Mitigating CO<SUB align=right><SMALL>2</SMALL></SUB> emissions by adjusting the power generation mix in Taiwan

In this paper, we employ a multi-objective programming model to estimate the power generation mix trade-off between generation costs and CO<SUB align="right"><SMALL>2</SMALL></SUB> emissions in Taiwan. Eight policy scenarios are simulated and compared to the reference and base cases. The empirical results show that, for the electricity sector, CO<SUB align="right"><SMALL>2</SMALL></SUB> emissions in 2010 could be set at 120% of the 1990 level, by way of promoting cogeneration and gas-fired generation capacity. The estimated per unit mitigation cost of CO<SUB align="right"><SMALL>2</SMALL></SUB> emission would be US$358/ton. The policy implications are discussed and limitation of this study is also presented.
