All across the world, colleges and universities are looking to a sustainable future by working to become carbon neutral. Universities are taking responsibility for their environmental impact and are working to neutralize those effects. To become carbon neutral, universities are working to reduce their emissions of greenhouse gases, cut their use of energy, use more renewable energy, and emphasize the importance of sustainable energy sources.〔 Universities that have committed to becoming carbon neutral have recognized the threat of global warming and are therefore committing to reverse the trend.〔 ==Definitions== (詳細はCarbon Neutral: a term that recognizes all of the actions of a person, project or an institution that result in zero net carbon dioxide emissions. It can be achieved by increasing energy efficiency and improving energy conservation, as well as by using renewable energy〔 * Carbon Offset: an emission reduction credit from a project that results in less carbon dioxide or other greenhouse gases in the atmosphere than would otherwise occur. Carbon offsets are usually measured in tons of CO2 and can be created by renewable energy projects, energy efficiency, and land use and agriculture based projects〔 * Sustainable: a method of harvesting or using a resource so that the resource is not depleted or permanently damaged; of or relating to a lifestyle involving the use of sustainable methods 〔 * Carbon Footprint: a measure of the amount of carbon dioxide that is put into the atmosphere as a result of an individual's actions; driving, flying, home heating and cooling, as well as electricity use are some of the common activities that add to your carbon footprint 〔 * Carbon Calculator: measures an individual's or institution's impact on the climate by estimating how many tons of carbon dioxide and other greenhouse gases an individual's choices create each year. More than 90% of U.S. colleges and universities, and many outside the US, use the Clean Air-Cool Planet (Campus Carbon Calculator )—the tool (recommended by the U.S. EPA ), the ACUPCC,〔ACUPCC Implementation Guide, page 5; http://www2.presidentsclimatecommitment.org/html/documents/ACUPCCGHGInv_Br_vFinal.pdf〕 and others—to (do their greenhouse gas inventories ) and climate action plans 〔 * Carbon Credit: a permit that allows the holder to emit one ton of carbon dioixide; credits are awarded to countries or groups that have reduced their greenhouse gases below their emission quota 〔 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Campus carbon neutrality」の詳細全文を読む スポンサード リンク
