Carbon dioxide (CO2) emissions from the use of fossil fuels and the production of cement are the main driving force of climate change. Carbon Monitor is an international initiative providing for the first time regularly updated, science-based estimates of daily CO2 emissions. The data reveal the drop and re-growth of emissions during the COVID-19 pandemics.
