An estimate of the annual global methyl bromide (CH 3 Br) emissions from automobile exhausts has been determined by extrapolating the results of a field study conducted in the United Kingdom (UK). A strong linear correlation was observed between the CH 3 Br and carbon monoxide (CO) concentrations of roadside air in three cities. This correlation and knowledge of the UK CO emissions was used to estimate the source strength of CH 3 Br from automobile exhausts in the UK (0.04 ktonnes yr −1 ). Further extrapolations lead to a value of 1.5 ktonnes yr −1 (with an upper limit of 3.0 ktonnes yr −1 ) of CH 3 Br released globally to the atmosphere from automobile exhausts.
