Therefore, when the carbon footprint is reported within the context of the total Ecological Footprint , the tonnes of carbon dioxide emissions are expressed as the amount of productive land area required to sequester those carbon dioxide emissions. This tells us how much biocapacity is necessary to neutralize the emissions from burning fossil fuels.
Measuring the carbon footprint in land area does not imply that carbon sequestration is is the sole solution to the carbon dilemma. It just shows how much biocapacity is needed to take care of our untreated carbon waste and avoid a carbon build-up in the atmosphere. Measuring it in this way enables us to address the climate change challenge in a holistic way that does not simply shift the burden from one natural system to another. In fact, the climate problem emerges because the planet does not have enough biocapacity to neutralize all the carbon dioxide from fossil fuel and provide for all other demands.
This framework also shows climate change in a greater context—one which unites all of the ecological threats we face today. Climate change, deforestation, overgrazing, fisheries collapse, food insecurity, and the rapid extinction of species are all part of a single, over-arching problem: Humanity is simply demanding more from the Earth than it can provide.
By focusing on the single issue, we can address all of its symptoms, rather than solving one problem at the cost of another. Also, it makes the self-interest to act far more obvious. Paris Climate Agreement.

The complicating factor in eating locally happens when you start to consider how the food got to you, not just from how far away it came.
Tomatoes brought a short distance to a farmers market by truck, or shipped further to the grocery store by a train, could release similar emissions. The transportation you take to get your tomatoes, and bring them home, also matters. What about local meat versus imported vegetables? Eating only locally grown food for one year would save the greenhouse gas equivalent of driving 1, miles, but eating just one vegetarian meal a week for a year saves miles more than that , according to one study from researchers at Carnegie Mellon.
How about organic? The study found that organic systems use less energy than conventional ones, but they often require more land and, therefore, emit similar greenhouse gas emissions. This is a big one : on average, Americans waste around 40 percent of the food they buy. Luckily, there are simple solutions to lower your food waste and these tips will save you money, too.
What to Eat On. Skip the disposable dishes and wash your dinnerware instead. Washing dishes, whether it is by hand or in a dishwasher, is likely to be more environmentally friendly than using disposable ones assuming your dishwasher is energy efficient. If you do need to use disposable plates, bowls and cutlery, there are climate-friendly options look for compostable or biodegradable options.
If you order takeout, wash and reuse the plastic containers that food often comes in. In the average American home, 25 percent of energy is used to heat spaces, 13 percent is used to heat water, 11 percent is used for cooling and the remainder is spent on appliances, according to estimates from the Natural Resources Defense Council. Making even small changes to these can make a big difference, said Noah Horowitz, a senior scientist and director of the N.
This calculator can help you work out your energy usage before and after you make these changes. Americans generate about roughly million tons of trash a year , million tons of which ends up in landfills and incinerators, according to a report from the E.
But much of the waste that can be recycled still ends up in landfills. Small changes to the insulation and design of your home — from do-it-yourself hacks to building changes — can help you reduce your carbon footprint at home. Buying less is the first step.
Beyond that, there are simple ways to reduce the impact from your purchases. According to the World Resources Institute, 20 items of clothing are manufactured per person, per year. As the price of our clothes drops, the environmental and human costs increase. In addition to changing your day-to-day habits, exercising your rights as a citizen is one of the most significant things you can do to help the planet.
Taking climate change into consideration when you vote is a good start. Here are some other tips:. Originally from Australia, she has a master's degree from Columbia Journalism School and has also reported for publications including The Atlantic, Quartz and Vice Magazine. By Livia Albeck-Ripka. What Is a Carbon Footprint? You will need to know the following: Approximately how many miles you travel by car, bus, train and plane.
The energy usage in your home. How much you spend shopping. The composition of your diet. A new book presents potential solutions. Can you figure out which ones are top ranked? On the Road, in the Sky One of the most effective ways to begin thinking about how to reduce your carbon footprint is to reconsider how much, and how often, you travel.
Drive Less In November carbon dioxide emissions from transportation surpassed emissions from electricity generation as the top source of greenhouse gases. So, when you do, here are some tips to make your trip more climate-friendly: Go easy on the gas and brakes — driving efficiently can help to reduce emissions.
Regularly service your car to keep it more efficient. Check your tires. Keeping tires pumped correctly can reduce emissions. West said. Air conditioning and intensive city driving can make emissions creep up. Cut down on these as often as possible. Use cruise control on long drives — in most cases, this can help to save gas. Buying a New Car? The following can help: Search for cars here , where they are rated by efficiency.
Think about where you will be charging up. How efficient hybrid and electric cars are also depends on what state you live in — different states rely on fossil fuels to different degrees.
Weigh up both production and use emissions using this app. Making electric cars has a carbon footprint, too. Look for the Smart Way certification. Remember: Cars with lower emissions can often end up costing less to operate. Fly Less Fly often? July 27, On Your Plate Globally, emissions are linked to what we put on our plates.
Eat Less Meat While food systems are complicated, and research is still evolving on what the most environmentally-friendly diet is, experts mostly agree that cutting down on meat , and red meat in particular, is a better choice for the environment. Weighing Your Options When it comes to food, most greenhouse gas emissions happen during production, rather than transportation : What you eat is more important than where it comes from. Waste Less This is a big one : on average, Americans waste around 40 percent of the food they buy.
Be wary of bulk. Account for the right amount of food for the number of people eating, and adapt recipes to your needs. Get creative. Reuse leftovers instead of tossing them. Extend the life of your food, including additional portions, as well as produce like fresh herbs, by freezing them properly.
