In order to accurately assign all emissions that are caused globally by a single company, the carbon content of products and services needs to be identified and tracked across the value chain (lifecycle approach). The carbon content of products, unprocessed products or intermediate inputs can be registered on a blockchain-based system to track the virtual content of imported or exported products, allowing regulators to comprehensively enforce action against climate change. For instance, emissions caused by the generation of power used by electric vehicles can be uniquely identified and allocated to each charging process.
