Accounting and finance are intricately intertwined with the global quest for environmental sustainability by applying accounting and finance tools for carbon reduction initiatives. Clean energy financial investment is one of the many alternative tools through which accounting contributes to carbon reduction. Accordingly, this paper analysed the impact of separate and integrated clean energy investment alternatives on carbon reduction. Data on clean energy financial investment and carbon emission per capita were collected from the International Energy Agency (IEA) and Our World in Data archives, respectively. Data was analysed by using multiple pooled OLS to evaluate the impact of individual clean energy financial investments on carbon reduction and the impact of integrating the various clean energy financial investment alternatives on carbon reduction separately. Findings show that individual clean energy financial investments may not separately offer desired carbon reduction, hence, albeit some negative coefficients, individual clean investments showed no significant impact on carbon reduction. However, furthering the test by pooling all the clean energy financial investment alternatives shows a significant negative effect of clean energy financial investment on carbon reduction at a P-value of 0.05. This shows that an integration of different alternatives of clean energy financial investment may offer an enhanced reduction of carbon emission, which outweighs the effect of relying on a single clean energy investment alternative. The findings offer significant insight for policy makers’ future strategies towards a combination of multiple clean energy financial investments. Furthermore, the findings from this paper are a further testament that accounting and finance are connected with the global quest for environmental sustainability through the application of accounting and financial investment tools in conducting clean energy financial investment.

In Indonesia, the government invites business actors to jointly reduce greenhouse gas emissions through disclosure of carbon emissions. Disclosure of carbon emissions in Indonesia is still voluntary (voluntary disclosure), so not all companies disclose this information in their reports. The purpose of this article is to assess the impact of factors such as company size, profitability, company growth, environmental committees, and gender diversity on carbon emission disclosure by Indonesia’s manufacturing companies. For the study, the authors selected 16 manufacturing companies listed on the Indonesia Stock Exchange in 2014-2018. The activities of these companies are the subject of study. To measure the extent of the carbon emission disclosure, a checklist is developed based on the measurement sheet provided by the Carbon Disclosure Project (CDP). The CDP is an organisation based in the United Kingdom which supports companies and cities to disclose the environmental impact of major corporations. The main idea of the project is that environmental reporting and risk management should become a business norm in order to ensure sustainable development of the economy. The study results show that company size has an effect on the level of carbon emission disclosure. The bigger is the company – the greater is the pressure that results from its economic activities. Therefore, the government and the public pay more attention to such business entities. It prompts the company to disclose its carbon emissions. At the same time, such factors as profitability, company growth, environmental committee and gender diversity do not affect on carbon emission disclosure. It was found that the level of carbon emission disclosure among Indonesia’s manufacturing companies is very low, and therefore the government and society need to take measures to increase the responsibility of business entities for environmental pollution.

Economic development has largely contributed to the increment of CO2 emission. This study uses spatial econometric models to investigate the relationship between economic growth and carbon emission in China with data of 30 provinces of China during the period of 2000 to 2012. Results show that the relationship between carbon emission and economic growth in China during the recent decade has the development tendency toward an inverse U-shaped curve, approximately confirming the carbon emission’s Kuznets curve hypothesis in China. There exists a significant spatial correlation between carbon emission and economic growth,implying that carbon emission in a province may be influenced by economic growth in adjacent provinces. When economic growth reaches 279.91 million Yuan/km2 GDP (at a comparable price in 2000), the contradiction between economic growth and carbon emission begins to be gradually alleviated. These findings provide new insights and valuable information for reducing carbon emissions in China.
