Y02 TECHNOLOGIES OR APPLICATIONS FOR MITIGATION OR ADAPTATION AGAINST CLIMATE CHANGE
Description
Y02 encompasses technologies and applications designed to reduce greenhouse gas emissions or facilitate adaptation to climate change impacts across all industrial sectors and technical fields. This cross-sectional classification captures inventions spanning energy efficiency, renewable energy generation, carbon capture, sustainable agriculture, water management, and climate-resilient infrastructure—regardless of their primary technical domain. Y02 serves as a supplementary tag applied alongside primary IPC/CPC classifications to identify the climate-relevant aspect of an invention. Inventions may be classified here in conjunction with their core technical class (e.g., a solar cell receives both its primary semiconductor classification and a Y02 designation for its climate mitigation application).
Of 8 combined children, 0 exist in both systems.
8 codes are CPC-only extensions.
Note: 8 CPC extensions are marked as secondary classification only.
