Sunya undertakes sustainable practices seriously and offers a wide range of technologies and approaches to reduce environmental impact. She addresses four key concerns.

Water use

• Drought tolerant species (ecological planting)
• Autumn planting and use of small plants where possible.
• Grey water recycling and rain water harvesting.
• Soil management.
• Sustainable drainage systems such as permeable paving for reduction of water run off into mains, drains and sewers.

Waste

• Reduce
• Recover
• Reuse
• Recycle

Use of sustainable material

• Soil association accredited seeds and plants.
• Peat free or reduced-peat products as an alternative.
• Low energy use during manufacture.
• Low CO2 emissions
• Fair trade and FSC/PEFC certified timber.
• Materials on site that can be sensibly salvaged are reused and recycled.
• Traditional hard landscaping techniques if feasible

Tree health

• Always aim to plant UK sourced trees with proven seed provenance. This makes biological sense and it reduces the chances of introducing alien pests and diseases.
• Only use trusted suppliers renowned for the traceability of their seeds, plants, shrubs and other horticultural products.
