Select a topic for a paper that will come later. Please review the attached final assignment and write an abstract for a later paper. This class covers multiple topics on sustainability in the business environment. One innovative approach to sustainability that businesses are implementing is an internal carbon fee. Microsoft’s internal carbon fee is much studied because of its success. Other companies are implementing an internal carbon fee ahead of a possible and pending international carbon tax. In fact, globally, 40 countries and 20 cities now have some version of carbon pricing. A carbon tax sets a carbon price by imposing a tax rate on greenhouse gas emissions. Basically, the more carbon a company or manufacturer emits, the higher the carbon tax on that company or manufacturer. The goal of the tax is to drive down GHG emissions. An internal carbon fee works similar to a carbon tax; it is applied internally to spur innovation on how a company can reduce and eliminate GHG emissions, fund environmental conservation projects, and drive sustainability initiatives further into the company’s organizational culture. Businesses do not want to be caught off guard if a carbon tax becomes regulation in countries where they do business. Implementing an internal carbon fee acts as a practice in compliance, and it’s strategically smart.
