Greenhouse gases (GHGs) measurements for climate action

Start your sustainability journey with carbon dioxide measurements.

GHGs measurements are essential in the fight against climate change

Greenhouse gases (GHGs) measurements are crucial in combating climate change. Carbon dioxide (CO₂), which accounts for 60-70% of the warming effect from human activities, is the primary GHG driving climate change. Accurate CO₂ measurements are essential for understanding and mitigating its impact.

Scientists, researchers, industries, and policymakers use GHGs data to monitor human and industrial emissions, develop emission reduction strategies, and implement climate change mitigation measures.

As a leader in environmental measurement technologies, Vaisala supports global initiatives like the WMO Global Greenhouse Gas Watch (G3W) and the World Economic Forum Initiative - Net Zero Carbon Cities, aiding efforts to track and reduce emissions.

CARBOCAP® technology inside

Vaisala has decades of expertise in CO₂ measurements.

First launched in 1997, the Vaisala CARBOCAP sensor features a groundbreaking innovation — the micromachined, electrically tunable Fabry-Pérot Interferometer (FPI) filter for built-in reference measurement. This reliable and stable sensor delivers accurate measurements across a wide range of industries and applications, from building automation and safety to life sciences and ecological research.

We use a single-beam and dual-wavelength NDIR (non-dispersive infrared) technology for measuring CO₂ concentrations. The patented CARBOCAP technology is used in all our CO₂ sensors, incorporating a unique tunable band pass filter that we developed and manufacture in our state-of-the-art cleanroom.
