During the past two decades, the world has seen exponential growth in the number of companies reporting environmental, social, and governance (ESG) data, and various ESG metrics have been proposed and are now in use. ESG metrics play a crucial role as an enabler of investment strategies that consider ESG factors, which are often referred to as “ESG investments”. The ESG metrics and investment market are evolving rapidly, as investors, corporations, and the public are giving more priority to the

Notwithstanding the global turn to renewable energy, its development is constrained by a lack of social acceptance. Various studies have evaluated citizens’ acceptance of and willingness to pay (WTP) for renewable energy and associated factors. We broadened the analytical framework of previous studies by incorporating spatial data on renewable and nonrenewable power plants, natural and produced capital, and renewable energy potential to determine key factors affecting social acceptance measured

This study combines regression analysis with machine learning analysis to study the merit order effect of renewable energy focusing on German market, the largest market in Europe with high renewable energy penetration. The results show that electricity from wind and solar sources reduced the spot market price by 9.64 €/MWh on average during the period from 2010 to 2017. Wind had a relatively stable impact across the day, ranging from 5.88 €/MWh to 8.04 €/MWh, while the solar energy impact varied

Still a lot of Indonesia's population lacks access to electricity, and a large number of those people live in remote areas or on islands. Traditionally, electrification of areas not yet connected to the main electricity grid and too remote for grid extension has mainly been achieved through installation of decentralized generation units with diesel generators. However, with decreased cost of renewable energy technologies, renewable hybrid mini-grid systems are becoming economically viable option

s PhD dissertation addresses one of the most important global issues of the twentyfirst century, i.e. how to end humanity's reliance on fossil fuels and make the transition to cleaner sources of energy.In particular, the energy transition in the developing countries is expected to be much more difficult than that in advanced ones because of the relative scarcity of financing, technology and trained human resources in the renewable energy (RE) sector.Promoting foreign direct investment (FDI) in t

The coronavirus (COVID-19) pandemic has affected society in immeasurable ways, including investment. As the pandemic has impacted society's values, it has proven to be a major turning point for environmental, social, and governance (ESG) investment. This investment approach, which evaluates a company's ESG ratings alongside traditional financial metrics, was already “coming off a banner year,” and its reach continues to expand. Although numerous studies have investigated the impact of ESG scores

Achieving carbon neutrality by 2050 requires the rapid adoption of innovative carbon removal technologies such as Direct Air Capture (DAC). However, the success of DAC deployment hinges not only on technological advancements but also on social acceptance. This study investigates the psychological and socio-economic determinants influencing public preferences for DAC-U (Direct Air Capture and Utilization) technology in Japan, utilizing a nationwide survey of 3139 respondents.
