A massive fiscal 2018 federal spending bill unveiled by congressional leaders Wednesday night includes a provision urging the heads of EPA, the Energy Department and the Agriculture Department to adopt policies that “reflect the carbon-neutrality of forest bioenergy and recognize biomass as a renewable energy source.” The language has appeared in similar forms in previous spending bills the last few years, due to pressure from lawmakers in forest-heavy states.国会领导人星期三晚上公布了一项2018大规模财政支出法案。法案包括一项条款，敦促环保署、能源部和农业部的负责人采取政策来“说明森林生物能源的碳中性，并承认生物质能源是一种可循环利用的能源”的政策。过去几年，这样的话语以类似的形式也出现在先前的财政支出法案中，森林资源较为丰富的州的法律制定者对此施加了压力。But scientists have been expressing concern for years about the emissions produced by burning biomass. Many experts suggest that declaring wood burning a carbon-neutral form of energy is not only inaccurate, but a potential step backward for global climate change mitigation efforts.但是科学家们多年来一直在关注燃烧生物材料所产生的排放物。许多专家认为，宣布燃烧木材是一种碳中性形式的能源，这不仅是不准确的，而且对于为缓解全球气候变化所作出的努力而言，这可能意味着倒退。express concern for … 关注……；表达对……的关注mitigation / ˌmitiˈɡeiʃn / n. 缓解；减轻But scientists have been expressing concern for years about the emissions produced by burning biomass.

He said that “recent evidence shows that the use of wood as fuel is likely to result in net CO2 emissions.”
