Abstract
This paper examines the relationship between environmental performance, legislation and annual report disclosure using the case of Falconbridge and sulphur dioxide emissions over a period from 1964 to 1991. Legitimacy theory and political economy theory are used to evaluate the disclosure. Two key questions are addressed: How did the corporation respond to changing government regulations for sulphur dioxide abatement? and How did the corporation choose to present these abatement activities in its annual reports? These questions are examined through the methodologies of historiography, interviews and content analysis. Falconbridge has always been in compliance with SO2 regulations (albeit with a government extension in the late 1970s) and has consistently provided disclosure discussing the technological aspects of sulphur dioxide abatement. While political economy theory has explanatory power, legitimacy theory offers a more compelling explanation.

Abstract
The phenomenon of corrosion is so extensive that it is universally accepted as an inherent part of our present‐day commercial and industrial life. It is not surprising, therefore, to find corrosion problems associated with the most important of our chemical processes, the combustion of fuels. All our industrial fuels contain inorganic constituents, and during the combustion process certain of the more volatile constituents may be released in an active form to contaminate the combustion products.

Abstract
Purpose
Cement industry for both developed and developing countries is important from the economic point of view. It is playing a vital role in economic development of a developing country like Pakistan. However, these industries are posing threat to the environment, human health and plant species. The purpose of this paper is to identify the most critical factors of cement industry that have a negative impact on the environment, human health and plant species in the context of Pakistan.
Design/methodology/approach
The factors are categorized into air pollution, noise pollution, soil pollution, human health and plant species. These factors are categorized on the basis of previous literature and environmental safety reports. Air pollution is caused by iron and sulphur while noise pollution is mainly caused by crusher room and rotatory kiln end. The soil is being polluted by zinc and lead while human health and plant species are being damaged by sulphur dioxide and nitrogen dioxide. For the analysis purpose, a multi-criteria decision-making (MCDM) technique, i.e., decision-making trial and evaluation laboratory (DEMATEL) is used.
Findings
The result shows that the major cause of air pollution is “sulphur” while “crusher room and rotatory kiln end” are responsible for noise pollution. On the other hand, “mercury” is responsible for causing soil pollution while human health and plant species are influenced by the toxic effect of “nitrogen dioxide.”
Research limitations/implications
The results obtained are specific to cement manufacturing industry of Pakistan and cannot be generalized for any other manufacturing sector.
Practical implications
The proposed methodology shows the most critical factors toward which concertation should be given for mitigating their impact. This study will help the government and the cement industry to focus on all those elements that are the most responsible for causing different types of pollution.
Originality/value
No such work is reported in previous research that proposes a framework using DEMATEL technique for analysis of critical factors of cement industries that have a dangerous impact on the environment and human health, especially in a developing country, like Pakistan.

Abstract
In this Chapter, cerium (III) oxide nanoparticles were prepared by co-precipitation method using hydrogen peroxide as the precipitant in slightly alkaline medium which is greener and environmentally suitable, cheap and best as compared to other conventional methods. Here, hydrogen peroxide acts as precipitating, reducing and stabilizing agents. Since studies worldwide reveal a very strong, significant positive association between air pollution and COVID-19 cases, hence, this environment-friendly synthesis process will prove to be most economically effective one to combat the COVID situation. The synthesized cerium (III) oxide nanoparticles were initially noted through visual color change from colorless pale yellow cerium (III) to light yellow cerium (IV). Moreover, the formation and size of cerium (III) oxide nanoparticles were evidenced by the X-ray diffraction, transmission electron microscopy and UV-VIS spectroscopy studies. The very high surface area and very small average crystallite sizes of these prepared cerium (III) oxide nanoparticles (5–20) nm in size is mainly responsible for their catalytic properties and hence can be effectively used for the removal of hazardous toxic pollutant gases such as carbon dioxide and sulfur dioxide from the environment with a view to combat the pollution within the environment to increase sustainability and also ensure a better, healthy and safe environment, particularly, in context of COVID in globalized world. This chapter, as its main objective, mainly focuses on utility of the nanotechnology and its beneficiary in creating a sustainable environment in economic world, particularly for gender development. Since the gas sensors will detect and reduce gaseous toxic pollutants from the environment, so lower the pollution greater will be sustainable environment development in terms of human development index and hence higher will be overall economic development in favor of Gender Development Index across world. However, as major findings, developing countries have been successful in maintaining a sustainable human development, in spite of higher Per Capita Income (PCI) growth, as compared to the role of least developing countries, with lower PCI in this global world, in favor of their respective gender development.

Abstract
The Report of the Food Investigation Board (the Department of Scientific and Industrial Research) for the year 1934 is, as were its predecessors, a document of first‐rate interest and importance. The Board was established in 1917, and under its terms of reference it has “ to submit an annual programme of research and an annual report.” The revised terms of reference clearly indicate the wide interests, both scientific and industrial, with which the Board is concerned. Its duties are “ to advise generally on the conduct of research on the properties and behaviour of foodstuffs on the scientific problems, including physical and engineering problems, involved in their storage and transport.” The duties of the Board are obviously as far reaching as they could well be. By no means the least interesting feature of these reports taken as a whole is the close connection they show to exist between the laboratory and the market place. This fact alone—which emerges quite naturally as the work which has been done, or is being done, or that which it is proposed to do, is described — gives to these reports a claim on public interest which is almost unique in the annals of Government publications. The people of this country are, whether they generally realise it or not, more affected in their daily life by problems connected with the transport and preservation of foodstuffs than those of any other country. We are far from being self‐supporting. Half the meat we eat comes from overseas. Argentina supplies us with a very large proportion of our chilled beef. Australia and New Zealand have plenty of cattle that would furnish us with good beef, but the difficulty has been to ship it in a chilled as distinct from a frozen state to these shores, On the 18th July, 1933, a first consignment of chilled beef from New Zealand reached the London market. This beef had been stowed on board in an atmosphere containing 10 per cent. of carbon dioxide. It arrived in good condition. This preliminary consignment of chilled beef from the antipodes is very rightly referred to by the Board as “ an event which may well prove historic.” In 1934 four thousand four hundred tons of meat in gas (CO2) storage were sent from Australia and from New Zealand to this country. Thus a new and important chapter in Imperial economic relations has been opened, not inferior in importance to the original introduction of cold transport and of cold storage some fifty years ago. “ Given careful handling the use of gas storage eliminates mould and bacterial slime.” Slime is a thick growth of organisms of the Achromobacter group. It appears more quickly on meat which has a high initial bacterial count at the time of shipment, and the truth of this statement is borne out by the figures given in the Report. Achromobacter growth is inhibited at 0° C in the presence of carbon dioxide ; while Proteus and aerobacter are not thus inhibited, but their optima is 37° C. So that a low temperature and at atmosphere containing 10 per cent. of carbon dioxide suffices to eliminate these troublesome groups of micro organisms from meat during transport. The term “ careful handling ” may perhaps be extended to include good sanitary conditions in the slaughter houses. The Report for 1932 dwells on the need for a plentiful supply of hot water. The older method somewhat neglected this essential, and one bucket of water sufficed for several carcases. A bacterial count of the bacterial content of water which had been used for this purpose showed that with an insufficient supply of water the number of organisms per cubic centimetre varied from two to twenty‐five millions, with five thousand B. coli per ten cubic centimetres. With an abundant supply of water the corresponding figures were fifteen thousand and five ! As the life of meat in store depends on its freedom from bacteria the need for extreme cleanliness in the treatment of meat before it leaves the slaughter house need not be insisted on. The matter has of course received adequate attention in Australia and in New Zealand where beef is being prepared for shipment under the new conditions. Other problems still remain to be considered such as the best methods of stowage to prevent chafing ; degree of humidity in the hold during transport ; air circulation to ensure uniformity in the atmosphere of the hold ; and the maintenance of the correct temperature. If these conditions are complied with the “ bloom,” that is, the natural appearance of the meat, is retained. Otherwise the oxidation of hæmoglobin to methæmoglobin ensues and the “ bloom ” of the meat is lost. “ Bloom,” it is stated, does not affect the nutritive value of the meat, but the absence of “ bloom ” would presumably affect the price of the meat on the wholesale market as it ceases to be a factor when the meat has been cut up into joints. The successful transport of a cargo of chilled beef from Australia and New Zealand therefore depends on its being landed not only in a wholesome condition, but also in a condition that will enable it to compete on at least equal terms with its foreign competitors. This evidently implies the close and effective co‐operation of everybody concerned from the stockbreeder in Australia or in New Zealand to the retailer in London.

Abstract
The Brundtland Report (WCED, 1987) encouraged the view that the main threats to the environmental sustainability of development are poverty‐driven depletion of environmental resources in the developing world, and consumption‐driven pollution of the biosphere by the developed world. Recent work on the empirical relationship between per capita GDP growth and certain indicators of environmental quality seems to contradict this view. Some indicators of local air and water quality first worsen and then improve as per capita incomes rise. This paper reconsiders both these findings, and the empirical relation between environmental quality and measures of poverty, consumption and human development. It finds that deepening poverty at one end of the scale and increasing affluence at the other both have implications for the environment. But these implications are different. Deepening poverty is associated with environmental effects that tend to have immediate and local implications for the health and welfare of the communities concerned. Increasing affluence is associated with environmental effects which are much more widespread and much longer‐lasting. The environmental consequences of growth increasingly tend to be displaced on to others – either geographically distant members of the present generation or members of future generations. The paper argues that the relevant question is not whether economic growth has environmental consequences: it is whether those consequences threaten the resilience of the ecological systems on which economic activities depend. Since loss of ecological resilience implies that the economic activities concerned are environmentally unsustainable, it should be a major focus of strategies for sustainable development.
