The Open Philanthropy Project recommended a grant of $1,500,000 over three years to Compassion in World Farming USA (CIWF USA) for general support. CIWF USA has been one of the major contributors to the success of corporate reforms for layer hens, and intends to use these funds to seek implementation of existing cage-free reforms and to secure new corporate broiler welfare reforms. Open Philanthropy wrote more about its decision to support CIWF USA in the writeup for Open Philanthropy's first grant to them, made in April 2016.
This grant falls within Open Philanthropy's work on farm animal welfare.
