Climate change mitigation technologies
 Climate change mitigation technologies are
technologies aimed at controlling, reducing or
preventing the anthropogenic emission of
greenhouse gases.
 With a growing awareness of the possible
consequences of those emissions, there is
increased political and social pressure to invest in
continuing research into such technologies.
 Indeed, since the signing of the Kyoto Protocol in
1997 there has been a significant surge in
research and development and thus also of
patenting in the related fields.
Climate change mitigation technologies
The need for information

In order to make informed decisions a reliable, comprehensive
documentation of information is necessary:
–
–
–
–
–
–
–
Global coverage
Technical content
Industrial research and development
Historically complete
"Up-to-date" coverage
Reliable content
Easily accessible
Climate change mitigation technologies  Information
Combining expert knowledge

Approx. 3800 patent examiners provide highly specialised expert
knowledge in:
– technical disciplines
– patent classification
– information retrieval

Collaborating EPO, ICTSD and OECD identified relevant the technical
fields within climate change mitigation technologies

Expert group of examiners was set up to:
– develop new classification system
– classify patent publications according to the new scheme

Patents and Climate change mitigation technologies
A new classification scheme
Driving mechanisms in patenting
Patent information - esp@cenet
Existing classification schemes: IPC and ECLA
It has not always been easy to find sector-related information on patented
technologies using the existing patent classification schemes.
Here a view on the current International (IPC) and European Classification (ECLA):
The eight main IPC and ECLA sections
A
Human necessities
B
Performing operations; transporting
C
Chemistry; metallurgy
D
Textiles; paper
E
Fixed constructions
F
Mechanical engineering; lighting; heating; weapons; blasting engines or pumps
G
Physics
H
Electricity
IPC: approx 70.000 codes; ECLA: approx 138.000 codes
New classification scheme  IPC and ECLA
A new classification scheme: Y02
 Because patent documents relating to climate change mitigation
technologies can be found in so many areas of technology, they do not
fall under one single classification section
 Climate change mitigation technologies as new, emerging technologies
develop very quickly
 New tagging scheme, similar to ECLA providing easy access to the
general public to climate change mitigation technologies
 Already online:
Y02C
Greenhouse gases – capture or storage/sequestration or disposal
Y02E
Greenhouse gases – emissions reduction technologies related to energy
generation, transmission or distribution
