Module 7 – Climate finance opportunities identification

FIs with a robust climate finance pipeline are well-positioned to attract concessional and blended finance. Global funders increasingly prioritise institutions with a proactive strategy for identifying climate opportunities with measurable real-world impact – particularly where financing helps build resilience within vulnerable communities.

By systematically identifying adaptation, mitigation and transition opportunities at the front line, FIs can develop tailored products such as green credit lines, adaptation-linked loans and climate-resilient insurance. Similarly, demonstrating a clear pipeline of climate-aligned activities signals credibility to stakeholders, enhancing reputations as trusted and forward-looking institutions. This visibility can help attract top talent, deepen relationships with DFIs and strategic investors, and position the organisation as a market leader in sustainable finance.

Getting started with an internal climate finance opportunities checklist

A structured approach to identifying climate finance opportunities can drive long-term business growth. Institutions can integrate this process into their existing systems and workflows in some of the ways set out below, adapting it to their specific strategy, capacity and client base.

• Strategic framing
  Position the climate opportunities pipeline as a core part of the institution’s strategy, resource allocation and growth objectives. Recognise that most FIs are not starting from scratch – they may already be financing activities that support adaptation or mitigation, even if these transactions are not yet labelled as such. For example, products that reduce flood risk or improve crop yields in water-stressed areas may already sit within the portfolio. Identifying and classifying as climate finance can reveal a ‘hidden green’ segment of existing portfolio activity.
• Co-development with front-line staff and prospective clients
  Involve cross-functional teams in designing lookup tables of promising technologies that address key climate-related challenges in the local market. Draw on existing in-house expertise to build an initial opportunity pipeline to help scale dedicated sustainable finance teams. Commercial banks should engage business lines and sustainable finance teams early to address operational concerns and encourage broader adoption. MFIs are encouraged to involve loan officers and field staff who have close knowledge of local communities, their needs and market dynamics.
• Embed into origination
  Integrate the identification of climate finance opportunities at the credit screening phase. Climate risk assessments can also help highlight clients or sectors where such opportunities exist. Early flagging supports pipeline tracking, helping institutions to prioritise high-potential deals, allocate resources effectively, and gather insights for continuous improvement.
• Start simple, then go deeper
  Developing-stage FIs (and MFIs) can start with high-level principles and qualitative categories for identifying climate opportunities. Advanced-stage FIs can increase detail and sophistication gradually as data quality, systems and institutional capacity improve.
• Keep the outcomes decision-useful
  The aim is not to capture every possible opportunity, but to ensure insights are practical, relevant and aligned with client needs. View the climate opportunities checklist as a living document that evolves with the organisation’s goals and changing market landscape.
• Align with key stakeholders
  Refer to national frameworks, such as green taxonomies or nationally determined contributions (NDCs) where available. Use MDB and DFI taxonomies such as BII’s climate finance methodology, Joint MDB principles, or the Green Loan Principles) to align sector classifications and to comply with international climate finance standards.

• Recommendations

  Bottom-up solutions

  Lending officers can identify community-level opportunities such as rainwater harvesting, clean cooking technologies or drought-tolerant seeds, initiatives that deliver high impact for relatively low investment.

  Investor appeal

  MDBs, DFIs and impact investors actively seek MFIs pairing climate intent with reach into underserved markets. Establishing a clear taxonomy strengthens credibility and helps attract funding.

  Start simple

  Begin with the most common hazards or largest client segments. As capacity and data quality improves, opportunities will emerge to test, learn and scale.

  Mine the existing portfolio

  Use loan tracking systems and last-mile staff to identify where climate finance is already embedded, such as drip irrigation or efficient cooling. Build up from what already works.

  Link to livelihoods

  Align climate finance products with MSME income generation, such as solar pumps that provide both efficiency and independence, reinforcing resilience and repayment capacity.

  Leverage partnerships

  Work with local climate solution providers for point-of-sale financing. Find ways to increase access to warranties and after-sales care that reduces risk of product failure and protects repayment quality.

Categorising climate opportunities

In line with best practice, climate opportunities can be grouped into the following high-level categories. The categories may overlap, as some activities contribute to more than one climate objective.

• Climate opportunities for MFIs (MATO)

  • Mitigation-alligned opportunities (M) – Is the project measurably reducing, avoiding or sequestering emissions? If YES, the project is potentially mitigation-aligned.
  • Adaptation-aligned opportunities (A) – Is the project addressing known vulnerabilities to physical risk hazards or contributing to resilience and recovery? If YES, the project is potentially adaptation-aligned.
  • Transition-aligned opportunities (T) – Is the project aimed at decarbonisation within a known high-emitting sector or helping a client make progress towards their transition plan goals? If YES, the project is potentially transition-aligned.
  • Adjacent opportunities (O) – Is the project contributing to other societal benefits, such as the United Nations Sustainable Development Goals (SDGs), or could additional financing help it address such goals? If YES, the project could have the potential for adjacent opportunities.

Design principles and structure for a climate opportunities checklist

1. Categorical branching: each immediate branch is a major climate-relevant intervention, for instance mitigation, adaptation, transition, and adjacent. Therefore, the checklist can be expanded in-depth within each category. In the case of Advanced-stage institutions, the tool can add new categories – such as nature and the just transition – in future.
2. Minimum inputs, maximum insights: each decision point relies on a minimum of data, most likely collected in standard origination processes, such as sector, asset type, asset location, and project purpose.
3. Decision support, not judgment: the tool flags relevant considerations, it does not approve or reject summarily. Relevant employees must always be accountable.
4. Note: Some projects could be flagged as both mitigation and transition-aligned. For example, would a steel production plant exploring decarbonisation options qualify as mitigation or transition-aligned?
   Depending on the client profile and the project details, both flags can be true. The key distinction is that mitigation (M) can be considered more ambitious and only flagged where clients can evidence direct, immediate and quantifiable GHG reductions. By contrast, transition (T) is hard-to-abate, sector-specific and often only demonstrates shorter-term progress towards full Paris alignment.

Creating a climate opportunities lookup table

FIs can use a lookup table to categorise climate opportunities where opportunities tend to be activity-based, for instance linked to the specific use of proceeds. In some cases, client-level checks, such as sustainability certification and external audits, can be used to prove eligibility.

Some examples:

• Sector and industry verticals: comprising energy, transport, agriculture, industry, water, health, and urban environments.
• SDG alignment: comprising healthcare, food security, energy access, biodiversity, water security, resilient livelihoods, social equity, and the just transition.
• Strategic themes: comprising nature-based solutions (NbS), digital technology, financial inclusion, circular economy, clean energy and the built environment.
• Hazard Focus: comprising drought, flood, heatwave, cyclone, pollution and erosion.

These themes can be linked to the following high-level decision tree categories: Mitigation (M), Adaptation (A), Transition (T) and Adjacent Opportunity (O). Examples are as follows:

• Mitigation (M) themes

  • Clean energy generation (solar, wind, geothermal, hydro)
  • Energy efficiency (buildings, industry, appliances)
  • Low-carbon transport and mobility (battery electric vehicles, mass transit, active mobility)
  • Industrial decarbonisation (steel, cement, chemicals, carbon capture, usage and storage)
  • Circular economy and resource efficiency (waste-to-energy, recycling, bioplastics)
  • Nature-based mitigation (reforestation, soil carbon, blue carbon)

• Adaptation (A) themes

  • Climate-resilient agriculture and food systems (drought-resilient seeds, insurance)
  • Water security and coastal protection (desalination, flood barriers, rehabilitated wetlands)
  • Health and social resilience (climate-proof clinics, early warning systems)
  • Resilient infrastructure and cities (flood-proofing, cooling, green and blue infrastructure)
  • Digital climate services (index insurance, mobile hazard alerts)

• Transition (T) themes

  • Sectoral decarbonisation pathways (oil and gas, steel, cement, shipping)
  • Transition finance instruments (sustainability-linked loans and bonds)
  • Just transition (work reskilling, SME decarbonisation, social safeguards)
  • Process emissions abatement (methane leak detection, flaring)

• Adjacent Opportunity (O) themes (additional to all previous)

  • Digital/fintech for climate (ag-tech, insurtech, regtech)
  • Financial inclusion and resilience (micro-insurance, savings, MSME green loans)
  • Social infrastructure (health, education, safety nets with climate lens)
  • Urban upgrades (retrofits, green upgrades in new builds, mobility-as-a-service)
  • SME/community climate solutions (local renewables, nature conservation)

Ultimately, climate opportunity taxonomies and their underlying structures should support rapid intake, sorting and assessment, and be easily expanded as new technologies and solutions emerge.

Guidance 5: Climate opportunities taxonomy

The following guidance offers a practical framework for consistently classifying climate opportunities. It can be used to support decision-making on a case-by-case basis, while ensuring employees remain accountable for final assessments.

Guidance 5 presents a high-level methodology for assessing projects across four categories – mitigation, adaptation, transition and adjacent opportunities – helping to flag potential climate opportunities early in the origination phase with minimal data inputs.

BII’s Climate Investment Playbook covers useful principles, frameworks and case studies for identifying and financing climate opportunities. It offers a holistic picture of climate finance: what it is, why it matters, and how to invest in climate solutions. It addresses all kinds of climate impact – from avoiding GHG emissions to preparing communities to respond to the effects of climate change. It also outlines the steps for originating climate opportunities, integrating climate finance into strategic and operational processes, as well as classifying and assessing impact.
