Scaling of industry sales statistics enabled the discrepancy to be attributed to the use of ancillary solvent products such as screenwash and deicer which are not included in internationally applied vehicle emission methodologies. While some VOCs are released in exhaust, others may arise from an unexpected source—e.g.,
