We believe that the climate impact of the ICT sector can and must be reduced. Not by using the internet less, but by using it smarter.

Our mission is to help making the digital transformation into a green transformation by focusing solely on web technology that emits as little CO2 as possible.


We believe that the utilization of green web technology is an important step in reducing the carbon footprint of the ICT sector. This is how we're actively working towards the UN's 13th World Goal, which is about combating climate change.

Our vision is to make sustainable web technology accessible to as many people as possible.
