骨料是需求量很大的天然材料。它们直接用于建筑或作为预拌混凝土或沥青产品的成分，并作为一个国家经济活动的指标。采石场和需求点之间的距离控制着骨料等高地方价值产品的价格。它们的潜在开发取决于地质、环境和遗产保护法等因素，甚至取决于人口稠密地区附近的社会排斥。这些因素迫使采石场搬离需求区域，使骨料需要运输更远的距离，从而带来相关的经济、环境和安全问题。许多作者根据看法指出骨料采石场逐渐远离需求区域，但没有支持这一假设的估计。这项工作研究了 1995 年至 2018 年期间供应马德里地区骨料需求的采石场的位置。该研究证明了采石场的逐渐疏远，甚至将部分生产转移到邻近省份。由于距离和相关的二氧化碳排放而导致的超额行驶公里数已被估计。尽管普遍认为“不要在我的后院”（NIMBY）现象是导致采石场远离需求区的原因，但事实证明，马德里地区的主要原因不是公民的反对，而是人口因素和不同的土地使用限制的结合。
Aggregates are natural materials of great demand. They are directly used for construction or as constituents of ready-mixed concrete or asphalt products, and they appear as an index of the economic activity of a country. Distance between quarries and demand points controls the price of high place-value products such as aggregates. Their potential exploitation depends on factors such as geology, environmental and heritage protection laws, or even on social rejection near populated areas. These factors are forcing quarries to move away from demand areas and make the aggregates to be transported for longer distances, with associated economic, environmental, and safety issues. Many authors have indicated the progressive distancing of the aggregates quarries from to the demand areas based on perceptions but without estimations supporting this hypothesis.This work has studied the location of the quarries supplying the demand of aggregates of Madrid region in the period 1995–2018. The study proves the progressive distancing of the quarries and even the relocation of part of the production to neighboring provinces. The kilometers travelled in excess due to the distancing and the associated CO2emissions, have been estimated. Despite the general opinion that the “Not in My Backyard” phenomenon (NIMBY) was the cause of the distancing of the quarries from the demand areas, it has been found that the main reason in the case of the Madrid region is not the opposition of the citizens but a combination of demographic factors and different land use restrictions.
