| Summary/Abstract |
To date, more than 650 university presidents across the United States have become signatories of the American College and University Presidents’ Climate Commitment (ACUPCC). A central goal of being a signatory is for a campus to achieve carbon neutrality. This article suggests that bringing the practice of experiential learning to the college classroom is a mechanism to help students understand and become involved in campus carbon-neutrality efforts. More specifically, it discusses the practical realities of using an undergraduate environmental-policy course to create policy proposals for our campus’s 2020 carbon-neutrality goal. The findings support a growing body of literature that demonstrates the value of experiential learning by enabling students to move from theory to practice.

| Summary/Abstract |
Low-carbon technology innovation (LCTI) is key to achieving energy conservation and emission reduction. As the main body of carbon emissions, accelerating the promotion of energy enterprises' LCTI is urgently needed. Based on the importance of horizontal coopetition and government regulation for enterprises' LCTI, this paper establishes a tripartite evolutionary game model of local government and two homogeneous energy enterprises to clarify their dynamic behavior strategies. Furthermore, through numerical simulation, a sensitivity analysis of the effect of the main parameter changes on all parties' evolution is carried out. Moreover, we obtained the accurate optimal value of S&P (subsidies and penalties) by using a combination of random jumping and L-BFGS-B method. The findings indicate that (i) increasing the initial willingness of government and enterprises can facilitate faster system evolution towards optimal state. Early governmental intervention can be beneficial in preventing negative behavior of enterprises. (ii) There exists optimal range, and even optimal level, for government S&P, with penalties being more effective than subsidies in promoting LCTI. (iii)Low coopetition is ineffective while the intensity of coopetitive relationship is positively correlated with its’ effect. (iiii) Small-scale enterprises are more sensitive to changes in S&P measures and coopetition relationships.

| Summary/Abstract |
Despite similarities in their current energy mixes, France and Sweden's pathways have been very different since the 1970s, when both systems were highly dependent on fossil fuels. After the oil crisis, both countries chose to reduce their oil consumption by developing nuclear power. However, Sweden pursued a more diversified energy policy that has subsequently allowed it to reduce its CO2 emissions. Today, both countries have committed to a carbon neutrality goal: by 2045 for Sweden and 2050 for France. In order to understand the key factors that can drive energy transition toward a carbon neutrality goal, we propose to compare the past energy transitions in France and Sweden, two countries that have significantly reduced their CO2 emissions and fossil fuel dependency. To assess the impacts of the current energy system and its regulations on the feasibility of meeting carbon neutrality, we use TIMES bottom-up energy system optimization models. The results show that France faces more challenges in transforming its energy system than Sweden i.e. an increase in power production, a decrease in gas consumption, the replacement of heating systems in buildings, and the electrification of industry, thus confirming that its energy policy has to be driven with a long-run perspective.

| Summary/Abstract |
While the retirement of fossil fuel capacity is an inevitable consequence of the energy transition to carbon neutrality, policymakers face challenges in setting the pace in order that the energy transition policies do not significantly damage the economy. This paper designs a dynamic stochastic general equilibrium (DSGE) model to examine the macroeconomic effects of coal capacity cut policy (CCP) shocks on the Chinese economy. The results show that: firstly, an energy policy shock can distort the transmission effect of coal supply and demand and other factors on coal prices. Secondly, the impact of different policy tools is significantly different on the macroeconomic system, in which the economic effect of advanced capacity replacement is the weakest. Thirdly, in the short term, no matter which policy tool is adopted, the CCP will inevitably lead to a reduction in social welfare levels. The study suggests that in the short term, the Chinese government can further release more replacement quotas of capacity with advanced production efficiency, and innovate other policy tools for coal industrial structural optimization and synergistic effects with environmental regulation. In addition, the results highlight the need for market mechanisms to further accelerate the energy transition over the long run.

| Summary/Abstract |
Road transportation accounts for 56% of India's transportation sector's CO2 emissions. Reaching carbon neutrality before 2070 requires the deep decarbonization of this sector. This study assesses the potential of battery electric vehicles (BEV) and fuel-cell vehicles (FCV) as the least-cost pathway toward carbon neutrality. We estimate the future demand for passenger and freight services and evaluate the impact of EV policies using the Integrated Model of Energy, Environment, and Economy for Sustainable Development/Technology (IMED/TEC). The study covers road transport emissions, energy, and air pollution transitions under four scenarios, including reference, low, medium, and high penetration of BEV and FCV, which align with the decarbonization target agreed upon under India's national policy. Results show that the carbon neutrality target would be challenging with BEV alone in road passenger and freight transportation because it is less efficient. Combined penetration of BEV and FCV can reduce air pollutant emissions significantly. Operative implementation of FCV could diminish more than 96% of the total road transport CO2 emissions. The analytical framework also proposes local climate change policies towards a carbon neutrality strategy to escalate the share of BEV and FCV in the Indian road transport sector.

| Summary/Abstract |
This essay focuses on three broad sets of issues that may not slow China's GDP growth to under 3 percent a year, but they will almost certainly create major social and physical problems that will be difficult to deal with. The first is the demographic and education challenges featured by a rapidly aging population combined with a large share of the population being under-educated. The second is the environmental challenges China faces in achieving the state goal of carbon neutrality by 2060. The third challenge is low consumption and unprecedentedly high investment, a strategy that has driven China's high growth rates in the past decades but is no longer sustainable. These three challenges are intertwined, making China's adjustment path even more uncertain. What would a sustainable development strategy involve? The clearest need is to shift investment away from energy-intensive housing and infrastructure and toward investment in people.

| Summary/Abstract |
Most countries of the world have put forward the goal of striving for carbon neutrality. The goal is hard to achieve by only relying on supply side solutions for the world. Most countries should pay more attention to the potential of energy conservation and emission reduction in the field of final demand. We construct an empirical analytic framework to investigate energy demand characteristics as economic growth from the perspective of final demand, and the results show a U-shaped curve relationship between the ratio of energy embodied in consumption to energy embodied in investment (REECEEI) and real gross domestic product per capita. The REECEEIs of major developing and developed countries are very different. Compare to the average baseline curve scenario, there is a notable conservation potential of energy embodied in final demand for major developing and developed countries. In climate negotiation, the demand for energy embodied in investment of developing countries should be guaranteed because it is the foundation of their economic development. To conserve energy and reduce emissions in the field of final demand, developing countries should focus on the field of energy embodied in investment, while developed countries should focus on the field of energy embodied in consumption.
