Annual greenhouse gas emissions in Liechtenstein fell by 15 percent between 1990 and 2017 – despite the population expanding by around 30 percent over the same period. The greatest fall was recorded in the energy sector. The reasons for this decline in emissions include structural transformation in the economy, more energy-efficient buildings, vehicles and industry, and a fall in fuel sales because fewer people are crossing the border to fill up their cars at lower prices. As a member of the UN Framework Convention on Climate Change, Liechtenstein is obliged to submit an annual report of its greenhouse gas emission levels. INFRAS was commissioned by the Liechtenstein Office of Environment to act as lead author of this report.
