Our leadership

We are the world leaders in remote sensing technology applied to road traffic and all its associated applications. We carry out traffic monitoring programs in combination with Periodical Technical Inspections, we operate very sucessfull programs that identify the cleanest vehicles to reward their owners, we lead pioneering research and technological development projects, we coordinate multi-sector working groups and we work together with legislators and legal authorities to implement remote sensing in their national or local jurisdiction.

Leading technology

Our technology is the most widely used in the world for remotely measuring road traffic emissions. We are the only company in the world with an ISO-17025 accreditation for this activity. Our technology continues to evolve, with improvements in detection capabilities, accuracy, ease of use and adaptation to modern cities. Our systems can be used in many ways, from portable and mobile systems that can be deployed in a few minutes, to fixed systems that can be integrated into the road infrastructure. Our systems are connected to the cloud and have 5G capabilities. We are making groundbreaking developments in this technology, applying cutting-edge engineering science, to improve its capabilities in the coming decades.

Leading regulations and policies

Since the 1990s, Opus has led the way in regulating our technology around the world so that it can be used under the specific regulations of each country. Our methodology of control, calibration and auditing is a world reference, which has allowed the RSD to be introduced into the national regulations of different countries.


Some key historical milestones:

  • 1990s: California Bureau of Automotive Repair (BAR) developed the first industry performance specification for RSDs.
  • 1998: US Environmental Protection Agency (EPA) defines the first guidelines to screen vehicles with remote sensing: "Program User Guide for Interim Vehicle Clean Screening Credit Utility" (EPA420-P-98-007).
  • 2000s: Colorado’s Department of Public Health and Environment (CDPHE) started evaluating each unit for compliance with its specifications.
  • 2002: US Environmental Protection Agency (EPA) defines a guidance on the "Use of Remote Sensing for Evaluation of I/M Program Performance" (EPA420-B-02-001).
  • 2003: Colorado's RapidScreen program, which continues in operation today, becomes the first large-scale program to control vehicles' emissions using Opus Remote Sensing monitoring.
  • 2010: European Commission Directive 2010/47/EU of 5 July 2010 allows police authorities to carry out technical emissions inspections of commercial vehicles on the road based on the alert given by an RSD
  • 2013: The Spanish Accreditation Agency (ENAC) grants Opus RSE the ISO-17025 certification for the remote measurement of motor exhaust emissions with Opus RSDs.
  • 2014: The Pollutant Emissions Unit of the Spanish Ministry of the Environment (CIEMAT) evaluates Opus' RSD technology and sets some specific emission limits to identify high-emitters on public roads in Spain.
  • 2014: The Spanish Ministry of the Environment publishes a draft regulation to regulate the real-driving exhaust emission emitted by the vehicles circulating on public roads.
  • 2019: European Commission's’ Joint Research Center validates Opus RSD.

Supporting our partners

We are obsessed with offering the best solutions and services to our clients. Thanks to this philosophy, the degree of satisfaction we achieve in every project is enormous. We are continuously improving our technology, creating new customized digital services for and integrating various technologies to offer products of greater value.


On the other hand, we are convinced that achieving global success and a radical transforming the urban mobility cannot be achieved alone. That is why we have partners all over the planet, who take our technology and exploit it in their own territories, thus creating a technological and operational ecosystem on a large scale.
