The EU saw an increase of 1.8% in carbon emissions last year compared to 2016.
According to latest statistics from Eurostat, emissions rose in a majority of member states, with the highest increase recorded Malta, followed by Estonia, Bulgaria, Spain and Portugal.
However, seven member states saw a fall – Finland, Denmark, the UK, Ireland, Belgium, Latvia and Germany.
CO2 emissions are a major contributor to global warming and account for around 80% of all EU greenhouse gas emissions.
They are influenced by factors such as climate conditions, economic growth, size of the population, transport and industrial activities.
