About Testa & Tegmen

A consultancy of environmentalists, policy advisors and industry practitioners.

We are united by a common goal: creating a sustainable ecosystem where businesses and the environment thrive in harmony — and where the next generation of environmental professionals is equipped to lead.

Our Mission

To make environmental regulation, sustainability strategy and capability building work — together, and in service of long-term value.

Testa & Tegmen was founded on a single conviction: regulation done well is a strategy unlock, not a tax. We work alongside leadership teams, sustainability officers and policy desks across India to translate complexity into action.

Beyond consulting, we run a Learning Academy for students and early-career professionals — because the climate transition needs a workforce equal to its ambition.
