The concept of climate change and the need to reduce carbon emissions is far from widely accepted in the U.S., but viewpoints are beginning to change, largely due to customer demand. Japan and the European Union were early converts to the argument that we are changing our planet’s weather patterns, and much of the current legislation is appearing in these countries. Given the trend, though, the U.S. will not be far behind.
We have all heard a great deal about carbon emissions and the ways both individuals and companies can reduce electricity usage and save on transportation. That’s the easy part. The expenditure is simple to quantify, and the carbon emissions are easy to measure. The much larger challenge for companies is measuring the carbon footprint of a product, defined here as the total set of greenhouse gas emissions caused by the production of one unit of a product. This implies knowledge of the carbon emissions released at each stage of the supply chain and production as well as the transportation of all the raw materials and components. To offer an example, the Carbon Trust, an independent company funded by the UK government, recently illustrated the components that create the carbon footprint of a can of cola.
