<p>Surabaya is a metropolitan city in Indonesia. As well as the second largest city in Indonesia, with average yearly GDP growth of Surabaya increased 5 % of the national GDP, Surabaya has attraction for the urbanization and very strategic for the investors to build their industry in Surabaya. This leads to industrial sector, transportation, and the number of civilians growing rapidly which has the impact on the air quality in Surabaya. The most influential of air quality is the emission of Carbon Dioxide (CO2). Carbon Dioxide is a greenhouse gases that provide the largest contribution to global warming and climate change. This has negative impact to humans, so it is necessary conduct a research on the Carbon Dioxide emission growth being produced from the transportation, the industrial Sector, and household in Surabaya. The purpose of this research is to get prediction model for Carbon Dioxide emission growth being produced in the Surabaya. The prediction model can be represented the carbon Dioxide emissions growth in the next years that would give recommendations to the Surabaya Municipality Government for preventive action to reduce the Carbon Dioxide emission in Surabaya. </p><p><strong>Keywords</strong>: Carbon dioxide; emission; prediction <br /><br /></p>

Abstract Limiting emissions of harmful substances is a key task for vehicle manufacturers. Excessive emissions have a negative impact not only on the environment, but also on human life. A significant problem is the emission of nitrogen oxides as well as solid particles, in particular those up to a diameter of 2.5 microns. Carbon dioxide emissions are also a problem. Therefore, work is underway on the use of alternative fuels to power the vehicle engines. The importance of alternative fuels applies to spark ignition engines. The authors of the article have done simulation tests of the Renault K4M 1.6 16v traction engine for emissions for fuels with a volumetric concentration of bioethanol from 10 to 85 percent. The analysis was carried out for mixtures as substitute fuels – without doing any structural changes in the engine's crankshafts. Emission of carbon monoxide, carbon dioxide, hydrocarbons, oxygen at full throttle for selected rotational speeds as well as selected engine performance parameters such as maximum power, torque, hourly and unit fuel consumption were determined. On the basis of the simulation tests performed, the reasonableness of using the tested alternative fuels was determined on the example of the drive unit without affecting its constructions, in terms of e.g. issue. Maximum power, torque, and fuel consumption have also been examined and compared. Thus, the impact of alternative fuels will be determined not only in terms of emissions, but also in terms of impact on the parameters of the power unit.

Many studies that examine the impact of renewable energy installations on avoided carbon-dioxide utilize national, regional or state averages to determine the predicted carbon-dioxide offset. The approach of this computational study was to implement a dispatching strategy in order to determine precisely which electrical facilities would be avoided due to the installation of renewable energy technologies. This study focused on a single geographic location for renewable technology installation, San Antonio, Texas. The results indicate an important difference between calculating avoided carbon-dioxide when using simple average rates of carbon-dioxide emissions and a dispatching strategy that accounts for the specific electrical plants used to meet electrical demands. The avoided carbon-dioxide due to renewable energy technologies is overestimated when using national, regional and state averages. This occurs because these averages include the carbon-dioxide emission factors of electrical generating assets that are not likely to be displaced by the renewable technology installation. The study also provides a comparison of two specific renewable energy technologies: photovoltaics (PV) and wind turbines. The results suggest that investment in PV is more cost effective for the San Antonio location. While the results are only applicable to this location, the methodology is useful for evaluating renewable technologies at any location.

The Impact

Global environmental pressure dictates that South Africa reduces its greenhouse gas (GHG) emissions, while national objectives focus on economic development. South Africa is faced with the dilemma of simultaneously alleviating poverty, reducing unemployment, growing the economy and responding to international pressure to reduce GHG emissions. As a result, policies that promote energy emissions reduction without being harmful to economic growth and national developmental priorities are needed. Environmental fiscal reform presents one such option. The impact of this is still unclear for South Africa, and this paper explores this issue. Energy balance data on energy consumption, energy emissions and input-output data for South Africa are used to assess the economic and environmental effects of environmental reform in the energy sector. Despite the high reduction in energy emissions, a tax on coal is not selected as the best alternative given the high negative impact on the economy. A tax on oil results in a low reduction in energy emissions, which limits its use as an environmental policy. The scenario using a petroleum products tax results in small decreases in economic growth but it has low energy emissions reduction, hence, this alternative is not selected as an option. Energy subsidy reform offers the second highest reduction in real energy emissions and a low decrease in economic growth, and this scenario is therefore recognised as the best option for carbon dioxide reduction in South Africa. The electricity tax offers moderate reductions in real energy emissions and a moderate decrease in economic growth, and therefore, it is deduced that the electricity tax option could be another option for carbon dioxide emissions reduction in South Africa.

Dynamic Fluctuation

Currently, continuous China’s urbanization will emit considerable carbon dioxide emissions, so that China is facing mounting pressure from not only the international community but also domestic itself. This paper applies SVAR model to evaluate the dynamic fluctuation relationship between China’s urbanization and the disparity of urban-rural resident living direct carbon dioxide emissions. The result indicates that the urbanization has an obvious positive effect on the difference of resident living direct carbon dioxide emissions from urban and rural in the short term and it has negative impact in the long term. Moreover, the impact of urban-rural resident living direct carbon dioxide emissions disparity on the urbanization has a negative effect in the short term, gradually turns into a positive, and finally stabilizes zero level. Based on the above conclusions, the government should provide corresponding policy implications for China's carbon emission reduction.

In September 22, 2020, Xi Jinping said at the seventy-fifth general debate of the UN General Assembly that China will enhance the national independent contribution, and strive to achieve the peak of carbon dioxide emissions by 2030, and strive to achieve carbon neutralization by 2060. Under the goal of carbon peak and carbon neutralization, the implementation of carbon emission reduction is an important strategy for China to achieve green and low-carbon development, but also faces major challenges “The Fourteenth Five Year Plan” Period is an important window period for scientific and technological innovation to realize the transformation of carbon dioxide emission growth rate. Only with the support of scientific and technological innovation can China be expected to achieve the goal of carbon peak and carbon neutralization on schedule. This paper attempts to study how to innovate the energy undergraduate talent training mode under the goal of “carbon neutral” from the aspects of the current situation of talent training, the analysis of talent training objectives, and the path analysis of talent training mode innovation.

The Relationship

2019 was Earth's second warmest year since 1850. In 2019 the global mean temperature was cooler than in 2016, but warmer than any other year explicitly measured. Consequently, 2016 is still the warmest year in historical observation history. Year-to-year rankings are likely to reflect natural fluctuations in the short term, but the overall pattern remains consistent with a long-term global warming trend. This would be predicted from global warming caused by greenhouse gases, temperature increase across the globe is broadly spread, impacting almost all areas of land and oceans. Climate change" and "global warming" are often used interchangeably but are of distinct significance. Global warming is the long-term heating of the Earth's climate system observed since the pre-industrial period as a result of human activities, mainly the combustion of fossil fuel, which raises the heat-trapping greenhouse gas levels in the Earth's air. The term is often used interchangeably with the term climate change, as the latter applies to warming caused both humanly and naturally, and the impact it has on our planet. This is most generally calculated as the average increase in global surface temperature on Earth. Carbon dioxide emission is one of the main reasons for global warming. Since the Industrial Revolution, human sources of carbon dioxide emissions have been growing. Human activities such as the burning of oil, coal and gas, as well as deforestation are the primary cause of the increased carbon dioxide concentrations in the atmosphere. In our research, let’s examine the relationship between the amount of carbon dioxide emissions and the GDP/capita in developed and developing countries.

The objectives of this work were to evaluate the CO2 emission potential of an Oxisol under integrated crop-livestock and no-tillage systems in the Brasilian Savanna; and to analyze the impact of soil temperature and soil moisture as factors that regulate the seasonality and the emission of C-CO2 in these systems. Field-scale study was carried out at Fazenda Brejinho, in Pedro Afonso-TO, under Oxisol. The production systems studied were integrated crop-livestock and no-tillage under cropped with soybean and corn. The amount of carbon (C) released from the soil in the form of CO2 (C-CO2) was evaluated using cylindrical chambers installed in the field with a vial containing sodium hydroxide to collect CO2 released from the soil (soil emission) in an interval of 15 hours. Five evaluations were conducted over crops growing season, started in 01/26 through 06/16/2015. Data were tested to analysis of variance and the means were compared with Duncan test at 5%. The emission of C-CO2 differed between treatments in all evaluation periods. On average, the temperature ranged from 26.5 to 27.7 &deg;C, the soil moisture ranged from 12.2 to 15.7% and the C-CO2 emission ranged from 87.4 to 119.9 mg m-2 h-1. Temperature, soil moisture and the production systems contributed to the emission and seasonality of carbon dioxide emissions. The integrated crop-livestock cropped with soybean/corn rotation was the system that had the lowest carbon dioxide emission.

In this paper, we propose an integrated method, called quantile mediation analysis, which combines quantile regression and mediation analysis, to examine the impact of renewable energy on carbon dioxide emissions, whether connected to or separate from through economic growth, from 1990 to 2018 in Taiwan. The results of this novel approach indicate that Taiwan's renewable energy did not affect carbon dioxide emissions through the mediation effect of economic growth from the period of 1990 to 2018, and that there is only a direct effect from renewable energy to carbon dioxide emissions at any distribution. Moreover, this result is remarkably different from the result of the traditional ordinary least square approach, which shows that Taiwan‘s renewable energy affects carbon dioxide emissions through the partial mediation effect of economic growth. In conclusion, we suggest that the Taiwanese government should increase the use of renewable energy in reducing local and global carbon dioxide emissions.

Climate change is a phenomenon of environmental damage due to the increased intensity of carbon dioxide emissions in the atmosphere, which causes the surface temperature of the earth. The carbon dioxide emission is a form of environmental degradation caused by economic activities. This study analyzed the relationship of macroeconomic variables and the carbon dioxide emission in each of the four ASEAN countries (Indonesia, Malaysia, the Philippines, and Thailand). The used of macroeconomic variables (GDP, trade openness, energy consumption, and the exchange rate) is shown to explain the carbon dioxide emission. In this study, Vector Auto regression Exogenous (VARX) method is used to analyze the impact of economic activities on the movement of carbon dioxide emissions. The data used time series with a vulnerable time of the year 1981-2013. The estimation results from these studies show that the GDP variable has the greatest contribution to the dynamics of carbon dioxide emissions in each ASEAN 4 countries. This empirical finding suggests that economic activity has an influence on the growth of carbon dioxide emissions.

The Impact

In January 2008 the Governor of Hawaii announced the Hawaii Clean Energy Initiative; an initiative that aims to have at least 70 percent of Hawaii’s power come from clean energy by 2030 [4]. In July 2009, the Hawaii Department of Accounting and General Services awarded NORESCO, an energy service company, a $33.9M contract to improve the energy efficiency of 10 government buildings. The avoided utility cost of the energy and water savings from the improvements is the project funding mechanism. The energy savings realized by the project will reduce carbon dioxide emissions associated with utility power generation. However, as renewable energy becomes a larger portion of the utility generation profile through the Hawaii Clean Energy Initiative, the carbon dioxide emissions reductions from specific energy efficiency measures may erode over time. This work presents a method of analysis to quantify the carbon dioxide emissions reduction over the life of a project generated by energy efficiency upgrades that accounts for both the impact of policy initiatives and climate change using DOE-2/eQUEST. The analysis is based on the fact that HVAC energy usage will vary with climate changes and that carbon dioxide emission reductions will vary with both energy savings and the corresponding utility’s power generation portfolio. The energy savings related to HVAC system energy efficiency improvements are calculated over the life of a 20 year performance contract using a calibrated DOE-2/eQUEST model of an existing building that utilizes weather data adjusted to match the predictions of the Intergovernmental Panel on Climate Change. The carbon dioxide emissions reductions are calculated using the energy savings results and a projection of the implementation of the Hawaii Clean Energy Initiative. The emissions reductions are compared with other analysis methods and discussed to establish more refined expectations of the impact of energy efficiency projects in context with climate changes and policy initiatives.
