Climate Budgeting to Help Reach Zero Net Emissions

New York City has a goal to reach net-zero emissions citywide by 2050.

To reach that goal, city leaders must put data at the heart of day-to-day operations. One way the City is doing this is through a new municipal climate budget. As part of the climate budget, the City bolstered requirements for capital project budget requests to include projected emissions data, which are now being met by 100 percent of city agencies, contributing to a 27 percent reduction in greenhouse gas emissions from government operations.

“Climate budgeting is a significant shift in how we think about the value of tax dollars and their potential to power change. It’s the only way to use every budgeting decision to bring our climate ambitions to life. There’s no time to waste.”

Eric Adams, Mayor

Climate budgeting is a governance system that mainstreams climate targets and considerations into decision-making through the budget process and aligns the City’s resources with its climate goals. It is a paradigm shift from the traditional budget process to a holistic approach that considers the impact of every dollar the City spends on meeting its climate goals.

NYC’s climate budgeting is a core component of the City’s strategic climate plan announced in 2023 and is being led by New York City’s Office of Management and Budget, in partnership with the Mayor’s Office of Climate and Environmental Justice (MOCEJ).

An early example of climate budgeting can be seen in the “Leading the Charge” initiative, a $4 billion plan now in motion, to ensure newly constructed schools will be all-electric and 100 existing schools will begin to phase out fossil fuel heating systems. The initiative will prioritize schools in low-income as well as predominantly Black and Brown communities which are particularly vulnerable to environmental injustices such as elevated rates of childhood asthma. The electrification plan illustrates how NYC is using emissions data to combat climate change and disaggregated demographic data to promote equitable health outcomes.


How else has NYC become a more data-driven government?

As one of the first big cities in the U.S. to adopt climate budgeting, New York City is showing how new decision-making processes can deliver urgently needed change. 

In 2024, it will implement a formal climate budgeting intake form for agency budget requests and publish its first Climate Budget alongside the Executive Budget. The Climate Budget will include a citywide greenhouse gas emissions forecast showing progress toward the 2050 net-zero goal, as well as data that shows how capital project plans could affect climate goals such as air quality and heat and flooding resilience. The 100% compliance rate across departments is a positive sign for standardizing climate budget processes and understanding the City’s emissions.

Does climate budgeting make funding decisions more complex? Yes. But the initiative is worth it. It allows New York City to understand the climate impact of dollars spent and then rally around forward-looking projects aligned to must-reach goals.

“By using a data-driven decision approach, our administration is delivering results for New Yorkers in the most efficient and equitable way possible. Data is more than just a spreadsheet — it is a tool to help government better improve services that impact the daily lives of residents. I’m proud that New York City is recognized as an international leader in operations and look forward to continuing to use data to improve the lives of New Yorkers.”

Created a cross-departmental team that identifies the most effective methods for achieving the city’s top goals and leads the city’s data-driven transformation.


Found patterns in 911 repeat call data that signaled the need for a new referral program to deliver specialized healthcare and social services for residents. Within the first three months of launching the program, there was a 70% reduction in calls from its top 911 utilizers.


Partnered city agencies and civic tech nonprofits to develop a text reminder system that reduced missed fines and warrants that have helped the City’s Court see an annual 187,000 increase in revenue.

Using Data to Power Innovation

G.T. Bynum has leadership in his veins. One of the youngest people ever elected mayor of Tulsa, Oklahoma, he’s the fourth person in his extended family to serve in the role since the turn of the last century. But he is the city’s first mayor to place data-driven decision making at the top of a change agenda. Since becoming mayor in December 2016, his administration has marked a turning point in how Tulsa uses data to power innovation and improve the quality of life in Tulsa.

Mayor Bynum didn’t waste any time after being elected. The idea of improving city services and using data to make key decisions was at the core of his mayoral campaign. One of his first moves as Mayor was the creation of the Office of Performance Strategy and Innovation (OPSI). The office works to align the city’s top goals with effective strategies. It quickly became key to the city’s data-driven transformation, says James Wagner, who led OPSI at its inception and is now the city’s director of finance and CFO.

Ben Harris, OPSI’s Data Analytics Manager, convened a team of employees from 16 departments to lead the city’s data governance and strategic planning efforts. The Data Governance Committee, which sets the standard and strategy for data quality, integrity, and use for the city government, has helped integrate the use of data citywide through the creation of a Central Data Repository where any employee or resident can request data.

“Through this cross-departmental team, we encourage transparency, access to data, and a feedback loop; ultimately it creates a trust relationship between departments,” Harris said.

“In addition to teamwork, technology played a huge role in orchestrating communication, automating data movement, securing data, and making it accessible.”

OPSI and the Committee also facilitate regular sessions with department leaders to focus on the value of performance metrics. These meetings aren’t just about tracking progress reviewing data — they’ve created a new space within the city to cultivate innovation.

“Mayor Bynum and other city leaders have consistently looked to OPSI to drive data-driven innovation work in Tulsa. This matters because we’re making real changes that improve city services and save taxpayers money.”

Chief Financial Officer James Wagner

A Caring Fire Department

For years, the number of calls to the Tulsa Fire Department was increasing, putting stress on their resources and capacity. By analyzing the data, the fire department discovered the source of the increased calls was not an increase in fires, but instead an increasing aging population who needed lift assists. Lift assists are calls to the 911 system for a non-emergency fall — the help the resident is requesting is to literally be picked up off of the ground. The city discovered a repeat lift assist pattern, with some residents requesting a lift assist as many as nine times a day.

Under the direction of Chief Michael Baker, the Fire Department developed and launched the Tulsa Community Assistance Referral and Educational Services (CARES) program, which was designed to connect high-utilizers of the emergency system to healthcare and social service providers. Visits to the highest utilizers became proactive, with the CARES team working on simple fixes such as installing low-cost solutions like handrails and opening up a dialogue with the resident’s primary care doctor. Within the first three months of the pilot, the fire department saw a 70 percent reduction in calls from its top 911 utilizers.

With preliminary results in hand, Baker presented his findings through the TulStat forum.

“TulStat,” based on the successful “LouieStat” program out of Louisville, Kentucky, has created a forum for change in Tulsa. City leaders gather to discuss priority problems, define success, innovate solutions, and develop methods for measuring progress. They identify specific, quantifiable goals, such as average time for reviewing building permit applications (previously 5 weeks, now 92 percent completed in 5 days) or responding to a 911 call, and troubleshoot obstacles to achieving them.

While CARES was developed before Bynum’s administration founded TulStat, having a space to build off of the pilot’s success was critical in connecting more residents to much-needed services. The program has served 204 clients; in 2020, four Tulsans have “graduated” the program and have the needed support services in place for them to live safely in their homes.

In the future, CARES hopes to work with OPSI to expand their data capacity to learn how to predict who is at risk for becoming a repeat caller to the 911 system and intervening early to distribute tools and services. Aligning community resources to provide innovative, proactive care will not only save the city’s Medicare and Medicaid partners money, it could save a resident’s life.

Breaking the Cycle

Working with What Works Cities and the Behavioural Insights Team, OPSI also helped the Tulsa Municipal Court solve a problem that had burdened the court and vulnerable residents for years.

Previously, when the court issued a resident a fine in a criminal case, but that resident wasn’t able to pay that fine on time, the court would offer an extension in the form of a “Time to Pay Order.” Some found themselves with a fine due more than 12 months in the future — enough time for them to save money for the payment, but also plenty of time to forget when it was due. As of early 2018, more than 70 percent of those orders resulted in a failure-to-pay warrant. For many, a warrant can exacerbate the cycle of poverty: a driver’s license might be suspended and additional fines can accrue, pulling someone further into the criminal justice system.

To combat the problem, OPSI partnered with the Court and Code for Tulsa to figure out how to reduce the number of warrants issued. Within a month, a text message pilot project was underway, designed around a simple hypothesis: Many people missed their Time to Pay Order deadline because they forgot the due date or lost paperwork. Together, OPSI, the Court, and Code for Tulsa developed a system to text simple, personalized reminders to a randomly selected pool of Time to Pay Order recipients. The test group received a text message reminder once a month leading up to their deadline.

The results were remarkable. During the six-month pilot, 63 percent of those who received a reminder paid all of their outstanding fees, compared to 48 percent of residents who did not receive reminders. Armed with data showing this 15 percent point increase, the Court system adopted the new reminder system. It now estimates an additional 320 people are paying their fees on time each year, avoiding warrants and additional problems because of the system. The Court benefited as well, seeing an annual $187,000 increase in revenue and a morale boost among employees who helped implement the solution.

“I’ve never been so excited about a job,” said Jamie King, a cost administrator at the court.

At the City’s Core

OPSI’s successful partnerships with city departments go beyond the fire department and courts. Three years in, OPSI has implemented practices and programs that have positioned Tulsa as a leader in data and innovation. In 2017, the office launched Urban Data Pioneers, an award-winning program consisting of teams of residents and city employees who analyze data to help the city solve key challenges and present policy recommendations.

With OPSI’s clear-cut ability to drive innovation, Mayor Bynum decided to integrate the office into the city’s key funding decisions. When Wagner became Director of Finance and CFO in early 2019, he brought OPSI with him to the Finance Department. This has changed the way Tulsa funds innovation. In essence, a data-driven approach has been institutionalized and scaled. Today, the city bases funding on data that proves programs work. OPSI vets data.

“We had the opportunity to take the approach and plug it into the finance department,” Mayor Bynum said. “It helps make it have much more of a citywide cultural impact.”

New Orleans: From “BlightState” to Preventing Fire Fatalities.

Created a data-driven performance management program and a website that aggregates data about important housing information to address blighted homes post-Hurricane Katrina, resulting in more than 15,000 fewer blighted addresses by 2018.


Worked with What Works Cities partner the Behavioral Insights Team to devise a “nudge” letter to owners about housing violations, resulting in a 10 percent drop in cases moving to the hearing stage, saving staff time and city funds.


Developed a predictive model that identified which parts of the city were most at risk for fires and fire fatalities using that information to target its campaign to distribute smoke alarms to vulnerable households.


Targeted anti-gang violence via prevention efforts and rehabilitation, which led to an 18 percent decrease in the number of murders as of 2016.

New Orleans’ Creation of New Orleans

One Thursday morning, some ten city officials seated in a u-formation of tables faced an audience of some two dozen local residents in a room at New Orleans City Hall. The city staff and residents all knew each other by first name, and they bantered a bit back and forth, which was no surprise as many have been regulars at this monthly meeting for years, regularly returning to follow progress and to fight for the removal of blighted properties that have proven more difficult to address in their neighborhoods.

BlightStat, a data-driven performance management program, has been in place since 2010. When Mayor Mitch Landrieu took office in May 2010, New Orleans faced what has been described as one of the worst blight problems in the U.S., “with no strategy to address it,” the City notes. A large part of the problem was the aftermath of Hurricane Katrina, which devastated the city in 2005. Five years later, faced with thousands of homes that could not be saved, Mayor Landrieu instituted BlightStat to ensure that the City’s efforts to get rid of the blighted homes would proceed efficiently and effectively.

BlightStat set priorities for the inspectors and researchers who identify rundown properties and determine whether to levy fines, order a demolition, force a sale, or take some other action. Under the BlightStat framework, the City considers issues such as the condition of the roof and foundation, the owner’s history of tax payment, and the market for real estate in that neighborhood, trying to predict the cases that will have the best outcomes so that the Department of Code Enforcement can decide how to best to deploy its resources.

New Orleans has 15,000 fewer blighted properties thanks to BlightStat, a data-driven performance management program that’s helped the City strategically address the issue.

The City also created BlightStatus, a website that aggregates data about inspections, code compliance, hearings, judgments, and foreclosures, providing users with a simple search box that unlocks all the information available for any address in the city. It opened up a new, easy-to-use link between the city and community, keeping everyone on the same page and giving residents the chance to make their voices heard. The tool also helped city employees keep up-to-date with changes to properties and stay accountable for promised changes.

By 2018, New Orleans had more than 15,000 fewer blighted addresses, accomplished through a mix of demolition, sale, and owner repairs, aiding vastly in New Orleans’ recovery.

New Orleans also worked with What Works Cities partner the Behavioral Insights Team to devise a “nudge” letter to owners about housing violations, resulting in a 10 percent drop in cases moving to the hearing stage, saving staff time and city funds.

New Orleans’ use of data undergirds many of its major programs. “We use data to plan. We use data to create an iterative process that informs implementation. Data is baked into our culture; it’s a part of our subconscious,” says Oliver Wise, former Director of the Office of Performance and Accountability (OPA), who was succeeded by Melissa Schigoda.

OPA runs the City’s data analytics initiatives. Along with BlightStat, they include ResultsNOLA, which evaluates the performance of city departments, and NOLAlytics, which helps those departments conduct their own data analytics projects to support their missions.

In one project, OPA developed a predictive model that identified which parts of the city were most at risk for fires and fire fatalities. The City used that information to target its campaign to distribute smoke alarms to vulnerable households. Using analytics, it identified twice as many households in need of smoke alarms than it had when the City chose households at random. Less than a year later, there was a fire in an apartment building in one of the neighborhoods that the City had identified, and eleven people escaped — all because of a very cheap, but strategically installed, smoke alarm.

To address its high murder rate, the City instituted its NOLA for Life initiative in 2012, targeting anti-gang violence via prevention efforts and rehabilitation, which led to an 18 percent decrease in the number of murders, as of 2016.

Mayor Landrieu, who left office in May 2018 after serving two terms, says he has always been data-driven, realizing that if you can’t measure something, you can’t assess outcomes. “Data shouldn’t make you look good — it’s intended to tell you the truth,” he says. “The results can speak for themselves.”

Mayor Mitch Landrieu signs the City’s open data policy, in 2016.

Landrieu says he told staff from the start that he “wanted to count everything” and to fold that sensibility into the budgeting process to run a “leaner, more efficient government.”

Landrieu says a “culture of counting” will have a real impact on the ground and make a difference in people’s lives. He created a Neighborhood Engagement Office to ensure managers are more connected to residents and see to it that “everybody’s data can matter.

As he looks back at his administration, Landrieu says he’s most proud of the team he assembled for their focus on getting things done in a data-driven fashion, and the processes they put into place to encourage innovation. “These processes were designed to last,” he says, “not to be a flash in the pan.”

“If you measure and it’s real, you gain the confidence of the public.”

Minneapolis’ Data-Driven Green Cost share Program Delivers Environmental Justice.

Prevented more than 11,000 metric tons of carbon dioxide from entering the atmosphere through a data-driven incentive program to help Minneapolis property owners invest in energy efficiency upgrades and other green projects.


Developed a Green Career Program to increase solar and energy-efficient jobs, economic opportunities, and awareness – particularly in underserved neighborhoods where data showed less participation in green initiatives.


Created the 4d Affordable Housing program for building owners to keep units affordable and maintain energy efficient upgrades for residents.

Minneapolis’s Efforts to Reduce Greenhouse Gasses

The City of Minneapolis has a long history of enacting progressive policies to tackle climate change. Back in 1993, it joined forces with neighboring St. Paul to reduce the emission of greenhouse gasses (GHG) into the atmosphere with its Urban CO2 Project Plan. In 2012, Minneapolis set the ambitious goals of cutting GHG emissions 30 percent by 2025, and 80 percent by 2050.

That same year, Minneapolis took another innovative step with the creation of its Green Cost Share program. It was launched by the City’s Department of Health as an incentive-based — rather than punitive — way to reduce pollution and address climate change. The basic idea is this: The City offers matching funds to residential, commercial, and industrial property owners as an incentive to invest in energy efficiency and pollution reduction projects. The resulting improvements help the City move closer to achieving its climate change goals while also addressing public health inequities.

Data-driven performance management and open data are at the core of the Green Cost Share program — and are playing a growing role in the City overall. In recent years, Minneapolis has strengthened other foundational practices as well, including general management and data governance, all of which help in the City’s efforts to monitor and utilize relevant data. Leaders of the Green Cost Share program collect data on dollars invested, estimated lifetime energy bill savings, and pollutants reduced. And they make everything public through a dashboard presenting all the metrics.

“From how we track progress toward program goals to how we target underinvested parts of the city overdue for environmental justice, data is in many ways the engine of Green Cost Share,” says Patrick Hanlon, who runs the program as director of environmental programs for the City of Minneapolis.

The program kicked off by building partnerships with dry cleaning companies to end their use of perchloroethylene, a cleaning solvent and known toxic air pollutant that may cause asthma, birth defects, and cancer. By 2018, Minneapolis became the first city in the country to be completely “perc”-free.

That was just one program goal. By offering property owners 20 percent of project costs (up to $20,000), the Green Cost Share program has also incentivized the installation of solar arrays, insulation, high-efficiency water heaters and furnaces, and other pollution-reduction improvements across the City. The program’s specific impacts since 2013 are detailed in the dashboard: 580 projects have received match funding, saving 31.8 million kilowatt hours of energy. That’s prevented more than 11,000 metric tons of carbon dioxide from entering the atmosphere — the equivalent of taking over 2,400 cars off the road. Combined, program recipients will be saving over $50,000,000 over the lifetime of their projects.

“Tracking and analyzing data has helped us both define and prove success, as well as course-correct as the program has evolved over the years.”

Director of Environmental Programs Patrick Hanlon

Data-Driven Course-Correcting

The Green Cost Share program’s use of data goes beyond demonstrating impact, however. To ensure the program helps improve public health measures and delivers environmental justice, staff have ramped-up efforts to engage property owners in areas of Minneapolis defined as high-need.

In 2017, program staff noticed they weren’t receiving many applications from areas designated as Green Zones. Mostly located in north and south Minneapolis, the zones were defined by community groups based on demographic, economic and public health data provided by the City. They have higher concentrations of low-income residents and communities of color, and histories of practices like redlining and lease covenants. Not coincidentally, these areas also often have high levels of pollution related to traffic and stationary pollution sources, brownfield sites, and substandard housing. The City’s Green Zone task force expressed a desire for more investment in renewables, energy efficiency, and green jobs.

With the goal of inspiring more projects in the zones and support from the mayor and City Council, the Environmental Programs team adjusted the program’s match funding formula. It began offering a 30 percent match rate of up to $30,000 to applicants in the Green Zones or Great Streets program, another revitalization program that targets areas where people of color and low-income residents are concentrated. Before 2017, only about 20 percent of program participants were environmental justice properties. Today, the figure is 58 percent.

The City of Minneapolis has developed various strategies to support economic recovery from the pandemic and address racial inequities. As part of that comprehensive approach, the Green Cost Share program matches 40 percent (up to $40,000) of the cost to rebuild properties damaged during protests last year following George Floyd’s killing at the hands of a Minneapolis police officer, which sparked a national movement for racial justice. The program continues to look for ways to provide additional incentives, prioritize projects, and build relationships in environmental justice communities. One way it is doing this: A Green Career program launched last year in partnership with the Department of Community Planning & Economic Development (CPED) that focuses on training residents in BIPOC communities for jobs with solar and energy-efficiency contractors. The City is tracking data to evaluate program outcomes.

For all its activities and projects, the Environmental Programs team collects and analyzes data to identify areas for improvement. One need that’s emerged from analysis: a better group purchase program allowing solar developers to aggregate smaller projects like single-family homes to be submitted in bulk to both take advantage of the incentive and reduce overall project costs.

The team also received community feedback about the lack of energy-efficiency projects being done in larger apartment buildings with low-income tenants. A data analysis bore this out, so the Environmental Programs team partnered with the CPED department on its successful 4d Naturally Occurring Affordable Housing program. The 4d program, which provides incentives for building owners to keep units affordable, has successfully helped building owners make energy efficiency upgrades after they signed up for the incentives. The results were significant — Green Cost Share projects in buildings with over 1,000 tenants rose sharply, from three to 49.

“Those are the kind of opportunities that can be revealed by regular, robust project data analysis.”

Contract Manager Isaac Evans

The program is also working to obtain better demographic data about project applicants to make further progress on environmental justice goals. Applications can request (but cannot require) demographic data from applicants; the team is working to improve data sharing between city departments to supplement information and improve demographic data tracking.

“The Green Cost Share program can’t succeed in a silo and it can’t succeed without strong data practices,” Hanlon says. “To align with the City’s overarching climate and equity goals, we know we have to work hand-in-hand with colleagues across city government and residents in need. Sustained collaboration and proactive data-driven performance management are both key to success — for all City programs, really.”

“We look at this program as a way we can intentionally invest back into communities that have been discriminated against historically.”
