Sustainability in crypto is no longer a vague promise, and the latest 2025 figures show just how far the industry’s energy narrative has shifted. From emissions estimates to renewable power usage, the data reveals a gap between how blockchains are marketed and what they actually consume. Let’s look at the specific statistics behind that tension.
