Summary: Policy makers need to consider global household inequality when setting optimal carbon instrument values. Poor households are more likely to support strong public action against climate change, while rich households prefer lower carbon prices.

Summary: The social cost estimates for methane and nitrous oxide have not kept pace with the latest scientific findings, but our study suggests that policies to mitigate these greenhouse gases would bring greater benefits and calls for a re-evaluation of their social costs.

Summary: This study explores the relationship between CSR and COC, and how mandatory CSR legislation influences this relationship. The findings suggest that higher CSR performance leads to lower debt costs and higher equity costs, while mandatory CSR legislation increases both debt and equity costs. This indicates that mandatory CSR spending signals a loss of discretionary power and an increase in agency costs.

Summary: The New Zealand Emission Trading Scheme (NZ ETS) is unique in its inclusion of forestry as a carbon sink. The scheme has undergone multiple policy changes, including a shift from unlimited importation of units to complete self-reliance. Through empirical analysis, we found that international offsets had a negative impact on NZU returns before the de-link date, while domestic supply affected returns after the official de-link date. Surprisingly, green offsets, mainly from forestry, had a positive effect on NZU returns before the de-link date. Demand-side factors, such as sectoral effects, also played a significant role in NZU returns.

Summary: A consistent estimation of the social cost of methane (SCM) is proposed using an extended DICE-2016R2 model that includes methane emissions, abatement cost, and atmospheric methane cycle. The estimated SCM in 2020 ranges from 880-8100 USD/tCH(4), with a base case estimate of 4000 USD/tCH(4). The SCM is found to be less sensitive to variations in the social discount rate compared to the social cost of carbon (SCC) due to the shorter lifetime of methane. The ratio of SCM to SCC is evaluated as an alternative metric to facilitate tradeoffs between methane and carbon gases.

Summary: The Java-Bali power system in Indonesia, which has the largest power capacity, contributes to significant CO2 emissions. To address this issue, the Indonesian government has introduced policies such as setting new and renewable energy targets and planning for coal phase-out, aiming to reduce CO2 emissions. This research examines the economic impacts on the energy and carbon nexus in the Java-Bali system, analyzing different scenarios of emission reduction using the OSeMOSYS model. The results highlight the importance of implementing policies that regulate carbon limits and taxes for power generation companies, as well as the significance of nuclear energy and liquefied natural gas in supporting the new and renewable energy targets and coal phase-out plan. Interconnection with other islands rich in renewable energy sources is also crucial for meeting the renewable energy targets and successfully implementing the coal phase-out plan.

Summary: Insufficient consideration of provincial heterogeneity and connection in energy consumption has led to inefficient and ineffective one-size-fits-all energy policies in China. This article developed an integrated prediction model to systematically investigate the spatial-temporal evolution trend of China's provincial-level energy consumption. The results indicate the need for more targeted energy policies, the importance of improving energy efficiency in certain provinces, and the inappropriateness of blind coal removal policy.

Summary: Carbon capture and storage (CCS) technology is an important option for reducing greenhouse gas emissions, particularly in the industrial sector. Utilizing the EPPA model, industrial CCS deployment is found to facilitate emission reductions and enable significant decreases in global energy use and sectoral emissions.

Summary: This study fills the gaps in previous research by evaluating the impact of fiscal policy and environmental policy stringency on consumption-based carbon emissions, specifically within the context of the BRICS countries. Utilizing data from 1990 to 2019, the study incorporates factors such as disintegrated energy and economic growth to analyze their influence on carbon emissions. The results indicate that economic growth, nonrenewable energy, and government expenditure intensify carbon emissions, while taxation revenue, environmental policy stringency, and renewable energy mitigate them. Furthermore, panel causality tests demonstrate the predictive power of taxation revenue, government expenditure, environmental policy stringency, and renewable energy on carbon emissions, leading to policy recommendations based on these findings.

Summary: Despite constitutional protection, caste-based discrimination in India has prevented millions of residents from accessing basic rights such as adequate food, quality education, employment based on merit, and basic living conditions. This paper examines the role of marginality in determining access to social capital for meeting basic needs in old age, and addresses issues related to living arrangements and financial security among the elderly population.

Summary: In this study, the effect of low-carbon city policy on carbon lock-in in Chinese cities is critically analyzed using a balanced panel dataset of 283 Chinese prefectural cities between 2003 and 2017, as well as the difference-in-differences method. Several key findings are highlighted: (1) Low-carbon city policy successfully inhibits carbon lock-in. (2) The dynamic effect of low-carbon city policy becomes more prominent over time. (3) The impact of low-carbon city policy on carbon lock-in differs across regions and is more effective in cities with strong government administrative power, industry structure upgrading, and technology innovation. (4) Low-carbon city policy indirectly affects carbon lock-in through environmental regulation, informatization, and human capital effects. Several specific policy implications are proposed to overcome reinforced carbon lock-in.

Summary: Despite increasing urgency to address climate change, new coal mines have been approved in countries like Australia, exacerbating the already high per capita CO2 emissions. The essential economic role of the coal industry in Australia gives it structural power to influence political dynamics.

Summary: This study analyzes emission trajectories and SCC under a carbon-neutral pathway, finding a peak warming of about 2.1 degrees C and highlighting that even if all countries meet their commitments, global warming cannot be limited to 1.5 degrees C. Climate change damages will primarily affect warmer and poorer countries, and current carbon taxes and trading prices are significantly lower than SCCs, indicating the need for further research and mechanism refinement.

Summary: We analyze the green investments in the Italian National Recovery and Resilience Plan (NRRP) by comparing environmental benefits and investment costs. Future discounted environmental benefits, in terms of expected greenhouse gas emission reductions, are computed using different estimates of the Social Cost of Carbon. Our findings indicate that some projects would not yield positive net present value unless the discount rate is low and benefits for developing countries receive greater weight. However, investments in renewable energy surpass the cost in a short period.
