On the Justice of Global GHG Emissions Reduction Roadmap——An Evaluation and Revision to Professor Hu Angang's Global GHG Emissions Reduction Roadmap

　　Abstract: No global roadmap on the reduction of greenhouse gas (GHG) emissions can be viable without due consideration of international justice. The characteristic of climate change requires global roadmaps to respect two particular issues: environmental justice and development justice. In other words, the plan has to consider the equities between countries, between human beings, and between generations of the population. Taking Human Development Index (HDI) as the single criterion to measure the reduction burden of countries is therefore inadequate. To the very least, another two indicators-cumulative emissions per capita and climate change vulnerability-should also be included in the exercise. HDI, cumulative emissions per capita and climate change vulnerability indicate, respectively, equal rights of development, responsibility of historical emissions, and compensation to impacted countries of climate change. A more justifiable, acceptable, and implementable roadmap is to evaluate countries based on these three indicators. From the position of justice, China should take its corresponding responsibility to try to push forward global emissions reduction, while defending its own development rights. China's role in the global emissions is to strike a balance between international justice and its national development strategy.
