We have committed to decreasing our Scope 1 and 2 emissions, that is emissions from our own operations, by 41% by 2030, compared to the 2014 baseline. This is one of our 2 long-term targets accepted by the Science Based Target Initiative. We report on progress annually.
Reducing our own energy use. Although the carbon footprint of our own facilities constitutes only a small part of our total footprint, we still wherever possible aim to minimize the energy use, waste and water use in our own facilities.
In 2018, we decreased our electricity consumption across our facilities by 3% compared to 2017 and at the same time 27% of our total purchased electricity was from renewable sources. All our real estate regions contributed to an overall energy saving of 68 000 MWh. We ran several projects during 2018 around the world, including new chillers in India and China, and boilers in the UK and France, as well as building envelope upgrades in Finland and France. We installed solar panels in our Portugal site . We continued to install LED lighting across our portfolio and introduced Heating, Ventilation and Air Conditioning (HVAC) controls in various facilities. Where possible we aim to apply a variety of methods to reduce our energy use. Finally we also introduced a global environmental data collection and reporting tool which together with the new Waste Management Guidelines has seen an increase in the number of sites reporting their utility data.
Reducing water use and waste. 2018 was the first year in which we introduced a water program within our supply chain. Our own facilities do not use a significant amount of water, mostly for sanitary purposes. Even so we minimize water use even in our own facilities wherever possible. We have identified supplier categories where water may be a material risk and initially addressed them through a water assessment program.
150 of our top manufacturing suppliers representing around 19% of total spend (or manufacturing spend), participated in water assessment via CDP Water assessment program. Out of participating suppliers, 63% (94) had undertaken a water-related risk assessment for their direct operations and 41% have identified actual water-related risks in their operations such as increased water stress, flooding and higher water prices. 23% (34) of the responding suppliers also engaged with their own supply chain on water risk, and a further 9% are planning to do so in the upcoming two years. In comparison with our direct suppliers, who saw water stress, flooding and prices as core risks, tier 2 suppliers see also drought and increased water scarcity as issues. 55% (88) of the suppliers have a company-wide water policy, including elements such as commitment beyond regulatory compliance, commitment to water stewardship and collective action, description of business impact on water and description of water-related performance standards for direct operations as well as company water targets and goals.
68% (102) of the suppliers reported water consumption information and 91 water discharge information. 54% (81) of the suppliers reported a structured target or goal. A structured target is considered to be one with a defined level (e.g. company-wide or basin), any quantified metric (e.g. % reduction in total water consumption), and an end year.
Encouraging employee commuting in Finland. Helsinki Region Transport (HSL) chose Nokia as the winner of the 2018 Commuting Forerunner award as we actively encourage our employees to walk, cycle, use public transport and carpool.
The Commuting Forerunner Award is given to an employer in Finland who strongly drives for sustainable commuting and business travel while at the same time increasing and supporting wellbeing. We have a long list of activities through which we have encouraged our employees to move wisely during the last two years.
The company has supported change for example by encouraging employees in Finland to buy a monthly public transportation ticket by crediting an amount per year to employees. Our teams have participated in the cyclists' race in Finland and our campuses have also offered bicycle maintenance for our employees at a special price. The actions are not only limited to just the head office campus in Espoo, but cycling has also been promoted at our offices in Oulu and Tampere. We have increased the number of electric car charging stations, and employees can search for available charging stations with a dedicated app.
As part of our leasing car policy, the lower the CO2 emissions of the car, the smaller the employee's leasing contribution. This has increased the share of hybrid and electric cars.
Our employees in Espoo, Finland took part in the Vedia Ride Pilot, where they can look for carpooling mates through an app. The company has also been actively discussing with HSL to influence bus-routes in the western parts of Espoo so that our employees in in the campus would find it easy to make their journeys by public transport.
Employees have been proactive. Many of these commuting and mobility initiatives have actually risen from the ideas of our active employees, which the company has then started to support. We all also recognize the health benefits of walking and cycling more. We will continue to investigate and encourage new ways of encouraging eco-friendly commuting.
