Sustainable Practices & Conservation Flashcards

Which co-benefit of air pollution control policies is most directly linked to reducing PM₂.₅ emissions?

Answer: Reduced premature mortality and healthcare costs from respiratory and cardiovascular disease

PM₂.₅ penetrates deep into the lungs and bloodstream; reducing it yields direct public health co-benefits including fewer premature deaths and lower healthcare expenditures.

A community air monitoring network using low-cost sensors supports environmental justice goals by:

Answer: Providing real-time, hyperlocal air quality data to historically underserved communities

Low-cost sensor networks enable community-scale, real-time monitoring that empowers residents in environmental justice communities to identify and address local pollution hotspots.

Electrification of port equipment (cranes, yard tractors) as a sustainable practice primarily reduces emissions of:

Answer: NOₓ and PM from diesel combustion near sensitive coastal communities

Port equipment electrification eliminates on-site diesel combustion, directly reducing NOₓ and PM emissions that disproportionately affect nearby communities.

A 'just transition' framework for retiring coal-fired power plants includes air quality considerations because:

Answer: It plans for phased closure with worker retraining and community air quality improvement simultaneous with economic transition

A just transition addresses both the economic displacement of workers and the ongoing air quality improvement for communities, ensuring neither goal is sacrificed for the other.

Extended producer responsibility (EPR) policies for solvents and coatings advance air quality sustainability by:

Answer: Requiring manufacturers to fund consumer-return programs reducing improper VOC disposal and evaporation

EPR programs make manufacturers responsible for end-of-life product management, encouraging take-back and safe disposal that reduces uncontrolled VOC evaporation from improper disposal.

Methane leak detection and repair (LDAR) programs at natural gas facilities support air quality because methane:

Answer: Is a potent greenhouse gas and precursor to tropospheric ozone formation

Methane is a potent greenhouse gas (GWP ~84 over 20 years) and reacts in the atmosphere to contribute to tropospheric ozone formation, making LDAR programs beneficial for both climate and air quality.

The concept of 'air quality co-benefits' in climate policy refers to:

Answer: Local air quality improvements gained as a secondary benefit of actions primarily targeting greenhouse gas reductions

Co-benefits are the ancillary local air quality improvements (e.g., reduced PM, NOₓ) that result from climate mitigation actions like fuel switching or efficiency improvements.
