C40’s new Sustainable Urban Development Network is just getting started, but as the Wall Street Journal points out today, and as we’ve been saying for a while ourselves, cities around the world have been taking the lead on low-emission development projects for years.

In a piece entitled “São Paulo Seeks to Be Sustainable,” the Wall Street Journal profiled the sustainable development work of C40 City São Paulo through its Água Espraiada Operação Urbana program which is a critical part of Sao Paulo’s efforts ramp up energy efficiency, cut water usage and ease traffic congestion and greenhouse gas emissions.

The piece quotes Oswaldo Massambani, senior adviser from the Urban Development Secretariat of Sao Paulo, who recently presented São Paulo’s program to the C40 Climate Leadership Group workshop on sustainable communities in Melbourne:

These projects have a lock-in effect for decades to come, so it is critical to get them right. The public spaces and the integration of residential and commercial structures at Água Espraiada show what is possible when our city and developers work together to improve the urban environment.

The article also quoted the new chairman of the C40 Sustainable Urban Development Network Lord Mayor of Melbourne Robert Doyle who said, “City leaders know that sustainability and economic growth are inexorably linked.”
