The world is on a mission to reduce greenhouse gas emissions for a more sustainable future. However, the success of these efforts relies on the ability to credibly measure such emissions. As the famous mathematician Lord Kelvin said, “If you cannot measure it, you cannot improve it.”
Without reliable data, we cannot assess the true effectiveness of environmental initiatives, regulations, and reduction strategies. This is where Explicit steps in.
We are data specialists at heart. Our approach is anchored in solid science, validated methods, and proven drone-based technologies. Here are some of the best practices we have developed over a decade of experience in emissions monitoring:
Transparent methodology
At Explicit, we rely entirely on measured data, not models or black-box calculations. We measure every parameter essential to calculating the mass flux rate. Gas and wind speeds are calculated directly from drone flights, and emissions are summed across each flux wall. Our method ensures high accuracy and credibility for regulatory compliance and environmental reporting.
Advanced multi-sensor technology
Our payload is built with multiple sensors for methane (CH₄), carbon dioxide (CO₂), wind, temperature, pressure, and humidity. This allows us to measure gas quantities, characterise sources, and assess flare and engine efficiency in a single flight. Our multi-sensor approach makes drone-based emissions monitoring not only effective and efficient, but also enables distinction between different sources for subsequent reconciliation.
Simple and safe operations
Everything is contained in a single pelicase, including tools, spares, and checklists (no batteries needed!) Setup is plug-and-play and takes just 15 minutes. A built-in ATEX warning system ensures safety in all operational environments, making our on-site emissions measurements fast, reliable, and safe.
Real-time reporting
Data is available in real time directly on the pilot’s controller, along with a quality score to ensure the validity of collected datasets. This enables immediate course corrections in the field if needed. Once the flight is complete, data uploads automatically to the Explicit Emissions Lab (E-Lab). ISO-accredited, quality-controlled reports are issued within 24-48 hours, and results can also be integrated into the client’s 3D site models for further analysis.
High-quality standards
Explicit is an ISO 17025-accredited laboratory for the Drone Flux Measurement (DFM) Method and ISO 9001-certified. Its accuracy has been independently validated at leading industry test sites, including METEC and TADI, ensuring reliable surveys for every client. With its high precision and quality, the DFM Method is trusted globally for emissions measurement across onshore and offshore operations.
