How does YAYZY make money?

YAYZY sells carbon offsets to help people reduce their impact on the environment. YAYZY takes a small fee of £0.00125 per 1kg of carbon offsets. So, if you offset 1,000kgs YAYZY's fees will only be £1.25.

Our pricing model is cheap, easy to understand and transparent. Additionally, all carbon offset projects are treated equally which aligns interests.  

The fees are reinvested in the development of climate technology to help everyone reduce their carbon emissions, become carbon neutral and avoid environmental impact. We’re a for profit organization because we believe for profits have more tools to tackle the biggest problems humankind face.

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 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, Vitalmetrics, UK Government Guidelines for Carbon Footprint reporting, and United Nations International Civil Aviation Organization (ICAO).

In case you would like to learn more or contribute knowledge, please reach out to hello@yayzy.com

IF YOU ARE BRAVE, KEEP ON READING!

YAYZY developed the most advanced algorithm to calculate an individual’s carbon footprint. YAYZY Carbon Footprint Algo © uses data science to identify the sources of greenhouse gases emissions (GHG) within your payments data and match them against the best greenhouse gas intensity factor to get the most accurate and bespoke estimation of your personal carbon footprint.

In order to compute the most accurate carbon footprint estimation, the YAYZY Carbon Footpring Algo © matches payment information on a product, retailer or subcategory level against the appropriate greenhouse gas intensity factor. The more granular the data, the more accurate the estimation.

Money spent (£) * GHG emission intensity factor (kg of CO2e / £) = Carbon Footprint (kg of CO2e)

The YAYZY Carbon Footpring Algo © gets payments data from TrueLayer, an FCA regulated firm that provides an API to access data from your bank accounts and cards. Moreover, it gets itemized transaction information directly from retailers (with your consent), and direct integrations to lifestyle apps such as Uber, Ryanair, London Underground among others. YAYZY keeps integrating sources of payments data to increase the accuracy of the carbon footprint estimation.

YAYZY Carbon Footprint Algo © sources Green House Gas intensity factors from Vitalmetrics, greatly renown sustainability data provider, UK Government Guidelines for Carbon Footprint reporting, and United Nations International Civil Aviation Organization (ICAO).

The greenhouse gas (GHG) intensity factors are sourced mainly from VitalMetrics’ Comprehensive Environmental Data Archive (CEDA), a suite of environmental input-output (IO) databases that are designed to assist various environmental systems analyses, including life cycle assessments (LCA), carbon footprinting, water footprinting, and sustainable spend analyses. CEDA quantifies products’ natural resources use and environmental emissions throughout their life cycles by connecting input-output tables, which represent the entire supply-chain network of an economy.

For specific use cases we get additional user inputs to increase the accuracy of the carbon footprint estimation. As an example, in order to increase the accuracy of air travel, you can input departure airport, arrival airport, and cabin class, then the YAYZY Carbon Footprint Algo © will compute the carbon footprint using fuel consumption by aircraft type for your specific journey.

YAYZY follows best-in-class carbon footprint methodologies that are followed by publicly listed corporations and tailors it for you. In case you would like to learn more or contribute knowledge, please reach out to hello@yayzy.com

YAYZY has a strict methodology that involves doing research, standards and due diligence to guarantee we’re selling the best projects that provide long-term global benefits. We make sure the projects provide:

Additionality: the project reduces greenhouse gas emissions that would not be reduced through other incentives

Leakage prevention:prevent the leak or shift to another location or activity

Permanence: making sure green house gases are prevented from entering the atmosphere permanently

Verifiability: an objective third party that measures the performance).

However, don’t just take our word for it. We provide publicly available information that hopefully clarifies how each project is contributing towards climate change and links to our project manager websites and third party verifications. You can visit the climate compensation projects information page here.

How can YAYZY prove my contribution is going to the projects?

We publish certificates each month of how many tonnes of CO2 (‘carbon credits’) have been prevented from going into the atmosphere or removed from it.

About Offsets

What are carbon offsets and how do 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 hello@yayzy.com.

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 😊
