Cultured Meat A pragmatic solution to the problems posed by industrial animal farming Policy paper Industrial livestock production presents a growing problem on a global scale in terms of an- imal welfare, environmental sustainability, and human health. One solution might be cul- tured meat, in which animal tissue is grown in a controlled environment using cell culture technology, thereby making the raising and killing of animals for food unnecessary. This ap- proach shows great potential of meeting all the requirements of a humane, sustainable and healthy form of meat production. However, a great deal of scientific, technical, cultural and legislative challenges must be overcome before cultured meat can reach cost-competitiveness. Lack of funding is the main barrier to further development, and considerable upfront investment is needed for cultured meat to attain commercially viable retail prices. We therefore strongly support increased funding of cultured meat initiatives. This entails, in order of priority: research and development of technology suitable for mass production, promoting fact-based public discussion regarding the technology and its societal implica- tions, and eventual marketing of end products to consumers.
