Who We Are

We are Engineers, Scientists, and Strategists

Lumin Advisory is not a traditional management consultancy. We are a technical collective built to solve the physical and regulatory challenges of the sustainable transition.

Our team brings together distinct disciplines that rarely sit at the same table: chemical engineering, environmental data science, supply chain operations, and corporate strategy. This cross-disciplinary approach allows us to speak the language of your R&D team and your Board of Directors. We partner with experts as needed by the contracting projects.

Service Pillars

We guide you from high-level strategy to quantifiable, audit-ready data with our four core competencies.

Climate Strategy & Decarbonization

GHG Accounting · Decarbonization · Climate Risk Assessment

Turn ambition into verified action. We build audit-ready GHG inventories (Scope 1–3) and design science-based decarbonization roadmaps. By quantifying physical and transition risks, we ensure your climate strategy is financially resilient, compliant with SBTi standards, and ready for scrutiny by investors and auditors.

Sustainable Products

LCA, PCF and verification services

We quantify the environmental footprint of your products using ISO-aligned LCA and Product Carbon Footprint methods. From screening studies to customer-facing EPDs, we translate complex models into clear claims and reduction roadmaps. We also support third-party verification, data collection, and supplier engagement to strengthen your product sustainability story.

Critical Raw Materials Intelligence

CRM Supply & Demand · Sourcing

Secure your supply chain against volatility. We analyze Critical Raw Material (CRM) exposure, modeling supply, demand, and circularity risks specific to your materials. Our intelligence supports strategic sourcing decisions, helping you navigate geopolitical constraints and price fluctuations while optimizing material recovery and resilience.

Success Stories

Case Studies

Real-world examples of how our methods drive measurable outcomes.

Product Carbon Footprint

PCF of Semi-Finished Goods

Context

A mid-tier industrial supplier, specializing in engineered metal components, needed ISO 14067-aligned cradle-to-gate Product Carbon Footprints (PCFs) for a portfolio of 11 semi-finished products. The goal was twofold: meet increasing OEM disclosure demands and identify internal cost-reduction opportunities through decarbonization.

Project & Findings

The project delivered verified PCFs within eight weeks, focusing on mass-balancing and high-quality secondary datasets to address data gaps. While initial data coverage was low, it was rapidly expanded to provide high-fidelity results. The analysis pinpointed the single largest hotspot: an inefficient energy recovery system in a high-temperature finishing process.

Impact

By optimizing the identified hotspot, the supplier realized a measurable carbon reduction on a priority product stream, directly linked to significant energy savings and lower operating costs. Furthermore, the robust, verified data enabled the supplier to present a compelling narrative, resulting in first-pass OEM acceptance with zero corrective actions. The supplier successfully demonstrated a competitive advantage, proving their components hold a lower carbon intensity than key market competitors.

Scope 3 Emissions

Scope 3 Accounting & Supplier Engagement

Context

A global manufacturing player committed to the Science Based Targets initiative (SBTi) but lacked granular visibility into its supply chain (Scope 3), which accounted for >80% of total emissions. Reliance on spend-based estimates was masking critical hotspots and preventing actionable reduction strategies.

Project & Findings

We deployed a tiered supplier engagement strategy combined with a hybrid calculation methodology. Screening: Conducted a materiality assessment to identify the top suppliers contributing to 70% of emissions. Engagement: Launched a targeted data collection campaign, moving key suppliers from generic spend-based factors to physical intensity data (e.g., kgCO2e/kg product). Capacity Building: Delivered workshops to upskill suppliers on GHG accounting and roadmap creation.

Impact

The transition to primary data identified that actual emissions were 22% lower/higher than initial estimates, allowing for a re-baselining of targets. The company successfully validated its near-term targets with the SBTi. Crucially, the program secured commitments from 65% of strategic suppliers to set their own renewable energy targets within 24 months, significantly de-risking the client's long-term transition plan.

Critical Raw Materials

Critical Raw Materials Analysis for Gallium & Germanium

Context

High dependency on Gallium & Germanium for semiconductor/optical products. Supply chain critically vulnerable due to >90% concentration in a single region (China) and active export controls.

Project & Findings

Conducted deep-dive market analysis identifying single-source risks. Developed a 'China Plus One' multisourcing strategy and validated secondary supply streams via high-purity recycling.

Impact

Mitigated immediate supply disruption risks. Avoided >40% spot market price surges and secured long-term compliance with critical mineral regulations.

Insights

Strategic perspectives on the evolving sustainability landscape

Emissions

Scope 3 is about 80–90% of all emissions — but none are under direct control

Most companies now realise the bulk of their footprint sits in Scope 3 – upstream and downstream activities they don't own or operate. The challenge isn't just measurement, but influence: how to work with suppliers, customers and designers to shift decisions you don't directly control.

Strategy

Carbon shadow pricing reflects the real cost of a product

A growing number of companies are assigning an internal carbon price to products, projects and investments. This shadow price doesn't appear on the invoice, but it changes decisions: which materials to choose, which suppliers to favour, and where decarbonisation projects suddenly become financially attractive.

Supply Chain

Critical Raw Materials have become a mainstream topic — what's next?

Critical raw materials have moved from expert reports to boardroom agendas. The next step is moving beyond lists and flags to concrete action: mapping where CRMs sit in your portfolio, stress-testing supply scenarios, and designing products and sourcing strategies that are both resilient and genuinely more sustainable.
