Ethiko is a service of computer and telecommunications engineering specialized in the conception of web designs with a low ecological footprint. By tackling their energy consumption, their CO2 emissions and their water consumption, we have therefore developed a unique digital web eco-design process based on the standards of the Green IT collective. Our development teams provide our clients with this approach throughout their web projects. Finally, we measure the reductions obtained in a concrete way thanks to a tool intended for the popularization of eco-design, made available to all: https://ecodesign.dev/
