Invest 24%* of Your Net Income to Stop those Climate Monsters/ INVEST 24


Please INVEST 24%* of your business and your personal net incomes in enviro + nature orgs or zeroCO2 + sustainability projects that will help stop the climate monster heatwaves, wildfires and floods that may kill 45% of all multi-cellular life on Earth in the next 5 or 6 years.

*Consider 24% as your minimum climate investment, and that every additional percentage point will increase the chance of your and our survival. However, for those who need to reduce their INVEST percentage below 24% based on necessity see the sliding scale formula below.

INVESTing 24% of your personal and business net income in climate change fighting organizations and projects will pay for your carbon emissions at $800 per ton. $800 per ton is based the carbon price recommendations cited in the Basis for INVEST24 section below. $800 per ton may be the pricing needed to save our sweet+fun+dying biosphere. [Basis]

Note 1: An Intergovernmental Panel on Climate Change [IPCC] report has indicated that studies and models state that carbon emissions may need to be priced between $135 to $5,500 per ton by 2030 to prevent a 1.5C global warming. Funds could be used in forest, soil, ocean protection and restoration projects, and greenhouse gas reduction projects to ensure human and other species survival. [IPCC]

Note 2: UChicago: The ultimate cost of carbon. 'Ultimate cost' of carbon 1,000 times greater than cost to current generation. This study suggested the true cost could be between $10,000 to $750,000 per ton. [UChicago]

INVEST 24%* to save our exquisite home

Here is how to calculate and INVEST 24%* of your personal or business net income in the part of the biosphere that you are responsible for.

The sliding scale formula is for those who must reduce their INVEST 24% percentage based on financial necessity.

The above formulas can also be used to calculate and send out INVEST 24% bills to other businesses and individuals.

To calculate INVEST 24% for each net income amount::

1/ Start with your yearly business net income, or your personal net income, or another company's net income, or another person's net pay. This is net income before taxes.

If you are drawing on funds from an asset source, use that amount as your income.

2/ Multiply that net income by 24%.
+ For those with yearly net incomes under $60,000, if financially necessary, deduct up to 2% from the 24% for each $5,000 of net income that is less than $60,000.
+ We recommend that for those with yearly net incomes over $60,000, please add 2% more for each additional $5,000 of net profit over the $60,000.
+ We also recommend companies invest an additional 24% of the cost of labor and salaries. This will ensure that the carbon emissions generated by employees and staff incomes are covered too. [24% basis]

3/ Once the calculation for your business or for yourself, INVEST that amount in your favorite Environmental or Carbon Offset organization or greenhouse gas reduction project! [Our fave organizations below.]

When the calculation is for some other business or individual, send an INVEST 24%* bill to that business or individual.

4/ Yesss! Thanks for INVESTing 24%* in environmental organizations and emission reduction projects that will help keep this biosphere alive so we can all have more fun!

When your business INVESTs 24%*, we would like to help by regularly thanking and promoting your business via social media and beyond. So contact us when you get INVEST 24%* rolling. And, contact us for help getting your company started with INVEST 24%.

For personally INVESTing 24%*, we would like to thank you by sending some cool art or media to you every month via email or social media. Join us at XOEarth on facebook and tell us how your INVEST 24% is going, or tell us about your INVEST 24% contact us via email.

When the calculations are for another company or someone else, send an INVEST 24%*, Carbon Offset or Carbon Tax bill to that business or individual via social media and/or email - with a link to this page or, and a note from yourself about the bill.

For non U.S.A. residents, PPE [purchasing power equity] can be used to adjust these values in a fair way.

Go to our XOEarth Carbon Offset page to see why we think it is mighty fine to pay your carbon tax-offset to an organization that is not an "official carbon offset organization".

INVEST / Carbon Offset / Carbon Tax

Our planet cannot force us to INVEST or pay a Carbon Tax for the projects that are necessary to keep her and us alive. However, we should invest or pay those taxes anyway to help her not die and to keep us alive too.

The term 'carbon offset' usually sounds too optional to me.

I hope that everyone will say with pride, "I love to INVEST in my planet" or "I love paying My Carbon Tax".

For all the life, Stele Ely

Hello @ExxonMobil XOM, Have you paid your 2018 $546 million Carbon Tax bill? Please tell us! #ClimateChange

Example of a Carbon Tax bill and the note sent via email or Facebook

Hello and a Livable Earth to [ExxonMobil XOM / company name] ::

This is a copy of your 2018 [$546 million / or relevant tax] Carbon Tax bill.

Your Carbon Tax bill is an estimate of how much your business or you should pay to your favorite carbon offset organization.

Please pay your fair share to help slow down climate change and keep our planet livable.

If you have already paid your Carbon Tax bill, proudly announce it on your social networks so we can thank you and celebrate your eco logical commitment.

When you post about your Carbon Tax bill payment, include the name of the carbon offset organization and/or project that you funded, and link to that organization's acknowledgement showing that you have paid your Carbon Tax / carbon offset. Announce your Carbon Tax payment on your website too.

If you have not paid your Carbon Tax bill yet, I recommend or Other great organizations you can choose from are listed below.

Your payment will help fund projects that offset the dangerous impacts of your CO2 pollution on humanity and other species. These projects may include tropical and boreal reforestation, leaky natural-gas wells repair, abandoned-landfill methane gas collection, methane capture from abandoned farm waste ponds, protecting forests from illegal logging, small hydro funding, wind farm funding, energy efficiency programs, tree planting and waste energy capture.

A company Carbon Tax bill calculation is based on net income, estimated wages and salaries paid, World Bank CO2 emissions metrics, and a US$800 per tonne of CO2 emissions Carbon Tax. An individual Carbon Tax bill excludes wages and salaries paid in its calculation.

The US$800 Carbon Tax is lower than some recommendations. Sweden's 2017 rate is US$132 per tonn.

If you decide to use a more robust carbon offset calculator,, and other fine carbon offset organizations have calculators and free calculation services.

This Carbon Tax is in addition to your sustainability expenditures, renewable energy choices and sustainable investments. This is because, not only are your sustainability expenditures and investments the ethical thing to do, but they often save you money in the long run, increase customer loyalty and reduce your taxes.

This Carbon Tax is also additional because we all need to go big or risk the total loss of our biosphere - with some scientists saying as early 2035. [Go Big or No Home.]

To honor you for paying your Carbon Tax, I will continue to be one of your loyal customers or fans. I will also thank you for paying your Carbon Tax via my social networks and recommend your business.

Thank you, big time, for paying your Carbon Tax bill and helping fight climate change.

For all the life, Stele Ely and Co-Signers

Basis for INVEST and My Carbon Tax % - Summary

Company and individual Carbon Tax rates are based on two main factors::
+ The World Bank estimates there are .30 kilograms CO2 emissions per US$1 of Gross Domestic Product [GDP]. In general, one GDP dollar correlates closely to one net profit dollar.
+ An $800 Carbon Tax per tonne recommendation is XOEarth's Stele Ely's estimate based on information and recommendations from the Intergovernmental Panel on Climate Change [], ClimeWorks, United Nations, UCChicago [a paper by 3 professors], Climate Shock [book], and others.

Basis for INVEST24 and My Carbon Tax % - Details

+ The World Bank estimates that the global CO2 emissions from one US dollar [US$1] of GDP equivalent is .30 kilograms [2019]. [.325 kg worldwide average]
+ Based on the following resources, $800 a tonne was chosen by XOEarth director Stele Ely as a reasonable investment amount and/or price per tonne of carbon.
+ The price is about $1000 a tonne to permanently sequester carbon dioxide with ClimeWorks. ClimeWorks is CO2 capturing company whose mission and offsets have been endorsed, financially supported or purchased by Microsoft, Swiss Re, Shopify, Audi, GE, Christian Holzleitner [EU Commission], Dr. Oliver Geden [German Institute for International and Security Affairs (SWP)], Keith Tuffley [Citi], Allison Fleming [JP Morgan], Dr. Eli Mitchell-Larson [Carbon Gap] and Dominique Barker [Carbonplace].
+ The IPCC says that the price on carbon may need to jump above $1,000 a tonne sometime before 2030 and perhaps reach as much as $27,000 a tonne by the end of the century if we do not act now. [How High Does Carbon Need to Be? Somewhere From $20-$27,000 /] [The Intergovernmental Panel on Climate Change SR15 /] Based on various models, "...estimates for a Below-1.5°C pathway range from 135-6050 USD2010 tCO2-eq -1 in 2030, 245-14300 USD2010 tCO2-eq-1 in 2050, 420-19300 USD2010 tCO2-eq -1 in 2070 and 690-30100 USD2010 tCO2-eq -1 in 2100." IPCC SR15 Chapter-2]
+ The introduction of equity weights to the social cost of carbon (SCC), would increase the estimated SCC from 79 (11-186) to 291 (83-592) US$ per tCO2. [Social cost of carbon under a carbon-neutral pathway]
However, also stated in this study, "the uncertainty in SCC estimates should be even greater than the above range demonstrated in this study, as a meta-analysis showed that adjustments to the damage function could increase the SCC estimates by a factor of three to five (Howard and Sterner 2017)." [Social cost of carbon under a carbon-neutral pathway]
Therefore, for example, on the high end, the SCC could be as high as $592 x 5 = $2960 per ton of CO2.
+ The envelope of worldwide marginal abatement costs for 1.5°C-consistent pathways reported in the Chapter 2 is 135-5500 USD2010 tCO2 -1 in 2030 and 245-13000 USD2010 tCO2 -1 in 2050, which is between three to four times higher than for a 2°C limit. IPCC: SR15: Chap4 Strengthening and Implementing the Global Response
+ But even if we assume a very low $12.50 per tCO2, some of us will have to make up for the actions of a lot of people who are destroying it. So here is another way to look at it, to cover the CO2 emissions of 63 other people as well as one's own at $12.50 per tCO2 is still about $800 a ton. Even though this may not sound fair, what is the price you would pay for your own survival.
[This $800 per ton is based on a carbon offset price of $12.50 per ton x 64 people. One of those 64 is you and 63 are for those who do not invest in carbon offsets or carbon reduction non-profit projects or organizations. is a reputable organization that is pricing its carbon offset at $12.50 per ton. $12.50 is close to the cost that other carbon offset organizations charge. And by the way, the author of 'DrawDown' and 'Regeneration' Paul Hawken recommends paying 5 times your offset in order contribute to the regeneration of Earth's ecosystems. [DrawDown]
+ UChicago: The ultimate cost of carbon. 'Ultimate cost' of carbon 1,000 times greater than cost to current generation. $100,000 per ton of carbon is the study's best-estimate value of ultimate cost per ton of C. The study's range was $10k to $750k per ton. It also was based on business as usual for the next 80 to a few hundred years. Two of its authors are David Archer and Edwin Kite.
+ Climate change will ultimately cost humanity $100,000 per ton of carbon, scientists estimate.
+ A United Nations paper says that carbon priced at US$100 per tonne would encourage sustainable energy use and pay for sustainable carbon reduction projects. UN Emissions Gap Report / by UN Environment authors
+ Climate Shock book and/or presentations / by Gernot Wagner and Martin L. Weitzman say that carbon should be priced at least US$40 and up to US$400 a ton.
+ Forbes writer Tim Worstall says that a company's fraction of the GDP can be assumed to be the net profit of the company, plus employee's wages and admin's compensation.
+ Labor costs vary greatly by industry - but in general it seems runs from 10% to 30% of gross income, and roughly 100% to 400% of net income.
+ If one were to assume that businesses are responsible for 'collecting' and paying the Carbon Tax on the labor [because labor cost are a segment of GDP /], that would increase the Carbon Tax paid by the business. For example, if the labor cost for a company is 200% of net income, the Carbon Tax rate for businesses would be double the base Carbon Tax rate here on the INVEST page - therefore 24% X 2 = 48%.
+ When we say "labor costs" we are including all payments to labor for work done, employee wages, contract labor wages, administrative salaries and officer salaries.
+ Because My Carbon Tax is calculated before taxes, that means that the company or individual is also paying for their government's share of the carbon offset on that GDP associated money.

Basis for the INVEST and My Carbon Tax % - Formulas

This initial carbon tax rate is calculated for the $60,000 net income level. Rate adjustments for levels above and below this $60,000 is described further below.

US$800 carbon tax per 1000 kg (1 tonne), so
US$800 per 1000 kg = US$.80 carbon tax per 1 kg, so
US$.80 carbon tax per kg X .3 kg CO2 emissions per US$1 GDP = 0.24 per US$1 of GDP, so
0.24 per US$1 of GDP is the 24% tax.

So, if businesses are asked to collect and INVEST the labor part of their GDP,
Net income before taxes (of a company) X 2 (if we were to assume labor costs at 200% of businesses net income) = carbon tax is business net income X 2, so
[Business My Carbon Tax rate on net income] 2 X 0.24 = 0.48 [48%]

However, for the individual, their INVEST or Carbon Tax percentage is 24% because it is assumed here that most businesses are not paying a voluntary INVEST or Carbon Tax of 48% as calculated above. If a business does pay for the employee's INVEST or Carbon Tax - as well as their own - then the individual would NOT be obliged to pay any INVEST or Carbon Tax. Also here, we are not asking the individual to pay the business's share of the carbon tax. So,
[Individual INVEST or Carbon Tax rate on net income] 1 X 0.24 = 0.24 [24%]

Further, if a business were to require an individual to INVEST or pay their carbon offset tax, the business would not have to pay the individual's share.

Also, to prevent the tax from being regressive, the tax rate increases as income level increases above $60,000, and, the tax rate decreases as income level decreases below $60,000.

Therefore, add 1% to those rates for each additional $100,000 of net profit up to $3,000,000. Plus, deduct 2% from individual rate for each $5,000 of net profit that is less than $60,000. [Please prorate the rate increments.]

Another justification for the rate increments is that the IPCC says that if we do not act now, the price on carbon may need to jump above $1,000 a tonne sometime before 2030 and perhaps reach as much as $27,000 a tonne by the end of the century if we do not act now.
