It is difficult to predict with certainty, but currently, China has the highest CO2 emissions globally. However, efforts to reduce emissions are ongoing worldwide, so the ranking may change by 2025.
Solar power itself does not produce CO2 emissions during electricity generation. However, CO2 may be indirectly produced during the manufacturing, transportation, and installation of solar panels, as well as through maintenance activities. Overall, when considering the entire life cycle, solar power generates significantly less CO2 compared to fossil fuel-based electricity sources.
Activities that do not increase carbon dioxide levels in the atmosphere include processes such as photosynthesis, where plants absorb CO2 and release oxygen, and the use of renewable energy sources like wind, solar, and hydroelectric power, which do not emit CO2 during electricity generation. Additionally, practices like reforestation and afforestation can help sequester carbon, thereby reducing atmospheric CO2 levels. Organic farming methods that enhance soil health can also contribute to lower carbon emissions.
Carbon enters the atmosphere primarily through the combustion of fossil fuels, such as coal, oil, and natural gas, which releases carbon dioxide (CO2) as a byproduct. Additionally, deforestation contributes to carbon emissions, as trees that absorb CO2 are removed, leading to increased atmospheric carbon levels. Lastly, natural processes like volcanic eruptions and respiration from living organisms also release carbon into the atmosphere.
CO2 in the atmosphere exists throughout different layers, but it is mainly transported to the upper atmosphere through atmospheric circulation and mixing processes. Some CO2 molecules can also be carried to the upper atmosphere by volcanic eruptions or in the form of methane, which can be oxidized into CO2 at higher altitudes.
When bromothymol blue is exposed to CO2, it undergoes a color change. In the presence of CO2, bromothymol blue turns from blue to yellow due to the formation of carbonic acid. This color change can be used as an indicator for the presence of carbon dioxide.
Qatar has the highest CO2 emissions per capita in the world. This is due to its heavy reliance on oil and gas production as well as its small population size, leading to high emissions per person.
The energy sector has the highest CO2 emissions from fossil fuel combustion, as it includes activities such as the burning of coal, oil, and natural gas for electricity generation and heating. This sector is a major contributor to greenhouse gas emissions globally.
They differ from country to country in many ways. Depends really on what you are actually looking for. See links below to get more info on global CO2 emissions.
This is the total emissions of carbon (from CO2 and CH4), expressed in tons, for a country in one year.

Reduce its need for fosil fuels to generate its energy and power its tranportation system.
CO2 and methane from our bodies.
The average CO2 emissions per car per year is around 4.6 metric tons.
Power plants can purchase scrubbers to remove some CO2.
China is the largest emitter of CO2. It nearly doubles the next highest, the US.
1% of the worldds emissions
The average carbon footprint per household per year in the US is around 48 metric tons of CO2 equivalent. This includes emissions from activities such as electricity consumption, transportation, and waste production.
