I have difficulty believing the statement: "Does East Asia need to lower its growth to ensure that the environment doesn’t deteriorate further? No...". Moving to a lower GHG emission development trajectory requires incremental investments relative to a Business-as-Usual scenario. These increemntal costs act as a tax that will decrease economic growth over the near-to medium-term. All IPCC models show this as does the World Bank low emissions analysis for Poland. Presumably, over the longer-term the incremental economic impact would be positive when one takes into account the costs of adapting to climate change, but those benefits will largely benefit future generations: that and the free-rider problem is what makes climate change such a challenge.
