Activity-Based Emissions Systems Intelligence

World Emission Network (WEN) develops high-resolution, activity-driven emissions intelligence to quantify how economic and infrastructure systems generate air pollution and greenhouse gases. Our framework links real-world activity data—energy use, transport movement, industrial output, agricultural practices, and household fuel consumption—to spatially and temporally resolved emissions inventories.

We model how these activities interact across sectors and boundaries, identifying structural emission drivers and intervention points capable of delivering measurable system-wide reductions.

Core Analytical Framework

🔹 Activity-to-Emission Quantification

Translate sectoral activity data into source-linked emissions profiles with district- and city-scale resolution.

🔹 Spatial & Temporal Inventory Development

Construct high-resolution emissions inventories with seasonal differentiation and cross-boundary accounting.

🔹 Systems Integration

Model interactions across energy, transport, industry, agriculture, and household sectors within a unified emissions framework.

🔹 Transboundary & In-Boundary Analysis

Quantify local emissions alongside regional inflows to determine true contribution patterns.

🔹 Intervention Scenario Modeling

Simulate how fuel transitions, electrification, regulatory shifts, and technology adoption alter emissions across the full system.

From Micro-Level Activity to Structural Emission Reduction

Air pollution and climate risk emerge from interconnected systems—not isolated sources. WEN’s approach ensures interventions are evaluated at the system level, reducing emissions structurally rather than shifting them across sectors or jurisdictions.
