To limit the global temperature rise to 1.5°C in 2100 compared to mid nineteenth century, net post 2015 emissions should amount maximum 200 Gigaton Carbon (GTC) or 734 GT CO2 emissions [Millar, 2017]. Annual world CO2 emission rate was 36.2GT, and CO2_eq (the combined impact of all emissions on global warming, translated to the equivalent impact of CO2 emissions) emission rate  was 49 GT in 2016, [Carbonatlas, 2017]. Currently only 685 GT CO2 emission quota is left, or 14 years of emitting at the current emission rate. Estimates vary widely: IPCC thinks we only have 485 GT CO2 emission quota left, while the most pessimistic estimates talk about only 200 GT CO2. With this in mind, the ambition of the Dutch Operational Energy Strategy [Schulten 2017] to reduce the dependency on fossil fuels (and hence CO2 emissions) by 20 % in 2030, is not sufficient to meet the objectives of the Treaty of Paris. We have to choose whether to keep this ambition, defining much stricter ambitions, or invest differently to keep global warming within acceptable limits. This paper discusses CO2 emissions and their distribution both over different sectors and geographical, worldwide. Next the paper discusses the options we have on short and medium term to reduce emissions, and their impact on emission reduction.

Abstract Background Global warming is the most serious problem we face today. Each country is expected to ensure international cooperation toward minimizing risk. To evaluate the countermeasures, many researchers have developed integrated assessment models (IAMs). Then, how can each country achieve its emission quota? This study proposes models that analyze the economic impact of global warming in a region based on the results obtained by the global model. By using these suggested models, we perform a comparative analysis on three policy cases: a different regulations case, a unified regulation case, and an output redistribution case. Results We analyzed Japan as one of the case studies and found that more developed areas should implement stricter regulations in all scenarios. In addition, the case of applying different regulations by area (in a region) is not always preferable to using unified regulations in the region. Alternatively, the output gap between the output redistribution case and the different regulations case is much higher than the gap between the unified regulation case and the different regulations case. In all scenarios, the present values of the output of the output redistribution case are also higher than the other cases. Conclusions The different regulations case and the unified regulation case are based on the model without capital transfer between areas, whereas the output redistribution case is based on the model with free capital transfer between areas. Although both models are extreme situations, the regions close to the without capital transfer situation possibly have an incentive to use the different regulations policy, depending on the emission target. The regions close to the situation with free capital transfer would probably prefer unified regulation.

Energy conservation or energy saving is one of the most important methods for reducing CO2 emissions, which is known to be associated with global warming. Although development of renewable energy sources such as solar or wind energy is necessary, we must first pay attention to the fact that enormous amounts of energy are consumed uselessly at present. Energy saving should therefore be one of the first problems to be tackled. It may not only bring reductions in CO2 emission, but also may lead to savings in expenditure on energy. This paper introduces some of the initiatives taking place in Japan aimed at energy conservation.

Well-known professor Johan Rockström at Stockholm University claims that we are in control of things, now that the Earth Sciences have proven the biological  limits of our existing civilisations. But we do not know or have not begun the necessary large global adjustments towards a sustainable Planet Earth. The failure of the UN COP framework is blatant stating the ends but not the means of reducing significantly CO2 emissions. All major countries plan for much more energy in coming decades treating renewable energy sources as merely compliment to fossil fuels,  not substitutes. To accomplish the Paris Accord objevties (COP 21), coal power should be phased out.

Emission of carbon dioxide (CO2), a greenhouse gas, from typical passenger vehicles in Thailand was investigated using a chassis dynamometer in the Automotive Emission Laboratory. The vehicle running method was controlled under the standard Bangkok driving cycle. CO2 emissions were measured at three different speeds for the following four vehicle types commonly used in Thailand: heavy duty diesel (HDD), light duty diesel (LDD), and light duty gasoline (LDG) vehicles and motorcycles (MC). HDD vehicles had the highest average CO2 emission rate, followed by LDD, LDG and MC at 1,198.8±93.1, 268.4±21.3, 166.1±27.7 and 42.5±6.1 g km-1, respectively; all values were significantly different (p < 0.05) from each other. The effect of different fuel types, including diesel, gasoline 91, gasohol 95, gasohol 91, liquid petroleum gas (LPG) and natural gas for vehicles (NGV), on the CO2 emission level was also compared. HDD vehicles had a higher rate of CO2 emission when using either NGV or diesel, while LDD vehicles emitted more CO2 with diesel than with NGV. For LDG vehicles, more CO2 was emitted with gasohol 91 than with gasohol E20, LPG or NGV. Finally, MC had a higher average CO2 emission rate with gasohol 95 than with gasoline 91 and gasohol 91 at any vehicle speed. The CO2 emission rates obtained in this study can be used as a basis to create a database that supports development of an efficient transportation management system and reduced vehicular emission of greenhouse gases in Thailand.

It is generally accepted in the scientific community that carbon dioxide (CO2) emissions, which lead to global warming, arise from using fossil fuels, namely coal, oil and gas, as energy sources. Consequently, alleviating the effects of global warming and climate change necessitates substantial reductions in the use of fossil fuel energy. This paper uses a financial market-based approach to investigate whether positive stock returns cause changes in CO2 emissions, or vice-versa, based on the Granger causality test to determine cause and effect, or leader and follower. If Granger causality can be determined in any direction, this will enable a clear directional statement regarding temporal predictability between stock returns and CO2 emissions. The empirical data include annual CO2 emissions from fuel combustion of the three main fossil energy sources, namely coal, oil and gas, based on 18 countries with sophisticated financial markets that are in the Morgan Stanley Capital International (MSCI) World Index from 1971 to 2017. The empirical results show clearly that all the statistically significant causality findings are unidirectional from the stock market returns to CO2 emissions from coal, oil and gas, but not the reverse. More importantly, the regression results suggest that when stock returns rise by 1%, CO2 emissions from coal combustion decrease by 9% among the countries that are included in MSCI World Index. Furthermore, when stock returns rise 1%, CO2 emissions from oil combustion increase by 2%, but stock returns have no significant effect on CO2 emissions from gas combustion.

China declared a long-term commitment at the United Nations General Assembly (UNGA) in 2020 to reduce CO2 emissions. This announcement has been described by Reuters as “the most important climate change commitment in years.” The allocation of China’s provincial CO2 emission quotas (hereafter referred to as quotas) is crucial for building a unified national carbon market, which is an important policy tool necessary to achieve carbon emissions reduction. In the present research, we used historical quota data of China’s carbon emission trading policy pilot areas from 2014 to 2017 to identify alternative features of corporate CO2 emissions and build a backpropagation neural network model (BP) to train the benchmark model. Later, we used the model to calculate the quotas for other regions, provided they implement the carbon emission trading policy. Finally, we added up the quotas to obtain the total national quota. Additionally, considering the perspective of carbon emission terminal, a new characteristic system of quota allocation was proposed in order to retrain BP including the following three aspects: enterprise production, household consumption, and regional environment. The results of the benchmark model and the new models were compared. This feature system not only builds a reasonable quota-related indicator framework but also perfectly matches China’s existing “bottom-up” total control quota approach. Compared with the previous literature, the present report proposes a quota allocation feature system closer to China’s policy and trains BP to obtain reasonable feature weights. The model is very important for the establishment of a unified national carbon emission trading market and the determination of regional quotas in China.

Abstract. Being the largest contributor to the global source of fossil-fuel CO2 emissions, China's emissions need to be accurately quantified and well understood. Previous studies have usually focused on the amount of national emissions and rarely discussed their spatiotemporal distributions, which are also crucial for both carbon flux and carbon management. In this study, we calculated China's CO2 emissions from fossil fuel use and industrial processes using provincial statistics and then mapped those emissions at 0.25° resolution on a monthly basis. Several key steps have been implemented to gain a better understanding of the spatiotemporal distributions, including (1) development and application of China's CO2 emission inventories using provincial statistics; (2) separate calculations of emissions from large point sources and accurate identification of their geographical locations; (3) development of 1 km × 1 km gridded population and GDP (gross domestic product) data for China from 2000 to 2009 and application of them as dynamic spatial proxies to allocate emissions; and (4) monthly variation curves of CO2 emissions from various sectors that were developed for each province and applied to our inventory. China's total CO2 emission from fossil fuels and industrial processes has increased from 3.6 billion tons in 2000 to 8.6 billion tons in 2009, which may be off by 14–18% and is enough to skew global totals. The resulting spatiotemporal distributions of our inventories also differed greatly in several ways from those derived using a national statistics and population-based approach for the various economic development levels, industrial and energy structures, and even large point emission sources within China and each province.

Environment issue is one of the most important problems which must be solved urgently. Today, the effects of climate change linked to global warming have started to come into view. Some gases such as methane (CH4) and carbon dioxide (CO2) which are called as greenhouse gases (GHGs) are seen as the most important causes of global warming. Harmful exhaust gases and CO2 emissions arise out of burning of fossil fuels on board. Maritime transportation is the most efficient mode when compared to other modes. However, Turkey's passenger and cargo transportation mainly depends on road transportation which has high fuel costs compared to sea transportation. In this study, by evaluating cabotage bunker fuels, annual CO2 emissions from maritime ships sailing on Turkish cabotage line were investigated. Also fuel efficiency of maritime transport as well as the effects of shifting cargo between transportation modes on CO2 emissions were analysed.

AbstractCarbon foot printing became an important term for surprisingly many people in the last years. It is very important that people learn what effects may have carbon foot printing on their lifes and how it’s produced. The term “carbon foot printing” is just a name which is the result of global warming potential. Carbon foot printing is considered a very popular buzzword in Romania in the last year. The carbon footprint measures total greenhouse gas emissions caused directly and indirectly, by a person, organization, event or product. In Romania the carbon emissions are the consequences of burning of fossil fuels and manufacturing of cement, and the value of CO2 emissions in 2008 was 94,660(kt). People can do training or courses to learn more about the meaning of carbon footprints, their impact on the environment and calculation of the carbon footprint by measuring the CO2 equivalent emissions.
