Within the Nordic Region, road transport is responsible for just over 87% of transportation sector emissions, which has changed little since 1990 (see Box 2). When looking at total GHG emissions in the Nordic Region, 26% of total emissions are attributed to transportation and 23% to road transport specifically. This is a European-wide trend, with transport accounting for just under 30% of total emissions in the EU in 2022. One key method for reducing GHG emissions in the transportation sector in recent years has been to replace fossil fuel cars with electric-powered vehicles or alternative fuels. However, the European Environment Agency reports that “the improved energy efficiency of new vehicles and the increased use of biofuels … have been more than offset by the increase in demand for passenger transport and an increase in the share of passenger car transport,” which has “led to higher GHG emissions from passenger cars in 2019 compared to 2000.” As of 2022, the car accounted for around 80% of passenger kilometres travelled in each of the Nordic countries within the EU (Denmark, Sweden, and Finland). These figures are higher than the share for the EU-27 (73% of passenger-kilometres travelled in the EU are by car). And the total number of kilometres travelled by car in these countries has increased since 1995. While vehicle electrification can aid in decreasing transport emissions, the European Environment Agency is clear in its limitations:
Making cities more sustainable requires rethinking the built environment. The existing backbone of the living environment is often the street, specifically a street designed according to the dimensions of large motor vehicles. Research highlights the problems that electric vehicles pose to land use. One concern is the inevitable maintenance and potential expansion of impervious surfaces that come along with this space-occupying mode of transport associated with sprawling urban settlements. Fossil-fuel-free or electric vehicles both still require major public investments to build and maintain car infrastructure. Furthermore, road congestion remains the same, as do the negative health effects associated with sedentary lifestyles. Therefore, addressing road transport emissions and other holistic sustainability goals ultimately requires a transformation of the urban form, with sustainable urban mobility options—and particularly cycling—at the forefront. Cities and regions aiming to achieve sustainability must therefore consider how to reduce as many car trips as possible (even those made with electric cars) while maximizing the share of trips made by walking, cycling, and public transit.
Researchers at Chalmers University in Sweden recently conducted a study to evaluate the potential impact of substituting passenger car trips with e-bikes. Using the Västra Götaland county of Sweden (where Gothenburg sits) as a case study, the researchers ran a simulation study showing that, based on factors such as speed, trip duration, street gradients, and activities of trips, “e-bikes could replace 57.6% of car trips” in the county. Furthermore, they explored potential GHG emissions reductions in the area: “If the top 70% of feasible car users, ranked by shortest to longest daily travel distances, switch to e-bikes, emissions could be reduced by 10.1% compared to 2018 levels. If all feasible car users adopt e-bikes, a reduction of up to 22.8% in emissions could be achieved, representing the upper limit presented by our study.” The study provides encouraging findings for compact built environments where the researchers suggest that it is more possible for car trips to be replaced compared to sprawling environments.
