London Energy and Greenhouse Gas Inventory (LEGGI) 2012

London Energy and Greenhouse Gas Inventory (LEGGI) 2012 showing greenhouse gas emissions and energy consumption for London. The is the interim version of the LEGGI 2012, which will be confirmed when final confirmed data on energy use is published by the Department of Energy and Climate Change (DECC), expected in 2015. LEGGI shows estimates of energy consumption and carbon dioxide (CO2) emissions from Homes, Workplaces and Transport within the Greater London area. It is produced by the Greater London Authority on an annual basis to measure progress against the Mayor's Climate Change Mitigation and Energy Strategy. LEGGI uses sub-regional energy (electricity, gas and other fuels) and CO2 data published by DECC for Homes and Workplaces, and data from the London Atmospheric Emissions Inventory (LAEI) for energy and CO2 data for Transport. Interim results show that in 2012, emissions in London were 40.75 MtCO2e. This is a 10% reduction from 1990 figures and a 19% reduction since their peak in 2000. CO2e levels have increased by 4.5% (1.76 MtCO2e) from 2011 to 2012 (38.99 to 40.75 MtCO2e respectively). It is estimated this is due to an increase in the CO2e intensity of the electricity grid, increased gas use due to a cold winter in 2012 and an increased population in London.

伦敦能源与温室气体清单（LEGGI）2012版，展示了伦敦地区的温室气体排放与能源消耗情况。此为LEGGI 2012的临时版本，待能源与气候变化部（DECC）发布关于能源使用的最终确认数据后，预计于2015年进行确认。LEGGI展示了大伦敦区域内住宅、工作场所和交通领域的能源消耗与二氧化碳（CO2）排放的估计数据。该清单由大伦敦管理局每年编制，旨在衡量市长气候变化减缓与能源战略实施进展。LEGGI采用能源（电力、天然气及其他燃料）和CO2数据，这些数据由DECC针对住宅和工作场所发布，以及来自伦敦大气排放清单（LAEI）的交通能源与CO2数据。临时结果显示，2012年伦敦的排放量为40.75MtCO2e，较1990年下降10%，自2000年峰值以来下降19%。从2011年到2012年，CO2e水平上升了4.5%（1.76MtCO2e），从38.99MtCO2e增至40.75MtCO2e。估计这一变化是由于电力网格的CO2e强度增加、2012年冬季寒冷导致的天然气使用增加以及伦敦人口增长所致。
