Air quality is crucial for human health and welfare. A large number of studies have indicated strong

associations between ambient air pollution levels and adverse health effects. There is a considerable number

of literature reports concerning changes in atmospheric greenhouse emissions, while relatively little is known on

changes in atmospheric CO emissions. This paper presents the rate of changes in atmospheric CO emissions using the

logarithmic method in the assessment of this rate. Studies were conducted based on source data from 32 Organization

for Economic Cooperation and Development countries. Analyses covered the period of 2005–2012. It was found that

the average rate of changes had a negative average rate for most, although not all analyzed countries. In three of the

32 countries atmospheric CO emissions increased in that period. While the intensity of these changes varied, a defi nite

majority of the countries reduced their CO emissions, whereas Turkey, Poland and Estonia increased their emissions.

The main goal of the research is to develop a set of guidelines for the development of business within the framework of the green industry, in compliance with all current environmental regulations, as applied to the realities of the current economic situation in China. The methodology basis is a combination of system analysis of the key principles of business development within the framework of environmental strategy in China with a comprehensive analysis of green industry concept as a factor limiting the activities of enterprises to avoid environmental pollution. The results obtained in the research indicate the presence of significant results in the interaction of government and business in the framework of mutually beneficial collaboration for the growth of the green industry. Chinese business structures invest in the development of “green” industrial and manufacturing technologies while ensuring the necessary level of environmental protection.

The paper deals with recent developments in the fields of applied mathematics and operational research triggered by the needs of effective support of environmental policy-making processes that require interdisciplinary science-based advice. Mathematical models developed for this purpose demand new modeling paradigms for an adequate integration of pertinent knowledge. and creation of knowledge needed for rational decision-making. The article first summarizes the model-based support for problem solving from the point of view of actual decision-makers. Next, il discusses the model representation of the knowledge pertinent lo a given decision-making problem, and the recently developed modeling technology supporting the whole process of modeling complex problems. The last parł deals with novel methods and tools for integrated management of risks related to natural catastrophes. The presented methodology is illustrated by its application lo actual environmental policy-making support.
