The Fifth IGES White Paper (WP V), entitled “Greening Integration in Asia: How Regional Integration Can Benefit People and the Environment”, discusses how regional integration efforts in Asia and the Pacific could be a driver for green economy and sustainable development. The current regional integration processes in the region are focusing on economic integration through trade and investment liberalisation. WP V tries to invite an active discussion on what kind of regional integration amongst Asian nations would be beneficial, not only in the short term and from the narrow viewpoint of national interests, but from a wider sustainability perspective. The publication is based on the results of a number of IGES studies related with regional cooperation and integration in Asia and the Pacific. In this session selected chapter authors will share their key messages and discuss with the audience how greening integration in Asia can be realised.
