Citat:
In the new study, the authors discovered something fascinating. The found that the choices a farmer may make regarding what land to use for biofuels and how much fertilizer to use depend strongly on the price of clean fuels and the cost of greenhouse gases. Simply put, it we put a reasonable price on carbon pollution, farmers will be able to grow switchgrass, poplars, and other species, reduce greenhouse gases, and make money.
But, if there is no cost to carbon pollution, farmers will be motivated to spend more money on fertilizer and that, in the end, will lead to more emissions. While all the scenarios resulted in large emissions reductions compared to gasoline, the reductions were especially large for the scenarios that included a carbon price.
