Global carbon emissions fell 17% during coronavirus blockages
May 22 2020
China, the world's biggest emitter of heat-trapping gases, sliced its carbon pollution by almost a quarter, that is by 23.9%, in February.
The Technology Investment Roadmap Discussion Paper that has recently been released will accelerate emissions reduction in Australia through a sensible and systematic approach based on current and future low emissions technologies which offer the best prospects for Australia.

Global stay-at-home orders have caused a dramatic plunge in carbon emissions.
A TSA agent speaks to travelers passing through an empty security queue at Love Field airport in Dallas, Thursday, March 12, 2020, amid concerns of the coronavirus pandemic. "To put that figure in context, daily emissions declined on average between January to April by 8.6 percent again compared to the same period past year".
The team analyzed government policies on confinement for 69 major carbon-emitting countries.
In the U.S., California and the state of Washington saw the biggest decline in emissions, produced from burning oil, gas and coal.
The findings show the world has experienced the sharpest drop in carbon output since records began, with large sections of the global economy brought to a near standstill. Countries have needed less power, so that sector makes up 19 percent of the global emissions change; industry covers one-quarter, and aviation (which has been significantly hit) makes up 10 percent of the emissions difference.
"The change for the rest of the year will depend on the duration and extent of the confinement, the time it will take to resume normal activities, and the degree to which life will resume its preconfiment course", the researchers wrote.
In early April, the researchers found, the regions responsible for 89% of global emissions were under some type of lockdown.
They studied energy data and weather data sourced from different sources in more than 400 cities and 130 countries to produce daily estimates of carbon emissions for 2019 and 2020. That, if we are to compare it to the daily emissions from 2019.
But the researchers warned that such cuts would be needed for years to come to limit climate change to an increase of 1.5C from pre-industrial levels. The National Covid-19 Coordination Commission is heavily backing gas to drive the economic recovery.
Will they step up and use the stimulus spending to achieve the goals of the UN's Paris Climate Agreement to keep temperatures to well below 2 deg C and net-zero Carbon dioxide emissions by 2050?
"As various nations and segments recoup, it is muddled if action levels will come back to typical levels or on the off chance that we may see changeless moves in conduct", he included. "We need systemic change through green energy and electric cars, not temporary reductions from enforced behavior".
