尽管全世界发表的关于生物炭的研究论文越来越多，但在一些国家，人们只是最近才注意到对生物炭的兴趣日益浓厚;波兰就是如此。我们分析了波兰的生物炭研究信息以及其他地方的经验教训，以确定与生物炭使用相关的重大机遇和风险。这些数据被输入到基于GIS的多标准分析中，以确定生物炭应用可以带来最大利益的领域。我们发现，波兰21.8%的农业用地至少有中度生物炭使用的迹象（土壤有机质低于2%，pH值低于5.5），而1.5%被列为优先，因为它也表现出污染。确定的潜在障碍包括生物质的可用性以及由于可能的国内和跨国生物质生产转移而导致的间接土地利用变化的相关风险。作为一项减缓气候变化战略，生物炭的使用可产生积极的全球影响，特别是在替代品有限的国家。推广一种因其共同效益而可行的缓解技术可能具有成本效益，这反过来又可以调整国家的观点，加强参与区域一级制定缓解政策。生物炭在温带条件下具有很大的前景，因此应开展进一步的研究，探讨生物炭的环境和社会经济影响。
Although increasing numbers of research papers regarding biochar are being published worldwide, in some countries growing interest in biochar has only recently been observed; this is true of Poland. We analysed information on biochar research in Poland alongside lessons learned elsewhere in order to identify the significant opportunities and risks associated with biochar use. This data fed into a GIS-based multicriteria analysis to identify areas where biochar application could deliver greatest benefit. We found that 21.8% of agricultural land in Poland has at least moderate indication for biochar use (soil organic matter below 2% and pH below 5.5), while 1.5% was categorized as a priority as it also exhibited contamination. Potential barriers identified included biomass availability and associated risks of indirect land-use change due to possible national and transnational biomass production displacement. Biochar use could have positive global consequences as a climate change mitigation strategy, particularly relevant in a country with limited alternatives. Scaling up a mitigation technology that is viable on account of its co-benefits might be cost-effective, which could, in turn, adjust national perspectives and stronger involvement in developing mitigation policies at the regional level. Biochar has much promise in temperate conditions and further research should therefore be assigned to explore biochar's environmental and socio-economic impacts.
