A key mechanism for financing CDR, particularly via nature-based solutions is the Carbon Market, primarily those for voluntary action by companies and individuals. However, whilst these are growing rapidly, they are not built for the scale needed. They increasingly utilise robust project design and impact measurement techniques but are reliant upon outdated technology and the assets produced - carbon credits - are traded on disparate marketplaces, most of which are difficult to access, opaque and low tech. The market is thus reliant on expensive brokers and retailers, who in many cases add margins upwards of 30% and benefit from the marketโs complexity and opaque prices, making it expensive and inefficient to both buyers and sellers.
