Make My Money Matter is a UK campaigning website (Make My Money Matter) that explains how the £3 trillion in UK pensions and major high-street banks’ financing of fossil fuels and deforestation drives the climate crisis and urges practical individual and institutional actions—green your pension (move to sustainable funds and ask employers to adopt greener defaults), switch to greener banks, and push to stop pension and bank financing of new fossil fuels while unlocking investment for climate solutions. Cited in Part 3, Chapter “Our Financial Vehicles In Action” (p.123), the site provides a contemporary, action-oriented example of how reallocating pensions and banking capital can shift financial flows toward a just, low‑carbon transition.
