Regenerative cotton is becoming increasingly available, but navigating the market is not always straightforward. Different sourcing pathways offer different levels of traceability, evidence and engagement with farmers. So how should brands think about their options, and what do their choices mean for the market that develops?

Regenerative leather is being defined right now, and there's an opportunity to shape it. There's no single certification, no agreed definition, no established market signal that tells a farmer or a tannery "do this and you'll get paid more for it." That's not a reason to wait. It's the reason to move. What exists right now is a handful of pilot projects, a lot of goodwill, and an industry trying to figure out what regenerative actually means for a material that is largely a byproduct of animal agriculture. This is where early projects matter. Brands willing to support pilots now and learn from what works and what doesn't can help shape what this sourcing market looks like in practice. The projects that get support today are the ones that will tell the rest of the industry what actually holds up in two or three years.

Healthy ecosystems are the foundation of resilient societies, yet they remain chronically underfunded. Using Acción Andina's work across the Andes as an example, we explore why nature should be treated as critical infrastructure, and why long-term, holistic investment is essential to protect it.

At Milkywire we are always asking the same question: how do we make every dollar invested for climate and nature as catalytic as possible? To us, catalytic means leverage. It means stepping in where others won't, generating learning that benefits the wider ecosystem and building things that outlast our funding. That north star shapes every funding decision we make. With climate funding in retreat globally, doing more with less has become even more urgent.

The Milkywire Climate Transformation Fund invites organisations to apply for its 2026 Open Call for Proposal under the Nature Protection & Restoration and Decarbonization Pillars. We seek high-impact projects that remove barriers to implementation, unlock innovation, and accelerate systemic climate transformation at the speed and scale required by climate science. Milkywire also invites expressions of interest (via a separate form) from organizations developing high-quality nature-based carbon credit projects, including those already certified or with a clear pathway to certification under recognized voluntary carbon market standards.
