The Ripple Effect: The EU-ETS and the Global Spread of Green Technology Chaire Economie du Climat / EDF R&D / Université Paris Nanterre, France The EU Emissions Trading System (EU ETS) is the European Union's flagship instrument for achieving carbon neutrality by 2050. Because the policy applies to a subset of economy-wide emissions, a central question is whether and how low-carbon technological change extends beyond the set of regulated activities. This paper documents a sharp increase in low-carbon patenting among firms that are not directly regulated by the EU ETS and examines whether this pattern is systematically related to these firms' positions in European value chains connected to EU-ETS-regulated production. Using sector-level evidence and mapping innovation to value-chain exposure, we show that the growth in low-carbon patenting among unregulated firms is concentrated in sectors that are upstream or downstream of regulated production networks. Methodologically, we highlight that measuring exposure using the total coefficients matrix---rather than the direct coefficients matrix---can alter qualitative conclusions relative to common approaches in the literature. | |
