How Engineers Can Help Protect Earth From Worsening Climate Change

Cars That Think

Fortunately, we still have a narrow window of opportunity to alter the Earth’s climate path, and I believe we can do it. Climate change is a global societal crisis that is causing devastating consequences. To create a sustainable environment, we need to contain air pollution.

UMD-led study finds China’s SO2 emissions down 75% since 2007, India’s up 50%; India may now be the top SO2 emitter

Green Car Congress

Although China and India remain the world’s largest consumers of coal, a new University of Maryland-led study found that China’s sulfur dioxide emissions fell by 75% since 2007, while India’s emissions increased by 50%. Sulfur dioxide is an air pollutant that causes acid rain, haze and many health-related problems.

U Toronto studies find traffic emissions spread farther than thought; 25% of cars causing 90% of pollution

Green Car Congress

A trio of recently published studies from a team of University of Toronto engineers has found that air pollution could be spreading up to three times farther than thought, contributing to varying levels of air quality across cities. We used to think that living near a major road meant that you lived near a lot of air pollution.

Black carbon is a much larger cause of climate change than previously assessed; about twice previous estimates, and 2/3 the effect of CO2

Schematic overview of the primary black-carbon emission sources and the processes that control. the distribution of black carbon in the atmosphere and determine its role in the climate system. Accounting for all of the ways black carbon can affect climate, it is believed to have a warming effect of about 1.1 Source: Bond et al.

Are Electric Cars Really Helping the Environment?

The Truth About Cars

The research, published in the Science of the Total Environment journal, presents the first real-world data linking EVs to reductions in air pollution and respiratory issues. Furthermore, the study showed a modest decrease in NO2 levels, a pollutant closely linked to traffic emissions.

Perspective: The Role of Offsets in Climate Change Legislation

Green Car Congress

An offset is a measurable reduction, avoidance, or sequestration of GHG emissions from a source not covered by an emission reduction program. In this way, offsets would complement the more traditional emissions trading that can occur between two covered sources. what would have happened anyway).

WHO: 9 out of 10 people worldwide breathe polluted air; 7M deaths per year

Green Car Congress

New data from the World Health Organization (WHO) shows that 9 out of 10 people breathe air containing high levels of pollutants. Updated estimations reveal a death toll of 7 million people every year caused by ambient (outdoor) and household air pollution. Ambient air pollution alone caused some 4.2 g/m 3 (for PM 10 ) and 10 ?g/m
