A Landmark Leap: Brazilian Corn Ethanol's Role in Maritime Decarbonization

The International Maritime Organization's decision on the carbon footprint of Brazilian corn ethanol marks a pivotal moment for maritime transport. With corn ethanol's carbon emissions set at 20.8 grams of CO2e per megajoule, it paves the way for its potential as a key decarbonization fuel in the shipping industry.

The International Maritime Organization (IMO) has taken a landmark step by defining Brazilian corn ethanol's carbon footprint, marking a turning point for maritime transport as a future market. Industry executives believe this decision places corn ethanol at the forefront of efforts to decarbonize shipping fuels.

In May, the IMO set the carbon footprint of Brazilian corn ethanol at 20.8 grams of carbon dioxide-equivalent (CO2e) per megajoule specifically for biofuel produced from Brazil's second-corn crop. This compares favorably against the current average greenhouse gas fuel intensity of 93.3 grams of CO2e per megajoule in shipping, according to the IMO.

Gustavo Mariano, Inpasa's vice president of trading, hailed this development as a 'historic and symbolic milestone', reinforcing Brazilian corn ethanol as a viable decarbonization fuel. With regulatory approval for use in shipping, corn ethanol could benefit from a premium on greener fuels. The large scale of the global shipping market indicates a need for all sustainable biofuels, including corn ethanol, to complement existing options like sugarcane ethanol and biodiesel.
