Consumption, innovation and the environment

Indicator of environmental technologies (ENV-Tech Indicator)

 

As a contribution to the OECD project on Environmental Policy and Technological Innovation (EPTI), this website is intended to share information and facilitate research on ‘environmental’ innovation using patent data.  The definitions of search strategies that are published are an outcome of extensive groundwork by many researchers, as well as patent examiners at the European Patent Office who have developed a ‘tagging’ scheme for a number of climate change mitigation technologies. For many areas, the underlying developmental work is still on-going but individual components will be made available as they are finalised.

 

To keep in mind when applying the search strategies:

  • The term ‘environmental’ technology is intended to be a reflection of the public consensus on the utility of certain technological approaches in reducing environmental impacts, as compared to available alternatives. Hence, by definition, the notion of which technologies are considered ‘environmental’ evolves over time. This may have implications for the relevance of the search strategies.
  • Patent classification systems (such as the IPC, ECLA, etc.) are updated regularly and new ‘tagging’ schemes are being developed. In addition, availability of patent data (coverage, degree of detail) is improving rapidly. This will have direct implications for the adequacy of the search strategies provided below.

 

Thematic Areas of the ENV-Tech Indicator

Pre-defined queries are available for download at OECD.Stat. Alternatively, the data can be accessed through OECDiLibrary.  Detailed patent search strategies for the identifaction of selected environment-related technologies (ENV-TECH) are provided.
