Posti was among the first to join the new energy efficiency agreement period 2017–2025. The agreement is a voluntary commitment to improve energy efficiency. Posti signed the agreement for the second time.
Posti aims to reduce the energy consumption of its facilities by 10.5 percent during the review period 2014–2025. The relevant measures concern the properties with the highest rates of energy consumption. In 2017, Posti continued to replace lighting technology and implement changes to lighting control. Lighting is responsible for nearly 60 percent of the energy consumption in Posti’s facilities. The electricity consumption reduction target of three percent was exceeded but, for heating energy, the achieved reduction of two percent fell short of the target of three percent.
Three new electric car charging stations were built at Posti’s head office in late 2017. The charging stations can be used to charge six vehicles at a time.
Reducing energy consumption by solar energy and lighting solutions
Posti uses electricity produced from renewable energy sources at all of its Finnish properties. In late 2016, Posti mounted 1,920 solar panels on the roof of the logistics center in Vantaa. The nominal power of the plant is 500 kW. Its calculated annual output is 450,000 kW. This is equal to the annual consumption of approximately 25 detached houses. Posti uses all of the energy itself, because the logistics center operates around the clock.
The Vantaa logistics center’s investments in LED lighting and the solar power plant have already produced substantial savings. In July 2017, for example, the combination of solar power and new lighting solutions led to a reduction of 35 percent in consumption compared to July of the previous year. The annual savings effect is 20 percent.
The annual output of the solar power plant was slightly lower than its calculated output due to the summer being cooler than average. The number of sunny days was lower than usual.
Significant transport cost benefits through the improvement of utilization rates
The environmental efficiency of transport operations is improved primarily by planning routes efficiently, ensuring a high utilization rate, combining deliveries, and driving in an environmentally responsible manner.
Posti currently uses the same vehicles for transporting printed mail items, parcels and freight. The fleet is renewed continuously to respond to changing needs. The utilization rates of vehicles have continued to improve considerably due to route optimization and the combining of transports. Maintaining a high fleet utilization rate is part of the day-to-day management of production operations.
The improved utilization rate has brought cost benefits through lower vehicle costs and the vehicles’ reduced fuel and servicing costs. The average fuel consumption of delivery vehicles turned to a decrease in 2017.
The vehicles’ loading rates, volumes and the weights of the transported loads have increased. These have a direct impact on fuel consumption.
Green Office system engages the personnel in day-to-day environmental awareness
Posti’s head office has been part of the WWF Green Office environmental program since 2014. Green Office is a practical environmental management system for offices. It helps workplaces reduce their environmental impacts, achieve savings in energy and material consumption as well as mitigate climate change. The program aims to reduce the ecological footprint and greenhouse gases. Even small acts are significant when there are many people involved. In 2016, the greenhouse gas emissions of offices were reduced by a total of 4,400 tons compared to the previous year. In total, the offices participating in the Green Office initiative have achieved savings of some 55,300 tons in greenhouse gas emissions in 2007–2016.
