Emissions Sampling Services

We conduct emissions testing on combustion and process stacks in accordance with the South African Legislation and United States EPA methods. We also conduct Fenceline Monitoring, and Leak Detection and Repair (LDAR) Monitoring. We love what we do!

Air Quality Consulting

We can help you obtain your Atmospheric Emissions License (AEL), write an Annual Report, perform a Dispersion Model, calculate your Greenhouse Gas Emissions and Carbon Footprint, submit your NAEIS, calculate your Carbon Tax, develop a Pollution Prevention Plan, train your team, and build a relationship of trust with your Air Quality Officer. We are here to help!

How Can We Help You?

Environmental Managers often doubt the accuracy of emissions reports, struggle to keep Atmospheric Emission Licenses (AEL’s) current, and don’t know how to reduce their emissions.

Yellow Tree can help by conducting accurate and compliant stack testing at all sites, 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.

Stack Tests Client in South Africa

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.
