Bettair in Belém for COP30: Air quality monitoring in the heart of the Amazon

Challenge

COP30, held in Belém (Pará, Brazil), represented a unique and critical opportunity: to conduct robust environmental measurements in the middle of the Amazon rainforest during a global climate summit. A solution was needed that could monitor pollutant gases, atmospheric particles, and meteorological variables in real time, in a tropical environment with difficult access and high humidity. In addition, it was vital to provide data to world leaders and citizens to reinforce climate decisions with tangible scientific evidence.

Solution

Bettair deployed two air quality stations during COP30 in Belém, in the state of Pará, Brazil. Through the Guamá Foundation and Bettair’s representative in Brazil, Almont do Brasil, these stations record gases such as NO₂, NO, O₃, SO₂, as well as PM1, PM 2.5, and PM 10 particles and weather conditions (temperature, humidity, pressure, and noise) in real time. All data generated is sent to a secure cloud platform that allows visualization, automatic alerts, and analysis for researchers and climate authorities, facilitating informed decision-making on environmental risks.

At a glance

– Hybrid network: 8 AQMS + 10 Bettair nodes.
– LEZ compliant as of January 2025.
– Meets CEN/TS 17660-1:2021 standards for indicative accuracy of gas monitoring.

Outcomes

0

Bettair is generating a continuous, high-resolution environmental database during COP30, providing key evidence to understand atmospheric emissions in the Amazon at a moment of global significance.

0

Real-time alerts and visualizations allow organizers and authorities to respond swiftly to pollution variations, reinforcing operational climate management during the summit and demonstrating the technology’s effectiveness.

The project leaves a scientific and technological legacy: a scalable platform that can be used after the summit for permanent monitoring and to support conservation and public health policies.

“…Our goal is to build a solid foundation, understand the environmental variability of the region and support decision making, both in internal planning for PCT Guamá and in support of environmental protection, urban resilience and civil defense policies. The experience has been very interesting, since the data collected already allows us to visualize patterns, identify variations in air quality and plan environmental actions in a more assertive way. In addition, the use of these sensors in the Amazon reinforces the importance of including the region in environmental monitoring initiatives of scientific and social relevance.”
