Carbon Dioxide Monitoring Equipment Global Market Report 2025

The carbon dioxide monitoring equipment market size has grown rapidly in recent years. It will grow from $3.52 billion in 2024 to $3.92 billion in 2025 at a compound annual growth rate (CAGR) of 11.4%. Growth during the historic period can be linked to increasing emphasis on workplace safety standards, rising concerns about greenhouse gas emissions, the growing implementation of ventilation control systems, the need for greater accuracy in air quality monitoring, and expanded use of carbon dioxide sensors in industrial operations.

The carbon dioxide monitoring equipment market size is expected to see rapid growth in the next few years. It will grow to $5.96 billion in 2029 at a compound annual growth rate (CAGR) of 11%. Growth in the forecast period can be attributed to heightened awareness of indoor air quality and safety, increasing adoption of smart building technologies, stricter industrial emission control regulations, rising demand for effective environmental monitoring solutions, and growing utilization of carbon dioxide sensors in healthcare and food sectors. Key trends anticipated in the forecast period include improvements in sensor accuracy and miniaturization, the development of smart and connected monitoring platforms, innovations in energy-efficient and wireless designs, advancements in integration with building automation systems, and the emergence of portable and wearable carbon dioxide monitoring devices.

The rising environmental concerns are expected to drive the growth of the carbon dioxide monitoring equipment market in the coming years. Environmental concerns refer to issues caused by human or natural activities that negatively impact air, water, soil, ecosystems, and the overall sustainability of the planet. These concerns are intensifying due to population growth, which increases resource demand, generates more waste, and puts additional strain on ecosystems. Carbon dioxide monitoring equipment addresses these concerns by measuring and tracking CO₂ levels in the air or industrial processes, enabling timely actions to reduce emissions, improve air quality, and ensure compliance with environmental regulations. For example, in December 2023, the School of Sustainability at Stanford University, a US-based university, reported that global carbon dioxide emissions were expected to exceed 40 billion tons in 2023, including nearly 37 billion tons from fossil fuels, representing a 1.1% increase compared to 2022 levels. Therefore, rising environmental concerns are driving the growth of the carbon dioxide monitoring equipment market.

Key companies in the carbon dioxide monitoring equipment market are focusing on developing advanced products, such as photovoltaic CO₂ monitors, to enhance detection accuracy, energy efficiency, and real-time monitoring capabilities. Advanced photovoltaic CO₂ monitors use light-based photovoltaic technology to accurately detect CO₂ levels with high sensitivity and low power consumption. For instance, in October 2024, Reef Technologies, a US-based digital solutions company, launched AIR-sense-IQ, an advanced photovoltaic CO₂ monitor powered by Epishine’s printed organic indoor solar cells. This device continuously monitors indoor carbon dioxide levels without the need for external power or battery replacements by harvesting energy from indoor lighting, making it highly efficient and maintenance-free. AIR-sense-IQ alerts users when CO₂ levels rise, promoting optimal air quality and comfort, particularly in office environments.

In October 2024, ABB Ltd., a Switzerland-based technology company, acquired the Födisch Group for an undisclosed amount. Through this acquisition, ABB Ltd. aims to expand and strengthen its portfolio in continuous emission monitoring systems (CEMS) and advanced measurement technologies, improving its ability to help industries tackle complex environmental and sustainability challenges worldwide. Födisch Group is a Germany-based manufacturer of carbon dioxide monitoring equipment.

Note that the outlook for this market is being affected by rapid changes in trade relations and tariffs globally. The report will be updated prior to delivery to reflect the latest status, including revised forecasts and quantified impact analysis. The report’s Recommendations and Conclusions sections will be updated to give strategies for entities dealing with the fast-moving international environment.

The rapid rise in U.S. tariffs and the subsequent trade frictions in spring 2025 are having a major impact on the electrical and electronics sector, with semiconductors, display panels, and rare-earth metals (essential for batteries and motors) subject to steep duties. Consumer electronics brands face profit erosion, as competitive markets limit their ability to pass costs to buyers. Industrial electronics manufacturers, meanwhile, grapple with delayed projects due to shortages of tariff-impacted components like printed circuit boards. Companies are responding by relocating assembly to tariff-exempt countries, increasing inventory buffers, and redesigning products to reduce dependency on restricted materials.
