Harvard/Nanjing study: China’s war on PM2.5 pollution is causing more severe ozone pollution

Green Car Congress

Cities restricted the number of cars on the road, coal-fired power plants reduced emissions or were shuttered and replaced with natural gas. pollution is falling, harmful ground-level ozone pollution is on the rise, especially in large cities. There was so much particulate matter in Chinese cities that it stunted the ozone production.

coal, oil, natural gas, and biomass). Among the findings: Summer surface ozone (O 3 ) decreases in most locations due to widespread reductions of traffic NO x emissions. Summer fine particulate matter (PM 2.5 ) increases on average and largest in areas with increased coal-fired power generation demands. Seasons and times of day.

Low-lying and other vulnerable countries calling for fast action on non-CO2 global warming pollutants

Green Car Congress

Among the non-CO 2 pollutants are hydrofluorocarbons (HFCs), methane, tropospheric ozone, and black carbon soot. Technology is already available to reduce these climate-forcing agents, and doing so would produce strong collateral benefits. Reducing tropospheric ozone can improve public health as well as agricultural productivity.

NASA satellite images highlight US air quality improvement with reduction of NO2

Green Car Congress

After ten years in orbit, the Ozone Monitoring Instrument (OMI) on NASA’s Aura satellite has been in orbit sufficiently long to show that people in major US cities are breathing less nitrogen dioxide. The gas is produced primarily during the combustion of gasoline in vehicle engines and coal in power plants.

National Academies Report Examines Hidden Cost of Energy Production and Use in US; Estimates $120B in 2005

Green Car Congress

A new report from the National Research Council examines and, when possible, estimates, “hidden” costs of energy production and use—such as the damage air pollution imposes on human health—that are not reflected in market prices of coal, oil, other energy sources, or the electricity and gasoline produced from them.

60% of ground-level ozone (O 3 ) precursors, 6% of fine particulate matter (PM 2.5 ), and 22% of greenhouse gases (GHGs) emitted. emissions owing to reduced coal mining activity caused by excess electricity generation in biorefineries which is sold to the electrical grid and assumed to offset electricity produced elsewhere.

IPCC: GHG emissions accelerating despite mitigation efforts; major institutional and technological change required to keep the heat down

Green Car Congress

Increased use of coal relative to other energy sources has reversed the long?standing Commercially available liquid and gaseous biofuels already provide co?benefits Between 2000 and 2010, both drivers outpaced emission reductions from improvements in energy intensity. carbon sources constitute longer term options.
