Climate change

Our commitment

As an energy infrastructure company, we recognize our role in the larger energy system, including the ongoing management of our own GHGs. We are committed to managing our GHG emissions, focusing on our GHG intensity and continuing to integrate climate considerations into our overall business strategy.

Examples of our commitment to managing emissions:

  • We have invested billions of dollars to date in emission-less energy sources, such as nuclear power.
  • We have publicly documented climate change-related activities for nearly 20 years.
  • We collaborate with industry and government partners to enhance the safety, efficiency and reliability of our construction and operations, and have played a key role in advancing environmental stewardship across the energy industry.

Environmental innovation: First-of-a-kind waste heat power generation facility in Alberta

TC Energy is developing a new project that will use the heat produced at one of our compressor stations in southern Alberta to generate electricity. Working in partnership with Siemens, the project will use supercritical carbon dioxide as the working fluid to capture waste heat from the gas-fired turbine and use it to generate emissions-free electricity that will be put into the electricity grid, resulting in greenhouse gas reductions of 44,000 tonnes per year, or the equivalent of taking more than 9,000 vehicles off the road.

Investing in a balanced energy future

Our commitment to transition to a more balanced energy future extends to our business development decisions.

We are actively participating in supporting the energy shift from coal-fired generation to natural gas and nuclear. We have invested billions in emission-less energy sources, accounting for one-half of the power we produce.

We are also playing a key role in Ontario's successful elimination of coal-fired power generation through our 48.5 percent ownership of the Bruce Power nuclear facility. In 2015, we entered into an agreement with the Ontario Independent Electricity System Operator to extend the life of the facility to 2064. This agreement ensures reliable and affordable emission-less power for Ontario communities for decades to come.

Climate change is at the forefront of environmental interests at TC Energy.


TC Energy has an internal, multi-disciplinary team that continuously refines the company's strategy for managing climate change risks and opportunities. This group is responsible for monitoring, assessing and communicating the climate change policy and regulatory context over the near, medium and long-term. Key business risks including climate change risks are provided to TC Energy’s Board at regular meetings and the Governance Committee, which oversees the company’s approach to risk.

TC Energy operates under a low-risk and enduring business model that maximizes the full-life value of our long-life assets and commercial positions through all points in the business cycle. While renewables are the fastest growing form of new power generation, respected authorities such as the International Energy Agency forecast that oil and natural gas will continue to be dominant energy sources and a vital part of the energy mix for decades to come. Our investment in balanced and sustainable energy systems, our current asset portfolio and our future growth plans all reflect the long-term supply and demand forecasts for all forms of energy.

TC Energy understands that shareholders and other stakeholders want more information on how the company is addressing climate change and associated risks.  In response to a shareholder proposal received in late 2017, TC Energy committed to providing additional disclosure on how the company is assessing long-term risks and opportunities in relation to climate change and the current transition to a low-carbon economy. In 2019, we released our inaugural Sustainability and Climate Change report.

As the tools available to assess the risks and opportunities associated with climate change improve, we are utilizing them in order to increase the rigour of our assessment, as a key input into our strategic planning process. TC Energy is committed to continually improve our disclosure and as such we are planning to employ the IHS 2°C Scenario in 2018 when updating our business strategy.
