Carbon Footprint Study of Mud Jeans 28 October, 2015
Introduction
What is an Embodied Carbon Footprint?
All products have an embodied carbon footprint. It results from the emissions of fossil fuels
burned through a product’s life cycle
The Carbon Cycle
Natural Cycle: Carbon is exchanged among the oceans, atmosphere, and ecosystem.
This cycle has been a closed, balanced system for hundreds of thousands of years.
Greenhouse Effect:
The Carbon Cycle is present in the atmosphere as carbon dioxide and methane. These
two primary greenhouse gases uniquely allow light to pass while capturing infrared energy;
directly impacting Earth’s atmospheric energy and temperatures.
Man-Made Greenhouse Contributions:
Burning fossil fuels release hydrocarbons which have been outside the natural carbon
cycle for millions of years. These emissions have increased atmospheric CO2 by 40%,
changing the chemistry and raising the total atmospheric energy and contributing to
climate change. Though unintended, our individual actions, business operations, and the
supply chain our products rely on are contributing to these impacts.
The Role of Carbon Offsetting:
Though we are not in control of all of our greenhouse gas emissions, we recognize our
Responsibility for them. Offsetting your emissions and being carbon neutral is about
restoring what our actions disturbed. It means cleaning up after ourselves and working to
leave our ecosystem as we found it for future generations. It is a statement of
responsibility and about what sort of world we wish to create.
Every 1 ounce CO2e
is equal to over 960
cubic inches of
Atmospheric
greenhouse gas.
This Carbon Footprint Study
This good-faith study draws from international sources in addition to information provided.
Report Terminology
CO2e: Carbon Dioxide Equivalent is a standard for expressing the impact of greenhouse
gas emissions in terms of the amount of CO2 that would have the same impact.
