How can the power grid help China build the world's largest and fastest-growing renewable energy system? How can time-sharing and regional electricity-carbon factors accurately reflect users' carbon reduction contributions? How has China's UHV technology crossed mountains and seas to enter Brazil? A series of energy transition practice cases from China have attracted global attention.

At the themed side event, State Grid, together with 51 enterprises and institutions, jointly launched the Brazil Initiative on Global Time-Sharing and Regional Electricity-Carbon Factors. Time-sharing and regional electricity-carbon factors can be used for refined calculation of carbon emissions, more accurately reflecting changes in clean energy power generation output at different times and in different regions. This further effectively guides enterprises to optimize their electricity consumption habits, promote more electricity use during low-carbon periods, help absorb new energy power, reduce product carbon emissions, and drive deep decarbonization of the whole society.

主题边会上，国家电网公司联合51家企业、机构，共同发起《全球分时分区电碳因子巴西倡议》。分时分区电碳因子可以用于精细测算碳排放量，更准确地反映清洁能源发电出力在不同时刻、不同地域的变化，进而有效引导企业优化用电习惯，促进低碳时段多用电，助力新能源电量消纳，降低产品碳排放，推动全社会深度脱碳。

"State Grid's launch of the initiative will promote the establishment of science-based carbon targets and enhance the green competitiveness of enterprise products," said Dominic Waughray, Executive Vice President of the World Business Council for Sustainable Development (WBCSD).

“国家电网公司发起倡议，将推进基于科学的碳目标建立，同时推动企业产品提升绿色竞争力。”世界可持续发展工商理事会执行副会长多米尼克·沃格雷表示。

"This initiative is forward-looking and will play an important role in accelerating the decarbonization process of the energy system," said Karen Silverwood-Cope, Director of the Climate Department at the World Resources Institute (WRI) Brazil Office.

“这个倡议富有远见，将对加速能源系统的脱碳进程起到重要作用。”世界资源研究所巴西办公室气候部门主任卡伦·西尔弗伍德·科普说。

The global electricity-carbon factor map platform released at the themed side event intuitively showed the role of time-sharing and regional electricity-carbon factors to participating guests. On the 3D map, the flow of energy, power grid transmission, and carbon emission trends were displayed in real time: at 13:00 Beijing time, when the sun shines on eastern Asia, the global electricity-carbon factor hit the lowest value of the day; by 01:00 Beijing time, when the sun moves to the Pacific Ocean, the global electricity-carbon factor rises to a high point. This fully confirms China's photovoltaic power generation contribution to global carbon emission reduction.

在主题边会上发布的全球电碳因子一张图平台，向与会嘉宾直观展示了分时分区电碳因子的作用。三维地图上，能源流动、电网传输与碳排放的流向实时展示：北京时间13时，当阳光照耀亚洲东部，全球电碳因子创下当日最低值；而到北京时间1时，阳光移至太平洋，全球电碳因子升至高点。这充分印证了中国光伏发电对全球碳减排的贡献。

Against the backdrop of entering a new stage of energy and greenhouse gas accounting, innovation and collaboration have become the keys to promoting a credible and replicable climate process.

在进入能源与温室气体核算新阶段的大背景下，创新与协作成为推动可信且可复制的气候进程的关键。

"Carbon accounting needs to achieve more precise calculations in time and space," said Alex Pereira, Deputy Director of the WRI's Bolsky Center for Global Energy Transition. "The carbon accounting method launched by State Grid is timely and meets the needs of the times. We look forward to seeing the standards formulated by China implemented in other countries."

“碳核算需要在时间和空间上实现更加精确的计算。”世界资源研究所波尔斯基全球能源转型中心副主任艾利克斯·佩雷拉说，“国家电网公司推出的碳核算方法很及时，也符合时代需求。我们期待看到中国制定的标准可以在其他国家落地。”

The value of data has also attracted much attention. "Now, data accessibility is getting better and better. Using intelligent technologies to achieve high-quality data governance and value mining is the future trend. The time-sharing and regional electricity-carbon factors launched by State Grid are of great innovation," said Julio Natalense, Business Development Manager of the Sustainability Department at SGS (Latin America). He believes that more refined carbon accounting methods can help enterprises better plan green power use and make enterprise operations more in line with low-carbon expectations.

数据的价值也备受关注。“现在，数据的可及性越来越好，运用智能化技术实现数据的高质量治理与价值挖掘是未来的趋势。国家电网公司推出的分时分区电碳因子具有重要创新性。”瑞士通用公证行（拉丁美洲）可持续发展部商务拓展经理朱利奥·纳塔伦塞认为，更精细的碳核算方法能帮助企业做好绿电使用规划，使企业运营的情况更加符合低碳预期。

In recent years, State Grid has served the implementation of national strategies, built a power carbon emission accounting system, deepened green power and green certificate transactions, strengthened power carbon footprint management, and guided the whole society to improve green power consumption levels.

近年来，国家电网公司服务国家战略实施，构建电力碳排放核算体系，深化绿电绿证交易，加强电力碳足迹管理，引导全社会提升绿色电力消费水平。

Many participating guests said that State Grid is providing a "Chinese solution" for energy transition with an open and shared attitude. This is not only the sharing of technological innovation experience but also provides a replicable model for carbon reduction in many developing countries.

多位与会嘉宾表示，国家电网公司正在以开放共享的姿态提供能源转型的“中国方案”，这不仅是技术创新的经验分享，还为许多发展中国家减碳提供了可复制的样本。
