Measure D (The Alameda County Waste Reduction and Recycling Initiative Charter Amendment) was approved by Alameda County voters in 1989 with the goals of reducing waste, promoting recycling, and setting a path toward ambitious landfill diversion targets for the county. The measure takes a unique and comprehensive approach to waste reduction and environmentalism by addressing a wide range of topics with multiple benefits, from residential recycling programs to mitigating the effects of climate change, along with prohibiting incineration as a waste management solution in the county.

Measure D also established the “Recycling Fund,” a surcharge on solid waste disposed of in Alameda County which is collected by landfill operators. These funds, administered by the Recycling Board, total around $9.7M annually. StopWaste, on behalf of the member agencies, oversees many activities across the focus areas specified in Measure D, while half of the funds are disbursed to member agencies to support their local sustainability efforts.
