The 5 Best Carbon Footprint Calculator Apps & Websites

In recent years, the drive for governments, businesses, and everyday people to reduce their carbon footprints has become a hot topic. In South Africa, the government recently set a new and stronger 2030 emissions target range, along with some regulatory changes. But it’s not only up to the government and big business to reduce emissions; every citizen has a role to play in creating a greener future. That’s why we’ve put together a list of the best carbon footprint calculator apps, tools and websites to help you track your carbon footprint and improve your way of living.

1. United Nations Carbon Offset Platform

The United Nations Carbon Offset Platform is an e-commerce platform that allows companies, organisations or regular citizens to purchase units (carbon credits) intended to compensate for greenhouse gas emissions, or to simply support action on climate.

Part of the UN Carbon Offset Platform, the UN carbon footprint calculator is a simple tool to help you understand how much carbon you’re using week to week. It takes into account:

  • Transport habits and patterns
  • The country you live in
  • The number of people in your household
  • Energy source
  • The size of the house that you live in 
  • Lifestyle, diet, and other factors

Taking these factors into consideration, the carbon footprint calculator then shows you

how much your home, energy usage and food intake can affect the environment. It also indicates whether your annual emissions are more or less than the world average.

Along the way, the tool also provides helpful facts to help you understand how to minimise your carbon footprint. You can also set a weekly goal to see how you measure up against friends and compare your own emissions from week to week.

2. Klima

Klima is a personal carbon footprint app designed to make personal action radically easy. It claims to offer one of the most advanced and precise carbon calculators available.The app offers a number of features to help you neautralise your carbon emissions and learn how to shrink your own footprint sustainably:

  • Calculate your carbon footprint and easily understand the effects of your lifestyle
  • Fund science-based climate projects that capture or prevent the same emissions elsewhere to offset the carbon emissions you can’t avoid yet
  • Learn how to reduce your carbon emissions sustainably by focusing on the lifestyle choices that have the highest carbon impact
  • Multiply your impact by getting more people involved

One of the main features of the Capture personal carbon footprint app is the GPS-based algorithm that automatically tracks your transportation emissions, whether you’re taking a car, bus, plane, or bicycle. Capture can use this GPS information to predict your carbon emissions & provide you insights into your carbon footprint caused by travelling.

How it works:

  1. Download the app
  2. Create an account by answering a few questions about your lifestyle
  3. Set a monthly target based on a 7.6% reduction (the amount we need to decrease emissions between now and 2030 to keep a 1.5 degree warming target)
  4. Switch on GPS tracking (never shared without explicit permission
  5. Review your live CO2 emission information whenever you want
  6. See the breakdown from your different mobility choices
  7. Choose your favourite verified CO2 offsetting project for an optional offset of your carbon at the end of every month

Why use a personal carbon footprint app? 

While human advancements may have helped get us into this mess, innovations in technology such as carbon footprint calculator apps are also helping us track carbon emissions and use the data to make smarter, more environmentally sound decisions. This is a very promising step in making our planet more sustainable and livable for years to come. 

According to Klima, 72% of carbon emissions are addressable by consumer behaviour. At scale, individuals have the power and potential to reduce carbon emissions and make a real impact. From our daily routines, to how we shop and travel, we all have a role to play in forging a better future. We hope that you’ll become part of the solution by using these simple, helpful carbon footprint apps.
