CO 2 emissions, on average 2.67% from pellets and 2.27% from wood chips, were elevated comparing with a typical outdoor air level of 0.03–0.05% (300–500 ppm). The level of emissions of individual components also changes during the grilling cycle, and depends on the type of combusted wood, grilling conditions and fuel moisture content.
