Transportation greenhouse gas emissions are a problem. Transportation is the number-one source of greenhouse-gas emissions in the U.S., supplanting electrical power generation in recent years. While it is expected that transportation-based greenhouse gas emissions are going to decrease as electric vehicles become more popular, those vehicles require substantial investment, both from the industrial sector to build more electric vehicles, from the transportation sector, where charging infrastructure must be built out, and from the consumer when they purchase the vehicles.
Biofuels hold the key to reducing carbon dioxide emissions today. Many biofuels already meet the standards set for transportation fuels, meaning they can drop in and do the job right now. Because they meet the standard, they can be combined with other fuels in the tank with no negative impact on operation. The result: Biofuels create a solution that can be implemented right now, in the cars, trucks, boats, and planes in use today.
