The following discussion illustrates a project that is well suited to the capabilities of an independent consultant in the Umbrex Private Equity Practice. This is an illustrative example. Umbrex consultants adapt their methodology, timeline, and deliverables to the specific needs of each client.
1) Client Situation
The client operated across a multi-product private equity platform and required support with Portfolio Decarbonization And Net Zero Pathways in the context of Private Equity. Stakeholders included Mega/Large-Cap Private Equity Buyout Firms coordinating carve-outs and scale platforms, Mid-Market & Lower Mid-Market Private Equity Sponsors institutionalizing ESG standards, Growth Equity Investors (Private Equity) progressing with lean teams, Private Equity Operating Partners & Value Creation Teams orchestrating cross-portfolio programs, and PE-Owned Portfolio Companies executing 100-day plans under sponsor governance. The diagnostic we conducted surfaced structural gaps that slowed emissions reduction, diluted credibility with LPs, and created rework in diligence and exit preparation:
- Unresolved emissions boundaries and baselines
- Scope definitions varied by company; base years were inconsistent; Scope 2 relied on mixed location- vs. market-based methods; Scope 3 coverage was incomplete (limited purchased goods and services, upstream logistics, use-phase).
- Fragmented data and weak lineage
- Activity data (fuels, electricity, refrigerants, fleet, logistics, waste) lived in spreadsheets; supplier data were survey-based with unclear factors; spend-based estimates were not upgraded to supplier-specific factors; audit trails to source systems were missing.
- No consolidated marginal abatement curve (MAC) or investment view
- Efficiency opportunities, fuel switching, onsite renewables, PPAs/VPPAs, logistics optimization, and product redesign were not quantified consistently. There was no carbon price sensitivity, co-benefit capture (OPEX savings), or sequencing across assets.
- Targets and standards not harmonized
- SBTi requirements for Private Equity were not applied consistently; near-term targets were absent in some funds; supplier engagement targets were ad hoc; portfolio coverage targets vs. temperature rating were not understood by deal teams.
- Renewable energy strategy inconsistent
- REC/EAC procurement quality varied; PPAs were unmanaged; residual mix and claims were disputed; location-based vs. market-based narratives conflicted in investor reporting.
- Integration not embedded in 100-day plans and governance
- Decarbonization actions were not part of Day-100 playbooks; IC memos lacked transition/physical risk screens; board oversight and incentives were not linked to emissions intensity and energy cost KPIs.
- Regulatory readiness and disclosure gaps
- CSRD/ISSB alignment was incomplete; SEC/California climate rules were monitored but not operationalized; CBAM exposure was not quantified for relevant portfolios; assurance readiness and evidence repositories were missing.
- Underperforming KPIs
- Emissions intensity plateaued; energy costs volatile; PPA coverage of electricity spend low; % of suppliers with targets minimal; limited pipeline of funded projects; decarbonization not tied to EBITDA/cash bridges; investor Q&A cycles long due to methodology gaps.
2) Project Objective
The primary objective focused on building Scope 1, 2, and 3 baselines, setting Science Based Targets informed by SBTi Private Equity guidance, developing marginal abatement cost curves and capex roadmaps—reducing emissions intensity and aligning portfolio companies and funds to net zero commitments with audit-ready governance.
Secondary objectives included:
- Establishing a consistent GHG inventory methodology (GHG Protocol) with data quality scoring, location- and market-based Scope 2, and prioritized Scope 3 categories.
- Defining decarbonization pathways and portfolio coverage targets (near-term and net-zero), including supplier engagement targets, temperature rating, and interim milestones.
- Building a consolidated MACC and investment cases (NPV/IRR, OPEX savings, carbon price sensitivity) to sequence actions and integrate with capital planning.
- Designing a renewables procurement strategy (efficiency, onsite, PPAs/VPPAs, EACs) and energy management playbooks by region.
- Standing up data architecture and dashboards with lineage for emissions, energy, and cost KPIs; enabling assurance-ready reporting (ISSB/SASB/TCFD/CSRD crosswalks).
- Embedding decarbonization actions into 100-day plans, IC guardrails, and CEO operating reviews; aligning incentives and escalation thresholds.
- Quantifying transition/physical risks (TCFD scenarios), CBAM exposure, and customer/regulatory requirements for exit readiness.
3) Methodology and Approach
Workstream 1: Ambition, Governance, and Target Setting
We defined the boundary, ambition, and decision rights required to move at pace.
- Activities we conducted:
- Confirmed organizational and operational boundaries (equity vs. control approach) and base year selection; agreed materiality thresholds for Scope 3 categories.
- Aligned on SBTi PE guidance target types: near-term absolute/intensity targets, portfolio coverage vs. temperature rating, and supplier engagement targets; defined neutralization strategy for residuals at net zero.

- Stakeholders involved: deal teams, PMO/Value Creation Office, CEOs/CFOs, Operating Partners.
4) Data Request
We requested datasets and artifacts required to baseline emissions, develop MACCs, and define targets and roadmaps. Typical horizons were 24–36 months of activity data and current-cycle plans.
- Activity and energy data:
- Site-level fuels (type, quantity), electricity consumption (kWh, tariffs), EAC/REC purchases, refrigerant top-ups and equipment lists, fleet fuel cards/telemetry, process emissions data, onsite generation output, utility contracts and PPAs.
- Scope 3 inputs:
- Purchased goods/services (spend by category, supplier IDs), capital goods, upstream/downstream logistics (tonne-km, mode), waste (type/tonnes, treatment), business travel and commuting, use-phase assumptions for relevant products (lifetime, duty cycle), end-of-life.
- Emission factors and methodologies:
- Factor libraries used (IEA, eGRID, DEFRA, national inventories), supplier-specific emissions data (where provided), LCA data, assumptions for market-based Scope 2 (residual mix).
- Financial and operational:
- Capex plans, hurdle rates, energy prices/forecasts, carbon price assumptions, maintenance schedules, production volumes, cost of capital, incentives/subsidy eligibility.
- Supplier and contracts:
- Supplier master and segmentation, CDP responses, contract clauses, code of conduct, audit outcomes.
- Reporting and governance:
- Existing ESG disclosures (TCFD/SASB/ISSB), SBTi commitments (if any), board/IC materials, PMO initiative registers, policy statements, risk registers.
- Systems and controls:
- Data warehouse/lakehouse schemas, BI models, data catalog/lineage, RBAC/SoD, evidence repositories, prior assurance findings.
Common data pitfalls included inconsistent base years and boundaries, mixed location-/market-based Scope 2 claims, spend-only Scope 3 without upgrade plans, supplier data without verification, double counting across categories, missing logistics activity data (reliance on spend), and dashboards without evidence linkage for assurance. We established a KPI dictionary, factor governance, and a lineage-first approach before modeling targets and MACCs.

9) Industry Insights
- SBTi guidance for Private Equity clarifies the “how”
- Portfolio coverage and temperature rating approaches, plus supplier engagement targets, allow PE sponsors to set credible targets while recognizing control limitations across holdings.
- Scope 3 is the decider for many sectors
- Spend-based estimates are a start, but supplier-specific factors and engagement are required for credibility and impact; invest early in segmentation, clauses, and data quality uplift.
- Efficiency and electrification usually beat certificates on value
- Efficiency and process optimization often generate positive NPV; PPAs/VPPAs provide long-term cost/volatility benefits; EACs/EU-GOs should complement, not replace, real abatement and require quality criteria.
- MACC plus carbon price creates durable prioritization
- Shadow carbon pricing reveals the true economics under regulatory and customer pressure; sequencing guided by MACC and operational windows avoids stranded capex.
- Assurance readiness is a differentiator
- Data lineage, evidence repositories, and consistent methods reduce investor Q&A cycles and enable faster CSRD/ISSB reporting and transaction diligence.
- CBAM and customer demands raise the stakes
- Exporters to the EU and suppliers to large enterprises face embedded carbon scrutiny; robust baselines, supplier programs, and product LCAs support pricing and access.
- What “good” looks like
- Audit-ready baselines; SBTi-aligned targets; investable MACC and capex roadmap; RE strategy with credible claims; supplier engagement program; TCFD/ISSB/CSRD-aligned reporting; integration into IC, 100-day plans, and CEO reviews; incentives and escalation linked to intensity reduction.
- Near-term watch points
- ISSB/CSRD implementation timelines, SEC/California climate rules; REC/EAC market quality divergence; evolving Scope 3 guidance and TNFD; grid decarbonization variability; financing costs and PPA counterparty risks. Quarterly governance refresh and assurance checks sustain credibility and speed.
