Assessing Sources of Climate Finance

About this Opportunity

Financing the implementation of NDCs will require the use of multiple financial instruments and the strategic use of limited public finance to mobilize domestic and international private sector investments at scale. Building on the assessment and prioritization of investments, it is beneficial to conduct an in-depth evaluation of the landscape of financial sources and instruments available in the country and how to strategically finance the different NDC investment needs.

Common Financial Instruments

Some of the most common financial instruments available at the international and domestic level (with grants primarily from public sector and philanthropies, loans primarily from development finance institutions [DFIs], international finance institutions [IFIs] and commercial banks, and equity primarily from private businesses and state-owned entities [SOEs]) to finance the development and implementation of NDCs are summarized below (see A, B, C and D in table). This information draws in part from the Global Landscape of Climate-Finance 2023 (Climate Policy Initiative, 2023). Additionally, taxes and subsidies (see E and F) and certain de-risking and catalytic instruments, in addition to grants (see G, H and J), as well as carbon offsetting (see I), have been included to further diversify and blend funding sources and explore new avenues for financing.

Example of Financial InstrumentSummaryDomestic/ International
A. GrantsTransfers made in cash, goods or services for which no repayment is required. These are often provided by governments, international organizations, or philanthropic institutions to support various climate-related projects.International
B. Debt (e.g., loans)Transfers made in cash for which repayment is required. Concessional loans have more favorable terms and conditions than standard market loans. Loans are issued by governments, international financial institutions, or commercial banks to finance climate projects, infrastructure, or business activities.Domestic/International
C. Debt (e.g., bonds)Debt securities that involve transfer of funds from an investor to a borrower — typically, governments or corporations. “Green bonds” are specifically issued to finance climate-related or environmental projects. Governments and corporations issue bonds to raise capital for various projects contributing to environmental sustainability. (Source: Climate Bonds Initiative)   Bonds can also be issued more specifically to finance green infrastructure projects such as renewable energy installations, sustainable transportation systems, or energy-efficient buildings. Such “green infrastructure bonds” provide capital for climate-resilient infrastructure development and mitigation projects worldwide. (Source: Climate Development and Knowledge Network (CDKN))Domestic/International
D. EquityOwnership shares in a company, providing ownership interest to shareholders. “Green equity” can be raised to finance environmentally sustainable initiatives or projects. Investors purchase shares in companies to support sustainable practices, renewable energy projects, or climate adaptation efforts. (Source: Heinrich-Böll-Stiftung)Domestic/International
E. Taxes (e.g., green taxes or carbon taxes)Mandatory contributions levied by governments to finance activities and public services. “Green taxes” or “carbon taxes” aim to increase the cost of certain activities such as pollution or energy use, encouraging mitigation efforts and funding climate-related projects and initiatives. (Source: Center for Climate and Energy Solutions (C2ES)Domestic
F. Subsidies (e.g., green subsidies)Financial assistance provided by governments to reduce the cost of activities or goods for organizations or individuals. “Green subsidies” aim to support environmentally friendly practices or products, stimulating adoption and investment in climate-friendly technologies and initiatives. (Source: OECD)Domestic
G. De-risking instruments (e.g., guarantees)    Risk-mitigation instruments providing credit enhancement to cover potential losses, making investments more attractive. Government or international guarantees facilitate access to commercial debt for climate projects, supporting investments aligned with climate goals and NDCs. (Source: World Resources Institute (WRI))Domestic/International
H. De-risking instruments (e.g., insurance)Financial instruments transferring climate-related risks from insured parties to insurance companies. Insurance mechanisms help manage risks associated with climate change impacts, such as extreme weather events or natural disasters, providing financial protection and support for adaptation measures. (Source: United Nations Development Programme)Domestic/International
I. Carbon offsettingCarbon trading mechanisms allowing individuals or companies to invest in projects reducing or capturing greenhouse gas emissions to offset their own emissions. Carbon offset projects contribute to global emission reduction efforts and support mitigation activities in various regions and sectors. (Source: United Nations Framework Convention on Climate Change)International
J. Results-based financing (Performance-based payments) and incentivesFunding provided based on the achievement of predetermined results, incentivizing performance-based action for emissions reductions or increased resilience to climate change. Results-based financing mechanisms support projects with measurable impacts, encouraging accountability and effectiveness in climate finance allocation.

The following strategies could help to implement this Opportunity:

The following strategies and enablers can help to facilitate understanding the landscape of available financial options:

Enhancing understanding of the climate finance landscape for NDCs

Developing a strategy that provides a clear and accessible understanding of climate finance could include signposting to tools and guides aimed at demystifying general NDC financing, such as understanding the landscape, defining processes and requirements, and the role of investment plans to access those funds. This landscape should also consider domestic sources, as relying solely on international sources may not fully address the diverse financing needs within a country, and tapping into domestic resources can provide additional stability and sustainability to climate finance initiatives.

Maximizing financial opportunities for NDC implementation

Unlocking the necessary finance for subsequent implementation of the NDC requires careful planning and strategic utilization of available financial instruments and sources. Key opportunities include:

  • Diversifying funding sources. Relying on a single source of funding for NDC implementation can pose risks. Exploring a diverse range of domestic and international funding sources, including grants, loans, equity investments, bilateral finance and blended finance solutions can spread risk and ensure financial stability.
  • Aligning funding with NDC priorities. Ensuring that the chosen financial instruments align with the conditional and unconditional priorities outlined in the NDC will increase the likelihood of successful funding. For example, if the NDC emphasizes renewable energy projects, consider accessing funds earmarked for green initiatives, such as green bonds or grants.
  • Leveraging concessional financing. Concessional loans, which offer more favorable terms and conditions than standard market loans, can be a valuable resource for NDC implementation. Governments could explore opportunities to access concessional financing from multilateral development banks and other financial institutions to reduce borrowing costs and enhance financial sustainability.
  • Enhancing coordination and collaboration. Coordinating with relevant stakeholders, including international organizations, development banks, private sector entities, and civil society organizations, to leverage their expertise, resources, and networks. Collaboration can facilitate access to financing opportunities, promote knowledge sharing, and foster innovation in NDC implementation.
  • Promoting transparency and accountability. Establishing robust mechanisms for monitoring, reporting, and evaluating the use of funds allocated for NDC implementation. Transparency and accountability in financial management are important for building trust among stakeholders, attracting additional investment, and demonstrating progress toward NDC targets.

Country Examples

Tajikistan leveraged resources from the Green Climate Fund (GCF) and key partners to strengthen the capacity of its National Designated Authority (NDA). The project built capacity within the NDA to engage key stakeholders to access and deploy climate finance in Tajikistan, as well as update its NDA website and develop communication and knowledge products to be disseminated on a platform to improve Tajikistan’s ability to access and deploy climate finance.
