Picture this: the bustling streets of Valletta, the capital city’s iconic yellow buses purring along Republic Street, yet their exhaust fumes seem less prevalent. You’re not imagining things. According to the latest report from the Central Bank of Malta, greenhouse gas emissions on our tiny island nation have been quietly falling, not rising as many had feared.

A Tale of Two Trends

Contrary to the global trend of escalating emissions, Malta’s greenhouse gas emissions have decreased by 12.5% between 2015 and 2019. This revelation, tucked away in the Central Bank’s annual report, is a nugget of good news that deserves a closer look. While the global average emissions per capita stand at around 6.5 tonnes, Malta’s has dropped to 5.7 tonnes, a significant dip from the 6.5 tonnes recorded in 2015.

But let’s not get carried away with the celebrations just yet. This decline is not uniform across all sectors. The report highlights that while emissions from the residential sector have decreased by 20%, those from the transport sector have increased by 18%. This suggests that while we’re making strides in energy efficiency at home, our reliance on fossil fuels for transportation remains a significant challenge.

The Power of Renewables

So, what’s driving this decrease in emissions? The answer lies in our increasing reliance on renewable energy sources. Malta’s solar power capacity has more than doubled since 2015, with solar photovoltaic (PV) installations now found on rooftops across the island, from the historic streets of Mdina to the modern skylines of Birkirkara. Wind power has also seen a significant boost, with the Delimara 3 power station now capable of generating 20MW of electricity from wind alone.

the closure of the Delimara power station’s oldest units and the introduction of more efficient combined cycle gas turbine (CCGT) units have also contributed to the reduction in emissions. The new CCGT units, which began operation in 2018, are not only more efficient but also emit less carbon dioxide per unit of electricity generated.

The Road Ahead: A Balancing Act

While these figures paint a promising picture, they also underscore the challenges that lie ahead. Malta’s commitment to reduce its greenhouse gas emissions by 40% by 2030, as part of the EU’s climate and energy framework, will require sustained effort and investment in renewable energy sources. This includes not just solar and wind power, but also exploring innovative solutions like wave and tidal energy.

At the same time, we must address the elephant in the room: our transport sector’s reliance on fossil fuels. This could involve incentivizing the adoption of electric vehicles, improving public transport, and promoting cycling and walking. After all, Valletta’s streets are not just for buses; they’re also for people.

As Malta continues to navigate its path towards a low-carbon future, let’s not forget that every tonne of emissions avoided is a step in the right direction. And who knows, maybe one day soon, Valletta’s streets will be not just bustling, but also cleaner and greener.
