We exist to accelerate climate solutions.
By giving climate startups and NGOs the professional sales and marketing they need at the crucial early stage, when it makes the biggest difference.
Great climate solutions deserve to be heard
Audience reach used to be measured by the "man on the Clapham omnibus" but no more, reaching your audience and growing your sales base is far more complex.
Climate Marketing Lab closes that gap, by connecting mission-driven ventures with senior marketing and sales talent, supported by lean professional leadership and AI-powered tools, at a fraction of agency cost.
When we say climate, we mean the whole field: Climate, climate-tech and sustainability. Throughout this site we use “climate” as shorthand for all three.
Paul Savill
Climate Marketing Lab was founded by Paul Savill as a volunteer-led initiative, built on the conviction that experienced marketers and sales professionals can be one of the climate movement’s most powerful, under-used resources.
A volunteer-founded answer to a commercial problem
CML began with a simple observation: many climate founders kept hitting the same commercial sales wall, and a global pool of senior professionals kept looking for a meaningful way to help. We built the bridge between them.
Our model pairs a community of senior volunteers with lean professional leadership and modern AI tools, combining the quality of an agency with the mission and economics of a volunteer movement.
Half of our net profit funds the next climate venture
Once a venture grows beyond our £200/month volunteer tier, CML can work with them commercially, like a dedicated agency. But unlike a normal agency, that commercial work carries the mission forward.
Our promise is simple: half of CML’s net profit is reinvested into other climate and sustainability ventures, funding the managed and sponsored support that lets earlier-stage startups and NGOs get the help they could not otherwise afford.
So when a successful client chooses CML for paid, agency-grade work, they aren’t just buying excellent sales and marketing. They are compounding climate impact: their spend directly accelerates the next wave of ventures behind them.
For our clients
Agency-grade delivery from the team that already knows your story, with purpose built in.
For the mission
Half of every net profit pound flows back to ventures that can’t yet pay, a self-sustaining engine for climate impact.
Senior expertise, generously given
Our first LinkedIn wave drew more applicants than we expected at at a much more senior level than we were expecting. Our community already spans some formidable backgrounds.
What we stand for
Mission first
We only work on climate, climate-tech and sustainability, because focus is what makes us genuinely useful.
Bold & clear
Be bold, brave and to the point. Climate marketing that hedges doesn’t move anyone.
Trusted & confidential
We treat every venture’s work in strict confidence, with clear expectations on both sides.
