A life cycle analysis was performed for the assessment of the environmental performances of three existing Italian power plants of comparable nominal power operating with different sources of renewable energy: Geothermal, solar, and wind. Primary data were used for building the life cycle inventories. The results are characterized by employing a wide portfolio of environmental indicators employing the ReCiPe 2016 and the ILCD 2011 Midpoint+ methods; normalization and weighting are also applied using the ReCiPe 2016 method at the endpoint level. The midpoint results demonstrate a good eco-profile of the geothermal power plant compared to other renewable energy systems and a definite step forward over the performance of the national energy mix. The Eco-Point single score calculation showed that wind energy is the best technology with a value of 0.0012 Eco-points/kWh, a result in line with previously documented life cycle analysis studies. Nevertheless, the geothermal power plant achieved a value of 0.0177 Eco-points/kWh which is close to that calculated for the photovoltaic plant (0.0087 Eco-points/kWh) and much lower than the national energy mix one (0.1240 Eco-points/kWh). Also, a scenario analysis allowed for a critical discussion about potential improvements to the environmental performance of the geothermal power plant.

Environmental performance evaluation is a multi-attribute evaluation problem. The determination of indicators’ weight is the key problem in the multi-attributes evaluation. This paper set up an evaluation model based on multi-attribute variable coefficients and fuzzy pattern recognition aimed at a thermal power plant. The model gives full play to the advantages of the subjective and the objective coefficients and enables itself to alter the coefficients in accordance with the specific indicator values of evaluated objects, hence, bringing the function of performance evaluation into full play.

Background – PT Pembangkitan Jawa-Bali (PT PJB) is a subsidiary of PT PLN (Persero) which participates in the Business Performance Rating Program in Environmental Management (PROPER) organized by the Ministry of Environment and Forestry (MoEF) of the Republic of Indonesia based on Ministry of Environment Regulation No 06 year 2013. As a subsidiary of PT PLN (Persero), PT PJB establishes management contracts  which  aim to get a Gold PROPER rating from the MoEF. Even so, the company still has some challenges as it encounters several problems of managing CSR internally. As a first step, PT PJB, especially in CSR Department, has made improvements in its organization by implementing a PROPER-based performance appraisal system in managing CSR in all PT PJB Power Plants. Purpose – Examining the phenomenon which has been occurring for the past several years, researcher decided to conduct observations and interviews. This study tries to explain descriptively how changes have been designed and implemented through the "Performance Management Model" approach. Design / Methodology / Approach – This study is a qualitative field research. The data for this research were collected through observation and interviews. Focus interview were about CSR concept, Company’s goal and target, integrated CSR management to Company’s vision and mission, CSR management problems in different area, and social-environment national issue. Data collected were then analyzed using content analysis method. Result and Discussion – Positive impacts were found after the implementation of change in management model at the CSR Department, such as maturity level in CSR management increased, charity program decreased, and human resources capability increased. The result that One of the company’s Power Plants, Paiton Power Plant, won the Gold PROPER rating. It could be considered as the biggest achievement since the company became the only power plant in the PLN (Persero) Group which first obtained a Gold PROPER rating. Conclusion –  The establishment and implementation of PROPER-based governance system would not be optimum if it did not involve employees (Head Department, Managers, Supervisors, and staff) mastering in CSR. Research Limitations – This study has limitations in reference, namely the limited researches and previous journals on organizational change, particularly in the management of its CSR activities, which researcher found as reference material.

The objectives of this research is to examine the role of environmental performance in the relation between carbon emissions disclosure and firm value. A measurement tool using content analysis method to measure carbon emissions disclosure that adopts a checklist from the Carbon Disclosure Project (CDP). Firm value is proxies with Tobin's Q, while environmental performance is assessed based on the results of the environmental management performance appraisal program (PROPER). Sample of this study using 34 companies that listed on the Indonesian Sharia Stock Index (ISSI) from 2014 to 2019. Moderated regression analysis (MRA) is used to test the hypothesis. The results indicate the carbon emissions disclosure has a positive and significant effect on firm value. This research also found that there is an evidence that environmental performance can strengthen the relation of carbon emissions disclosure to firm value, due to the company's efforts by participating in the PROPER program is a form of corporate responsibility in an effort to reduce the impact of environmental damage arising from the company's operational activities which have been responded positively by investors.
