The Sustainability Strategist is for you if…
You struggle to find sustainability experts who understand business

You feel overwhelmed by the complexity of integrating sustainability into your business
You need someone who simplifies the process, and lets you focus on what you do best while they handle the sustainability challenges.
Your sustainability needs keep evolving, requiring more than a single hire or conventional approach
The dynamics of sustainability demand flexible, scalable solutions that adjust as you grow.
You need a competitive edge in sustainability, fast
Speed is crucial to position you ahead of the competition swiftly and effectively.
You're experiencing fragmented sustainability services and piecemeal efforts that don't add up

ABOUT US
What is The Sustainability Strategist
The Sustainability Strategist is a transatlantic advisory firm helping investors and business leaders unlock business performance through pragmatic, strategy-led sustainability — at the asset level, across portfolios, and in positioning for what’s next.
Led by Thomas Baade-Mathiesen, our Chief Strategist — and backed by a curated network of elite advisors and delivery partners — we’ve delivered deep traction across business and the built environment.
Our work delivers agile corporate real estate results: from smarter approaches to green leasing and fit-out certifications (LEED, WELL, Fitwel) to portfolio-wide guidelines and strategic initiatives that leverage sustainability as a driver of enterprise value.
For private equity and active owners, we’re currently focused on portfolio company reviews — helping address the global bottleneck of unsold assets by surfacing hidden risks, unlocking upside, and strengthening exit readiness through sustainability-driven value enhancement.
Made in New York, we bring Big Apple drive to global projects — a sustainability speedboat that outmaneuvers the bigger ships.
