Decarbonisation is the systematic reduction of carbon dioxide and other greenhouse-gas emissions from an activity, organisation or economy, ultimately toward net zero. It combines energy efficiency, electrification, renewable energy procurement and removal of residual emissions, often guided by science-based targets. For energy-intensive systems such as blockchains it is the pathway to credible carbon-neutral operation.

- Strategies span avoiding emissions through efficiency, switching to clean energy, and removing or offsetting unavoidable residuals. Credible decarbonisation prioritises absolute reductions aligned to climate-science pathways over reliance on offsets.
