Antibody testing to see if a patient has had coronavirus is becoming more frequent. Many are putting their hopes into using such tests as the basis for immunity ‘passports’ so people can re-emerge back into society without fear of infecting others. Chile and Estonia have begun work on such systems, and we’ll hear from Taavet Hinrikus, the tech entrepreneur who is helping design Estonia’s system. Individual companies are interested in the idea as well, as John Holland-Kaye, the CEO of Heathrow Airport, explains. Meanwhile, companies such as Onfido are racing to design apps to accommodate such a system, while other businesses are wary of whether immunity passports are the right way to get their staff back to work.

Countries around the world are working on ways for people to safely get back to normal, people like Pam in Scotland, who is navigating the world of app dating during coronavirus and wondering when, and if, to meet up. One answer is the idea of an immunity passport or certificate: something that shows you have had coronavirus and are now immune. Franz Walt, chief executive of Swiss firm Quotient, says antibody testing is so accurate it could be the basis for such a system. But Professor Robert West at University College London, says we don’t know enough about the illness to guarantee a passport system would work. And Stanford University historian Kathryn Olivarius explains how a 19th century yellow fever outbreak in New Orleans can help us think about it.

In today’s programme, we’ll be looking at how fake coronavirus cures are marketed and why people are buying them. We’ll also be asking if social media platforms need to do more to stop the flow of disinformation.

Plans for gigantic government investments to decarbonise the world economy are gaining traction, but they may hinge on the US election results in November.

Justin Rowlatt speaks to Spain's deputy prime minister Teresa Ribera about how her government aims to make the country carbon neutral by 2050, as well as a one-trillion-euro EU green recovery plan expected to be unveiled by the European Commission this week.

Meanwhile in the US, the signs are that Democrat Joe Biden will adopt a climate change plan similar in scale to the original 1930s New Deal as the central plank of his election campaign, according to Vox journalist David Roberts.

But what about the world's biggest carbon emitter, China? Justin asks Li Shuo of Greenpeace East Asia whether President Xi will prioritise green investments as part of his country's coronavirus recovery plan, currently being fleshed out at the National People's Congress. And what difference would the US election outcome make to China's willingness to phase out fossil fuels?

How much should employers know about their workers as people head back to the office? Companies have a duty of care to make sure their workers are safe, but how much monitoring is reasonable? Is this the end of privacy at work? Manuela Saragosa hears from Dutch privacy and employment lawyer Philip Nabben, as well as Sam Naficy the CEO of Prodoscore which makes software that monitors employee productivity, and Dr Tomas Chamorro-Premuzic, professor of business psychology at University College London.

Governments are spending billions paying wages to workers who are no longer able to work due to the coronavirus pandemic. How long can we keep this up? Are we storing up problems by offering this type of unprecedented state-sponsored handout long-term?

We hear from an employee in the tourism industry who has been furloughed, a hotel owner in the North of England who has had to furlough most of his staff, as well as Torsten Bell from the Resolution Foundation think tank who originally proposed the scheme in the UK before it was adopted, and Eamonn Butler from the free-market think tank the Adam Smith Institute who argues that the system is open to abuse.

A third of Venezuela's population is at risk of malnutrition, according to the UN and the latest gasoline crisis could weaken the country's economy further. Entire villages are said to have been cut off from food supplies because trucks can't get fuel to deliver to them. That’s the context a crisis which has made Venezuela the world’s weakest emerging economy, according to a recent review by the Economist magazine. Earlier this month the situation became even more volatile when two Americans were caught apparently trying to launch a coup attempt against the government. We hear from Adam Tooze, a professor of history at Columbia University and we get the views of Venezuelan opposition politician Manuela Bolivar.

How do you feed a world in lockdown? We’ll be looking at the pressures on the global food supply chain in this episode of Business Weekly. As many choose to buy more locally produced food we’ll ask whether new habits will stick. Two renowned economists tell us that any governments handing out Coronavirus bailouts must learn the lessons from the financial crisis of 2008 and impose tighter conditions. ABBA’s Bjorn Ulvaeus speaks to us about life in Sweden during the pandemic and gives us his thoughts on fellow countrywoman Greta Thunberg. Plus - has the coronavirus forever changed the workplace as we know it? Lucy Burton presents.

Coal has suffered the brunt of the huge slump in electricity demand as the world has gone into lockdown. It has highlighted the fossil fuel's Achilles Heel: When there is too much supply on the grid, it's coal-fired power stations that get switched off, not solar or wind.

Justin Rowlatt speaks to the head of the International Energy Agency Fatih Birol, as well as analysts covering the two countries most central to coal's future. Delhi-based Sunil Dahiya says that India is already reckoning with renewable energy that is cheaper 24/7 than the cost of operating its existing coal fleet. Meanwhile Shirley Zhang of energy analysts Wood Mackenzie says that China's plans to build new coal-fired power stations is already baked in.

Plus, Business Daily's favourite chemistry professor, Andrea Sella of University College London, explains why coal played such a central role in getting the Industrial Revolution started, with the help of an uncooperative steam engine.
