Temuco and Padre Las Casas, Chile, have severe problems of air pollution due to the extensive use of firewood for heating. The local authorities have made various efforts to improve fuel quality and introduce greater regulation into the market. Certified firewood guarantees low levels of humidity (< 25%) and has better combustion, but its distribution is still limited and the variables that determine its purchase have scarcely been studied. The aim of this study is to identify the determinants of certified firewood consumption in urban southern Chile. This study was conducted with a cross-sectional non-experimental design. Following a non-probability sampling by convenience, we applied 355 surveys to participants who use a firewood system. Nonparametric comparisons analyses were made to identify differences in the use of certified wood by socio demographic variables. In addition, an Ordinal Logistic Regression was used to analyze the relation between the use of certified firewood and various psycho-social variables. Half of the users of wood-burning stoves participating in the study declared that they “never” (38%) or “almost never” (12%) used certified firewood to heat their home. Situational and product-related variables, such as price, availability, convenience and time are fundamental to people’s purchase behavior, partially explaining the low public interest shown in this product. On the other hand, the results indicate the influence of socio-demographic variables such as income level and the presence of older adults at home, as well as psycho-social variables which include how much participants pay attention to air quality, the information level they have about it, the feelings of discomfort due to air pollution and concern for its effects on health. First, increasing information levels and awareness among the population through communication campaigns is necessary to promote the sustainable urban energy transition in southern Chile. Second, information strategies may be complemented by boosting employment, driving investment, improving income, and strengthening the mechanisms of social protection, especially for the most vulnerable groups, to be effective. Finally, protecting and stimulating the formal trade in firewood could increase the points of sale of certified firewood, which would facilitate user access to cleaner fuels.

谁购买经过认证的木柴？采用清洁燃料促进智利南部可持续能源转型的个别决定因素

由于大量使用柴火取暖，智利的特木科和帕德雷拉斯卡萨斯存在严重的空气污染问题。地方当局已作出各种努力来提高燃料质量，并对市场进行更严格的监管。经过认证的木柴保证低湿度 (< 25%) 并具有更好的燃烧性，但其分布仍然有限，并且几乎没有研究决定其购买的变量。本研究的目的是确定智利南部城市认证木柴消费的决定因素。本研究采用横断面非实验设计。在方便的非概率抽样之后，我们对使用柴火系统的参与者进行了 355 次调查。进行了非参数比较分析，以确定社会人口统计变量在使用认证木材方面的差异。此外，使用序数逻辑回归来分析认证木柴的使用与各种心理社会变量之间的关系。参与该研究的燃木炉灶用户中有一半声称他们“从不”（38%）或“几乎从不”（12%）使用经过认证的木柴来取暖。情境变量和产品相关变量，如价格、可用性、便利性和时间是人们购买行为的基础，部分解释了该产品表现出的低公众兴趣。另一方面，结果表明社会人口变量的影响，如收入水平和家里的老年人，以及心理社会变量，包括参与者对空气质量的关注程度、他们对空气质量的了解程度、空气污染引起的不适感以及对空气污染对健康影响的关注。首先，有必要通过宣传活动提高民众的信息水平和意识，以促进智利南部可持续的城市能源转型。其次，信息战略可以通过促进就业、推动投资、提高收入和加强社会保护机制，尤其是对最弱势群体的社会保护机制加以补充，以使其有效。最后，保护和刺激正式的木柴贸易可以增加经过认证的木柴的销售点，这将有助于用户获得更清洁的燃料。
