The industrial revolution signaled the start of the emission of large amounts of greenhouse gas which over the centuries has led to global warming and climate change. The Kyoto Protocol has introduced adjustment policies to reduce climate change, control greenhouse gas emissions, and save energy consumption for the signatories of the agreement. Globally, there are more than 500 companies, surveyed by the Carbon Disclosure Project, that report their corporate operational greenhouse gas inventories and promote carbon disclosure practices to downstream suppliers. However, the new greenhouse gas emissions regulations and taxes impact sustainable development and also increase enterprise risks and operating costs. In addition to economic risks, enterprises face environmental risks caused by climate changes (e.g., severe global weather changes) that make business operations more challenging. In this study, data are collected to model the existing industrial product demands and greenhouse gas emissions data for the Taiwan TFT-LCD industry. System Dynamics (SD) models are used to forecast the business sector growth and related greenhouse gas emission. The case analysis aligns with the scenarios of carbon emissions regulations and taxation as well as Asian competitors’ carbon reduction plans. The SD simulations assess the viability of investment plans for greenhouse gas reduction programs. The TFT-LCD industry is the focus of study since it is a critical sector of Taiwan’s export manufacturing industry. Normal operations from the TFT-LCD industry provide benchmark data for the SD model. The scenario simulation model is adapted to mimic the reduction plans of similar industries in Taiwan, Korea and Japan. The simulated scenarios are evaluated in terms of their potential environmental impacts and costs. Finally, the assessment of greenhouse gas emission programs is used as a reference to support regional emission reduction policy decision making in the TFT-LCD manufacturing sector.
