In 1993, on-road emissions in Continental Europe showed a pronounced South/North declining gradient for CO, HC and NO fuel specific emissions (gm/kg). Emissions in Hamburg and Rotterdam were comparable to emissions measured in 1993 in the U.S.A. with the same on-road instrument. Contrasts between emissions in the USA, the UK and Sweden demonstrated the importance both of modern catalysts and of...

The prosperity of a country, commonly measured in terms of its annual per capita Gross Domestic Product (GDP), has different relationships with population levels of body weight and happiness, as well as environmental impacts such as carbon emissions. The aim of this study was to examine these relationships and to try to find a level of GDP, which provides for sustainable economic activity, opti...

China is the largest CO2 emitter in world, and it shared 28% of global emissions 2017. According to Paris Agreement, estimated that China’s will reach its peak by 2030.

This paper analyses empirically the dynamics of regional inequalities in GDP per capita. Our starting hypothesis is that the evolution of regional inequalities should follow an inverted u-shaped curve depending on the level of national economic development. This hypothesis relates directly to a number of theoretical findings put forward in the new growth literature, in particular, by Tamura (19...
