ABSTRACT
The first question addressed the issue of the numbers Tomasz Z· ylicz used in the table ‘Quantified marginal costs of electricity production in EU27 in 2005-2010’. According to Z· ylicz, he chose those numbers for two reasons. First of all, in his opinion, they were good estimates, and he preferred them, because they were the numbers taken and acknowledged by the European Commission, and they originated from European Commission-funded projects. And secondly, the numbers corresponded with the case of China. According to official projections, greenhouse gas emission in China will quadruple in the next 50 years if co-benefits are disregarded. In contrast, if co-benefits are taken into account, emissions will increase by 2.5. Although emissions would in that case be lower, they would still be much higher than they are right now. Therefore, Z· ylicz concluded, co-benefits could not be seen as an effective policy option to combat climate change.
