Environmental economics is concerned with how economic activities of producers and consumers affect the environment, in which we live. The environment supports economic activities in many ways. Due to excessive use of environment, many environmental problems have emerged. These environmental problems can undermine the goals of development in various ways. The environmental issues and their implications are important for future development of the world. This paper highlights various aspects of linkages between economy and environment. It also attempts to explain how population growth and poverty are interlinked with environment.

People have recently started to show a particular interest for the link existing between economy and ecology, including the environmental protection. This way, a new domain, called ecologic economy or eco-economy, has sprung into existence, aiming at the ensuring of the puttinginto- practice of the decisions regarding productive and social capital, while taking into account the characteristics of the natural capital, by using an ecological, economic and social accounting, both on a short and on a long term.There is a significant interest for reaching a balance between the degree of environmental deterioration the level of economic development, and also for getting over the touchy elements of the link between economy and ecology so as to achieve a peaceful relation between humanity and environment, seen as a main goal for ensuring the continuity of the human race in the geosistema planetary space.

The paper considers the influence of economic development factors on the state of the environment. The subject of the research is the processes of improving the sustainable development (SD). A theoretical model for analysis of environmental and economic development was worked out based on the existing methods and a more comprehensive presentation of information on the parameters of SD. Possibilities of achieving the Environmental Kuznets Curve as the conditions for the SD improvement are determined. A minimum condition to guarantee the nonavailability of deterioration in the SD was determined to overcome the point of maximum pollution. This point describes emissions of pollutants, taking into account the accumulation effect of the pollution, which can be observed from the moment of exceeding of the assimilation potential of the environment. Proposed approaches were applied to the development analysis relative to the environmental component, the case of carbon dioxide (CO2) emissions...

The results of the empirical test also offer some findings. The continuous increase of the investment shares in treating the environmental pollution, to some extent, has some negative impact on the economic growth, but it's the inevitable price for implementing sustainable development. However, if we consider the effectiveness of the environment to the consumers, the increase of the investment in treating environmental pollution is favorable of the long-term economic development. In the future, we still need to strengthen the control of environmental pollution and increase the efficiency of treatment as well as try to reverse the serious situation of environmental deterioration fundamentally. The measuring results also show that the intervention of local government brings much resistance for the treatment of environmental pollution and the change of the sustainable development concept has to start from the transformation of the concept of political achievement of the local officials. Therefore, we need to intensify the assessment of indictors on the social environment in the future evaluation of social and economic development and give more weights to relevant indicators as well as change the administration inertia and governing ideas of local governments.

Introduction: Environmental pollution is the major facing by every country. Natural resources are depleting rapidly, creating scarcity problem for the next generation. A large number of population particularly poor segments of societies are suffering badly. On the one hand, every country is trying to increase economic growth to alleviate living standard of their people and on the other hand, environmental

Environmental degradation occurs is influenced by economic growth and the means of transportation that support it, besides that, the population size also affects the occurrence of environmental degradation. This study aims to determine the effect of economic growth, population growth and total of transportation on environmental degradation in short and long term. This research uses dynamic time series autoregressive distribution lag method. The results showed that the gross domestic product (GDP) variable had a significant positive effect in increasing CO2 gas emissions both in the short and long term. The variable amount of transportation has a positive and insignificant effect on the increase in CO2 gas emissions in the short term and has a negative effect in the long term. Meanwhile, population growth variable has a positive and significant effect in the short term and negative and significant in the long term.

Solution of environmental problems on global and regional levels urges creation of adequate approaches to study the development of the regional economy and its interaction with the natural environment. For this purpose a generalized input-output model is proposed, which includes: block of fixed assets dynamics; several kinds of linear and nonlinear production functions; algorithms for balanced forecasting of technological structures; nature block describing dynamics of the main environmental indicators (such as: air and water pollution, state of forests and soil, mineral and bio-resources etc.) with self- and artificial restoration, economic and anthropogenic influences taken into account. Nature-Economy Simulation SYstem (NESSY) is used as a basic software tool for building and investigating such models. Application of the system to modeling scenarios of environmental -economic development of Russia is described. The model was built for 13 economic sectors and 8 basic natural resou...
