The Lab has launched six financial instruments targeting blue carbon, sustainable agriculture, sustainable cities, and energy access. These instruments, which follow a seven-month design and stress-testing period, aim to mobilize significant investment for sustainable development. Key projects include mangrove restoration in the Philippines, blockchain-based crop insurance in Kenya, and solar securitization in Rwanda.

The Distributed Energy for Social Housing (DESH) fund is a third-party ownership and rental model designed to overcome financial barriers for low-income Brazilian households accessing solar energy. By funding 100% of projects and eliminating upfront costs and interest rates for tenants, the instrument aims to provide energy at 10-20% below standard utility rates. A 5 MW pilot involving five 1 MW plants in state capitals is projected to require US$ 6 million in investment, serving 2,900 households and mitigating 105,000 tons of carbon emissions. The fund utilizes a dual-class structure with a first-loss tranche for concessional capital and a senior tranche for commercial investors, with a long-term goal of mobilizing US$ 1.1 billion to reach over 677,000 households within 12 years.

The Battery Subscription Facility is a special purpose vehicle (SPV) designed to lower the high upfront cost of electric buses in India—which are 1.5 to 2 times more expensive than diesel buses—by providing batteries on a subscription basis. By separating the cost of the battery from the vehicle, the facility aims to reduce upfront capital expenditures for bus operators by 40-50%. The implementation is structured in three phases: a pilot phase (10-30 buses), a catalytic phase (1,000 buses), and a scale-up phase (up to 10,000 buses). The model relies on a tripartite agreement between the bus operator, the Facility, and a local financial institution (LFI), with long-term debt (8-10 years) sourced from development finance institutions (DFIs) to match the cash flow profile of electric bus operations. The facility primarily targets the corporate bus segment to minimize counterparty risk and simplify charging infrastructure installation.

The briefing outlines a sustainable finance instrument designed to transition Indian auto-rickshaw drivers from conventional vehicles to electric ones. By providing 100% debt financing, eliminating collateral requirements, and offering lower interest rates (22%-24% per annum), the instrument aims to replace the current rental model and predatory informal loans. The proposed NBFC structure will pool equity, commercial debt, and concessional capital, utilizing a community-driven loan appraisal and collection system to mitigate default risks. A pilot project targeting 500 vehicles in Bengaluru, Chennai, and Chitradurga is planned to demonstrate the model's viability and environmental impact, with a long-term goal of capturing 5% of the Indian market to avoid 9 million tons of carbon emissions.

The Green Aggregation Tech Enterprise (GATE) is a proposed guarantee facility designed to mitigate demand and payment risks for mini-grids in Sub-Saharan Africa. By guaranteeing a baseline level of revenue, GATE aims to transform mini-grids into a bankable asset class, shifting their financing from donor grants to private debt. The instrument will be piloted in Nigeria, Kenya, Zambia, and the DRC, with a phased implementation pathway moving from a proof-of-concept (2018-2019) to full commercialization by 2028-2030. Financial modelling suggests that at scale, GATE can be sustainable and catalytic, potentially mobilizing US$ 1.725 billion in private investment by 2030 and providing electricity to millions of households and businesses.

The report proposes the PAYS for Clean Transport instrument to address the high upfront costs of electric buses, which can be up to 40% higher than diesel alternatives. Under this model, utilities invest in batteries and charging infrastructure and recover costs through a fixed charge on the bus service provider's (BSP) electric bill. This approach shifts capital expenditure from the BSP's balance sheet to a monthly operating expense, reducing the need for grants and leveraging private finance. Modeling for a 100-bus fleet in Santiago, Chile, indicates that PAYS can make electric buses cheaper than diesel over their lifecycle and leverage over 70 dollars of private investment for every grant dollar provided.

The Responsible Commodities Facility (RCF) is a proposed debt fund designed to halt agricultural expansion into the Brazilian Cerrado by providing low-interest loans to farmers who produce soy and corn on degraded lands. The facility aims to raise US$ 300 million through green bonds to provide crop financing and land restoration loans, utilizing blockchain for traceability and a dedicated exchange to link producers with international sustainable buyers. Over 10 years, the RCF targets the restoration of 1.2 million hectares of land and the avoidance of 55 million tonnes of carbon emissions.

The Rooftop Solar Accelerator (RSA), implemented by Peacock Solar, aims to overcome barriers to residential solar adoption in India—such as high upfront costs and operational inefficiencies—by using a solar leasing model, standardized product offerings, and advanced data analytics. The instrument targets smaller Indian cities, starting with a test phase in Kota, and seeks a mix of commercial debt, equity, and philanthropic capital to scale. If replicated, the model could potentially mobilize US$ 380 million and abate 640,000 tons of CO2 by 2022.

The Smallholder Forestry Vehicle (SFV) is a proposed financial instrument designed to scale smallholder forestry in Africa by aggregating tree production contracts into a Special Purpose Vehicle (SPV). By separating the high-risk establishment and harvest phases from the lower-risk growth phase, the SFV aims to lower the cost of capital and attract institutional investors. A proof-of-concept facility targeting US$ 35 million in coastal Kenya is proposed to restore 5,000 hectares of degraded land and provide climate-resilient savings to over 16,000 households. The analysis suggests that with concessional debt and first-loss equity, the vehicle can achieve a gross internal rate of return (IRR) of 11.1%. Long-term goals include expanding into Greater East Africa and mobilizing up to US$ 8.5 billion in initial investment to meet regional land restoration targets.

The Smallholder Forestry Vehicle is a proposed financial instrument designed to enable forestry companies in Africa to access long-term, low-cost finance by aggregating smallholder tree production contracts into a Special Purpose Vehicle (SPV). By separating the high-risk establishment and harvest phases from the lower-risk growth phase, the vehicle aims to attract institutional investors, including pension funds and impact investors. A proof-of-concept facility targeting US$ 35 million in coastal Kenya is proposed to demonstrate risk-adjusted returns and climate resilience benefits, such as land restoration and diversified income for farmers. The analysis suggests that the instrument can leverage significant private capital and be replicated across other East African nations to meet land restoration targets.

The Socio-Climate Benefits Fund (SCBF) is a proposed investment vehicle designed to combat small-scale deforestation in the Brazilian Amazon. It operates by funding a 'New Company' that provides upfront capital, technical training, and market access to smallholders who implement sustainable agroforestry systems (SAFs) on their land. The model utilizes a vertical integration approach, similar to poultry or swine supply chains, where the New Company and smallholders co-own the harvest. The initial pilot targets the state of Acre, aiming to restore 12,000 hectares of forest and engage up to 3,000 properties over a decade. The fund seeks a mix of grants, concessional debt, and equity to overcome barriers such as lack of long-term finance and market access for small-scale farmers.

The briefing proposes the use of Solar Investment Trusts (SEITs), structured as Infrastructure Investment Trusts (InvITs), to address financing barriers for small-scale rooftop solar projects in India. By pooling assets, SEITs aim to attract institutional investors, reduce the cost of equity by 300-350 basis points, and potentially mobilize USD 1 billion for the rooftop solar sector within five years. However, the document identifies significant barriers to immediate implementation, including SEBI's minimum asset value requirement of INR 500 crore and strict leverage limits of 49%, which currently exceed the capacity of even the largest Indian rooftop solar developers.

Sustainable Energy Bonds (SEBs) are proposed as a mechanism to bridge the debt financing gap for small-scale sustainable energy projects in India. By aggregating small projects through a Non-Banking Finance Company (NBFC), SEBs reduce transaction costs and provide standardized impact reporting to attract impact investors. The analysis suggests that initial issuances, such as a proposed USD 5 million pilot by cKers Finance, require approximately 4% in public finance support—covering credit enhancement and monitoring, reporting, and verification (MRV) costs—to maintain competitive lending rates of around 10% for project developers.

The Matchmaker Service is a two-part instrument consisting of a subscription-based platform to match investors with city-level climate projects and a project preparation facility to improve project bankability. It specifically targets the financing gap for urban climate infrastructure in India, where municipalities often lack the capacity to create commercially viable projects and the creditworthiness to attract private capital. The report proposes a pilot project for electric bus fleets in Srinagar, Jammu and Kashmir, utilizing a blended finance model via a Special Purpose Vehicle (SPV) to reduce the high cost of capital associated with private operators.

The Climate Smart Cattle Ranching (CSCR) initiative proposes a 'New Company' to address barriers to sustainable beef production in Brazil, specifically targeting mid-sized ranchers in the Amazon who lack formal land titles. The model uses a blended finance approach—initially through a Participations Investment Fund (FIP) involving grants, concessional debt, and impact equity—to co-invest in pasture restoration and the adoption of Embrapa’s Good Agricultural Practices (GAP). By providing long-term capital (up to 10 years) and continuous technical assistance, the instrument aims to increase productivity from 0.5-0.7 to up to 4 Animal Units per hectare, potentially reducing emissions intensity by 90-95% per kg of beef. The strategy includes a phase-out of concessional capital in favor of commercial investment via a Credits’ Rights Investment Fund (FIDC) once a track record of receivables from deforestation-free beef off-take agreements is established.

The document proposes the Green FIDC, a specialized securitization vehicle that transforms risky greenfield projects into bankable assets for institutional investors. By utilizing a two-stage process—initial development finance followed by refinancing through senior shares in the Brazilian capital markets—the instrument aims to reduce reliance on the Brazilian National Development Bank (BNDES) and lower the cost of capital for renewable energy and energy efficiency initiatives. The analysis highlights two pilot opportunities: a 90 MW solar PV project in Ceará and a municipal street lighting LED retrofit in Rio de Janeiro. Financial modeling suggests the instrument is commercially viable, with the potential to leverage USD 1 billion in investment and avoid 10 million tons of CO2 if scaled.

Loans4SME is a proposed technology-driven peer-to-peer (P2P) lending platform designed to bridge the USD 44 billion debt financing gap for Indian SMEs in the renewable energy and energy efficiency sectors. By connecting borrowers directly with high-net-worth individuals and institutional investors, the platform aims to bypass traditional banking barriers such as stringent collateral requirements and slow sanction times. The instrument features a proprietary credit scoring algorithm that incorporates forward-looking financials and alternative data, which the report claims is more robust than traditional bank models. The analysis estimates that a 5% market share could mobilize USD 2.2 billion in private capital and add 800 MW of solar rooftop capacity by 2022. While deemed highly actionable with a feasibility score of 2.67/3, the report identifies regulatory uncertainty as a high-risk challenge since P2P lending remained unregulated in India at the time of publication.

The report outlines a financing facility to address debt capital shortages for India's rooftop solar sector, specifically targeting commercial and industrial segments. It proposes a mechanism to bundle small projects into a warehouse line of credit, which is then refinanced via asset-backed securities (ABS) to attract institutional investors. The facility aims to lower debt costs by 0.5-3.5% and add 500MW of capacity by 2022.

The report examines Energy Savings Insurance (ESI), an instrument developed by the Inter-American Development Bank and BASE to unlock energy efficiency investments for SMEs by insuring against the risk that projected energy savings are not met. ESI can absorb up to 80% of underperformance risk and is being piloted or replicated across several countries, including Mexico, Colombia, and El Salvador. If scaled globally, the instrument is estimated to drive USD 10-100 billion in investment and reduce annual emissions by 27-234 MtCO2 by 2030.

The Agricultural Supply Chain Adaptation Facility (ASCAF) is a proposed financing mechanism to help small- and medium-sized farmers in the Latin America and Caribbean region invest in climate-resilient agricultural measures. By using donor-backed first-loss guarantees and technical assistance provided through Multilateral Development Banks (MDBs), ASCAF aims to enable agribusiness corporations to extend medium- to long-term loans (5-7 years) to their suppliers. The facility targets 'tight' value chains for high-value crops like coffee, sugarcane, and cocoa to reduce credit risks and capacity gaps. If scaled, the facility could potentially protect or increase the revenues of 63,000 to 420,000 farming households by 2030, with a total market investment potential estimated between USD 2.5 billion and USD 4.4 billion for four sample crops.
