In 1991 Sweden introduced a substantial CO2 tax. Though it had many exemptions and was subject to many changes over the years, it did cut emissions. During that time, Sweden also phased out two nuclear reactors.
The EU burden sharing agreement in 1997–98 allowed Sweden a plus four per cent GHG target for 1990–2010. This was motivated by Sweden’s supposed plans to phase out nuclear power by 2010, plans that were already abandoned.
