How to join the Net-Zero Challenge

Who can join

All companies operating in Canada, including domestic and international companies and corporations and small- and medium-sized enterprises, can join the Net-Zero Challenge. Industry associations can also join the Challenge and can encourage their members to participate and support them in the development of their net-zero plans.

How to join

Companies can join the Challenge at any time. The first step to join the Challenge is for a company to identify its participation stream and sign our commitment letter indicating that it commits to achieving net-zero emissions by 2050 and that it will fulfill the requirements of the Challenge.

There are three different Commitment Letters.

Please send your signed commitment letter to

Shortly after submitting the Commitment Letter, companies can expect the Net-Zero Challenge to provide confirmation that they received the completed Commitment Letter and to provide information on next steps.

Participation streams

Scope of emissions

Scope of emissions is a way of categorizing and defining the direct and indirect emissions that an organization produces.

  • Scope 1 emissions covers a company's direct emissions, principally resulting from activities undertaken by the company.
  • Scope 2 emissions covers a company's indirect emissions from electricity, heating/cooling, or steam that a company purchases for its own use.
  • Scope 3 emissions covers a company's indirect emissions that are not included in scope 1 or 2.

There are different requirements for each participation stream in the Net-Zero Challenge.

All participants must include scope 1 and 2 emissions, while there are different requirements for scope 3 emissions, as shown in Table 1.

Table 1: Key Differences between Participation Stream Requirements (Scope 3)
Stream 1 Encouraged to include relevant scope 3 emissions categories
Stream 2 Must include scope 3 emissions category 15 (investments from Greenhouse Gas Protocol) and, if applicable, lending portfolio emissions
Stream 3 Must include the single most relevant scope 3 emissions category
SMEs Encouraged to include relevant scope 3 emissions categories

Minimum requirements

By signing a commitment letter companies agree to:

  1. Set a net-zero emissions target for 2050 or earlier;
