Urban benchmark and actions for sustainability
Almada, 28 May 2009

The report has been worked out by AmbienteItalia 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 CoordinamentoAgende 21 Locali and ANCI.

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 weaknessesand provides a baseline review clearly addressed to the environmental sustainabilitydimension, with climate change as core issue.

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 andbenchmarking 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 arelevant tool to drive European, national and local policies”.

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 energyand 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.
12
A good majority (21) of the 32 cities adopted local CO2 reduction targetsBarcelona, Hannover, Munchen, Oslo, Zaragoza and Praha defined very innovative local regulations to improve energy efficiency in buildingsIn 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 GoteborgHeidelberg administration buy 25% of certified renewable energy for its electric consumptions
Energy: local policies
13
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”.
CO2 target setting
14
Hamburg: Strategy for Climate Protection: -20% by 2020 (1990 base), but there is a self commitment which aims to reduce CO2 emissions by 40 % until 2020 and by 80% until 2050.
Stockholm: -25% per capita CO2 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.

Solar panels diffusion in public buildings is growing: Wien is the best for thermal panels(about 13.000 m2). Good also Barcelona (4.300 m2) and Lyon (3.500 m2). 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.
Energy: public buildings
18
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.

Energy savings in transportCar is used up to 70% for home to work trips in Italian cities, that, together with the Belgians havethe 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.
21
Energy savings in transport Amsterdam: only 25% of all journeys under 5 kmby 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%.
