One opportunity to reduce the cost of biofuels is to reduce the cost of bioenergy feedstock, which constitutes a large portion of operating costs, and increase the conversion efficiency from biomass to fuels. Such land conversion may disrupt any future potential for storing carbon in biomass and soil. Barriers and opportunities.

Methyl halides are naturally produced by a number of organisms; the enzyme responsible for this production—methyl halide transferase (MHT)—has been studied in the context of the environmental production of methyl halides, which contribute to ozone depletion.

The area stood to lose billions of dollars of federal funding for a wide variety of projects if the areas air quality didnt improve.
