Gabriel Ho is a pioneering voice in the decarbonisation of aviation and heavy transport, sectors ranked among the world’s most challenging to abate. Drawing on more than two decades in the energy and chemicals industry—including engineering and leadership posts with ExxonMobil, Shell, Infineum, Ecolab, and BASF—Gabriel blends deep technical expertise with strategic foresight to translate sustainability ambitions into investable projects and policy action.

Today he fulfils twin entrepreneurial and advocacy roles. As Founder & Chief Sustainability Officer of the Asia Sustainable Aviation Fuel Association (ASAFA), he steers a multi‑stakeholder platform that convenes airlines, fuel producers, financiers, and regulators to accelerate sustainable aviation fuel (SAF) deployment across the region. In parallel, Gabriel is Founder & CEO of Energy Constructs, an advisory firm that has delivered some of Asia‑Pacific’s first-of-its-kind SAF and low‑carbon fuel feasibility studies.

Gabriel’s international presence is underscored by an intense speaking schedule: since October 2023 he has chaired, moderated, or spoken at more than 15 flagship conferences and executive seminars across Asia Pacific. Highlights include Argus Biofuels & Feedstocks Asia, Commodity Trading Week, the ISCC PLUS & SAF Conference, Boeing’s ASEAN SAF Seminar, Sustainable Aviation Futures APAC, and Future Energy Asia. At each forum, he translates fuel policy, techno-commercial assessments, and feedstock dynamics into actionable strategies—bridging financial models with real-world decarbonisation goals to help policymakers and industry leaders align with commercial realities.

Committed to talent development and public service, Gabriel mentors emerging professionals through the National University of Singapore, Singapore Polytechnic, and the Singapore Leaders Network Fellowship Programme, sharing pragmatic guidance on sustainability careers and systems thinking. He also serves as an Honorary Advisor to the UK‑based Global ESG Leadership Organization, contributing to strategic ESG case reviews that influence board‑room choices worldwide.

An alumnus of the National University of Singapore’s College of Design and Engineering, Gabriel embodies the school’s ethos of ethical engineering leadership. His career demonstrates how rigorous technical foundations, cross‑sector collaboration, and policy literacy can converge to unlock scalable climate solutions—offering an inspiring blueprint for engineers and innovators seeking to create lasting global impact.
