        We are looking for a lead developer to head the development of our app, The Donut, a carbon emission tracker that makes climate action easy.

        About Spark Sustainability & our mission

        70% of global greenhouse gas emissions stem from consumer choices, which means we are all part of the solution to stopping climate change. At Spark Sustainability, we make climate action easy. We connect climate-conscious individuals with companies that provide sustainable solutions to accelerate the shift towards a carbon neutral society. 

         Our mission is to 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.
