Only weeks before world leaders gather in Glasgow to hammer out plans to slow climate change, the United Nations Economic Commission for Europe (UNECE) has released a document arguing that nuclear power can help deliver on the Paris Agreement and the 2030 Agenda for Sustainable Development.
“Nuclear power is an important source of low-carbon electricity and heat that can
contribute to attaining carbon neutrality and hence help to mitigate climate change,” UNECE Executive Secretary Olga Algayerova said.
In the new technology brief published on Wednesday, the agency warned that “time is running out to rapidly transform the global energy system,” as fossil fuels still account for over half of electricity generation in the UNECE region, which include the countries of Europe, but also countries in North America, Central Asia and Western Asia.
The report highlights how only hydropower has played a greater role in avoiding carbon emissions over the past 50 years.
Nuclear power is a low-carbon energy source that has avoided about 74Gt of CO2 emissions over this period, nearly two years’ worth of total global energy-related emissions, it noted.
Yet nuclear power currently provides 20 per cent of electricity generated in the UNECE region and 43 per cent of low-carbon generation.
Still time to limit climate change
The publication comes as the Intergovernmental Panel on Climate Change (IPCC) released its landmark report on Monday, warning that some climate change trends are currently now irreversible, but there is still time to limit it with strong and sustained reductions in emissions of carbon dioxide (CO2) and other greenhouse gases.
The UNECE document also highlighted a 2018 report by the IPCC which sees demand for nuclear generation increase six times by 2050 with the technology providing 25% of global electricity. Nuclear power, it stated, has the potential to increase its integration with other low-carbon energy sources in a future decarbonised energy mix.
Powering the region
According to the document, in the UNECE region, nuclear power is providing over 30% of electric generation in eleven countries (Belgium, Bulgaria, Czech Republic, Finland, France, Hungary, Slovakia, Slovenia, Sweden, Switzerland, Ukraine).
Twenty countries currently operate nuclear power plants, and fifteen countries have new reactors under construction or under development. Seven UNECE member States are in the process of developing nuclear power programmes for the first time.
A number of countries – such as Canada, Czech Republic, Finland, France, Hungary, Poland, Romania, Slovakia, Slovenia, Russia, Ukraine, the United Kingdom and the United States – have explicitly stated that nuclear power will play an important role in reducing their national emissions in the future.
