Over 70% of our total environmental impact is in our supply chain. Quantifying the impact of our supply chain has transformed our corporate approach to reducing our environmental impact. We look to reduce our environmental impact where it is greatest; in our supply chain. This is embedded in “e:Mission”, our environmental sustainability plan to 2020. We have developed a corporate reduction target of 20% by 2020 for our supply chain impacts. We have embedded lifecycle thinking into our decision making for our infrastructure construction activities, innovating to produce low carbon solutions.
