Carbon credits can vary wildly in price, and while that can be attributed to any number of factors from the actual cost of materials and labor to run the project to the laws of supply and demand, there’s simply no excuse for the travel offset provider to not be completely transparent about their pricing structure and clear about how much is reaching the carbon project. Are there hidden “transaction fees” or “convenience charges”? For example, at nonprofit Cool Effect, more than 90% of each dollar donated goes directly to helping carbon-reducing projects, with only 9.87% to help cover administration such as payment processing, scientific documentation, and registration fees. If a travel offset provider is not transparent about where the money goes, who gets what, and how they fit into the process, proceed cautiously.
