Recent extreme events in Venice lagoon place emphasis on the air quality impact and its relationship with local air emissions production especially waterborne transport. The general concern for the impact of air pollutants on environment and human health has led to the introduction of more restrictive regulations (both marine and inland water vessels) and new technologies have been developed. Despite this, some specific scenarios require different approaches because of their peculiarity. Venice, as a water town, is a very distinctive case where transport is supplied by waterborne systems. Local and regional pollution causes high pollutants concentrations that can duplicate in correspondence of some lagoon's channels especially for NOx. Causes are not completely studied yet, but several small boats navigate in small channels and micrometeorology could have a great impact. In this context ACTV S. p.A. in collaboration with the Dep. DAIS, Ca’ Foscari University, has developed a project aimed to assess ACTV fleet emission estimate (actual and future scenarios) using a mathematical model, WATERBUS (now upgraded v. 2.1). Novelty is in the introduction of specific elements generally not listed causing a misrepresentation of emissions. From results, current situation shows a low percentage impact on total emissions in Venice (1–5%) at province level, but it increases at municipal one (0–20%). Highest percentages refer to NOx. From forecast emission analysis, a new hybrid solution has been evaluated to reduce emission impact of 1–3%. Higher decrease could be extended by an intelligent management of the electric motor of hybrid propulsion in the different lines.
