Sustainability Statement.

Spalce Technologies Ltd is committed to reaching net-zero greenhouse-gas emissions across Scope 1, Scope 2, and material categories of Scope 3 by 2040, with an interim target of a 50 percent reduction in Scope 1 and Scope 2 emissions by 2030, against a 2024 baseline.

As of the publication date of this statement, all Spalce-operated cloud infrastructure runs on providers that publish documented renewable-energy procurement (power purchase agreements, renewable energy certificates, or direct grid matching). The energy consumed by our offices in Accra, Lagos, and Nairobi is offset on an annual basis through certified carbon-offset programmes pending direct renewable supply at each site.

We treat sustainability as a board-level matter, not a marketing one. Targets, methodology, and progress are reviewed quarterly by our executive team and at least annually by our board.

Our climate strategy is organised around three pillars, in the order they are prioritised internally: measure, reduce, and only then offset. We do not regard offsets as a substitute for absolute emissions reductions.

Measure

We measure Scope 1, Scope 2, and the material categories of Scope 3 emissions following the Greenhouse Gas Protocol Corporate Standard. Reporting boundaries are operational control. Data is collected monthly from utility providers, cloud-vendor sustainability dashboards, travel-management systems, and employee commuting surveys, and is consolidated quarterly. Methodology and assumptions are disclosed publicly through our annual CDP (Carbon Disclosure Project) submission.

Reduce

We treat efficient code as climate code. Right-sizing infrastructure, eliminating idle workloads, and decommissioning end-of-life services are part of how engineering work is reviewed before it ships. Reduction levers, in order of impact for our profile, are: workload right-sizing and autoscaling, region selection in favour of grids with higher renewable mix, batch and asynchronous workloads where latency permits, edge caching for content-heavy paths, and aggressive end-of-life of dormant services.

Offset

Residual emissions that we cannot yet eliminate are offset annually through verified projects certified to the Gold Standard or to Verra's Verified Carbon Standard. Project selection prioritises African nature-based solutions and community-benefit projects (such as cookstove replacement in West Africa) over generic industrial offsets, subject to the same additionality and permanence criteria as any other offset purchase.

The table below summarises Spalce's 2025 operational greenhouse-gas footprint, reported in tonnes of carbon-dioxide equivalent (tCO2e). The figures are subject to limited external assurance and will be republished in full in our 2026 annual sustainability report.

Scope 3 reporting currently covers business travel, purchased cloud services, and employee commute. We are expanding Scope 3 coverage to include purchased goods and services, capital goods, and downstream emissions from customer-deployed software over the next two reporting cycles.

The largest share of our footprint sits with the cloud providers we deploy on. We require that strategic cloud partners (Amazon Web Services, Microsoft Azure, and Google Cloud Platform) publish a credible path to 100 percent renewable-energy matching for the regions in which we run customer workloads, and that they expose per-workload carbon data to their customers.

Internally, we track which Spalce-operated workloads run in regions that the provider documents as renewable-energy-matched on an annual basis. Where customer requirements and latency permit, new workloads are placed in regions with the strongest documented sustainability disclosures (for example, AWS af-south-1 in Cape Town for South African data residency).

Where a cloud provider's reported figures are inconsistent with independent grid data, we surface this in our internal sustainability review and weight the location-based calculation accordingly.

The carbon impact of a software system is largely decided at design time. Spalce builds software with carbon as a non-functional requirement alongside performance, security, and accessibility.

• Right-sizing: services are deployed at the smallest compute footprint that meets the documented performance target, and revisited quarterly.
• Autoscaling: services scale down (including to zero where the architecture permits) outside of demand windows, rather than running at constant peak capacity.
• Cold-start mitigation: where cold starts would otherwise force over-provisioning, we use scheduled warming or provisioned concurrency only on the critical-path endpoints that require it.
• Batch by default: non-interactive workloads (reports, exports, model training, data sync) are executed asynchronously and scheduled toward windows with greener grid intensity where the provider exposes that data.
• Edge for content-heavy paths: static and cacheable content is served from edge locations close to the user to reduce origin traffic and unnecessary cross-region transit.
• Aggressive end-of-life: dormant services and unused environments are decommissioned on a quarterly cadence, not left running indefinitely.
• Carbon-aware observability: dashboards expose per-service compute and storage cost trends as a proxy for carbon, so engineers see the impact of their changes.

Spalce was founded in Ghana, and a meaningful share of our annual budget is committed to programmes that broaden access to careers and capital in African technology.

Spalce Bridge

Spalce Bridge funds 30 paid internships per year for African students from under-represented backgrounds in STEM. Interns work on real customer engagements, are paid a living stipend at parity with the local cost of living, and are paired with a senior engineering mentor for the duration of the programme.

Open Africa Code Grants

Each quarter, Spalce issues four micro-grants to open-source projects with maintainers based in Africa, with the aim of compensating maintenance work that is structurally underfunded. Grants are awarded on the basis of project utility and maintainer-time disclosure rather than star count, and are paid without an equity, licensing, or attribution claim attached.

Pro-bono Engineering

Spalce delivers three pro-bono engineering engagements per calendar year for vetted non-profit organisations operating in education, public health, or climate. Engagements are scoped and resourced in the same way as a paid engagement, with the same expectations on quality, security, and accessibility.

Sustainability oversight at Spalce sits with the board. A non-executive director holds the ESG portfolio and chairs an internal Sustainability Committee that meets quarterly. The committee reviews progress against published targets, approves the annual report before publication, and signs off any change to the underlying methodology.

Spalce publishes a full sustainability report on an annual basis. The next report is scheduled for publication in Q4 2026. Methodology, restatements, and assurance scope are disclosed alongside the headline figures.

Spalce is a signatory to the United Nations Global Compact and aligns its operations with the Compact's Ten Principles on human rights, labour, environment, and anti-corruption. We prioritise contributions to the following UN Sustainable Development Goals where they best fit our footprint and our work:

• SDG 5: Gender Equality, through hiring practice, pay-gap reporting, and the Spalce Bridge internship programme.
• SDG 8: Decent Work and Economic Growth, through living-wage commitments and responsible sub-contracting.
• SDG 9: Industry, Innovation and Infrastructure, through investment in African open-source maintenance and developer capacity.
• SDG 13: Climate Action, through the climate strategy described in this statement.

Suppliers, contractors, and sub-processors engaged by Spalce are required to sign the Spalce Supplier Code of Conduct, which sets minimum standards on human rights, labour conditions, anti-bribery and corruption, data protection, and environmental management. The current version of the code is available on request and is referenced in our procurement contracts.

Spalce publishes an annual Modern Slavery Statement aligned with section 54 of the United Kingdom Modern Slavery Act 2015 and the equivalent provisions of the Ghanaian Human Trafficking Act, 2005 (Act 694), and similar legislation in other jurisdictions in which we operate or sell. The statement describes the steps taken to assess and address the risk of modern slavery and human trafficking within our operations and supply chain.

Spalce maintains an anti-bribery and corruption policy aligned with the UK Bribery Act 2010 and the U.S. Foreign Corrupt Practices Act, and a confidential whistleblowing channel that allows employees, contractors, and suppliers to raise concerns without retaliation.
