Bitcoin mining is undergoing a transformation towards becoming carbon negative, with 6% of miner CO2 emissions already being offset through methane capture mining techniques. CH4 Capital plans to invest $50 million in methane capture mining, potentially increasing the mitigation figure to 17%. The carbon footprint of Bitcoin mining could be completely neutralized with an investment of approximately $450 million. The adoption of off-grid renewable energy sources and greener grids by miners has contributed to the reduction in emissions. The CH4 Capital Landfill Gas BTC Mining accelerator aims to convert environmental pollutants into power for Bitcoin mining. MIT and KPMG have published research on Bitcoin mining and its environmental impact, providing hope for a more sustainable future.
