tailieunhanh - Integrated Assessment of Black Carbon and Tropospheric Ozone

At the end of this year, governments will gather in Durban, South Africa, for the next round of United Nations negotiations to advance global action on climate change. In June 2012, the UN Conference on Sustainable Development (Rio+20) will seek to secure new and comprehen- sive commitments to sustainable development. This publication aims to support the efforts leading up to Rio+20, as well as the activities, processes, commitments and partnerships that flow from it. By highlighting the nexus among climate change risks and opportunities, sustainable development and climate change adapta- tion, Adapting for a Green Economy provides useful guidance to business leaders. | World Meteorological Organization Integrated Assessment of Black Carbon A complete elaboration of the topics covered in this summary can be found in the Integrated Assessment of Black Carbon and Tropospheric Ozone report and in the fully referenced underlying research analyses and reports.
