The synergic impacts of air pollution control policies on pollutants and carbon emissions.

The Chinese government implemented air pollution control policies in its Five-Year Plans (FYPs), setting specific emission reduction targets for different regions. This study employed the generalized difference-in-differences (GDD) method to assess the impacts of air pollution control policies on pollutants and carbon emissions from 2003 to 2020. This study had three main findings.

The synergistic impact of incentive and regulatory environmental policies on firms' environmental performance.

The imperative to enhance corporate environmental performance is not only pivotal for a company's growth but also crucial for fulfilling societal responsibilities and protecting global environmental interests. Recognizing the inadequacies of standalone environmental policies, our study delves into the synergistic effects of incentive-based and regulatory approaches on the environmental performance of listed firms in China. We meticulously examine the interplay between environmental punishment and subsidies over the period of 2015-2019.

Impacts of poverty eradication on carbon neutrality in China.

China is facing challenges to tackle the threat of climate change while reducing social inequality. Poverty eradication requires improvement in the living conditions of low-income households, which leads in turn to higher carbon footprints and may undermine the efforts of climate change mitigation. Previous studies have assessed the climate impacts of poverty eradication, but few have quantified how the additional carbon emissions of poverty eradication are shared at the subnational level in China and the impact on China's climate targets.

The global mismatch between equitable carbon dioxide removal liability and capacity.

Limiting climate change to 1.5°C and achieving net-zero emissions would entail substantial carbon dioxide removal (CDR) from the atmosphere by the mid-century, but how much CDR is needed at country level over time is unclear. The purpose of this paper is to provide a detailed description of when and how much CDR is required at country level in order to achieve 1.

The carbon border adjustment mechanism is inefficient in addressing carbon leakage and results in unfair welfare losses.

The European Commission has proposed a Carbon Border Adjustment Mechanism (CBAM) to reduce carbon leakage and create a level playing field for its domestic products and imported goods. Nevertheless, the effectiveness of the proposal remains unclear, especially when it triggers threats of retaliation from trading partners of the European Union. We apply a Computable General Equilibrium model - Global Trade Analysis Project - to assess the economic and environmental impacts of different CBAM schemes.

The Polarizing Trend of Regional CO Emissions in China and Its Implications.

CO emissions are unevenly distributed both globally and regionally within nation-states. Given China's entrance into the new stage of economic development, an updated study on the largest CO emitter's domestic emission distribution is needed for effective and coordinated global CO mitigation planning. We discovered that domestic CO emissions in China are increasingly polarized for the 2007-2017 period.

The impact of the COVID-19 pandemic on the behaviour of bike sharing users.

Globally most governments implemented a 'Working from Home' (home office) strategy to contain the spread of the coronavirus in 2020 in order to ensure public safety and minimize the transmission of the virus. Unsurprisingly studies have found that COVID-19 has had a detrimental impact on urban transportation systems; however, the number of shared bicycle riders is progressively growing compared to other modes of public transit. The aim of this study is to investigate the influence of COVID-19 on the usage of shared bicycle systems in order to identify passenger travel patterns and habits.

Population ageing and deaths attributable to ambient PM pollution: a global analysis of economic cost.

Background: The health impacts of ambient air pollution impose large costs on society. Although all people are exposed to air pollution, the older population (ie, those aged ≥60 years) tends to be disproportionally affected. As a result, there is growing concern about the health impacts of air pollution as many countries undergo rapid population ageing.

The unequal contribution to global energy consumption along the supply chain.

Reducing fossil fuel consumption is a top priority option for climate change mitigation, which requires collaborations of partners along the supply chain, such as energy suppliers, energy consumers and final consumers of goods and services. A comprehensive analysis of fossil fuel consumption is useful for policymakers to reduce demand but still absent. This study explores the national contribution to global energy consumption from different perspectives in the global supply chain and is designed to complement current energy reduction policies.

Global supply-chain effects of COVID-19 control measures.

Countries have sought to stop the spread of coronavirus disease 2019 (COVID-19) by severely restricting travel and in-person commercial activities. Here, we analyse the supply-chain effects of a set of idealized lockdown scenarios, using the latest global trade modelling framework. We find that supply-chain losses that are related to initial COVID-19 lockdowns are largely dependent on the number of countries imposing restrictions and that losses are more sensitive to the duration of a lockdown than its strictness.

The sharing economy promotes sustainable societies.

A simultaneous improvement in both ecological and economic efficiency is necessary to achieve the Sustainable Development Goals (SDGs). The new sharing economy has potential to promote the needed shifts in collective consumption behaviour, but better governance models are urgently required.
