# How much CO2 is released for every gallon of gas used in cars?

## How much CO2 is released for every gallon of gas used in cars?

Every gallon of gasoline burned creates about 8,887 grams of CO2, and there are one million grams per metric ton.

## How much CO2 is produced from a gallon of gas?

About 19.64 pounds of carbon dioxide (CO2) are produced from burning a gallon of gasoline that does not contain ethanol.

How is 1 gallon of gasoline 19 pounds of carbon dioxide?

If each carbon atom in a gallon of gasoline becomes 3.6 times heavier when converted to carbon dioxide after combustion, then the 5.3 pounds of carbon in a gallon of gas becomes just over 19 pounds (8,650 grams) of carbon dioxide.

Which fuel has the most carbon?

The heat content or the amount of energy produced when a fuel is burned is mainly determined by the carbon (C) and hydrogen (H) content of the fuel….How much carbon dioxide is produced when different fuels are burned?

Coal (anthracite) 228.6
Diesel fuel and heating oil 161.3
Gasoline (without ethanol) 157.2
Propane 139.0
Natural gas 117.0

### How does 1 gallon of gas become 20 lb of CO2?

When gasoline burns, the carbon and the hydrogen in the gas molecules separate. So the carbon in a gallon of gasoline (weighing 6.3 pounds) weighs 5.5 pounds (. 87 x 6.3 pounds = 5.5 pounds). So, multiply the weight of the carbon times 3.7, which equals 20 pounds of carbon dioxide!

### How much CO2 is emitted when natural gas is burned?

Natural gas is a relatively clean burning fossil fuel About 117 pounds of carbon dioxide are produced per million British thermal units (MMBtu) equivalent of natural gas compared with more than 200 pounds of CO2 per MMBtu of coal and more than 160 pounds per MMBtu of distillate fuel oil.

How many pounds of carbon dioxide does a human produce?

So breathe easy. The average human exhales about 2.3 pounds of carbon dioxide on an average day. (The exact quantity depends on your activity level—a person engaged in vigorous exercise produces up to eight times as much CO2 as his sedentary brethren.)

What is the biggest contributor to global warming?

Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.

## What is the largest contributor to greenhouse gases?

The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks.

## What does 1 gallon water weigh?

8.34 pounds
One US liquid gallon of fresh water weighs roughly 8.34 pounds (lb) or 3.785 kilograms (kg) at room temperature.

What does 1 gallon of gas weigh?

It seems impossible that a gallon of gasoline, which weighs about 6.3 pounds, could produce 20 pounds of carbon dioxide (CO2) when burned. However, most of the weight of the CO2 doesn’t come from the gasoline itself, but the oxygen in the air.

How many trees does it take to offset a ton of CO2?

We used carbonfootprint.com to find how many tonnes of CO2 each trip would generate. Trees for Life calculates 6 trees offset 1 tonne of CO2. So 1 Tree = 0.16 tonnes CO2.

### How much carbon is in a gallon of gasoline?

Next, we need to know how much of the weight of the gasoline is just the carbon. Gasoline is about 87% carbon and 13% hydrogen by weight. So the carbon in a gallon of gasoline (weighing 6.3 pounds) weighs 5.5 pounds (.87 x 6.3 pounds = 5.5 pounds).

### How does burning a gallon of gas produce carbon dioxide?

Burning 6.3 pounds of gasoline produces 20 pounds of carbon dioxide. Huh!? Here’s how. Most of the weight of carbon dioxide (CO 2) comes from the two oxygen atoms (the O 2 ). Gasoline molecules are made of carbon and hydrogen atoms all bound together. When gasoline burns, the carbon and the hydrogen in the gas molecules separate.

How to calculate the amount of CO 2 in gasoline?

For reference, to obtain the number of grams of CO 2 emitted per gallon of gasoline combusted, the heat content of the fuel per gallon can be multiplied by the kg CO 2 per heat content of the fuel. This value assumes that all the carbon in the gasoline is converted to CO 2 (IPCC 2006).

Where does most of the weight of CO2 come from?

Most of the weight of carbon dioxide (CO2) comes from the two oxygen atoms (the O2). Gasoline molecules are made of carbon and hydrogen atoms all bound together. When gasoline burns, the carbon and the hydrogen in the gas molecules separate. Two hydrogen atoms combine with one oxygen atom to form H2O, or water.
