As of August 2021, monomoon is registered with Ecologi, a local environmental organisation who fund a number of climate positive projects around the world. This consists of a monthly subscription roughly commensurate with carbon offsetting. I will also be spending a proportion of sales on additional tree planting.
Whilst these types of schemes are only a part of the wider picture in avoiding on climate collapse, I encourage you to read through some of the information on their website and consider starting your own account with them, either personal or for your business. There may also be schemes local to you that are actively involved in rewilding, tree planting and developing and distributing carbon positive technologies that you might want to get involved with.
