Sugar crops are a major feedstock for renewable bioethanol production for use as a transportation fuel. Other feedstocks include starch-rich crops such as corn, wheat and cassava. Because it is a clean, affordable and low-carbon biofuel, ethanol from sugar crops has emerged as a leading renewable transportation fuel. Ethanol for fuel can be used in two ways:

• Blended with gasoline at levels ranging from 5 to 27.5% to reduce petroleum use, boost octane ratings and cut tailpipe emissions.
• Pure ethanol – a fuel made up of 85 to 100% ethanol and which can be used in specially designed engines such as flexifuel vehicles.

There are several benefits often recognised from fuel ethanol use. These include

• Cleaner Air. Ethanol adds oxygen to gasoline which helps reduce air pollution and harmful emissions in tailpipe exhaust.
• Reduced Greenhouse Gas Emissions. Compared to gasoline, ethanol from sugar crops significantly cuts carbon dioxide emissions.
• Better Performance. Ethanol is a high-octane fuel that helps prevent engine knocking and generates more power in higher compression engines.
• Lower Petroleum Usage. Ethanol reduces global dependence on oil.

Brazil is the world leader in fuel ethanol production from sugarcane.

Ethanol Production

World fuel ethanol production recovered in 2022, with the former reaching 108.2 bln litres, from 104.5 bln litres in2021, and the latter advancing to 103.8 bln litres, from 101.4 bln litres. Production rose in the US (+1.3 bln litres), India (+1.1 bln litres), and Brazil (+0.7 bln litres), easily offsetting a fall in output experienced in Colombia(-0.05 bln litres).

Ethanol Consumption

The consumption side of the global balance in 2022 also displayed a recovery from the previous year but remained impacted by rising inflation in many parts of the globe, creating challenging economic conditions. With gasoline prices rising quickly, exacerbated by the Ukraine war, ethanol inclusion was able to provide some relief at the pump while bolstering energy security.
