Energy

The negative carbon balance of biofuels.

Current approaches to the problem of greenhouse gases, based on the Kyoto protocol, involve searching for ways to reduce emissions. In the best case scenario, palliative measures are proposed, and in the worst case scenario, it is suggested that the problem is getting out of control. The problem can only be resolved by capturing (sequestering) atmospheric carbon. Analysing the negative carbon balance of biofuels will tackle the problem head-on, since it is technically viable and feasible. The key to understanding the concept of negative carbon balance is not to consider it as something that is determined technically, but rather as a strategic choice, whereby farmers and fuel producers can decide how much carbon to return to the soil. We are nearing the time when biofuels, by definition, will have a negative carbon balance, thereby closing the debate about their contribution to the solution of global warming.
Keywords: biofuels, negative carbon balance, global warming.
