  • Doctor Who: Worlds Apart is a product licenced by BBC Studios to Reality Gaming Group (RGG), who handle the design and development of the game, including the minting of all NFTs.


  • Below is RGGs full sustainability plan for creating "eNFTs" which are both sustainable and environmentally friendly.



Non-Fungible Tokens, or NFTs, are digital assets encoded on a blockchain that represent ownership of a unique asset.


All NFTs operate on a blockchain network and all blockchain networks do use energy to operate. However, the amount of energy can vary considerably based on the blockchain being used and the steps taken by the company in charge of creating the NFTs. Our NFTs use a version of Ethereum technology.


Only around 1% of transactions on the Ethereum mainnet can be attributed to NFTs. Most of the energy used by Ethereum is based on the speculative worth of the currency, not on NFT trading.


How much an NFT impacts the environment depends very much on the technology behind the minting process. In 2017, RGG recognized the carbon cost of trading on the Ethereum mainnet and took steps to reduce our carbon footprint for every NFT traded through our network and games. One of the main changes we’ve already made is to establish our own sidechain.


Our sidechain has allowed us to create eNFTs, a more environmentally friendly NFT that use around as much energy for each minting as a standard online Visa transaction, far less than if we were operating on the Ethereum mainnet. This also gives our users no Ethereum gas fees, thereby further reducing energy use.



We’ll be integrating with Layer 2 networks, such as Polygon, which essentially allow us to handle more of the heavy lifting of a transaction off the blockchain. This reduces the carbon emissions from energy use as more of the work will be done on our data servers, which already use 100% renewable energy.


Once the layer 2 network has handled some of the work, it communicates with the layer 1 network (the original mainnet) all changes which are then verified as normal. Layer 2 networks reduce carbon footprint overall when compared to the mainnet. We plan to be launching this by August 2021.


The Ethereum network will also be moving from a “Proof of Work” to a “Proof of Stake” system within the next year, which will reduce the mainnets energy consumption by as much as 90% overnight.


Read on for more information on our “Game for Earth” eNFTs and our longer-term plan for creating a sustainable NFT ecosystem.


Our 2040 Vision
"Game for Earth" Restoration

By 2040 RGG will have a climate restoration footprint.

Our Game for Earth community makes a significant restoration footprint

In 2040, the more you play, the more you help restore our planet.

Our Roadmap


Pay it forward

  • • Up to 80% of the RGG transfer fee will be converted to "Game for Earth" partnerships and communities.
  • • All our servers used for any data transaction will be carbon neutral.


From a local footprint to a global leader.

  • • We'll be establishing contracts with global data centers that focus on renewable energy initiatives
  • • We'll establish partnerships for our Pay it Forward, "Game for Earth" initiatives
  • • We'll ensure that any digital card game will have a significantly lower carbon footprint than the physical versions.


Minimise our CO2 footprint in the blockchain.

  • • We've established our "Game for Earth" framework and roadmap.g
  • • We've chosen data providers and partners that use renewable energy solutions.
  • • We've developed our eNFT technology to use less energy compared to the Ethereum mainnet


We do not use GAS.

We do not use mining.

Our sites all run on data centres that use renewable energy sources.

At Reality Gaming Group, we work with Hetzner datacenters that produce zero carbon emissions.

• Hetzner Online use hydropower, provided via Energiedienst, a TÜV certified company. This generates green energy from 100 per cent CO2 free and environmentally friendly hydropower.

The power of our
"Game for Earth" eNFTs

RGG has decided not to use the energy intensive, "Proof of work" system for our eNFTs. That means all our eNFTs reduce the energy use associated with:

  • Mining •
  • Minting •
  • Bidding •
  • Cancelling Bids •
  • Sales •
  • Transfers •

We have also avoided emitting 211 KG of CO2e/kWH compared to a standard, proof of work NFT.

In fact, our "Game for Earth" eNFTS emit between 0.0001 to 0.001 KG of CO2e/kWH, utilizing our sidechain and our data centres backed up by renewable energy.

Going from a local footprint
to a global footprint

RGG Gaming is a growing company. We are about to reach one million players globally.

We've partnered with AWS for our data centres to help us scale as we continue to grow.

AWS is the largest corporate buyer of renewable energy in 2020 and 2021, driving renewable investments forward. AWS has a long-term commitment to 100% renewable energy that they aim to reach by 2025.

Pay it Forward
"Game for Earth"
Community & Partnerships

If we can encourage our large userbase to take small steps, we can make a greater impact on global restoration.

• In 2021 and 2022, we are focusing on establishing partnerships with brands that can help us make a global impact on the environment.

• Our goal is to transfer 50% of our transfer fee to these “Pay it forward” partnerships.

• By 2025, we hope to increase that amount to 80%
