Abstract
Green House Gases emission has induced global warming, which results in economic, social, ecological and other aspects of environmental problems over the past decades. The direction of Low-Emission Development Strategies then has become clear. However, in the past the issues of greenhouse gases and conventional air pollutants are considered two individual fields to be analyzed concerning the impact on the environment. Following the low-carbon strategy, the development of its technology and policy will not only reduce greenhouse gas emissions, but also can directly or indirectly lower the emissions of conventional air pollutants, improving air quality, and obtaining health benefits.
Taiwan''s current carbon emission from power generation sector accounts for over 60% of the overall emission.Additionally, the power generation sector exhausts a lot of conventional pollutants. This study used TWIEA model and AERMOD atmospheric dispersion model to establish Taiwan''s power sector health co-benefits assessment methods, and assess the existing carbon reduction strategies implemented in Taiwan. The more aggressive strategies in which the demand of electric power and power generation structure changes are evaluated as to whether the CO2 and conventional pollutants (SOX, NOX, PM10) emissions could be lowered. Then, this study analyzes the health co-benefits at urban and national levels.
The results show that under the existing carbon reduction strategies, we are unable to reach the target of carbon reduction in power sector in 2020, and PM10 emissions will be higher than those in 2005. The only way to reach the goal in 2020 and abate SOX, NOX, PM10 emissions is to adopt more aggressive strategies, which will obtain higher health co-benefits (relatively being improved by 15.6%, compare with the existing policy). In addition, the national total emissions and the national total health effects are not necessarily positively related, so using the county-level resolution to assess health co-benefits will be better than just using the national-level resolution. In conclusion, the implementation of more aggressive carbon reduction strategies would lead to higher degree of health co-benefits for cities in order as following: Taichung city, Kaohsiung city, Keelung city, New Taipei City, Changhua County and Yunlin County.
