In Finland, the small city of Lahti is setting an example for the world in achieving carbon neutrality. Located an hour north of Helsinki by train, Lahti is undertaking significant initiatives to reach this ambitious goal.
According to World Economic Forum,, the city, once known as a polluted industrial center, is making strides towards sustainability. Initially aiming for carbon neutrality by 2025, the city now expects to achieve this target a year or two later. Lahti has already reduced emissions by 64% below 1990 levels, with a goal of an 80% reduction and the remainder to be offset by programs like reforestation.
Lahti is implementing a multi-faceted approach to reduce carbon emissions. The city is expanding its network of bike lanes and public transportation, including the addition of electric buses and alternative fuel options. Lahti’s hockey team and symphony orchestra are also contributing to the effort by promoting sustainable transport among fans and audiences.
Innovative technology plays a key role in Lahti’s strategy. The city piloted a personal carbon trading app, rewarding residents for staying within a carbon budget. Another app challenges users to adopt eco-friendly habits. Moreover, Lahti is retrofitting city-owned buildings for energy efficiency and using waste heat from wastewater treatment for its district heating system.
Energy sources are also being reconsidered. Lahti ceased using coal in its main power plant and is now utilizing wood waste from forestry and gasification of non-recyclable trash for energy, though these solutions are seen as transitional.
The city boasts a remarkable recycling rate of 99% for household waste, with local companies finding innovative uses for waste materials, like converting oat hulls into xylitol. More than 113 different sustainability actions are being tracked, with progress made publicly available for citizen oversight.
Ojala highlights the citywide integration of these sustainability efforts, emphasizing the importance of community involvement and the challenges of changing transportation habits. Looking beyond climate neutrality, Lahti is contemplating a broader sustainability goal, focusing on reducing its ecological footprint and fostering nature positivity.
Lahti’s progress serves as a blueprint for other cities globally, illustrating the potential for urban centers to significantly contribute to combating climate change.
