Twenty years in sustainability, most of them building Edge Impact from a small consultancy into a global purpose-led firm of 100+ people.
Now focused on advisory board roles, technical advisory, and early-stage tech.
Whether you need sustainability credibility at board level, technical depth for a critical assessment, or a growth partner who has been through the inflection points you're facing.
Sustainability governance, climate risk oversight, and the credibility to challenge assumptions at board level.
Technical depth across carbon strategy, sustainability measurement, and product transparency. Senior credibility when rigour matters.
Scaling climate tech ventures. Governance maturity, pressure-testing claims, and candid perspective at inflection points.
Substance with levity. Keynotes, panels, and executive workshops on sustainability governance and scaling purpose-driven companies.
Recommendations from colleagues, clients, and collaborators.
"Jonas's vision and passion for a more sustainable world, his deep expertise in technical sustainability, as well as his character and integrity, are exemplary and of the absolute highest order."
"Jonas is one of the smartest people I've had the pleasure to work with. Quietly brilliant, he has consistently blended deep thinking, practical know how and a can do spirit to make an impact on our planet."
"I worked with Jonas for nearly 8 years, and can honestly say he's the definition of authentic leadership. He's someone that is trustworthy and trusting, providing his team with the vision he wants to realise and allowing others to find their own way of making those things happen."
"One of the god fathers of sustainability. Making sure that the circular bio-economy and the sustainable world we need happens. Having watched him over the last 10 years I'm glad we are in his hands."
Operating principles distilled from co-founding and scaling Edge Impact. Less a consulting framework than a note to myself for the next time I'm about to make a decision I've made badly before.
Open to non-executive director roles, advisory board positions, technical advisory, and speaking.
