Rolls-Royce Environmental Strategy
Maintain our drive to reduce the environmental impact of all our
business activities
Develop entirely new low-emission and renewable energy
products
Tidal stream, fuel cells, nuclear
Further reduce the environmental impact of our products; and
Rolls-Royce will apply its knowledge and technology to
developprofitable solutions to the challenge of climate change

External environmental reporting since 1999
The total amount of energy used by Rolls-Royce worldwide for
facility support and manufacturing operations (normalised by
revenue) has fallen by 38 per cent since 2006 exceeding the target
of 10 per cent.
The total greenhouse gas emissions associated with facility
support, manufacturing operations and product test continue to show
a downward trend. Emissions have decreased by 40 per cent since
2006 and by 59 per cent since 2003 (normalised by revenue).

To summarise
Rolls-Royce can help society develop an effective response to
climate change
Two thirds of the traditional R&D spend is addressing the
environment and energy efficiency
Leverage substantial technical advances and ongoing commitments
by Rolls-Royce in the development of environmentally friendly
technologiesLow-carbon opportunities extend beyond power
generation, with scope for re-use between sectors
Industry must remain competitive to be able to influence the
worldwide market in this field
