To further incentivize customers to recycle their used Rebecca Taylor pieces, the brand will donate 50% of the proceeds to Cool Effect, an organization working to reduce carbon emissions. “We’re focusing specifically on helping families build biogas digesters and clean cookstoves which will help transform harmful global warming emissions into clean, renewable energy in China,” Sullivan explains. For those of you who don’t regularly read up on carbon emissions (or its very specific terms), biogas digesters are basically tanks that digest organic materials to produce biogas, a natural energy source, according to GLW Energy. “Cool Effect has reduced over 1 million tonnes of carbon in less than four years,” says Sullivan.
