Protecting the environment also means reducing the environmental impact of our own operations. Improving the efficiency of our own activities, such as the impacts from production, facilities, business travel, car fleet, and product transportation to market, helps us to save energy, cut carbon emissions and costs, and minimize waste. Our environmental management system helps us monitor progress and identify ways to improve further. It provides the basis for all of our environmental activity, focusing on environmental matters related to energy and material efficiency.
In 2016 we concentrated on a number of key areas in our own operations, areas such as, eco-efficient component sourcing, supply chain and subcontractor management. We looked at efficiency in our offices and laboratories in terms of energy consumption, freight transportation and packaging, waste and water usage, business travel, emissions from the leased car fleet. The fleet is used both by our services engineers for network site maintenance visits and by employees as benefit cars. With the acquisition of Alcatel-Lucent, Nokia now also has a marine fleet operated by Alcatel Submarine Networks (ASN), which is a part of Nokia, run as an independent business, and provides turnkey submarine network solutions.
In a year of integration of the former Alcatel-Lucent into Nokia, our total facility operations energy consumption stood at 1246 GWh. This decreased by approximately 9%, as compared to 2015, which, consequently, reflected a decrease of approximately 14% in our greenhouse gas emissions from facility operations. In comparison to 2015 figures, Nokia’s use of renewable electricity, as a combined entity, rose from 20% to 21%.
