Description
Summary:The development of environmental technologies and its diffusion across countries are of key importance for international environmental policy. This paper considers technologies in the area of glass-melting furnaces and glass burners, which are major contributors of NO x emissions. Using patents as an indicator of innovations and patent citations as a proxy for knowledge flows, the inducement of new environmental and non-environmental technologies and their diffusion within and across countries, patent applicant types and patent firm types are analyzed in relation to NO x -related environmental policy. We find that most environmental patents originate from the USA and Germany and are filed by a broad range of firms. Most knowledge flows take place within countries. Regarding cross-country flows, most environmental knowledge diffuses from US patents, which is likely to be a result of early strict environmental legislation in some areas of the USA.
