Calculation procedure

6.2.1 Data collection of crude steel production

A plant manufacturing steel records its annual production of crude steel (P).

The section 6.2.2 emphasizes the importance of identifying and collecting data on direct and upstream CO₂ emission sources imported from external suppliers, as outlined in Table 2 Accurate data collection on these emission sources is essential for comprehensive greenhouse gas accounting and environmental impact assessments This approach aligns with ISO 2013 standards, ensuring consistent and reliable reporting of direct and upstream CO₂ emissions.

The annual CO₂ emissions (E′ǡ) and CO₂ intensity of a site are calculated using Equations (1) and (2), which incorporate CO₂ emission factors corresponding to direct emission sources and credit CO₂, as outlined in sections 6.2.2 and 6.2.3 These calculations help quantify the site's total greenhouse gas impact, supporting accurate environmental reporting and sustainability assessments Understanding both the emissions and credits allows for a comprehensive evaluation of a site's carbon footprint and effectiveness of emission reduction measures. -**Sponsor**Need help making your article shine and comply with SEO rules?
