Abstract Emissions of shipping have great influences on atmospheric environment and global climate with the growth maritime trade. Previous studies identified that black carbon (BC) constitutes main aerosol component responsible for light absorption, while organic (OC) was generally considered non-absorbing. Recent indicated components derived from emissions exhibit absorption at short wavelengths (brown carbon, BrC). However, there is a lack quantification regarding effects BrC. This study investigates radiative effect (RAE) BrC, updating models measured BrC ability. Surface concentrations contribute ~ 40% to fossil fuel OC. The annual average RAE +0.15 +0.36 mW m⁻ 2 , peaking in boreal summer. warming 8%–19% relative BC. With low-sulfur standard, increases +0.52 which close BC (+0.52 ) could offset direct cooling sulfate. For aerosols, an important part, whose contribution greater upgrade ship fuels. Graphical
