HEAT is set to install more EDAR systems in Germany later in the year.

On September 10, 2019, a press conference was held at the Paris Mayor’s Office where the International Council on Clean Transportation (ICCT) along with the FIA Foundation released the initial findings and statistics from EDAR’s successful remote sensing data collection campaign in Paris during the Summer of 2018. This campaign was a part of The Real Urban Emissions Initiative (TRUE); an initiative established in cooperation with C40 Cities, the Global New Car Assessment Programme (Global NCAP), and Transport and Environment (T&E). During this campaign, HEAT’s EDAR system measured over 180,000 vehicles in a few short weeks, which, as stated by the TRUE Initiative, “is the largest European dataset from any remote sensing campaign lasting less than a month.” Additionally, the ICCT released a comprehensive white paper and fact sheets that detail the study’s unique findings.

In June 2019, Hager Environmental & Atmospheric Technologies (HEAT) performed a remote sensing emissions testing campaign in the Flanders region of Belgium at five (5) locations over a month in the cities of Ghent, Antwerp, Bruges, and Erpe-Mere. This measurement campaign, performed over two weeks, resulted in 210,000 valid measurements, of which over 50,000 were trucks and lorries. HEAT conducted this campaign in cooperation with the Flemish Government Environment Department, the Free University of Brussels (VUB), and the Dutch Organization for Applied Natural Science (TNO).

EDAR made history!

Belgium is the first country in the history of remote sensing to set up a remote sensing system on a high-speed, multi-lane highway. During the measurement campaign, EDAR deployed on a bridge overlooking the busy E40 motorway. The speed limit on the E40 is 120kmh, and EDAR detected, with high accuracy, vehicles traveling up to 170kmh. (A video of the bridge installation is available at this link.) The unique installation proved that the EDAR system performs just as well in high-speed conditions as it does on slower city roads. In addition to the groundbreaking performance on the high-speed highway, HEAT also contributed to an extraordinarily successful Anti-Tampering Campaign, in which heavy-duty trucks were tested in real-time on-road by EDAR. During testing, if the EDAR system detected tampering based on the truck's emissions on-road, the truck was pulled over for further inspection. This extremely successful campaign using EDAR increased the Flemish Government’s success rate from 9% to over 86%. The entire collected dataset is currently under analysis for a report expected to be released later in 2020.

In 2023, HEAT continuously monitored vehicle emissions using its proprietary technology, EDAR, in Scotland’s four major cities of Aberdeen, Dundee, Edinburgh, and Glasgow on city roadways in and out of the Low Emission Zones, including trunk roads. The results of Phase II helped inform future air-quality policy and investigated ways to reduce air-pollution levels by mitigating the misuse of emission- abatement equipment and controls.

The comprehensive turnkey service in 2023 was the Phase II continuation of a three-year commitment to assess the real-world nitrogen oxide (NOx) emissions from all vehicle types, including passenger cars, taxis, and private hires in identified zones prior to the launch of four low-emission zones (LEZs) in the city centers of each of the four major metropolitan areas.

​Scotland has the largest collection of remote sensing vehicle-emission records in the United Kingdom and continental Europe, totaling more than 1.5 million valid vehicle emissions records compiled during four months of study over the three-year contract in the country.

“Remote sensing provides insight into real-world emissions of diesel and petrol vehicles in the urban environment, detecting emissions that diverge from the type approval limit and typical levels. In improving our understanding of vehicle emissions and developing effective solutions, we can support the delivery of policies to improve air quality and benefit the health of people in Scotland,” said Derek McCreadie, Air Quality and Environment Senior Advisor of Transport Scotland.

Transport Scotland’s 2022 collaboration with HEAT proved to be the most extensive remote sensing testing campaign in Europe to that point. This first-of-its-kind project collected real-world emissions in Edinburgh, Glasgow, Dundee, and Aberdeen in Scotland over a three-year period to support evidence-based transportation policies at the local and national level. The project, in part, was initiated to support the Scottish Government's commitment to introduce LEZs into the country’s most populated cities. LEZs set an environmental limit on certain road spaces and restrict entry of the most polluting vehicles, with the aim of improving air quality in Scotland’s city centers. Scotland launched LEZs in the cities involved in the study during the summer of 2023.

In Spring 2022, EDAR remote sensing was conducted in all four Scottish cities simultaneously. More than 480,000 real-world emissions were collected during the month of observation. An initial phase of study was conducted in October 2021.

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 calls for the collection of 300,000 valid emissions records to be collected on-road from Scotland's trunk roads. The contract required the first installation must be completed by August 31st, 2019. HEAT mobilized quickly once awarded at the beginning of August and accomplished this task on time to complete Phase I, Part I of the program. In the second part of Phase I, the agreement required the installation of EDAR systems on gantries overlooking high-speed highways by February 2020 to complete data collection to meet the goal number of 300,000 valid remote sensing records from Scotland's trunk roads. The data collection portion of Phase I, Part II, 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.

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 the 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 aid in tackling 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.

Dr. Pierre Bonnel, a senior researcher in the Sustainable Transport Unit of the European Commission Joint Research Centre (JRC) presented to European Parliament in September 2017 about the findings made in a blind validation study performed with EDAR at the Joint Research Centre in Ispra, Italy. It was determined during this evaluation that EDAR is able to distinguish Euro 0 to Euro 6 emissions standards within a given vehicle technology including diesel, gasoline, LPG, and with or without diesel particulate filters (DPF). Excellent correlations were made with EDAR under real-world conditions. The standard error between EDAR and the competing RSD technology shows that EDAR is significantly more accurate; especially with detecting low amounts of the test gases.

In February 2016, HEAT completed a month-long trial in the United Kingdom with deployments in Birmingham and London. This trial was performed in conjunction with the Department for Transport, Kings College and the University of Leeds to deploy EDAR on highly travelled roads in the United Kingdom to detect and quantify CO, NO, NO2, and PM from the largely diesel fleet. The collection and analysis were completed in 2016, which resulted in a peer reviewed published article and multiple presentations worldwide.
