<strong>Antofagasta</strong> plc <strong>Sustainability</strong> <strong>Report</strong> 2011<br />

Environmental performance<br />

We are committed to managing our footprint and reducing<br />

our impacts wherever we can and we have developed an<br />

Environmental Management Programme to manage and<br />

measure our progress. The greatest potential environmental<br />

impacts from our operations are the transport of hazardous<br />

substances and the control of toxic waste. We have rigorous<br />

standards in place to ensure these are treated with great<br />

care. Other priorities include the efficient use of resources<br />

such as fuel, energy and water.<br />

We encourage workers and local people to care for the<br />

environment. For instance, as part of our ‘Care for Your Life,<br />

Care for Your Train’ programme and anti-litter campaign, we<br />

conducted three cleaning operations during 2011, removing<br />

200 tonnes of rubbish along a 9km stretch of track and<br />

provided anti-litter information to over 1,000 households.<br />

We manage our impact on the environment by:<br />

– Ensuring full compliance: We track our performance<br />

and compliance with regulation through regular internal<br />

and external audits in accordance with the OHSAS 18001<br />

standard. All our facilities are inspected each month and<br />

the Group’s Risk Management team conducts an annual<br />

assessment to ensure our standards continue to meet<br />

external legal requirements.<br />

– Mitigating impacts: Rail travel is among the most<br />

carbon-efficient means of transportation and we are<br />

working hard to further improve efficiency. Our electric<br />

and diesel locomotives account for 90% of our carbon<br />

emissions. To reduce fuel and electricity use, we ensure<br />

locomotive engines are turned off when not in use for<br />

more than 30 minutes and at the end of all journeys. We<br />

developed an exhaust colour chart and encourage<br />

engineers to regularly record the colour of exhaust fumes<br />

to enable better monitoring. In 2011, our total fuel<br />

consumption was 28.36 million litres, while our electricity<br />

consumption was just over 2,500,000 KWh. The figures<br />

are marginally higher than last year, but consistent with<br />

our historic average.
