pollution abatement costs

基本解释

Rather than a regulatory system with uniform effluent limitations, it may be preferable to have a variable standard that would concentrate pollution abatement where it costs the least.
制定各种各样的花费成本最少而又达到减污效果最佳的可变标准或许是最好标准，而不是统一的污染限制管制体制。
A World Bank study in 2003 showed that with very few exceptions companies did not choose to invest in poorer countries in order to avoid the costs of pollution abatement in richer ones.
2003年世界银行一项研究表明，那些更加富有国家的绝大多数公司愿意在贫穷国家投资，以避免其付出高昂的环境代价。
