Sustainability

Sustainability is embedded in our governance, decision-making, risk management and day-to-day operations.

Sustainability is core to how TransAlta operates and makes decisions

It shapes how we manage risk, allocate capital and deliver long-term value for our customers, communities and shareholders.

We focus on continuous improvement across material sustainability factors to mitigate risk and support long-term value creation. Our approach balances economic performance with environmental stewardship and responsible partnerships.
