Since 2017, HEAT has been providing world-class remote sensing services to Scotland and its municipalities. EDAR is an innovative solution aiding Scotland in meeting its air quality goals as well as bringing its Low Emission Zones to the forefront by leading the way with the most advanced technology available on the market today.
The Vehicle Emissions Partnership (VEP) and the Scottish Government funded a pilot deployment of the EDAR system in Scotland in March 2017 as part of their “Switch off and Breathe” campaign. Testing took place in three locations with one EDAR system over a month in the Glasgow and Edinburgh areas during the winter, exposing EDAR to challenging weather conditions such as snow, rain, and hail, but EDAR was able to successfully collect data despite adverse conditions.
Using a single unit, EDAR collected 140,000 valid reads, which provided substantial amounts of information for local municipalities to perform fleet analysis and modeling while increasing public awareness of the effects of on-road emissions. This data will also help contribute to making plans to tackle issues associated with vehicle emissions and to assist in the creation of sound public policy for Low Emission Zones. During this installation, EDAR collected gas data from each vehicle, including CO2, NO, NO2, and PM.
EDAR successfully captured emissions from all vehicle types that traveled underneath the unit, including heavy-duty diesels, and demonstrated its ability to run unmanned, 24/7, under demanding weather conditions, thus further proving that EDAR operates effectively and efficiently in any season.

EDAR Deployed in Scotland during Phase I, Part II of the LEZ Pilot
In August 2019, HEAT was awarded a contract by Transport Scotland to implement Phase I of a remote sensing Low Emission Zone pilot program. The contract called for the collection of 300,000 valid emissions records to be collected on Scotland's trunk roads. The contract required the first installation to be completed by August 31st, 2019. HEAT mobilized quickly once awarded the contract at the beginning of August and accomplished this task on time to complete Phase I, Part I of the program.
In Phase I, Part II, the agreement required the installation of EDAR systems on gantries overlooking high-speed highways by February 2020 to complete the data collection and meet the goal number of 300,000 valid remote sensing records from Scotland's trunk roads. During the data collection portion of Phase I, Part II, EDAR collected over 75 percent of the required 300,000 records during Scotland’s most challenging winter weather, in a three-week time period, which ended at the end of February 2020. The purpose of this program is to trial the use of remote sensing for policing and monitoring Low Emission Zones in Scotland. The measurements from this pilot and the expertise from HEAT’s remote sensing specialists will support Transport Scotland in the implementation of a full-scale program as part of the country's air quality scheme.
