About this data
Patent statistics and indicators are suitable for tracking innovation in environment-related technologies. They allow the assessment of countries' innovation performance as well as the design of governments' environmental and innovation policies. This dataset presents data on shares of co-inventions and on shares of inventors’ collaborations across the OECD area and elsewhere, in environment-related technologies, using inventors’ country of residence.
