Yellow Tree

Yellow Tree is a team of engineers and scientists that specialize in stack emissions sampling and air quality consulting. We are passionate about the environment, accurate emissions results and great service.

When we conduct stack sampling, we take time to understand our clients’ processes. After conducting the testing we write a report and deliver a presentation, to help our client understand their results in the context of the South African Air Quality legislation and to help the client implement solutions to reduce their air pollution.

We conduct stack sampling on boiler and combustion stacks and on a range of industrial processes in accordance with the National Environmental Management: Air Quality Act (NEMAQA).

Our consultants can advise you on Section 21 and 23 of NEMAQA, Atmospheric Emissions License (AEL) Applications, NAEIS submissions, Annual Reporting, Green House Gas (GHG) reporting, Carbon Tax reporting, Leak Detection and Repair (LDAR) and Leak Detection Monitoring (LDM).

Most importantly, we absolutely love serving the environment and our clients.

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.
