The CPA is a member of the UNFCCC Parliamentary Group, which facilitates the engagement of Parliamentarians and parliamentary networks at UNFCCC meetings and COPs. The Group, led by GLOBE International, provides administrative, information and coordination support to engage cross-party legislators at these major international meetings.

The Group was established in September 2021. GLOBE International is the UNFCCC Focal Point for the Parliamentary Group. The other founding members are:

• Commonwealth Parliamentary Association
• Climate Parliament
• InterPares / International IDEA
• ParlAmericas
• Westminster Foundation for Democracy

Membership of the Parliamentary Group is open to Parliamentarians, parliamentary networks or organisations seeking to advance the aims of the UNFCCC and implementation of the Paris Agreement. GLOBE International has published a range of resources to support parliamentary engagement with COP26, including webinars and a regular newsletter.

The CPA Parliamentary Academy offers an online course on the basics of climate change and how it impacts small jurisdictions in particular.

The course focuses on the science of climate change, disaster risk management and the importance of international frameworks. In addition, it looks at how to mitigate against and adapt to the effects of climate change as well how to engage with the local community on climate-related issues.
