I haven’t switched to Belong yet so now I’m wondering how much carbon this review is creating. Although, I will say that this is excellent and everyone, like myself, should switch to carbon neutral internet. I really hope you do now so this carbon cost was worth it.

Awesome job Belong

This app is really interesting. I had no idea that using data contributes to carbon emissions. It was really revealing to see how much I personally contribute and definitely makes me think twice.
Well done to Belong for going carbon neutral.
