What is Life Cycle Assessment?

Climate change is probably the most important environmental theme nowadays. Since its effects are global, it is the focus of attention by both the scientific community and governments worldwide. Companies increasingly recognize their role in greenhouse gases emissions, and are progressively taking measures to assure that they decrease their impact by reducing their carbon emissions. Carbon dioxide is the main focus of this effort, but it is not the only substance that contributes to global warming.

One of the themes contemplated in LCA studies is climate change. The climate change theme is calculated as the emission of greenhouse gases that occur during the studied life cycle. Therefore, this theme measures the anthropogenic contribute to the increase of global planet temperature.

LCA is, then, a viable way for companies to calculate their carbon footprint. It has the advantage of determining direct and indirect emissions, and considering not only carbon dioxide emissions, but also other substances that contribute to global warming.

The use of LCA to calculate carbon footprints has one further advantage. Since it follows guidelines from ISO standards, the LCA method yields comparable results between products. If different and unstandardized methodologies are used, then results for different products of the same kind are not clear and comparable, and therefore consumers cannot really know which are environmentally better.
