 It is important to realize low-carbon society in the world. Not only industries but also the universities face with this problem. We purpose to grasp the actual conditions of carbon emission and get the base information of University in order to find the useful method to reduce CO2 emission. We conducted benchmarking of 60 National Universities in Japan which are obliged to make the environment report by Environmental Consideration Law. This paper focus on energy, which is electricity, heavy oil, heating oil, gasoline, gas oil, city gas, propane gas and CO2 emission in fiscal year of 2005, 2006 and 2007.
Amount of CO2 emission generated from non-renewable resource (by conversion factors of Local Suppliers) is 1.79 million ton-CO2 /yr in 2005, 1.69 million ton-CO2 /yr in 2006, 1.86 million ton-CO2 /yr in 2007, and it correspond to 0.14% of total emission in Japan. This study also shows that 34 universities reduced in total amount of CO2 emission (by default conversion factors of law) in 2007, compared to 2005.
 The maximum value of CO2 emission per unit floor area is more than 5 times larger than the minimum. 4 universities have succeeded in reduction of both total amount and amount per gross floor area for these 2 years.
 It is necessary to gather and analyze more data for considering countermeasures. Benchmarking of CO2 emission is effective to stipulate concrete action.
