The state gas supply company Uktransgas has failed in two tenders for buying the necessary odorants. As a result, earlier this year local gas suppliers found themselves without the odorant to add to the gas they supply to the Ukrainian houses.
Natural gas has no smell. Odorants are added to the gas to make it possible to notice when there is a leak.
By sabotaging the odorant tenders in order to benefit a related company, Uktransgas has put the lives of millions of Ukrainians at risk.
