The study looked at how Taiwan’s manufacturing industry used energy and produced carbon emissions from 1982 to 2014. By using a method called the Logarithmic Mean Divisia Index, researchers split energy usage into three parts: the types of fuel used, how much energy each sector needed, and changes in the industry's setup. They discovered that energy use and carbon emissions were closely connected in Taiwan. Energy use was mostly affected by how much each sector needed. Over time, changes in how the industry worked and the fuel mix made a bigger difference in reducing energy use. To help the environment, Taiwan should charge for carbon emissions, encourage energy-saving technology, and improve their electricity market.
