1. Mitigation of air pollution and climate change in China Workshop in Oslo 17 – 19 October 2004 Financial support by The Research Council of Norway & Norwegian Ministry of Foreign Affairs

2. Robert Angus Smith Our forerunner from the 19th century The injury thus done to trees, hedges, crops and pasturage is enormous, in addition to the mischief inflicted upon human health and comfort………… Dr. Smith’s investigations show that it is not only possible to reduce these exhalations, but actually economical to do so. Noxious vapours affect vegetation along the river Tyne, 1875

3. ESF EXPLORATORY WORKSHOP (co-sponsored by the Research Council of Norway and the Norwegian Agency for Development Co-operation): Atmospheric pollution effects on local, regional and global scales – an integrated approach.

6. Some measures and their effects

7. From the report from the 2002 workshop: Exposure estimates  Improvements are necessary on all scales - from indoor to regional; importance of site and height of emission should be emphasized. Dose-response relationships  Includes effects on humans, vegetation and materials. There is a particular lack of information from developing countries.  Effects of particles, including black carbon, both as part of the climate system and as air pollutant, are particularly important. Valuation  Valuation of health effects and natural ecosystems should be focused.  Willingness-to-pay studies in developing countries are highly needed. There is a need for improved knowledge in a number of areas, including: To what extent are the results of our work implemented? How to increase penetration of results in policy and industry?

8. Local Pollution and Climate: the Importance of Co-benefits Beijing, November 13th – 14th, 2003 Organized by:  PRCEE ( Policy Research Center for Environment and Economy, State Environmental Protection Administration, China).  ECON (Center for Economic Analysis, Norway), and  CICERO (Center for International Climate and Environmental Research, Norway).

9. Some conclusions from the Beijing workshop Co-benefits for China are very significant and not to be ignored. Environmental improvement, as well as energy saving and new and renewable energy development, should be put into the priority list for GHG-reduction in China. China should support CDM stronger with consideration of co-benefits. China should have more active air pollution programs and ecological restoration programs with consideration of co-benefits. GEF as well as other multilateral funding mechanisms should pay non-Annex I countries’ for GHG reductions, at least cover the incremental costs. Countries’ emission baselines should be adjusted taking co-benefits into consideration.

10. Mitigation of air pollution and climate change in China Goal: Elucidate advantages (and problems) in considering mitigation of air pollution and climate change in an integrated way through discussing results in two important research areas in an interdisciplinary forum. Two topics will be included:  Emissions from the household sector affecting climate and possible co-benefits.  Environmental impacts in a macro-economic setting. Why focus China?

11. Energy (commercial) consumption in China 1965 - 2003 China is the country with the largest CO 2 emissions after the USA. Per capita emissions about 1/7 of those in the USA Energy sources 2003

12. Bjørn Lomborg: Copenhagen consensus The goal of the Copenhagen Consensus project was to set priorities among a series of proposals for confronting ten great global challenges. The Skeptical Environmentalist Measuring the real state of the world

13. Bjørn Lomborg: Copenhagen consensus Very Good  1 Diseases: Control of HIV/AIDS  2 Malnutrition: Providing micro nutrients  3 Subsidies and Trade:Trade liberalisation  4 Diseases: Control of malaria Bad  14 Migration: Guest worker programmes for the unskilled  15 Climate: Optimal carbon tax  16 Climate: The Kyoto Protocol  17 Climate: Value-at-risk carbon tax

14. Gaia: Organisms and their environment evolve as a single, self-regulating system. James Lovelock Nature, 426 (2003), 769-770 Perhaps its [Gaia’s] value lies in its metaphor of a living earth. Which reminds us that we are part of it and that human rights are constrained by the needs of our planetary partners.
