TfL estimates that 600 of the fleet's 800 low-emission Euro VI buses (as defined by London Atmospheric Emissions Inventory, 2010) regularly pass through inner London boroughs.

Across the wider London area, these are complemented by around 300 New Routemasters with Euro V engines and 1,600 Euro III buses fitted with selective catalytic reduction equipment. These 1,900 vehicles have much lower oxides of nitrogen (NOx) than standard Euro V, IVs and IIIs, lifting them much closer to Euro VI levels. So, around 30 per cent of all buses are already at or close to the Euro VI standard for NOx compared with standard counterparts.

By 2020, the emission requirements for the Ultra Low Emission Zone, together with normal fleet replacement in the rest of London, will result in at least 5,300 buses meeting or exceeding the Euro VI engine standard. Additionally, there will be at least 300 zero-emission single-decks meaning that well over half the fleet will be at or above this standard, and operating in central London and neighbouring boroughs. The number of Euro VI buses (or better) will continue to increase into the next decade, contributing further to the downward trend in fleet emissions.
