According to a recent GSMA report [20], all major operators have set up targets to reduce carbon intensity from 50% to 70% in next couple of years with the ultimate goal of achieving net-zero emissions. Though 5G NR offers improved energy-efficiency, new 5G use cases and the wider adoption of 5G NR will result in an increased number of sites and antennas, which may offset these gains if left unmitigated. To address this, cut down on emissions and increase network efficiency, operators have an interest in powering their network using renewable energy sources to reduce emissions and enhance network efficiency. It is also important for operators to understand and track the proportion of energy consumed in their networks that is sourced from renewable sources, which can be made available to customers and authorized third parties.

The network operator R has deployed a 5G network "N" and is promoting its services as "Green Energy". This is due to the fact that 60% (this could be any % number, 60% is just provided as an example) of the energy required for network operations is sourced from renewable resources. The government is providing tax credits to companies using renewable energy, and R provides its customers with information about the proportion of renewable energy consumed and renewable energy certificates (RECs) [21], if applicable. Company X, which places a high value on environmental sustainability, has subscribed to R's Green Energy services requesting for minimum ratio of renewable energy used for the communication service. R provides X with a dedicated slice (or NPN) guaranteeing this minimum ratio. R provides periodic reporting information regarding the percentage of renewable energy consumed. As a result, X is eligible to receive tax credits from the government for its purchase of renewable energy.

1. Customer X subscribes to the 'Green Energy' service for its warehouse, provided by operator R.
2. The warehouse is served by a limited "X" number of base stations and the core network could be hosted in a central cloud location that is powered by renewable energy.
3. Operator R provides a dedicated network slice that utilizes a minimum 80% renewable energy for customer X's NPN at their warehouse. The 5G system will not actively monitor the dedicated resources for energy consumption.
4. Operator R periodically calculates statistics about the ratio of renewable energy consumption of the network elements used within the customer X's dedicated slice (or NPN).
5. Customer X receives periodic report every month regarding the ratio of renewable energy consumption from Operator R.
6. Operator R supplies customer X with the requested information.
7. Customer X can advertise that it is committed to a "Green Energy" and is using 80% renewable energy for the dedicated communications service at its warehouse. Additionally, Customer X can also claim tax credits from the government.

Customer X can get a dedicated network slice or NPN utilizing a minimum ratio of renewable energy used by the network serving its warehouse. Customer X receives a periodic report on the ratio of renewable energy used by the network serving its warehouse.

None.
