In 2015, diesel vehicles made up 42 percent of the total fleet of passenger vehicles in the EU. Although new Euro 6d-temp vehicles meet current emissions standards, the older diesel vehicles that remain on the roads continue to have an important impact on air pollution. Some cities are introducing access restrictions to the older, more polluting vehicles. So, what are the options for owners of older diesel vehicles?<\/p>\n\n\n\n
As<\/a>, EU Member States regularly surpass EU NO (2) reducing pollutant emissions from diesel vehicles has been an area of particular interest for policymakers. We take a look at scrapping schemes and retrofitting options as ways to accelerate the reduction of emissions from older diesel vehicles.<\/p>\n\n\n\n Scrapping schemes are necessary to accelerate the replacement of older diesel vehicles and meet emission reduction goals.<\/p>\n\n\n\n Scrapping schemes encourage drivers of older diesels to switch their car or van to a more environmentally friendly vehicle, such as a Euro 6d-temp diesel, through many incentives, such as compensation, part-exchange or fiscal benefit.<\/p>\n\n\n\n An example of a successful scrapping scheme is the French \u201cprime \u00e0 la casse\u201d system where drivers of old diesel cars receive a compensation of up to \u20ac2,000 when switching to new diesel vehicles. Since January 2018, this initiative has already helped to replace 60,000 vehicles in France. Several car manufacturers are offering such schemes across Europe as well.<\/p>\n\n\n\n Accelerating the scrapping of old vehicles and replacing them with Euro 6d-temp vehicles which meet the latest emission standards is an efficient answer to tightening air quality standards and emission reduction regulation in cities.<\/p>\n\n\n\n Scrapping schemes and retrofitting are steps to rapidly improving air quality, health and mitigating the environmental impact in Europe<\/em><\/strong><\/p>\n\n\n\n A key development in preventing harmful emissions has been the Diesel Particulate Filter (DPF), which traps soot particles. All new diesel cars in the EU have been fitted with this technology since 2011. However, technologies to reduce nitrogen oxide (NOx) emissions have been broadly introduced only later.<\/p>\n\n\n\n Retrofitting older diesel vehicles with systems that reduce NOx exhaust emissions is a viable solution to today\u2019s air pollution challenge, with some options reducing emissions by up to 70%.<\/p>\n\n\n\n Selective Catalytic Reduction (SCR) systems are seen as an efficient technology necessary to achieving emission standards. They work by adding ammonia \u2013 either in the form of AdBlue\u00ae<\/sup><\/a>, a liquid NOx reducing agent, or directly as a gas, using cartridges \u2013 to the exhaust gases. This then reacts in a catalytic converter with the nitrogen oxides coming from the diesel engine to release harmless nitrogen and water vapour at the tailpipe.<\/p>\n\n\n\nHow do scrapping schemes work?<\/h4>\n\n\n\n
