Coronavirus Lockdowns Led to Record 17% Emissions Drop
The researchers found that daily emissions fell by 17 percent during the height of quarantine measures in early April when compared with the same time in 2019, the University of East Anglia (UEA) reported in a press release.
"Globally, we haven't seen a drop this big ever, and at the yearly level, you would have to go back to World War II to see such a big drop in emissions," UEA professor of climate change science and lead author Corinne Le Quéré told NBC News. "But this is not the way to tackle climate change — it's not going to happen by forcing behavior changes on people. We need to tackle it by helping people move to more sustainable ways of living."
🌍 The #COVID19 global #lockdown has had an “extreme” effect on daily carbon emissions, but it is unlikely to last -… https://t.co/HR0vkyM0w0— UEA (@UEA)1589900700.0
The research is the first major study of emissions this year, according to The Guardian, though the International Energy Agency projected a record 8 percent decline in emissions for 2020. Because it is not possible to measure the change in carbon dioxide emission directly, since the gas remains in the atmosphere for such a long time, researchers instead relied on data for on-the-ground indicators like traffic, energy usage, flights and manufacturing, Wired explained.
That data also revealed the major drivers of the emissions decline, the UEA press release explained. The drop in ground transport, such as cars, was responsible for 43 percent of the decline, while declines in industry and power together accounted for another 43 percent. While air travel was majorly impacted by the pandemic, it only accounted for 10 percent of the emissions drop because it is only responsible for three percent of emissions overall.
The data was gathered from 69 countries responsible for 97 percent of greenhouse gas emissions. At the height of the global response, areas responsible for 89 percent of emissions were under some kind of lockdown. On average, countries saw their emissions fall 26 percent. In the U.S. and the UK, emissions fell by a third, Wired reported.
While these numbers are dramatic, they also illustrate the challenges involved in lowering emissions enough to avoid the worst impacts of the climate crisis.
"This is a really big fall, but at the same time, 83% of global emissions are left, which shows how difficult it is to reduce emissions with changes in behaviour," Le Quéré told The Guardian.
She also pointed out to Wired that the 17 percent drop at the height of confinement measures only returned emissions to 2006 levels.
"So this is really showing just how much emissions are increasing through time every year. This incredible drop in emissions only takes us back 14 years," she told Wired.
What happens next will depend on political decisions and how soon lockdown measures are lifted, the press release explained. If they are lifted fully by June, emissions for the year will fall four percent. If some restrictions are in place all year, they will decline by seven percent. That is around the yearly decline needed to meet the Paris agreement climate goals of limiting global warming to "well below" two degrees Celsius above preindustrial levels.
"We would have to have the same speed of reduction that's happening in 2020 every year for the next decade," Zeke Hausfather, a climate scientist at the University of California, Berkeley who was not involved with the study, told NBC News.
The researchers called on governments to craft economic recovery plans that encouraged the systemic changes that will ultimately make sustainable emissions declines possible.
"The extent to which world leaders consider climate change when planning their economic responses post COVID-19 will influence the global CO2 emissions paths for decades to come," Le Quéré said in the press release.
For example, governments could follow the lead of Milan and London in reopening cities in ways that prioritize walking and cycling over driving. Le Quéré suggested to Wired that governments stimulate the economy by directing money towards electric cars.
One positive development is that people around the world now have an illustration of what emissions reductions make possible.
"The most obvious change was the beautiful blue skies we saw from India to Indiana," study coauthor and Stanford University Earth system science professor Rob Jackson told NBC News. "People can relate to that more than abstract discussions about greenhouse gas emissions — you could just see that skies were clear."

Winter is supposed to be the best season for wind power – the winds are stronger, and since air density increases as the temperature drops, more force is pushing on the blades. But winter also comes with a problem: freezing weather.

Ice buildup changes air flow around the turbine blade, which can slow it down. The top photos show ice forming after 10 minutes at different temperatures in the Wind Research Tunnel.

While traditional investment in the ocean technology sector has been tentative, growth in Israeli maritime innovations has been exponential in the last few years, and environmental concern has come to the forefront.
theDOCK aims to innovate the Israeli maritime sector. Pexels<p>The UN hopes that new investments in ocean science and technology will help turn the tide for the oceans. As such, this year kicked off the <a href="https://www.oceandecade.org/" target="_blank" rel="noopener noreferrer">United Nations Decade of Ocean Science for Sustainable Development (2021-2030)</a> to galvanize massive support for the blue economy.</p><p>According to the World Bank, the blue economy is the "sustainable use of ocean resources for economic growth, improved livelihoods, and jobs while preserving the health of ocean ecosystem," <a href="https://www.sciencedirect.com/science/article/pii/S0160412019338255#b0245" target="_blank" rel="noopener noreferrer">Science Direct</a> reported. It represents this new sector for investments and innovations that work in tandem with the oceans rather than in exploitation of them.</p><p>As recently as Aug. 2020, <a href="https://www.reutersevents.com/sustainability/esg-investors-slow-make-waves-25tn-ocean-economy" target="_blank" rel="noopener noreferrer">Reuters</a> noted that ESG Investors, those looking to invest in opportunities that have a positive impact in environmental, social and governance (ESG) issues, have been interested in "blue finance" but slow to invest.</p><p>"It is a hugely under-invested economic opportunity that is crucial to the way we have to address living on one planet," Simon Dent, director of blue investments at Mirova Natural Capital, told Reuters.</p><p>Even with slow investment, the blue economy is still expected to expand at twice the rate of the mainstream economy by 2030, Reuters reported. It already contributes $2.5tn a year in economic output, the report noted.</p><p>Current, upward <a href="https://www.ecowatch.com/-innovation-blue-economy-2646147405.html" target="_self">shifts in blue economy investments are being driven by innovation</a>, a trend the UN hopes will continue globally for the benefit of all oceans and people.</p><p>In Israel, this push has successfully translated into investment in and innovation of global ports, shipping, logistics and offshore sectors. The "Startup Nation," as Israel is often called, has seen its maritime tech ecosystem grow "significantly" in recent years and expects that growth to "accelerate dramatically," <a href="https://itrade.gov.il/belgium-english/how-israel-is-becoming-a-port-of-call-for-maritime-innovation/" target="_blank" rel="noopener noreferrer">iTrade</a> reported.</p><p>Driving this wave of momentum has been rising Israeli venture capital hub <a href="https://www.thedockinnovation.com/" target="_blank" rel="noopener noreferrer">theDOCK</a>. Founded by Israeli Navy veterans in 2017, theDOCK works with early-stage companies in the maritime space to bring their solutions to market. The hub's pioneering efforts ignited Israel's maritime technology sector, and now, with their new fund, theDOCK is motivating these high-tech solutions to also address ESG criteria.</p><p>"While ESG has always been on theDOCK's agenda, this theme has become even more of a priority," Nir Gartzman, theDOCK's managing partner, told EcoWatch. "80 percent of the startups in our portfolio (for theDOCK's Navigator II fund) will have a primary or secondary contribution to environmental, social and governance (ESG) criteria."</p><p>In a company presentation, theDOCK called contribution to the ESG agenda a "hot discussion topic" for traditional players in the space and their boards, many of whom are looking to adopt new technologies with a positive impact on the planet. The focus is on reducing carbon emissions and protecting the environment, the presentation outlines. As such, theDOCK also explicitly screens candidate investments by ESG criteria as well.</p><p>Within the maritime space, environmental innovations could include measures like increased fuel and energy efficiency, better monitoring of potential pollution sources, improved waste and air emissions management and processing of marine debris/trash into reusable materials, theDOCK's presentation noted.</p>
theDOCK team includes (left to right) Michal Hendel-Sufa, Head of Alliances, Noa Schuman, CMO, Nir Gartzman, Co-Founder & Managing Partner, and Hannan Carmeli, Co-Founder & Managing Partner. Dudu Koren<p>theDOCK's own portfolio includes companies like Orca AI, which uses an intelligent collision avoidance system to reduce the probability of oil or fuel spills, AiDock, which eliminates the use of paper by automating the customs clearance process, and DockTech, which uses depth "crowdsourcing" data to map riverbeds in real-time and optimize cargo loading, thereby reducing trips and fuel usage while also avoiding groundings.</p><p>"Oceans are a big opportunity primarily because they are just that – big!" theDOCK's Chief Marketing Officer Noa Schuman summarized. "As such, the magnitude of their criticality to the global ecosystem, the magnitude of pollution risk and the steps needed to overcome those challenges – are all huge."</p><p>There is hope that this wave of interest and investment in environmentally-positive maritime technologies will accelerate the blue economy and ESG investing even further, in Israel and beyond.</p>
