İpek Göktaş Kalkan

I'm İpek Göktaş Kalkan. I have been working in EPD, LCA and sustainable building products for over 15 years.

Throughout my career I have worked on both sides of the EPD process — as an LCA practitioner preparing EPDs and as an independent third-party verifier. This dual perspective means I approach every project not only from a modelling and reporting standpoint, but also from the angle of what will actually be scrutinised during verification.

My background in green building also shapes how I see EPDs. I don't treat them purely as technical documents. I understand how they are positioned in the building products market, how they are used in green building projects, and what value they can genuinely create for manufacturers.

I work as an approved independent EPD verifier on four international EPD programmes, including The International EPD® System.

EPDlogy was founded by me in Helsinki in 2026. My aim is to help manufacturers navigate EPD and LCA processes in a way that is clearer, more controlled and ready for verification.

For me, an EPD project is not just about running calculations or producing a results table. From the very start, it requires the right PCR framework, clearly justified assumptions, controlled data quality and early identification of potential verification risks.
