In recent years, China has accelerated the development of its standard metrology system for carbon peaking and carbon neutrality. However, as the demand for carbon emission accounting data has surged across regions, sectors, and industries, a series of issues have emerged, including slow data updates, inconsistent accounting standards, and outdated baseline emission factors. Under these circumstances, higher demands are placed on the accuracy, timeliness, consistency, comparability, and transparency of carbon emission statistical data.

 

 

Application Value of Carbon Meter

 

  Carbon emission measurement accuracy has been significantly enhanced: By integrating carbon measurement modules into smart meters, the system can precisely trace carbon emission sources based on actual power transmission conditions, while continuously updating real-time carbon emission data per kilowatt-hour. This enables comprehensive tracking and real-time measurement of carbon emissions across all processes. Real-time monitoring of carbon emission dynamics not only helps power-consuming enterprises better fulfill their carbon emission control responsibilities, but also provides reliable support for relevant authorities to scientifically evaluate emission reduction effectiveness and formulate precise, efficient carbon reduction measures.

 

     Realizing big data-driven management and visualization of carbon emissions: The application of electricity carbon meters can effectively enhance the accuracy and consistency of carbon emission and monitoring data, providing robust data support for comprehensively and systematically understanding the overall carbon emission trends in regions or industries. As a core component of the smart IOT electricity meter framework, electricity carbon meters further elevate the intelligence level of the entire energy management system, driving more efficient, precise, and targeted energy control.

2. Carbon emission settlement function

 

    Twelve carbon emission settlement groups are designated, each corresponding to associated electricity (including combined, forward, reverse, or net active power options) and emission factors.

 

The carbon settlement interface displays 12 sets of carbon emission values with corresponding emission factors. Press the up/down keys to switch between the sets, and right-click to modify the associated electricity consumption and emission factors.

 

 

 

 

Carbon asset management platform

 

  Carbon accounting serves as the cornerstone of carbon asset management. By considering regional environmental variations and industry-specific operational characteristics, it requires precise delineation of accounting boundaries. Customized models with strong adaptability and high accuracy should be developed for diverse scenarios including industrial parks, energy-intensive enterprises, manufacturing plants, and public institutions. The platform also facilitates seamless access to carbon trading market information channels for businesses. Grounded in accurate carbon accounting results and informed by real-time market trends and policy guidance, it assists enterprises in optimizing carbon trading strategies, enabling users to efficiently capture carbon benefits and achieve carbon asset preservation and appreciation.

 

 The Acrel-7000 Enterprise Energy Consumption Management Platform rigorously adheres to carbon asset management principles, providing end-to-end professional services for corporate clients. Integrated with the AEM96 Multi-Function Carbon Meter and other smart meters, it enables comprehensive tracking of carbon emissions throughout production processes, precise calculation of total emission volumes and intensity, and optimization of carbon quota assessment systems. This solution empowers businesses to achieve sustainable energy efficiency, actively support China's "Dual Carbon" strategy, and facilitate green, low-carbon transformation.

 The digital energy management platform serves as the cornerstone of corporate carbon asset management. Its core value lies in advancing energy management from traditional monitoring to comprehensive carbon tracking across all processes, thereby achieving digital transformation in carbon asset management. Tailored to the unique characteristics of different industries and regional environmental variations, it accommodates diverse carbon emission accounting needs, driving standardization in carbon asset management. The platform enables full-process tracking of carbon generation, accounting, and control, enabling refined management of carbon assets. Furthermore, supported by precise data, it assists enterprises in optimizing carbon trading decisions, helping them capture carbon benefits, and elevating carbon asset management to a professional level.

 

   Meanwhile, by proactively conducting carbon footprint assessments and disclosing product-related data, enterprises can not only enhance their products 'green competitiveness and market recognition, but also serve as role models. This initiative encourages upstream and downstream supply chain partners to strengthen environmental awareness and adopt sustainable production practices, ultimately accelerating society's progress toward achieving the "carbon peak and carbon neutrality" goals.

 

 

Data transmission device

 

  The Power Internet of Things (IoT) edge computing gateway collects field data, performs protocol conversion and storage, then transmits it to the platform via Ethernet. With edge computing capabilities, it can store data locally during network failures and resume uploads from the interrupted point upon network recovery, ensuring server-side data integrity.

 

 

 

Conclusion

 

  By leveraging the smart energy management platform, enterprises prioritize the implementation of the "dual carbon" strategy as their core objective. They conduct systematic research to formulate strategic plans, top-level designs, and supporting solutions for achieving carbon peak and carbon neutrality. Concurrently, they establish comprehensive management systems, refine carbon asset evaluation and incentive mechanisms, and ensure orderly execution of all initiatives. Additionally, they actively promote energy-saving and efficiency-enhancing actions, advance the R&D and application of low-carbon innovative technologies, and strengthen the foundation for carbon emission reduction.

 

  We provide end-to-end management and technical services for corporate carbon emission rights compliance and surrender, ensuring full compliance. We facilitate internal carbon quota balancing and adjustment within enterprises, while conducting orderly transactions of carbon emission allowances and voluntary emission reductions in domestic and international carbon markets. Our comprehensive service solutions scientifically optimize emission reduction strategies, control compliance costs, and enhance trading returns, maximizing carbon asset value.

 

  Carry out carbon inventories regularly, standardize the preparation of carbon emission verification reports, carbon trading accounting reports, and comprehensive carbon asset management evaluation reports, to provide data support for optimizing carbon asset management.

 

  In the future, carbon asset management will leverage market-oriented mechanisms as a key driver to boost the industrial application and high-quality development of carbon. It will further strengthen and expand zero-carbon and negative-carbon industrial clusters, playing an increasingly vital role in supporting the implementation of the 'dual carbon' strategy.
