Contains organic matter that stores carbon while supporting plant growth. Healthy soil is one of nature’s most efficient carbon sinks, with the ability to lock away CO₂ for decades.
At Corker, we believe that beautiful gardens should do more than just look good—they
should actively contribute to a healthier planet. That’s why we’re taking a different
approach to sustainability: we’re focused on measuring and maximizing the natural carbon
sequestration of our products.
Every bag of compost, load of topsoil, or bale of bark mulch that leaves our yard carries
with it the potential to capture carbon dioxide from the atmosphere, locking it away in your
garden for years to come. It’s sustainability that works with nature, not against it.
How Our Products Capture Carbon
Our products work with natural processes to remove CO₂ from the atmosphere
and store it in your garden:
Topsoil
Green Compost
Made from garden waste that has absorbed CO₂ during growth. When applied to your garden, it improves soil structure, enhances microbial activity, and continues to store carbon.
Bark Mulch
Created from tree bark that has captured carbon during the tree’s life. As a byproduct of the timber industry, it gives new life to material that would otherwise be wasted, while continuing to store its captured carbon.
Turf
Living grass continuously absorbs CO₂ through photosynthesis, storing carbon in its roots and the soil beneath. A well-maintained lawn is actively fighting climate change with every blade of grass.
Green Compost
Made from garden waste that has absorbed CO₂ during growth. When applied to your garden, it improves soil structure, enhances microbial activity, and continues to store carbon.
Carbon Capture Metrics
01
Green Compost 1 ton captures approximately 0.6-1.3 tons of CO₂ Perfect for: Garden beds, vegetable plots and planting.
02
Bark Mulch 1 cubic meter captures approximately 0.8 tons of CO₂ Perfect for: Decorative beds, weed suppression, and moisture retention
03
Mushroom Compost Spent mushroom compost sequesters carbon by enhancing soil organic matter Studies suggest organic amendments like compost can sequester between 0.5 to 1.5 tons of CO₂ per hectare per year Perfect for: Improving soil structure, promoting plant growth, and increasing carbon storage in soil
04
Turf/Grass 1 square meter captures approximately 0.5-1.5 kg of CO₂ per year. A healthy lawn typically captures more CO₂ with deeper root systems and proper maintenance Perfect for: Creating carbon-capturing outdoor spaces with a 50m radius of environmental benefit.
05
Topsoil 1 ton with 2% organic carbon captures ~73.4 kg of CO₂ Perfect for: New garden creation, lawn establishment, and raised beds
06
Our Estimated Quarterly Impact: 1200+ tons of CO₂ captured That’s equivalent to taking 260 cars off the road for every quarter!
Our Work in Progress
We’re currently developing a Carbon Calculator to better measure the environmental benefits of our
products. This will allow customers to understand their garden’s contribution to carbon sequestration and
make more informed, eco-conscious choices.
While this tool is in development, our goal remains the same—to continually refine our approach and offer
sustainable solutions that genuinely make a difference.
Stay tuned as we roll out more ways to quantify and
improve the impact of every Corker product.
