I have specialized in providing consulting services to companies and institutions who are dedicated to integrating sustainability, the UN's global goals, or ESG principles into their strategic framework for a sustainable transformation.

For authorities I offer expert editorial support in crafting impactful statements and reports in the realms of energy, climate, and sustainable development.

I deliver powerful lectures targeting company employees and individuals inundated with the dire realities of our world, but yet uncertain of taking actionable steps or their impact. Through engaging talks and insightful books, I offer a wealth of practical ideas to kickstart sustainable behaviour and drive positive change. It's not just for your own benefit, but for the legacy you leave for generations to come – your children, grandchildren, and beyond.
