Abstract: Batik industry participate donating environmental pollution by waste produced in the form of liquid, solid and gas. Among the three types of waste that needs to be addressed is waste in the form of CO2 is rated 85% of global warming. This research is conducted to predict of the production of CO2 emissions in PT Danar Hadi to be a green manufacturing company. In this research, the prediction of CO2 emissions is calculated by plant simulation based on the energy comsumption used in supply chain activities during the production period in 2015. The result shows that PT. Danar Hadi produces a total CO2 emissions around 4950 kg. CO2/month while the value of threshold is 8000 kg.CO2/month. That is mean PT. Danar Hadi has excess CO2 emissions around 3050 kg.CO2/month.
