Climate change and global warming impacts are manifesting on a daily basis all over the world. Reports of catastrophic weather events are always being aired in the news, showing huge and massive destruction to property and life. Carbon emissions by both industrialised and non-industrialised countries are the main causes of global warming and climate change. While the developed nations are making frantic efforts through innovations and technologies to adapt to the changes in the climate, the developing countries do not have the capacity to develop such technologies, hence unable to adapt to the changes, leaving them with mitigation options. Against this backdrop, South African Government has put in place various interventions to curb the surge of global climate change. However, it is pertinent to point out that till date, there is no single law passed by the parliament specifically on global climate change. This notwithstanding, in view of the fact that global climate change is caused by emissions of harmful gases to the atmosphere and the environment, South Africa has ample laws controlling and regulating the environment. Therefore, the paper seeks to advance a compelling argument on implementation and enforcement of policy and law on carbon emissions reduction and how the law can be strengthened as part of mitigation strategy. As the issues surrounding global climate change relate and strictly pertain to the environment, the relevant environmental laws that are in place could be used to control and reduce emissions of all sorts and also enforce compliance. One of such pieces of legislation is the National Environmental Management: Air Quality Act 39 of 2004. DOI:10.5901/mjss.2014.v5n23p2709

The present paper addresses two policy objectives that the environmental regulator aims to accomplish: to implement a market for permits and make regulation acceptable for businesses. Profit-neutral permit allocations are defined as the number of permits that the regulator should give for free so that profits after regulation (i.e. profits that the firm realizes in the market for products plus the value of the allowances granted for free) are equal to profits before regulation. The paper demonstrates that a low number of free allowances is sufficient to meet these two goals. Moreover, even when the reduction is high, the regulator can fully offset losses if the concerned sectors are not in a monopoly context. The suggested model is developed by assuming that firms compete "à la Cournot", use polluting technologies and the demand function is iso-elastic. It is then illustrated by the first two phases of the EU Emissions Trading System.

"The book studies the relationship between economic agglomeration and environmental pollution from a spatial perspective through theoretical analyses and empirical discussions. At both microscopic and macroscopic levels, the author first explores the impact mechanism of the agglomeration of economic activities on environmental pollution and proposes research frameworks based on spatial economic theory and output density theory. Drawing on descriptive statistics and explorative spatial data from 283 cities in China, the book investigates the current development, spatial characteristics, influence path, and environmental efficiency of urban economic agglomeration and pollution in the People's Republic. The following empirical sections study spatial spillover effects, simultaneous bias and spatial interaction between agglomeration and pollution. The research findings give insight into interregional economic development, joint pollution control across regions, and the coordination of the two, especially in the context of developing countries. The title will appeal to researchers, students, government officials and policymakers interested in development economics, regional economics, urban economics, and environmental economics"--
