Different pieces of the puzzleManagement tools Sustainability program SRS, targets: By 2030, SRS will be fossil fuel free By 2020, CO2 emissions < 1.5 t/person SRS will be adapted to future climate change Requirements on developers Monitoring and evaluation process CCI road-mapIncentives Stakeholder involvement Capacity-building program Good-will
Experiences:Road-map - scenarios for decision making• As an assessment method • Adopting emission reduction targets • Preparing actions plans • Implementing measures • Monitoring and verifying results (long term)• A tool for prioritisation of actions • The initial prioritisation may change over time as the calculated impact of one action may change• Focus on climate • Missing other urban/regional (benefits) challenges: sustainability much more than just climate issue
Experiences• Difficult to assess and measure the impact of transport-related requirements • transport systems are complex. • added impact of two or more actions are difficult to assess even if the impact of one actions may be known. • A sustainable transport system relies on individual choices – how to predict behavioural change? • Will require a good set-up of “carrots and sticks”
Experiences • The future is difficult to predict • Future energy mix depends more on fuel costs than environmental impact • Future car fleet – depends more on vehicle and fuel costs than environmental impacts we depend on strong political intervention to reach our targets • Credits – no useful tool • CCI System Boundary • Difficult to reach climate neutrality within a given geographical boundary • Missing effects of embedded materials • Missing the main problem – consumption
Challenges• Involvement of key stakeholders and policy-makers• Overcoming the barrier of long-term thinking and decision-making• Assessment of behavioral change• The transport sector• Reflection of other urban benefits• Improving the link between scenario development and robuststrategies• How best to communicate results to the general public?

Baseline Energy• Energy use in buildings: max 80 kWh/m2 (including heating, cooling, hot water, building electricity)• Use of energy efficient appliances & systems (household appliances, lighting, elevators, ventilation systems, etc)• District heating and district cooling• Electricity - Nordic energy mix• Eco-labelled electricity used in all amenitiesSwedish preconditions Efficient energy-utilities for district heating and cooling Very low fossil content in the Nordic electricity-mix A very good understanding of energy efficiency among the general public since the 70-ties
Strategies: EnergyNon-area specific changes in the systems• Bio-fuels in district heating – lower CHG emissions• Increased renewable electricity – lower CHG emissionsArea specific requirements – Scenario 1• Energy efficient buildings: 55 kWh/m2 (heating, cooling, hot water, building electricity)• Local energy production • 2 kWh/m2 Solar PVs or • 6 kWh/m2 heat exchanger• 100 % eco-labelled electricity for all technical installations in buildings• Reduced energy use in water and wastewater distribution• Biogas production – from sewage and food waste (wastegrinder to sewer)
Strategies: EnergyArea specific requirements – Scenario 2• Energy efficient buildings: 45 kWh/m2 (heating, cooling, hot water, building electricity)• Local energy production Solar PVs or heat-exchange ??• Increased biogas production • food waste (separate collection) • organic waste from cruise ships (separate collection)• 100 % eco-labelled household- and operational electricity
Baseline: Transport Fairly good public transport in the area (subway and buss) Fairly good infrastructure for pedestrians/cyclists Parking for bicycles, residential: 1-2 parking/unit Car-pools in the area with well-situated designated parking Inner city location => high percentage using public transport (approx. 50% commuting to work)
Strategies: TransportNon-area specific changes in the systems• Natural changes in the vehicle fleet• ???Area specific requirements – Scenario 1• Reversed traffic hierarchy (physical planning, enabling)• ICT for behavioural change (planning tools, information systems, etc)• Limited access to parking• Car pools• Consolidation centre for goodsArea specific requirements – Scenario 2• Implementation of traffic hierarchy through legislative measures• Area specific restriction on vehicles (electrical vehicles for distribution, etc)• Mobility management (congestion fees, smart box, proactive advisory service, etc)
Baseline: Waste (solid + liquid)Solid Waste• Residential: Vacuum waste collection system (3 fractions), separate recycling room for remaining waste, e.g. electronics, glass, bulk waste• Commercial: actors manage their own waste• Organic waste mixed with combustible waste• Waste generation about 10% lower than Stockholm average• Very high volumes to recycling• 0% to landfill• Recycling of packaging (not materials)Water / wastewaterWater and wastewater system in Stockholm is already CO2-positive!• Water use: 150 l/person (residential) 45 l/person (offices and retail)• Centralised wastewater treatment (99% BOD and P-removal and >50% N- removal)• Biogas generation from sludge (sludge used to cover mining landfill)• Leakage into sewers estimated to 10% (Stockholm average 40%)• Losses from water mains estimated to 10% (Stockholm average 25%)
Strategies: WasteNon-area specific changes in the systems• Vacuum systems are required in all new developmentsArea specific requirements – Scenario 1• Local vacuum operated waste collection system with increased no of fractions => increased material recovery• Food waste from homes and workplaces is collected (through churns)• Gardening waste is recycled locally• Local Reuse Center – decrease in residential bulk waste• Lower waste generation in total (conscious consumption, lighter materials).• Water use: 100 l/person (residential) 30 l/person (offices and retail)Area specific requirements – Scenario 2• Reduce waste generation in total (more IT - less paper, shifting packaging materials, etc• Material recovery• Reuse nutrients from organic waste and water closets
Strategies: WastePhase 2Solid waste• Source separation of organic waste from residential and commercial areas for biogas production (a potential risk: minimising waste => reduced biogas production)• Active incentive system to avoid waste generation and promote reuse instead of recycling (computers, furniture, appliances, etc.)• Water fountains in public areas, offices, etc to reduce use of water bottles• Collection of aluminium packaging and products (excl cans)• Replace locally distributed printed material with digital media• Organic waste from public open space used as mulch to avoid compostingWater and Wastewater• Source-separation of nutrients at toilet (vacuum system) and recycling of nutrients to replace commercial fertilisers• Collecting organic waste and black-water from ships to produce biogas and replace commercial fertilisers (A-credit)• Stormwater management
