Mitigation of air pollution and climate change in China
Workshop in Oslo 17 – 19 October 2004Financial support by

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.

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?
Local Pollution and Climate: the Importance of Co-
benefitsBeijing, 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).
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.
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?
Energy (commercial) consumption in China 1965 -
2003
China is the country with the largest CO2 emissions after the USA.Per capita emissions about 1/7 of those in the USA

Gaia: Organisms and their environment evolve as a single, self-regulating system.

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.
