Lappeenranta was one of the 18 best cities in the international WWF Earth Hour City Challenge 2016, in which the candidate cities were assessed on the basis of their contributions to climate protection. 124 cities from 20 countries, that consider themselves to be pioneers in climate change mitigation, participated in the challenge. Lappeenranta was also one of the finalists in 2014.
The international jury was particularly impressed by Lappeenranta's efforts to make the city waste-free and carbon-neutral by 2050.
Organised for the sixth time, the Earth Hour City Challenge measures the cities' preparedness for reducing greenhouse gas emissions produced in energy production and traffic and through food choices. The international jury was particularly impressed by Lappeenranta's efforts to make the city waste-free and carbon-neutral by 2050.
One of the ways in which Lappeenranta has reduced its emissions is by increasing the percentage of energy produced from renewable sources to 78. The city has adopted renewable district heating featuring the use of biomass. In addition, significant investments have been made in solar power, which is generated more by resident in the Lappeenranta region than in any other city in Finland. We have the biggest inland wind farm, and the suburb of Joutseno uses hydrogen to produce district heating. The city's solid expertise in energy issues is supported by Lappeenranta University of Technology, where the search for new solutions to climate change mitigation continues.
