Generating Power

• Producing electricity and heat from fossil fuels accounts for a large share of global greenhouse gases emissions.
• Slightly over 25% of electricity worldwide is generated by wind, solar, and other renewables.

• Renewables emit little to no greenhouse gases or air pollutants.

Using Transportation

• Most automobiles, trucks, ships, and airplanes rely on fossil fuels, making transportation a major source of greenhouse gas emissions, particularly carbon dioxide.

• Road vehicles are the largest contributors due to burning petroleum-based fuels in internal combustion engines.
• Emissions from maritime and air transport are steadily increasing.
• Overall, transportation is responsible for nearly 25% of global carbon dioxide emissions from energy use.

Cutting Down Forests

• Cutting down forests for agriculture, livestock grazing, or other human activities releases store carbon into the atmosphere.
• About 12 million hectares of forest are lost each year, showing the scale of the practice.
• Destroying forests reduces the Earth’s natural ability to absorb carbon dioxide.
• Deforestation, combined with agriculture and land-use changes, drives roughly 25% of global greenhouse gas emissions.

Manufacturing Goods

• The manufacturing sector is a major global source of greenhouse gas emissions, largely due to its reliance on fossil fuels like coal, oil, and gas.

• Energy from these fossil fuels powers the production of materials such as cement, iron, steel, electronics, plastics, and textiles.

• Mining, industrial processes, and construction activities also release significant greenhouse gases.

• Some materials, like plastics, involve chemicals derived from fossil fuels.

Consuming Too Much

• Household energy use, transportation choices, food habits, and waste generation all contribute to greenhouse gas emissions.
• Consumption of products such as clothing, electronics, and plastics further adds to emissions.
• Private households account for a significant proportion of global greenhouse gas emissions.
• Individual lifestyles have a considerable impact, with the wealthiest responsible for the largest share; globally, the top 1% of income earners produce more emissions than the poorest 50%.

Producing Food

Food production is a major driver of climate change, generating carbon dioxide, methane, and other greenhouse gases through:◦ Deforestation and land clearing for agriculture and livestock grazing ◦ Methane emissions from digestion in cattle and sheep ◦ Fertilizer and manure use in crop cultivation ◦ Energy consumption for farming equipment or fishing boats, often powered by fossil fuels ◦ Food packaging and distribution.
