What are we doing to improve?• Leading UK industry investment in
alternative fuels • Offering quality controlled, factory
blended cements
• Alternative (non primary) raw materials
• Alternative transport (rail)
• More efficient logistics fleet investment
• ‘Safe and efficient’ driver training
• Energy reduction programmes and investments
• EPOD paperless and efficient delivery system
CEMEX UK
• has invested around £35m on equipment, trials and
securing permits for alternative fuel use and
environmental improvements since 2006
• is saving over 200,000 tonnes CO2 in 2013 compared to
traditional fossil fuels
• has used enough climafuel to reduce landfill by 275,000
tonnes in 2012
• has reduced CO2 per tonne cement by 10% over recent
years
Using tyres saves adding iron-oxide to cement. Each year 40 million
tyres are scrapped in the UK.
Climafuel is non recyclable household waste that has
been sorted and dried, ~60% biomass.
Secondary Liquid Fuel (SLF) is made from
industrial liquid wastes that can’t be recycled.
Waste derived fuels achievements
Our cement business uses nearly 200 times more waste and by products than it sends to landfill!
• Significant progress since 2005 on all alternative fuels – 62% in 2013
• UK Industry average est 40.5% (2013)
• Climafuel is a particular success story and has contributed significantly towards our 10% reduction in CO2
• NOx and SOx emissions also reduced – high temperatures (1400oC) and long residence time
• Reduced fossil fuel consumption and landfill
Waste derived fuels achievements
Ultimate target to get to 100%; but working towards 80% in coming years

CEMEX UK
UK Industry average
ISO14001, responsible sourcing and Carbon Trust Standard
• These are important certifications:
• deliver confidence in us as a supplier
• improve our own performance
• meet client needs in the sustainable marketplace
• All CEMEX cements in the UK are certified to ISO14001, BES6001 responsible sourcing standard to ‘Very Good’ and the Carbon Trust Standard
• Both ISO14001 and BES6001 can allow greater credits under various green building and infrastructure works
• The Carbon Trust Standard commits us to reducing CO2 over consecutive 3 year periods
Summary and the future
• The sustainability and climate change agenda is a key issue for us
• We are committed to continuing to play our part and innovating
• Our actions to reduce CO2 have only just started• Our products and partnerships will contribute towards a
more sustainable, lower carbon and more climate resilient built environment
The future:• Major steps in alternative fuel use and associated reduced
CO2 - signed up to ‘MPA Cement 2050 Roadmap’• Reduced waste generation, water and energy use• Increased partnership working to find whole supply chain
solutions• Decarbonising roadmaps working across all business areas
and sector associations• Innovations such as Carbon Capture & Storage technology
will advance and may become viable
