Aran Solé, ... Luisa F. Cabeza, in High Temperature Thermal Storage Systems Using Phase Change Materials, 2018. To achieve this, an LCA method is needed to enhance the credibility and convenience of carbon footprint calculation. However, some organizations reported carbon footprint as carbon equivalent (Wiedmann and Minx, 2007), but CO2e is widely used and commonly accepted unit for carbon footprint. Oxford University Press is a department of the University of Oxford. Register for a free account to start saving and receiving special member only perks. Guidelines had been made on these issues from existing assessment standards, but it still needs further improvement. A carbon footprint is the amount of carbon dioxide (CO2) emitted as a direct or indirect result of an activity (Yarrow, Joanna. Every organism is composed of C, H, and O, along with N, which necessitates the availability of these building blocks for life. Applications and corresponding methods of the carbon footprint. 2. Preference for quantization based on GHG activity data multiplied by GHG emission or removal factors. Furthermore, a comparative study of different carbon footprint assessment standards was carried out to identify their similarities, differences and deficiencies. It represents the amount of biologically productive land and sea area necessary to supply the resources a human population consumes, and to assimilate the associated waste. But the notion of what a footprint is does exist. TRB’s National Cooperative Freight Research Program (NCFRP) Web-Only Document 5: Carbon Footprint of Supply Chains: A Scoping Study defines a standardized, conceptual approach to assessing global greenhouse gas (GHG) emissions of the transportation component of supply chains, critiques current methods and data used to quantify greenhouse gas (GHG) emissions, and outlines a work plan to develop a decision tool to help estimate the carbon footprint of the transportation component of supply chains. A sensitivity analysis was carried out for materials extraction and manufacturing phases as they contributed the maximum amount of carbon emissions. Six GHGs in the Kyoto Protocol were selected in the four standards. Until very recently, most people had never heard of a “carbon footprint.” Now, all of a sudden, the phrase is hard to avoid. It is important to note that the combustion of biofuels releases biogenic carbon (i.e., atmospheric carbon that is captured via biomass in the carbon cycle). Among other degrees he holds a Ph.D. in Atmospheric Science. In Eq. Meanwhile, an organization may comprise one or more facilities, which usually apply control and equity share approaches to consolidate facility-level GHG emissions and removals at the organization level. The carbon footprint study is the basis of low-carbon research. Reporting and verifying: Organizations should prepare a report to facilitate inventory verification, participation in a GHG program, or to inform external or internal users. photo acoustic infrared sensors, IR spectroscopy (for CO2 measurement only), and gas chromatography for measuring all the six Kyoto gases (Berg et al., 2006; U.S. (United States Environmental Protection agency). On the contrary, the ISO concerning CFP [21] considers: The sum of greenhouse gas emissions and removals in a product system, expressed as CO2 equivalents and based on a life cycle assessment using the single impact category of climate change. It should include the full range of emissions from activities under operational control. Global warming is a fact, and evolves into a full range of issues of politics, economy, society, technology, environment and ecology on a global scale from a single scientific problem [1]. Activity data and emission factors can come from either primary or secondary sources. Also, it provides underlying standards in designing GHG mitigation projects (ISO, 2006a,b). Carbon Footprint: Global Warming Global warming (a gradual increase in the earth’s and the oceans’ average temperature) and carbon footprint (the amount of greenhouse gases primarily carbon dioxide released into the atmosphere by human activities) coincide because without carbon footprint there would not be any global warming. 2 As discussed, the effects of greenhouse gases and the greenhouse effect has led to the earth’s rapid increase in global warming. Tip – For most plastics processors, a PCF will be unnecessary but processors should be aware that their site carbon footprint data may be requested by customers as part of their PCF. visitors. A product carbon footprint measures the greenhouse gas (GHG) emissions over the entire life of a product (goods or services), from the extraction of raw materials and manufacturing right through to its use and the final re-use, recycling or disposal. Although a LCC is not the scope of this chapter, they report that the environmental impact of a CSP plant in the climate change subcategory is 27.6 kg CO2 eq./MWh. The secondary footprint is a measure of the indirect CO2 emissions from the whole lifecycle of products we use - those associated … So a carbon footprint can be analysed for various different functional units at different scales and using different methods. All material Scope 1 and 2 emissions should be included, but Scope 3 emissions can be chosen to include [14]. The Ecological Footprint measures the amount of biologically productive land and sea area an individual, a region, all of humanity, or a human activity requires to produce the resources it consumes and absorb the waste it generates, and compares this measurement to how much land and sea area is available. Treatments of specific emissions and removals are given in the four standards, although the approach is different and not complete. Similar to the effect of economic activities on the nitrogen cycle through reactive nitrogen mobilization and emissions, the carbon cycle is also hugely disrupted because of economic activities. This sensitivity check describes the effects of input data and electricity on the final result. But other greenhouse gases are also important. Topics: Agriculture, Carbon Footprint, Food, Food Waste, The Food and Agriculture Organization of the United Nations. The results shown in Fig. Dr. Jacobson is a proponent of wind energy and outlined many of his claims about the future viability of wind energy in the TedTalk debate with environmentalist Stewart Brand. His claim can be seen at the 11:45 time stamp of the TedTalk. The carbon footprint is a really bad thing for the environment, but if everyone knew that a carbon footprint is, where it comes from, and how to reduce it, everyone could help the Earth. The carbon footprint study is the basis of low-carbon research. By continuing you agree to the use of cookies. Figure 8.6. © The Author 2013. My Carbon Footprint This essay reviews my personal carbon footprint and discusses ways to manage it and reduce some of the biggest areas of my resource consumption. View our suggested citation for this chapter. When indirect and direct emissions are taken into account, the units of all greenhouse gases or only CO2 are usually not in agreement. It is because the carbon footprint is most probably derived from the global warming potential (Čuček et al., 2012a), and global warming potential is used in commercial LCA software tools, that the term global warming potential is used here and is measured in terms of CO2 equivalence (CO2-eq).
