How Aranca Delivers Evidence-Based Sustainability Advisory
We are a specialist sustainability and climate advisory practice working with corporations, financial institutions, public sector bodies and governments. We translate sustainability ambition into commercial strategy, operational execution and disclosure that meets the highest standards of analytical rigour.
Our work spans the full agenda: net zero roadmaps, climate technology investment, ESG due diligence, green finance structuring and mandatory reporting under CSRD, IFRS S1 and S2, TCFD and GRI. Every engagement is grounded in primary research, sector-specific intelligence and the commercial depth to make recommendations that hold up under the scrutiny of investors, regulators and boards.
The organizations we work with share one thing in common: they treat sustainability as a strategy question before it becomes a compliance question. We give them the evidence, the analytical foundation and the end-to-end capability to act with confidence rather than react under pressure.
- Assessing commercial viability and investment opportunity across new energy technologies such as green hydrogen, CCUS, renewables and energy storage

Sustainability and Climate Solutions for Business Transformation
The sustainability challenge facing organizations today does not fit into a single workstream. A corporation navigating CSRD disclosure is also managing Scope 3 pressure from its supply chain and green market opportunity in its product pipeline. Our six practice areas reflect that complexity - each a dedicated capability, all connected by a commitment to evidence-based advisory.
Sustainable Growth Advisory
The green economy is not a future scenario. It is reshaping buyer requirements, redirecting investment and creating new competitive dynamics right now. The organizations capturing value from it moved before the opportunity became obvious - with evidence on where demand is real, which markets are accessible and what winning actually requires. We help you get there first, with the market sizing, customer intelligence and go-to-market strategy to back every decision.
- Market Opportunity & Demand Analysis
- Customer & Stakeholder Intelligence
- Product & Service Innovation
- Market Entry Strategy for Climate Tech Sectors
Low-Carbon Climate Technologies
Hydrogen, CCUS, advanced nuclear, next-generation renewables, battery storage and alternative fuels are being deployed at scale and attracting record capital. For investors, project developers and corporate strategists, the challenge is knowing which technologies are commercially ready for your specific situation and which strategies hold up as cost curves shift. We help you separate the commercially viable from the speculative, identify the partners worth pursuing and build a technology strategy grounded in evidence.
- Green Hydrogen & Derivatives
- Carbon Capture, Utilization, and Storage (CCUS)
- Energy Transition & Renewable Energy
- Battery
- Alternative Fuels
- Nuclear
Net Zero and Decarbonization Transformation
The distance between a net zero commitment and a credible, costed, board-approved plan is where most organizations are right now. Investors are stress-testing transition plans. Supply chains are demanding verified emissions data. Regulators are moving from voluntary reporting to mandatory disclosure with assurance requirements. We help you close that gap with an emissions baseline you can defend, a reduction strategy sequenced around commercial reality and a roadmap built to hold up under scrutiny from every direction.
- Scope 1 & 2 - Emissions Monitoring & Accounting
- Product & Process Decarbonization
- Scope 3 & Value Chain Decarbonization
- Circular Economy
- Net Zero Roadmap
Sustainable Finance and Responsible Investment
Climate and ESG risk is already priced into the deals and portfolios of the organizations paying attention to it. For everyone else it is accumulating quietly - in transition-exposed assets, in governance gaps that surface during due diligence, in financed emissions regulators are increasingly requiring to be disclosed. We help you see it clearly: assessing risk at the transaction and portfolio level, structuring green finance that opens access to ESG-mandated capital and building investment frameworks that satisfy your LPs, lenders and regulators.
- Responsible Investment Advisory
- Sector level and Portfolio Risk Analysis
- M&A Feasibility Study and Due Diligence
- Green Finance
- Sustainability in Private Equity
- Financed Emissions
ESG Strategy, Reporting and Compliance
The gap between a sustainability commitment and the strategy, governance, data infrastructure and disclosure quality needed to satisfy today's stakeholders is where most organizations find themselves. CSRD is in force. IFRS S1 and S2 are becoming the global baseline. Auditors are reviewing climate disclosures with the same rigour they apply to financial statements. We help you build a strategy that is material and actionable, quantify climate risk with the depth regulators now expect and report with confidence knowing your data, methodology and narrative will hold up.
- Double Materiality Assessment and ESG Strategy Development
- ESG Reporting including IFRS S1 and S2, GRI, CSRD, SFDR, etc
- Climate Risk Assessment, Scenario Analysis and TCFD Alignment
- ESG Ratings Improvement and Assurance Readiness Support

What makes a sustainability consulting firm credible and how is Aranca different?
Credibility in sustainability consulting comes from one thing: whether the work holds up under the scrutiny of investors, regulators and auditors - not just whether it looks good in a report. The firms that earn long-term trust are the ones that build strategies grounded in evidence, produce disclosures that survive third-party assurance, and give clients recommendations that are commercially executable, not just directionally correct.
Aranca sits at the intersection of primary research and strategic advisory. We are not a generalist management consultancy that has added a sustainability practice, nor an environmental firm that has extended into strategy. We bring sector-specific intelligence, quantitative rigour and end-to-end capability across net zero strategy, ESG reporting, green finance, climate technology assessment and sustainability data analytics — in a single practice, without handoffs.
What does a credible net zero roadmap include and how is it different from a net zero target?
A net zero target is a statement of intent. A credible net zero roadmap is the operational and financial plan that makes it real. The difference matters because investors, regulators and supply chain partners are no longer accepting targets without the evidence of how they will be achieved.
A rigorous net zero roadmap includes a complete GHG emissions inventory across Scope 1, 2 and 3, identification and sequencing of the most cost-effective decarbonization levers, science-based interim and long-term targets aligned with SBTi methodology, capital expenditure planning for the transition, and a governance and KPI framework to track progress. It also addresses the sector-specific technology choices and value chain engagement strategies that determine whether decarbonization commitments are executable in practice or aspirational on paper.
What is the difference between ESG reporting and ESG strategy and why does it matter?
ESG reporting is the process of disclosing your organization's sustainability performance against a recognized framework - IFRS S1 and S2, GRI, CSRD, TCFD or SFDR. ESG strategy is the foundation that makes that reporting meaningful: the materiality assessment that identifies what actually matters to your business, the goals and governance structure, and the operational roadmap that drives real performance improvement rather than disclosure compliance.
Organizations that invest in reporting without building the underlying strategy tend to produce disclosures that satisfy the letter of frameworks but fail under investor or auditor scrutiny. As mandatory assurance requirements come into force under CSRD and ISSB, the gap between organizations with genuine ESG strategy and those with reporting-only programmes will become increasingly visible - and increasingly costly.
How does ESG due diligence work in an M&A or private equity transaction?
ESG due diligence in a transaction context involves identifying and quantifying the material sustainability risks embedded in a target before they affect valuation, post-acquisition costs or investor confidence. This means evaluating physical and transition climate risk exposure, Scope 3 liability in the target's supply chain, governance quality and ESG management systems, regulatory compliance across applicable sustainability frameworks, and potential stranded asset risk in transition-exposed sectors.
The output is a risk-rated assessment of ESG materiality with direct implications for valuation and deal structuring, alongside a post-acquisition integration plan. For private equity, this extends across the full investment lifecycle - from ESG screening at deal sourcing through to value creation programmes and exit positioning. As LP demands on ESG performance intensify and regulatory requirements on sustainability disclosure tighten, ESG due diligence has moved from a nice-to-have to a standard part of every serious transaction process.
How do companies approach climate risk assessment under TCFD and IFRS S2?
Climate risk assessment under TCFD and IFRS S2 requires organizations to evaluate both physical risks - the direct impacts of climate change on assets, operations and supply chains such as flooding, extreme heat and water stress — and transition risks, which arise from the policy, technology and market changes associated with moving to a low-carbon economy. Both categories must be assessed across recognized climate scenarios, typically including 1.5°C, 2°C and higher warming pathways, with quantified financial impact analysis rather than narrative-only disclosure.
The most common gap we see is organizations producing scenario narratives that describe climate risks qualitatively but cannot translate them into financial terms - revenue impacts, asset impairment, increased capital expenditure or higher operating costs. Investors and auditors are increasingly requiring this quantification. A climate risk assessment that meets the current standard integrates into enterprise risk management, informs strategic planning, and produces disclosures that are defensible under third-party review.
What types of organizations benefit most from sustainability and climate consulting?
Sustainability consulting delivers the most value to organizations where sustainability decisions carry real financial, regulatory or competitive consequences - which today covers most large organizations across most sectors.
Corporations and industrials typically engage for net zero roadmaps, Scope 3 transparency, mandatory ESG reporting under CSRD or ISSB, and market entry strategy for green economy opportunities. Financial institutions and private equity firms engage for ESG due diligence on transactions, portfolio climate risk management, financed emissions measurement and green finance structuring. Energy companies engage for low-carbon technology strategy across hydrogen, CCUS, renewables and storage. Governments and development finance institutions engage for green finance taxonomy design, climate investment strategy and regulatory framework development. The common thread across all of them is that sustainability has moved from a voluntary commitment to a core business and financial consideration - and the organizations that treat it that way are the ones that get the most from advisory support.
