Road complex which includes a road network with traffic, road services, car repair businesses, and enterprises for the production of fuels and materials for the repair of roads, is an important source of environmental pollution, and the degree of contamination depends on the quality of the road pavement. The present research is aimed to find the interaction between the amount of emissions into the environment from whole road complex and condition of road cover, on creation of a simplified method of determining economic damage from environmental pollution at the road operation and to develop basic mechanism of the economic impact on road services at excess emissions. According to the results of computer experiments mathematical relations of complex road emissions from the evenness of road pavement were obtained. Worked out method of greenhouse (and other) emission inventory permits to determine the total amount of emissions and to identify excess emissions relative to some acceptable level. Definition of economic damage of environmental pollution during road operation can be the basis for determining the amount of ban impositions on road service.

This paper focuses on the catalytic properties of Ag/SnO₂ for low-temperature methane oxidation. The influences of the metal loading (0.2-20 wt.% Ag), support (Al₂O₃, TiO₂, SiO₂) and methane concentration (0.375-1.5%) in the oxidized mixture were investigated. It was observed that the optimal amount of silver in Ag/SnO₂ was 1 wt.%. Lower or higher amounts cause a loss in catalytic activity. SnO₂ was found to be undoubtedly the best support for the title reaction among all tested oxides. A mechanism of methane oxidation over Ag/SnO₂ was proposed.

The regional carbon budget of the climatic transition zone may be very sensitive to climate change and increasing atmospheric CO2 concentrations. This study simulated the carbon cycles under these changes using process-based ecosystem models. The Integrated Biosphere Simulator (IBIS), a Dynamic Global Vegetation Model (DGVM), was used to evaluate the impacts of climate change and CO2 fertilization on net primary production (NPP), net ecosystem production (NEP), and the vegetation structure of terrestrial ecosystems in Zhejiang province (area 101,800 km2, mainly covered by subtropical evergreen forest and warm-temperate evergreen broadleaf forest) which is located in the subtropical climate area of China. Two general circulation models (HADCM3 and CGCM3) representing four IPCC climate change scenarios (HC3AA, HC3GG, CGCM-sresa2, and CGCM-sresb1) were used as climate inputs for IBIS. Results show that simulated historical biomass and NPP are consistent with field and other modelled data, which makes the analysis of future carbon budget reliable. The results indicate that NPP over the entire Zhejiang province was about 55 Mt C yr-1 during the last half of the 21st century. An NPP increase of about 24 Mt C by the end of the 21st century was estimated with the combined effects of increasing CO2 and climate change. A slight NPP increase of about 5 Mt C was estimated under the climate change alone scenario. Forests in Zhejiang are currently acting as a carbon sink with an average NEP of about 2.5 Mt C yr–1. NEP will increase to about 5 Mt C yr–1 by the end of the 21st century with the increasing atmospheric CO2 concentration and climate change. However, climate change alone will reduce the forest carbon sequestration of Zhejiang’s forests. Future climate warming will substantially change the vegetation cover types; warm-temperate evergreen broadleaf forest will be gradually substituted by subtropical evergreen forest. An increasing CO2 concentration will have little contribution to vegetation changes. Simulated NPP shows geographic patterns consistent with temperature to a certain extent, and precipitation is not the limiting factor for forest NPP in the subtropical climate conditions. There is no close relationship between the spatial pattern of NEP and climate condition.

The nations need more and more energy to achieve their main objectives, launching the economic growth, or at least maintaining it. There is a relationship characterized by an inverted U-shaped curve between the emissions of pollutants (some local contaminants, such as nitrogen oxides, sulfur dioxide, heavy metals) per capita and GDP per capita distribution. We selected nine observation variables and twenty-seven observation units. Each observation units are OECD member states. It is expected to be confirmed that between the values of the energy consumption and greenhouse gas emissions and gross domestic product growth there is a statistically significant relationship. The so called developed countries need more and more energy to produce their GDP (for example agricultural production) and because of this their CO2 emission increased in the observed period of time. The strongest relationship of the whole analysis is between the observation units, energy consumption and CO2 emission. Unfortunately we can state that if a country wants to raise its GDP-level this country will use more energy to achieve this goal. The source of the large part of extra energy will be fossil fuels because they are still the cheapest energy sources.

Carbon dioxide (CO2), Methane (CH4) are two most potent greenhouse gases and are major source of climate change. Human activities particularly fossil fuels burning have caused considerable increase in atmospheric concentrations of greenhouse gases. CO2 contributes 60% of anthropogenic greenhouse effect whereas CH4 contributes 15%. Ice core records also show that the concentrations of Carbon dioxide and methane have increased substantially. The emission of these gases alters the Earth’s energy budget and are drivers of climate change. In the present study, atmospheric concentration of CO2 and CH4 over Pakistan is measured using Atmospheric Infrared Sounder (AIRS). Time series and time averaged maps are prepared to measure the concentrations of CO2 and CH4. The results show considerable increase in concentration of Carbon dioxide and methane. The substantial increase in these concentrations can affect human health, earth radiative balance and can damage crops.
