Environmental Grass Seeds - Putting Carbon back where it belongs....in the soil!

Carbon Grasses

The result of a 17 year R&D programme by the world’s largest seed breeder, representing a paradigm shift in the performance of amenity grass mixtures.

“There are multiple financial, environmental & social benefits from using these innovative Carbon Grasses.”

    • 300% more atmospheric carbon sequestration into the soil sink.
    • Requiring 40% less cutting (enabling sustainable 40% long-term cost savings)
    • Creating carbon credits to off-set against ‘Carbon Footprints’.
    • Extrapolating the results of the 1st UK Carbon Audit of a Park, 300,000 Ha of grass would sequester 2m-3m tCO2 eq/yr.
    • Harder wearing – enhancement of the amenity.  More disease & pest resistant.
    • 50% more drought tolerant – improved colour & water quality.
    • Contributing to the Sustainable Urban Drainage System (SUDS) agenda by enhancing natural drainage regimes to reduce surface water flooding.
    • These deeper rooted grass cultivars improve bank stabilisation.
    • Support enormous microbial diversity and biodiversity value of the environment.
    • Carbon grass enables improved air quality through atmospheric CO2 scrubbing.
    • & more

Sward Swap – What Is It / The Process

The ‘Sward Swap’ (trade-marked) process eradicates the existing grass regime (& weeds) and simultaneously replaces it with Carbon Grass.

It does this without cultivating the ground & releasing existing soil carbon back into the atmosphere.

There are multiple financial, environmental & social benefits of this forward thinking best-practice.

The Sward-Swap Process:

1. Measure

Measurement of GPS area & existing soil organic matter levels

2. Spray

Non-residual systemic herbicide is applied over the prescribed area

3. Over seed

Intensive over seeding through the existing (dying) sward with a disk type over seeder

4. Maintain

Resume regular mowing maintenance as the new sward establishes within the old

5. Monitor

The Climate Change Act 2008 statutory requirements are the foundation of our Carbon Grass Venture Business Plan:

– 2006 UK total emissions 695 MtCO2

– 2050 UK target objective is 150 MtCO2

– Target average annual reduction of *50MtCO2

– 1Ha with Carbon Grass

– 300,000Ha Public Greenspace in UK = 3MtCO2 pa

– Combining Industry + Sports + Private Gardens, estimate approx 2 MtCO2 pa

– If all grass in the UK was Sward Swapped we’d be looking at approx 5 MtCO2 pa=*10%

In the UK, local authorities manage & maintain 27,000 parks & greenspace, at an annual revenue cost of around £1.1 billion.Heritage Lottery Fund ‘State of the UK Public Parks’ – Research Report 2014

We are offering UK local authorities & large land owners the opportunity to have their old, and expensive to maintain grass regimes exchanged (Sward Swapped) for new Carbon Grasses via a leasing agreement:

- Enabling significant & sustainable long term cost savings

- Creating significantly improved grass swards

- NO initial capital outlay for the local authority

- Generating carbon credits to off-set against their 'carbon footprint'

- 'Shared Savings' in consideration

NB: The intellectual property & brand value in the integral Carbon Grass products & Sward Swap process is protected with UK & Eurpoean Patents, Trade-Marks & an exclusive Long Term Supply Agreement.

Case Study / Feedback – Torbay Council

“Money is saved because the new verges require less cutting and produce less risings, which means less wear on our mowing machines, less manpower, a reduction on blocked hulleys & the costs associated with clearing up.
More than 95% of the grass needs only 3 or 4 cuts a year as opposed to 7 or 8 previously. We live in an era of ever decreasing budgets so the number of times you can cut the highways is reducing.
By looking at specific cultivars and putting some of the new low maintenance grasses in a place you can not only reduce the number of cuts but also maintain a far better visual effect.
Basically you have to invest short-term to save long-term.”
