Bates Dairy, Southport, Merseyside
Bates was founded in 1939 by Edward and Elsie Bates and has been family for three generations. They're fully committed to reducing carbon emissions, investing in solar power and entering a climate change agreement with the environment agency. All their milk comes from within a 20-mile radius, and they reuse their glass bottles up to 50 times. If it ain't broke, don't fix it.
