ABSTRAK . Penentuan Nilai Jejak Karbon (CO2,CH4, dan N2O) dari Aktivitas Kampus di Fakultas Sains dan Matematika Universitas Diponegoro Aktivitas kampus merupakan salah satu dari penghasil jejak karbon. Jejak karbon adalah ukuran jumlah total dari hasil emisi karbon dioksika secara langsung maupun tidak langsung yang disebabkan aktivitas atau akumulasi dari penggunaan prosuk sehari-hari. Belum diketahuinya besar nilai jejak karbon dari aktivitas kampus dan cara reduksi jejak karbon di Fakultas Sains dan Matematika Universitas Diponegoro mendorong untu melakukan penelitian ini. Emisi jejak karbon yang dihitung adalah CO2, CH4, dan N2O yang dinyatakan dalam tonCO2eq. Penentuan nilai jejak karbon di FSM Undip dilakukan dalam 3 lingkup. Perhitungan jejak karbon lingkup satu dari aktivitas pemakaian LPG dan aktivitas transportasi kendaraan operasional, lingkup dua dari aktivitas pembelian dan pemakaian listrik, dan lingkup tiga dari aktivitas transportasi mahasiswa, dosen dan staf kependidikan, pemakaian kertas, dan timbulan sampah. Nilai jejak karbon dihitung berdasarkan metode dari International Panel on Climate Change (IPCC). Nilai jejak karbon yang dihasilkan dari akitivitas kampus di Fakultas Sains dan Matematika Universitas Diponegoro adalah sebesar 468,059 tonCO2eq. Alternatif reduksi dari aktivitas kampus di Fakultas Sains dan Matematika Universitas Diponegoro dilakukan dengan mererapkan tiga skenario. Skenario yang diperkirakan dapat mereduksi jejak karbon adalah beralih menggunakan angkutan umum dan melakukan penghematan listrik dengan besar reduksi yang dihasailkan sebesar 53,5% dan 7,7% dari total jejak karbon yang dihasilkan.

The carbon footprint is a measure from the total amount of carbon dioxide emissions result directly or indirectly, that is caused by the activity or the accumulation of daily products. The amount of value of carbon footprint from campus activity and the way to reduce carbon footprint in Faculty of Science and Mathematics, University of Diponegoro have not known yet. Thus, the writer is encouraged to conduct this study. The emissions of carbon footprint, that are calculated, are CO2, CH4, and N2O. It is then stated in tonCO2eq. The determination value of the carbon footprint in the FSM Undip is done by 3 scopes. In the first scope, the calculation of the carbon footprint comes from the activity of LPG usage and the activity of operational transportation. In the second scope, it comes from the activity of purchasing and consuming electricity. In the third scope, it comes from the activity of students, teachers and educational staff transportation, paper consumption, and waste. The value of carbon footprint is calculated based on International Panel on Climate Change (IPCC) method. The value of carbon footprint that is produced by campus activity in Faculty of Science and Mathematics, University of Diponegoro is 468.059 tonCO2eq. The alternative reduction from campus activity in Faculty of Science and Mathematics, University of Diponegoro is done by implementing three scenarios. These scenarios are expected to reduce the carbon footprint is to switch to using public transportation and to save electricity produced by a large reduction by 53.5% and 7.7% of the total carbon footprint Keyword : carbon footprint, campus activity, IPCC, scope activity, carbon footprint reductio

Carbon-Footprint Policy Of The Top Ten Global Retailers: Contribution To Sustainable Development

The goal of the article is to study the policy of the most prominent ten global retailers relative to the reduction in their carbon footprint. This policy is an integral part of the environmental component of the organizational policy for sustainable development. The research has an exploratory character and is based on the analysis of public information available on the Internet about the objectives, strategies and achievements of the top ten global retailers in the field of carbon-footprint. According to the research objectives, the main results of the study reveal: the organizations that have sustainable development objectives and policies as well as carbon-footprint objectives and policies; the strategies applied for the reduction in their carbon footprint and the results obtained. Are the top ten global retailers a benchmark as regards the carbon-footprint policies? Do they represent a model which has to be followed by other retailers? Several answers may be found in the present article.sustainable development, environmental assessment, ecological footprint, carbon footprint, greenhouse gas emissions, global retailers

Comparing Carbon Footprint Methodologies for SMEs

Carbon footprints are useful and important tools in the fight against climate change, which are now being used widely by larger companies. These large corporations have recognised not only their use as an environmental tool but also their potential to attract customers and reduce costs. However, this is not yet the case for many smaller companies who still consider environmental assessment to be a burden which is too difficult and costly to undertake. In order to encourage small and medium sized enterprises (SMEs) to take more responsibility for their environmental impact, a carbon footprint tool needs to be developed specifically for them, which addresses their particular requirements, namely their lack of knowledge of environmental issues and their lack of time and money. There are currently two basic methodological approaches to produce the conversion factors required to convert quantitative values of material used into the amount of carbon dioxide (CO2) produced by that material usage. One methodology is called lifecycle analysis (LCA) as it looks at all the steps individually throughout the lifecycle of a product and adds them together to form an overall picture. The other, called environmental input output analysis (EIO), uses economic purchase and sales data combined with sector emissions to derive conversion factors based on the amount of money spent within a different sector. This study compares both of these methodologies to determine which of them is most suitable to use in the development of a tool for SMEs. Two tools were created, one based upon each methodology. The most noticeable difference between these two tools was that whereas the LCA tool asked for information in terms of the quantity of a material used, the EIO tool asked for information about the amount of money spent within a sector

Applying consumer responsibility principle in evaluating environmental load of carbon emissions

There is a need for a proper indicator in order to assess the environmental impact of international trade, therefore using the carbon footprint as an indicator can be relevant and useful. The aim of this study is to show from a methodological perspective how the carbon footprint, combined with input- output models can be used for analysing the impacts of international trade on the sustainable use of national resources in a country. The use of the input-output approach has the essential advantage of being able to track the transformation of goods through the economy. The study examines the environmental impact of consumption related to international trade, using the consumer responsibility principle. In this study the use of the carbon footprint and input-output methodology is shown on the example of the Hungarian consumption and the impact of international trade. Moving from a production- based approach in climate policy to a consumption-perspective principle and allocation, would also help to increase the efficiency of emission reduction targets and the evaluation of the ecological impacts of international trade

Estimation of the carbon footprint of student halls of residence in the University of Strathclyde

There is a rapid increase in environmental awareness, which has led to legislative and governmental policy developments addressing the reduction in carbon emissions to the atmosphere. As an example of a local level response, the University of Strathclyde has developed its Environmental Management System. This paper presents the detailed estimation of the carbon footprint of one of the University halls of residence that will assist the University in assessing its environmental impact. The procedure adopted, and the sensitivity studies undertaken, will help to inform the extension of the carbon footprint study to the whole university campus
