Main sources of carbon dioxide emissions
The largest source of greenhouse gas emissions from human activities in the United States is from burning fossil fuels for electricity, heat, and transportation. EPA tracks total U.S. emissions by publishing the Inventory of U.S. Greenhouse Gas Emissions and Sinks.
Hence, according to the United Nations Food and Agriculture Organization (FAO) livestock generate 18 percent of total greenhouse gas emissions as measured in CO2 equivalents — more than the entire transport sector, automobiles, trains, ships, and planes. …
The 20 countries that emitted the most carbon dioxide in 2018

Global Emissions by Economic Sector Electricity and Heat Production (25% of 2010 global greenhouse gas emissions): The burning of coal, natural gas, and oil for electricity and heat is the largest single source of global greenhouse gas emissions.
Here are the top five carbon-intensive sectors:
In 2019, China was the biggest emitter of fossil fuel carbon dioxide (CO2) emissions. With a share of almost 30 percent of the world’s total CO2 emissions that year, this was roughly twice the amount emitted by the second largest emitter the United States.
Energy consumption According to the Climate Data Explorer published by World Resources Institute, China, the European Union and the U.S. contributed to more than 50% of global greenhouse gas emissions. In 2016, China’s greenhouse gas emissions accounted for 26% of total global emissions.
Sources of emissions. When it comes to causes of emissions, the main reason China’s have been so high is because the country has been so heavily reliant on coal. Around 73% of China’s CO2 emissions, more than those from all European, African, and Latin American countries combined, come from this reliance.
China, along with 196 countries, agreed to help reduce rising global temperatures and set a goal temperature of 1.5 degrees celsius above pre-industrial temperatures. China has agreed to its NDC goal of reducing the CO2 intensity of its gross domestic product by 60% by 2030.
Carbon neutrality is achieved by calculating a carbon footprint and reducing it to zero through a combination of efficiency measures in-house and supporting external emission reduction projects.
To achieve carbon neutrality by 2060, China needs to follow the 1.5°C pathway and begin the effort today, with energy leading the way. Fossil-fuel-generated energy needs to be limited to 25% to 30% of total energy and about 20% in electricity generation by 2050.
Since 1978 China has established ten forest ecological projects, with a scheduled afforestation area of 120 million hectares — aimed mainly at protecting and improving the natural eco-environment and realizing the sustainable use of natural resources.
The water resources of China are affected by both severe water quantity shortages and severe water quality pollution. An increasing population and rapid economic growth as well as lax environmental oversight have increased water demand and pollution.
Since the initial passage of the framework Environmental Protection Law in 1979, China has passed many laws, regulations, and standards addressing environmental protection. The tax applies to specified air pollutants, not including carbon dioxide. …
China Makes Environmental Protection a Priority National leaders implemented regulations and strengthened enforcement of environmental policies. Environmental protection has also become common rhetoric in political campaigns, causing more and more Chinese people to consider how their activities impact the environment.
1.1. China upholds efforts for sustainable development even in Covid times. China’s rapid economic growth since 1978 has been fueled mainly by coal. Combined with poorly regulated impacts of industrial production, this led to severe environmental damage to air, land and water.
From the 1980s to the 1990s, China began to work on soil environmental research by starting the Modern conservation tillage research with the support of Australia. From 2000 to now, the problem of soil pollution in China has become increasingly serious.
According to a first-of-its-kind national survey, only 14.2% of Chinese said they were “very seriously concerned” about global warming and climate change. Not surprisingly, such concerns declined in areas economically dependent upon carbon-intensive industries.
The overall pollution in China fell further 10% between 2017 and 2018. Another study shows that China reduced PM2.5 by 47% between 2005 and 2015. Beijing is on track to drop out of the Top 200 most polluted cities by the end of 2019.
Over the past 20 years, the city has implemented air pollution reduction measures, including energy infrastructure optimization, coal-fired pollution control and vehicle emission controls. The report finds that, since 2013, air pollutants in Beijing have decreased by 25-83%, depending on the pollutant.
Consequently, air pollution in China predominantly consists of coal smoke, with suspended particulate matter (PM) and sulfur dioxide (SO2) as the principal air pollutants.
