Greater Philadelphia Energy Use and Greenhouse Gas Emissions Inventory

Energy Use and Greenhouse Gas Emissions Inventory for Greater Philadelphia https://www.dvrpc.org/Products/18018 Energy Use is defined as the BBTU (Billion British Thermal Units) equivalent of energy consumed by end point users. For electricity this is the BBTU equivalent of the electricity at point of consumption, not the heat content of the fuels used for electricity generation. Emissions (MTCO2E - Metric tons of carbon dioxide equivalent) from the following sectors and fuel sources are not included in this allocation: enteric fermentation and manure management; commerical and general aviation; marine and port-related activity; off-road vehicles and equipment; freight and intercity passenger rail; coal; fuels used predominently in the industrial sector (e.g., petroleum coke); and land use, land use change, and forestry. Population and Employment data used in this analysis came from DVRPC's Municipal-level Poulation and Employment Forecasts. GEOID_10 - Unique GIS ID for Municipality. ACRES - Total Municipal Acres. USEACRES - Energy Use per Acres (BBTUs). EUPOPEM - Energy Use per Person/Job (BBTUs). EMIACRE - GHG Emissions per Acre (MTCO2E). EMPOPE - GHG Emissions per Person/Job (MTCO2E). EMSQACRE - GHG Emissions/Sequestration including Land Use, Land Use Change, and Foresty per Acres (MTCO2E). EMSQPOPE - GHG Emissions/Sequestration including Land Use, Land Use Change, and Foresty per Person/Job (MTCO2E). DVRPC estimates that net GHG emissions decreased 10 percent from 2010 to 2015, from emissions equivalent to the release of 82 million metric tons of carbon dioxide (MMTCO2e) to about 74 MMTCO2e. GHG emissions were 21 percent lower in 2015 than in 2005. The top three drivers of reductions between 2010 and 2015 were, in decreasing levels of significance, change in electricity generation mix (a cleaner electricity grid due to the continued switch from coal to natural gas), decreased on-road emissions per mile traveled, and decreased electricity consumption per household. Continued reductions will require sustained, concerted and aggressive action at the household, firm, community, regional, state, national, and global level, as well as continued technical advancement.

GEOID_10：市级行政区唯一GIS标识码 2. ACRES：市级行政区总英亩数 3. USEACRES：单位英亩能源使用量（BBTU） 4. EUPOPEM：单位人口/就业岗位能源使用量（BBTU） 5. EMIACRE：单位英亩温室气体排放量（MTCO2E） 6. EMPOPE：单位人口/就业岗位温室气体排放量（MTCO2E） 7. EMSQACRE：单位英亩温室气体排放/固碳量（含土地利用、土地利用变化与林业活动，MTCO2E） 8. EMSQPOPE：单位人口/就业岗位温室气体排放/固碳量（含土地利用、土地利用变化与林业活动，MTCO2E） 德拉瓦河谷区域规划委员会（DVRPC）估算，2010年至2015年期间，温室气体净排放量下降10%，从相当于8200万公吨二氧化碳当量（MMTCO2e）的排放水平降至约7400万公吨二氧化碳当量。2015年的温室气体排放量较2005年降低21%。2010年至2015年期间，推动排放量下降的前三大因素按影响程度从高到低依次为：发电结构优化（因持续从煤炭转向天然气而形成的更清洁电网）、单位行驶里程道路排放量下降，以及每户家庭电力消耗量降低。 若要实现排放量的持续下降，需在家庭、企业、社区、区域、州、国家乃至全球层面开展持续、协调且有力的行动，同时推动技术的持续进步。更多相关信息可查阅：www.dvrpc.org/EnergyClimate/Inventory.htm。如需了解分析方法与数据来源的详细细节，请参考德拉瓦河谷区域规划委员会（DVRPC）发布的《大费城地区能源使用与温室气体排放清单：方法与数据来源》，详情访问：https://www.dvrpc.org/Products/TM18023。
