A comprehensive accounting of Scope 1, 2, and 3 carbon emissions reveals significant disparities between Chinese cities, highlighting the need to address indirect emissions for effective climate strategies. This sustainability research insight is drawn from a 2025 study published in Scientific Data. Using Methodological model construction and dataset creation, researchers explored how this design variable affects real-world outcomes. The key design takeaway: When designing for sustainability, explicitly account for Scope 3 emissions in addition to Scope 1 and 2 to ensure comprehensive impact assessment and effective strategy development.
Scope 3 emissions are a critical, often overlooked, component of urban carbon footprints.

Scientific Data · 2025
Key Findings
- 01Significant quantitative and spatial differences exist in total carbon emissions across Chinese cities in 2023.
- 02The top 10 emitting cities have emissions 90 to 160 times higher than the bottom 10 cities.
- 03Cities with high Scope 1 and 2 emissions are concentrated in southeastern coastal areas.
- 04Cities with high Scope 3 emissions are concentrated in rapidly developing central China.
Application
Design takeaway
When designing for sustainability, explicitly account for Scope 3 emissions in addition to Scope 1 and 2 to ensure comprehensive impact assessment and effective strategy development.
How to apply
When assessing the environmental impact of a product, service, or urban system, map out not only direct emissions but also those embedded in supply chains and end-of-life disposal or consumption.
Project actions
- 01When researching a design problem, look for data that includes indirect impacts (Scope 3) if available.
- 02Consider how your design choices might influence emissions beyond your immediate control, such as through material sourcing or user behaviour.
Method & Evidence
Variables
Strengths & Limitations
Strengths
- +Provides a full-scope (Scope 1, 2, and 3) dataset, addressing a gap in existing research.
- +Offers city-level data, enabling detailed analysis and comparison.
Limitations
Gathering accurate Scope 3 data can be challenging due to its indirect nature and reliance on external factors.
Reliability & validity
The reliability and validity of the dataset depend on the robustness of the methodological model and the quality of the input data used for emission calculations.
Think critically
How might a designer influence Scope 3 emissions through product design choices, even if they don't directly control the manufacturing or disposal processes?
Design Principles
"Embrace a full-scope perspective in sustainability design, considering direct, indirect, and consumption-based environmental impacts."
Understanding the full spectrum of carbon emissions, including Scope 3 (indirect emissions), is essential for developing holistic and effective sustainability strategies. Design interventions that focus solely on direct emissions may miss significant opportunities for environmental impact reduction.
What This Means for Your Design
Even if a city or product doesn't directly produce a lot of pollution, the things it buys or uses might, and that counts towards its total environmental impact.
How to use in your project
- 1.Reference this study when discussing the importance of a holistic approach to environmental impact assessment in your design project.
- 2.Use the findings to justify the inclusion of lifecycle assessment or supply chain analysis in your research.

Paragraph starter
The comprehensive accounting of carbon emissions, including Scope 3, is crucial for effective environmental strategy development, as demonstrated by studies on urban carbon footprints which reveal significant indirect impacts often overlooked in traditional analyses. This highlights the necessity for designers to consider the full lifecycle and supply chain implications of their work.
