Building a brighter tomorrow.
Ontario Power Generation (OPG) believes climate change is not just in the future, it’s in the present. Its consequences are already affecting the lives of Ontarians. Its not just an environmental crisis, it’s also an economic one.
In 2020, we released our first-ever Climate Change Plan. It includes ambitious goals that will guide our promise to be a catalyst for efficient, economy-wide decarbonization and economic renewal, while protecting the environment.

Our climate change goals.
Our climate change plan started with a simple question: what can we do to make tomorrow better? The answer, it turns out, is quite a lot. Along with setting an ambitious goal for our company, we’re looking beyond our walls to help markets where we operate achieve their goals.

For decades, OPG’s world-class workforce has quietly led the charge, devising the blueprint for a carbon-free future. With our coal closure, conversion of the Atikokan Generating Station to renewable biomass, the Darlington Nuclear Refurbishment, the expansion of our hydro generating assets, and through clean power partnerships like the Gull Bay micro grid and the Nanticoke Solar facility, we are already one of the most diverse, experienced generators in the world but we’re ready to do more.
Tackling climate change will take a combination of electricity generating technologies and innovative solutions. Most importantly, it will take the full commitment of societies around the globe. We’re determined to do our part.
Positioned to lead.
Ontario’s electricity system and its generating technology is constantly evolving. In 2005, before we closed our coal fleet, the electricity sector accounted for 17% of Ontario’s carbon emissions. Fast forward to 2016, two years after the phasing out of coal, the electricity sector accounted for only 2% of Ontario’s total emissions. In fact, compared to other progressive global jurisdictions from a carbon intensity perspective, Ontario ranks among the best.
The transportation sector is now the province’s largest source of carbon emissions at more than 30%. Powering cars, trucks, trains, boats and buses with clean electricity, rather than gas or diesel, will make a significant impact to reducing carbon emissions in Ontario. The more of the economy we can get running on electricity, the lower our carbon emissions will be overall. As Ontario’s largest power generator and clean technology innovator, OPG is well positioned to lead the drive for decarbonization while balancing economic and environmental benefits, and Ontario’s electricity needs.

What does 'net-zero' mean?
‘Net-zero’ refers to achieving an overall balance between direct carbon emissions produced and carbon emissions taken out of the atmosphere.
