On Wednesday, Mayor Bill de Blasio of New York, in his most sweeping bid yet to focus on income inequality across the municipal spectrum, will be introducing a re-imagined take on the city's ambitious environmental program, PlaNYC.

Officials said that the city has pledged to lift 800,000 residents out of poverty or near-poverty in the next ten years. It will be the largest urban poverty reduction effort ever in the country, and will significantly reduce the 'racial/ethnic disparities' in premature mortality.

According to the plan, the administration will move for the creation of some 500,000 housing units by 2040. It will help the average New Yorker reach hundreds of thousands of jobs by transit within 45 minutes.

Along with the series of lofty goals there will be a new name, OneNYC. It will rebrand what perhaps was the defining document of Michael R. Bloomberg's tenure as mayor. A 'sustainability and resiliency blueprint' informed the long-term policies, including carbon reduction goals and coastal protections against extreme weather.

Although Mr. de Blasio has praised his predecessor's legacy on environmental issues, yet there were some advocates who quietly complained that the emphasis on equity could dilute the program's founding purpose in other areas.

On Tuesday, during an interview at his City Hall office, Mr. de Blasio casted the new plan as a sensible marriage of past practice and his chief political issues.

Mr. de Blasio said, "Environmental sustainability and economic sustainability have to walk hand in hand. Some of my brothers and sisters in the environmental movement don't get that yet". He added that a beautifully sustainable city that is the playground of the rich doesn't work for them.

As of late Tuesday, there were some top environmental groups in the city, including some represented on the administration's own so-called sustainability advisory board, which were not shown a full version of the new plan by the administration.
