CSR commitments

The NFT stamp, in line with La Poste Group's social and environmental commitments

The commitment to ethical and frugal digital is now enshrined in La Poste Group's articles of association, as is the commitment to reduce greenhouse gas emissions across the board. As a logical consequence, Philaposte has implemented concrete actions to ensure that the NFT stamp project is consistent with La Poste Group's social and environmental commitments:

Action 1: printing the physical stamp at the Boulazac site (Dordogne)

ISO14001 certified since 2007, the Boulazac printing plant is equipped with 2,000 photovoltaic panels to cover part of its energy needs, producing 1 million kWh/year. The plant has held the FSC® and PEFCTM labels since 2012. The printing plant implements processes to reduce cardboard and paper waste (less paper waste) and to recycle it.

• 2000 solar panels
• 97% of paper from sustainably managed forests
• 88.94% of waste recycled

Action 2: responsible delivery with Colissimo

Physical stamps are delivered via Colissimo, a pioneer in low-carbon delivery in France.

• 90% of national deliveries optimised thanks to storage
• 70,000 tonnes of CO2 avoided by 2025, with the widespread use of "bulk tidied" lorries

Action 3: inclusive purchasing, without cryptocurrency

NFT stamps are sold in euros, unlike many NFT works of art, which are sold in crypto-currencies. The aim: an inclusive purchase open to everyone, even those who are not comfortable with technology. The aim is also to secure the purchase, avoiding the fluctuations seen on the crypto-currency market.

Action 4: Choosing an energy-efficient blockchain

Philaposte has chosen to work with Tezos, one of the pioneers of blockchain in France. Tezos uses the POS (Proof of Stake) technique to validate transactions in the blockchain. This technique is very energy-efficient: the total carbon footprint over the year is estimated by PwC to be that of 17 citizens of the world. According to the same source, Tezos' annual energy consumption is equivalent to 0.001 TWh (compared with 26 TWh for the POW (Proof of Work) technique, used by the Ethereum blockchain until 2022).

90 to 99% less energy consuming

Explanation:

Remember that the blockchain is first and foremost a network of interconnected computers. Together, these computers have the task of registering ("mining" in the jargon) the NFTs in the chain, as well as all the associated transactions (buying, selling). The owners of the computers (the "miners") are financially rewarded according to the number of transactions entered. There are several systems for determining which miners are rewarded:

• The POW (Proof of Work) system rewards the fastest 'miner'. In practice, all the computers do the calculations. This system requires phenomenal computing power. It consumes a lot of energy and is often criticised by opponents of blockchain.

• The POS (Proof of Stake) system is based on trust. The lucky paid "miner" is first drawn at random. It then performs the calculations that enable it to be registered on the blockchain. Logically, this system consumes much less energy.

Action 5: An eco-designed and inclusive platform

The nftimbre.com website is eco-designed to limit its carbon impact. It has an overall score of C on EcoIndex. Of course, we are constantly working to improve its performance. The site is also designed to be accessible to all, easily usable for all audiences, including people with disabilities.

Action 6: A tool to calculate the carbon footprint of your NFT stamps

After the first purchase of an NFT stamp, an application will allow you to track the carbon impact of your NFT stamps in real time via the Carbonz tool

Delivery, printing, registration in the blockchain... the carbon footprint is measured at every stage
