CO2 Emissions & Global Warming

CO2 Emissions & Global Warming

There is no doubt that global warming is one of the biggest challenges facing humanity, however correlation does not imply causation. Human activities have likely increased atmospheric carbon dioxide, which is a significant factor in global warming.

Carbon dioxide (CO2) plays an important role in climate change since it contributes significantly to air pollution. Due to carbon dioxide’s ability to trap radiation at the ground level, causing ground level ozone.

CO2 Emissions Tons Per Capita

According to WDI data analysis, Qatar has the highest CO2 emissions per capita due to two main reasons: Qatar is the largest LNG producer and Qatar has a relatively small population. In addition to being a developing country, Qatar exports the most LNG worldwide and has the third highest reserves of natural gas.

CO2 Emissions from Transport

The transportation sector generates the largest share of greenhouse gas emissions. Greenhouse gas emissions from transportation primarily come from burning fossil fuel for our cars, trucks, ships, trains, and planes. CO2 emissions from transport contain emissions from the combustion of fuel for all transport activity, regardless of the sector, except for international marine bunkers and international aviation. This includes domestic aviation, domestic navigation, road, rail and pipeline transport. The WDI dataset shows that Paraguay has the highest percentage of CO2 emissions. From 1997 to 2014, CO2 emissions in Paraguay from transport (%) fluctuated substantially, increasing to 93.1% in 2014.

CO2 Emissions from Manufacturing Industries and Construction

CO2 emissions from manufacturing industries and construction contains the emissions from combustion of fuels in industry. The IPCC Source/Sink Category 1 A 2 includes these emissions.

United Arab Emirates CO2 emissions from manufacturing industries (%) was at level of 36.9 % in 2014, down from 41.5 % previous year followed by Luxembourg, Gabon, and China.

Buildings and Construction is one of the key industries in the Middle East, the construction industry has achieved considerable progress in reducing its overall environmental impact over the past few years as a result of understanding its impact on the environment, innovation of its methods, processes, and sustainable resource use.

CO2 Emissions (KT)

CO2 emissions of China increased from 2,173,360 million tones in 1990 to 11,680.4 million tons in 2020 growing at an average annual rate of 5.44%. By 2019, CO2 emission for China has reached 10,707,220 million tons.

CO2 emissions (metric ton per capita) is good metric for measuring relative improvements between countries with different population sizes, however absolute CO2 emissions (kt) is the most important metric when considering which countries have the most impact on global emissions.


In most cases, greenhouse gases like carbon dioxide are responsible for causing climate change. As a result of factories and transportation emitting large amounts of CO2, the planet becomes warmer and more polluted, causing global warming problems.

Industries need to reduce their reliance on fossil fuels, recycle components, and adopt more environmentally friendly design practices, as well as insist on a better value chain-wide approach.

Digital revolution is changing the world and all manufacturers can take advantage of it to make things better.  By 2030, digital technologies could have a significant impact on reducing global carbon emissions, through solutions in energy, manufacturing, agriculture, building construction, services, transportation, and traffic management.

Also, sustainability needs to be a central component of business models. It is imperative that every company implements a low-carbon business model as part of its long-term strategy.
