China and the United States top the list of the largest CO2 emitters worldwide, according to an analysis based on data from the Global Carbon Atlas. These two nations are responsible for almost half of global emissions, driven primarily by fossil fuel use and industry. The fight against climate change falls largely on these giants, while other countries also face similar environmental challenges.
A recent report from the World Meteorological Organization (WMO) revealed that in 2020, the concentration of CO2 in the atmosphere reached historic levels, registering 413 parts per million (ppm), 149% above pre-industrial levels, they comment from the Xataka portal. Despite a temporary reduction in emissions during the pandemic, the trend has not subsided, underscoring the urgency of action against climate change.
Chinathe largest emitter of CO2 worldwide, contributes 31% of global emissionsreleasing more than 10,000 million metric tons of carbon dioxide in 2020. This high level of pollution is directly related to the intensive use of fossil fuels, mainly coal, which represents 55% of its energy matrix. Despite being one of the largest importers of oil, China has begun to adopt renewable energy to reduce its dependence on coal.
The United States is the second largest emitter, with 13.5% of global emissions, derived mainly from transportation and energy generation. The country, which is a major producer of crude oil, faces a significant challenge in reducing its dependence on motor vehicles. Despite its efforts in clean energy, transportation remains one of the main sources of pollution.
India and Russia: other large emitters
Indiathe third largest emitter of CO2, contributes to the 7.3% of global emissionswhile Russia, with 4.7%is placed in fourth place. In both cases, dependence on coal and natural gas is one of the main reasons for their emissions. In Russia, for example, coal remains central to its industry, contributing significantly to the CO2 emitted by the country.
As the most polluting nations face increasing pressure to reduce their emissions, global efforts to mitigate the impact of climate change remain crucial. With larger countries contributing disproportionately, the need to implement cleaner energy strategies has become high on the international agenda.
