About

Spent the last decade designing and retrofitting stormwater systems for coastal cities. Here because the next decade of climate adaptation is going to be community-led, and I want to put my plans where my mouth is.

#00046Urban Carbon Neutrality

Cities worldwide are committing to carbon neutrality, but the gap between political targets and physical reality is vast. Decarbonizing urban heating, transport, construction, and waste systems within a generation requires coordinated action across sectors that have never worked together at this speed.

#00039Forest Dieback Crisis

Forests across Europe and beyond are experiencing accelerating decline driven by climate change. Drought, rising temperatures, insect epidemics, and fungal diseases are killing trees at unprecedented rates across multiple species, turning forests from carbon sinks into carbon emitters.

#00054Car Deregistration Incentive with Mobility Credits

Offer residents a financial incentive to permanently deregister a car, paid as credits redeemable for public transit passes, bike-sharing, car-sharing, and cargo bike rentals rather than cash. This ensures the incentive shifts behavior rather than just subsidizing a transaction. Basel's Umweltprämie (CHF 1,500, launched September 2025, 400 slots) is a working pilot of this approach. Helsinki's mobility-as-a-service platform demonstrates the broader ecosystem needed to make car-free living genuinely convenient.

#00066Municipal Climate Platform for SME Coordination

Create a public-private platform that provides SMEs with simplified carbon footprint assessment tools, pre-negotiated group rates for retrofits and fleet electrification, peer learning networks organized by sector, and a single point of contact for navigating subsidies and regulations. The platform aggregates demand across hundreds of small businesses to achieve economies of scale that no single SME could access alone. Basel's Klimaplattform der Wirtschaft, with 800+ member companies and quarterly business lunches since 2014, is a working model of this approach.
