Additionally, the report states that the issue of sustainability may also become a factor that impedes the international biofuels market. Some European countries seem to be in the early stages of requiring that imported biofuels come from sustainable sources.
Howse believes that there are two primary reasons why people shy away from discussing the biofuels market openly. The first is that it's a relatively new market. The second is because energy issues are usually tied to national security. He says, "Once you get past that threshold, you can have trade negotiations that are explicitly targeted at biofuels." The paper suggests that governments and international organizations such as the World Trade Organization start working together to develop acceptable standards.
