We are making a sustainable difference
Our advanced emissions monitoring technologies, methods and expertise are applied across several industries worldwide - from oil and gas to agriculture.
Who we are
Founded in 1998, Explicit has made it its mission to deliver better, more reliable and cost-efficient concepts and technologies for measuring emissions essential to our climate and air quality.
The world is on a mission to reduce the impact of greenhouse gasses and air pollutants for a more sustainable future. However, the success of those efforts relies on the ability to credibly trace and measure harmful emissions. Without reliable emissions data, we will not know the true effectiveness of environmental initiatives, regulations and reduction strategies.

DFM measurements

Empowering actionable emission insights
Data specialists at heart, we have made it our priority to ensure the information we provide to our clients about emissions, is as reliable and actionable as possible. Our approach is anchored in solid science, validated methods, and proven technologies. 100 % application-driven, we select and integrate technologies depending on the measuring task at hand, always keeping our options open for innovations in sensors, platforms and methods that can advance our data goals.
History of Explicit
Explicit is founded
The first many years are focused exclusively on data acquisition systems and software development for some of the leading financial institutions in Denmark.
1998
First "sensodrone" was developed
A love of chemistry, software and model airplanes sets the company on a new path when CEO Jon Knudsen develops the first ‘sensodrone’ – a UAV designed to carry a gas sensor payload linked to an online data analytics platform.
The company receives its first funding from the Danish Ecoinnovation Fund (MUDP) to develop a mini sniffer and drone solution specifically aimed at surveying sulphur emissions from ships in response to tighter fuel controls in the maritime industry.
2013
Maritime emissions finalist
Explicit is recognized as a finalist for its maritime emissions innovation at the annual Ocean Exchange conference.
2014
Helicopter sniffer test
Explicit conducts its first scale test of the Explicit Mini Sniffer System in Dutch waters together with the Dutch authorities. This time, no drones are involved. Instead, the system is mounted on a manned helicopter. More than 300 ships are surveyed for sulphur compliance.
2016
Danish emissions contract
Explicit is awarded the first contract to survey sulphur emissions in Danish waters using crewed aircraft on behalf of the Danish Environmental Protection Agency. The company completes its strategic shift from financial software development to emissions monitoring services.
2017
EMSA drone monitoring
Explicit is part of the consortium awarded the first contract on behalf of the European Maritime Safety Agency (EMSA) to survey sulphur emissions using drones. The service deploys long-range (BVLOS) drones to monitor exhaust emissions from ships navigating through European waters. The service has been running ever since.
2018
Shift to GHG monitoring
COVID 19 hits. As the world is put on pause, the pandemic opens up room for new developments and Explicit shifts its focus from maritime to methane and other GHG emissions.
2020
German expansion
Explicit opens local representation in Germany and expands its engineering and research team.
2021
DFM Method launch
The DFM Method is born and the first successful offshore trials conducted in Danish sector. The method is a response to growing market demand for quantitative top-down surveys spurred by the Oil Gas Methane Partnership 2.0 and other regulations. Quantitative site level surveys are now a key component of the company’s strategy.
2022
DFM accreditation & global expansion
Explicit achieves ISO/IEC 17025 accreditation for the DFM Method, the first-ever accredited drone-based gas sensing technique.
The first DFM surveys are conducted outside Europe. The company is now active on three continents.
2023
Flare Efficiency & Australasia expansion
Explicit adds Flare Destruction Removal Efficiency to its survey offering and expands its ISO portfolio with ISO 9001 certification.
Explicit expands its local presence to Australia to service the Australasia region.
2024
Norway office & Equinor collaboration
Explicit opens local office in Norway collaborating with Equinor on drone-based methane surveys offshore as well as onshore.
2025

Patents and accreditations
Explicit holds several patents on monitoring methods and system design and have received international recognition for our solutions to monitor emissions.
Explicit is accreditated for testing in compliance with requirements in DS/EN ISO/IEC 17025:2017 by DANAK, and certified by FORCE Certification A/S to be compliant with the Quality Management System requirements of DS/EN ISO 9001:2015.
