From Click-stream to Climate Gain
Why we chose
Half of Metrion’s infrastructure runs on Leafcloud’s “Truly Green” platform, where server racks act as mini-boilers, capturing waste heat to warm water for Dutch apartment complexes. Residents are literally showering with warmth generated by marketing data! This innovative design slashes up to 1,776 kg of CO₂ per kilowatt-year—equivalent to taking 1.4 cars off the road for every kilowatt of IT. “Marketing insights don’t have to cost the earth; they can contribute to the solution,” says Vincent Stoit, Metrion’s co-founder. Leafcloud’s CEO, Martijn van Zoeren, adds, “As cloud usage grows, we convert server waste heat into warm showers, creating a win-win where cloud infrastructure scales sustainably without the massive CO₂ footprint of traditional data centers.
70% by December 2025
Metrion currently processes 50% of its traffic on Leafcloud’s green infrastructure, but we’re aiming higher. By December 2025, our new managed database layer will push this to 70% green capacity. This step will amplify our ability to deliver GDPR-compliant, cookie-free server-side tracking while further reducing our environmental impact, supporting buildings with free hot water and cutting thousands of kilos of CO₂ emissions.
Impact at scale
With over €3.5 billion in transactions processed through Metrion’s technology, our partnership with Leafcloud has the potential to avoid tens of thousands of kilos of CO₂ emissions. For every 10,000 active Metrion stores, the switch to Leafcloud’s infrastructure saves approximately 17.8 tons of CO₂ annually—equivalent to removing 14 passenger cars from the streets.¹ These savings grow as we scale, proving that marketing tech can drive massive environmental benefits alongside business growth.
Better data, smaller footprint
Server-side tracking on Leafcloud’s climate-positive cloud means marketers see up to 30% more recorded conversions while emitting far less carbon. “Marketeers get more attributed conversions, buildings get free hot water, and the world sees less CO₂,” says Vincent Stoit.
