California does not have laws specifically directed at blockchain mining. However, regulation exists.
Both the California Environmental Quality Act (CEQA) and California Global Warming Solutions Act (AB 32) regulate environmental impact, especially about energy consumption and emissions, and impact mining operations.
Mining activities using energy-intensive proof-of-work systems may receive scrutiny if excessive carbon emissions occur. California encourages and promotes renewable energy, through legislative structure, with California’s Renewables Portfolio Standard (RPS).
This regulatory framework encourages blockchain mining operations to use renewable energy. While mining companies are not specifically regulated, environmental impact considerations under California law may lead to implementation of energy-efficient technologies like proof-of-stake consensus mechanisms.
