21 Years of Projects – Week 3: The 2005 Tembisa AQIA and a Growing Role in Environmental Authorisation

Introduction

This year marks 21 years of environmental project excellence by the Gondwana Group. As part of our celebration, we’re highlighting 21 projects over 21 weeks to showcase our journey and the value we continue to bring to clients across sectors.

Project 3 of 21: Tembisa Air Quality Impact Assessment (AQIA), 2005

In 2005, Gondwana conducted its first Air Quality Impact Assessment (AQIA) for a project in Tembisa, Gauteng. This was a turning point that launched our role as a specialist AQIA provider—supporting both private industry and other environmental consultants.

What is an AQIA?

An AQIA is a science-based study that:

• Estimates emissions from an existing or proposed activity,
• Uses dispersion modelling to simulate how pollutants spread in the surrounding environment,
• Predicts ground-level concentrations and assesses potential health or environmental risks.

These assessments are essential for:

• Environmental Impact Assessments (EIAs),
• Air emissions licensing, and
• Ensuring ongoing regulatory compliance.

Our Role in AQIAs Today

Since that first Tembisa project, Gondwana has completed dozens of AQIAs for:

• Mining operations
• Energy and manufacturing facilities
• Urban and peri-urban developments
• In partnership with leading consultancies and industry leaders

Our reputation is built on accurate data, defensible modelling, and practical recommendations tailored to South African regulatory contexts.
