6.1 Sustainable production processes Ever since 2008, we have been developing the Eco-Roca Project, which has two core goals: a 25% cut in CO 2 emissions by 2014, when compared with our 2006 emissions, and to manage waste-free industrial processes via our Zero Waste Programme. With regard to the first goal, reducing CO emissions, over the course of the period from 2006 to 2010, we have 2 managed, globally, to cut gas consumption by 14.9% and electricity consumption by 4.6%. This improvement means preventing the emission of 52,750 tonnes of CO into the atmosphere. Compared with 1990, in 2010 we 2 reduced our specific consumption of gas per unit of production by 60%. This figure is highly significant, as gas consumption represents approximately 90% of the greenhouse gas emissions arising from production processes. Turning to the second goal, the Zero Waste Programme to achieve industrial processes that produce no material waste, 75% of the plan has been complied with to date. 024
