## How do I calculate my footprint?

How To Calculate Your Carbon Footprint

- Multiply your monthly electric bill by 105.
- Multiply your monthly gas bill by 105.
- Multiply your monthly oil bill by 113.
- Multiply your total yearly mileage on your car by .79.
- Multiply the number of flights you’ve taken in the past year (4 hours or less) by 1,100.

**What is the ecological footprint calculator?**

Global Footprint Network’s Footprint calculator results represent the amount of land and sea area needed to provide the resources a person needs (food, shelter, etc.), and absorb their carbon dioxide emissions. The Ecological Footprint is expressed in global hectares.

### How is Earths Overshoot Day calculated?

The Earth Overshoot Day is calculated by dividing the planet’s biocapacity (in global hectares) by humanity’s ecological footprint (in global hectares) and multiplying by the number of days in a year, which is 365.

**How do you calculate your carbon footprint worksheet?**

Go to: http://www3.epa.gov/carbon-footprint-calculator/ and when prompted, enter the number of people in your household along with your zip code. Then click “Get Started” and navigate through each section of online calculator to complete the worksheet.

#### How many planets does your footprint need?

According to the Global Footprint Network, which estimates Earth Overshoot Day each year, we now need 1.5 Earths to satisfy our current demands and desires.

**What other factors should the calculator have taken into account when determining an ecological footprint?**

The calculation of the ecological footprint takes into account the following two factors:

- The Earth’s biocapacity, i.e. the planet’s capacity to produce resources;
- Human activity and its ecological impact, i.e. the resources consumed by humans and their waste.

## What is the estimated Earth Overshoot Day for 2021?

July 29th

In 2021, Earth Overshoot Day falls on July 29th, meaning that between January 1st and July 29th, humanity’s demand for biological regeneration is equivalent to the planet’s entire annual regeneration. In 2020, Earth Overshoot Day fell on August 22nd.

**What is Earth’s Overshoot Day for 2022?**

May 22, 2022 (International Day for Biological Diversity) is the deadline to submit your calculation methodology and result below. The winner, as well as the date of Earth Overshoot Day 2022, will be announced on June 5.

### How many Earths would it take to sustain the average American?

Here’s how we calculate that, using the United States as an example: The Ecological Footprint for the United States is 8.1 gha per person (in 2018) and global biocapacity is 1.6 gha per person (in 2018). Therefore, we would need (8.1/ 1.6) = 5.1 Earths if everyone lived like Americans.

**What are the components in calculating the ecological footprint of a country?**

The Ecological Footprint tracks the use of productive surface areas. Typically these areas are: cropland, grazing land, fishing grounds, built-up land, forest area, and carbon demand on land.

#### How do carbon footprint calculators work?

The calculator divides mileage by the car’s fuel efficiency to determine annual fuel usage. This figure is then multiplied by the emissions factor of gasoline or diesel fuel, which converts it to pounds of CO2. For air travel, some carbon calculators ask for an annual estimate of mileage.
