Residential wood combustion (RWC) is a major source of air pollutants in the Nordic and many other countries. The emissions of the pollutants have been estimated with inventories on several scopes, e.g. local and national. An important aspect of the inventories is the spatial distribution of the emissions, as it has an effect on health impact assessments. In this study, we present a novel residential wood combustion emission inventory for the Nordic countries based on national inventories and new gridding of the emissions. We compare the emissions of the Nordic inventory, and especially their spatial distribution, to local assessments and European level TNO-newRWC-inventory to assess the spatial proxies used. Common proxies used in the national inventories in the Nordic countries were building data on locations and primary heating methods and questionnaire-based wood use estimates for appliances or primary heating methods. Chimney sweeper register data was identified as good proxy data, but such data may not be available in an applicable format. Comparisons of national inventories to local assessments showed the possibility to achieve similar spatial distributions through nation-wide methods as local ones. However, this won't guarantee that the emissions are similar. Comparison to the TNO-newRWC-inventory revealed the importance of how differences between urban and rural residential wood combustion are handled. The comparison also highlighted the importance of local characteristics of residential wood combustion in the spatial distribution of emissions.

在北欧和许多其他国家，住宅木材燃烧 (RWC) 是空气污染物的主要来源。污染物的排放量已通过多个范围（例如地方和国家）的清单进行估算。清单的一个重要方面是排放的空间分布，因为它对健康影响评估有影响。在这项研究中，我们根据国家清单和新的排放网格，为北欧国家提供了一种新型的住宅木材燃烧排放清单。我们将北欧清单的排放量，尤其是它们的空间分布，与当地评估和欧洲级别的 TNO-newRWC-inventory 进行比较，以评估所使用的空间代理。北欧国家国家清单中使用的通用替代物是建立关于地点和主要供暖方法的数据，以及基于问卷调查的器具或主要供暖方法的木材使用估算。烟囱清扫工登记数据被确定为良好的代理数据，但此类数据可能无法以适用的格式提供。国家清单与地方评估的比较表明，通过全国范围的方法实现与地方方法类似的空间分布的可能性。然而，这并不能保证排放量是相似的。与 TNO-newRWC-清单的比较揭示了如何处理城市和农村住宅木材燃烧之间差异的重要性。
