NAU team finds US greenhouse gas emissions decline during COVID lockdown 3x greater than previously reported

Posted by Heather Tate on May 3, 2021

Scientists build reliable, real-time emissions estimate system to inform, correct public policy as nation takes on new reduction targets

CO2 emissions illustrationThe COVID-19 pandemic has altered energy use and greenhouse gas (GHG) emissions globally and continues to influence emissions as the response to COVID-19 evolves. Reliable data that can provide a real-time update of emissions has been difficult to acquire… Read more

NAU study indicates that U.S. cities underestimate their greenhouse gas emissions by nearly 20 percent on average

Posted by Heather Tate on February 2, 2021

City emissions graphCities have become critical players in reducing the greenhouse gas (GHG) emissions that are causing global climate change. Urban areas produce almost 70 percent of those emissions, and city governments are proposing a variety of policy actions aimed at reducing them. Many cities also produce inventories that detail their greenhouse gas emissions.

Now, professor Kevin Gurney of Northern Arizona University’s School of Informatics, Computing, and Cyber Systems and… Read more

NAU atmospheric scientist maps CO2 emissions for entire U.S. landscape to help improve environmental policymaking

Posted by Heather Tate on October 5, 2020

Vulcan Project mapWith intense wildfires in the western U.S. and frequent, intense hurricanes in the Gulf of Mexico, the nation is again affected by extreme weather-related events resulting from climate change. In response, cities, states and regions across the country are developing policies to reduce their emissions of greenhouse gases, chiefly carbon dioxide (CO2). Even though many state and local governments are committed to these goals, however, the emissions data they… Read more

NAU research team sees major shift in relationship between state-by-state traffic and COVID-19 cases, offering insights into outcomes of lockdown policies

Posted by Heather Tate on June 9, 2020

The upper left panel shows that during the month of March 2020, the decline in traffic across the US coincided with the rise in COVID-19 cases. The country responded in a uniform fashion. The lower panel shows how that correlation in traffic-COVID-19 broke down with traffic rising in most states but COVID-19 cases rising in… Read more

NAU’s Vulcan Project fossil fuel emissions show best match to carbon-14 measurements

Posted by Heather Tate on June 2, 2020

Vulcan Project Infographic
Study findings take a dramatic step towards a greenhouse gas information system that can fundamentally change the way cities, states and the nation tackle the climate change problem

Results from Northern Arizona University’s Vulcan Project estimating carbon dioxide (CO2) emissions from fossil fuel combustion for the entire U.S. show very close agreement to a new atmospheric-based approach for estimating these same emissions, as reported in a paper… Read more
