To ask the Scottish Government what assessment it has made of the effect that low-emission zones would have on greenhouse gas emissions.

< >The National Low Emission Framework process will almost certainly take account of greenhouse gas emissions and will be designed to incorporate an assessment of greenhouse gases. Low emission zones (LEZs) are designed primarily to reduce air quality emissions, such as nitrogen dioxide and particulate matter. Research has found that carbon dioxide emissions have not been reported to change significantly within LEZs, although black carbon benefits can be realized. For example, Glasgow City Council’s 2007 LEZ feasibility study identified no significant CO2 savings, whilst Milan have seen a positive impact on CO2 emissions where low or zero CO2 emission vehicles were promoted.
