The Connecticut Green Bank is the nation’s first green bank.* Established by the Connecticut General Assembly on July 1, 2011 as a part of Public Act 11-80, Connecticut Green Bank supports the Governor’s and Legislature’s energy strategy to achieve cleaner, affordable, and reliable sources of energy while creating jobs and supporting local economic development. The Connecticut Green Bank evolved from the Connecticut Clean Energy Fund (CCEF) and the Clean Energy Finance and Investment Authority (CEFIA), which was given a broader mandate in 2011 to become the Connecticut Green Bank.
The Green Bank’s vision is a planet protected by the love of humanity and its mission is to confront climate change by increasing and accelerating investment into Connecticut’s green economy to create more resilient, healthier, and equitable communities.
Our green bank model upended the government subsidy-driven approach to clean energy by working with private-sector investors to create low-cost, long-term sustainable financing to maximize the use of public funds. We continue to innovate, educate and activate to accelerate the growth of green energy measures in the residential (single and multifamily), commercial, industrial, institutional and infrastructure sectors.
The model works. We are deploying more clean energy more quickly and efficiently than ever. Since its inception, the Connecticut Green Bank and its private investment partners have deployed over $3.11 billion in capital for clean energy projects across the state. Projects recorded through FY 2025 show that for every $1 of public funds committed by the Green Bank that an additional $6.70 in private investment occurred in the economy.

New offering supports Connecticut small business energy efficiency projects, while future Note will allow community investors to back Branford’s electric school bus fleet and bidirectional recharging infrastructure.
HARTFORD, Conn. — October 6, 2026 — The Connecticut Green Bank today announced the opening of its 18th Green Liberty Note offering, providing residents and investors nationwide with an opportunity to earn a return while supporting clean energy investments in Connecticut. The offering will finance energy efficiency improvements through Eversource’s Small Business Energy Advantage (SBEA) program, helping small businesses reduce energy costs and improve performance.
The launch follows the successful close of the Green Bank's 17th Green Liberty Note offering and continues the momentum of a program that has attracted more than $5 million in investments since its launch in 2021. The Green Liberty Note program enables individuals to invest directly in Connecticut’s green economy with a minimum investment of $100 through a partnership with Honeycomb Credit.
The 18th Green Liberty Note offering also features an increased interest rate, providing an attractive opportunity for both new and returning investors. Current noteholders who invested in the 14th, 15th, 16th, or 17th Green Liberty Note offering are eligible for an interest-rate boost when participating in the current offering.
Looking Ahead: Branford Electric School Bus Investment Opportunity
In addition to the current offering, the Connecticut Green Bank announced plans for a unique project- specific Green Liberty Note later this fall that will support the electrification of the Town of Branford’s entire school bus fleet, including bidirectional charging infrastructure – the first of its kind in New England. The project was developed in partnership with the Town of Branford, Branford Public Schools, and school transportation provider Zum. The electric fleet began operating earlier this fall, helping
provide cleaner transportation for students while reducing emissions in the community.
The upcoming offering will give investors the opportunity to directly support the school bus electrification project and further connect their investments with tangible green energy infrastructure in Connecticut. Pursuant to Public Act 26-63, Connecticut school districts must deploy 90% zero-emission school bus fleets by 2040. Branford Public Schools will be the first school district in Connecticut to meet this milestone. According to the Green Bank's investment webpage, investors will also have the option to share a portion or all of their interest earnings with a local partner organization.
“Green Liberty Notes have always connected investors with meaningful projects in their communities with strong demand from Connecticut residents and people across the country since 2021 interested in investing alongside us," said Bryan Garcia, President and CEO of the Connecticut Green Bank. "The upcoming Branford offering will provide a compelling example of how local investments in our green economy can help accelerate innovative solutions that benefit students, families, and the environment.”
The Connecticut Green Bank encourages individuals interested in the open 18th offering or the upcoming offering to visit www.greenlibertynotes.com to access more information, see the interest rate offer, or sign up for notifications.
On the back of the Connecticut Green Bank’s 16th Green Liberty Notes offering going live on Honeycomb Credit’s platform, both organizations announce a new agreement that increases future opportunities for participation in the green economy by residents.
HARTFORD, Conn. (April 14, 2024) – The Connecticut Green Bank, the nation’s first state-level green bank, and Honeycomb Credit, the nation’s leading debt-based crowdfunding platform, today announced a new agreement that continues their successful partnership and opens the door for future expansion that will allow more Connecticut residents to participate in the green economy. The announcement comes as the Green Bank’s sixteenth Green Liberty Note offering opens in celebration of Earth Month, allowing investors to support a series of offerings that has already raised more than $3 million for Connecticut’s green economy. More than half of all investors have been Connecticut residents, and more than 60% of investments have been $1,000 or less.
“The Connecticut Green Bank has always believed that confronting climate change requires public participation,” said Bryan Garcia, President and CEO, Connecticut Green Bank. “This agreement strengthens our ability to mobilize investment from Connecticut’s residents directly into projects that benefit our communities, including reducing energy costs and creating jobs. We’re not just building a greener Connecticut – we’re building a coalition of climate investors at the local level to help get us there.”
A Foundation Fifteen Raises in the Making
The announcement builds on one of the most successful community investment programs in the country and demonstrates that everyday investors – not just institutional ones – will show up for climate. To date, the Green Liberty Notes offerings have all supported Eversource’s Small Business Energy Advantage (SBEA) program, which enables the state’s small businesses to reduce their energy costs through efficiency upgrades and zero-interest on bill financing. SBEA offers a no-cost, no-obligation energy assessment to small businesses, providing a one-stop service that combines easy access to energy efficiency measures as well as incentives and payment plans.
Now, given the infrastructure, investor community, and institutional trust built across 15 successful raises, the Green Bank and Honeycomb Credit are making plans to go further by funding specific projects in Connecticut communities with more direct support from the residents those projects will serve.
“Honeycomb was built on the idea that communities should have a stake in what gets built around them,” said Jackie Logan, Director of Climate Finance at Honeycomb Credit. “Our partnership with the Connecticut Green Bank has proven that model works at scale. This agreement is about taking it further – connecting more Connecticut residents to more climate projects, and turning individual investors into a real force for the green economy.”
Projects on the Horizon
The new agreement opens the door to a range of project-specific investment opportunities currently under exploration, including distributed solar projects, electrification of school buses, and other clean energy and environmental infrastructure initiatives. Connecticut residents, and individuals all over the U.S. will be able to invest starting at $100, completing the process in minutes on desktop or mobile.
The Connecticut Green Bank is emerging as a nexus for community climate investment – a platform where residents, foundations, and institutions can come together around a shared stake in Connecticut’s green future. Together, the two organizations are building what they believe can become a model coalition of climate project investors: one community, one offering, one project at a time.
Green Liberty Notes Round 16 Now Available
While working toward these specific project raises, the Green Bank will continue to offer quarterly Green Liberty Notes through the Honeycomb Credit platform. A Note celebrating Earth Month is now open, and as with the prior raises, investors can participate with as little as $100. To learn more, please visit www.greenlibertynotes.com.

Green Liberty Notes, which are offered quarterly, can be purchased with a minimum investment of just $100. The Notes are offered through Green Bank’s partnership with Honeycomb Credit using their online crowdfunding website. To date, more than 60% of original investments have been $1,000 or less, and more than half of the investors have been Connecticut residents.

Investments in the Green Liberty offering support Eversource’s Small Business Energy Advantage (SBEA) program, which enables small businesses in Connecticut to reduce their energy costs through efficiency upgrades and zero-interest loans.
