Research and development

Opus seeks continuous improvement in its products and processes. In addition to providing emission control services throughout Europe, the company carries out internal research activities with a strategic vision.


Furthermore, Opus RSE is currently involved in several European research projects, summarised below.


The CONOX project is under a contract from the Federal Office for the Environment in Switzerland, BAFU (  The CONOX project is the outcome of a common European and US collaborative effort to analyse how large datasets from remote sensing measurements carried out in various locations and countries across Europe can be used as a complement to existing approaches to measure road vehicle emissions, in order to achieve a better understanding of the European issue of air pollution from road transport. 


The study focuses on NOx emissions from light-duty diesel vehicles, preferably passenger cars, corresponding to the Euro 4, 5 and 6 standards, since recent research has shown that these are key sources for NOX emissions in Europe. 


1 MILLION emission data records of real-driving conditions have been captured from remote sensing measurements in Spain, Sweden, Switzerland and United Kingdom. It is the largest database of remote sensing measurements in Europe and is helping the Scientific Community to understand the exhaust emissions problem in the continent.

Life Gystra

EU-funded project that seeks to validate and demonstrate the feasibility of a continuous traffic emissions monitoring program in Europe, thanks to improved remote sensing devices.


During this project, 3 RSDs will be continuously measuring traffic emissions in Madrid and Sofia for two years.


In Madrid, Spain, a "public model" is set. 2 RSDs will be measuring in different roads of Madrid urban area. The national traffic authority of Spain is involved in the program. This model will characterize the real-driving emissions of the city and will seek for irregularities in the fleet.


In Sofia, Bulgaria, a "private model" is going to be done. 1 RSD will be measuring in the entrance of a city bus station. The buses fleet will be continuously monitored, to find high-emitting buses, repair them and continue to monitor them afterwards to check the effectiveness of the repairs.


This continuous monitoring project is going to be very important, as it will allow us to understand the temporal evolution of real-driving emissions over a long period of time. In addition, the huge amount of data to be collected will serve to analyse extensively all the parameters and characteristics associated with traffic emission levels. The whole program will also be the first step to set-up long-term remote sensing monitoring programs in Europe.


The C-Roads Platform is a joint initiative of European Member States and road operators for testing and implementing C-ITS services in light of cross-border harmonisation and interoperability. 

Opus RSE is one of the partners of C-Roads Spain, where different pilots will test several traffic C-ITS services.  The objective is that authorities and road operators join together to harmonise the deployment activities of cooperative intelligent transport systems across Europe. RSD technology delivers extra information about the traffic different to more traditional data. Real-driving emissions data will be captured and transfered to the C-Roads dataservers.
