• planyc, is an effort released by New York City Mayor Michael Bloomberg in 2007 to prepare the city for one million more residents, strengthen the economy, combat climate change, and enhance the quality of life for all New Yorkers. The Plan brought together over 25 City agencies to work toward the vision of a greener, greater New York. Since then, significant progress has been made towards the long-term goals set by the Plan.

PlaNYC specifically targets ten areas of interest: Housing and Neighborhoods; Parks and Public Spaces; Brownfields; Waterways; Water Supply; Transportation; Energy; Air Quality; Solid Waste; and Climate Change.

Over 97% of the 127 initiatives in PlaNYC were launched within one-year of its release and almost two-thirds of its 2009 milestones were achieved or mostly achieved. The plan was updated in 2011 and has been expanded to 132 initiatives and more than 400 specific milestones for December 31, 2013. (Wikipedia), GreeNYC

Climate change mitigation

The NYC Mayor's Office Climate Policy and Programs team, who also manages the OneNYC program, said in 2018 that it is pledging to reduce greenhouse gas emissions by 80% by the year 2050 and align with the 1.5 degree Celsius target put into place under the Paris Agreement. Inroads have already begun, as the city's emissions have decreased 15% since 2005. The aim is to develop low-carbon transportation options and mandate retrofits to city buildings. In 2018 the team has sued five companies (BP, Chevron, ConocoPhillips, Exxon Mobil, and Royal Dutch Shell) for being responsible for climate change,[8] and divesting the City's pension funds from fossil fuels, the first major US city to do so. Mayor Bill de Blasio stated in support of the decision, "As climate change continues to worsen, it's up to the fossil fuel companies whose greed put us in this position to shoulder the costs of making New York City safer and more resilient."

The OneNYC program as of 2018 made progress towards renewable energy reliance; for instance, solar installations have increased six-fold since 2014, $500 million was invested to improve building energy efficiency, and an additional $1 billion allocated to preserving NYC's drinking water. ^W

Response to coastal flooding

Flooding was the second highest cause of weather related fatalities in the United States in 2018. The projected 11-21 inches of sea level rise in New York City by 2050 and 4.17–9 feet by 2100 will compound the impacts of coastal flooding. The damage caused by Hurricane Sandy in 2012 served as an impetus for policymakers and residents to more seriously consider coastal resiliency efforts. Since then, regulations have been strengthened[15] to better protect the 400,000 New Yorkers in the one percent annual chance floodplain. Additionally, in May 2017, New York Governor Andrew Cuomo announced the construction of a 5.3 mile seawall along the Staten Island coastline capable of withstanding coastal flooding of 15.6 feet, two feet higher than that caused by Hurricane Sandy. When completed, the seawall will reduce damages by approximately $30 million. ^W

Adaptation to climate change

New York in 2009 launched a task force to advise on preparing city infrastructure for flooding, water shortages, and higher temperatures. The New York City water supply system has been built to provide for its water needs. The NYC Mayor's Office Climate Policy and Programs team is investing $20 billion to adapt the city's neighborhoods to climate change threats like flooding, heat, and sea level rise.

The Lower Manhattan Coastal Resiliency initiative aims to address threats to the Financial District and surrounding neighborhoods.

In 2019, the city allocated $615 million for a 5.1 mile East Shore Seawall, a combined seawall and walkway on Staten Island, officially called the Staten Island Multi-Use Elevated Promenade. ^W

Climate change in New York City

From Wikipedia:Climate change in New York City

Climate change in New York City could affect buildings and infrastructure, wetlands, water supply, public health, and energy demand, due to the high population and extensive infrastructure in the region. As a seaport, New York is especially at risk from rising sea levels due to its many bridges and tunnels. Major aviation facilities in the New York metropolitan area, along with the New York Passenger Ship Terminal, are also located in areas vulnerable to flooding. Flooding would be costly to remediate. Tide gauge records indicate a rise in sea level of about 50 cm (20 inches) since 1860.

Rising temperatures could increase the risk of heat-related deaths during heat waves and increased concentrations of ground-level ozone (potentially causing asthma and other health concerns). The New York Times identified climate change as a contributing factor in the city's rising rat infestation, stating that "[m]ilder winters — the result of climate change — make it easier for rats to survive and reproduce".

In June 2019, New York City declared a climate emergency.

Bike New York - Citi Bike, bicycle sharing system

Wikipedia:

Cycling in New York City is associated with mixed cycling conditions that include dense urban proximities, relatively flat terrain, congested roadways with "stop-and-go" traffic, and streets with heavy pedestrian activity. The city's large cycling population includes utility cyclists, such as delivery and messenger services; cycling clubs for recreational cyclists; and, increasingly, commuters. While New York City developed the country's first bike path in 1894, and recent trends place the city "at the forefront of a national trend to make bicycling viable and safe," competing ideas of urban transportation have led to conflict, as well as ongoing efforts to balance the needs of cyclists, pedestrians, and cars.

Bike New York is an organization based in New York City that encourages cycling and bicycle safety. They are best known for producing the Five Boro Bike Tour, the largest recreational cycling event in the United States. The Tour, which occurs on the first Sunday of May every year, takes 30,000 riders in a 42-mile ride around New York City. Bike New York also produces smaller rides, offers free classes to the public, and develops customized bicycle safety and education programs in and around New York City.

Citi Bike is a privately owned public bicycle sharing system that serves parts of New York City. It is the largest bike sharing program in the United States.[3][5] The system opened to the public in May 2013 with 330 stations and officially with 6,000 bikes, but six weeks later, the actual number in use appeared to be less than 4,300.

wikipedia:Environmental issues in New York City are affected by the city's size, density, abundant public transportation infrastructure, and location at the mouth of the Hudson River. New York's population density has environmental pros and cons. It facilitates the highest mass transit use in the United States, but also concentrates pollution. Gasoline consumption in the city is at the rate the national average was in the 1920s, and greenhouse gas emissions are a fraction of the national average, at 7.1 metric tons per person per year, below San Francisco, at 11.2 metric tons, and the national average, at 24.5 metric tons. New York City accounts for only 1% of United States greenhouse gas emissions while housing 2.7% of its population. In September 2012, New York was named the #1 "America's Dirtiest City," by a Travel+Leisure readership survey that rated the environmental quality of 35 prominent cities in the United States.
