Fostering arms control: The role of unilateralism

Climate change has taken centre stage in European and international politics. Since the second half of the 1980s, the EU has established itself as an international leader on climate change and has considerably improved its leadership record. The Union has significantly enhanced both its external representation and its internal climate policies. However, implementation and policy coherence, coordination of EU environmental diplomacy, an evolving international agenda, EU enlargement, and a still precarious EU unity remain major challenges. Shifts in underlying driving forces and advances of EU domestic climate and energy policies nevertheless support the expectation that the EU will remain a progressive force in international climate policy for some time.
