Vessel owners and operators are increasingly consider- ing hybrid and fully electric vessels as part of efforts to reduce emissions.

Crowley said the eWolf will generate 178 tons less of nitrogen oxide (NOx), 2.5 tons less of diesel particulate matter and 3,100 metric tons less of carbon dioxide (CO2) over the ? rst 10 years of its operations – the equivalent of removing 350,000 gallons of gas from use, according to

EPA calculations.

Crowley in 2021 announced its commitment to reach net- zero emissions across all scopes by 2050. The Jacksonville,

Fla.-based company estimates it will reduce overall emissions by 4.2 million metric tons of greenhouse gases per year.
