Asker's air quality benefits from the Oslofjord region's maritime ventilation southwest of Oslo, with vehicle traffic on the E18 motorway and surrounding affluent residential and technology corridor contributing local sources. The Oslofjord's consistent maritime ventilation provides reliable background management, while the surrounding Vestmarka forest provides clean-air buffering and Asker generally maintains among the Oslo region's more moderate residential environments throughout most of the year.
