For clean energy to reach everyone, government can’t just regulate behavior. It has to actively shape credit markets in partnership with the private sector.

Capacity needs:


Access to affordable credit is a necessary condition for an equitable energy transition and an inclusive economy. Markets naturally concentrate capital where risk is low and returns are predictable, leaving low-income communities, rural areas, and smaller projects behind. Well-designed federal policy can change that dynamic by shaping markets—reducing risk, creating incentives, and unlocking private capital so clean technologies reach everyone, everywhere. This paper explores how policy-enabled finance must be part of the toolkit if we are going to drive widespread adoption of clean technologies, and can be summarized as follows: 

The critical role of policy-enabled finance to drive widespread economic opportunity  

Access to affordable credit is not just a financial tool—it is a cornerstone of economic opportunity. It enables families to buy homes, entrepreneurs to launch businesses, and communities to invest in technologies that reduce costs and improve quality of life. Yet, across the United States, access to credit remains deeply uneven. Nearly one in five Americans and entire regions – particularly rural and Tribal communities – are excluded from the financial mainstream, limiting their ability to thrive.

Private-sector financial institutions—banks, private equity firms, and other lenders—are designed to maximize profit. They concentrate on markets where risk is predictable, transaction costs are low, and deals are easy to close. This business model leaves behind borrowers and communities that fall outside these parameters. Without intervention, capital flows toward the familiar and away from the places that need it most.

Public policy can change this dynamic. By creating incentives or mitigating risk, policy can make lending to or investing in underserved markets viable and attractive. These interventions are not distortions — they are strategic investments that unlock economic potential where the market alone cannot, generating economic value and vitality for the direct recipients while yielding positive externalities and public benefit for local communities. And, importantly, these policy interventions act as a critical complement to regulation. Increasing access to credit is often the carrot that can be paired with, or precede, a regulatory stick so that people are not only led to a particular economic intervention, but they are also incentivized and enabled.  

For decades, policy-enabled finance has delivered measurable impact through multiple programs and agencies designed to support local financial institutions – regulated and unregulated, depository and non-depository – that are built to drive economic mobility and local growth. These policies and programs have taken multiple forms, but can generally be put in three categories: 

These tools enjoy broad recognition and bipartisan support because they work. They increase access, availability, and affordability of credit—fueling job creation, housing stability, and economic resilience. Policy-enabled finance is not charity; it is a proven strategy for broad and inclusive economic growth and a key tool for the policy-maker toolkit to support capital investment, project development, and adoption of beneficial technologies in a market-driven context that can increase the effectiveness of a regulatory agenda. 

Most importantly, policy-enabled finance has led to major improvements in wealth-building and quality of life for millions of Americans. The 30-year mortgage was created by the Federal Housing Administration in the 1930s as a response to the Great Depression. Before this intervention, only the very wealthy could afford to buy a home given the high downpayment requirements and short-term loans. Since this policy change, thousands of financial institutions have offered long-term mortgages to millions of Americans who have bought homes that provide safety and security for their families, strong communities, and an opportunity to build wealth through appreciating assets. Broad home ownership is a public good, but until the government created the right policy and regulatory framework for the markets, it was out of reach for the majority of Americans. 

Similarly, the Small Business Administration’s loan guarantee programs started in the 1950s supported financial institutions, including banks and non-bank lenders, in extending credit to small businesses that would otherwise be difficult to serve with affordable credit. These programs have collectively helped millions of small businesses access the credit they need to grow their businesses, create wealth for themselves and their families, provide critical goods and services in their communities, and create a diverse and vibrant local tax base. 

The financial markets, without these types of interventions, are not structured to prioritize access and affordability. Well-designed policy and complementary regulatory interventions have been proven to drive different behaviors in the capital markets that yield real benefits for American families and businesses.  

The role of access to credit in driving an equitable energy transition 

The public and private sectors have spent decades and billions of dollars investing in the development of clean technologies that reduce greenhouse gas emissions, create economic benefits, and deliver a better customer experience. Now that these technologies exist, the challenge is to deploy them for everyone, everywhere. 

The barrier to widespread deployment is that most clean technologies require an upfront investment to yield long-term benefits and savings (i.e., an initial capital expense to reduce ongoing operational expenses) – technologies like solar and battery storage, electric vehicles, electric HVAC and appliances, etc. – which means that people and companies with cash or access to credit are adopting these better technologies while those without access to cash or credit are being left behind. This is yielding an even greater divide – creating economic savings, health benefits, and better technologies for those who can afford them, while leaving dirty, volatile, and increasingly expensive energy sources for the lowest-income communities. 

Many of the federal policy interventions to support deployment of these new technologies to date have been through tax credits. These policies have been very popular, but are not often widely adopted, particularly in rural and lower-income communities, because, (a) they are complex, (b) they often require working with individuals or businesses with large tax liabilities, and (c) they typically come with high transaction costs, making smaller, more distributed projects harder to make work. The energy transition is a huge wave of change, but it is made up of many small component parts – individual buildings, machines, vehicles, grids – so if our policies fail to enable small projects to get done, we will fail to transition quickly and equitably.

To deploy everywhere, households and businesses need credit to offset capital expenses. To expand access to credit, we need supportive clean energy policies that work within and alongside local financial services ecosystems – just like we’ve seen with housing and small businesses. 

Regulation is insufficient to drive widespread adoption 

Pursuing a carbon-free economy is a massive undertaking and, understandably, much of the state and federal government’s toolkit has focused on regulation of people and businesses to drive behavior change – policies like fuel economy standards, pollution restrictions, renewable energy standards, and electrification mandates. This is an important piece of the puzzle – but insufficient to drive broad (and willing) adoption. 

Take, for example, the goal of electrifying heavy-duty trucks in and around port communities. States like California have attempted to set a date at which all new trucks on the registry must be zero-emissions vehicles. Predictably, this mandate was met with a lot of pushback from truck drivers, small operators, and industry associations who struggled to see a path to complying with this regulation without a major increase in cost. 

It wasn’t until the regulation was paired with direct incentives for truck purchases and an attractive and feasible financing package for vehicle acquisition and charging infrastructure that the industry actors started to come around. This has helped change behavior of both buyers and incumbent sellers in the market. 

Policy-enabled finance creates tools – often used in conjunction with other policy mechanisms – that can more effectively meet people where they are with affordable, appropriate, and tailored solutions and can help demonstrate a feasible path to adoption that can help buyers and sellers in these markets adapt accordingly. 

The Greenhouse Gas Reduction Fund as an innovative policy-enabled finance program 

The Greenhouse Gas Reduction Fund (GGRF) is more than an emissions initiative—it is a strategic investment in economic equity and market innovation that took lessons in program design from many sectors and programs of the past. Designed with three core objectives, the program aims to:

GGRF programs, including the National Clean Investment Fund, the Clean Communities Investment Accelerator, and Solar for All, were built to complement other Inflation Reduction Act (IRA) programs by occupying a critical middle ground between grant programs and tax credits. Grant programs provide direct, one-time support for projects and programs that are not financeable (i.e., not generating revenue). Tax credits are put into the market to incentivize private investment for anyone interested in taking advantage but are not typically targeted to any specific project or population. 

GGRF bridges these approaches. It channels capital into markets where funding does not naturally flow in the form of loans and investments, ensuring that clean energy and climate solutions reach every community—but does so in a way that often extends the benefits of the tax credits and incentive programs so that they reach a broader set of projects and communities where the incentive is insufficient to drive adoption. GGRF focuses on increasing access to credit and investment in places that traditional finance overlooks by reducing risk and creating scalable financing structures, empowering local lenders, community organizations, and national financing hubs to deploy resources where they are needed most. Also, because the program makes loans and investments, it recycles capital continuously – akin to a revolving loan fund – so that the work filling gaps in market adoption can continue for decades. 

GGRF’s design was built on a strong foundation of successful direct investment programs for local lenders, such as CDFI Fund awards and USDA programs. What makes it unique is its scale—tens of billions of dollars—and its centralized approach, leveraging national financing hubs to drive systemic change with and through new and existing local financial capillaries (i.e., credit unions, community banks, green banks, and loan funds). This program was not built to drive incremental progress; it is a market-shaping intervention designed to accelerate the clean energy transition while promoting widespread economic growth.

Unfortunately, the program was stopped in its tracks when the Trump administration illegally froze funds already disbursed to awardees, leading to multiple lawsuits to restore funding. Without this disruption, awardees and their partners across the country would be driving direct economic benefits for families and communities across all 50 states. In the first six months of the program, awardees had pipelines of projects and investments that were projected to create over 49,000 jobs, drive $866 million in local economic benefits, save families and businesses $2.7 billion in energy costs, and leverage nearly $17 billion in private capital. The intention and mechanics of the program were working – and working fast – to deliver direct economic, health and environmental benefits for millions of Americans.  

Moving at the speed of trust: Bringing the public and private sectors together for effective implementation 

For a program like the Greenhouse Gas Reduction Fund to succeed, both the private and public sectors need clarity, confidence and accountability. But most importantly, they need a baseline of trust between the parties to support ongoing creative problem solving to implement a new, scaled program with exciting promise and a limited blueprint. 

For the private sector, certainty is paramount. Investors and lenders (and importantly, their lawyers) require clear definitions, consistent requirements, and transparency about the availability of funds, requirements of use, and the ability to forward commit capital to projects and businesses. They need mechanisms to leverage public dollars with private capital and assurances that counterparties will be shielded from political, compliance, and policy risk. Flexibility is equally critical, allowing actors to adapt to rapid market shifts and technological innovations without being constrained by rigid program structures. Understanding these requirements – and the needs of the financial market actors involved – is outside the comfort zone of most government agencies and employees and requires significant experience and capacity building to strengthen this muscle. Nimble thinking is not often associated with government agencies, but in policy-driven financial services, it is paramount. 

At the same time, the public sector has its own requirements which require patience and understanding from the private sector. Policymakers and the EPA, the implementing agency of the GGRF, must ensure that funds are used properly and that Congressional and public oversight is robust. This means designing programs that comply with all laws and regulations while advancing policy priorities. It requires mechanisms for accountability—certifications, reporting, and transparency in how funds flow – along with safeguards against undue influence from purely profit-motivated private actors. Balancing these needs is not optional when managing taxpayer funds; it is the foundation for building trust and ensuring that the program delivers on its promise of reducing emissions, benefiting communities, and transforming markets. 

Implementation requires striking the balance between the needs of the private and public actors; this was difficult and time consuming for both the federal employees and for us as private recipients. There was pressure to deploy quickly to demonstrate impact and the value of the program, but it took a long time to get contracts signed and funds in the market because of the many requirements of the public and private parties involved. We speak different languages, are solving for different constraints, and work in drastically different environments – all which led to complexity and delays. 

Internal EPA requirements and federal crosscutters (i.e., federal requirements from other related laws that applied to this program) increased time to market and transaction costs. Many of these requirements came with high-level policy objectives without the ability to get to a level of detail required for capital deployment. 

For example, two of the major policy crosscutters were the Davis Bacon and Related Acts (DBRA) requirements around labor and workforce, and the Build America Buy America (BABA) requirements for equipment manufacturing and component parts. While the agency and private awardees were aligned at a high level on policy intention – good-paying jobs and domestically-manufactured goods – down streaming these requirements to borrowers and projects required significantly more detail and nuance than was available to the agency, adding weeks and months onto implementation and frustration among private counterparties. 

Clear expectations up front on how to manage the trade-offs – policy priorities versus capital deployment – could have helped create a high-level framework for implementation, which was a one-by-one review of use cases to determine feasibility and applicability. This added complexity and friction to the process without driving outsized results. 

More requirements and complexity led to slower, more costly deployment, which meant fewer communities would benefit from the program’s goals of cutting emissions, creating jobs, and cutting household and business costs. 

Another key feature of the program for the National Clean Investment Fund and Clean Communities Investment Accelerator was the ability for the federal government to leverage a Financial Agent to administer the funds. This arrangement was developed between the EPA and Treasury, leveraging a long-standing practice of the Treasury Department of contracting with external banks to provide financial services that were hard for the government to provide directly. This was particularly important for the National Clean Investment Fund program because the disbursement of funds into awardee accounts enabled the awardees to meet a core statutory requirement to leverage funds with private capital. Without this function, the cash would not be available on the balance sheet of the awardees and would be difficult to leverage with private investment. 

Lastly, the reporting requirements for the program were complex, making it hard to provide clarity on what data collection was required for early transactions. Again, both parties recognized the importance of transparent data collection and dissemination but implementing that intent in practice was time consuming. A simple, standardized framework to get started that could evolve over time would have helped reduce uncertainty and supported faster deployment. 

Altogether, the cross-sector translation – finding common ground between two disparate worlds – added many months onto the process of getting the program to the market which, in the current political climate, was time not spent doing the important work to educate a broad set of stakeholders on the program’s promise, potential, and purpose. A lot of this complexity could have been reduced by developing a baseline of trust between the parties through the application and award process, complemented by a common goal to improve program implementation over time. 

Strange bedfellows create weak alliances 

In addition to the programmatic elements of translation, the actors involved in implementing direct investment strategies tend to be unknown entities to government agencies and Congress. Even though many of the implementing organizations – the “awardees” – have been around for decades doing similar work, there were weak ties with Congress, federal agencies, and other related stakeholders. Similarly, there was a lack of understanding of the role that nonprofit and community-based financial organizations play in addressing market gaps. This mutual lack of understanding and engagement leaves room for misunderstanding, distrust or generalizations that can hinder the ability to make collective progress. 

Within the agency, this was a new program type for the EPA, so requirements and design process took many months before anything was shared publicly. The Notice of Funding Opportunity was released nearly a year after the legislation was signed. 

The unique form and function of the program and limited direct engagement with lawmakers and other stakeholders about the program left a vacuum of information, which led to skepticism and confusion. Because the funds were provided to awardees as grants, many interpreted this as just another grant program – a large federal spending package that would lead to “handouts” – instead of what it was, the federal government seeding a sustainable fund with “equity” that would be lent out, returned, and reinvested in perpetuity. For example, here is the Wall Street Journal editorial page,and later, the EPA press release conflating investments with “handouts”: 

Imagine if Republicans gave the Trump Administration tens of billions of dollars to dole out to right-wing groups to sprinkle around to favored businesses. That’s what Democrats did in the Inflation Reduction Act (IRA). The Trump team’s effort to break up this spending racket has led to a court brawl, which could be educational.

The fact that this policy structure and the private sector entities charged with implementing it were relative strangers led to confusion and delay during a period that could have been spent on outreach, engagement, and education. Without that broad base of support, the program unnecessarily became a political punching bag.

To mitigate this risk going forward, there needs to be greater investment in relationship building, education, stakeholder engagement and capacity building within and among the implementing partners across all relevant government actors and their private sector counterparts, especially after award selections are made. This connective tissue would go a long way in creating a baseline of common understanding of the policy objectives, program design, and implementation partners involved so all parties are aligned on strategic intent and path forward. 

Making policy-enabled finance programs work in the future 

If we agree that policy-enabled finance is essential to drive the energy transition and deliver broad benefits, the next step is asking the right questions about how to design these interventions for success, drawing lessons from the GGRF and other related programs.

First, what mechanisms should we use, and what are the trade-offs for each? Federally supported direct investment programs, such as managed funds, can deploy capital quickly and target underserved markets, but they require strong governance, thoughtful program design, and radical transparency, otherwise they are susceptible to the “slush fund” narrative or similar risks (i.e. conflicts of interest and political favors). 

Tax credits and incentives have proven effective in attracting private investment, yet they often favor actors with existing tax liability and can leave smaller players behind. Guarantees reduce risk for lenders and unlock private capital, but they demand careful structuring to avoid moral hazard and can struggle to reach communities that are truly under-resourced. 

Despite the many pitfalls of direct investment programs, they address a challenge that has plagued many of the more distributed policies: centralization and market making. Often in an attempt to let a thousand flowers bloom, policymakers underestimate the need for centralized or regional infrastructure to help with asset aggregation, data collection, product standardization, and scaled capital access. This yields local infrastructure that is sub-scale, inefficient, and unable to access the capital markets for private leverage – too small to truly shape markets.

While the GGRF’s future is uncertain given pending litigation, its purpose and role as a set of centralized financial institutions within the broader community-based financial ecosystem is critical – and needs to be more broadly understood as policymakers set future priorities. 

Second, should government manage funds and programs internally or partner with external experts? Internal management within an agency offers control and accountability but can strain agency capacity and impede the ability to be an active market participant. It is also difficult to attract the right talent within the government’s pay scale, leading to an inability to recruit and high turnover. This model has been attempted through programs like the Department of Energy’s Loan Programs Office (LPO), but even that market-based program has been slower to execute, delaying critical infrastructure and technology investments by months, if not years.   

On the other hand, external management brings specialized expertise and market agility, yet it raises questions about oversight and influence. No matter who the private party is, there is skepticism around the use of funds, their personal or professional gain, and their intentions with taxpayer money. In our deeply politicized world, this puts a target on the leaders of these organizations that may limit who is willing to play this role. 

Quasi-public Structures

Despite the challenges, on balance it seems that internal agency management or a quasi-public structure is the most feasible path. Internal management pushes the boundaries of public agency function but goes a long way to build trust and accountability. Quasi-public structures seem to be a good compromise when feasible. Other countries have figured out how to manage these programs within a government or quasi-government agency (see the Clean Energy Finance Corporation and Reconstruction Finance Corporation, both in Australia). We can too. 

At the federal level, credit programs should be managed by agencies with the skills and capacities to hold an investment function, like the Department of Energy or the Treasury Department, and leverage lessons learned from programs like DOE’s LPO and EPA’s GGRF to structure new entities. Or – like many of the state and local green banks have done – create quasi-public entities that have public sector governance and appropriations but otherwise operate independently as financial institutions with their own balance sheets, bonding authority, and staffing structure. 

Lastly, if public-private partnerships are preferred, who should the government work with to implement policies meant to expand access to capital and credit? Nonprofit financial institutions often prioritize mission, community impact and are willing to arrange complex financings that require a higher touch approach but often lack scale and institutional capital access. For-profit firms bring scale and expertise but often find it hard to manage a government program with a mindset or culture that differs from their typical profit-maximization frameworks. 

Depository institutions such as banks offer stability and regulatory oversight, whereas non-depositories can innovate more freely to reach the hardest to serve communities. Regulated entities provide robust and trusted infrastructure and controls, but unregulated actors may move faster and can be more creative in supporting traditionally under-resourced opportunities. Specialty firms bring deep sector or asset-class knowledge, while generalists offer broad reach and experience in managing across asset classes. 

To identify the optimal path, it is helpful to look to existing programs for lessons. The U.S. Treasury’s Emergency Capital Investment Program (ECIP) demonstrates how direct investment into regulated depository institutions can mobilize significant capital for underserved communities through an existing financial ecosystem. The Loan Programs Office shows what internal management can achieve for large-scale projects. Tax credit programs like the New Markets Tax Credit (NMTC) and Investment Tax Credit (ITC)/Production Tax Credit (PTC) illustrate how incentives can transform markets, while guarantee programs such as the U.S. Department of the Treasury’s Community Development Financial Institutions Fund (CDFI) Fund Bond Guarantee and SBA 7(a) and 504 guarantees highlight the power of risk mitigation in activating and standardizing products to support secondary market access. These precedents offer valuable insights as we design future policies to accelerate a broadly beneficial energy transition.

Educating policymakers to build trust in the community finance ecosystem

Regardless of path forward, one thing remains critical – building better relationships between policymakers and the community finance industry, including community banks, credit unions, loan funds, and green banks. These are the boots-on-the-ground organizations that share a mission with many policymakers to expand economic opportunity and broaden access to capital and credit. And they are often the organizations navigating multiple public products and programs to bring affordable, quality financial services to communities. 

The challenge is that most advocacy and educational work for these organizations has been siloed – there are groups representing credit unions big and small, those representing housing lenders, loan funds, green banks, and community banks. The disaggregation of these efforts has diluted the potential for policymakers to look at this ecosystem as a whole to determine how best to leverage it for public good. This is not to say that each of these individual groups does not have a role to play for their members – they all have different needs and requirements and deserve representation. But the broader industry would benefit from collaboration across these organizations to create a mechanism for these institutions to help with outreach, advocacy and education around policy-enabled finance overall. This would bring a strong and powerful group of actors together for a higher collective purpose and, ideally, create a large and diverse constituency with common goals. 

State and local governments stepping up  

In the near-term, the absence of federal support for clean technology deployment through policy-enabled finance creates an enormous opportunity for state and local governments to step up and push forward. Hundreds of local financial institutions were doing work to prepare for the delivery of GGRF funds to and through local projects and businesses to drive broader adoption of clean technologies. These organizations continue to have the skillsets, capacity, and pipeline to finance these projects – but need access to flexible and affordable capital to do so. 

State funding efforts could mirror the program and product design of the GGRF to get deals done locally, working with one or more of the constellation of financial institutions preparing to deploy federal funds. Just because the GGRF’s programs were cut short, it doesn’t mean that the infrastructure and learnings generated should go to waste – if there are public institutions willing to commit capital, there should be many financial institutions across the country ready to put it to good use. 

Conclusion 

If our shared goal is an equitable, rapid energy transition, policy must do more than regulate — it must enable finance and focus on deployment, or getting great projects done. The Greenhouse Gas Reduction Fund showed both the promise and the pitfalls of large-scale, policy-enabled finance: when designed and governed well, these tools can unlock private capital, deliver measurable local benefits, and sustain long-term market transformation. When implementation gaps and weak relationships persist, even well-intentioned programs become politically vulnerable and ripe for attack. To make these programs successful within our current political context, future efforts should prioritize clear governance, cross-sector capacity, and sustained stakeholder engagement so public dollars can catalyze private investment that reaches every community.
