for a responsible, fair & sustainable food system

About GM Freeze

GM Freeze is the UK’s umbrella campaign on GM food, crops and patents.

Formed in 1999 as the Five Year Freeze, we became a not-for-profit registered company in 2005. Our members include large national charities, small specialist organisations, scientists, farmers, retailers and grassroots campaigners.

GM Freeze is run by a small staff team and a Management Committee  elected each year at the Annual General Meeting.

What we do

GM Freeze is working to help create a world in which our food is produced responsibly, fairly and sustainably.

We consider and raise the profile of concerns about the impact of genetic modification. We inform, inspire, represent and support those who share our concerns. We campaign for a moratorium on GM food and farming in the UK. We oppose the patenting of genetic resources.
