Homework 1

What is shared understanding?

• All participants understand what decision options are considered, desired outcomes, objectives, facts, opinions and disagreements exist and why. Also why a certain decision option is selected.

• Everyone understands the whole picture without having to agree with each other.

What different purposes are there for participation in assessment and/or decision making?

• Openness builds trust among participants and outside observers.

• To make sure all relevant issues are raised and handled properly

• Through successful critique invalid statements can be ruled out from the assessment

What is benefit-risk assessment?

• Analyzing different scientific data to compare benefits and risks of an event, activity, food etc.

• For example assessing use of food additives: do the benefits outweigh possible risks?

Scope

Question

• What measures can be taken in Helsinki Metropolitan area to control climate change by reducing greenhouse gas emissions?

• How to reduce the per capita carbon dioxide emissions of the Helsinki Metropolitan Area by 39 per cent of the 1990 level by the year 2030?

Intended use and users

Helsinki Metropolitan area city authorities

Participants

• Cities of Helsinki, Espoo, Vantaa and Kauniainen

• A broad range of environmental protection, planning, traffic and public transport specialists from the cities

• YTV specialists in traffic, solid waste management and regional development

• representatives of energy companies

• interest groups

Boundaries

• Area: Helsinki Metropolitan area (Helsinki, Espoo, Vantaa and Kauniainen)

• Time: Based on years 1990, 2000 and 2004. Estimations made for year 2030.

• Considered sources of GHG emissions:

• Electric heating

• consumption electric power

• transport, district heating

• separate heating

• industry and machinery

• treatment of solid waste and waste water

Decisions and scenarios

Three considered scenarios

1. Business as usual

• Emission levels will stay roughly the same

• Emissions from transport increase, but new legislation improves e.g. energy efficiency

2. Reducing GHG emissions 39 % from the 1990 emission level

3. Continued rapid growth in electricity consumption

• If energy consuption grows according to forecasted trend, 5 % growth in GHG emissions by 2030 from the 2004 level

Timing

• The decision should be made as soon as possible to achieve best GHG emission reduction

Answer

Results

Trasportation

• Encourage use of public transport

• Improving competiveness of public transport

• National taxation policy towards choise of low-emission vehicles

Land use

• Location of dwellings, workplaces and services to decrease need for trasport

• growth of traffic and access to district heating

• Access to public transport

Electricity consumption

• Improving the awareness of resindents towards more efficient electricity consumption

• Cities should put a high value to energy efficiency of appliances

Heating of buildings

• Promoting district heating and cooling

• Correct use and maintanance of buildings

Procurement, consumption and waste

• Promoting material and energy efficiency and low emissions in city procurement

• Prevent solid waste formation

• Advice population how to avoid solid waste

• Enhancing material recycling

Energy generation and distribution

• Enhancing centralised cogeneration of electricity in Helsinki Metropolitan area

• Promoting eco-efficiency and renewable energy sources of decentralised energy generation

Conclusions

With the proposed improvements listed above it is possible to reach scenario 2: Reducing GHG emissions 39 % from the 1990 emission level.

The measures will be a drain on resources but doing nothing would be even more costly.

Rationale

Stakeholders

• Cities of Helsinki, Vantaa, Espoo and Kauniainen

• Citizens of Helsinki, Vantaa, Espoo and Kauniainen

• Enterprises e.g. energy producers, building companies, waste management

• Responsible city agencies e.g. environmental agencies, premises center, building supervision, Helsinki City Transport

• State government

• NGOs
