CLEAN : Deserted New York leads to "sharp reduction" in air pollution, says scientist

The video discusses the impact of reduced traffic on pollution levels, particularly in New York, where a significant drop in vehicle numbers led to decreased emissions. It highlights New York's unique pollution sources, including traffic and building boilers. The video also examines pollution trends in China, noting increased NO2 levels. Despite reductions, CO2 emissions remain substantial. The discussion extends to economic and social implications, emphasizing the need for policies that maintain low emissions without harming the economy.

What was the primary reason for the reduction in pollutants during Saint Patrick's weekend in New York?

• A significant drop in the number of vehicles on the road

• A change in weather patterns

• A decrease in industrial activity

• An increase in public transportation usage

Apart from traffic emissions, what is a major source of pollution in New York during winter?

• Industrial factories

• Construction sites

• Public transportation systems

• Boilers in apartment buildings

What is the relationship between NO2 and CO2 emissions mentioned in the video?

• NO2 emissions are only from natural sources

• CO2 emissions are higher than NO2 emissions

• NO2 emissions are unrelated to CO2 emissions

• Every source of NO2 is also a source of CO2

Despite a reduction in emissions, why might we not notice a significant change in CO2 levels?

• CO2 levels are naturally low

• The reduction is too small compared to the total emissions

• CO2 is not a major pollutant

• CO2 levels are not measured accurately

What is a potential consequence of low emissions policies on the economy, as discussed in the video?

• Increased job opportunities

• No noticeable impact

• Significant job losses

• Improved social safety nets
