Greenhouse Gas Emissions

The monthly Greenhouse Gas (GHG) emission data represents Montgomery County Facilities and Fleet by month beginning July 2019. The original publisher is dataMontgomery (ata.montgomerycountymd.gov). The dataset was first published in May 5, 2020. The data owner is the Service Department of General Services, Division of Enterprise Management Systems and Business Solutions (svc dmesb) in Montgomery County of Maryland.<br>Facilities: The Facilities GHG data represents physical structures used by County residents and County staff who provide services for County residents. Examples include recreation, libraries, theater and arts, health and human services, liquor retail, courthouses, general services, maintenance facilities, correctional facilities, police stations, fire stations, volunteer fire stations, garages, parking lots, bus shelters and park &amp; ride locations. Facilities GHG data DOES NOT include Public Schools, Montgomery College and Montgomery Parks. Fleet: The Fleet GHG data represents Montgomery County vehicles used by staff who provide services for residents. Examples include mass transit buses, snowplows, liquor trucks, light duty trucks, police cars, fire service equipment, etc.<br>Fleet GHG data DOES NOT include Montgomery County Public School buses, Montgomery College and Montgomery Parks vehicles. GHG Calculation Method: Facilities and Fleet fuel sources are converted into one common unit of energy- 1 Million British thermal units (MMBtu) which are then used with emissions factors and 100-year global warming potential (GWP) to calculate GHG emissions into one common unit of measure- Metric Tons of CO2 Equivalent (MTCO2e).

本数据集为2019年7月起的蒙哥马利县设施与车队月度温室气体（Greenhouse Gas, GHG）排放数据。原始发布方为dataMontgomery（ata.montgomerycountymd.gov），首次发布时间为2020年5月5日。数据所属方为马里兰州蒙哥马利县总务部企业管理系统与业务解决方案处（svc dmesb）服务部门。

设施类温室气体数据：涵盖为县内居民及服务居民的县工作人员所使用的实体建筑，具体包括休闲场馆、图书馆、剧院与艺术场馆、健康与公共服务机构、酒类零售店、法院、总务设施、运维设施、惩教设施、警察局、消防站、志愿消防站、车库、停车场、公交候车亭及通勤拼车站点等。本设施类温室气体数据不包含公立学校、蒙哥马利学院及蒙哥马利公园相关设施。

车队类温室气体数据：涵盖为居民提供服务的县工作人员所使用的蒙哥马利县公务车辆，具体包括公交巴士、除雪车、酒类配送卡车、轻型卡车、警用车辆、消防作业装备等。本车队类温室气体数据不包含蒙哥马利县公立学校校车、蒙哥马利学院及蒙哥马利公园所属车辆。

温室气体核算方法：将设施与车队的燃料来源统一转换为百万英热单位（1 Million British Thermal Units, MMBtu），随后结合排放因子与百年尺度全球变暖潜势（Global Warming Potential, GWP），将温室气体排放量统一折算为二氧化碳当量公吨（Metric Tons of CO2 Equivalent, MTCO2e）。如需获取更多信息，可访问以下渠道：
