Elsevier established a free COVID-19 resource center in January 2020, offering information in English and Mandarin. The center is hosted on Elsevier Connect, and the company grants permission for free access to its research in PubMed Central and other repositories. A study explores the impact of the COVID-19 pandemic on environmental pollution, noting that lockdowns reduced pollution by up to 30% in affected areas. The study uses data from NASA and ESA to show that NO2 emissions decreased significantly in cities like Wuhan, Spain, Italy, and the USA. Lockdowns reduced mobility by up to 90%, with transport and industrial sectors heavily affected. The pandemic caused a sharp decline in global oil demand and prices. While the pandemic has had severe health and economic impacts, it has also led to reduced pollution. NO2, a harmful pollutant mainly from fossil fuel combustion, saw significant reductions due to decreased traffic. The study concludes that the pandemic, though a global health crisis, has acted as a "blessing in disguise," highlighting the need for long-term pollution reduction strategies.Elsevier established a free COVID-19 resource center in January 2020, offering information in English and Mandarin.
