Y02C CAPTURE, STORAGE, SEQUESTRATION OR DISPOSAL OF GREENHOUSE GASES [GHG]
Description
Y02C covers technologies and processes for capturing, storing, sequestering, or disposing of greenhouse gases (primarily carbon dioxide, methane, and nitrous oxide) to mitigate climate change. This classification includes carbon capture and storage (CCS) systems, direct air capture technologies, geological sequestration methods, utilization of captured CO2 in industrial processes, and destruction or conversion of greenhouse gases into stable compounds. It encompasses applications across power generation, industrial manufacturing, waste treatment, and dedicated capture facilities, but excludes general emissions reduction through energy efficiency or renewable energy transition, which fall under other Y02 subclasses.
Of 1 combined children, 0 exist in both systems.
1 codes are CPC-only extensions.
Note: 1 CPC extensions are marked as secondary classification only.
