Greenhouse Gas Emissions Set for Record Decline
Due to Coronavirus Lockdowns

The decline
in energy demand driven by coronavirus lockdowns will trigger a record fall in
greenhouse gas emissions, the International Energy Agency (IEA) said Thursday.
The
Paris-based agency predicted a drop of eight percent, almost six times the last
record, set in 2009 and triggered by the global financial crisis. It is also
twice as steep as all emissions declines since World War II combined. However,
the agency cautioned that this decline on its own is not a solution to the
climate crisis.
"Resulting
from premature deaths and economic trauma around the world, the historic
decline in global emissions is absolutely nothing to cheer," IEA Executive
Director Dr Fatih Birol said in a press release. "And if the aftermath of
the 2008 financial crisis is anything to go by, we are likely to soon see a
sharp rebound in emissions as economic conditions improve."
Birol did
note, however, that a rebound in emissions is not inevitable, as he added his
voice to the growing global call for a green recovery process.
"[G]overnments
can learn from [the post-2008] experience by putting clean energy technologies
– renewables, efficiency, batteries, hydrogen and carbon capture – at the heart
of their plans for economic recovery," he said. "Investing in those
areas can create jobs, make economies more competitive and steer the world
towards a more resilient and cleaner energy future."
The IEA's
Global Energy Review is based on more than 100 days of data so far this year.
It predicts that global energy demand will fall by six percent in 2020, the
equivalent of losing the entire energy demand of India and seven times the 2008
decline.
All major
fossil fuels have taken a beating so far and are expected to decline further.
Coal demand
fell by almost eight percent in the first quarter of 2020 and could fall eight
percent for the whole year.
Oil
declined by almost five percent in the first quarter and could fall by nine
percent for the year.
Natural gas
declined by two percent so far and is expected to fall by five percent for the
year, The Guardian reported. While gas has been less impacted than oil and
coal, that would still be its steepest decline since it became a widely-used
energy source in the mid-20th century.
Only
renewable energy sources saw growth, and are expected to continue to grow
throughout the year. This is because wind turbines and solar panels cost little
to operate, so when electricity demand declines, they get priority on the grid,
The New York Times explained.
This means
low carbon energy sources are expected to continue moving in the direction that
began in 2019, when they overtook coal as the world's leading source of
electricity for the first time in 50 years. By the end of 2020, they should
account for 40 percent of the world's electricity.
"This
is a historic shock to the entire energy world. Amid today's unparalleled
health and economic crises, the plunge in demand for nearly all major fuels is
staggering, especially for coal, oil and gas. Only renewables are holding up
during the previously unheard-of slump in electricity use," Birol said.
"It is still too early to determine the longer-term impacts, but the
energy industry that emerges from this crisis will be significantly different
from the one that came before."
The IEA
estimates are based on certain assumptions, namely that lockdown measures are
loosened in the coming months and the economy begins to recover.
"Some
countries may delay the lifting of the lockdown, or a second wave of
coronavirus could render our current expectations on the optimistic side,"
Birol told Reuters.
The
question for climate advocates is whether the decline in emissions can be
sustained. This is a tall order. The United Nations has estimated that
emissions need to decline by around eight percent per year through 2030 in
order to keep temperatures "well below" two degrees Celsius above pre
industrial levels, The New York Times reported.
However,
the declines in air pollution that have accompanied the lockdowns may provide
an effective argument for cleaner energy.
"I
hope the striking improvements in air quality we've seen remind us what things
could be like if we shifted to green power and electric vehicles,"
Stanford University earth scientist Rob Jackson told The New York Times.
