Abstract
CO2 emissions reduction is a top element of transport policy agenda. Among other mitigation policy measures, eco-driving techniques have proven to be effective in reducing fuel consumption and CO2 emissions. The aim of this paper is to compare the impacts of adopting eco-driving in different cities, road segments, traffic, and driver features. It intends to gain an insight into how city size and driving characteristics can reduce fuel consumption and CO2 emissions in order to develop specific eco-driving strategies. Field trials were conducted in two Spanish cities (Madrid and Caceres). 24 drivers, with different driving experiences, drove two different vehicles (petrol and diesel) along roads with different characteristics. The experiment was divided into two periods of 2 weeks; after the first one, drivers received an eco-driving training course. The impacts of eco-driving were measured comparing before and after results. They showed that eco-driving is highly effective in reducing fuel consumption and CO2 emissions in both, large-congested and small, cities. Savings between 5% and 12% were achieved. The efficiency increases with road capacity and decreased with city size. Eco-driving appears to be more effective in small, uncongested cities. In addition, limiting speeds on high capacity roads has proven to be a good energy saving measure.
Highlights
One of the challenges in the developed world is to promote low-carbon mobility models in terms of social equity and fair distribution of wealth. is is, in short, the challenge sustainability poses
To advance in our missions and accelerate the implementation of the Paris Agreement, the 25th session of the Conference of Parties of the United Nations Framework Convention on Climate Change, COP25 took place in Madrid in 2019. At this Conference, 73 nations have committed to become carbon neutral by 2050 [4]. e agreement calls for an increase in the ambition of climate change commitments, following the timetable set out in the Paris Agreement, which aimed to reduce greenhouse gas (GHG) emissions by at least 40% by 2030 compared to 1990
E aim of this research is to compare eco-driving global effects by adopting this technique in two different cities as different as Madrid and Caceres. It intends to gain an insight into how city size and driving characteristics affect eco-driving. erefore, its goal is to compare general changes in fuel consumption, CO2 emissions, and driving patterns according to different types of city in order to develop specific eco-driving strategies
Summary
One of the challenges in the developed world is to promote low-carbon mobility models in terms of social equity and fair distribution of wealth. is is, in short, the challenge sustainability poses. Sustainable mobility means ensuring our transport systems respond to economic, social, and environmental needs, thereby minimizing any detrimental impact they have [1]. To advance in our missions and accelerate the implementation of the Paris Agreement, the 25th session of the Conference of Parties of the United Nations Framework Convention on Climate Change, COP25 took place in Madrid in 2019. At this Conference, 73 nations (including Spain) have committed to become carbon neutral by 2050 [4].
