Which sector is the largest emission of global co2?

Energy consumption is by far the biggest source of human-caused greenhouse gas emissions, responsible for a whopping 76% (37.2 GtCO2e) worldwide. The energy sector includes transportation, electricity and heat, buildings, manufacturing and construction, fugitive emissions and other fuel combustion.

What sector produces the most co2?

Here are the top five carbon-intensive sectors:

• Energy Production. The burning of fossil fuels for energy production is single-handedly the biggest source of carbon dioxide emissions.
• Agriculture, Forestry and Other Land Use (AFOLU)
• Industry.
• Transport.
• Residential, Commercial and Institutional Sectors.

Which sectors is the single largest co2 contributor globally?

Here we see that electricity and heat production are the largest contributor to global emissions. This is followed by transport, manufacturing and construction (largely cement and similar materials), and agriculture.

What industry contributes most to global warming?

Top 5 Sectors Contributing to Global Warming

• Electricity Generation and Heat Production. The first sector on our list is electricity generation and heat production, which accounts for approximately 28% of the world’s greenhouse gas emissions.
• Transportation.
• Industry.
• Commercial and Residential Emissions.
• Agriculture.

What gas is most responsible for global warming?

Carbon dioxide
Carbon dioxide (CO2) is the primary greenhouse gas emitted through human activities. In 2019, CO2 accounted for about 80 percent of all U.S. greenhouse gas emissions from human activities.

What is the #1 contributor to global warming?

Indeed, carbon dioxide, a byproduct of fossil fuel combustion, is the principal greenhouse gas contributing to global warming. However, other greenhouse gases including methane, nitrous oxide, and a number of industrial-process gases also are important contributors to climate change.

What company is the world’s biggest polluter?

Global emitters (1965 to 2017)

Rank	Company	Country
1	Saudi Aramco	Saudi Arabia
2	Chevron Corporation	United States
3	Gazprom	Russia
4	ExxonMobil	United States
