Bentley has said it is "on course" to become the world’s most sustainable luxury car brand.
The manufacturer said the latest data recorded at its Crewe headquarters shows an "impressive overall reduction" in environmental impact per vehicle when comparing 2021 data against 2020 figures.
It added that it achieved the fall even though it increased production volume by 38.3% in the same period.

Bentley said that the latest reduction contributes to an overall reduction of 76.7% per vehicle since 2010.
The amount of water used at the factory was cut by 26.6% in 2021, thanks mainly to major investment in water capture measures and installing water recycling systems.
It added that some of this decrease was also due to a reduction in 'domestic' water usage onsite, caused by a greater proportion of employees working from home during the pandemic.
However, a second water capture tank – with the capacity to provide a further 1,800-litres of rainwater per day - has just been installed on the roof of the new Excellence Centre for Vehicle Finish. The new tank will also be attached to the reverse osmosis water system in the paint shop and will directly serve toilet facilities in the new manufacturing finishing area.
The new data also shows a drop of 70.2% in CO2 emissions at the Pyms Lane site, where all Bentley models are built.
Bentley said the fall is largely due to its use of green gas and biofuels in onsite logistic vehicles.
The figures further improve on past CO2 cuts at the factory, thanks to the use of energy generated from the company’s extensive onsite solar PV system. In January, Bentley confirmed that the system, which currently consists of circa 31,500 panels will be extended further.
The company added that energy consumption per vehicle was down 17.2% because of "an ongoing focus on efficiency, the use of green gas and the impact of a more efficient boiler system".
Peter Bosch, member of the board for manufacturing, said: "The focus of our Beyond100 strategy is to ensure Bentley is a world leader in the delivery of sustainable luxury mobility.
"These latest encouraging figures show that the continuous focus of our manufacturing strategy on reducing waste, water and energy use are paying dividends by delivering impactful year on year change.
"Our site is already carbon neutral and the ethos behind our Dream Factory concept is to go-to-zero in terms of environmental impact.
"We are planning more solar panels and investment in VOCs mitigation will take place in 2022, to make Crewe the most sustainable site that it can possible be.
"Longer term, the £2.5bn investment we announced in January 2022 will help us further transform our facilities, combining our unique fusion of craftsmanship, customer interaction and colleague experience to build the platform for our first Bentley BEV."
