Sustainable Manufacturing Proof Point
Show that emerging-market factories can decarbonise production and still compete on cost.

The ask
Build a small-batch, export-grade Bangladeshi manufacturer — garments, packaging, or light industrials — that runs on renewables and can document its carbon footprint per unit, providing a replicable proof point that low-wage economies can decarbonise without killing margin.
Why now
The EU Carbon Border Adjustment Mechanism (CBAM) and Scope 3 supply-chain disclosure rules are pushing global brands to demand verified low-carbon inputs. Bangladesh's RMG sector is the country's economic backbone, but most factories still run on grid power that is 60%+ fossil. A certified green factory that can demonstrate cost parity becomes a commercial reference and a policy case study worth far more than its own revenue.
Why Bangladesh
Bangladesh is the world's second-largest garment exporter; EU buyers are already issuing 2026–2030 decarbonisation ultimatums to tier-1 suppliers. Solar rooftop costs have dropped below grid tariffs in the industrial belt; the local skills base for light manufacturing is deep. A single factory that achieves RE100 status and publishes its unit economics becomes a blueprint every trade association in the country wants to replicate.
As a business
The factory earns a green premium (5–12%) on export contracts with brands committed to Scope 3 targets. Secondary revenue comes from consulting fees — the methodology, energy audit tools, and procurement playbook are licensable to other factories. Over time the model morphs into a certification-and-services business attached to a credible operating reference.
Economics
Move the sliders to model your own green-factory upgrade. Defaults are order-of-magnitude estimates — pressure-testing them is part of what a founder pitches us.

Illustrative model — defaults are order-of-magnitude estimates from public data, not a forecast. Pressure-test every number before you build.
What ZEPH would back
An operator who already runs a profitable factory and wants to reposition it as a climate reference — not a first-time founder building green from scratch. ZEPH would co-invest on the energy capex in exchange for rights to publish and license the methodology.
Impact
A factory generating ৳30 crore in annual exports that switches to solar and documents its Scope 3 emissions avoids roughly 180–250 tCO₂e per year from grid electricity alone. The larger impact is systemic: Bangladesh's 206 LEED-certified garment factories collectively represent less than 2% of the RMG sector — a credible, published proof-point with open-source methodology could accelerate adoption across hundreds of factories and potentially avoid 2–3 million tCO₂e per year at sector scale. The green premium revenue directly improves Bangladesh's trade terms with EU buyers facing CBAM obligations from 2026.
