Options and Costs of Controlling Ammonia Emissions in EuropeG.KlaassenauthorAmmonia emissions contribute to acidification in Europe. The major emission sources are livestock and fertilizer use. This study presents the costs of controlling ammonia emissions in 33 regions in Europe. Abatement options include low nitrogen feed, stable adaptations, covering manure storage, cleaning stable air, and low ammonia applications of manure. Cost estimates are based on country- and technology-specific data. The structure of livestock population and fertilizer use mean that the cost of applying similar abatement options or techniques varies considerably. Allowing countries to choose their own mix of control options would be more cost-effective.1994RR-95-001. Reprinted from European Review of Agricultural Economics, 21:219-240 [1994].Monograph
