Definition ∞ Carbon-negative technology refers to technological processes that remove more carbon dioxide from the atmosphere than they release. These systems aim to actively reduce atmospheric greenhouse gas concentrations, moving beyond carbon neutrality. Examples include direct air capture, enhanced rock weathering, and certain bioenergy systems with carbon capture.
Context ∞ The cryptocurrency industry’s energy consumption has intensified interest in carbon-negative technology, particularly for proof-of-work blockchains. Efforts are underway to integrate such technologies into mining operations or to offset energy usage with carbon removal credits. A key discussion revolves around the feasibility and scalability of these solutions to mitigate the environmental impact of digital asset validation processes.
