Key meetings have been co-hosted by groups like Rocky Mountain Institute, The Nature Conservancy, the Sabin Center for Climate Change Law at Columbia University and the R Street Institute. Ocean Recovery Alliance  has co-hosted two meetings to explore how CTCs might apply to the problem of plastic waste. These gatherings concluded that CTCs should be able to drive down costs and increase profits, not only for waste management and recycling operations, but also for products that reduce waste, accelerating an array of circular economy and source-reduction solutions.
