Greenhouse gas emissions don't just come from airplanes, factories and coal power stations. Our environmental footprint is spread across a huge range of everyday goods, from the videos we watch online to the water we drink.

The fashion industry is responsible for about 10% of global greenhouse emissions, according to the United Nations Framework Convention on Climate Change.

It consumes more energy than aviation and shipping industries combined. Most of those emissions come from its long supply chains and energy-intensive production -- especially the dyeing and finishing process.

Some glass furnaces are never turned off, operating at temperatures of up to 2,800 degrees Fahrenheit and emitting greenhouse gases including carbon dioxide, carbon monoxide, nitrogen oxides and sulfur oxides. Because a glass bottle weighs more than aluminum or plastic alternatives, it can produce greater transport emissions.

One study by researchers at the University of Manchester, UK, concluded that glass containers have a bigger carbon footprint than plastic or aluminum. But if a glass bottle is recycled enough times, it can have a smaller footprint than a plastic bottle.

Humans consume more calories from rice than any other food. But rice is grown by keeping paddy fields immersed in water, and microorganisms in the wet soil produce greenhouse gases.

Rice farming accounts for 1-2% of manmade greenhouse gas emissions. Slash-and-burn deforestation to clear land for rice farming also releases CO2.
