Sustainability consulting built by a hotelier

TG Consulting guides 25–250 room properties to GSTC certification and measurable carbon reductions.

Affordable and grounded in two decades of hospitality research-based practice.

Results that hold after we leave

38% waste cost reduction

GSTC Standards for Hospitality

Carbon emissions down 22%

Independent properties across Southeast Asia have achieved full GSTC certification with a small budget without in-house sustainability teams.

Energy audits and AI-assisted monitoring delivered verified scope 1 and 2 reductions at mid-sized properties with no capital overhaul.

A 120-room property in Penang cut disposal costs in year one through staff training and two targeted equipment changes.

What we do

Three ways we work with hotels

Certification consulting

AI monitoring and reporting

Staff training programmes

Continuous energy and emissions tracking using AI-assisted tools — so your carbon numbers are verified, audit-ready, and visible to your team in real time.

GSTC and other leading green standards — gap analysis, documentation, auditor liaison, and on-site staff preparation for properties at any starting point.

Practical training in waste management, energy habits, and sustainability reporting — built for the people who actually run the floor, not just the managers.

Your property. Your numbers.
