Strong climate policy is vital to tackling climate change, but even the best proposals can get watered down when lobbying occurs. This article analyses which interest groups lobby on EU climate policies and under which conditions these groups achieve their policy goals. We expect that both economic and political resources are important. Economic resources give groups the capacity to mobilise expertise, but an interest group’s success also depends on its congruence with public opinion, especially in a politicised area such as EU climate policy. To test our hypotheses, we focus on six EU climate policy issues for which we conducted expert surveys with lobbyists and a content analysis of 737 media statements in eight European news outlets, combined with Eurobarometer data. Our results show that interest groups with higher economic resources and with public opinion on their side are more likely to achieve their preferences on EU climate policy issues.

Carbon pricing has been the most prominent climate change mitigation policy for the EU since the launch of its emissions trading system (ETS) in 2005. Since then, the context of international climate policy as well as of the socio-political and economical context of decarbonisation has changed considerably. The 2015 Paris Agreement engages virtually every country unlike its predecessor, while non-carbon pricing policies have led to rapid cost reductions in renewables, even if other sectors (particularly in energy-intensive industry) have not seen similar developments. This paper examines how the role of carbon pricing in the EU climate policy mix has evolved from its beginnings as a means to help achieve modest targets under the Kyoto Protocol, to a policy instrument increasingly augmented by a wider policy mix aimed at reaching no net emissions of greenhouse gases by mid-century.
