Report

The Europe Gas Sensors Market size is estimated at USD 2.24 billion in 2025, and is expected to reach USD 3.53 billion by 2030, at a CAGR of 9.52% during the forecast period (2025-2030).

Key Highlights
- Governments' increasing attention on emission control and energy efficiency regulations has led to gas sensors in European nations such as Germany, France, and the United Kingdom. The variables that would drive market expansion in this area include an expanding end-user base and expanding avenues for the usage of gas sensors.
- The European gas sensor market is projected to continue to be dominated by automotive and transportation applications. In Europe, strict environmental and safety requirements require all vehicle and transportation OEMs to include gas sensor technologies in their offerings.
- Additionally, the IIoT is also advancing in the region. Customers are becoming more interested in IoT gas detectors, and players in the industry are working on establishing a product range tailored to IoT solutions. The necessity for wireless detectors owing to the requirement of continuous and real-time monitoring and detection of emissions is predicted to drive up demand for gas detectors in recent years and the coming years.
- Carbon dioxide sensors are primarily used in households, schools, offices, and hospitals to monitor indoor air quality. Similarly, these sensors are also utilized for real-time monitoring of agricultural goods' freshness, quality, and safety. Therefore, as excessive carbon dioxide exposure can cause health problems such as headaches and restlessness, the need for carbon dioxide sensors is rapidly increasing in this region.
- However, the high initial cost of the sensors acts as a significant barrier to adoption, stifling market growth. Also, the costs of production for gas sensors and detectors have been steadily rising due to recent technological changes. While the market incumbents have been able to adapt to these changes, new entrants and mid-range manufacturers face considerable challenges.
- Due to COVID-19, the demand for oxygen concentrators and medical ventilators has been rising quickly. As a result, oxygen and flow sensors for medical equipment have become a crucial component of how medical concentrators and ventilators operate.


Europe Gas Sensors Market Trends

Automotive Application to Grow at a Fast Rate


- As per the European Commission, passenger cars and vans ('light commercial vehicles') are responsible for around 12% and 2.5%, respectively, of total EU emissions of carbon dioxide (CO2), which is the main greenhouse gas. The popularity of gas sensors in the automobile sector is increasing as government pollution rules become more rigorous.
- In 2023, Germany produced the most passenger cars in Europe. Its production amounted to some 4.11 million passenger cars that year. Spain ranked second with almost 1.91 million passenger cars produced. Such countries caters to the major demand for the market.
- The entrance of pollutant gases through ventilation systems, pollutants entering through window apertures, a lack of fresh air intake resulting in low oxygen (02) concentrations, and toxic gases entering via redirected exhaust fumes all have a significant impact on the air quality in the car cabin. As a result, strict environmental and safety laws oblige all vehicle and transportation OEMs to offer gas sensor systems.
- Additionally, the usage of gas sensor and detector components per car is being enhanced by the migration of safety and comfort features from high-end sector vehicles to mid-range vehicles, owing to the rise of complex safety features and advanced driver assistance systems (ADAS).
- Improvements in the efficiency of combustion in a vehicle can result in reductions in the emission of harmful pollutants and increase fuel efficiency. Gas sensors have an important role to play in this process, since they can provide real-time feedback to the vehicular fuel and emissions management systems as well as reduce the discrepancy between emissions witnessed in factory tests and 'real world' scenarios.
- Leading automotive sensor companies like Bosch, Denso, and Infineon Technologies are making signficant investments into more technologically sophisticated, safer, and secure gas sensor-based products for a variety of applications.


United Kingdom to Occupy a Significant Share


- The UK Gas Analysis and Sensing Group (GASG) has been pivotal in promoting advancements in gas sensing technology since its establishment. It serves as a forum for professionals across academia, industry, and government to discuss innovations and share knowledge related to gas detection.
- Gas detection is heavily regulated in the UK, primarily governed by the Health and Safety Executive (HSE). The guidelines include compliance with workplace exposure limits (WELs) for various gases such as carbon monoxide (20 PPM over an 8-hour TWA) and hydrogen sulfide (5 PPM over an 8-hour TWA).
- Owing to the presence of many toxic and combustible gases, there is a growing focus on explosion prevention within hazardous locations in manufacturing and chemical industries. The monitoring of these hazardous areas can help achieve safer working environments. Moreover, many government and industry regulations necessitate workers to be limited to the exposure of toxic gases and fumes. Consequently, there is an increase in the use of electrochemical gas sensors, which provide improved sensitivity and selectivity for a broad range of toxic gases.
- Electrochemical sensors can measure oxygen levels down to the parts-per-million (ppm) level, which makes them a vital sensing technology for many different industries. Moreover, these sensors can be constructed differently depending on the application and, thus, provide tailored solutions to new emerging applications.
- However, most electrochemical sensors demonstrate some degree of cross-sensitivity, which refers to the response of the sensor to gases other than the target gas, generally as a result of greater chemical reactivity in the non-target gas than the target gas. As such, it is important to employ the use of filters and bias voltage during operations for minimizing the effect of cross-sensitivity on the accuracy of readings.
