The objective of this paper is to establish whether the estimated relationship between environmental degradation and per capita income corroborates the inverted U-shape hypothesis as exemplified by the Environmental Kuznets curves (EKCs) in selected ECOWAS countries. Considering two variants of...

This paper estimates the linkages among total Sulphur dioxide (SO2) emissions, total GDP and energy efficiency using China's provincial panel data from 2002 to 2015. We investigate total emissions rather than per capita emissions or ambient concentrations, since it is total emissions that the...

In this paper, we examine the relationship between economic and environmental performance. More specifically, we analyse the impact of SO2 reduction in the eighties (1980-1992) on productivity growth, technical efficiency and technological progress for a set of 12 OECD countries. Our timeframe...

Environmental quality and climate change have long attracted attention in policy debates. Recently, air quality has emerged on the policy agenda. We calculate a new index of air quality using CO2 and SO2 emissions per capita as indicators and provide a ranking for 122 countries from 1985 to...

The hazardous waste sulfuric acid from alkylation process contains numerous organic pollutants and seriously threatens the ecological environment. Conventional pyrolysis process inevitably demands high investment and energy-extensive input, which constrains further large-scale applications....

4207 I examine the association between nighttime light luminosity and ten pollution measures (CO2, CO, NOx,SO2, NMVOC, NH3, BC, OC, PM10 and PM2.5) across different political regimes at a local level. Although the effects of the political system and economic growth on pollution have been widely...

Concerns for environmental quality and its impact on people's welfare are fundamental arguments for the adoption of environmental legislation in most countries. In this paper, we analyse the relationship between air quality and subjective well-being in Europe. We use a unique dataset that merges...
