  • Measuring the impacts of the Nitrates Directive on nitrogen emissions

    The EU’s Nitrates Directive has led to significant decreases in nitrogen pollution in Europe, a new study suggests. Modelled scenarios with and without implementation of the Directive showed that it had resulted in a 16% reduction of nitrate leaching by 2008. These improvements could be further increased as implementation becomes stricter, the researchers conclude. More nitrogen is applied ...
