What’s my carbon footprint?
Your carbon footprint is the amount of carbon dioxide and other greenhouse gases (GHG) released into the atmosphere as a result of your activities and lifestyle. Your carbon footprint is the best estimate you can get of your impact to climate change. It is measured in kilograms of Carbon Dioxide equivalent (kg CO2e).
What’s should my carbon budget be?
Your carbon budget is the amount of greenhouse gases, measured in kilograms, that you set as your individual upper limit per month. For your reference, an average British person emits 800 kilograms of greenhouse gases per month. In order to be below the global budget of a temperature increase of 2°C by 2050, every person on earth should be limited to 191kg per month (2.3 tonnes per year). However, we should all aim to be climate positive and help remove carbon dioxide from the atmosphere.
How does the carbon footprint calculation work?
Your carbon footprint is related to your lifestyle. YAYZY developed an innovative algorithm that uses your bank account transactions to calculate your carbon footprint. To calculate your monthly carbon footprint, we estimate the emissions of each of your transactions and we sum it all together.
The carbon footprint of each transaction results from multiplying the amount spent of each payment transaction times the corresponding greenhouse gas (GHG) emissions intensity factor on a product, company or sub-category level.
Money spent * GHG emission intensity factor = Carbon Footprint
YAYZY Carbon Footprint Algo © sources Green House Gas intensity factors from multiple renown sustainability data providers such as UK Government Guidelines for Carbon Footprint reporting, Exiobase and United Nations International Civil Aviation Organization (ICAO).

What are carbon offsets and how they fight climate change?
A carbon offset is a reduction in emissions of carbon dioxide and other greenhouse gases that compensate for emissions made elsewhere. Carbon offsets are created by carbon offset organizations that prevent and remove carbon emissions from the atmosphere and verified by greatly renowned institutions.
YAYZY works with the leading organizations across the planet that create the biggest positive impact on the environment and on society. Projects consist on protecting forests, using agriculture methods that remove carbon, clean energy generation and capturing carbon straight from the air. Check YAYZY’s carbon offset projects in the Offsets screen of the YAYZY app.
In case you want to learn more or suggest adding an innovative and impactful carbon offset project please reach out to firstname.lastname@example.org.
Is it good enough to only offset my carbon footprint to fight climate change?
No! 🙉 Offsetting your carbon footprint do help prevent emissions and remove carbon from the atmosphere. However, the best solution to fight climate change is avoid emitting carbon and other greenhouse gases on the first place.
The biggest contributors to your personal carbon footprint are fossil-fuel heavy transportation such as flights, fossil-fuel heavy electricity and red-meat-intensive meals. So, to help fight climate change try reducing your flight travel, switch to a green electricity provider and introduce a meat and dairy free day per week. Also help spread out knowledge with your family and friends.
Try to reduce your footprint by fine-tuning your lifestyle and shopping wisely. And become climate neutral or climate positive by offsetting the purchases you can’t avoid like flying back home for Christmas. YAYZY is here to help 😊
