The Sandbox is and has always been about striving to provide the best experience for users interacting with our platform. As environment friendliness for NFT applications has always held a particularly important place for us, the decision to move to a layer 2 solution, such as Polygon’s, became evident.
Let’s take a look at where Polygon — with its Proof of Stake (PoS) consensus mechanism — ranks in terms of its ecological footprint.
As per estimates, the biggest Proof of Work (PoW) blockchains can consume a yearly quota of anywhere between 35–140 TWh of electricity, with a continuous draw of anywhere between 3–15 gigawatts (GW) of electricity. To scale this 1 GW could realistically power 300,000 homes, light up 110 million LEDs, or power Doc Brown’s Delorean to travel back to the future with 1,21 GW. That represents a lot of energy consumed.
By contrast, Polygon’s validators consume approximately 0.00079TWh of electricity yearly with an approximate continuous draw of 0.00009GW.
With The Sandbox set to integrate Polygon for the VoxEdit NFT (non-fungible token) builder for building voxel game assets, the Marketplace for buying and selling assets, and the Game Maker tool, the speed and gas cost efficiency of The Sandbox is going to massively improve.
Concretely, what does this implementation mean for The Sandbox? Transferring an NFT from one user to another would approximately equal sending an email; selling any type of NFT (ASSET, LAND, etc) will use less energy than it would take to stream a 2 hour-long movie, and buying a parcel of LAND would now be like doing 30 Google searches.
Under the new efficient technology powered by Polygon, NFT minting will generate less than 1% of the carbon emission that it currently produces on the standard Ethereum blockchain.
This commitment to addressing the environmental impact has led The Sandbox to partner with Nori, who was part of the 2019s Techstars Sustainability program.
Nori coordinates the creation and administration of carbon removal projects, starting with regenerative agriculture projects that store carbon in the soil thanks to the large co-benefits including water retention and improvements to soil health and quality. Through working with Nori, The Sandbox will be responsible for a number of Nori Carbon Removal Tonnes (NRTs), each NRT representing a tonne of CO2 removed from the atmosphere and stored in a terrestrial reserve. Check Nori Sandbox Certificate of Carbon Removal.
In addition, The Sandbox also purchased 200 tonnes of nature-based CO2 offsets from Offsetra. You can visit The Sandbox’s profile page to view the impact and proof of certification.
The Sandbox wants to set the standard for transparency and best practices in the world of NFTs and encourages a healthy discourse about the tools that can be used to reduce environmental impact and the uses of NFTs and blockchain technology.
200,000kg CO2 is equivalent to:
🍔 50,000 cheeseburgers
🐄 90 cows (annual emissions)
🚙 500,000 miles of driving (average passenger vehicle)
💳 15,698 Ethereum transactions.
Tree Growing: The Sandbox is collaborating with WeForest, a tree-growing charity, once again. In 2014 the mobile version of The Sandbox and WeForest had already partnered to plant 9,000 Mangrove trees in Madagascar.
This time The Sandbox team is committing to donate 1% of the proceeds of its virtual LAND sales in 2021 to grow trees in carefully selected projects and only through trusted charity organizations that have expertise in the field. The Sandbox will engage with more foundations that center around nature protection to pursue its significant effort to make a real impact in the physical world.

The Sandbox is also considering other options that are currently in development if a more efficient technological solution were to appear.
As a pioneer in the blockchain gaming space, we’re taking steps to mitigate energy usage by up to 99% now, and will continue to look for additional technical solutions.
