siemens Mobility, New World Development, Swire Properties, Hongkong Land, Hang Lung, Kerry Properties, Nan Fung, InvestHK, and the Urban Renewal Authority. Seven pass types (Delegate, Expo-Only, Vendor, NGO, Student/Volunteer, Investor, Media) point to a mixed room of buyers, vendors, investors, and policy people rather than a single persona.
How large is the event?
The organizer reports over 9,500 attendees at the prior event (2025, 6th edition). The 2026 edition is the 7th, and site copy says it is expanding further, but no verified 2026 attendance figure exists yet since the event has not occurred.

The practical questions
Before you decide
Is ReThink HK 2026 still upcoming?
This edition ended on September 11, 2026. We have no later confirmed edition in this guide. Use the information as historical context.
Where can I find the ReThink HK exhibitor list?
We have not linked a public exhibitor directory for this edition. Ask the organizer about current directories and attendee access.
Does a company listing confirm who will attend?
A sponsor, exhibitor or speaker listing establishes that published role. It does not establish which employees will attend or whether they are buying. Previous-edition examples remain historical.
