Sustainability
Carbon Reduction Plan
MJS Construction (March) Ltd is committed to achieving net zero carbon emissions by 2045, in line with national and international climate goals.

We recognise the urgent need for climate action and the leadership role we play as a groundworks and reinforced concrete specialist in shaping a low-carbon built environment. We publish this plan and report on our progress annually. Our approach prioritises emissions reductions at the source, with offsetting as a last resort. A key milestone is to make the majority of emissions cuts by 2030, setting out a clear trajectory from our 2022 baseline.
Scope of the plan
We measure and reduce emissions across three categories:
- Scope 1: direct emissions from owned or controlled sources — company vehicles, plant, generators.
- Scope 2: indirect emissions from purchased energy — electricity for offices and compounds.
- Scope 3: indirect emissions from our value chain — embodied carbon in concrete, purchased goods, subcontractor emissions, employee commuting, waste.
Progress, 2022 to 2025
Because our output varies significantly year to year, carbon intensity (emissions per £m of turnover) is the clearest measure of underlying progress. By 2025 we had reduced our carbon intensity by 64% against our 2022 baseline — already exceeding our 50%-by-2030 interim target — with absolute emissions 44% below baseline despite turnover increasing by 57% over the same period.
| Metric | 2022 | 2023 | 2024 | 2025 |
|---|---|---|---|---|
| Total emissions (tCO₂e) | 7,007 | 3,470 | 4,551 | 3,904 |
| Turnover (£m) | 13.4 | 13.2 | 10.6 | 21.0 |
| Carbon intensity (tCO₂e / £m) | 523 | 263 | 429 | 186 |
| Change vs 2022 | baseline | -50% | -18% | -64% |
Absolute emissions rose between 2024 and 2025 — this reflects business volume rather than any decline in carbon performance: turnover nearly doubled (from £10.6m to £21.0m), and as a concrete and groundworks specialist the bulk of our footprint is embodied carbon in concrete and steel, which scales with workload. Over the same period our carbon intensity fell to its lowest level on record, and our 2025 concrete tonnage remained below the 2022 baseline, reflecting more efficient material use.
Net zero target: 2045 · interim target: 2030
We aim to reach net zero by 2045 across all relevant scopes, reducing emissions at source wherever possible. We commit to reducing our net Scope 1, 2 and relevant Scope 3 emissions by at least 50% by 2030 versus our 2022 baseline, on a carbon-intensity basis — exceeding the UK Government's 2030 target of 43% for the construction sector. As above, we had already achieved a 64% intensity reduction by 2025.
Carbon literacy & leadership
We have implemented a Carbon Literacy Programme across our business to build understanding and capability at all levels, especially within our leadership team and those influencing project design and procurement. 50% of total staff have completed carbon literacy resources provided by the Supply Chain Sustainability School, covering embodied and operational carbon in construction — including the leadership team and roles influencing project design, procurement and delivery.
Key reduction strategies
Plant & equipment
- Transition to Stage V compliant and electric/low-emission machinery (EV plant now in use).
- Phase out diesel generators and explore battery storage.
- Use telematics to track and optimise usage.
Fleet & transport
- Gradual phasing out of vans for electric vehicles.
- Promote shared transport, public transport and cycling.
- Route optimisation for materials and staff logistics.
Energy use
- 100% renewable grid electricity procurement.
- Rooftop solar PV installed at our offices (operational since late 2022).
- Improve site and office energy efficiency (LED lighting, smart systems).
Materials & supply chain
- Use low-carbon concrete mixes, cement replacement and recycled aggregates.
- Work with suppliers with science-based targets.
- Apply PAS 2080 principles to embodied carbon reduction.
Waste & circular economy
- Cut landfill waste by 75% by 2030.
- Reuse site materials where possible.
- Promote circular practices in design and procurement.
Digital tools & innovation
- Use carbon modelling tools, linked to BIM and scheduling.
- Pilot innovations like carbon-cured concrete.
- Report project-level emissions and share learning.
Monitoring, reporting & governance
- Annual GHG emissions audits aligned with the GHG Protocol and PAS 2080.
- Sustainability Lead appointed.
- Annual publication of progress against targets, reported on both an absolute and carbon-intensity basis.
- Carbon KPIs incorporated in project dashboards.
- Encourage external validation of progress where appropriate.
Offsetting strategy
We offset only residual emissions that cannot be reduced, using verified carbon removal schemes, preferably UK-based, and will not begin offsetting before 2035 — only as a supplement to genuine reductions.
