The study seeks to provide a varieties of policy options to a newly appointed Minister on best way to reduce greenhouse gas (GHG) emissions. The study is a policy brief submitted to examine policy options that can be considered by a Minister of Environment to solve the quagmires of GHG...

This paper addresses the trade-off between unfavourable air pollution levels and favourable weather conditions for selecting a date for the staging of an outdoor event. For an event date that has been fixed, it presents a personal preference-based data-driven decision framework for individual...

As an important step towards building a “harmonious society” through “scientific development”, China has incorporated for the first time in its five-year economic plan an energy input indicator as a constraint. While it achieved a quadrupling of its GDP while cutting its energy intensity...

Ground level ozone remains a serious problem in the United States. Because ozone non-attainment is a summer problem, episodic rather than continuous controls of ozone precursors are possible. We evaluate the costs and effectiveness of an episodic scheme that requires people to buy permits in...

This paper empirically examines the vehicle type regulation that was introduced under the Automobile Nitrogen Oxides-Particulate Matter Law to mitigate air pollution problems in Japanese metropolitan areas. The vehicle type regulation effectively sets various timings of vehicle retirement by the...

In most countries, environmental regulation focuses on local pollution, which causes damages near the emission source, while regulation on global pollutants such as greenhouse gases (GHG) has been slow. Theoretically, local and global pollutants can either be substitutes or complements in...

This paper endeavors to explain how wind speed can affect the diffusion of COVID-19. The statistical analysis, based on data from Italy, suggests that high wind speed can reduce air pollution commingled with viral agents and as a consequence reduce infected individuals of COVID-19; moreover,...

Just prior to the Copenhagen climate summit, China pledged to cut its carbon intensity by 40-45% by 2020 relative to its 2005 levels to help to reach an international climate change agreement at Copenhagen or beyond. This raises the issue of whether such a pledge is ambitious or just represents...
