How much carbon does minting an NFT on Ethereum produce today?

Post-Merge Ethereum (2022+): minting an NFT costs approximately 0.001-0.01 kWh per transaction, equivalent to 0.0004-0.004 kg CO2e — essentially negligible. Pre-Merge (PoW) Ethereum minting used ~100-200 kWh per NFT — this criticism is now outdated.

Is NFT trading on proof-of-stake chains environmentally neutral?

Not zero, but very small. Ethereum PoS energy is ~0.01 TWh/year total. Divided by ~1 million daily transactions: 0.000027 kWh/transaction. Carbon impact is dominated by the energy source of validators (staked ETH holders' home computers).

What about Solana, Polygon, and other low-energy NFT chains?

Solana: ~0.0005 kWh/transaction (validators run high-performance hardware). Polygon PoS: ~0.0003 kWh/transaction. All modern PoS chains have negligible per-transaction energy vs Ethereum PoW historical data that drove 2021 NFT carbon controversy.
