This analysis by the Austria-based European Integration online
Papers (EIoP) identifies the conditions under which
the environmental policy choices of one country subsequently
affect the policy choices of others. Based on four case studies,
the paper demonstrates empirically how horizontal diffusion
processes accompanied by information and recommendations from
international organisations have led to the adoption of new
regulatory instruments in an increasing number of countries.
Especially within the EU, a typical pattern of diffusion
between individual member states and from the national to the
EU-level is leading to an EU-wide legal harmonisation of
environmental policies.
