Carbon Trust endorses Braskem’s carbon-negative claims for bio-based plastic

Brazilian chemicals company Braskem, producers of I’m green – a bio-based polyethylene made from sugarcane – has had its negative carbon footprint credentials strengthened thanks to an independent review by the Carbon Trust. 
In a new report comparing I’m green with fossil-based equivalents, the Carbon Trust has endorsed the methodology used by Braskem to support claims that for every tonne of I’m green produced, the equivalent of around 3 tonnes of CO2 are locked away by the sugarcane, which provides the main raw material for its manufacture. This means Braskem’s bio-based plastic is effectively carbon-negative. 
Capturing CO2 during its lifecycle, I’m green avoids emissions related to the production of fossil fuel feedstock, thereby providing a net saving of the equivalent of around 5 tonnes of CO2¹ by the end of the plastic manufacturing process.
I’m green is 100% recyclable plastic currently being used in a range of applications from food packaging to personal care products, as well as more durable goods such as chairs and vases. 
Brand owners are increasingly responding to climate change by reducing their carbon footprint, which requires investment in more efficient processes and using innovative, renewable materials. Braskem’s I’m green is made from a renewable feedstock and can make a significant contribution to reduce carbon emissions.
John Newton, Associated Director at the Carbon Trust, said, “To address climate change we will need innovative materials that are radically lower in emissions compared to what is commonly used today. Products like I’m green, which help lock away carbon emissions in their production, can be a real part of the solution.”
Marco Jansen, Commercial Director Renewable Chemicals at Braskem, said, “We’re delighted that credible association Carbon Trust further validates our calculations of I’m green’s carbon footprint. Our customers know I’m green polyethylene is a smart and sustainable way to reduce a product’s carbon footprint and we hope more brands will use it as a renewable solution in the future.”
