This report presents a high-detail Product Carbon Footprint (PCF) analysis for the BYD Atto 3 Essential 2025 model, conducted under the stringent guidelines of the GHG Protocol. The assessment focuses on a factory-gate system boundary for a single unit of the vehicle, with a primary geographic scope of final production in China and an upstream supply chain focus on Oceania and global sources. The objective is to quantify the greenhouse gas (GHG) emissions associated with the production of the vehicle up to the point it leaves the factory, identifying key emission hotspots across its material and energy inputs. Special attention has been paid to the 2026 Land Sector and Removals (LSR) Standard update and the 95% Scope 3 coverage compliance requirements.
The functional unit for this PCF analysis is 1.0 unit of the BYD Atto 3 Essential 2025 electric vehicle.
The system boundary for this analysis is defined as "factory_gate". This encompasses all upstream activities related to the extraction and processing of raw materials, the manufacturing of components, and the transportation of these materials and components to the final assembly plant in China. It also includes the energy consumption and direct emissions (Scope 1 and 2) occurring at the final vehicle assembly factory itself. Emissions associated with the use phase (e.g., electricity consumption during driving) and end-of-life treatment are excluded from this specific system boundary.
The analysis strictly adheres to the GHG Protocol Corporate Accounting and Reporting Standard, supplemented by the Corporate Value Chain (Scope 3) Accounting and Reporting Standard. Furthermore, the analysis considers the implications of the 2026 Land Sector and Removals (LSR) Standard update and the enhanced Scope 3 reporting compliance requirements.
Due to the nature of a product-level PCF, emissions are allocated entirely to the functional unit (one vehicle). Where shared processes occur (e.g., a factory producing multiple vehicle models), emissions are allocated based on mass or economic value as appropriate, though for this high-level analysis, direct material and energy inputs are attributed to the single vehicle.
This section details the primary material and energy inputs for the BYD Atto 3 Essential 2025, based on a comprehensive lifecycle inventory approach. Given the proprietary nature of specific manufacturing data, estimations are derived from publicly available vehicle specifications, industry averages for EV material composition, and established LCA databases.
Based on the curb weight of 1750 kg and assuming a battery pack weight of approximately 300 kg (derived from its 49.9 kWh capacity and typical LFP energy density of ~166 Wh/kg for the pack), the remaining 1450 kg are distributed across other major vehicle components. These estimations are based on general EV industry composition and adjusted for LFP battery chemistry which typically excludes nickel and cobalt in the cathode. Material production is considered "cradle-to-gate".
| Material Category | Estimated Quantity (kg) | Notes / Primary Components |

The final assembly of the BYD Atto 3 Essential 2025 in China requires significant energy, primarily in the form of electricity for robotics, lighting, heating, cooling, and various manufacturing processes (e.g., welding, painting, drying ovens). An estimated 800 kWh of electricity is consumed per vehicle for the assembly process.
Emissions are calculated by multiplying the activity data (material quantities, energy consumption) by appropriate industry-standard emission factors. These factors are sourced from reputable databases such as Ecoinvent and DEFRA, or recognized industry averages, with a focus on regional specificity (China for manufacturing and energy).

*Scope 1 emissions are typically minor for a final assembly plant and are often better captured as upstream emissions from material production. This is a placeholder for any direct, controlled emissions.
**Using a representative factor for upstream electricity emissions (transmission & distribution losses, fuel extraction) which are typically separate from the generation factor for Scope 2.
The GHG Protocol\'s Land Sector and Removals Standard, effective January 1, 2027, provides crucial guidance for accounting for land use change, land management, and biogenic CO2 removals. While this standard specifically targets entities with significant land sector activities (e.g., agriculture, forestry, or those engaged in CO2 removals), its relevance to automotive PCF lies in the upstream supply chain of raw materials. Key materials like lithium, steel (iron ore), and aluminum (bauxite) are derived from mining, an activity with potential land-use change impacts. For a high-detail PCF analysis, the LSR Standard would necessitate:
For this specific report, without granular primary data on the land footprint of each raw material\'s extraction site, these emissions are implicitly included within the "cradle-to-gate" emission factors of the materials. A full application of the LSR Standard would require deeper supply chain transparency to identify and quantify specific land-related impacts for each material. The accompanying Guidance document, expected in Q2 2026, will provide more practical direction for implementation.
The GHG Protocol\'s 2026 requirements emphasize at least 95% coverage for Scope 3 reporting. For this factory-gate PCF, the vast majority of emissions are indeed categorized under Scope 3 (Purchased Goods and Services, Fuel- and Energy-Related Activities, Upstream Transportation). By meticulously estimating the emissions from all major material inputs and their transportation, this analysis aims to meet or exceed this 95% threshold for the defined system boundary. Remaining minor categories (e.g., capital goods not directly tied to the product, business travel for product development) are acknowledged but considered immaterial for this specific product-level factory-gate assessment. The use of robust, albeit sometimes averaged, emission factors for the primary materials ensures significant coverage.
The PCF analysis reveals the following major emission hotspots for the BYD Atto 3 Essential 2025 (factory-gate boundary):
This report is based on a high-level assessment utilizing secondary data, industry averages, and publicly available specifications. While efforts were made to use region-specific and up-to-date emission factors (e.g., for Chinese electricity and LFP battery production), certain limitations exist:
