新研究显示，中国来自农业机械的碳排放快速增长，可能会“阻碍”该国实现净零排放的目标。 这项发表在《自然-食品》（Nature Food）期刊上的研究发现，自1985年以来，中国农业机械CO2（二氧化碳）排放量增加了大约七倍。 研究人员利用政府发布的不同时期农机数量统计数据，计算了1985年至2020年期间CO2排放量及其他空气污染物的变化。 他们发现，自1985年以来，农业机械的CO2排放量平均每年增长近6%。 研究指出，按照中国实现2060年净零排放目标的路径，若农业机械化程度按“预期趋势”继续提升，其相关排放在2050年可能占中国总排放量的21%。 上微信关注《碳简报》 作者表示，这可能会使中国实现减排目标更加困难，并导致空气质量“恶化”。 然而，研究还发现，如果广泛采用由可再生能源驱动的农业机械，有望减少65%至70%的相关排放。 一位未参与该研究的专家对Carbon Brief表示，尽管该研究“具有价值”，但农业机械不太可能在总排放量中占到如此高的比例。 “如果中国在减少其他排放源方面取得了快速进展……那么我预计在农业机械的脱碳方面也会取得显著成效。”她说。 农机相关排放 粮食系统大约占人类温室气体排放的三分之一。 这一数字涵盖了与粮食生产相关的所有排放——从因森林砍伐或土地使用变化导致的排放，到奶牛打嗝或粪便释放的甲烷。…
