Abstract: Athens, a metropolis characterized by agglutination and compactness, but at the same time facing numerous urban and transport issues, saw its population swell during the 20th century which led to extensive urbanization phenomena. This continued urbanization increases profoundly all urban activities with transportation being the key driver in energy consumption. Theories for sustainable cities prerequisite are the integration of a number of acts in order to reduce energy consumption, with mobility being the first consideration among others. The aim of this paper is to critically explore implemented policies and plans as well as forthcoming strategic plans in terms of sustainable mobility as imposed in large scale regeneration plans in contemporary Athens. Research focuses on strategic interventions since the 1980s, such as the Athenian Daktylios (ring road for circulation management) and its later adjustments, the upcoming pedestrianization and unification of the commercial triangle and its subsequent tram line extension as well as the notable implementation of the metropolitan cycling network. Moreover, the discussion takes into consideration the implications of the Greek economic crisis in mobility choices, as aimless travels have been reduced to a minimum, several cars have been abandoned and cyclists seem to tentatively claim some space in the urban environment. What will likely be the next day in the Athenian historic centre? Considering the transformations that are expected in the immediate future, this research paper explores their potential to enhance urban environment, reduce climate change impacts and amplify resilience. Key words: Urbanization, Athens, economic crisis, sustainable mobility. 1. Introduction GHG (greenhouse gas) emissions. The Greek national climate change agenda, in Most of the world population lives in cities, which respect to sustainable mobility, is particularly are immensely affected by climate change. It is inadequate. Greece is the penultimate of the EU well-known that urban activities cause the vast countries in the assessment of policies dealing with majority of impacts in the environment, while also climate change, according to the Climate Change they tend to be one of the main receivers of these Performance Index 2014 [2]. National policies do not numerous impacts. Floods, sea level rising, urban heat “convince” citizens to alter their daily habits and yet island effect, extreme weather conditions, air and the shortage of provision in infrastructures and action noise pollution among others [1] are encountered daily plans is high.

Proposed solutions the last 5 years (2009-2013) has affected all factors of vary but, before we start using CDR (carbon dioxide the daily life and transportation could not remain removal) technologies, trying to capture and store CO2 intact.

During the last 15 years, there are a number of implemented measures and completed infrastructures 2.

The analysis focuses green buses, the development of Attiki Odos (the on the Athenian conurbation and examines sustainable mayor peri-urban highway) and many more. However, urban mobility strategies and their implementation mobility and accessibility issues had little attention during the last decade. A number of past and future and a few fragmented actions have been considered regeneration schemes are reported and assessed under towards integrated sustainable urban mobility strategic the scope of actual contribution on the sustainability plans. of the city.

It is also reported that there is an imbalance of such plans. Encouragingly though, 2012 was the year investing in underground means of transport (i.e., that the “strategic plan for transportation and metro) rather than on ground infrastructures (i.e., tram sustainable mobility in Athens” was firstly introduced and bus network), an evidence that indicates the as part of the Strategic plan of Athens, and in 2013, a indecisiveness of authorities to intervene in the actual bike sharing system in the Municipality of Athens was urban street level. Regarding cycling, progress is slow strongly debated. but steady with a number of municipalities acting pro Towards the implementation of such plans, there cycling however with numerous administration issues. are numerous needed transformations regarding the Athens Metropolitan Cycling Network, as planned by management of public transport, the development of the Sustainable Mobility Unit of NTUA (National an extended cycling network, the systematic upgrade Technical University of Athens) with the contribution of public spaces and the establishment of an integrated of the largest cycling group in Athens, has been pedestrian network, with the most important being the incorporated in the Strategic Plan of Athens 2021 and alteration
