HONG KONG – 7 September 2026 - The seventh edition of ReThink HK, Hong Kong's flagship climate action and sustainable business event, will open on 10–11 September at Hall 1, HKCEC. Restructured around five dedicated Thematic Zones — Cities, Energy, Impact, Innovation, and Resources — the event is expected to convene 10,000+ attendees, 500+ speakers, and 350+ solution providers as Asia's business sector shifts from climate target-setting to operational delivery. The restructured format is designed to help business leaders convert ESG strategies into operational results amid intensifying regulatory pressure globally.
Since 2020, attendance has grown more than 12-fold - a 1,150% increase in six years. Nearly one-third of attendees hold board-level or sustainability leadership roles, reflecting the event's position as a decision-maker forum for the region's net-zero transition.
Streamlining Climate Action: The 5 Thematic Zones
“As companies transition from setting climate targets to executing operational roadmaps, the demand for practical, scalable solutions has never been higher,” said Mr. Chris Brown, Founder & CEO of ReThink HK. “We have restructured the entire conference around five thematic zones to help business leaders forge meaningful partnerships and convert ESG strategies into measurable business value.”
The five Thematic Zones are structured as dedicated solution centres. The following showcases the highlights of each zone, while the full programme spans a broader spectrum of cross-cutting technologies, partnerships and innovations.
The Cities Zone targets actionable solutions in sustainable infrastructure, green building technologies and liveable urban engineering for Asia's densely populated cities.
The Energy Zone explores the region's evolving energy ecosystem, from renewable integration and grid decarbonisation to sustainable aviation fuel, clean maritime fuels and the electrification of transport.
The Impact Zone convenes strategic ESG governance, green finance for SMEs, social value creation and community-level climate action.
The Innovation Zone features cutting-edge climate technology, AI-driven sustainability tools and the university spinout and startup ecosystems commercialising research into deployable solutions.
The Resources Zone presents circular economy solutions, waste reduction innovation and sustainable materials management across Asia's manufacturing and supply chain networks.
