Nowadays, Global Warming and Climate Change become the biggest environment issues all over the world, in which greenhouse gas (GHG) emissions are considered to be the main sources.Since the ratification of Kyoto protocol, many countries have developed GHG inventories in order to calculate GHG emissions. The Bilan Carbone model developed by ADEME, is an outstanding tool because it covers all of 6 main GHG and also takes into accountof water vapor and emission from aircrafts. By using easy available data, the Bilan Carbone tool can give an overall of GHG emissions in a territory.Academic institutehowever, is considered to have potential in terms of significantly reduce GHG emissions in its premise because people are capable with knowledge. Estimating GHG emissions in academic institutes has been done and commitment to GHG reduction has been concerned through reduction policy.Asian Institute of Technology (AIT) is also emitting some significant amount of GHG in its premise.The estimation on GHG emissions in AIT campus in the year of 2009 has been done using the Bilan Carbone tool. The sources of GHG emissions covered in the study are energy, excluding energy, materials andproducts purchased (inputs), transportation of goods (freights), transportation of people (travel),solid waste and wastewater (direct waste), and property. The study has shown that in 2009, AIT emitted6,245 tons Carbon equivalent of GHG emissions. Transportation of people is considered to be the biggest emitter, which accounts for 41% of overall GHG emissions inAIT. The average GHG emissions per capita of AIT is 2.08 tCeq. Scenarios for GHG reduction have been proposed according best practices for energy, transportation, solid waste generation and wastewater aspects. The Bilan Carbone was once again used to estimate GHG emissions from each proposed scenario. As a result, energy conservationscenario for energy aspecthas the highest potential in term of reduce GHG emissions, which can reduce GHG emission up to 602 tCeq.And by combining all scenarios together, AIT should be able to reduce about 1,200 tCeq per year.This study has produced a separate spreadsheet for calculating GHG from the whole water supply system. Although reduction scenarios in water and wastewater aspect give very low GHG reduction, it is still important to take into account because it involves people{u2019}s participation. In order to motivate AIT to move towards low carbon campus, itis necessaryto have proper policy guidelines and measurement tools. Regularly receiving information about their own carbon footprint and ways of reducing it, can raise awareness among AIT individuals in terms of reduce GHG emissions.
