I work in sustainability, circular economy, and ESG, mostly the practical end of it, where you're actually trying to get something built or fixed rather than just written about.

Before any of this, I worked in India's development sector, my first contact with learning that sustainability plans are only as good as whether they survive contact with reality. That's stayed with me ever since. I've since worked as an ESG and sustainability consultant, and I currently lead environmental and sustainability work at J+S Subsea, where a lot of my time goes into things like carbon reduction strategy and Legacy Locker, a project I've helped build that refurbishes and reuses subsea equipment instead of scrapping it.
I was named Rising Star at the Subsea Expo Awards 2024, and won the Young Professional Award at Decarb Scotland 2025, nice recognition, but the part I care more about is whether the work actually reduces waste or emissions in a way you can point to.
Outside work: coffee, long walks with no real destination, and a strong bias toward being somewhere I've never been before. Some of my best ideas have shown up on a trail.
Always happy to talk sustainability strategy, circular economy work, ESG, or anything adjacent - get in touch if something you're working on might be worth a conversation.
The subsea industry has long treated scrapping as default. Legacy Locker changes that default: refurbishing and reusing critical subsea equipment to eliminate scrap waste and prevent tonnes of virgin manufacturing emissions.
Recognised by the Global Underwater Hub for emerging leadership and meaningful contribution to environmental sustainability and subsea equipment reuse.
Awarded for outstanding contribution to Scotland's decarbonisation agenda, focusing on practical carbon reduction in complex marine operations.
Practical writing on circular loops, Scope 3 decarbonisation, climate risk governance, and closing the gap between strategy and execution.
Why default scrapping in marine engineering is obsolete. Exploring how certified refurbishment cuts up to 80% embodied carbon per unit while satisfying strict offshore safety thresholds.
Spend-based emission factors conceal the operational reality of supply chain footprints. A blueprint for gathering ground-level activity metrics from specialized engineering suppliers.
When glossy TCFD disclosures meet physical operations, operational blind spots emerge quickly. How to bridge the gap between board-level transition plans and day-to-day engineering decisions.
Field notes on why community resource management succeeds or fails, and how early lessons in resource scarcity still define my corporate sustainability philosophy today.
Why operational emissions are only half the picture. Rethinking procurement lifetimes to account for raw material extraction and heavy fabrication footprints.
Industry press features, award announcements, and project milestones across subsea circularity and industrial decarbonisation.
The Global Underwater Hub recognised emerging leaders shaping the future of subsea engineering. Kairvee was honoured for spearheading environmental sustainability and subsea equipment circularity at J+S Subsea.
Recognised for exceptional leadership in Scottish industrial decarbonisation. Commended for translating high-level net zero targets into measurable emissions reductions across complex offshore supply chains.
An in-depth look at Legacy Locker, co-created by Kairvee Tyagi. The initiative redirects operational subsea assets from scrap yards into high-spec refurbishment, eliminating waste and embodied carbon.
Energy Voice spotlights practical environmental leaders driving real-world decarbonisation. Discusses why circularity must be engineered into procurement contracts rather than treated as an afterthought.
