Our Climate Change Plan

We're proud to release 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.


Ontario Power Generation believes climate change is not the future, it’s the present, and its consequences are already affecting the lives of Ontarians. Because it’s not just an environmental crisis, it’s also an economic one...

So the steps we take to address climate change today must improve the lives of everyone and make communities stronger and more resilient. We will create new jobs and nurture new industries to make life better, not just for future generations but for current generations as well.

At OPG, we’re proud to have delivered the world’s single largest climate change action to date when we stopped burning coal. But there’s so much more we can do.

That’s why I’m pleased to introduce OPG’s new climate change plan. It’s the product of work by teams from across our company. As part of our plan, we’re setting ambitious goals that will guide our promise to be a catalyst for efficient, economy-wide decarbonization, mobilizing our expertise, suppliers, and industry partners to create a cleaner environment and more prosperous, resilient communities in Ontario and beyond.

Our goals won’t be easy to achieve. The way forward won’t always be clear. But we won’t let that lack of perfect clarity stop us from taking action now. And while this is the first time you’re hearing about our new climate plan, it will not be the last. You can expect regular updates on our progress.

Today’s biggest energy questions will be answered right here. We hope to make our province proud as we bring our made-in-Ontario experience, our ingenuity, and our commitment, to the world. Together, we will create a brighter tomorrow.

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.

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.

Guiding principles

As we strive to be the catalyst that enables the transformation to clean economies, we will do so in the most efficient and responsible way possible, always respecting the best interests of the people we serve. These guiding principles are our commitment to you as we chart a new path forward.

While our goals are firm, the way we reach them will evolve over time. Our plan is designed to adapt to new technologies and changing policies.

We have tried throughout this document to avoid technical jargon to give you plain facts. We will update you on our progress continuously in the years ahead.

We are guided by the scientific consensus on climate change. Our decisions will be based on the best available evidence on impacts, solutions, and measurement.

We strive to be a low-cost generator and we will ensure customers’ interests are top-of-mind as we work to achieve our goals.

Preserving openness, transparency and trust will underscore our ongoing commitment to growing long-term, mutually beneficial working relationships with indigenous communities near our current and future operations.

These days, companies are being held to account by investors, governments, and the public for their progress in addressing climate change. We welcome the scrutiny.

As one of North America’s leading clean generators, there is so much we can do to make an impact. We have an obligation to contribute to the full extent of our capacities.
