Three reasons why this was a good day for the planet 

This bad day for the oil and gas corporations gives hope for a better future.

May 27




Let me start with a high school memory of the early 1980s, where we had to grow fruit flies in a bottle. Each time we had biology class, I watched the population increase. They seemed to have had a pretty good life; enjoying their food and reproduction were their main activities. They were the masters of their little universe, without predators or other threats. Until their last round of multiplying their numbers was a bridge too far. Not one survived the destruction of their little glass-bottled paradise after a final day of fierce competition for the last resources.

Each of those fruit flies was worried about the future of life in their bottle, and they likely all agreed that another fruit fly should start to change its lifestyle. A bottle has no judge nor any form of responsible leadership.

 

Shell

Today, at about a 15-minute drive from that high school, a Dutch court ordered Royal Dutch Shell to cut its carbon emissions by a net 45% by 2030 compared to 2019 levels. The judge ruled that the current reduction plans of the Anglo-Dutch energy multinational were not enough and that Shell has a duty of care to reduce emissions. The corporation should bring its emission reductions, suppliers, and buyers into line with the Paris climate agreement.

The judge said Shell must "at once" reduce its CO2 output and that the ruling would have "far-reaching consequences" for the company and may "curb the potential growth of the Shell group." She added that "The interest served with the reduction obligation outweighs the Shell group's commercial interests."

Today was a good day for the planet. Climate activism won, and this decision will likely set a precedent for similar cases against other fossil fuel companies. Today's decision brings back memories of two years ago when the Dutch Supreme Court upheld a 2015 decision that required the government to cut back greenhouse gas emissions by at least 25 percent by the end of 2020 from 1990 levels. It was a source of inspiration for activists that started similar cases in other countries. But these cases were against governments, while this is the first case won against a multinational. 

 

ExxonMobil

There was more good news for the planet today. Shell competitor ExxonMobil had other worries on its mind. Dissident hedge fund activists successfully staged a coup against its board. They replaced two Exxon board members with their candidates to push towards a greener strategy for the oil and gas multinational.

Chevron

And the good news for the planet continued. At about the same time, a majority of 61 percent of Chevron shareholders voted in favor of a proposal from the campaign group Follow This. It forces the multinational energy corporation to cut its carbon emissions, including those caused by its customers burning its products. The Dutch seem to be everywhere in these developments; Follow This is also a Dutch campaign, led by its founder Mark van Baal.

Was this just a lucky day for the planet? No, what we see are the first signs of a structural change. Increasingly, shareholders are frustrated by the lack of innovative action and demand leadership committed and capable of delivering a much faster track towards a green energy transformation. Some of them support the activists that can campaign and mobilize but can't create change by their numbers. Engine No.1, which initiated the campaign at ExxonMobil, owns just 0.02 percent of the shares but received the support of BlackRock, the world's biggest asset manager, which holds a 6.7% stake in Exxon.

There is more good news in 2021

There are more signs that this is a year of change. I could write pages full of bad news, like the profoundly worrying predicted steep increase in greenhouse gas emissions. Still, there are signs that climate action finally becomes much more mainstream and that fundamental transformation occurs. That is, for my taste, still too late and not fast enough, but I realize that we will never get this problem solved if we don't start with good initiatives, and today's developments fit in a bigger picture of hope.

The U.S., the second-largest emitter of greenhouse gasses worldwide (and historically and per capita the biggest), has radically changed its course from climate denier to an active player towards more climate action.

This year in November, the all-important COP26 in Glasgow should increase ambitions worldwide towards reducing emissions and other forms of climate action.

Last week, the International Energy Agency declared that we should end investments in new coal mines, oil and gas wells to meet the 2050 climate goals. This message comes doesn't come from some friendly tree-huggers but the IEA. That is the most authoritative energy body in the world and for many years an organization with a reputation of being close to the fossil fuel industry.

A recent article in Bloomberg Green showed that green bonds and loans from the global banking sector exceed the value of fossil financing so far this year. That is an unprecedented reversal since the Paris Agreement of 2015. Add to this the IEA analysis stating that 90 percent of the newly built power capacity worldwide comes from renewable energy.

Victoria’s seven day lockdown, which begins tonight, is an attempt to stop transmission of the quick-spreading COVID-19 B.1.617.1 variant.

Victoria’s chief health officer Brett Sutton said the reproduction number of the strain was yet to be determined, but could be five or more, meaning one person would infect five others.

B.1.617.1 is one of three so-called “Indian” SARS-CoV-2 variant sub-types. Little is known about it but it’s likely to have similar characteristics to the sub-type dominating in India and emerging in the United Kingdom at the moment, B.1.617.2.

Remind me, what’s a variant of concern?

To be classified as a variant of concern, it must pose a risk to public health over and above the original Wuhan virus. This could be due to changes in transmissibility (how easily it spreads), disease severity, its ability to evade detection by viral diagnostic tests, reduced effectiveness of treatments, or an ability to evade natural or vaccine-induced immunity.

The World Health Organization is tracking four variants of concern, which are often referred to by the country in which they emerged:

The B.1.617 variant, which was classified as a variant of concern on May 6 2021, has three subtypes – B.1.617.1, B.1.617.2 and B.1.617.3 – each with small differences in their genetic make-up.

What do we know about the ‘Indian’ variants?

Information about B.1.617 is emerging, but early reports indicate it spreads more easily than the original strain. Although there is limited data specifically on B.1.617.1, it is likely to behave similarly to B.1.617.2 as it is genetically similar.

Early data from the UK’s NHS Test and Trace records showed B.1.617 spreads at least as easily as the UK strain (B.1.1.7). In fact, B.1.617.2 may be twice as likely to infect another person than the UK strain, which was already more infectious than the original Wuhan virus.

The relative disease severity of B.1.617 is still under investigation, however even if it is no more severe than the original virus, increased transmission leads to more cases, more hospital admissions and more deaths.

Laboratory tests also raise the possibility that reinfection might be more common with the B.1.617 variant, but this is yet to be confirmed by real-world data and for all sub-types.

How effective are vaccines and how long do they take to kick in?

For most variants of concern, vaccines are still effective, but are often less effective than they were against the original Wuhan virus.

So far, there are no data on how effective any of the COVID-19 vaccines are against B.1.617.1.

B.1.617.2 has one more mutation than B.1.617.1, so they are genetically similar. Therefore the vaccine effectiveness against B.1.617.1 and B.1.617.2 is likely be similar, but this is not known yet.


Made with Flourish


Data from the UK (non-peer reviewed) on vaccine effectiveness against the B.1.617.2 variant has recently been released. It found:

  • both Pfizer and AstraZeneca are 33% effective against symptomatic disease (COVID-19 symptoms such as fever, dry cough and tiredness) three weeks after the first dose
  • Pfizer vaccine is 88% effective against symptomatic disease two weeks after the second dose
  • AstraZeneca vaccine is 60% effective against symptomatic disease two weeks after the second dose.

The difference in effectiveness between the vaccines after two doses may be due to AstraZeneca taking longer to reach peak protection as this occurs after two weeks following the second dose.

Both vaccines are expected to provide even greater protection against COVID-19 hospitalisation and death than they do for symptomatic disease. As yet there are too few cases to do this analysis but this will take place over the coming weeks.

Lower vaccine effectiveness means even if you are vaccinated, you could still get infected. However, if an infection does occur, symptoms would be milder.

It’s also possible vaccination may not protect you for as long against this sub-type compared to other variants. But this is not known yet for B.1.617.1.

Time between doses

From December 2020, the UK had been delivering the AstraZeneca and Pfizer vaccines with a 12-week interval between doses to provide some protection to as many people as possible.

A recent study supported this decision, finding that extending the vaccine interval from three to 12 weeks for the second dose boosted the immune response in people over 80 by 3.5 times.

However, due to the spread of the B.1.617.2 variant in the UK, the strategy was changed in mid-May to an eight-week gap in order to provide greater protection from this highly transmissible virus at an earlier opportunity.

Australia delivers the AstraZeneca vaccine with a 12-week interval, while opting for three weeks for Pfizer.

Decisions on the timing between doses must balance providing greater protection earlier, against providing some protection to the maximum number of people. It’s too early to make those changes right now for Victoria but this option should be considered if the outbreak worsens.

Should people get vaccinated?

Even though we don’t know how effective vaccines are against the B.1.617.1 sub-type, don’t delay getting vaccinated. This time our outbreak is due to B.1.617.1, but next time it could be another variant.

COVID-19 vaccines are equally effective against the original strain and B.1.1.7, and are also effective against the B.1.617.2 variant (albeit a bit lower).

During an outbreak, policymakers should also consider opportunistically increasing vaccine uptake, especially in the outbreak areas. Victoria has made progress in this area and from tomorrow all 40- to 49-year-old Victorians will be offered Pfizer.

But those responsible for the most COVID-19 transmission are aged 20 to 49 years. So vaccinating even younger Victorians – 20 to 39 year olds – would also prevent spread of the outbreak. Even if the vaccine was only 20% effective against transmission this may be a very important additional measure.

Even though there are many unknowns, it is still important to get vaccinated with the vaccine that is offered right now.
