The Case for Environmental Tax Shifting: The Polluter Pays Principle |
|||||
s economists have long known, we use less of what is taxed and more of what is not. The "polluter pays principle" means that the industry or individual adversely impacting the environment pays the costs of reversing that damage. It is a market approach to environmental protection and works to complement traditional government regulation. The costs of mitigation are internalized by the industry sector causing the damage, ultimately encouraging prevention through marketplace.45, 46
The cost of chemical use to the environment and human health has not been borne by agriculture. "The real costs ... whether that is nutrient enrichment and fish declines in the Gulf of Mexico from fertilizer runoff, or bird declines due to pesticide use" are not paid by the system.47
Most Americans would actually support increased charges. An opinion poll conducted by the Center for Science in the Public Interest (CSPI) in 1995 found that 76 % of Americans support levying a small charge on agricultural uses of pesticides to fund sustainable agriculture. Eighty-six percent think federal and state agencies should teach farmers to use fewer pesticides.55 A separate 1998 survey of registered voters found that 64 % favored pollution taxes and 72 % favored the restructuring of economic policies that harm the environment.56 Some states have already taken small steps toward implementing a policy of using taxes to fund programs promoting sustainable agriculture. California, Minnesota, and Iowa have each adopted nominal pesticide taxes (0.3 - 1.5 % of sales) and are directing some of those funds towards grant programs that encourage more research and the adoption of sustainable practices. Most states charge at least a nominal fee per ton of synthetic fertilizer to pay the cost of monitoring its use, and some states also use these funds for educational programs. A number of European countries have implemented or are considering larger taxes of up to 30 % to fund education and research and to actively discourage the use of agricultural chemicals.57, 58 Currently, twenty-nine state governments exempt agricultural chemicals from sales taxes losing nearly $700 million in uncollected revenue. The exemptions, thereby implicitly encourage chemically-intensive agriculture while putting alternatives like organic growing at a competitive disadvantage due to the need, for instance, to pay for more labor-intensive weed control instead of relying on herbicides.59 These exemptions are unfair to the other industries that are paying for the costs associated with their environmental and health impacts, to the people who are experiencing the health consequences of agri-chemicals, and to the taxpayer ultimately footing the bill for environmental clean-up. Building on the ‘polluter pays' principle taxing agri-chemical use is clearly one of the simplest mechanisms to fund the transition to more environmentally-friendly methods of farming.
