🇲🇹 Malta's Sources of CO₂ Emissions

Malta's Sources of CO2 Emissions

✨ Key Insights

Coal's Decline and Oil's Rise

In the mid-20th century, Malta's CO2 emissions were primarily driven by coal, reflecting the global reliance on this fossil fuel. However, by the 1980s, coal's contribution to emissions had significantly diminished, with oil taking the lead. This shift coincided with Malta's post-independence industrialization, which saw increased infrastructure development and energy consumption. The closure of British military bases in 1979 also marked a turning point, as the repurposing of these areas likely contributed to the rise in oil-based emissions.

Natural Gas and EU Influence

The introduction of natural gas in 1987 marked a pivotal moment in Malta's energy landscape. This cleaner-burning fuel began to replace oil, contributing to a gradual reduction in CO2 emissions. Malta's accession to the European Union in 2004 further influenced emissions trends, as EU membership brought regulatory changes and funding for development projects. While these developments initially increased energy consumption, they also introduced stricter environmental regulations, helping to mitigate emissions.

Recent Shifts and Future Outlook

The conversion of the Delimara Power Station to natural gas in 2013 and the completion of the electricity interconnector with Sicily in 2017 were significant steps towards reducing Malta's carbon footprint. These initiatives decreased reliance on local fossil fuel-based power generation, leading to a notable decline in CO2 emissions. As Malta continues to embrace cleaner energy sources, its emissions profile is likely to improve, aligning with global efforts to combat climate change.

Background

The chart shows a national breakdown by source of the yearly CO2 emissions from human activities and processes expressed in megatonnes. It is critical to know and track the sources of national CO2 emissions in order to understand their individual impacts on climate change.

The sources of human CO2 emissions are

  • CO2 From Fossil Fuels and Industry: coal, oil, gas combustion, other fossil processes
  • CO2 From Land-Use, Land-Use Change, and Forestry

Coal, oil and gas combustion

Fossil fuel CO2 emissions from the combustion of coal, oil and gas are emitted by processes in electricity generation, transport, industry, and the building sector. All processes can be linked to human activities. Examples include driving cars with combustion engines burning diesel or gas, or electric cars charged by electricity from a power plant that burns coal.

Other fossil processes

Fossil CO2 emissions from other processes include sources like cement manufacturing and production of chemicals and fertilizers. Cement also has an absorption factor highlighted in the absorption breakdown chart.

Land-use change

Human civilization emits CO2 by changing and managing its land. Those emissions come, for example, from deforestation, logging, forest degradation, harvest activities and shifting agriculture cultivation. Land-use change also absorbs considerable amounts of CO2, which is shown in the absorption breakdown chart. Land-use change emits more than it absorbs, so the net effect is still emissions, but less than for coal, oil and gas.

Units and Measures

CO2 emissions are expressed in the total weight in megatonnes per year. 1 Megatonne is equal to 1 million tonnes.

About the Data

The last available year is 2023. CO2 emissions data is from the Global Carbon Project. It contains national CO2 emissions from fossil sources and land-use change.

The Key Insights paragraph was generated using a large language model (LLM) using a structured approach to improve the accuracy. This included separating the context generation from the interpretation and narrative.
