|dc.description.abstract||This thesis, without trying to forget legal philosophy and jurisprudence,
analyses unilateral trade-affecting measures which might be applied by a
state or region (e.g. the European Union) to support/promote climate change
related policies and how measures could be applied so that the World Trade
Organization (WTO) and the United Nations Framework Convention on
Climate Change (UNFCCC) and related instruments will not end up on
collision courses but be able to act on the basis of mutual supportiveness.
Chapter 2 mainly focuses on measures which could be used to achieve
carbon leakage related goals. Chapter 3 and 4 then switch to the more fruitful
application of measures to achieve the UNFCCC objective in a realm of legal
principles and rules. Chapter 5 reconsiders possible future conflicts on the
basis of chapter 4 and also looks at related issues in the political area.
The thesis, inter alia, highlights the advantage not just to focus on doctrinal
conceptualization, argues that unilateral measures focusing on the UNFCCC
objective can in specific circumstances be compatible with the WTO
framework and highlights that conflicts between the WTO and the UNFCCC,
both subsystems of the international law system, can be avoided.
Furthermore, it also underlines that principles are not irrelevant in the political
area, an area which, on the basis of further political decisions, might help to
get even more sophisticated mutual supportiveness between the UNFCCC
and the WTO.||en
