The footprint of oil typically considers combustion emissions, neglecting extraction emissions. This study shows that production declines with depletion for 25 significant oil fields, whilst emissions increase through greater energy expenditure.
Transportation fuels such as diesel contain organosulfur molecules that, when combusted, form sulfur oxides that are toxic and poison vehicles' catalytic convertors. Now, a method is demonstrated that can reduce the sulfur concentration of diesel fuel to very low levels at low temperatures and pressures.
