The new figures, published in the journal _Nature Climate Change_, show Americans disposed a total of 262 million tons of waste in 2012_._ The study’s lead author, Yale University researcher Jon T. Powell, notes that previous research has used indirect information, like [trade data](http://www.epa.gov/wastes/nonhaz/municipal/pubs/2013%5Fadvncng%5Fsmm%5Frpt.pdf), to measure trash levels in landfills, potentially leading to lower estimates. His study aims to provide a more accurate estimate by using data taken from individual landfills. The higher numbers are especially significant because trash in landfills releases methane gas, a greenhouse gas that contributes to climate change. The Environmental Protection Agency (EPA) estimates that landfills are the third-leading cause of methane emissions in the U.S. Nearly a fifth of of methane emissions come from landfills. Landfills utilize methane gas collection technology, but researchers say that methods should be improved at open landfill sites. “We’ve got a lot of waste going into landfills, more than what’s been reported before,” said Powell. “What that means for the long term is that we’re going to have greater emissions.” **Read More**: [EPA Proposes New Rules to Cut Climate Change-Causing Methane Emissions](http://time.com/4001548/epa-methane-rules/) Methane is the second most prevalent gas emitted by human activity following carbon dioxide. And, while Americans emit significantly less methane than carbon dioxide, methane emissions are 25 times more damaging to the environment, pound for pound, than carbon dioxide over a 100-year period. The EPA [recently announced](http://time.com/4001548/epa-methane-rules/) new rules to reduce methane emissions, but the policies target the oil and gas industry without taking on key sources of methane emissions like landfills and agriculture. (In a different announcement, the agency proposed requiring more landfills to capture methane gas emissions). The need to address pollution from landfills may be growing as urbanization pushes people into cities and increases waste. Today, 54% of people around the globe live in cities, and those cities could see their populations rise by 2.5 billion by 2050, according to a United Nations [estimate](http://www.un.org/en/development/desa/news/population/world-urbanization-prospects-2014.html). “As that urbanization occurs, you have more materiality, more consumption, and that begets residuals of waste materials,” said Powell. **Correction**: The original version of this story misstated the name of the study’s lead author. He is Jon T. Powell. ## Transcript >> You're looking at a particularly beautiful section of Staten Island's New York. But these hills were not shaped by glaciers or wind erosion. Underneath this grass is 51 years worth of garbage from New York City. The Fresh Kills landfill is such a sore subject for New Yorkers that anthropologist Robin Nagle works with the city's sanitation department to try and change its image. Her first tip, don't call it a landfill. >> It's not an active landfill, it was an active landfill and the park will be built on top of that, like many other parks in to New York City's system. In fact, 33 percent of Manhattan below 14th Street is filled land and much of that fill was created through household trash across centuries. When you dig that up today, you're not looking at, we don't define that as trash from the colonial Dutch or colonial English. We define that as archaeological artifact, and treasure, and historical remnant and clue to our past. It's possible that years from now and I'm talking decades or centuries from now parts of this land will be excavated with a similar eye. >> Park planners say it'll take 30 years to fully open it to the public at a $ 1 million an acre. Covering 2, 200 acres Fresh Kills Park will be nearly three times the size of Central Park. But what makes this park so unusual isn't only its size, it's what's happening beneath your feet. >> This place which looks so beautiful is an engineered landscape. Underneath this landscape there are three different systems that are managing what's going on here. There's a-- there's a landfill gas management system which is a series of pipes, actually you can see some of the pipes here sticking out of the ground. >> The landfill gas is purified and sold to National Grid which in turn heats 22, 000 Staten Island homes. There's a system for rainwater and another for dealing with leachate, the liquid that seeps to the bottom. >> We could have a lot going on here that will inform what people are doing for landfills and brownfields reclamation all over the country, potentially all over the world. >> Though the park isn't open yet, tourists are offered, rain or shine to get people used to the idea of hanging out in Fresh Kills. >> If we love ourselves we have to love this place as a remarkable record of ourselves, of our culture, of this City, of this moment in time. >> But there are reasons aside from its name that Fresh Kills is hard to love. 1. 2 million tons of material from the World Trade Center were taken and investigated here. The City faces an ongoing lawsuit from victims' families who object to having what may be the remains of their loved ones buried in a dump. And then there's Staten Islanders who've lived with this landfill for half a century. Although the site is carefully monitored now there's little data on the toxins that may have been released in the past. >> I think you really cannot-- you can't overestimate how deep a scar this left on the psyche of the people of Staten Island and it takes time to heal from that and I think that there's a lot of skepticism understandably. We have to-- we have to build it, but I know that'll come.
