This paper presents a review of carbon dioxide (CO2) emissions from transportation in an attempt to establish a quick and suboptimal update of the methods used to calculate and analyze CO2 emissions from transportation. Transportation is the largest contributor to air pollution through the release of high amounts of CO2 gas into the atmosphere. The methods for calculating and analyzing the carbon footprint of transportation; which is of critical importance in the management of greenhouse gases that contribute to global warming; are still being developed. However; there are some differences in the definitions and methods used to calculate the carbon footprint of transportation in previous studies. This review focuses on the similarities of the methods used to measure CO2 emissions as well as the analyses used to evaluate the emissions. This paper will also highlight the advantages and limitations of each research work. By doing this; the present study contributes to the selection of appropriate methods for calculating CO2 emissions from transportation and draws attention to environmental issues. It is hoped that the implementation of the most appropriate framework will help to reduce CO2 emissions from transportation

The Impact

The purpose of this paper is the international tourism have impact on economic growth and carbon dioxide (CO2) emissionsin ASEAN Five (Indonesia, Malaysia, Philippines, Thailand, Singapore) or not. There are increase in tourism receipts, GDP, and FDI as well as CO2 emissions approximately 9%, 5%, 4% and 26% respectively. They are always increasing, but is there any relation between international tourism, GDP and carbon dioxide (CO2). This research employs data from 1995 to 2018 to examine long-run equilibrium relationships between tourism, CO2, economic growth and foreign direct investment (FDI). Panel analysis with unit root and cointegration test approachis utilized. This paper found that there is a long-term equilibrium relationships between each variable.The tourism receipt, FDI and CO2 emissions affect economic growth positively and statistically significant. In addition, economic growth affect CO2 emissions while tourism does not affect CO2 and FDI indicates a negative relationship on CO2 emissions. Finally, the paper reveals that international tourism receipt affect economic growth but does not affect CO2.

Carbon footprint is the amount of a greenhouse gas (GHG) produced as a result of human activities, usually expressed in equivalent kilograms of carbon dioxide (CO2). As the amount of greenhouse gases emission increases, the global temperature increases. In the context of a global awareness of the climate change, carbon footprint has recently become extensively calculated and ways to reduce it are proposed. The purpose of this research is to calculate the amount of carbon footprint discharged by students in College of Engineering (COE), Universiti Tenaga Nasional (UNITEN). From this research a model to calculate the carbon dioxide emission released from the activities done by the COE students particularly, is developed. Literature reviews are done leading to an explanation of what emission categories should be presented in a CO2 calculation for a university. This includes emission sources in each buildings, activities and services in COE particularly. Conducting survey is one of the methods to get the data from the students and staffs directly. From this data, the calculation is done and tabulated in the Excel template. From this template model, the carbon footprint for each or total students of COE can be known. Referring to this data, CO2 reduction strategy in COE particularly and UNITEN generally can be proposed.

The paper proposes a two-step evaluation process to assess the developed driving cycles for carbon dioxide emissions. The first step is to compare the driving operating mode distributions from developed driving cycles with real world ones. The second step is to predict the carbon dioxide (CO2) emissions by using the developed driving cycles under the latest version of MOVES, MOVES2010 framework, which are then compared with and evaluated by the real-world CO2 emissions. Evaluation results show that the driving cycles developed by the driving operating mode distribution measure result in more accurate CO2 emission estimations.

Food Production System

Traditional Cambodian food has higher nutrient balances and is environmentally sustainable compared to conventional diets. However, there is a lack of knowledge and evidence on nutrient intake and the environmental greenness of traditional food at different age distributions. The relationship between nutritional intake and environmental impact can be evaluated using carbon dioxide (CO2) emissions from agricultural production based on life cycle assessment (LCA). The objective of this study was to estimate the CO2 equivalent (eq) emissions from the traditional Cambodian diet using LCA, starting at each agricultural production phase. A one-year food consumption scenario with the traditional diet was established. Five breakfast (BF1–5) and seven lunch and dinner (LD1–7) food sets were consumed at the same rate and compared using LCA. The results showed that BF1 and LD2 had the lowest and highest emissions (0.3 Mt CO2 eq/yr and 1.2 Mt CO2 eq/yr, respectively). The food calories, minerals, and vitamins met the recommended dietary allowance. The country’s existing food production system generates CO2 emissions of 9.7 Mt CO2 eq/yr, with the proposed system reducing these by 28.9% to 6.9 Mt CO2 eq/yr. The change in each food item could decrease emissions depending on the type and quantity of the food set, especially meat and milk consumption.

Due to manufactured technology enchantment the living being has much convenience and luxury. Though, at the same time, our current existence is doing damage to the environment. Like water pollution, air pollution and Carbon dioxide (CO2) emissions on so forth. But CO2 emissions are the one of the major reason polluting the environment. Furthermost of what we utilise in our daily life lead to emitting CO2 into the environment. Due to this it leads to global warming and climate change problems. Therefore, carbon auditing (Carbon Footprint Analysis) is the first essential step to review the use of energy, to improve energy conservation and to allow building to go green. For this reason we need carbon audit to reduce usage raw materials, waste generation so on so forth to minimise GHG emissions .“CARBON AUDIT” is conducted within the building’s boundary which includes the following stages:- People Survey to gather employee-level data, Building Survey to gather building-operation data, Carbon Footprint Analysis to evaluate the greenhouse gas (GHG) emission and Final Carbon Audit Report to provide tailored recommendations for going green along with action plan to get started

Abstract. Most atmospheric scientists agree that greenhouse gas emissions have already caused significant changes to the global climate system and that these changes will accelerate in the near future. At the same time, atmospheric scientists who – like other scientists – rely on international collaboration and information exchange travel a lot and, thereby, cause substantial emissions of carbon dioxide (CO2). In this paper, the CO2 emissions of the employees working at an atmospheric research institute (the Norwegian Institute for Air Research, NILU) caused by all types of business travel (conference visits, workshops, field campaigns, instrument maintainance, etc.) were calculated for the years 2005–2007. It is estimated that more than 90% of the emissions were caused by air travel, 3% by ground travel and 5% by hotel usage. The travel-related annual emissions were between 1.9 and 2.4 t CO2 per employee or between 3.9 and 5.5 t CO2 per scientist. For comparison, the total annual per capita CO2 emissions are 4.5 t worldwide, 1.2 t for India, 3.8 t for China, 5.9 t for Sweden and 19.1 t for Norway. The travel-related CO2 emissions of a NILU scientist, occurring in 24 days of a year on average, exceed the global average annual per capita emission. Norway's per-capita CO2 emissions are among the highest in the world, mostly because of the emissions from the oil industry. If the emissions per NILU scientist derived in this paper are taken as representative for the average Norwegian researcher, travel by Norwegian scientists would nevertheless account for a substantial 0.2% of Norway's total CO2 emissions. Since most of the travel-related emissions are due to air travel, water vapor emissions, ozone production and contrail formation further increase the relative importance of NILU's travel in terms of radiative forcing.
