The main reasons brought by the appealing party were the high CO2 emissions that will lead to worsening of the population health in the region as well as global warming effect and increased dependence on the imported coal. Furthermore, it will not allow Croatia to meet the conditions imposed by EU regarding the decrease of greenhouse gas emissions by 2050. This may affect even the economic side of the project as it may lead to the purchase of additional greenhouse gas emissions credits under the European Union Emissions Trading Scheme. Prof.dr.sc Enco Tireli, a local expert, who worked for HEP for more than 20 years and was also construction manager for Plomin B, confirmed the fact that the project will not be profitable due to the additional payment for CO2 credits. According to EU goals, Croatia's total emissions will be in the range between 1.566 and 6.264 million tonnes Carbon dioxide equivalent (CO2eq) annually, while only Plomin C would emit 2.644 million tonnes CO2eq. Thus, there will be no reserves of CO2 emissions left for other sectors as industry and transportation.
