We are Spark Sustainability

Spark Sustainability leverages emission data to improve customer loyalty and employee engagement for our partners. We consult businesses in emission calculations and offer digital tools that highlight the climate benefits of low-carbon products.

Via the Carbon Donut app, we enable and inspire people to make climate-friendly choices in everyday life. We give you science-based facts on greenhouse gas emissions, and show you the huge impact our actions have when we combine our efforts. But most of all, we show you that taking climate action isn’t about giving up on things. It’s about improving quality of life.

We spark climate action

We envision a world in which personal climate action drives business decisions, political agreements and technological advancement to stop climate change. As a first step to get there, we will enable 1 billion climate actions by 2025. This will result in a reduction of more than 100 billion kg of CO2, or roughly twice the annual emissions of Finland.
