The Global Carbon Pricing Challenge

Countries around the world are taking action to reduce greenhouse gas emissions and fight climate change. More and more countries are pricing carbon pollution to cut emissions at low cost while also spurring clean innovation. According to the World Bank, there are currently 68 carbon-pricing initiatives in place around the world in 2022.

Carbon pricing is most effective when more countries adopt it – broader coverage means more opportunities to find clean solutions. Through international cooperation, countries can send consistent signals to investors that it cannot be free to pollute. Raising climate ambition together, recognizing common but differentiated responsibilities, helps to ensure that producing emissions elsewhere does not equate with avoiding carbon costs.

Canada is calling on all countries to adopt carbon pricing as a central part of their climate strategies, toward a collective goal of covering 60 percent of global emissions by 2030.

To achieve this goal, Canada has launched the Global Carbon Pricing Challenge. This partnership of carbon pricing Champions from around the world aims to expand the use of carbon pricing by strengthening existing systems and supporting emerging ones. The Challenge also creates a forum for dialogue and coordination to make pricing systems more effective and compatible and to support other countries in adopting carbon pricing.

Latest developments


At the 2021 United Nations Climate Change Conference (COP26) in Glasgow, Canada co-hosted an event with the Carbon Pricing Leadership Coalition. At the event, the Prime Minister issued a challenge to all countries to triple the global coverage of carbon pricing from around 20 percent of global emissions today to 60 percent by 2030 as an important step toward advancing global carbon pricing and achieving net-zero by 2050.


The Prime Minister reiterated the Global Carbon Pricing Challenge in a commentary (English only) in the Carbon Pricing Leadership Coalition's 2022 Annual Leadership Report, calling on countries around the world to come forward with new carbon pricing commitments at COP27 in Egypt.

In June 2022, Canada and Chile made a joint statement in support of the Global Carbon Pricing Challenge and committed to convening a high-level event at COP27 to showcase the role of carbon pricing in the global response to climate change.

In November 2022, Prime Minister Rishi Sunak of the United Kingdom confirmed that the UK would be a partner to the Global Carbon Pricing Challenge.

How carbon pricing works

The many costs of climate change—whether financial, environmental, or social—can only be mitigated by tackling the root cause and reducing greenhouse gas emissions on a global scale. Carbon pricing is widely recognized as one of the most efficient tools to reduce greenhouse gas emissions while also driving innovation. It is a broad and flexible policy to drive climate action, complementing other regulations and public investments that target specific sectors or actions.

In simple terms, carbon pricing works because there is a financial incentive for people and businesses to pollute less. Carbon pricing is transparent, and sends a clear signal that carbon-intensive products are costly. Industry and households can decide how best to cut their emissions at the lowest cost, and are encouraged to adopt these changes or solutions into their business operations and lifestyles.

Carbon pricing holds large-emitters accountable, since the more they pollute, the more it will cost. Capturing the cost of carbon pollution on each unit of emissions spurs the development of clean technologies and services, and fosters innovation in industry.

The design of carbon pricing systems varies, with the choice of instrument based on the local context:

While everyone has a vital role to play in reducing emissions, countries around the world are working hard to expand their economies and improve the lives of their citizens. Revenues from carbon pricing can finance sustainable development and support vulnerable sectors and communities that feel the impact of climate change the most.

Canada's leadership on carbon pricing

Carbon pricing in Canada has been in place in every jurisdiction since 2019. Canada's approach is flexible: any province or territory can design its own pricing system tailored to local needs, or it can choose the federal pricing system. The federal government sets minimum national stringency standards (the federal "benchmark") that all systems must meet to ensure they are comparable and effective in reducing greenhouse gas emissions, including a common scope and a minimum carbon price trajectory that will reach $170/tCO2e by 2030.

Canada uses proceeds from carbon pricing to directly support households in a way that benefits low-income and vulnerable communities the most. Proceeds are also used to support small businesses, Indigenous organizations, and communities through climate action programs. Returning proceeds helps make carbon pricing affordable, and enables households and businesses to make investments to further reduce emissions. Carbon pricing systems across the country are designed to decarbonize industries while also supporting their competitiveness and limiting the risk of carbon leakage.
