The growing automotive production and ownership are expected to propel the growth of the advanced carbon dioxide (CO₂) sensors market going forward. Automobiles are motor vehicles designed for road transport, including passenger cars and light commercial vehicles used to move people or goods. The rising number of automobiles is due to a rebound in registrations and growth in the on-road vehicle stock in 2023 compared with 2022. As more vehicles enter service, automakers and tier-1 suppliers integrate advanced CO₂ sensors into cabin air-quality modules to control fresh-air intake, mitigate CO₂ buildup and drowsiness, and meet comfort and safety specifications, increasing sensor units per vehicle. For instance, in May 2024, according to GOV.UK, a UK-based executive agency, there were 41.2 million licensed vehicles in the United Kingdom, up 1% from the end of 2022, evidencing a year-over-year increase in the vehicle park. Therefore, the growing automotive production and ownership is driving the advanced carbon dioxide (CO₂) sensors market.

Key companies operating in the advanced carbon dioxide (CO₂) sensors market are focusing on technological innovation, such as photoacoustic spectroscopy, to enhance sensor accuracy, reduce size and cost, and enable efficient deployment in heating, ventilation, and air conditioning; the internet of things; and building automation systems. Photoacoustic spectroscopy (PAS) is a sensing and measurement technique in which light is absorbed by a gas or material, causing localized heating and pressure changes that generate sound waves. These sound waves are then detected by sensitive microphones to determine the concentration of specific gases, such as carbon dioxide (CO₂), with high precision. For instance, in November 2024, Infineon, a Germany-based semiconductor company, launched the XENSIV PAS CO₂ 5V sensor, a cutting-edge photoacoustic spectroscopy-based solution that enables smart buildings to continuously monitor indoor air quality and optimize heating, ventilation, and air conditioning energy consumption, providing precise, reliable, and energy-efficient climate control while supporting decarbonization goals.
