Since then, Green Fuels has won numerous awards and in 2013 was granted a Royal Warrant by HRH the Prince of Wales for its ongoing supply of sustainable biofuel to the Royal Family, for which James is the Royal Warrant holder. Today, the company has supplied bio-refineries on every continent (bar Antarctica). In 2015, James won Entrepreneur of the Year at the New Energy & Cleantech Awards in recognition for these achievements.
