Trasporti ed energia: strategie di pianificazione in ambito urbano

Abstract

The fight against climate changing pushed the States of the EuropeanUnion to adopt new, strong and efficient objectives to protect theenvironment and improve life condition in urban centers.Particular attention is paid to the reduction of CO2 emissions in orderto promote a more livable environment and sustainable urbandevelopment. This growing communitarian policy and vision representsa suitable context for the introduction of innovative urban planningand managing practices allowing an attentive exploitation of naturalresources.The principle of sustainable and durable development and the newconcept of “energy planning” take to a revision of existent tools(PRG-Piano Regolatore Generale, PUM-Piano Urbano della Mobilità,etc.) used by Italian Public Administrations to plan and manage urbanspaces and to the introduction of new ones (PEC-Piano EnergeticoComunale, etc.).From this modern point of view, the field of transport and mobilitycovers a strategic role for two main reasons. The first is the relevantcontribution of transports to the production of CO2 emissions(transports are responsible of the 30 - 40% of CO2 emissions in urbancenters) and other toxic matters (PM10, NOx etc.); the second one isthe strong impact that the effectiveness of public transports can haveon citizens’ quality of life and the reduction of private cars’ use.Taking into account the wide range of fields, activities and serviceswhose efficiency and sustainability depends on that one of the urbanmobility system, a great number of actions can be proposed.The effective problem is the complexity of their mutual interaction inorder to satisfy urban exigencies and respect existing regulatoryindications.The analysis of alternative actions, technologies and scenarios thatLocal Administration can suppose to apply and/or realize might resultvery interesting taking into consideration also the recentcommunitarian policy of “20-20-20” aiming to reach a reduction of20% in greenhouse gas emissions, energy consumption to comefrom renewable resources and primary energy use.It turns out to be necessary a revision of existing management andplanning tools in the field of mobility and the engagement of newmethodologies (monitoring indicators, campaign for citizens’involvement, dynamic and temporal use of infrastructures, etc.) andtechnologies (biofuels, electric vehicles, etc.) to support LocalAdministration during a transitional moment in which long and shorttermdevelopment plans are strongly questioned.The more interesting strategic tool recently introduced into LA landplanning practices is the “Action Plan”.Starting from the identification of environmental, social and economicalweaknesses and treats of the urban system the “Action Plan” tries toindividuate critical situations and propose, as a kind of agenda, timesand modalities of LA actions.Being strongly involved in these items, the city of Genoa turns to bea meaningful case study.
