Nowadays, apart from travel time and cost, more and more attention is paid to ensuring that ecological footprint of the means of transport used for a journey is as small as possible. Therefore, it is reasonable to look for methods and solutions that will allow planning communication connections according to the principles of sustainable development. The aim of the article was to present mathematical model of the proecological distribution of traffic flow into a network, together with a determination of how the amount of emissions of harmful compounds for rail transport will be calculated (based on amount of energy necessary for movement, calculated on circumference of the wheels). The model has been verified on real data. The traffic flow was distributed over a selected communication route: Warszawa—Gdansk, where the criterion was minimization of total carbon dioxide emissions. An evolutionary method implemented in Microsoft Excel was used to solve the optimization problem. For the analysis of only the fastest connections, the railway one was the optimal from the point of view of the adopted criteria. After the train capacity was exceeded, air and car connections were loaded. Based on the research, a function that represents the amount of carbon dioxide emissions in the analyzed traffic route depending on the size of the traffic flow was developed.

By using carbon dioxide emissions in Taiwan, this study attempts to account for total carbon dioxide emissions and per capita emissions at city and county level, based on the household consumption structure in each region. Carbon dioxide emissions are translated into carbon footprint by using the ecological footprint (EF) method, followed by calculation of total and per capita carbon footprint for each city and county. Analysis results indicate that Taiwan's total carbon dioxide emissions in 2011 were 264.66 million tons, of which New Taipei City, Taipei City and Kaohsiung City were the highest. However, according to the EF framework, the per capita carbon footprint for Taiwan was 5.94 global hectares (gha) in 2011. The highest three counties and cities were Taipei City, Hsinchu City and Hsinchu County. Future research should incorporate the use of direct measures of carbon dioxide emissions in counties and cities, which would produce a more realistic outcome. Moreover, the feasibility of using the EF method to translate carbon dioxide emissions into carbon footprint should also be examined.

Per Capita

Take for example the BRIC economies: Brazil, Russia, India and China. We investigated the time series data on the relationship between carbon dioxide emission and economic growth in these fast-growing developing countries by both comparative statics and comparative dynamics. The results show that there is the monotonic relationship between total carbon dioxide emissions, carbon dioxide emissions per capita and per capita GDP in any one of the BRIC countries. And there is decreasing relationship between the carbon dioxide emissions per unit GDP and per capita GDP.

Kingdom Of Saudi Arabia

Because of increased demand for electrical energy in the Kingdom of Saudi Arabia, which has resulted in an increase in carbon dioxide emissions, the electricity system in the Kingdom of Saudi Arabia is the largest in the Gulf region and the Arab world, with approximately 61.7 gigatons (GW) of peak demand and 89.2 gigatons (GW) of available capacity in 2018 of electricity power. It has grown rapidly over more than 20 years and has almost doubled in size since 2000. Where we observe that the total carbon dioxide emissions in the Kingdom of Saudi Arabia from 1990 to 2020; where shows rapid growth in emissions of carbon dioxide and greenhouse gases, as it was found that CO2 emissions in 1990 amounted to 151 million metric tons compared to 2011 when it reached about 435 million metric tons, and the increase continued until 2020 when it reached about 530 million metric tons. The comprehensive study relied on time series analysis to carefully analyze the electric energy productivity rate from fossil fuels and the significant amount of carbon dioxide emissions typically resulting from promptly burning fossil fuels to naturally produce electric energy. Therefore, the Kingdom of Saudi Arabia, through Vision 2030 and the Paris Agreement on Climate Change, looks to reduce the rate of carbon dioxide emissions in the field of electric power generation by diversifying the fuels used or replacing them with clean and renewable energy such as solar and wind energy.

Reduce Carbon Dioxide

The Paris Agreement, adopted in December of 2015 at the 21st session of the UNFCCC Conference of the Parties and effected from November of 2016, coordinates the efforts of states to reduce greenhouse gas (GHG) emissions, including carbon dioxide. One of its largest emitters to the atmosphere is the metallurgical industry. Among the proposed ways to reduce carbon dioxide emissions is the widespread use of hydrogen in the ferrous metallurgy. An overview of the problems that the ferrous metallurgy will face when replacing carbon-containing fuels with hydrogen is presented. It was noted that the use of hydrogen in the ferrous metallurgy contains such technological risks as high cost in comparison with currently used fuels and reducing agents; explosion hazard and corrosion activity, the need for a radical reconstruction of thermal units when using hydrogen instead of traditional for the ferrous metallurgy natural, coke and blast furnace gases, as well as solid fuels. It is shown that minimizing these risks is not always possible or economically feasible, and the result of using hydrogen in the ferrous metallurgy instead of carbon-containing fuel from the point of view of reducing greenhouse gas emissions may be low with a significant increase of economic and social risks.

Simple Method

For those clinical laboratories equipped with a microprocessor-controlled gas analyser, an extremely simple method is described for the determination of the total carbon dioxide content in various biological fluids. Since this method needs only 20 μL of blood plasma or is less dependent on the original total carbon dioxide content, it is especially suited for paediatric purposes. With our procedure the time necessary for one determination equals the time for one capillary blood gas analysis.
