Californians Against Waste is a non-profit environmental research and advocacy organization based in Sacramento, CA. With a mission to protect communities by eliminating pollution caused by the extraction and disposal of natural resources, they focus on preventing waste at its source and holding producers accountable throughout a product's lifecycle. Established in 1977, Californians Against Waste is the nation's oldest, largest, and most effective environmental organization advocating for waste reduction and recycling policies and programs.

Their work includes the development of policies and incentives to motivate manufacturers to reduce waste and toxicity, design for recyclability, and increase the use of recycled materials. Through lobbying policymakers, they aim to implement and extend producer responsibility for the environmental impacts of products and processes. Additionally, they design programs and funding policies to provide the public with information and convenient opportunities for recycling and responsible waste management.

Californians Against Waste takes a proactive approach, emphasizing the concept of Producer Responsibility, which encourages manufacturers to internalize the environmental costs of their products. By driving sustainable practices, such as reducing consumption, using recycled materials, and designing for recyclability, they strive to create a thriving circular economy in California
