COVID-19 provided a convenient way of studying the dynamics of anthropogenic emissions of carbon dioxide

In the case of an extension of the isolation chambers States that it was introduced, until mid-summer, the planet can wait for a total reduction of anthropogenic emissions of carbon dioxide by 4.2 percent. If the restrictions will last until the end of the year, emissions will decrease to 7.5%. The authors of a study published in the journal Nature Climate Change, noted that the pandemic has provided a unique environment to study the dynamics of anthropogenic emissions: spring 2020 was a convenient period of time to better understand the responsibility of countries and industries for emissions of CO2 into the atmosphere.

The economic crises of the last decades was accompanied by a reduction in emissions of carbon dioxide into the atmosphere. However, the pandemic COVID-19 differs from them in isolation in some countries, which leads to the widespread decline in demand for energy and transport, as well as the restructuring of key sectors of the economy.

Unfortunately, to quantify the impact of the pandemic on the dynamics of the emission of CO2 is quite difficult: events are moving quickly, and the environmental monitoring system is not adapted to the publication of all indicators in real-time. As a rule, at the disposal of scientists are critical of the total annual emissions of carbon dioxide, and sometimes they are published months later. Meanwhile, it is important to find a way to estimate the reduction in emissions that occurs every day, because by the end of the year, the pooled data will make it impossible.

Scientists led by Corinne Le Coeur (Corinne Le Quéré) from the University of East Anglia conducted a quantitative analysis of the dynamics of anthropogenic emissions of carbon dioxide from January to April of 2020. The study included 69 countries in Europe and other world regions, 50 US States and 30 provinces of China. In these areas, home to 85 percent of the population of the Earth and is 97 per cent of global emissions of CO2.

First, the authors of the study established four levels of restrictions imposed by the States of zero corresponded to the absence of restrictions; the first level includes the limits for small groups of people who are carriers of the infection; on the second level of restrictions relating to entire cities and regions, affecting up to 50 percent of the population; on the fourth limit was nationwide.
