Provides distinct visual \u2018layers\u2019 for more than 20 individual sources (e.g., taxis, Transport for London buses, commercial gas), as well as grouped sources (e.g., all diesel vehicles).<\/li>\n<\/ul>\nThe modelled data, which takes into account factors like wind and weather, is available on a 10 metre grid across London and provides the annual pollution concentrations experienced at 1m above ground level.<\/p>\n
Which sources are included?<\/strong><\/p>\n\nRoad transport<\/em>: Cars, buses, lorries, etc. and particularly those that run on diesel fuel.<\/li>\nOther transport<\/em>: Other means of transportation that don\u2019t involve the road, such as planes, trains and ships.<\/li>\nCommercial and domestic fuel<\/em>: Heating and powering of indoor spaces like our homes, offices and shops by combustion of fuels such as gas, oil and wood.<\/li>\nIndustrial and construction<\/em>: Waste management activities like energy from waste plants and \u2018Non-Road Mobile Machinery,\u2019 i.e., construction sites and machines like diggers, excavators and diesel generators.<\/li>\nMiscellaneous<\/em>: Other smaller sources like sewage treatment and smaller household sources<\/li>\nBackground<\/em>: Pollution produced outside of London that has been blown in by the wind.<\/li>\n<\/ol>\nPollution health impacts<\/strong><\/p>\nThe map displays two pollutants: NOx<\/sub> and PM2.5<\/sub>. NOx<\/sub> are a sum of nitric oxide (NO) and nitrogen dioxide (NO2<\/sub>) which, along with PM2.5<\/sub>, are the main air pollutants of concern in London. They are harmful to human health and are associated with adverse health outcomes like asthma, strokes and cancer.<\/p>\nLondon also has emissions inventories for NOx<\/sub> and PM2.5<\/sub>, meaning there is a detailed list of all the activities contributing to these pollutants across the city. The model that is behind the dataset requires these emission inventories.<\/p>\nThis is the first time that modelled pollution sources data has been displayed in this detail across Greater London on an interactive public map. With a better understanding of which activities are causing pollution and where, leaders and communities can develop targeted solutions that clean the air and protect people\u2019s health.<\/p>\n
