Join Us

With close to 100 signatories representing 34% of GDP, the Climate Leaders Coalition is a CEO-led community of like-minded businesses leading the way to a zero carbon and climate resilient future.

Joining the Coalition is a credible way of demonstrating your organisation’s climate leadership.

In order to join, you must be meeting the minimum requirements set out in our Statement of Ambition:

  • Measuring your emissions and reporting them publicly;
  • Adopting short-term gross absolute science aligned targets for scope 1 and 2 emissions to support the delivery of substantial reductions needed to limit future warming to 1.5 degrees Celsius;
  • Assessing climate change risks and publicly disclosing them; and
  • Proactively enabling employees and suppliers to reduce their emissions.

All signatories must be meeting the Statement of Ambition in full by September 2025 at the latest.


Signatory Benefits

Networking opportunities

We aim to hold at least one major in-person Coalition event each year, with smaller events throughout the year, including CEO-only events.

Adaptation Working Group

We run a joint Adaptation Working Group with the Sustainable Business Council. The group is co-chaired by IAG and brings together 17 organisations who are working to define what adaptation means for business, raise the profile of business adaptation, and increase adaptation capability across the membership.

Mentoring programme

We operate an opt-in business to business mentoring programme which enables signatories to mentor or be mentored by other signatories on areas to advance their organisation’s climate action. This allows for peer-to-peer support.

Support to meet the Statement of Ambition

We release guidance to help signatories meet the Statement of Ambition requirements and continue to look for ways to facilitate opportunities for signatories to build their collective capability and understand good practice including through the monthly Masterclass series and the business-to-business mentoring programme.

Masterclass series

We hold online Masterclasses once a month. These are typically led by a signatory to help others understand good practice and make faster progress on their area of expertise. The Masterclasses focus on topics that enable signatories to build capability and support achievement of the Statement of Ambition requirements.

Championing our signatories’ climate action

We have effective digital channels to amplify our signatories’ climate action. The Coalition is recognised publicly for its business leadership on climate change and signatories have access to Coalition branded collateral to promote their involvement. Through our annual Snapshot Reports, we also transparently demonstrate signatory progress individually and collectively on meeting the Coalition’s Statement of Ambition commitments.

Advocacy for effective climate action

We support Aotearoa’s domestic and international climate commitments and work with SBC to promote the need for cross-party support for effective climate policy that provides the certainty that businesses and communities need to invest and transform. This includes consulting with signatories to develop comprehensive submissions on key climate policies like the Emissions Reduction Plan and National Adaptation Plan.

Monthly updates

We send monthly updates to ensure our signatories are kept up to date about what’s happening in the Coalition, and more broadly in the climate change space.
