How Can We Help You?
Environmental Managers of national companies often struggle to obtain emissions reports from their sites, to keep Atmospheric Emission Licenses (AEL’s) current, and to reduce emissions.
Yellow Tree can help by conducting compliant stack testing at all sites, consolidating this feedback for head office, keeping Atmospheric Emissions Licenses (AEL’s) up-to-date and recommending engineering solutions to reduce emissions.
Yellow Tree’s team of chemical engineers offer all the support required to ensure national compliance.
what our clients have said about us
Yellow Tree has engineering knowledge of the solutions to air quality issues as well as in-depth knowledge of the methods and equipment required to quantify emissions. They have both BSc Chemical and Mechanical Engineers in their employ which is beneficial to companies requiring engineering insight into both the testing and solutions. We are happy to recommend their services to others.”

Don’t get fined for non-compliance; engage a reputable stack testing company!
The Air Quality Legislation of South Africa makes provision for 10 years imprisonment or a fine of up to R 5 million. It is essential that companies comply with the legislation by having up-to-date Atmospheric Emissions Licenses (AEL’s) and by conducting compliant emissions testing. Yellow Tree can help.
Brand reputation
Corporate compliance extends beyond merely complying with the legislation. Responsible companies consider the impact of their operations on the environment, and are good citizens. Reputational damage can cost brands dearly. Yellow Tree can help companies build stronger brands through air quality compliance.
