Blockchain’s carbon footprint is a hot‑spot debate. Proof‑of‑Work consumes megawatts, driving CO₂ emissions. The shift to Proof‑of‑Stake and Layer‑2 rollups cuts energy use by 99%. Green hard‑ware, renewable‑powered nodes, and carbon‑offset programs are emerging. Projects like Ethereum 2.0, Cardano, and Avalanche prove that security and sustainability can coexist.
