Changes

Taking the two factors of accessibility and sustainability together, a '''major challenge''' for future transportation becomes clear: On One the one hand, future transportation has needs to meet the transportation demand for be faster and more accessible transportation for a growing number of people in an increasingly urban environment. On the other hand, the total amount of GHG emissions resulting from this transport have to be reduced.

*While the share of renewable energy varies largely throughout the Member States, it is overall still very low.

*At the moment, '''aviation''' is estimated to accounts account for 4.9% of man-made global warming. It is, however, the faster growing and at the same time the , yet least efficient mode of transport. <ref>European Federation for Transport and Environment AISBL. (2017). ''Aviation.''

(2017). ''Cities - key for Europe.'' Retrieved from https://eu-smartcities.eu/about/european_context</ref>. The GHG emissions from '''urban transport''' constitute a large share of GHG emissions and many cities reliable rely heavily on road transportation.

Identifying the main links between accessibility to transport, diversity and social mobility allows to understand the sociological aspect of the topic. The fact that mobility is connected to many fundamental aspects of an individual’s life, lays at the basis of these considerationsthis consideration. Generally, low access to transportation threatens to limit a person’s opportunities to '''access health care, education and jobs'''. It is therefore that mobility is such a relevant topic for society and that existing barriers to the access to transportation are so closely tied to '''social inequality'''. To a large extent, inequalities in the access to mobility stem from the varying '''user costs''' for different modes of transportation: Faster faster modes such as cars or trains are more often more expensive that than slower modes such a as walking or cycling. This is especially particularly the case for '''rural areas''', in which transportation infrastructure is often insufficient. There, individuals without private cars such as young, elderly or unemployed, are particularly vulnerable to the lack affordable mobility options<ref>The Telegraph. (2014). ''Rural communities more isolated as transport forgotten''. Retrieved from: http://www.telegraph.co.uk/news/uknews/road-and-rail-transport/10569800/Rural-communities-more-isolated-as-public-transport-forgotten.html</ref>. The problem is, however, also increasingly important for '''urban areas'''. According to experts, there is and has been an overemphasis of “higher speed” in urban planning, meaning that the transportation infrastructure would be mainly designed in a way to respond for a growing demand of faster transportation. Thereby, the aspect of “high density” seems to be neglected. In such an approach, there is a stronger focus on transportation responding to the growing travel demand as a tool to achieving social justice, ensuring that transport is affordable, easy to access for all parts of the society<ref>Litmann, T. (2017). ''Evaluating Accessibility for Transportation Planning''. Retrieved from http://www.vtpi.org/access.pdf</ref>.

Under Goal 11, ‘’Sustainable Cities and Communities’’ of the '''[[Sustainable Development Goals]]''', the UN agreed on a target to create "access to safe, affordable, accessible and sustainable transport systems for all, improving to improve road safety, notably by expanding public transport, with special attention to the needs of those in vulnerable situations, such as women, children, persons with disabilities and older elderly persons."<ref>United Nations Development Programme.

With regards to emissions, the '''2015 [[Paris Agreement]]''' laid down key international goals. It set the objectives to keeping the increase in global average temperature to well below 2°C above pre-industrial level and limit thus limiting the increase to 1.5°C. Moreover, the Agreement aims at reducing GHG emissions by at least 20% between 2012 and 2030. Expressing their commitment, the EU as well as most Member States individually ratified the Paris Agreement<ref>European Council. (2016). Climate Change: Council adopts decision for EU ratification of Paris Agreement Retrieved from http://www.consilium.europa.eu/en/press/press-releases/2016/10/04-adoption-paris-agreement/</ref>. On a European level, the '''EU 2020 strategy''', adopted in 2010, set general targets to address climate change and energy sustainability such as cutting GHG by 20% until 2020, compared to 1990 levels. As a follow upAdditionally, the '''2030 Energy Strategy''' targets aims to reduce emissions by 40% until 2030 compared to 1990 levels. Additionally, national emission targets are set by the [[Effort Sharing Decision]].

Looking more specifically at transport, the European Commission’s '''2011 White Paper''' constitutes outlines the EU’s main policy goals objectives for sustainability<ref>European Commission. (2017).
