Where sustainability science meets AI
Sustech Solutions helps manufacturers, technology companies and research teams measure environmental impact, plan credible routes to net zero, and build AI that gets the science right.
That was the finding of Izhar's Nature Communications paper. The same rigour goes into every client project: published methods, transparent data and numbers that stand up to scrutiny.

Pick a product, then click a stage. These patterns come from published life cycle studies, including our own research.
of global CO₂ emissions come from cement production.
Chatham House, 2018A company's supply chain emissions are, on average, 11.4 times its own operational emissions.
CDP, 2021lower life cycle emissions for a battery electric car sold in Europe today than a petrol car.
ICCT, 2025Science you can stand behind
Every engagement is led by a PhD-qualified specialist and grounded in published, peer-reviewed methods, so the numbers stand up to scrutiny from customers, investors and regulators.
Discuss a project →Clear steps from first call to final report
Small, focused projects or longer programmes. Either way, you know what happens next and why.
Scope
Agree the question, the system boundary and what a useful answer looks like.
Data
Collect and check the data, from supplier records to plant and lab figures.
Model
Build the assessment or evaluation with recognised, peer-reviewed methods.
Review
Test the results for sensitivity and gaps before anyone relies on them.
Report
Plain findings your team, customers and regulators can act on.
Research behind the advice
Peer-reviewed work on life cycle assessment, industrial decarbonisation and resource flows. The methods we publish are the methods we use.
1.4 gigatons of annual greenhouse gas emissions can be avoided using clinker substitution
Quantified the global emissions saved by replacing clinker with alternative materials.

Led by Dr Izhar Shah
Izhar founded Sustech Solutions in 2024 after three years as a subject matter expert in engineering sustainability at Jaguar Land Rover, where he worked on life cycle assessment and net-zero technology for electric drive programmes.
Before that he was a post-doctoral researcher at Imperial College London, working on industrial decarbonisation of cement and steel. His Nature Communications paper showed that clinker substitution could avoid 1.4 gigatons of greenhouse gas emissions a year.
He holds a PhD in Environmental Engineering, has supervised MSc and PhD students, and has taught at UCL, Warwick and Reading.
