Ethex is included because it is a UK platform that enables everyday investors to deploy capital into impact-focused vehicles—notably community shares, renewable-energy bonds and an IFISA—providing live examples (e.g., community energy and Big Solar Co-op offers), impact figures and due-diligence/risk information; this makes it a practical, directly relevant resource for Part 3’s chapter “Our Financial Vehicles in Action,” which tours how the Mills’ investments put money to work for social and environmental change.
