Almada, 28 May 2009 Urban benchmark and actions for sustainability Lorenzo Bono 3
Urban Ecosystem Europe The report has been worked out by Ambiente Italia Research Institute and financed by DEXIA Group. The survey is endorsed by the NGO Legambiente-Italy and by EU city networks such as ICLEI, UBC, MEDCITIES, CLIMATE ALLIANCE, the French Comité 21, the Italian Coordinamento Agende 21 Locali and ANCI. 4
Urban Ecosystem Europe The Urban Ecosystem Europe Report provides an integrated assessment (25 indicators) of 32 main or bigger cities in Europe and focuses on their local responses capacity and needs. The report shows strengths and weaknesses and provides a baseline review clearly addressed to the environmental sustainability dimension, with climate change as core issue. 5
A tool coherent with EU policies engagements The 2006 EU - Thematic strategy on the urban environment says that To monitor and up-date the effectiveness of the Strategy, accessible urban data is needed and the EU Parlament (2006) demands common core indicators to allow for comparisons and benchmarking between European cities The 2004-07 Aalborg commitments engage signatories to cooperate with the European Sustainable Cities & Towns Campaign and its networks to monitor and evaluate progress towards meeting sustainability targets. The 2007 EU Leipzig Chart for Sustainable Cities says that Indicators and Benchmaking should become a relevant tool to drive European, national and local policies. 6
25 indicators, 6 themes Local action for health - Natural common goods Responsible consumption and lifestyle Planning better mobility, less traffic Energy and Climate change Vibrant, sustainable local economy and social equity, justice and coesion Local Management towards sustainability and Governance 7

How is critical the situation? Are there positive reactions? European citizens are exposed to relevant health risks, due to air pollution. The situation is still over the limit. Car users are invading cities, but local policies could succeed. Municipal waste are a waste of energy and materials, but local policies and life styles make the difference. Risks due to climate changes could be avoided also thanks to local administrations, but now it s time to act. 11
Energy: local policies A good majority (21) of the 32 cities adopted local CO2 reduction targets Barcelona, Hannover, Munchen, Oslo, Zaragoza and Praha defined very innovative local regulations to improve energy efficiency in buildings In Helsinki, Kobenhavn, Aarhus, Tampere and Stockholm more than 70% of the population is connected to a district heating system. In Oslo all the traffic lights use LED tecnology, 60% in Lyon and 40% in Goteborg Heidelberg administration buy 25% of certified renewable energy for its electric consumptions 12
CO 2 target setting Munich: self commitment to a 10 % reduction every 5 years, since 2005. Copenhagen: - 20 % in the period 1990-2005 and goal of 20 % reduction by 2015 (2005 base). Amsterdam: the strategy New Climate for Amsterdam defines the target -40% by 2025 (1990 base); 30% of the consumed energy must be generated from local renewable energy sources (sun, wind and biomass) by 2025. Oslo: -50% by the year 2030 (1990 base). In January 2008, the City Council adopted a Ten point plan for reducing climate gas emissions. 13
CO 2 target setting Hamburg: Strategy for Climate Protection: -20% by 2020 (1990 base), but there is a self commitment which aims to reduce CO 2 emissions by 40 % until 2020 and by 80% until 2050. Stockholm: -25% per capita CO 2 emissions, from 5.3 tons (1990) to 4.0 tons (2005). The long-term target is to continue at the same rate: in theory, this means to become a fossil fuel free city by 2050. 14

Energy: public buildings Solar panels diffusion in public buildings is growing: Wien is the best for thermal panels (about 13.000 m 2 ). Good also Barcelona (4.300 m 2 ) and Lyon (3.500 m 2 ). Munchen has the greatest amount of photovoltaic panels on public buildings (more then 4.000 kw), followed at a certain distance by Barcelona and Roma. Heidelberg - as the first - and then Hannover, Helsinki and Dresda are the best among smaller sized cities. In Hannover and Copenhagen the first energy audits and retrofitting measures were done more than 10 years ago. Helsinki implemented energy audit in 80% of public buildings. 17
Energy: public buildings Copenhagen (2002-2006): electricity consumption -5 %, heating -7 %. Hamburg (2000-2007): energy consumption (electricity+heating) 10%. Stockholm: aim to reduce the energy consumption in the city s own buildings and plants by 10% by 2010 (compared to 2006). Oslo: all new municipal buildings will be of passive/low energy standard. Heating oil will be phased out by the end of 2011 and fossil energy for heating will be phased out entirely by 2020. 18

Energy savings in transport Car is used up to 70% for home to work trips in Italian cities, that, together with the Belgians have the higher number of circulating cars: Rome reaches 70 cars every 100 inhabitants, double than Berlin, London and Paris. In Riga and Copenhagen car has a very marginal use (20 cars/100 inh). In Praha workers use public transport (58%) more then cars (27%). Wien, Goteborg, Helsinki, Hannover, Kobenhavn and Stockholm achieved the goal to mantain below 50% the use of car in home to work trips, thanks to the combined use of the bicycle in short medium trips and a qualified public transport related to longer trips. 20
Energy savings in transport Amsterdam: only 25% of all journeys under 5 km by private car; 61% by bike. Between 1994 and 1997, 29% of such journeys took place by car and 52% by bicycle. Copenhagen: 36 % of inhabitants use a bike to go to work or study and 98% live less than 350 m from a public transport service. Stockholm: the share of trips to the city centre taken by public transport increased from 57% to 64% during the last ten years. In the morning peak hour, the share increased from 72% to 77%. 21
