If you’ve been reading up on climate change and carbon footprints, you might want to know what a sustainable carbon footprint is for yourself.
In this guide, we look at what a sustainable carbon footprint per person (per year) might be, why that is, what the average carbon footprint of different countries are, and ideas to calculate and decrease carbon footprints.
What Might Be A Sustainable Carbon Footprint To Aim For Per Person, & Why?
- 3 tons of carbon dioxide emissions per person per year
- [the reason for this is] … At the average individual rate of 3 tons, yearly total global carbon dioxide emissions would be 21 gigatons. That’s equal to the global natural carbon sinks in the ocean, soil, biomass that keeps the amount of global carbon dioxide in the atmosphere level.
Ourworld.unu.edu also mentions:
- Trying to limit rising global temperatures to 1.5°C … means cutting CO2 emissions by 80% by 2050. This means that per person per year we would have to live a 3-tonne lifestyle
But ideally, if you read climate forecasts for the future (especially reports that discuss temperature targets of around 2 to 3 degrees celcius above pre industrial level), bringing carbon footprint as low as possible is ideal to minimise the effects and risks of greenhouse gases and climate warming as much as possible.
What Is The Current Average For Carbon Footprint Per Person Per Year – Globally, & By Country?
- … the global average is 4.5 tons (per person, per year)
- … the U.S. average per person is 17.5 tons a person per year
- … China is 6.4 tons a person per year.
We’ve previously outlined the countries that emit the most greenhouse gases and carbon dioxide.
How We Might Decrease Carbon Footprints On Global, & National Level?
We’ve previously outlined the industries that are responsible for emitting the most greenhouse gases and carbon dioxide.
From those findings, changes in the following areas of society in developed countries might bring about large decreases in the average carbon footprint:
- Energy Production – converting to renewable energy (like solar, wind, water etc.), or at least increasing their use as a supplementary power source to the current coal and gas power production
- Transport – increasing the use of electric and hybrid vehicles which utilise renewable or sustainable energy like electricity and hydrogen. And, slowly decreasing the use of fossil fuel based cars
- Agriculture – less use of of pesticides, fertilizers and particularly livestock based agriculture. More focus on plant based agriculture and incorporation of organic and sustainable farming practices to complement intensive farming practices
- Land Use & Deforestation – less clearing of forests and land. Less land conversion for farming. Create carbon sinks for carbon sequestration e.g. plant more trees and plant life
- Commercial & Residential – more sustainable energy and construction systems and materials are used on homes and dwellings and business buildings
- Industry/Business – factories and industry type buildings use more efficient and sustainable systems to operate
Developing countries might focus on learning from the mistakes of developed countries and build sustainable and renewable systems as soon as possible.
As an example of how current systems are weighing developed nations down, consider the carbon footprint of coal power plants in the US at the moment:
- the US coal generating plant “fleet” of 1,309 plants with a capacity of 343,757 megawatts produces 1.6 trillion kilowatt hours of electricity a year. This amounts to 5.32 tons of carbon per American per year all by itself. This represents 177% of the U.S sustainable carbon allowance.
How To Assess, & Lower Your Own Carbon Footprint
- Look at several carbon footprint calculators online, and look at all the factors of your life that have a carbon footprint to them (according to the different calculators)
- Estimate your carbon footprint with a few different online carbon footprint calculators to get an idea of you average
- Make steps in your life to adjust your footprint based on the different factors
- Educate others on how to lower their carbon footprint based on what you’ve found
One of the biggest ways you can slash your carbon footprint is with the food you buy and eat. Two general rules might be:
- Focus on more plant based foods as opposed to meat and dairy and animal based food products
- Don’t waste food – wasted food that you throw out has a carbon footprint too
Consider this from ourworld.unu.edu:
- the food we buy can add up to 20% of our carbon footprint. And this is just at first glance, because if we count up the related damage of deforestation from big agriculture, this brings the impact up to 30%.
