Fund climate impact — and engage your people.
Inspired by proven corporate-responsibility models, your sponsorship funds professional sales & marketing support for climate startups and NGOs that could not otherwise afford it.
Back a cohort. Multiply the impact.
Sponsor a cohort of early-stage climate startups or NGOs. CML delivers the managed support; you receive meaningful brand association, employee engagement and a clear impact report.
- A defined cohort of vetted climate ventures or NGOs
- Full delivery by CML’s senior volunteers and management
- Regular updates throughout the programme
- A clear, shareable impact report
- Co-marketing and brand association

The cross-subsidy model
Your investment removes the single biggest barrier (budget) for the climate ventures with the least access to professional growth support.
Brand association
Align your organisation with credible, measurable climate action, not greenwash, but real ventures making real progress.
Employee engagement
Give your people a tangible connection to climate impact, and a reason to be proud of where they work.
Clear impact reporting
Receive a structured report on the cohort’s progress, outcomes you can share with stakeholders and in ESG disclosures.
A Climate Marketing Sprint for your team
Bring your people into the work directly: corporate teams take part in a focused “Climate Marketing Sprint” workshop, supporting a real climate startup. Team-based corporate responsibility and genuine skills development, all in one engagement.
