This research studied the evaluation of greenhouse gas emissions from the organization of one group of transportation and product distribution Industry. ways to reduce greenhouse gases in the industry said. However, in calculating the carbon of the organization in units carbon dioxide equivalent (CO2e)/year arise from the activities of the organization. Study on evaluation during the 1 year (1 January 2014 to 31 December 2014). The scope of study 2 scope is the scope to which 1 include the combustion of fuel in the car transportation and car employees and methane from the septic tank, and the scope to which 2 is use of electricity in office and warehouse. The evaluation results indicate the quantity of greenhouse gas emissions from activities the organization (transport and distribution) in 2014 equals 230.99 tonCO2e/year. The greenhouse gas emissions from activities within the scope of which 1 in parts of the burning fuel oil diesel of the transport car is mainly (71%), especially truck is greenhouse gas emissions to 35.59 tonCO2e /year. This research proposes to reduce greenhouse gas emissions by installing gas system NGV with diesel truck. can reduce the amount of greenhouse gas emissions to 17.89 tonCO2e/year. And the payback period for the cost of gas installations NGV with diesel truck, for about 2 years 6 months. The costs reduce for diesel oil to 110 000baht/year.
