碳排放精准表征

CEADs团队发布中国182城市碳排放清单: 在《科学·进展》发文讨论各城市工业化进

CEADs团队发布首批由"共筹、共建"形式编制的中国182城市2010年碳排放清单。此清单编制、校验历时两年有余。清单由近百位各研究机构老师、同学先后无偿的热心参与与联合校验。城市尺度碳排放清单与国家、省区级排放清单保持高度的一致性，具有相同核算口径、数据来源、清单格式等。所核算的二氧化碳排放量包含17种化石燃料以...

CEADs研究：中国出口产品的隐含碳排放达峰

国际贸易引起的碳排放占全球碳排放的20%以上。发达国家的消费会引起发展中国家的碳排放。出口是促进中国经济发展的三驾马车之一，但同时也是导致了大量碳排放增长。进入新常态后，中国经济发展模式发生了很大转变，国际贸易中的地位也在变化。在此背景下，CEADs团队发表在地学领域顶级期刊Geophysical Research Letters上发表最新成...

The spatiotemporal features of greenhouse gases emissions from biomass burning in China from 2000 to 20

Greenhouse gases emissions from biomass burning have been given a little attention, especially the spatiotemporal features of biomass burning sources and greenhouse gases emissions have not been comprehensively uncovered. This research undertook IPCC bottom-up inventory guideline to estimate Chinese greenhouse gases emissions from biomass burning and applied geographical information system to reveal biomass burning emissions spatiotempo...

Carbon emission imbalances and the structural paths of Chinese regions

As the Chinese regions become more and more connected to each other and foreign countries, this study aims to address carbon imbalance and outsourcing issues in China. Using a production-based carbon emission inventory and a China-global multi-regional input-output model, this study estimates the consumption-based carbon emissions in 30 Chinese regions in 2007 and 2010. Our results reveal that the carbon imbalances of most Chinese provin...

CEADs数据：能源统计数据多次修正对碳减排目标达成的影响

作为世界第一大能源消费国与碳排放国，中国在达成全球减排目标中扮演着至关重要的角色。为此，中国政府推行强有力的减排措施，并向世界做出自主减排承诺：在2020年前与2030年前将其碳强度相比2005年水平分别降低40-45%与60-65%（40/45与60/65目标），并在2030年前实现碳排放达峰。这些减排目标的实现离不开准确、一致地国家能源消费...

CEADs在Nature旗下期刊《科学数据》撰文：发布中国1997-2015二氧化碳排放清单

数据是气候变化领域工作的基础，准确的衡量国家与区域的二氧化碳排放量是后续相关研究与低碳减排政策制定的前提。在巴黎协定中，碳排放数据的透明性(transparency)、准确性(accuracy)、完整性(completeness)、可比性(comparability)和一致性(consistency)被正式列入提案。 CEADs数据库长期致力于打造公开、透明、可比较、可验证、全免费的中国碳...

Patterns of CO₂ emissions in 18 central Chinese cities from 2000 to 2014

With the Rise of Central China Plan, the central region has had a great opportunity to develop its economy and improve its original industrial structure. However, this region is also under pressure to protect its environment, keep its development sustainable and reduce carbon emissions . Therefore, accurately estimating the temporal and spatial dynamics of CO 2 emissions and analysing the factors influencing these emissions are especiall...

China CO₂ emission accounts 1997–2015

China is the world’s top energy consumer and CO 2 emitter, accounting for 30% of global emissions. Compiling an accurate accounting of China’s CO 2 emissions is the first step in implementing reduction policies. However, no annual, officially published emissions data exist for China. The current emissions estimated by academic institutes and scholars exhibit great discrepancies. The gap between the different emissions estimates is ap...

CEADS团队发文揭示全球高污染发电机组的排放贡献并发布基于机组的全球火电厂排

化石能源使用过程中排放的温室气体及大气污染物对气候变化、空气质量和人体健康造成严重影响。电力行业的化石能源消费量约占全球消费总量的50%左右，是全球温室气体减排和大气污染控制的最主要目标之一。可监测、可报告、可核查是国际社会对于污染源排放和减排监测的基本要求，然而由于相关基础数据长期不透明、不公开，...

Multi-scale input-output analysis of consumption-based water resources: Method and application

This work develops a method of multi-scale input-output analysis for the embodied water accounting of an economy. This method can distinguish between the different virtual water contents of imported and local products and is therefore capable of estimating the virtual water that is embodied in trade. As a simplified model rather than a multi-regional input-output analysis, this method substantially minimizes the data requirements. With t...
