Reducing Co2 Emission

Input-output model on cement plants were established. Carbon dioxide emissions of key steps and carbon footprint of products were calculated and predicted using the input-output model. The results showed that CO2 emission in the plant (the production of the plant is 1320000t a year) reached 910000 t a year and CO2 emission per ton product is 0.689 ton. Over 80% of the total CO2 was emitted during the process of firing，so the firing process is the key step for reducing CO2 emission in the cement plant. Carbon footprint of three kinds of cement products including ordinary portland cement, portland pozzolan cement and portland blast furnace slag cement are 0.76, 0.59, 0.72 respectively.

Abstract. The electricity consumption for commercial, residential, and industrial sectors is considered the primary cause of increasing carbon dioxide emissions. To calculate the carbon footprint, the researcher used Carbon Footprint Ltd. This study aims to quantify the carbon footprint associated with the consumption of electricity by sectors (residential, commercial, industrial, public buildings, and streetlights) in Butuan City during the pre-lockdown period (January and February), and then compare these with the carbon footprint calculated during the lockdown period (March and April 2020). A GIS-based approach was applied to generate the spatial distribution across the 86 barangays of Butuan City. The study findings that the carbon footprint in the lockdown period is ∼ −17% lower than the mean carbon footprint calculated for the pre-lockdown period. In absolute values, the total estimated carbon footprint during the pre-lockdown and lockdown period was ∼ 10,947 mtCo2e and ∼ 9,138 mtCo2e, respectively. Furthermore, the findings imply that the central and northern areas have the highest impact of savings on average ∼ 130 mtCo2e of greenhouse gas avoided by barangays. This research provides quantitative insight to understand the measured generated in lockdown and pre-lockdown periods.

This article explores the issues of carbon dioxide (CO2) emissions resulting from the production of the goods and services provided to supply tourism consumption. First, we define the scope of tourism activities and the resulting tourism consumption and tourism direct gross value added (TDGVA). Second, we calculate CO2 emissions for sectors and compile a carbon input-output table (CIOT). Third, we adjust the tourism-related products consumed according to the range of the corresponding sectors of the CIOT. Finally, we use Shanghai as an example to calculate the carbon emissions that result from tourism consumption using the input-output model. This study shows that the TDGVA accounted for 7.97% of the Gross Domestic Product (GDP) in 2012, whereas the carbon footprint of tourism accounted for 20.45% of total carbon emissions. The results demonstrate that tourism is not a low-carbon industry in Shanghai.

National Academy For Learning (NAFL), Bengaluru has been actively working to make the school carbon-neutral under the NAFL Green initiative. The present investigation conform the effort and presents the trajectory for understanding and estimating the carbon footprint of the school, and suggests potential solutions. It uses the GHG Protocol’s Corporate Standard, which categorizes emissions into three scopes based on their source. The study extensively explores each of the three scopes and emission offsets, and reports the carbon footprint of NAFL to be 107030kg CO2e. The major contributor to this is the third-party transportation facility, accounting for almost 75% of the emissions. The trees maintained by the school offset only 1.3% of the carbon dioxide emissions. This indicates that there still remains a huge scope for improvement in the carbon footprint, and so potential methods of reducing the footprint are suggested. Additionally, in order to allow for a similar estimation to be made by others, a python GUI programme is developed. The study concludes that the school needs to address its carbon footprint using the recommended solutions in this study. The study will also hopefully kindle similar studies that can collectively aid in a better understanding of the situation.

Preventing global warming caused by increased CO2 emissions is a major global problem. It is necessary to find and cultivate an efficient industry with a small amount of CO2 emissions and a great impact on the national economy. This article used input–output analysis to quantify the linkage effects on the Korean economy by dividing the Korean industries into 36 categories, according to the OECD (Organization for Economic Cooperation and Development) industrial classification criteria. In addition, the total amount of carbon dioxide emitted during the year was described by its criteria to compare how much of one industry emits carbon dioxide. The analysis shows that Korea still has an economic structure centered on traditional manufacturing and the characteristics of these industries include CO2 emissions. According to the result, in the construction industry, the carbon dioxide emissions are considerably high, but the linkage effects of the industry is small. By quantitatively analyzing the impact of an industry on the economy and carbon dioxide emissions generated in the production process, this study aimed to identify Korea’s eco-friendly and highly related industries with other industries and objectively present sustainable development.

According to the input-output theory, the paper quantitatively analyzes the tourism ecoefficiency of Yangshuo in 2017 by building a tourism eco-efficiency model based on carbon footprint. The research shows that: Firstly, the total carbon footprint of tourism traffic in 2017 is 791.22×106 kg; the total carbon footprint of tourism accommodation is 353.60×106 kg; the total carbon footprint of tourism activities is 123.29×106 kg. Secondly, the 2017 tourism eco-efficiency of the Yangshuo County is 8.05 RMB per kilogram. It refers to the economic profit is 8.05 RMB when 1 kilogram of carbon dioxide is produced, which is relatively efficient compared with other regions. Lastly, the paper makes suggestions with regarding to the optimization of the tourism eco-efficiency.

Abstract The production of concrete is responsible, by some estimates, for as much as 10 percent of global carbon dioxide emissions, enough to be considered a major contributor. Given the impact that has now become apparent, research teams around the world are pursuing a number of impressive and effective technologies to reduce the carbon footprint of concrete production and use as a top priority. Some are being deployed cost-effectively today, while other, potentially even better solutions, are being developed in labs. This article delves deeper into some of these solutions and the challenges in their adoption.

AbstractInternational agreements that aim to reduce carbon dioxide emissions have raised concerns due to the risk of carbon leakage caused by trade liberalization. This study aims to analyse the carbon dioxide emissions related to trade flows for the case of Poland, in order to further investigate the interrelationship between emissions and the quick economic growth the country has faced since 2000. The communist past, the quick liberalization of the economy, the trade opening, entrance to the EU and the intense carbon economy, are some of the characteristics that make Poland an interesting case. The data available data from 1996 to 2008 were collected using the World Input-Output Database and were analyzed using the Input-Output method, and more concretely by constructing a multi-regional input-output model for the years studied. The findings indicate that there were substantial effects on the emissions of Poland that resulted from the opening of the economy and joining the European Union. Poland is a net importer of carbon emissions from other European countries; however, this phenomenon seems to be regulated by EU legislation. Additionally, it was shown that Polish imports from countries with less strict environmental policies significantly embody higher levels of emissions than its exports. This observation calls for stricter environmental regulations to avoid carbon leakage.
