RETICEO–SENAT Programme · Low-carbon Infrastructure

Environmental Impact

RETICEO turns educational spending into a low-carbon model: 100% solar, no grid or diesel, replacing paper and energy-intensive infrastructure. The indicators below are indicative estimates based on SENAT programme parameters and standard emission factors.

Indicative estimates — to be confirmed by a full Life Cycle Assessment (LCA). Detailed methodology in section 4. At full SENAT scale: 5,200 schools · 1.5 million pupils.

The pillars

Environmental Pillars

Three structural levers make RETICEO a measurable, auditable low-carbon educational infrastructure.

100% Solar Energy — CeRSER

Each SENAT school is powered by the CeRSER kit (solar panels + batteries + regulator): no national grid, no diesel generator. The system covers continuous needs — servers, ZEP-X terminals, lighting, and pedagogical air conditioning.

☀️ ~0.6 kWh/day/school · ~3.1 GWh/yr (5,200 schools)
  • Cameroon grid emission factor: ~0.27 t CO₂e/MWh
  • Diesel generator factor: ~0.27 kg CO₂/kWh (conservative estimate)
  • Estimated saving: ~840 t CO₂e/yr on energy alone

Zero Paper — ZEP-X Terminals

The ZEP-X terminal replaces all physical paper: textbooks, exercise books, exam papers, reports, and exam invitations. Per pupil per year, a conventional school consumes 5 kg of paper. At 1.5 million pupils, digital substitution represents a massive saving in wood pulp and water.

📄 ~5 kg paper/pupil/yr → ~7,500 t/yr avoided · ~127,000 trees preserved
  • 1 tonne of paper = ~17 trees (ADEME/WWF standard)
  • Paper production: ~1.3 t CO₂e/tonne (global average)
  • Estimated saving: ~9,750 t CO₂e/yr on paper

Lean Infrastructure — RENAL-SMART

The RENAL-SMART 80/20 network operates without Internet, without long-distance fibre, without an external data centre. Each school's Smart Local Cloud is a low-power server running on solar energy. No physical movement of educational materials (textbook deliveries, exam paper collection).

🌐 100% offline · Zero textbook transport · Server <50 W/school
  • Zero data flows to third-party cloud (zero indirect digital impact)
  • Elimination of textbook delivery rounds (~8 trucks/region/yr)
  • Estimated saving: ~710 t CO₂e/yr (logistics + cloud)

Methodology

Calculation Methodology

Estimates are based on SENAT programme parameters (number of schools, pupils, unit consumption) and recognised emission factors. All assumptions are conservative.

Energy — CeRSER Kit

Assumptions used:

  • Unit school consumption: 600 Wh/day
  • Cameroon grid emission factor: 0.27 t CO₂e/MWh (IEA 2022)
  • Diesel generator factor: 0.27 kg CO₂/kWh
  • Assumption: 50% of schools would have used diesel without CeRSER
E_avoided = N_schools × 600 Wh × 365 × EF_grid
= 5,200 × 0.6 kWh × 365 × 0.27 t/MWh
≈ 307 MWh/yr → ~83 t CO₂e/yr (grid)
+ diesel (50%): ~757 t CO₂e/yr → Total ≈ 840 t CO₂e/yr

Paper — ZEP-X Terminals

Assumptions used:

  • Paper consumption per pupil/yr: 5 kg (textbooks + exercise books + exam papers)
  • SENAT pupils (full scale): 1,500,000
  • EF paper production: 1.3 t CO₂e/t (ADEME 2021)
  • Tree equivalent: 1 t paper = 17 trees (WWF/FSC)
Paper_avoided = 1,500,000 × 5 kg = 7,500 t/yr
CO₂e_avoided = 7,500 × 1.3 = 9,750 t CO₂e/yr
Trees = 7,500 × 17 = ~127,500 trees/yr

Logistics — Textbook Delivery

Assumptions used:

  • 8 administrative regions, ~650 schools/region on average
  • 8 10-tonne truck rounds/yr/region (textbook distribution)
  • Average return distance: 320 km/round
  • EF 10t diesel truck: 0.18 kg CO₂/t.km (ADEME freight)
CO₂e = 8 regions × 8 trucks × 320 km × 10 t × 0.18 kg
= ~369 t CO₂e/yr ≈ 360 t CO₂e/yr

Exams — RETICEO EXAM

Assumptions used:

  • 2 exam sessions/yr × 1,500,000 pupils
  • Paper per pupil per exam: 80 g (question paper + answer sheets)
  • Secure question paper transport: 16 rounds/region/yr (2 sessions)
  • Post-exam destruction: burning → factor 0.5 kg CO₂/kg paper
Paper = 1,500,000 × 2 sessions × 80 g = 240 t/yr
CO₂e prod. = 240 × 1.3 = 312 t
CO₂e transport + destruction ≈ 48 t
Total ≈ ~360 t CO₂e/yr
Limitations and uncovered scope: These estimates do not include: (1) the carbon footprint of ZEP-X terminal manufacturing (~710 g CO₂e/terminal, i.e. ~1,065 t CO₂e for 1.5M terminals — amortised over 7 years), (2) end-of-life equipment, (3) pupil home-to-school travel emissions. A full LCA per ISO 14040/44 is recommended to refine these figures.

End-of-life & circularity

E-waste Management & Circular Economy

RETICEO addresses equipment end-of-life from the design stage, turning electronic waste (WEEE) into local value rather than an externality — in line with IFC PS3, the Basel Convention and the spirit of the WEEE Directive.

Eco-design & Second Life

ZEP-X terminals are designed to be durable, modular and repairable — target lifespan 6 to 7 years. Refurbishment and redeployment are systematically prioritised before any recycling. A refurbished terminal re-enters the school fleet or is redirected to other educational uses.

🔧 Target lifespan: 6–7 years · ~3 renewal cycles over 20 years

Take-back Scheme

Dedicated collection points are organised in SENAT schools. End-of-life equipment is recovered through the local NETSCOM/DIGITEC network, ensuring end-to-end traceability and the creation of local green jobs (collection, sorting, pre-diagnosis).

📦 Target collection rate ≥ 90% · NETSCOM/DIGITEC network

Certified Recycling & Traceability

Material recovery is entrusted to certified recyclers with documented tracking from collection to final valorisation. Hazardous fractions (Li-ion batteries) are directed 100% to specialist streams. The whole process is integrated into RETICEO's annual ESG reporting.

♻️ Material recovery ≥ 85% · Batteries 100% certified stream · ESG reporting
