What is Black Carbon Emissions Inventory?
Black Carbon Emissions Inventory compiles global and regional estimates of black carbon emissions from vehicles using emission factors, activity data, and source apportionment techniques.
This subtopic quantifies black carbon (BC) and organic carbon (OC) from on-road and off-road vehicles within broader combustion inventories. Bond et al. (2004) established a technology-based global inventory with 2643 citations, including fossil fuel and biofuel sources. Subsequent works like Zhang et al. (2009) and Ohara et al. (2007) refined Asian vehicle emissions data.
Why It Matters
Vehicle black carbon contributes to climate forcing and air quality degradation, enabling targeted policies like China's clean air actions that reduced emissions (Zheng et al., 2018; Zhang et al., 2019). Accurate inventories support short-lived climate pollutant mitigation, informing diesel exhaust regulations (Birch and Cary, 1996). Global assessments drive technology adoption, such as exhaust aftertreatment systems (Reşitoğlu et al., 2014).
Key Research Challenges
Emission Factor Uncertainty
Vehicle-specific BC emission factors vary by engine type, fuel, and aftertreatment, complicating inventory accuracy (Bond et al., 2004). Real-world measurements near highways reveal ultrafine particle discrepancies (Zhu et al., 2002). Standardization across regions remains unresolved (Ohara et al., 2007).
Source Apportionment Gaps
Distinguishing vehicle BC from other combustion sources requires advanced modeling, challenged by chemical complexity (Birch and Cary, 1996). Asian inventories highlight biofuel contributions needing better separation (Zhang et al., 2009). Temporal trends post-policy changes add complexity (Zheng et al., 2018).
Global Inventory Scaling
Scaling local vehicle data to global levels faces data scarcity in developing regions (Bond et al., 2004). Integrating historical and future projections demands consistent methodologies (Ohara et al., 2007). Policy-driven emission shifts require frequent updates (Zhang et al., 2019).
