Carbon Footprint Initiative

Prepare for a carbon-constrained world with IHS Chemical Carbon Footprint Initiative (formerly SRI Consulting Carbon Footprint Initiative). Clients may subscribe to our online emissions database covering nearly 360 chemical processes, as well as choose from our individual reports that offer deeper, product-specific analysis of emissions.

Today more than ever, engineers, technology managers and strategic planners need to know the level of greenhouse gas emissions of commercial and competitive technologies. Established in 2006, IHS Chemical Carbon Footprint Initiative is a service designed to help firms stay abreast of and comply with carbon emissions regulations. Based on the in-depth, independent technical and economic evaluations by the IHS Chemical Process Economics Program (PEP), the program provides a rigorous and systematic methodology for calculating and comparing carbon footprints of critical chemical processes. Coverage includes all of the primary petrochemicals and their process chains plus key bio-processes.

Clients may subscribe to the IHS Chemical Carbon Footprint Yearbook (formerly SRI Consulting Carbon Footprint Yearbook)– an online database containing carbon footprints for 359 chemical processes. A web-based calculation tool allows for customization by fuel type and geographic location. For products with appreciable by-products, multiple options exist for determining emissions output. The Yearbook includes one year of access to the online calculation tool.

Clients may also purchase the IHS Chemical Carbon Footprint Reports, which provide additional product-specific analysis of emissions, from polymers to biofuels. The reports also investigate regulatory matters, such as the potential tax disadvantages of Europe’s proposed biofuel certification requirements. For clients needing more customized analysis, IHS Chemical consultants can provide private research tailored to product, process, well-to-product and benchmarking considerations.

Whether you are comparing competing technologies, seeking to reduce current emissions or selecting a future project site, IHS Chemical Carbon Footprint Initiative is your best source of carbon emissions information.

Polypropylene's Carbon Footprint: Diverse, with Major Sensitivities

This study presents a cradle-to-gate carbon footprint of polypropylene (PP) from all its primary manufacturing routes as well as for biopolypropylene, which does not yet exist commercially (but is technically feasible).

PET's Carbon Footprint: To Recycle or Not To Recycle

Recycling programs using curbside collection typically displace less than 50% of new polyethylene terephthalate (PET). Community programs with plastic bottle take-back, mandated separate collection, or deposits on bottles tend to report much higher displacement rates. For regions that already have a recycling infrastructure, the aim should be to boost recycled PET (rPET) displacement of virgin PET (vPET) significantly above 50%. For countries with adequate space and little recycling infrastructure, disposing of bottles in landfill generates a lower carbon footprint than recycling or incineration. This report is an independent evaluation of the carbon footprint of PET bottles with an analysis of secondary packaging from cradle to grave and from production of raw materials through to disposal.

Polyethylene's Carbon Footprint: Global Variations and Comparisons

For years, polyethylene has been under public pressure. Laws have been enacted to discourage and even ban its use in numerous cities and countries around the globe. This report takes a detailed, objective look at this issue and its complications. This report provides a fast, easy, inexpensive way for those in the polyethylene chain to benchmark themselves — by ethylene feedstock, by region, by grade (HD, LD and LLD) and by eight different polymerization processes.

Carbon Certification of Biofuels

Carbon certification could cause nearly half of biodiesel capacity and half of bioethanol capacity in Europe to lose its tax-advantaged status

Carbon Footprint of Biofuels & Petrofuels

Our new Carbon Footprint of Biofuels & Petrofuels report combines technology information derived from SRIC's Process Economics Program with land use data to provide the first in-depth technical comparison of lifecycle CO2 emissions to account for alternative land use options. (Read More)
