Climate impacts of forest bioenergy result from a multitude of warming and cooling effects and vary by location and technology. While past bioenergy studies have analysed a limited number of climate-altering pollutants and activities, no studies have jointly addressed supply chain greenhouse gas emissions, biogenic CO fluxes, aerosols and albedo changes at high spatial and process detail. Here, we present a national-level climate impact analysis of stationary bioenergy systems in Norway based on wood-burning stoves and wood biomass-based district heating. We find that cooling aerosols and albedo offset 60-70% of total warming, leaving a net warming of 340 or 69 kg COe MWh for stoves or district heating, respectively. Large variations are observed over locations for albedo, and over technology alternatives for aerosols. By demonstrating both notable magnitudes and complexities of different climate warming and cooling effects of forest bioenergy in Norway, our study emphasizes the need to consider multiple forcing agents in climate impact analysis of forest bioenergy.
森林生物能源对气候的影响源于多种升温与降温效应，且因地点和技术而异。虽然过去的生物能源研究分析了数量有限的改变气候的污染物和活动，但尚无研究在高空间和过程细节层面联合探讨供应链温室气体排放、生物源一氧化碳通量、气溶胶和反照率变化。在此，我们基于燃木炉灶和以木材生物质为基础的区域供热，对挪威的固定式生物能源系统进行了国家级气候影响分析。我们发现，冷却气溶胶和反照率抵消了总升温的60%-70%，燃木炉灶和区域供热的净升温分别为每兆瓦时340或69千克二氧化碳当量。反照率在不同地点差异很大，气溶胶在不同技术方案间差异也很大。通过展示挪威森林生物能源不同气候变暖和冷却效应的显著程度和复杂性，我们的研究强调在森林生物能源气候影响分析中需要考虑多种强迫因素。
