How Buying Stuff Drives Climate Change 

How Buying Stuff Drives Climate Change State of the Planet Columbia Climate School Renée Cho December 16, 2020 Did you know that Americans produce 25 percent more waste than usual between Thanksgiving and New Year’s Day, sending an additional one million tons a week to landfills? This holiday season, with online shopping the preferred gift giving method for many, we will likely generate even more waste mailing packages all over the country. In addition, over two billion Christmas cards are mailed every year, with enough paper to fill a football field 10 stories high. More than 38,000 miles of ribbon are thrown away and usually end up in landfills. Over the holidays, Americans discard half their total yearly paper waste, mostly holiday wrapping and decorations—about nine billion tons. And each person wastes almost 100 pounds of food. 

The problem with stuff......As more people around the world enter the middle class and become affluent, the problem is worsening. What’s all this got to do with climate change? In fact, our consumer habits are actually driving climate change. A 2015 study found that the production and use of household goods and services was responsible for 60 percent of global greenhouse gas emissions. Not surprisingly, wealthy countries have the most per capita impact. A new U.N. report found that the richest one percent of the global population emit more than twice the amount than the poorest 50 percent; moreover, the wealthier people become, the more energy they use. A typical American’s yearly carbon emissions are five times that of the world’s average person. In 2009, U.S. consumers with more than $100,000 in yearly household income made up 22.3 percent of the population, yet produced almost one-third of all U.S. households’ total carbon emissions. After basic needs are met, consumers begin buying items for social status; as people try to acquire more and more status, more and more expensive status products are needed. Producing all these things generates climate-changing greenhouse gas emissions. And in fact, across its life cycle, the average product results in carbon emissions of 6.3 times its own weight, according to a studydone by Christoph Meinrenken, associate research scientist at the Earth Institute’s Research Program on Sustainability Policy and Management. Technology can provide energy efficiency measures that help combat climate change, but “consumption (and to a lesser extent population) growth have mostly outrun any beneficial effects of changes in technology over the past few decades,” according to a June paper. The research concluded that it is not enough simply to “green” consumption by buying more sustainably produced goods—it is essential to reduce consumption.....read onhttps://news.climate.columbia.edu/2020/12/16/buying-stuff-drives-climate-change/

This is because 45 percent of global greenhouse gas emissions come solely from the production of the things we use and buy every day. After basic needs are met, consumers begin buying items for social status; as people try to acquire more and more status, more and more expensive status products are needed. Producing all these things generates climate-changing greenhouse gas emissions. And in fact, across its life cycle, the average product results in carbon emissions of 6.3 times its own weight, according to a study done by Christoph Meinrenken, associate research scientist at the Earth Institute’s Research Program on Sustainability Policy and Management. Technology can provide energy efficiency measures that help combat climate change, but “consumption (and to a lesser extent population) growth have mostly outrun any beneficial effects of changes in technology over the past few decades,” according to a June paper. The research concluded that it is not enough simply to “green” consumption by buying more sustainably produced goods—it is essential to reduce consumption.....read on    https://news.climate.columbia.edu/2020/12/16/buying-stuff-drives-climate-change/
