Australia’s greenhouse gas emissions fell 5.3 per cent in the year to March 2021 as coronavirus lockdowns reduced transportation exhaust and increases in solar and wind power cut emissions from electricity generation, according to data released yesterday.
Reuters said emissions fell to 494.2 million tonnes of carbon dioxide equivalent (CO2-e) as of March 2021 from 521.9 million tonnes CO2-e a year earlier, the Department of Industry said in a quarterly report.
“While there is still work to be done, this data shows the government’s comprehensive suite of policies to meet its emissions reduction commitments, encourage innovation and back new and emerging low emissions technologies are working,” Energy Minister Angus Taylor said in a statement.

Australia remains one of the world’s worst greenhouse gas emitters per capita. Its conservative government faces international pressure to step up its commitment to cut emissions by 2030 ahead of United Nations climate talks in Glasgow in November.
Under the Paris Climate Agreement, Australia has committed to cut emissions by between 26 per cent and 28 per cent by 2030, while other nations, including the United States, Britain and Canada, have ramped up targets, committing to reduce greenhouse gases by 40 per cent or more by 2030.
As of March 2021 Australia’s emissions were down nearly 21 per cent from 2005.
Emissions from the transport sector dropped 13 per cent in the year to March 2021 because of COVID-19 restrictions, the Department of Industry report said.
Emissions from the power sector fell 5.6 per cent as wind and solar power output jumped, displacing some coal- and gas-fired generation.

The latest figures came at the same time that the Australian Energy Market Operator (AEMO) said at current rates of wind and solar farm development the national electricity market could have enough renewable power available in 2025 to meet 100 per cent of consumer demand at certain periods.
That compares with recent records when renewable power met 57 per cent of demand on two occasions this year.
AEMO forecasts Australia’s uptake of rooftop solar, already the highest in the world with one in four homes having solar panels, is expected to jump 64 per cent to 22.9GW by 2025 from current levels.
