About Us
​
At Terrama, we believe that competency building is the foundation of real sustainability transformation. Sustainability is not just about doing what’s right—it’s about making it work. Our founders, industry experts in sustainability, finance, and education, saw firsthand how businesses and professionals struggled to bridge the gap between theory and execution.
​
This inspired us to create a structured, competency-driven approach to sustainability education—one that ensures individuals and organisations gain the knowledge, skills, and mindset needed to embed sustainability into strategy and operations while taking concrete action.
​
​At Terrama, we don’t just teach sustainability—we equip professionals and businesses to implement it effectively through expert-led training, hands-on learning, and industry collaborations.
