About hwernu

hwernu provides environmental impact assessment tools for the digital world. Our Web Page Carbon Footprint Estimator helps website owners and developers understand the CO2 emissions associated with their web pages based on data transfer size, server energy sources, and user device types.

Founded in 2023 by sustainability technologists, our mission is to raise awareness about the environmental impact of digital services and provide actionable insights to reduce online carbon footprints. Our tools use industry-standard methodologies but should be considered estimates rather than precise measurements.
