Sustainability-Aware Diligence: A Guide for Venture Capital

Sustainability as a lens, not a mandate

At Arkstons VC, sustainability is a screening and resilience filter applied during diligence and sector selection — alongside, never ahead of, financial performance. This stands apart from ESG reporting frameworks that focus on measuring disclosure outcomes after capital is deployed.

The distinction matters. A sustainability-aware diligence process asks whether a business is structurally exposed to capital intensity, policy dependence, or weak moats — and uses that signal to concentrate capital in resilient, efficient models with durable margins.

How it differs from ESG reporting

• ESG reporting measures disclosure metrics (emissions, governance scores, diversity figures) and reports them to LPs and regulators.
• Sustainability-aware diligence uses sustainability factors as a forward-looking risk screen — filtering out structurally fragile business models before underwriting.
• ESG asks what is being reported. Diligence asks what is structurally durable.

Three uses of the lens

1. A screening filter

We screen out capital-intensive, policy-dependent, and low-moat businesses where returns are structurally constrained — regardless of how green the category appears.

2. A resilience signal

Operational efficiency, resource optimization, and long-term business resilience are favorable indicators. They typically correlate with durable margins and pricing power across cycles.

3. Not a reporting goal

We do not optimize for impact KPIs or ESG outcome metrics. Sustainability informs how we assess risk; it is not the outcome we underwrite.

Applying the lens to sector selection

Our six priority sectors — supply chain & logistics, financial systems, energy, industrial operations, health tech, and climate & agtech — were chosen because the underlying businesses build operational infrastructure and mission-critical systems modern organisations depend on. The lens helps us favor workflow-embedded software over hardware-heavy or subsidy-dependent models.

A practical diligence checklist

• Is the business capital-efficient at its current stage?
• Does revenue depend on regulation, subsidies, or policy that could shift?
• Is the product embedded in a workflow customers cannot easily replace?
• Do efficiency gains scale with adoption, or require linear capex?
• Are margins durable through demand cycles?

Why this matters for LPs

A sustainability lens used as a risk filter — informed by globally recognised frameworks including IRIS+ — produces a portfolio of capital-efficient, defensible businesses. Returns come first; resilience is the discipline that protects them.
