Air pollution (CDMX)

Air pollution (CDMX)

1. People Contributing to Unsustainability

   • Private car users
     • Dependence on cars instead of public transport increases emissions.
   • Industries & factories
     • High emissions from production processes (often non-compliant with standards).
   • Public transport in poor condition
     • Old buses, minibuses, and taxis that run on low-quality fuels.
   • Government & institutions (lack of enforcement)
     • Weak enforcement of emission standards, limited incentives for cleaner mobility.

2. Government and its secretaries

   • SEMARNAT (Secretaría de Medio Ambiente y Recursos Naturales)
     • regulates
       • national environmental policy and emissions standards
   • SEDEMA CDMX (Secretaría del Medio Ambiente de la CDMX)
     • implements
       • local programs like “Hoy No Circula”
         • reduces private vehicle use
   • SSA (Secretaría de Salud)
     • tracks health impacts
       • of air pollution through respiratory illness data

3. Laws and policies issues by government

   • Ley General del Equilibrio Ecológico y la Protección al Ambiente (LGEEPA)
     • regulates
       • emissions standards
   • ProAire CDMX
     • implements measures
       • public transport policies
   • Normas Oficiales Mexicanas (NOMs)
     • sets limits
       • PM2.5 levels in CDMX air

4. People affected by impacts

   • Children and elderly
     • More vulnerable to respiratory illnesses (asthma, bronchitis) and cardiovascular problems.
   • People with pre-existing conditions
     • Those with asthma, allergies, or heart disease suffer stronger impacts.
   • Low-income communities
     • Often live near highly polluted areas (industrial zones, highways) and have less access to healthcare.
   • Workers exposed outdoors
     • Street vendors, construction workers, traffic police, and public transport drivers breathe polluted air daily.

5. Business and industries contributing

   • Automotive & transport sector
     • Taxi fleets, freight trucks, logistics companies, and private transport businesses with old, high-emission vehicles.
   • Manufacturing & industrial plants
     • Cement, steel, chemical, and textile industries that release particulate matter and toxic gases.
   • Energy & fuel providers
     • PEMEX and local gas stations → fuel quality and distribution directly affect emission levels.

6. Plans, regulations, initiatives, created by private sector

   • Cemex / Ternium – decarbonization plans
     • reduces emissions via
       • cleaner production
   • Delivery & logistics companies (Uber, Rappi, DHL, FedEx)
     • implements
       • electric fleets / low-emission vehicles
