The following carbon footprint calculation is based on my personal boundary that the amount consumed by myself. The amount consumed is calculated from February 2015 when I moved to the new apartment where I am living to February 2016 which is easier to calculate.
Explanation of the calculation of carbon footprint
The amount of emission of carbon dioxide can be calculated by the ISA-GHG calculator based on the dollar amount spent on individual activity. Generally, my weekly budget could be divided into three parts: rent, entertainment cost and food cost on supermarkets. Rent accounts for the largest proportion of it, followed by food on supermarkets and entertainment cost. Specifically, individual spending can be evidenced by the receipts and I having been recoding my weekly expense for a long time so they are all reliable sources for the carbon footprint calculation. Moreover, I am living in a shared house with my flatmates, the electricity bill, rent and water bill should be divided by the number of people living in the department to calculate an accurate number.
The classification of GHG emission According to the classification of GHG emission, my daily activities can be divided into Scope 1, Scope 2 and Scope 3. Under the food section, I have the direct ownership of those food and vegetable so activities related to them are considered as Scope 1.
Under the Housing section, my activity in the past year didn't get involved to natural gas and construction and maintenance. Conventional Electricity is in Scope 2 and rent expense is considered as Scope 3.Moreover, I don’t own my owe car so I have no relation to the private car services or petrol fees. The main transport I use is public transport and it can be classified into Scope 3 as the activities is controlled by other company.
Under goods sections, they consist of furniture, clothes, shoes and others could be included in Scope 1 because I have direct ownership to those items.
In terms of Services, water, wasted and sewerage, communication, insurance, government services and defence, entertainment could be considered in Scope 3 as I purchased these services from outside and I cannot control the emission produced.
Source of uncertainty
The ISA-GHG Calculator operated base on the input of dollar amount spent on individual activities, which means it required a huge amount of accurate information before the calculation.…...

Ecological Footprint

...Name Tutor Course Date Ecological footprint Introduction The planet Earth is the only planet that supports and sustains human life. The human activities carried out on the planet are gradually making the planet unfavorable to live on (Perman 81). Ecology involves the study of relationships between living organisms and their usual natural environment. This paper will define ecological footprint, present a deep understanding of the ecological footprint and show how it applies in measuring the peoples’ effects to the environment. The paper will also explain how the ecological footprint can be used in making choices that go in line with people’s lifestyles. The principles of ecological footprint date back to literatures related to geography, ecology and economics. However, the idea of the earth’s ecological footprint has been present since early 90’s (Wackernagel 35). William Rees in 1992 produced the first academic publication on ecological footprint. The concept of ecological footprint and calculation criteria was later developed by Mathis Wackernagel as a PhD dissertation under the supervision of Rees at British Columbia University in Vancouver. Originally, the concept was called the appropriated carrying capacity. Rees later came up with the ecological footprint term in order to ensure that the concept is accessible. The ecological footprint in the planet has transpired as the earth’s vital gauge of the individual’s demand on the environment and......

Carbon Footprint

...Carbon footprint. What is your carbon footprint? That’s a question I was not prepared for. I had no clue what a carbon footprint was or how to even answer that question. I was worried I would never understand what was being asked of me. Luckily my sociology teacher provided a website that would give me better understanding of what my carbon footprint was and how to break it down. The Nature Conservancy Carbon Calculator on Nature.org had questions for me to answer that would determine how much carbon I was responsible for. According to the carbon calculator my estimated greenhouse gas emission is 39 tons of carbon dioxide a year whereas the average person releases 27 tons in a year (Nature.org). Out of the estimated tons of carbon I release in a year, 83.3 % has to do with home energy. I have a detached, single family home with 2 bedrooms, and that makes my estimated impact jump to 27 tons of carbon dioxide a year (Nature.org). When I was heating and cooling my home I didn’t think twice when adjusting my thermostat. If I was hot I would turn the air down, when cold the heat went up. By doing that I was causing an estimated impact of 2.5 tons of CO2 per year. (Nature.org). There are other things in which I produce different amounts of CO2, driving my big Ford F150 roughly 30 miles in a week puts out an estimated 1.4 tons of CO2 per year (Nature.org). I eat red meat most days but I don’t eat it with every meal. My red meat consumption has an estimated impact of 4.1 tons of......

Lit Review Household/Carbon Footprint

...Literature Review on households / individual carbon footprints Households’ carbon footprints have fluctuated on a regular basis for many years. Why is this the case? Surely our carbon footprint should be reducing with ever increasing pressures from Governments and NGOs to consider the consequences of our lifestyles on the future of our planet. This is not the result though, “our needs and desires are expressed in the consumer demand for commodities, and it is this demand for goods and services which drives the production processes that consume resources” (Druckman, Jackson, 2009). Druckman and Jackson aim to understand carbon dioxide emissions from economic activity and “explore the variation in carbon footprints across different segments of society.” Druckman and Jackson found that affluence was a big factor in determining carbon emission disparities but it was not the only factor. Using a Local Area Resource Analysis (LARA) model, they realised that dwelling type and household composition also played a part. Using a variety of different methods and data, Druckman and Jackson tried to understand the variations in the UK’s carbon emissions. Examples of the different types of data in the literature were: “Allocation table for high level functional uses”, trends in CO2 and household expenditure in the UK and “CO2 emissions attributable to Supergroups”. In almost all research projects there are assumptions and limitations and this was also the case in this literature. Druckman......

Carbon Footprint

...The term ‘carbon footprint’ has become tremendously popular over the last few years and is now in widespread use across the media. With climate change high up on the political and corporate agenda, carbon footprint calculations are in strong demand. Numerous approaches have been proposed to provide estimates, ranging from basic online calculators to sophisticated life-cycle analysis or input-output-based methods and tools. Despite its ubiquitous use however, there is an apparent lack of academic definitions of what exactly a ‘carbon footprint’ is meant to be. The scientific literature is surprisingly void of clarifications, despite the fact that countless studies in energy and ecological economics that could have claimed to measure a ‘carbon footprint’ have been published over decades. This report explores the apparent discrepancy between public and academic use of the term ‘carbon footprint’ and suggests a scientific definition based on commonly accepted accounting principles and modelling approaches. It addresses methodological question such as system boundaries, completeness, comprehensiveness, units and robustness of the indicator. >>> Processes causing greenhouse gas (GHG) emissions benefit humans by providing consumer goods and services. This benefit, and hence the responsibility for emissions, varies by purpose or consumption category and is unevenly distributed across and within countries. We quantify greenhouse gas emissions associated with the final consumption...

Carbon Footprints

...CARBON FOOTPRINT For the past few years, our beloved “earth” is going deeper and deeper into the quagmire of global warming. This is indeed an alarming situation and to get it round each and every individual has to play an effective role. This is possible only if we are cognizant of the factors which are creating this problem of global warming. Many of us would have heard the word “carbon footprint” and this is where the whole problem lies! Carbondioxide (CO2) is a gas in an atmosphere that absorbs and emits radiation within the thermal infrared range. This process is the fundamental cause of the global warming so if we can reduce CO2 emission, gigantic climate changes ,global warming and their hazardous effects can be reduced. Your “carbon footprint” is the sum of all emissions of CO2, which were induced by your activities in a given time frame. The carbon footprint is a very powerful tool to understand the impact of personal behaviour on global warming. Most people are shocked when they see the amount of CO2 their activities create! If you personally want to contribute to stop global warming, the calculation and constant monitoring of your personal carbon footprint is essential. Here are some of the ways which can help to abate the carbon footprint: • Go native: Use native plant species to landscape around your home or business. The plants will probably grow better in a familiar environment, and the plants may also get shipped a shorter distance to get......

Carbon Footprinting

...CARBON FOOTPRINTS OF STUDENTS OF SCMS-UG, PUNE Name : Amogh Koranmath Class : TY -C PRN No: 11020621035 INTRODUCTION What is Carbon Footprint A carbon footprint is defined as the total amount of greenhouse gases produced to directly and indirectly support human activities, usually expressed in equivalent tons of carbon dioxide (CO2). In other words: When you drive a car, the engine burns fuel which creates a certain amount of CO2, depending on its fuel consumption and the driving distance. (CO2 is the chemical symbol for carbon dioxide). When you heat your house with oil, gas or coal, then you also generate CO2. Even if you heat your house with electricity, the generation of the electrical power may also have emitted a certain amount of CO2. When you buy food and goods, the production of the food and goods also emitted some quantities of CO2. Your carbon footprint is the sum of all emissions of CO2 (carbon dioxide), which were induced by your activities in a given time frame. Usually a carbon footprint is calculated for the time period of a year. A carbon footprint has historically been defined by Championne as "the total sets of greenhouse gas emissions caused by an organization, event, product or person. Greenhouse gases can be emitted through transport, land clearance, and the production and consumption of food, fuels, manufactured goods, materials, wood, roads, buildings, and services. For simplicity of reporting, it is often expressed in......

Carbon Footprint Hypothesis

...Running head: CARBON FOOTPRINT HYPOTHESIS COMPARISION Carbon Footprint Hypothesis Comparison Lori Jaide Watson Kaplan University SC225: Environmental Science: Ecosystems, Resources, and Carbon Footprints Anna Spaulding, Instructor February 25, 2013 Science is an on-going and constantly expanding observation of the scientific method continuously resulting in revision. As a result, research is reviewed and revised which allow scientists opportunities to collect discoveries of world-wide new evidence. Once new discoveries are established and hypothesis tested, science is altered. Consequently, there are some applicable rules relevant to scientific concepts specifically the steps leading to the Scientific Method that affirm the validity of research. Theories of law and nature are subject to change, based on new observations (Wiley, 2010). Testing and observation allows proven evidence (scientific method) that become facts and not fiction. I was compelled to apply the scientific method in real life because I am making a conscious effort to think more deeply about the impact of lifestyle choices on overall carbon emissions. I recently considered earth-friendly ways to commute to work and give my car a break. I decided to walk to work because driving emits carbon dioxide and is a contributing factor to global warming. I now walk to work three days out of the week instead of two days to reduce greenhouse gas emissions, save money on fuel, and have influence......

Carbon Footprint

...Carbon footprint Name Institutional Affiliation According to the carbon calculator, my greenhouse gas emission was estimated to be 27 tons per year (Lynas, & HarperCollins, 2007).  Out of this emission, the amount of carbon dioxide produced per year was 83.3%. This percentage of carbon dioxide is mostly contributed by home energy. The high amounts of greenhouse gases produced is due to the usage of hydrocarbons in heating and lighting where an estimate of 2.5 tons of carbon dioxide are produced. In addition, my vehicle emits an extra estimate of 1.4 tons of carbon dioxide for 30 miles in a week. My consumption of meat has an impact of 4.1 tons of carbon dioxide per year. All these personal activities made me realize the personal impact an individual can have to the environment (Bishop, 2008).  From the learning outcome, I really feel I have a role to play in the environment. This is because I was not aware of the harm I was causing to the environment in contributing to greenhouse effects. I now appreciate the importance of keeping low personal carbon footprint (Bishop, 2008).  After calculating my carbon footprint, I realized I had an impact on the environment. This impact is much more than I am supposed to and hence the need to try my level best to lower the amount of carbon dioxide I contribute to the environment (Lynas, & HarperCollins, 2007).  Part of my life contributing the most carbon is lighting and heating where I mostly use hydrocarbons for such......

Calculation of Household’s Ecological Footprint Using the Calculator Developed by Wackernagel

...ECOLOGICAL FOOTPRINT Mohammad Khanbashi Managing for Sustainability In 2007, the Earth’s people used about 50% more natural resources than the planet could regenerate.1 A measure of the impact humans have on the environment is called an ecological footprint. A country’s ecological footprint is the sum of all the cropland, grazing land, forest and fishing grounds required to produce the food, fiber and timber it consumes, to absorb the wastes emitted when it uses energy and to provide space for infrastructure. WWF’s Living Planet Report 2010 found that in 2007 the global ecological footprint was 18 billion hectares. This means that the Earth’s people needed 18 billion hectares of productive land in order to provide each and every person with the resources they required to support their lifestyle 1 . Living Planet Report, WWF, GFN and ZSL, 2010 and to absorb the wastes they produced. The bad news is that there were only 11.9 billion global hectares available. In Australia, we’re consuming more than three times our fair share of the planet’s natural resources. If we continue these consumption patterns, we will face an ecological overshoot that will have far-reaching future consequences for people and nature. Australians have one of the largest environmental footprints per capita in the world, requiring 6.8 global hectares per person. If all people consumed the Earth’s resources the way that we do in Australia, it would take the resources of......

Carbon Footprint

...Special report│Carbon management Towards a carbon footprint sustainable supply chain As the planet is heats up, so do mandates for manufacturers to reduce their carbon emissions. While manufacturers have been doing their bit in their manufacturing units, their carbon efficient initiatives has ceased to become a mere CSR activity, a movement, or a political leaning. It has transformed into business and economic viability. Today, manufacturers are pushed out of their production silos to consider the entire supply chain and look for new opportunities to erase the carbon footprints effectively – from sourcing to production, to distribution and product afterlife. The need today is for manufacturers to integrate an effective carbon reduction strategy into supply chain to reduce footprint, enhance their corporate image and reap the cost advantage. Attempting to please the ecological police with environmental initiatives and stakeholders with improved savings upon energy consumption, manufacturing companies have come a long way in their energy efficient initiatives. They have come out of their manufacturing facilities’ silos and have started to take an integrated view of their supply chains to erase the most villainous presence of the ‘carbon footprints’. Although manufacturing companies traditionally limited their supply chain optimisation vision to minimising costs to partners in the supply chain and maximising service to the customers, the current scenario is quickly......

Carbon and Water Footprint

...What is Your Carbon Footprint? Carbon footprint, what is that? It is a measurement of the environmental impact of a particular individual or organization’s lifestyle or operation, measured in units of carbon dioxide. Upon calculating my own carbon footprint, the results were 19,373 pounds of carbon dioxide per year. Compared to the United States average of 20,750 pounds. Surprisingly that is only a difference of 1,377 pounds. In comparison to other countries like China, which are approximately 21,995 pounds and India at an estimated 1,245 pounds. The United States falls in the median at 20,750 pounds. That is a difference of 4% with China and 13% with India. What makes the difference? Any attempt to decrease the effects of your carbon emissions by either participating in other activities which have the same end results. There is a plethora of ways to offset your carbon emissions. For instance, on the road remember to stay intact with your vehicle’s maintenance and upkeep. Ensure you are getting tune-ups according manufacturer’s specifications for your make and model. Check your vehicles tire pressure and fluids, often. Reduction in the load you carry in your vehicle can also help. Also, utilize renewable fuels like E85. At home, switch out your regular light bulbs for the energy efficient bulbs. Turn off and or unplug any electronic devices when not in use.

Carbon and Ecological Footprint

...Carbon Footprint versus Ecological Footprint The term carbon footprint refers to the whole set of green house gases or emissions caused by an event, an organization, a person, or even a person. However, this definition requires a vast amount of data which takes forever to collect. As a result, this renders it impracticable, and experts have to look for a definition they can be able to work with. The most accepted definition of the carbon footprint defines the term as the entirety of the amount of methane and carbon dioxide gases produced by a defined population, activity or system, putting into consideration all the sinks, storage and sources within the temporal and spatial boundaries of either the population, activity or system. Greenhouse gases, which are made up of mostly carbon dioxide and methane gas can be emitted during activities such as land clearance, transport using means which use fossil fuels as a source of energy, production and subsequent of fuels, foods, manufactured goods, material, and building roads and buildings. The carbon blue print of a nation, an individual or that of an organization can be determined by undertaking an assessment of greenhouse gas emission. Once the footprint’s size is known, measures can be used to try and reduce it. Some of the measures taken by individuals, nations and organization to reduce their carbon footprint include carbon offsetting, technological improvements, and better product and process management.
