Alternative substrates with #LessPeat to support the Green Transition in horticulture

PEATLESS drives the transition towards sustainable, locally sourced alternatives to peat in horticulture

WHY REDUCE PEAT USE?

The urgent need to protect peatlands and rethink horticulture

Peat is widely used in horticulture due to its excellent growing properties—but its extraction comes at a high environmental cost. The continued reliance on peat threatens Europe’s climate goals, its biodiversity, and the resilience of our food systems.

By reducing peat use, we can protect vital carbon sinks, restore damaged ecosystems, and build a more sustainable future for European horticulture.

The Problem at a Glance

Peatlands in decline

Europe’s peatlands store twice as much carbon as all the forests in the world combined—yet they are being drained and destroyed. This leads to a devastating loss of biodiversity, soil degradation and the collapse of unique ecosystems.

Peat fuels climate change

Peatlands cover just 3% of the Earth’s surface but emit 5–6% of global greenhouse gases when drained. Continued extraction directly undermines efforts to reach net-zero targets.

Horticulture depends on peat

Peat remains a widely used growing medium across Europe. As food production demands grow, so does the pressure on peat resources—underlining the importance of advancing sustainable alternatives.

The PEATLESS Approach

The PEATLESS Approach

PEATLESS brings together 12 partners from 4 countries to develop alternative substrates, empower growers, and influence policies to phase out peat in horticulture.

  • Innovative substrate blends

  • Grower support & social innovation

  • Business models & policy recommendations

WHAT ARE THE OBSTACLES?

What’s holding horticulture back from going peat-free—and how PEATLESS is changing that

Despite growing awareness, many growers still face real-world challenges when trying to reduce peat use. From performance concerns to economic risks, the transition isn’t simple.

PEATLESS is here to unlock progress—through practical innovation, local support, and policy-ready evidence.

Technical

Alternative substrates often struggle to match peat’s performance. Materials vary in availability, consistency, and quality—making large-scale replacement a challenge.

Socio-Cultural

Growers need trusted knowledge, hands-on training and proven results to feel confident. Habits and perceptions take time (and evidence) to shift.

Economic

High upfront costs, thin profit margins and little policy support make it risky for growers and producers to change the status quo.
