Sustainability Transformability - Resilience by Circularity

Live up to your strategy

For more than 15 years, I have been helping organisations implement sustainable solutions. Speaker and founder of the Sustainability Circle.

How I work

Large sustainability transformations need strategic choices, technical depth and collaborative momentum.

As a partner at Implement Consulting Group, I focus on large transformations with a collaborative approach — helping leadership teams translate sustainability ambition into concrete choices across strategy, products, production and governance.

I combine scientific methods, commercial thinking and organisational implementation to make sustainability actionable, measurable and relevant for growth.
