Scope

Purpose

This assessments purpose is to evaluate greenhouse gas emissions and cost which are caused by small-scale energy production in Helsinki Metropolitan Area. Small-scale energy production means other used heating methods than district heating and those district heating units, which thermal energy output is less than 50 MW, in this assessment.

Boundaries

  • Spatial: Helsinki Metropolitan Area (Helsinki, Espoo, Vantaa, Kauniainen).
  • Emissions: CO2, PM2.5.
  • Heating methods:
    • District heating
    • The others
  • Fuels: All (H/L oil, Pellet, Chip, Gas, Coal).
  • Other impacts: Costs
    • directly from the activity itself of the greenhouse trade
    • new district heating extension costs

Scenarios

Base-case:

  • Current district heating status in Helsinki Metropolitan Area
    • emissions
    • fuels used in plants
    • city's need for heat
    • costs

Future scenarios:

  • Changes in district heating network:
    • expansion?
    • costs, especially what does emission trading affect on costs
    • new plants

Intented users

  • Local district heating distributors in Helsinki Metropolitan Area
  • Participants of the | World Wide Views on Global Warming stakeholder meetings
  • Participants of the COP-15 meeting in Copenhagen
  • City-level policy-makers in all sectors in Helsinki Metropolitan Area as well as everywhere else
  • International policy-makers related to climate change
  • General public
  • Scientists working on climate change and related fields of study

Participants

  • The Assessment and Modeling unit, National Institute for Health and Welfare of Finland, THL.
    • Jouni Tuomisto (leading researcher, person in chrage)
    • Pasi Sorsa (assisting researcher, executing the assessment)
  • Funded by Bioher-project

Definition

GABI software model parameters: File:Parameters, gabi-model.xls.

Decision variables

  • Decisions:
    • International: Options of the international greenhouse gas trade mechanisms

Indicator variables

Analyses

  • Analyses for small scale district heating plants and other used heating methods in Helsinki Metropolitan Area
    • fine particles PM2.5 and CO2 emissions
    • costs
