The following recommendations are part of the overall conclusions and recommendations of the OECD Environmental Performance Review of the Netherlands: • continue efforts to reduce emissions of NOx, particulate matter and NMVOCs (e.g. from transport, energy and industry) in light of persistent problems with concentrations of NO2, PM10 and ozone in some areas; implement the proposed NOx emission trading scheme; • pursue efforts to reduce ammonia emissions from agriculture; • provide small businesses with appropriate enforcement mechanisms to address long-term emission objectives, particularly for ozone precursors and priority substances; • continue to work towards increased energy efficiency; • expand the use of renewable energy sources (e.g. in municipalities and large firms)...
