Blockchain's environmental impact is a critical concern. Proof-of-work (PoW) consumes vast energy, leading to high carbon emissions. But solutions like Proof-of-Stake (PoS) and layer-2 scaling promise reduced energy use. Innovations in renewable energy integration and carbon offset programs can mitigate blockchain's footprint. Let's move towards sustainable blockchain ecosystems.
