The founder of ethical retailer, Inland Sea, is pledging to offset one gigaton of CO2 by 2030 – and he has the T-shirts to prove it. After Adam Costello learned of the benefits of seaweed as a mass absorber of CO2, he raised nearly £15,000 via crowdfunding to invest in seaweed farms, and launched a 100% biodegradable clothing range made from seaweed fibres.
