Buenos Aires Invests $X Million to Expand Smart City Infrastructure Since 2013
Awards for waste management and data tools trace back to sustained spending on infrastructure and open systems since 2013.
How we reported this

Buenos Aires secured the Smart City of 2021 award at the Smart City Expo World Congress for its Municipal Solid Waste Management Plan that targets reduction, segregation and circular models.
The recognition aligns with broader spending patterns that have supported technology upgrades across city operations. Local officials have channeled resources into programs that convert existing assets into data-driven systems, creating measurable efficiency gains without reliance on external comparisons.
Certification and data platforms
The city became the first Latin American municipality to earn What Works Cities Gold certification. It also deployed CIUDAD 3D, a data tool for urban development that received the 2022 World Smart City Awards. These steps followed the creation of a Citywide Data Strategy and full compliance with the Open Knowledge Index for 100 percent data openness.
Citywide Data Strategy documents show how open records now feed evidence-based decisions in multiple departments. The approach replaced fragmented records with unified access points that planners use for project scoping and performance tracking.
Lighting retrofit and district projects
Since 2013 the city has replaced 91,000 street lights with smart LEDs that include remote tele-management controls. The change produces annual savings of 44.5 million kWh and has cut 9,866 tons of CO2 emissions to date. Parallel work under Plan Nanocentro converts a technology district through expanded bicycle paths, pedestrian zones and real-time safety information systems.
These upgrades illustrate how capital allocated to hardware and sensors generates recurring operational returns. Annual energy reductions free budget lines that can support further sensor installations or data platform maintenance.
Continued execution of the Citywide Data Strategy and Municipal Solid Waste Management Plan will determine the next phase of measurable outcomes from the existing investment base.
