OECD Project*• Develop indicators of EST innovation to be
included in OECDSTAT – alongside indicators of nanotech, biotech and ICT
• Develop indicators of EST technology transfer and internationalisation of innovation (co-invention and knowledge spillovers)
• Analyse the determinants of EST innovation and international transfer empirically using econometric techniques
* Financial support from DG ENV, UK DEFRA, DE BMU, CH BUWAL, NL VROM gratefully acknowledged.

Areas Covered by Project• Air pollution control (stationary and mobile)• Water and wastewater treatment• Solid waste management, recycling and prevention• Noise control• Monitoring technologies• Renewable energy• ‘Clean’ coal (i.e. IGCC, CCS, FBC)• Fuel cells• Building and lighting energy efficiency• Hybrid/electric vehicles• Green chemistry • etc...

Structure of Talk
• Preliminary results on determinants of EST innovation:– Air pollution, water and wastewater, solid waste– Climate change mitigation technologies
• Preliminary results on determinants of EST transfer– Air pollution, water and wastewater, solid waste– Climate change mitigation technologies

Environmental Policy Design Characteristics• Stringency – how constraining is the environmental
policy target• Uncertainty – does the measure provide a consistent
(foreseeable, transparent & credible) signal to investors
• Flexibility – does it let the innovator figure out the best way to meet the objective
• Depth – are there incentives to innovate throughout the range of potential objectives
• Incidence – is the point of incidence of the policy directly on the externality or is it on a ‘proxy’ for the pollutant
• Legal status – is compliance with the policy mandatory or voluntary

Next Steps
• Finalisation of EST-innovation indicator(s) (ENV-tech) – to be included in OECDSTAT
• Further empirical analysis of determinants of EST innovation in different areas (e.g. ‘green’ chemistry, motor vehicles, climate change backstop technologies)
• Further empirical analysis of determinants of transfer of EST technologies
• Linking innovation data with micro-data (Orbis/Amadeus, CIS, PRTRs) to analyse economic and environmental effects of EST innovation
