# Green Proofs as a Service Green Proofs as a Service allows green start-ups and enterprises alike to create Proof of Concepts for demonstrating emission reduction savings through the creation of ready-to-go registries. You can configure your registry to accommodate your requirements and you don't have to be a developer to do it. Examples of emission savings products include: 1. Sustainable Aviation Fuel ( marking the difference between regular fuel and low emissions fuel) 2. Maritime Sustainable Fuel ( marking the difference between regular fuel and low emissions fuel) 3. Green Proofs for Bitcoin ( demonstrating the use of renewables vs fossil fuel energy) 4. Your next project can be showcased here.
