A Continuously Variable Transmission (CVT) can provide better fuel economy by allowing
the engine to run at its most efficient revolutions per minute (RPM) for a range of vehicle
speeds. This technology is used in the Prius (1.5l).
Variable Valve Timing (VVT-i) is a technology developed by Toyota, which varies the
timing of the intake valves. Dual VVT-i adjusts both intake and exhaust camshafts.These
engines significantly reduce hydrocarbon emissions.
Meeting European Emissions Standards
European emission standards define the limits for exhaust emissions of new vehicles
sold in EU member states. Successive European directives progressively introduce
increasingly stringent standards. The stages are typically referred to as Euro 1, Euro 2,
Euro 3, Euro 4 and Euro 5 fuels for Light Duty Vehicle standards. Currently, emissions of
nitrogen oxide (NOx), hydrocarbons (HC), carbon monoxide (CO) and particulate matter
(PM) are regulated for most vehicle types. Toyota sales that meet the various stages are
reflected below.
Special Story
In 2007, the Weld Plant at the Prospecton site undertook a major energy saving drive,
under the theme of Environmental and Global Warming. Their aim within a two-year
period was to replace all the high-energy lights of 400W each with low energy
fluorescent tubes, and to ensure that unnecessary lights were not used. They achieved
this – along with a monthly energy saving in the weld plant of 7,455 kWh – within 18
months, through the removal, replacement or disabling of a total of 961 400-watt bulbs.

Budgeting and Planning
As part of our drive to integrate environmental considerations into everything we do,
no single “environmental budget” is compiled for our operations. Each department is
responsible for capital expenditure, operational expenditure and maintenance budgets
for environmental performance. Thus no consolidated figure can be reported for Toyota
South Africa.
