Greenhouse Gas Emissions
Carbon dioxide, methane, and other greenhouse gases trap heat in Earth's atmosphere, causing global warming.
Key Fact
CO₂ levels are 50% higher than pre-industrial levels and continue to rise.
Transportation
Cars, trucks, ships, and planes burn fossil fuels, releasing significant amounts of greenhouse gases.
Key Fact
Transportation accounts for approximately 14% of global greenhouse gas emissions.
Electricity Production
Burning fossil fuels like coal, oil, and natural gas to generate electricity releases carbon dioxide.
Key Fact
Electricity production generates about 25% of global greenhouse gas emissions.
Deforestation
Cutting down forests reduces the planet's ability to absorb CO₂ and releases stored carbon.
Key Fact
About 12 million hectares of forest are lost each year, equivalent to 30 football fields per minute.
Agriculture
Livestock produce methane, and fertilizers release nitrous oxide—both powerful greenhouse gases.
Key Fact
Agriculture contributes approximately 24% of global greenhouse gas emissions.
Buildings & Industry
Energy used for heating, cooling, and manufacturing processes contributes to emissions.
Key Fact
Buildings account for about 6% of global greenhouse gas emissions.

Fossil Fuel Extraction
Extracting oil, coal, and natural gas for energy production releases methane and causes land degradation.
Key Fact
Fossil fuel extraction sites are among the top sources of methane emissions worldwide.

Waste Decomposition
Organic waste in landfills decomposes anaerobically, emitting large quantities of methane gas.
Key Fact
Waste contributes over 3% of all greenhouse gas emissions globally.

Air Travel
Airplanes emit CO₂ and other pollutants directly into the upper atmosphere, amplifying their warming effect.
Key Fact
Air travel accounts for 2.5% of global CO₂ emissions—and rising.

Cement Production
Cement manufacturing releases CO₂ through chemical reactions and fuel combustion.
Key Fact
Cement is responsible for about 8% of global carbon dioxide emissions.

Fast Fashion
The fashion industry emits greenhouse gases through textile production, dyeing, and global transportation.
Key Fact
Fast fashion produces 10% of all global carbon emissions—more than international flights and shipping combined.
