一个可操作的方法，包括土地利用的影响，在LCA已经制定。其目的是将这一方法建立在科学框架的基础上，并利用科学数据得出指标分数。这就产生了全球一级每种土地利用类型的第一套粗略影响评分数据，涉及两项指标。其余的主观因素与方法的限制有关：只选择两个指标作为表示土地使用影响的基础（维管植物物种多样性和自由初级生物量净生产），必须包括一个参考状态，以纳入区域差异，生物多样性的衡量标准是相对于当地背景生物多样性的，导致对变化的敏感性相对较低。最后，土地利用的影响被认为与土地面积成比例，这是LCA中的共识，但并不总是一致的。很明显，这种运作目前只是在其十几岁。
An operational method to include land use impacts in LCA has been developed. The aim was to base the approach on a scientific framework and to use scientific data to arrive at indicator scores. This has led to a first set of rough impact score data per type of land use on a global level, for two indicators. Remaining subjective elements are related to the restrictions of the approach: only two indicators are chosen as a basis for expressing land use impacts (vascular plant species diversity and free net primary biomass production), a reference state had to be included to incorporate regional differences, and for biodiversity the measure is relative to the local background biodiversity, leading to relatively low sensitivities to changes. Finally, land use impacts are considered to be proportional to the area which is a common understanding in LCA, but not always agreed upon. It is clear that this operationalisation is at present only in its teens.
