Overview

Evaluates the environmental impact of coal-based district heating systems, highlighting the need for alternative low-carbon solutions.

Key Points

  • The aim is to provide a more accurate life cycle assessment of coal-fired district heating systems using a marginal perspective.
  • Introduced a new allocation method based on marginal perspectives for life cycle assessment
  • Analyzed health damage and greenhouse gas emissions from district heating systems
  • Compared the environmental impact against other heating alternatives like natural gas and heat pumps
  • Health damage from district heating is 3.17 × 10 −7 DALYs/kWh
  • Greenhouse gas emissions are calculated at 276 g CO2 eq/kWh
  • Conventional methods overestimate environmental impacts by over 80%
  • Coal-based district heating retains advantages over some alternatives based on current technology
  • Transition to heat pumps is not yet feasible due to existing conditions.
