Since 1990, the Czech Republic has reduced its greenhouse gas emissions by over 30%, far exceeding the Kyoto Protocol target of 8%, according to a recent country report by the OECD. But its emission intensity, (the level of emissions per unit of economic output) is one of the highest among the mostly rich-country group of the OECD. The country’s primary energy supply is coal, which helps explain its high carbon emissions. But unlike any of the other carbon-intense countries the Czech Republic also uses nuclear power. This explains why it has been able to do so well against Kyoto targets, despite also having coal-fired plants with an average age of 50 in 2009.
