Roeland Park residents now have a way to check their household’s and city’s carbon footprint in real time.
It will cost the city $6,000 for the first year and $2,000 for each subsequent year, or a maximum of $4,000 for each subsequent year if the city wants additional services. The company prices its software and action plan based on a city’s building count.
At Monday night’s council meeting, Dynamhex founder and CEO Sunny Sanwar updated the council on the system, which went live on the city’s website Feb. 1.
The software enables users to see real-time citywide carbon emission numbers. It also allows residents and businesses to type in their address to see their building or home’s specific emissions and learn ways to reduce them. That can include steps like adding insulation, installing more efficient heating and cooling systems and solar power.
“Empowering every citizen with that data helps them understand their role in this community health problem,” Sanwar said.
Roeland Park’s emissions
According to council documents, Roeland Park produced 55,117 metric tons of greenhouse gases in 2019, or 8.2 metric tons per resident.
Just over half that came from residential buildings, with the rest from transportation, commercial buildings and industrial facilities.
The per capita figure compares to 16.1 metric tons in Johnson County and 18.2 metric tons in Kansas City, Mo. Roeland Park’s per capita figure is lower because the city has less heavy industry and manufacturing.
The city’s 28% emissions-reduction goal would lower emissions to less than 40,000 metric tons a year overall.
According to council documents, methods to reduce emissions in city-owned buildings may include:
- adding new solar energy systems: estimated 15.8% reduction
- Evergy’s electric grid using cleaner raw material: estimated 12.9% reduction
- implementing building-level efficiency measures: estimated 8% reduction
Getting national attention
Dynamhex bases its carbon emissions evaluation on National Renewable Energy Laboratory models using county building permit information to determine a building’s age and features. This is a common method and the models are accurate 95% of the time, Sanwar said last year.
The software now in use in Roeland Park defines short- and long-term goals for reducing carbon emissions.
In December, Forbes magazine ran a story about Dynamhex’s Roeland Park effort, and Sanwar said Monday that an upcoming New York Times story will include Roeland Park in spotlighting cities’ actions on climate change.
Mayor Mike Kelly praised Dynamhex’s system.
“We appreciate that it’s no small feat to empower people with data,” Kelly said. “You can throw strategies at them all you want, but having data to back it up goes a long way.”
Dynamhex developed the software after pilot operations in Roeland Park, Kansas City, Mo., Washington, D.C. and other East Coast cities.
In September, the Prairie Village City Council also approved a contract with the company to track its citywide greenhouse gas emissions and develop an action plan to reduce them.
