Recent studies and reports have been outlining the carbon footprints of cities worldwide.
In this guide, we list some of the cities with the largest carbon footprints.
Identifying the top greenhouse gas emitting cities is a good start in being able to come up with solutions for climate change mitigation and adaptation.
It’s worth noting that the carbon footprint of a city is one also of the factors that contributes to how sustainable or green a city is.
Summary – Cities With The Largest Emissions Footprints
City carbon footprints can be measured in total emissions, and also per capita emissions
What we also list below is that measuring emissions for a particular city can be complex and time consuming – so, data is always a guide only
Cities That Emit The Most Greenhouse Gases & Carbon Dioxide (In Total)
The top 30 cities with the largest carbon footprints (in total carbon dioxide emissions) are:
Hong Kong SAR
Country Of Singapore
Cities That Emit The Most Greenhouse Gases & Carbon Dioxide (Per Person/Per Capita)
The top 30 cities with the largest carbon footprints per capita/person are:
Hong Kong SAR
Mohammed Bin Zayed City
Country of Singapore
A Note On Calculating The Carbon Footprints Of Cities
Calculations for carbon footprints are a guide only because of the data that might be included, and because of how complex and time consuming calculations can be.
For example, carbon footprints can be calculated with emissions from the production stage of goods and services (for example manufacturing a car), and also emissions from the consumption stage of goods and services (for example driving the car, getting it repaired, maintaining it, etc.).
Some footprints only include one stage of the carbon lifecycle.
Also note that energy can be consumed and emissions produced within the city, off site at power plants, and off site at other locations (like people taking plane travel from the city to another location, waste being taken from the city and disposed of at landfills, and so on).
Some calculations might only include emissions within the city.
Emissions can also be imported and exported between cities with the exportations and importation or outsourcing of goods and services.
There’s many calculations and variables that can make up a 100% accurate/precise city carbon footprint.
Always look at exactly what data and calculations a footprint involves to get an idea of what it’s representing.
