29 Apr 2024 · 7
We’re in a climate emergency. To limit average global temperatures from rising by more than 1.5°C, the goal indicated at the 2015 Paris Climate Conference, all parties — citizens, governments, organizations, individuals, and companies — must do their part to reduce their climate footprint. Luckily, it’s now easier than ever before for everyone to participate with carbon footprint tracker apps.
Whether you’re a finance or  at a company or an individual ambitious about your personal carbon emissions, look no further than this article to find the best carbon footprint tracker app to support your journey.

What does a carbon calculator app do?

A carbon footprint tracker app helps individuals, companies, and organizations make informed decisions about their carbon consumption by calculating and measuring their carbon footprint.
Knowing the carbon emissions from your lifestyle or business is the critical first step in understanding impact and fighting climate change. However, tracking your carbon footprint is complex. It’s often difficult to track it accurately (either as an individual or at a company level).
Therefore, it’s essential to work with a carbon footprint tracker app that employs proven methodologies when calculating emissions.
James Dent, Head of Sustainability at TravelPerk, explains the importance of tracking your carbon emissions: 
"Any credible net-zero climate plan needs to be backed up by data. It's very difficult for all companies to have full end-to-end visibility of their Scope 3 impact and GHG emissions. Having calculation methodologies, emission factors, and reporting frameworks that are consistent across the globe is extremely important to help progress on the path towards a more sustainable future."
