Now, Sustainable Leather Manufacturing includes carbon offsetting. This helps along with cutting down direct emissions. For instance, DANI, a top leather company, has a detailed plan:
- Offsetting direct (scope 1) and indirect (scope 2) emissions
- Preparing an inventory of impacts using ISO 14064-1 standards
- Verifying compliance through independent certification
- Participating in certified projects in developing countries
DANI says they’re carbon neutral, beating the 2050 European goal. This shows the industry what’s possible. Other leather makers can also go green by planting trees or backing clean energy.
Leather from cow skin makes about 17.0 kg of CO2e per square meter. But, when we add farm emissions, it’s 110.0 kg CO2e/m2. These numbers show how vital carbon offsetting is for making leather better.
The leather industry faces competition from new materials. But, by using carbon offsetting, they can stay ahead and be kinder to the planet.
Life Cycle Assessment of Leather Products
I’ve been looking into Life Cycle Assessment (LCA) of leather products. It’s really interesting. LCA helps us see how leather goods affect the environment from start to finish. In the last six years, 30 out of 39 studies on this topic were published.
Cradle-to-grave analysis of leather goods
The LCA process has four main steps. These are defining goals and scope, analyzing inventory, assessing impacts, and interpreting results. This detailed method helps us understand and improve the leather industry’s environmental effects.
It looks at things like climate change, ozone depletion, and how harmful substances are to humans. It also considers how much dust is released into the air.
Comparing carbon footprints of different leather types
When we compare carbon footprints, bovine leather has the biggest impact. It uses a lot of carbon, is toxic, and uses a lot of water. PU leather is another option, but it also has environmental costs because it’s made from non-renewable materials.
But, mycelium leather is the most eco-friendly. It has the lowest scores in all environmental areas.
