Corperations, unsurprisingly, have the biggest carbon footprints of all.If you’re trying to reduce your carbon footprint, think about that next time you leave the lights on. NuEnergy says that fossil fuels and coal are the source of 67% of generated electricity.And that’s not just recycling, that’s also simply by buying products with less packaging and refusing plastic bags at the grocery store. For every 10% of waste reduction, you can avoid 1,200 pounds of CO2e, according to the Center for Sustainable Systems. Reducing waste, surprise surprise, actually makes a difference.Speaking of your commute: Transportation is one of the biggest producers of CO2, only behind electricity generation, according to environmental advocacy group NuEnergy.The center found that when driving 50 mph or more, every 5 mph increase is equivalent to paying between 20 and 40 cents more per gallon. And the fact sheet points out that if you follow the speed limit, not only will you not get a ticket, you’ll also improve your fuel economy and, by extension, shrink your carbon footprint through greater fuel efficiency.The production of food accounts for 83% of emissions, and its transportation accounts for 11%. The center found that on average, one American household emits 8.1 metric tons of CO2e each year through food consumption alone.Vegetables, meanwhile, contribute a mere 4.9%. Dairy products like cheese and yogurt contribute almost 19% of greenhouse gases emitted – even worse than poultry, seafood and eggs, which only contribute 14% of greenhouse gases. Meat isn’t the only problem, the center says.And yes, all that ends up in the atmosphere. In 2016, they produced 170 million metric tons in CO2e of methane, according to a carbon footprint fact sheet compiled by the Center for Sustainable Systems at the University of Michigan. That’s because animals like cattle, sheep and goats produce a lot of methane gas.
