How the change works
- 01 / Public decision
Warmth and standard
- 02 / Physical change
Less emissive technologies
- 03 / Possible outcome
Reduced exposure
Ensuring heat is a need; choosing how to produce it determines exposure to pollution.
Research and local documents ↓What the evidence tells us
Studies on the Huai River exploit a geographical discontinuity in heating policy to assess prolonged exposure to particulate matter.
Putting the choices into practice
Service
The challengeHeat linked to coal
The responseSuitable technologies
Indicator
The challengeConfused pollutants
The responseClearly defined particle fractions
Objective
The challengeReduce comfort
The responseHeat with less emissions
The diagram compares choices and conditions for putting them into practice. Measured outcomes and their limits are discussed in the evidence.
Research and local documents ↓Conditions and limits
The quasi-experimental design has a precise perimeter. Total particulate matter and PM10 are not the same measure. Leaving homes in the cold is not the solution.
Other possible benefits
Comfort and health considered together.
