Global energy-related emissions flatlined in 2019, new data released by the International Energy Agency (IEA) indicates.
The Agency found that power sector emissions have declined to levels last
seen in the 1980s, although 33 gigatonnes of emission were sent into the
atmosphere over the course of last year.
The IEA study cites
the reduced use of coal as one of the main drivers of the flatline, with fossil
fuel use in general down nearly 15 per
cent as countries switch to renewables, as well as nuclear power.
The trend is also due
in part to milder weather in several countries last year in tandem with slower
than expected economic growth in some emerging markets.
The United States saw
the largest emissions decline in the study of almost one gigatonne, while the EU
saw a five per cent emissions reduction of almost 160 million tonnes.
Natural gas exceeded
coal in electricity production for the first time in 2019, and wind-powered
electricity has now almost caught up with coal-fired electricity.
emissions in other parts of the world grew by close to 400 million tonnes in
the same time period, with almost 80 per cent of the increase coming from Asia where
coal-fired power generation continues to expand.
IEA Executive Director
Dr Fatih Birol said the findings are “grounds for optimism” but that countries
will need to work hard to make sure that 2019 marks a “definitive peak in
global emissions, not just another pause in growth”.
While the report
focused on the power sector and presented a potentially optimistic case for the
industry going forward, power generation is only one piece of the puzzle in
emission reductions for governments.
transport for the most part continue to maintain their high-emitting status and
climate feedback loops also allow for additional emissions.
Wildfires, such as the
ones that swept California and Australia, also emit their own carbon dioxide
through deforestation and particulate matter pollution.
Higher temperatures stretch out fire seasons in dry parts of the world, which can lead to more severe and longer wildfires that can themselves lead to higher temperatures in the future.
