Making sustainability for every business
Link your business to sustainability—powered by the founder’s 15 years of experience, with AI now being adopted to speed the data work.
About ThECO Link
ThECO Link—founded by Andy Tsang (15+ years in sustainability/ESG)—provides practical, affordable services for SMEs, from carbon management and TCFD to ESG reporting, EHS, and ISO systems. We are progressively adopting AI-assisted workflows to improve data quality and efficiency, helping us provide professional work at an accessible cost.
Mission and Vision
We are committed to make practical sustainability accessible to every business—especially budget-conscious SMEs in Hong Kong and the Greater Bay Area—by combining hands-on expertise with technology-assisted workflows.
Our vision is to be the reliable “Link” that helps HK & GBA enterprises align with international sustainability standards and turn ESG into credible, measurable performance.
“I started ThECO Link because sustainability should be usable and affordable for every company—not just the biggest. With technology, we cut complexity and raise quality. If we can be the small link that connects HK/GBA practice with international standards and turns intent into progress, we’ve done our job.”
