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.

Our sustainability strategy

TransAlta’s commitment to responsible electricity production began more than a century ago with the development of hydro assets that continue to operate today.

We operate a diverse fleet of natural gas, hydro, wind, solar and battery storage facilities. This diversity enables us to provide reliable and affordable electricity while continuing to invest in non-emitting and lower-carbon opportunities.
