What is Climate Change?
Climate change occurs when human activities release greenhouse gases, like carbon dioxide (CO2), into the atmosphere. These gases trap heat, causing the Earth's temperature to rise. This warming affects weather patterns, leads to melting ice, and raises sea levels, all of which disrupt natural systems and environments.

What proof exists that temperatures are rising?
Global temperatures have been steadily rising over the years, as shown by data from NASA, NOAA, and the Hadley Centre. These organizations track temperature records and consistently report that the past decade has been the warmest on record. For example, NASA's data reveals an increase of about 1.2°C since the late 1800s, while NOAA's records show that 19 of the 20 warmest years have occurred since 2001. This warming trend is evident from both surface and satellite measurements, highlighting a clear pattern of rising temperatures.

Where does CO2 come from?
The majority of carbon dioxide (CO2) emissions come from the burning of fossil fuels, such as coal, oil, and natural gas, used in energy production for electricity, transportation, and heating. Industrial processes, like cement manufacturing and steel production, also contribute significantly to CO2 emissions. Deforestation further exacerbates the problem by reducing the number of trees that can absorb CO2 from the atmosphere. Together, these sources account for the bulk of human-caused CO2 emissions, driving global warming and climate change.

What would happen with a reduction of machine hours?
Reducing machine hours would have several positive effects on the environment. With fewer operating hours, machinery would consume less fossil fuel, leading to a decrease in CO2 emissions and other pollutants like nitrogen oxides and particulate matter. This reduction in greenhouse gases would help slow down global warming and mitigate climate change. Additionally, decreased emissions could improve air quality, benefiting public health and reducing smog and respiratory issues. Overall, cutting machine hours can contribute to a cleaner, more sustainable environment by lowering carbon footprints and easing pressure on natural resources.

How does eco-friendly clothing brands reduce their carbon footprint?
Eco-friendly clothing brands reduce their CO2 emissions by using sustainable materials, such as organic cotton and recycled fibers, which require less energy and fewer resources to produce. They also adopt energy-efficient production methods and renewable energy sources to cut down on fossil fuel use. By employing low impact dyeing techniques and minimizing waste, these brands further decrease their carbon footprint. Additionally, they focus on durable, high-quality garments that last longer, reducing the need for frequent replacements and the associated emissions from manufacturing and transportation.

How can a clothing brand measure the amount of CO2 that they produce?
The average T-shirt requires 7kg (15.4lbs) of CO2. By using methods to process shirts such as knitting & weaving, wet treatment or confectioning yields the production of 10 kilowatt-hour (kwh)^4 of energy for each method. When breaking down the amount of energy and effort needed to produce clothing from various materials, we learn that:
- Conventional Cotton = 8.4kg (18.48lbs) CO2e
- Organic Cotton = 4.07kg (8.95lbs) CO2e
- Hemp = 3.0kg (6.60lbs) CO2e
- Bamboo = 2.04kg (4.49lbs) CO2e
As an example, if two shirts were getting produced; one made of conventional cotton and the other created from bamboo; we can assume that the conventional cotton shirt would require = 8.4kg (18.48lbs) CO2e. While a shirt made from bamboo would only require 2.04kg (4.49lbs) CO2e. Therefore, we can assume that purchasing a shirt made from bamboo rather than conventional cotton will prevent 6.36kg (13.99lbs) CO2e from being emitted into our atmosphere.

What can 1kg (2.2lbs) of CO2 power?
To drive a car one mile, it requires that 347grams (0.347kg) ((0.765lbs)) of CO2e be emitted into the atmosphere. This means that the energy needed to produce one shirt made from conventional cotton would be equivalent to the CO2e that a car would emit after driving a little over 24 miles.
