WHO issues new, lower Global Air Quality Guidelines for classical pollutants

Green Car Congress

New WHO has issued new Global Air Quality Guidelines (AQGs) that reduce levels of key air pollutants, some of which also contribute to climate change. Since WHO’s last 2005 global update, there has been a marked increase of evidence that shows how air pollution affects different aspects of health. Source: WHO. nitrogen dioxide (NO?)

HEI study in Europe finds evidence of health effects at lower levels of air pollution

Green Car Congress

A major new Health Effects Institute (HEI) report presents a study examining associations between exposures to relatively low levels of air pollution and several health outcomes among participants in 22 European cohorts. Initial results were published in 2019 and Phase 2 results are under review. particle composition.

NUS researcher links air pollution to increased residential electricity demand

Green Car Congress

The results of the study were published in the Journal of the Association of Environmental and Resource Economists. The reasons were two-fold: (i) increased air pollution led to households staying indoors more to mitigate the pollution impact; and (ii) PM 2.5 pollution ranges between 20 and 200 ? —Prof Salvo.

ICL briefing paper estimates that 52% of all small particle pollution from road transport comes from tires and brakes

Green Car Congress

A new briefing paper from Imperial College London estimates that in 2021, 52% of all small particle pollution from road transport came from tires and brakes. Tire wear particles pollute the environment, the air we breathe, the water run-off from roads and has compounding effects on waterways and agriculture.

NYU review study suggests potential for gauging health risks of air pollution on individual level

Green Car Congress

In the past, pollution measurement has been relatively crude in terms of compositional, spatial, and temporal resolution. There have been significant improvements in the ability to conduct granular measurement of air pollutants, and this has enabled more awareness and more focused local policy actions, as addressed below. Globally, 4.2

CARB approves updated “At-Berth” regulation, expanding efforts to cut pollution from ships in California ports

Green Car Congress

The California Air Resources Board approved a new regulation designed to reduce pollution further from ocean-going vessels while docked at California’s busiest ports. Proposed projects will require extensive community review as well as CARB approval. An example would be purchasing zero-emission heavy-duty trucks for port use.
