Built differently

Sustainability isn't an add-on.
It's a design principle.

Most podcasts don't think about their environmental footprint. We do — from the London spaces we record in, to the partners we work with, to the CO₂ our listeners generate by streaming us. Not performance. Proof.

Our commitments

Three things we're actively building around

Not future promises — design constraints we're working within from day one.

Build sustainability in visibly

A tree planting scheme tied to subscriber milestones. CO₂ transparency built into the website. Sustainability-aligned partners only. Competitors aren't doing this — that's the opportunity.

In progress

Design for circularity

Knowledge doesn't have to be one-directional. Listener voices shape future content. Repeat guests build on earlier conversations. Spaces and materials: cafes, libraries, museums across London, chosen with intention.

Active

Grow with purpose, not just speed

Local UK partners. Sustainability-aligned brands. The right 1,000 founders matters more than 10,000 wrong ones. Our growth strategy reflects that: audiences that matter more than numbers that look good.

What's your listening footprint?

Streaming audio has a carbon footprint. It's small but it's real. Adjust the sliders to see your estimated annual CO₂ from podcast streaming.

Your Listening Footprint

Estimates based on peer-reviewed research from The Shift Project and the Carbon Trust.

Figures use mid-range estimates from The Shift Project (2019) and Carbon Trust (2021), adjusted for UK grid intensity (~233 gCO₂/kWh, IEA 2024). Actual values vary by network, device, and listening context.

✓ Offset

Production CO₂ tracked and offset. Tree planting scheme launching soon tied to subscriber milestones.

Tree Planting

One tree for every 100 subscribers

We're researching the right scheme — one that's credible, visible, and makes a measurable difference. UK-native species. Transparent reporting. No greenwashing.

When we find the right partner, every subscriber milestone plants trees. You'll be able to see exactly where they're planted and what species. Nation- or county-dependent planting based on where listeners are concentrated.

Every decision runs through one question

"Does this move SoundMud forward, and does it leave something better than I found it?"

Forward = closer to the founder community we're building for. Better = circular, intentional, and true to why we're doing this.
