The European transition to green economy is based on long-term strategies. The Europe 2020 Strategy was launched in 2010 in order to promote smart, sustainable, and inclusive growth in the region. Later, the ambitions regarding this strategy were followed by the Green Deal and Sustainable Development Goals. Now, the effort of countries towards the green economy is even more relevant than ever because of the context of today's global energy crisis and economic uncertainty due to many challenges such as the COVID-19 pandemic or Russia invasion of Ukraine. This paper seeks to assess the countries' achievements in seeking climate change and energy targets of the Europe 2020 Strategy by applying the innovative multi-criteria decision-making (MCDM) technique. The kernel-based comprehensive assessment (KerCA) method was applied for the calculations of the progress achieved and countries' rankings. It allows to evaluate countries' achievements and compare them using the mathematical models. The analysis of the national target implementation in the countries allows to determine the compliance of countries with their commitments and liability towards other countries and the European Union (EU). An analysis of the implementation of the strategy can serve as a guide to further develop climate change and energy policy in the region. Furthermore, the added value of the article is systematic overview of scientific studies proposing different methodologies for the analysis of target implementation at the whole region level. The novelty of this paper also relies on the approach, which considers not only the level of achievement of the target, but also assesses the excess. [ABSTRACT FROM AUTHOR]

The penetration of renewable energy is one of the main challenges for sustainable energy development. Local governments across the European Union commit to development and implementation of the Sustainable Energy (and Climate) Action Plan. This paper focuses on the case of Lithuania—a Central and Eastern European country. Almost one-third of Lithuanian municipalities have joined the Covenant of Mayors and prepared the plans that include SWOT analysis. However, there is a lack of information on how those plans contribute to climate change mitigation and sustainable energy development. This study identifies the links between key policy financial instruments, increasing energy efficiency. The Strategic Action Plans aimed at reducing GHG emissions and energy consumption in Lithuanian municipalities are analyzed. The challenges in promoting the renewable energy generation in Lithuanian rural regions are discussed. Moreover, the importance of strengths, weaknesses, opportunities, and threats identified is elicited at the local level. The study uses a combination of methods, such as expert surveys and SWOT analysis, that complements the tools used for regional energy climate planning and allows for overarching analysis. The expert survey shows that priority is given for renovation of buildings and modernization of energy infrastructure, making them more sustainable and more energy efficient. The results also show that, in the case of Lithuania (and possibly elsewhere in the post-Soviet countries), conditions and opportunities should be created beforehand to increase energy efficiency. Once this is achieved, the policies should focus on energy transition by switching to sustainable energy resources. [ABSTRACT FROM AUTHOR]

Energy policy affects the functioning of the economic and financial systems of countries worldwide. This paper provides a theoretical overview of the economy–energy nexus and discusses the particular cases of the energy policy dynamics amid the sustainability goals. This paper integrates multiple perspectives on the energy–economy nexus, with a particular focus on the energy trilemma, 4As of energy security and PESTEL approach. This allows the development of a comprehensive framework for the analysis of energy security and the sustainability interaction. A review of manifestations of the different dimensions of energy security and sustainability is carried out to identify the most topical facets of the issue. Then, the cases of the selected European Union countries (Ireland, Greece, Denmark and Lithuania) are presented to highlight the effects and features of the recent energy policy changes there. Indeed, these countries apply a PSO levy mechanism on electricity tariffs and are diverse in their geopolitical situation, economic development, geographical situation and energy dependency level. The analysis of the situations of such different countries applying the PSO levy mechanism makes it possible to perform a broader and more in-depth assessment and comparison of electricity tariff regulations. Thus, the developed theoretical model is applied to identify the major outcomes of the energy policy regimes (with a focus on tariff regulation) in the selected countries. [ABSTRACT FROM AUTHOR]

This paper suggests that the efficiency of a system (decision-making unit) and its subsystem cannot be properly measured using a two-stage data envelopment analysis (DEA) model either in cooperative or non-cooperative evaluation. Indeed, the existing methods subjectively determine the status of the subsystems in the whole system. The two-stage DEA models, either cooperative game or non-cooperative game, are used to analyze the environmental efficiency. However, when the actual relationship between the two subsystems is inconsistent with the subjective relationship assumptions, the overall efficiency of the system and the efficiency of each subsystem will be biased. The conventional two-stage DEA models require predetermining the relationship between the subsystems within the system based on the subjective judgment of the decision-maker. Based on this, this paper proposes a three-step method to solve the two-stage DEA. First, the position relation among subsystems is determined according to the optimal weights through the model. According to the status relationship among subsystems, the decision units are grouped, and the two-stage DEA model of cooperative game or non-cooperative game is used to analyze the efficiency in each group. This method reduces the subjectivity of decision making and analyzes the efficiency of each decision unit applying the most appropriate two-stage DEA model to find the source of inefficiency. Finally, this paper verifies the rationality and validity of the method by analyzing the water use efficiency of industrial systems in China. It is found that most regions in China value economic development more than environmental protection (as evidenced by the DEA weights). What is more, the method proposed by the paper can be generalized for any two-stage DEA problem. [ABSTRACT FROM AUTHOR]

Though there are areas of climate change mitigation linked to household's energy consumption having huge greenhouse gas (GHG) emission reduction potential as energy renovation or installation of micro generation technologies using renewable energy sources, these GHG emission reduction potentials are not realized so far. The main input of the paper is to overcome this gap and to provide a systematic review of the main barriers of climate change mitigation behavior linked to energy consumption in households and to develop policies to overcome these barriers. The main policies and measures to reduce GHG emissions of energy combustion in households are promotion of renewable energy consumption and energy efficiency improvements however, these policies have been not successful in overcoming some important barriers of climate change mitigation in households. The empirical evidence of behavioral failures is deepened in this paper and the correlation between market barriers, unsuccessful climate change mitigation policies and behavioral and psychological barriers is provided based on systematic literature review.

The paper deals with the problems linked to the energy renovation of multi-apartment buildings and developed a case study in Lithuania with the aim to assess the household's willingness to pay for energy renovation and to define the main barriers preventing the households from making decisions to renovate their apartments in residential buildings. Energy renovation provides huge energy savings and greenhouse gas emissions reduction potential and though policies and measures exist to promote large scale energy renovation, there are still many barriers and the pace of energy renovation is still very slow, especially in new EU member states and former Soviet Union members. These countries have inherited old, energy inefficient residential buildings from their Soviet past, and their inhabitants are locked in energy poverty because of their inability to renovate their apartments. This paper analyzed the current situation in the selected country and presents the results of a case study on willingness to pay (WTP) for energy renovation in Lithuanian residential buildings. The survey of 104 Lithuanian households living in unrenovated multi-flat buildings was conducted. The 39 multiple choice questions were asked in order to define the main barriers and drivers of energy renovation. The main results of this pilot study indicated that there are several important organizational and economic barriers for energy renovation in multi-flat buildings and current policies and support schemes have not addressed them in a proper way. The high heating bills and low heat comfort in apartments were the main drivers of energy renovation decision-making for households, however, inadequate state support, reluctance to take a loan due to low income, and inability to make collective decisions on renovation due to the lack of cooperation and housing association were the main barriers that prevented them from this step. New innovative schemes like the Energy Service Companies ESCO model with consolidated billing can be applied to address the identified barriers. [ABSTRACT FROM AUTHOR]

A wide range of climate change mitigation policies have been developed around the world and these policies have become one of the major concerns, however there is still debate among scientists about what are the main external benefits and how to account for them and prepare effective climate change mitigation policies that might be widely accepted by society in general. One of the main ways to assess external benefit of climate change mitigation in energy sector is to conduct Willingness to Pay (WTP) assessments for climate change mitigation options by households. There are many studies on WTP assessment for climate stability conducted in recent years. The paper surveys the existing literature on WTP for climate change mitigation policy in the energy sector. The aim of the paper is to identify the common variables across a varied set of WTP studies in order to establish a basis for comparison. The key variables selected for analysis of WTP studies for climate change mitigation in energy sector addressed in the paper are: the WTP assessment methods; the main attributes used for comparing alternatives in WTP studies, targeted climate change mitigation policies in energy sector, mathematical model used to estimate WTP, the main socio-demographic factors having impact on WTP for climate change mitigation policies. The analysis of WTP studies for climate change mitigation is grouped in two areas: renewables and energy efficiency measures in households. The paper provides analytical structure for future studies to evaluate the effects of variation in key comparative elements upon WTP. [ABSTRACT FROM AUTHOR]
