A Billion-Dollar Local Climate Program
Portland, Oregon, has built one of the most ambitious local climate funding programs in the United States. Over the past seven years, the city has used its Portland Clean Energy Fund to finance projects that reduce emissions, lower energy costs and help vulnerable residents adapt to climate change.
The fund has supported a community solar project for 150 low-income families, distributed more than 20,000 free air conditioning units, paid for energy efficiency upgrades in 3,100 homes and trained 2,000 people in renewable energy and construction fields.
A Tax On Large Retailers
The Portland Clean Energy Fund was approved by 65% of voters in 2018. In 2019, the city began collecting a 1% retail sales tax from large corporations operating within Portland city limits, including major chains such as Target, Walmart and REI.
Unlike a traditional sales tax paid directly by consumers, this structure requires companies to pay the city a small percentage of each sale. Since launching, the fund has generated about $1 billion and is projected to reach $1.6 billion by mid-2029.
Climate Action With A Justice Focus
The fund was created by leaders from nonprofits run by communities of color, who wanted a new way to pay for climate action while centering the people most affected by climate change.
Portland Clean Energy Fund program manager Sam Baraso said the program was born from the experience of front-line communities that have often been hit first and hardest by the climate crisis while being left out of decision-making. The fund asks what solutions look like when those most affected help design them.
Projects Already Deliver Results
Projects funded so far include free portable air conditioning units for vulnerable households, a solar project in a predominantly Latino neighborhood, tree planting in urban heat island areas and the removal of concrete parking lots to create gardens and community spaces.
Since 2021, the fund has distributed four rounds of community-based nonprofit grants worth about $262 million. Grant sizes range from roughly $8,000 to $10.3 million, with many projects designed to cut greenhouse gas emissions while improving household resilience.
Emissions Cuts And Local Benefits
Portland’s City Budget Office estimates that completed projects from the first three rounds of grants have reduced about 25,500 metric tons of carbon emissions. That is roughly equivalent to removing 6,000 gas-powered vehicles from the road for one year.
The emissions impact is expected to grow as more projects move forward. Supporters say the fund has endured because residents can see themselves and future generations benefiting from cleaner energy, lower bills and stronger community infrastructure.
Success Brings Political Debate
The fund has generated far more money than originally expected, creating debates over how the money should be spent and what qualifies as climate action.
Portland Mayor Keith Wilson has proposed using $75 million to renovate the Moda Center with green technology, while critics argue that the project does not align closely enough with the fund’s mission of helping vulnerable communities first. The Portland Police Association has also proposed diverting 25% of annual fund revenue to hire 400 additional officers, a plan opponents say would undermine the fund’s original purpose.
Other Cities Look To Portland
Portland’s model has attracted attention from other cities seeking dedicated climate funding. Denver, Ann Arbor and Seattle have developed similar programs, although each has adapted the structure to local tax rules and political conditions.
Denver created a 0.25% sales tax for its Climate Protection Fund, while Ann Arbor raised property taxes to support climate action. Experts say Portland’s approach shows how local buy-in can generate meaningful climate investment, but smaller cities may need different funding tools. By mid-2029, Portland expects to complete its first five-year plan and invest $1.6 billion back into the city.
