The ecological value added tax (E-VAT) rests on a $13.2 trillion tax base, sufficient to fund the federal budget. The E-VAT is positively reinforcing, progressively forcing out polluting, depleting, and ecologically damaging items in order to maintain revenue. Varying E-VAT rates are developed over time, starting by using an industry’s average ecological performance by SIC code (Standard Industrial Classification) and then refining the ratings to reflect performance varying from the industrial average The E-VAT is good for business and largely self-enforcing due to the credit-invoice system.
