The chemical company said on Monday that it had observed these emissions during an inspection in 2018 in Visp (VS). They were reported to the Federal Office for the Environment (FOEN). Lonza has committed to installing a catalyst for an amount of 12 million francs, in order to reduce its emissions by at least 98% by the end of 2021. It has already taken the first steps, confirmed the FOEN.
This climate-damaging gas is emitted during the production of vitamin niacin. Lonza has operated a facility for this purpose since 1971. These emissions are not regulated by the Air Protection Ordinance and the company has therefore never analyzed them.
Since the beginning of the year, nitrous oxide emissions have been listed in the Swiss emission allowance trading register. As Lonza is registered in this register, it must remit to the Confederation emission rights or foreign certificates also for this gas.
Switzerland is committed to reducing its emissions by 15.8% on average compared to 1990 for the years 2013 to 2020. The 600,000 tonnes of CO2 equivalents emitted by Lonza undermine this objective. In order to reach the target of the Kyoto Protocol, the Climate Centime foundation will acquire foreign certificates up to 5 million tonnes of CO2 and transfer them to the Confederation.
