Other forms of pollution caused by the use phase
of vehicles include noise pollution and waste.
The improper disposal of EOL vehicles generates
7-8 million tons of waste globally every year.107 Soil
contamination from lead battery manufacturing
and recycling is of particular concern in many
developing African countries lacking adequate
infrastructure for proper disposal and treatment of
vehicles, which are often imported from regions like
the US and EU. As developed markets transition
away from ICE vehicles, care must be taken to
avoid burdening less developed markets with
their disposal.108
Many countries have implemented policies and
regulations that place controls on pollution levels
in the automotive sector. For manufacturing,
regulations are strongest in the EU, where the
Industrial Emissions Directive requires companies
to implement the best available techniques (BAT) to cut the use and impacts of hazardous chemicals.109
For downstream pollution, the US Environmental
Protection Agency strengthened standards on
air pollutant emissions for light- and medium-
duty vehicles in 2024,110 and the EU revised the
Ambient Air Quality Directive in 2024 to impose
stricter limits on pollutants.111 Countries have also
imposed regulations on automotive noise levels. For
example, China adopted new regulations in 2021,112
and in the EU there are also requirements for noise
labelling in dealerships.113
More still needs to be done, however. Both
regulators and automotive companies, in
partnership with other stakeholders, need to
continue to advance action to mitigate pollution
and its environmental and social impacts across
the value chain, and avoid the longer-term liability
of EOL vehicle waste.
The automotive sector relies heavily on water for
production. Indeed, 30 million m3 (cubic metres) of
water were used in vehicle manufacturing in the EU
in 2022,114 and the sector has a CDP Water Watch
impact rating of “very high” (the second highest
category).115 The midstream manufacturing of each
vehicle requires 5,000 litres of water,116 however, life
cycle analysis indicates that car production requires
400,000-450,000 litres of water (mainly for metals
sourcing and electrical component manufacturing),
which indicates that 99% of water is consumed
upstream.117 This total is equivalent to over 10 years
of household water supply for the average person
in Europe.118
Upstream, water is critical for mining operations
and energy, chemicals, fibre, rubber and tyre
production. It’s also essential for livestock farming for leather, and forest products for packaging.
Where operations lie in arid places, impacts can
be magnified locally. For example, the World
Resources Institute found that 16% of critical
mineral mines, deposits and districts are located in
highly water-stressed areas, and in these locations,
at least 40% of water supply is required to meet
existing demand each year.119
In automotive manufacturing operations, some
of the primary uses of water include machinery
and part cooling, paint shops,120 leak testing,
and pretreatment and cleaning of the body
shell. Similarly, impacts can be magnified where
operations lie in arid places. For example, in 2022,
23% of water used in Volvo Cars’ own operations
was drawn from areas with high or very high water
stress across Europe, North America and Asia.121 2.3 Water use
2.4 Land-use change and ecosystem disturbance
Across the value chain, from raw materials to EOL
vehicles, land-use change is primarily driven by
upstream input industry activities. In particular,
the production of high-impact commodities such
as metals, rubber and leather, pulp and paper for
packaging, and energy supply, can result in:
–Land clearance and ecosystem fragmentation
–Soil degradation, erosion and compaction, and
increasing flows of sediment into nearby rivers
–Increase in non-natural fires and landslides from
the use of heavy machinery and explosives –Disruption or diversion of surface water regimes
and groundwater systems
Impacts are highly material-specific and clearly
attributable to the automotive sector. For example:
–For metals, 8% of mining-related deforestation
is attributable to the motor vehicle sector
(the second largest contributor after the
construction sector).122
–Approximately 70% of natural rubber is used
to produce tyres.123 Meanwhile, 90% of global
rubber is produced in South-East Asia, where Car production
requires 400,000-
450,000 litres of
water (mainly for
metals sourcing
and electrical
component
manufacturing).
