The city also announced a new plan, whose goal is to remove its $189 billion pension system from fossil fuel reserve owners over the next five years, thus becoming the first major U.S. pension plan to complete such an exit, according to international sources.

According to the lawsuit which was filed earlier this week, the city says that it experiences serious problems, caused by climate change, such as coastal erosion and tidal flooding.

These dangers cause important risks to the city's infrastructure and the health its residents.

These risks will have a huge costs, as billions of dollars are expected to be spent. For this reason, New York's Mayor, Bill de Blasio said that "It's time for Big Oil to take responsibility for the devastation they have wrought," during a press conference.

According to Mr. de Blasio, the oil industry is largely accountable for the recent extreme weather events, such as Hurricane Sandy.

Furthermore, the lawsuit undiscloses specific documents, according to which, the industry was aware off the danger that burning fuel was causing, thus leading to climate change.

Exxon commented that it welcomes any action that has good-faith in addressing the matter of climate change, with Chevron saying that the lawsuit will not make a positive impact on climate change.

Conoco and BP did not make a statement.

At the moment, New York's officials are drafting a proposal in order to ensure that such a plan will be executed in an effective way.
