What role could a Parliamentary Assembly play in climate policy?

A different political dynamic would exist in a Parliamentary Assembly compared to current UN intergovernmental bodies and conferences. The members predominantly would be independent, many would belong to national opposition groups and they would organize in cross-national political groups. An assembly and its members thus would be in a better position to develop common global or multilateral solutions and to give less consideration to purely particularist national interests. Delegates would have more legitimate authority in representing the economic concerns of their constituents in regards to climate change remedies. Even as an advisory body, such recommendations and proposals from the assembly could carry significant moral weight and pressure national governments to adopt globally sustainable solutions.
