In honor of Earth Day, Mayor Bill de Blasio released an update of the Bloomberg-era "PlaNYC" sustainability project Tuesday, including a first-time detailing of the city’s post-Sandy resiliency efforts.

The 107-page report details progress made in 389 initiatives to better prepare the city for climate change and a booming population that is expected to reach 9 million resident by 2030. Though the city's charter requires the mayor to submit an annual report analyzing the environmental health of the city, PlaNYC, originally laid out by Mayor Michael Bloomberg in 2007, was larger in scope and more ambitious, and targeted areas like housing, transportation, water and many others. One of the most controversial aspects of the plan was the introduction (and subsequent failure) of a congestion pricing scheme that would charge vehicles a fee for driving into Manhattan's central business district.

Mr. de Blasio often criticized Mr. Bloomberg during his campaign for mayor, but applauded his efforts to green the city and expand its environmental programs. This progress report is a clear sign of Mr. de Blasio's embrace of PlaNYC and his predecessor's environmental legacy.

But in the wake of Superstorm Sandy, Mr. de Blasio is adding resiliency efforts to the already long list of initiatives. Those efforts range from the specific—1.2 million cubic yards of sand added for beach replenishment on the Rockaway peninsula, Coney Island, and Staten Island, with another 2.9 million cubic yards on track to be placed this year—to the vague—"expanding efforts to ensure that post-Sandy rebuilding and hazard mitigation efforts lead to economic opportunities for all New Yorkers."

Here are some other updates:

Expanding the city’s "Carbon Challenge" to include multifamily buildings to accelerate energy efficiency;

Supporting building owners converting to cleaner sources of energy;

Reducing citywide greenhouse gas emissions by 19% since 2005;

Moving forward a solar energy system that will increase the city’s renewable energy capacity by 50% on the former Fresh Kills landfill site on Staten Island;

500 brownfield sites cleaned up, 70% of which are in underserved communities;

Launching the Food Waste Challenge to divert organic waste from landills, reducing waste by 2,500 tons in the last six months.

"From the cleanest New York City air in 50 years and a real reduction in greenhouse gases, to major progress on coastal protection, building code upgrades, and other key resiliency measures, we are setting a global example for an urban future," Mr. de Blasio said in a statement. "That's why we continue this critical work to ensure a city that is equitable, sustainable and resilient for all."

Mr. de Blasio also made an appearances at an Earth Day event in Union Square, where he announced an effort, with the City Council, to update the city's pollution control code. The changes will impose new regulations on commercial char broilers, fireplaces, food trucks and refrigeration vehicles, in an effort to reduce dangerous particulates. The mayor billed it as the most significant reform since 1975.

"It is the best tool we have to ensure that every possible form of pollution of the air is addressed, and addressed stringently," he said. "We're going to make sure we do that."
