Dr. Bjorn Lomborg researches the smartest ways to do good. With his think tank, the Copenhagen Consensus, he has worked with hundreds of the world’s top economists and seven Nobel Laureates to find and promote the most effective solutions to the world’s greatest challenges, from disease and hunger to climate and education.

Best Things First – The top 12 solutions for the world

The Sustainable Development Goals are supposed to be delivered by 2030. World leaders have promised everything, like eradicating poverty, hunger and disease; stopping war and climate change, ending corruption, fixing education along with countless other things. But they are failing to deliver on their 169 promises at halftime.If we can’t do everything, let’s do the best things first — this is the message of Bjorn Lomborg’s brand new book.* Together with more than a hundred of the world’s top economists, he has worked for years to identify the best solutions to make the world a better place.

The book details how the 12 most cost-effective policies for the world can save 4.2 million lives and generate $1.1 trillion additional income for the world’s poorer half. Each dollar spent delivers an astounding 52 times the benefits.

It is strongly endorsed (”remarkable,” ”insightful,” ”incredible,” ”amazing,” ”spectacular,”  “thought-provoking,’ “Best Things First is the book to read”) by eminent voices in the global development conversation including Larry Summers, Bill Gates, the Chief Economist of the World Bank, a Nobel laureate and the Indian Prime Minister’s Chief Economic Advisor.

In a glowing review of the research project the book is based on, Canadian newspaper Financial Post writes:

Priorities, priorities, priorities. Results, results, results. Bjorn Lomborg (…) certainly understands the economic approach to problems. Choose. Don’t attempt everything. Put your resources where they will do the most good. (…) If calling his approach “economic” sours you on it, how about “evidence- not aspiration-based”?

Proven methods that will radically improve learning

One thing that taxpayers and politicians agree on practically everywhere is that more money should be spent on children’s education. But we need to be careful. Many popular educational investments deliver little or no learning, while we rarely hear about the most effective investments.

New research for Copenhagen Consensus highlights two cheap and efficient ways to increase learning. Tablets with educational software used just one hour a day over a year cost only $20 per student and result in learning that normally would take three years. Semi-structured teaching plans can make teachers teach more efficiently, doubling learning outcomes each year for just $10 per student.

We could dramatically improve education for almost half a billion primary school students in the world’s poorer half for less than $10 billion annually. This investment would generate long-term productivity increases worth $65 for each dollar spent.

Each week, Bjorn Lomborg is writing about the 12 most phenomenal solutions for global development in 35+ newspapers worldwide. You can read his article on education in publications including National Post(Canada), The Australian, The Nation (Kenya), Business Day (South Africa), Daily Graphic (Ghana), Addis Fortune(Ethiopia), New Times (Rwanda), Daily Mail (Zambia, print only), The Nation (Malawi, print only), Philippine Daily Inquirer, Dhaka Tribune (Bangladesh), Bangkok Post (Thailand), DC Journal (USA), Tempi (Italy), Portfolio (Hungary), Finmag (Czech Republic), Milenio(Mexico), La Prensa (Nicaragua), El Universal(Venezuela), Jordan Times, Al-Ahram (Egypt) and An-Nahar (Lebanon, in Arabic).

Skilled migration can address inequality

Smart migration policies can reduce inequality. Enabling more skilled migration to countries that need more skilled labor could achieve both higher productivity and less inequality.

Surprisingly, our new studyfinds that even the countries where migrants originate will see more benefits than costs.

Each dollar spent on increasing skilled migration by 10% will deliver a substantial $18 of social benefits globally.

How India can use its G20 leadership to prioritize the best solutions for the world

Bjorn Lomborg recently traveled to New Delhi to speak at India’s biggest news event, the Republic Summit, sharing the stage with many of the federal ministers and Prime Minister Narendra Modi.

Discussing both climate policy and global development, he pointed out that India has made the fastest progress on the Sustainable Development Goals of any G20 nation, and argued that India should use its G20 leadership to prioritize the best solutions for the world.

As a voice for the Global South, India should insist on most efficient solutions for health, education, nutrition and other areas in which smart investments can create a huge impact to improve people’s lives.

While in New Delhi, Lomborg also appeared on one of the largest political talk shows of the country, Nation Wants To Know, to discuss smart solutions to climate change and how to turn the SDGs into a success story.

Bednets can save more than a million lives

We think of malaria as a problem faced only by humid, hot countries. But just over a century ago, the disease thrived as far north as Siberia and the Arctic Circle, and was endemic in 36 states of the U.S. Today, much of the malaria problem has stubbornly remained in Africa, where it kills more than half a million people every year.

Our new research proposes a 10 percent point scale-up and use of bednets in the 29 highest-burden countries in Africa alongside insecticide resistance management strategies, between now and the end of the UN’s 2030 promises. This investment will save 30,000 lives even in 2023. By the end of the decade, the number of malaria deaths will be halved, saving some 1.3 million lives in total. Every dollar spent on this campaign would yield societal benefits worth $48—a phenomenal return on investment.

Bjorn Lomborg writes about this study in his column for newspapers around the world, including The Nation(Kenya), Business Day (South Africa), Daily Graphic(Ghana), Addis Fortune (Ethiopia), Daily Mail (Zambia, print only), The Nation (Malawi, print only), National Post (Canada), Navbharat Times (India, in Hindi), Dhaka Tribune (Bangladesh), Jakarta Post (Indonesia), Philippine Daily Inquirer, DC Journal (USA), Tempi(Italy), Portfolio (Hungary), Standard (Slovakia), Finmag(Czech Republic), Morgunbladid (Iceland), El Periodico(Guatemala), La Prensa (Nicaragua), El Universal(Venezuela), An-Nahar (Lebanon), Al-Ahram (Egypt) and Jordan Times.

Net zero’s cost-benefit ratio is crazy high

Published on

From the Fraser Institute

By Bjørn Lomborg

The best academic estimates show that over the century, policies to achieve net zero would cost every person on Earth the equivalent of more than CAD $4,000 every year. Of course, most people in poor countries cannot afford anywhere near this. If the cost falls solely on the rich world, the price-tag adds up to almost $30,000 (CAD) per person, per year, over the century.

Canada has made a legal commitment to achieve “net zero” carbon emissions by 2050. Back in 2015, then-Prime Minister Trudeau promised that climate action will “create jobs and economic growth” and the federal government insists it will create a “strong economy.” The truth is that the net zero policy generates vast costs and very little benefit—and Canada would be better off changing direction.

Achieving net zero carbon emissions is far more daunting than politicians have ever admitted. Canada is nowhere near on track. Annual Canadian CO₂ emissions have increased 20 per cent since 1990. In the time that Trudeau was prime minister, fossil fuel energy supply actually increased over 11 per cent. Similarly, the share of fossil fuels in Canada’s total energy supply (not just electricity) increased from 75 per cent in 2015 to 77 per cent in 2023.

Over the same period, the switch from coal to gas, and a tiny 0.4 percentage point increase in the energy from solar and wind, has reduced annual CO₂ emissions by less than three per cent. On that trend, getting to zero won’t take 25 years as the Liberal government promised, but more than 160 years. One study shows that the government’s current plan which won’t even reach net-zero will cost Canada a quarter of a million jobs, seven per cent lower GDP and wages on average $8,000 lower.

Globally, achieving net-zero will be even harder. Remember, Canada makes up about 1.5 per cent of global CO₂ emissions, and while Canada is already rich with plenty of energy, the world’s poor want much more energy.

In order to achieve global net-zero by 2050, by 2030 we would already need to achieve the equivalent of removing the combined emissions of China and the United States — every year. This is in the realm of science fiction.

The painful Covid lockdowns of 2020 only reduced global emissions by about six per cent. To achieve net zero, the UN points out that we would need to have doubled those reductions in 2021, tripled them in 2022, quadrupled them in 2023, and so on. This year they would need to be sextupled, and by 2030 increased 11-fold. So far, the world hasn’t even managed to start reducing global carbon emissions, which last year hit a new record.

Data from both the International Energy Agency and the US Energy Information Administration give added cause for skepticism. Both organizations foresee the world getting more energy from renewables: an increase from today’s 16 per cent to between one-quarter to one-third of all primary energy by 2050. But that is far from a transition. On an optimistically linear trend, this means we’re a century or two away from achieving 100 percent renewables.

Politicians like to blithely suggest the shift away from fossil fuels isn’t unprecedented, because in the past we transitioned from wood to coal, from coal to oil, and from oil to gas. The truth is, humanity hasn’t made a real energy transition even once. Coal didn’t replace wood but mostly added to global energy, just like oil and gas have added further additional energy. As in the past, solar and wind are now mostly adding to our global energy output, rather than replacing fossil fuels.

Indeed, it’s worth remembering that even after two centuries, humanity’s transition away from wood is not over. More than two billion mostly poor people still depend on wood for cooking and heating, and it still provides about 5 per cent of global energy.

Like Canada, the world remains fossil fuel-based, as it delivers more than four-fifths of energy. Over the last half century, our dependence has declined only slightly from 87 per cent to 82 per cent, but in absolute terms we have increased our fossil fuel use by more than 150 per cent. On the trajectory since 1971, we will reach zero fossil fuel use some nine centuries from now, and even the fastest period of recent decline from 2014 would see us taking over three centuries.

Global warming will create more problems than benefits, so achieving net-zero would see real benefits. Over the century, the average person would experience benefits worth $700 (CAD) each year.

But net zero policies will be much more expensive. The best academic estimates show that over the century, policies to achieve net zero would cost every person on Earth the equivalent of more than CAD $4,000 every year. Of course, most people in poor countries cannot afford anywhere near this. If the cost falls solely on the rich world, the price-tag adds up to almost $30,000 (CAD) per person, per year, over the century.

Every year over the 21st century, costs would vastly outweigh benefits, and global costs would exceed benefits by over CAD 32 trillion each year.

We would see much higher transport costs, higher electricity costs, higher heating and cooling costs and — as businesses would also have to pay for all this — drastic increases in the price of food and all other necessities. Just one example: net-zero targets would likely increase gas costs some two-to-four times even by 2030, costing consumers up to $US52.6 trillion. All that makes it a policy that just doesn’t make sense—for Canada and for the world.

The stupidity of Net Zero | Bjorn Lomborg on how climate alarmism leads to economic crisis

Published on

From spiked on YouTube

Note: This interview is focused on Europe and the UK.  It very much applies to Canada. The 2025 Federal Election which will see Canadians choose between a more common sense approach, and spending the next 4 years continuing down the path of pursuing “The Stupidity of Net Zero”.

European industry is in freefall, and Net Zero is to blame.

Here, climate economist Bjorn Lomborg – author of Best Things First and False Alarm – explains how panic over climate change is doing far more damage than climate change itself.  Swapping cheap and dependable fossil fuels for unreliable and expensive renewables costs our economies trillions, but for little environmental gain, Lomborg says.

Plus, he tackles the myth of the ‘climate apocalypse’ and explains why there are more polar bears than ever.
