More generally, Luxembourg has a positive record in meeting its international commitments (often of longstanding) for the conservation of nature and biodiversity (Chapter 4). Pursuant to that Protocol and the terms of the European agreement distributing the burden among the 15 member states of the European Union, Luxembourg undertook to reduce its greenhouse gas emissions by 28% below their 1990 levels over the period 2008-12. This is the deepest cut of any agreed by the 15 member states.
