The European Patent Office has created a new classification scheme for green technologies and applications related to the mitigation of climate change. The new category, identified as Y02 in the ECLA classification, has two main subclasses:
* Y02C - CAPTURE, STORAGE, SEQUESTRATION OR DISPOSAL OF GREENHOUSE
GASES [GHG]
* Y02E - REDUCTION OF GREENHOUSE GASES [GHG] EMISSION, RELATED TO
ENERGY GENERATION, TRANSMISSION OR DISTRIBUTION [N1006]
Each subclass is further subdivided into dozens of sub-groups. There are about 17,000 patents classified in Y02 but more will appear in the coming weeks.
