At the recent Data for Good Exchange, Oliver Wise, Analytics Director for C40 city New Orleans talked about how the city is using open data platforms to drive economic recovery post Katrina and enhance climate resiliency. Part of this effort included developing an app called “Blight Status,” which uses open data to track progress and results in reducing urban blight in the city.

In a video of his remarks, Oliver Wise noted the growing need for cities to leverage data to set priorities, deliver on targets and measure results – all to the benefit of urban citizens:

“What we need is talent in government – and city government in particular – who know how to use that data to identify challenges that departments are having and then deliver some intervention…to help deliver better services to citizens.”


Earlier this year marked ten years since Hurricane Katrina devastated the coastal C40 city of New Orleans. Under the leadership of Mayor Mitch Landrieu, the city has undertaken significant efforts to enhance resilience against climate threats.

The lessons learned in New Orleans can apply to cities around the world, and here at C40 we are committed to transparency and accountability through open data. Indeed, our very own Seth Schultz, C40 Director of Research, Measurement & Planning also participated in the Data for Good Exchange, chairing a panel discussion on using data to solve city problems.
