Today’s young people are coming of age just as the stable climate that has allowed previous generations to thrive on our planet begins to visibly break down—and just before our last chance to stop it falls out of reach._ by [Yuval Noah Harari](https://time.com/author/yuval-noah-harari/) ## Yuval Noah Harari  Illustration by Aldo Crusher for TIME A**s the climate crisis worsens,** too many people are swinging from denial straight to despair. A few years ago, it was common to hear people deny climate change, downplay the enormousness of the threat, or argue that it is far too soon to worry about it. Now many people say it’s too late. The apocalypse is coming, and there is nothing we can do to prevent it. Despair is as dangerous as denial. And it is equally false. Humanity has enormous resources under its command, and by applying them wisely, we can still prevent ecological cataclysm. But exactly how much would it [cost](https://time.com/6131659/climate-disaster-extreme-weather-cost/) to stop the apocalypse? If humankind wanted to prevent [catastrophic climate change](https://time.com/5953374/climate-is-everything/), how big a check would we have to write? Naturally enough, no one knows for sure. My team and I have spent weeks poring over various reports and academic papers, living in a cloud of numbers. But while the models behind the numbers are dizzyingly complex, the bottom line should cheer us up. According to the [International Energy Agency](https://time.com/6049584/climate-change-iea-report/), achieving a net-zero carbon economy would require us to spend just 2% of annual global GDP over what we already do on our [energy system](https://iea.blob.core.windows.net/assets/ad0d4830-bd7e-47b6-838c-40d115733c13/NetZeroby2050-ARoadmapfortheGlobalEnergySector.pdf). In a recent poll of climate economists conducted by Reuters, most agreed that getting to net zero would cost only 2% to 3% of [annual global GDP](https://www.reuters.com/business/cop/climate-inaction-costlier-than-net-zero-transition-economists-2021-10-25/). Other estimates put the cost of decarbonizing the economy a bit [lower](https://www.weforum.org/agenda/2020/11/how-world-get-to-net-zero-carbon/) or a bit [higher](https://irena.org/newsroom/pressreleases/2021/Jun/IRENAs-World-Energy-Transitions-Outlook-Re-Writes-Energy-Narrative-for-a-Net-Zero-World), but they are all in the low single digits of annual global GDP. These numbers echo the assessment of the Intergovernmental Panel on Climate Change, which in its landmark [2018 report](https://time.com/5418134/ipcc-climate-change-report-2030-crisis/) stated that in order to limit climate change to 1.5°C, annual investments in clean energy needed to increase to around 3% of global GDP. Since humankind already spends about 1% of annual global GDP on clean energy, we just need an extra [2% slice](https://www.ipcc.ch/site/assets/uploads/sites/2/2019/05/SR15%5FChapter2%5FLow%5FRes.pdf) of the pie! The above calculations focus on the cost of transforming the energy and transportation sectors, which are by far the most important. However, there are other sources of emissions as well, like land use, forestry and agriculture. You know, those infamous cow farts. The good news is that a lot of these emissions can be cut on the cheap through behavioral changes such as [reducing meat and dairy consumption](https://time.com/5648082/un-climate-report-less-meat/) and relying more on a [plant-based diet](https://www.nature.com/articles/d41586-019-02409-7). It doesn’t cost anything to [eat more veggies](https://time.com/4266874/vegetarian-diet-climate-change/), and it can help you (and the rain forests) [live longer](https://doi.org/10.1016/j.tem.2019.04.001). **Read more:** [**_Why We Must Revolutionize Food Systems to Save Our Planet_**](https://time.com/6102967/food-systems-climate-change/) We can quibble endlessly about the numbers, tweaking the models this way and that. But we should look at the big picture beyond the math. The crucial news is that the price tag of preventing the apocalypse is in the low single digits of annual global GDP. It is certainly not 50% of annual global GDP, nor is it 15%. Rather, it is somewhere below 5%, perhaps as low as investing an additional 2% of global GDP in the right places. And note the word investing. We aren’t talking about burning piles of banknotes in some huge sacrifice to the spirits of the earth. We are talking about making investments in new technologies and infrastructure, such as advanced batteries to store solar energy and updated power grids to distribute it. These investments will create numerous new jobs and economic opportunities, and are likely to be economically profitable in the [long run](https://pubmed.ncbi.nlm.nih.gov/29795251/) in part by reducing health care expenditures and saving millions of people from sickness caused by[ air pollution](https://www.pnas.org/content/118/46/e2104061118). We can protect the most vulnerable populations from climate disasters, become better ancestors to future generations, and create a more prosperous economy in the process. This wonderful piece of news has somehow been sidelined in the heated debate about [climate change](https://time.com/6088531/ipcc-climate-report-hockey-stick-curve/). We should bring it into focus, not merely in order to give people hope, but even more so because it can be translated into a concrete political plan of action. We have learned in recent years to define our goal in terms of one number: 1.5°C. We can define the means to do this with another number: 2%. Increase investment in eco-friendly technologies and infrastructure by 2 percentage points above 2020 levels. Of course, unlike the 1.5°C figure, which is a scientifically robust threshold, the 2% figure represents only a rough guesstimate. It should be understood as a ballpark figure, helpful to frame the kind of political project humanity requires. It tells us that preventing catastrophic climate change is a totally feasible project, even though it would obviously cost a lot of money. Since global GDP is now about $85 trillion USD, 2% currently totals about $1.7 trillion. It means that to save the environment, we don’t need to completely derail the economy or abandon the achievements of modern civilization. We just need to get our priorities right. **Read mor** **e:** [**_Climate Crises Dominated 2021\. But These Innovations Offer Some Hope_**](https://time.com/6127792/year-in-climate-innovation-2021/) **Signing a check** for 2% of annual global GDP is far from the whole story. It won’t solve all our ecological problems, such as oceans brimming with plastic or the continued loss of biodiversity. And even to prevent catastrophic climate change, we’ll need to make sure that the funds are invested in the right places and that the new investments don’t cause their own negative ecological or social fallout. If we destroy ecosystems to mine for rare metals that are needed for the renewables industry, we might arguably lose as much as we gain. We will also need to change some of our behaviors and ways of thinking, from what we eat to how we travel. None of that will be easy. But that’s exactly why we have politicians—their job is to deal with the hard stuff. Politicians are actually very skilled at shifting 2% of resources from here to there. It is what they do all the time. The difference between the policies of right-wing and left-wing parties often amount to a few percentage points of GDP. When faced by a major crisis, politicians swiftly shift far more resources to fight it. For example, in 1945, the U.S. spent about 36% of its GDP on winning the[ Second World War](https://www.nytimes.com/2010/07/25/weekinreview/25bumiller.html). During the 2008–09 financial crisis, the U.S. government spent about 3.5% of GDP to save financial institutions deemed [“too big to fail.”](https://mitsloan.mit.edu/ideas-made-to-matter/heres-how-much-2008-bailouts-really-cost) Maybe humankind should also treat the Amazon rain forest as “too big to fail”? Given the current price of rain-forest land in South America and the size of the Amazon rain forest, buying the whole of it in order to protect local forests, biodiversity and human communities from destructive business interests would cost about $800 billion, or a one-off payment of less than [1% of global GDP](https://publications.iadb.org/publications/english/document/Latin-American-and-Caribbean-Forests-in-the-2020s-Trends-Challenges-and-Opportunities.pdf.). In just the first nine months of 2020, governments around the world announced stimulus measures worth nearly 14% of global GDP to deal with the [COVID-19 pandemic](https://www.imf.org/external/pubs/ft/ar/2020/eng/downloads/imf-annual-report-2020.pdf). If citizens press them hard enough, politicians can do the same to deal with the ecological crisis. So can investment [banks](https://time.com/6109448/world-economy-climate-change/) and pension funds. Pension funds hold about [$56 trillion USD](http://: https://www.thinkingaheadinstitute.org/research-papers/global-pension-assets-study-2021/#:%7E:text=The%20Global%20Pension%20Assets%20Study,the%20GDP%20of%20these%20economies). What’s the point of having a pension if you don’t have a future? **At present, neither businesses** nor governments are willing to make the additional 2% investment necessary to prevent catastrophic climate change. Where does the money go instead? In 2020, governments expended $2 trillion USD on their [militaries](https://www.sipri.org/media/press-release/2021/world-military-spending-rises-almost-2-trillion-2020)—that’s 2.4% of global GDP. Every two years, another 2.4% of global GDP is spent on food that goes to [waste](http://https://www.wfpusa.org/articles/8-facts-to-know-about-food-waste-and-hunger/). Governments also spend about $500 billion annually on—wait for it—direct subsidies for fossil fuels! Which means that every 3½ years, governments write a nice fat check for an amount equivalent to 2% of annual global GDP, and gift it to the [fossil-fuel industry](https://www.nature.com/articles/d41586-021-02847-2). It gets worse. When you factor in the social and environmental costs that the fossil-fuel industry causes but isn’t asked to pay for, then the value of these subsidies actually reaches a staggering 7% of annual [global GDP](https://www.nature.com/articles/d41586-021-02847-2) each year. Now consider [tax evasion](https://time.com/5954786/irs-tax-enforcement/). The E.U. estimates that money hidden by the wealthy in tax havens is worth around 10% of [global GDP](https://op.europa.eu/en/publication-detail/-/publication/10854d45-f549-11e9-8c1f-01aa75ed71a1). Every year, another $1.4 trillion in profits is stashed offshore by corporations, which is equal to [1.6% of global GDP](https://www.washingtonpost.com/us-policy/2020/11/19/global-tax-evasion-data/). To prevent the apocalypse, we’ll probably need to impose some new taxes. But why not start with collecting the old ones? The money is there. Of course, collecting taxes, cutting military budgets, stopping food wastage and slashing subsidies is easier said than done, especially when faced by some of the most powerful lobbies in the world. But it doesn’t require a miracle. It just requires determined organization. So we shouldn’t succumb to defeatism. Whenever someone says, “It’s too late! The apocalypse is upon us!,” reply, “Nah, we can stop it with just 2%.” And when COP27 convenes in November 2022 in Egypt, we should tell the assembled leaders that it is not enough to make vague future pledges about 1.5°C. We want them to take out their pens and sign a check for 2% of annual global GDP.  _Harari is the author of_ [Sapiens, Homo Deus and Sapiens: A Graphic History](https://bookshop.org/books/sapiens-a-brief-history-of-humankind-9781467601573/9780062316110). _Data sources for this article can be found on_ [_bit.ly/2-percent-more_](https://www.sapienship.co/decision-makers/2-percent-more) ## Transcript [Namrata Iyer]: I think some of the biggest challenges my generation faces is convincing the previous generations about why it's important to talk about what we believe in. [Greta Thunberg]: We can't choose between us young people saying to adults you must behave but we can't wait for us to become the ones in charge because we don't have time for that. [Timothée Chalamet]: Your youth does not have to work against you by way of experience, your youth can be a virtue by way of what you ethically and earnestly expect of the world. [Billie Eilish]: People can be so selfish about the environment and their experience versus the globe and literally our lifespan. [Alexandria Ocasio-Cortez]: The America we grew up in is like nothing like the America our parents or grandparents grew up in. [Nyke Slawik]: When you have young people who are confronted with not having a future at all of course this is going to radicalize a whole generation. This is a question of survival basically. [John Kerry]: I don't doubt that we will get to a net zero carbon economy. Will we get there fast enough to heed the science and avoid the worst consequences? That's the battle. That's what we're trying to do with Glasgow. [Thunberg]: What do we want? [Audience]: Climate justice. [Thunberg]: When do we want it? [Audience]: Now. [Thunberg]: What do we want? [Audience]: Climate justice. [Thunberg]: When do we want it? [Audience]: Now. [Thunberg]: Thank you. [Justin Worland]: This generation has reframed the way we talk and think about climate to make it an issue of intergenerational justice. The question is will this anger turn into action? Will leaders who have been listening actually take the message to heart and do something about it? [Kerry]: Our diplomacy is guided by what the scientists are telling us we must achieve. Three years ago they had a report in 2018 the IPCC gave us 12 years within which to make the critical decisions to avoid the worst consequences of the climate crisis. [Hoesung Lee]: Limiting warming to 1.5 degrees is not impossible but will require unprecedented transitions in all aspects of society. [Worland]: It was alarming in its the seriousness with which it portrayed the consequences of climate change. We're talking about hundreds of millions of people migrating. We're talking about the possibility of countries disappearing in their entirety. We're talking about a world that is totally transformed. Already 85 percent of the world's population has been affected by human-caused climate change. [Jim Skea]: The message is over to governments at this stage. We've told you what you—the scientific facts, the evidence, the costs. It is up to the governments now to decide what to do with it. [Ciara Nugent]: We've had loads and loads of reports about climate change over the last couple of decades and the massive threat to our planet but despite all of the science there are still people who are skeptical about how much of a big deal it really is. And I think for those people it's much harder to dismiss young people, normal school kids because they're part of their communities, they're part of their families often. [Nyke Slawik]: What we need is politicians who implement the policies in their home countries and that's—that's what has not been happening in the last years. And so now young people are saying why go to school? Why go to university? Why start planning a family? Why buy a house when I don't even know that in 50 years time or 70 years time I will still have a future, because right now that's at stake. [Ocasio-Cortez]: If we do nothing this is what's going to happen: sea levels are going rise, crops are going to die out, there will be mass starvation. There's going to be all of these things that are going to happen and kids see that, they internalize it. [Charlotte Alter]: Researchers have found that young voters form their lifelong political attitudes in response to the events of their early adulthood, mostly late teens into the late 20s. And for millennials and gen z that period of time has been defined by climate catastrophe. [Christian Hidalgo]: I'm from Bakersfield, California, central valley. Earlier today I've been getting snapchats from all of my friends talking about how orange the sky is because of the wildfire surrounding us. The closest wildfire is probably not even 60 miles away but we have horrible air quality like we're—I'm in the middle of the valley and it just it really strongly affects us and that's what—that's what's drawn me to climate activism. [Isabella Guariniello]: This is my first strike ever. I watched a bunch of like sad penguin videos on YouTube and I started to get really sad when I learned about the effects of animals and like how much earth that we're actually losing. It's hard not to get discouraged when you're constantly learning about what people before you did wrong. [Sassy Fernandez]: Like I remember being in elementary school and watching Al Gore's documentary about climate change and the effects that we could be seeing within the next 10, 15 years and so far he's been pretty right about everything that he said in his documentary. I totally forgot what it was called but shout outs to my science teacher. [Thunberg]: We are being betrayed by those in power and they are failing us but we will not back down. And if you feel threatened by that then I have some very bad news for you. We will not be silenced because we are the change and change is coming whether you like it or not. We need to work together intergenerational of course that is the only way and we need to—everyone needs to participate and help out in the way we can. So I'm doing what I can. I'm trying to use my voice to spread awareness and to—to put pressure on those in power. [Alter]: When TIME put Greta on the cover in 2019 she had just gone from being a school girl protesting alone outside of Swedish parliament to being the leader of a global climate movement. That year her activism inspired four million people to join the global climate strike in 2019 which was at that point the largest climate movement in world history. [Worland]: Across the world with very few exceptions there are examples of people who have been inspired by her and have led—who've taken up the mantle the Fridays for Future movement in countries across the world. [Thunberg]: I'm not a leader or the face of the climate movement, I'm just one of many faces. [Vanessa Nakate]: There are far too little evidence of the 100 billion dollars per year that was promised to help climate vulnerable countries to meet these challenges. In fact, those funds were promised to arrive by 2020 and we are still waiting. [Nugent]: Vanessa Nakate, a Ugandan climate activist, is one of many people who have been working to remind us that climate action is going to be expensive and many countries who are most vulnerable to climate change can't afford to pay for it alone. [Nakate]: Historically Africa is responsible for only three percent of global emissions and yet some Africans are already suffering some of the worst and brutal impacts of climate change, so to me climate justice doesn't just have to be about reducing greenhouse gas emissions it goes beyond the primary disasters that we see. It is what happens in the aftermath of those disasters, what happens to families, what happens to individuals, what happens to communities. [Worland]: You think about the fact that the U.S. has emitted a quarter of emissions historically. Africa has emitted three percent of emissions historically and the U.S. is able to isolate itself, to pay for adaptation, to pay for the costs in a way that developing countries in sub-saharan Africa and across the globe just can't. And so climate change is a justice issue on many different levels. [Ngozi Okonjo-Iweala]: We we have to bear in mind that whether you're rich or poor, a rich country or poor country, there are some things you just cannot do on your own. You can't deliver on this pandemic on your own, you cannot deliver on climate change on your own. [Nakate]: So what we really want is a future that is healthy, that is sustainable, that is clean, that is livable and equitable for all of us. [Nugent]: Some of the activists that I speak to are realizing they can't wait for the older generation to take action so they're trying to get elected to governments themselves. In Germany, the Green Party has really been in the ascendancy. In September they've almost doubled their number of seats in parliament and one of the 118 lawmakers they now have is Nyke Slawik. She's a 27 year old German politician who was elected in September to the Bundestag and she has been involved in climate activism for almost 12 years and now she has political power to make a difference. [Slawik]: The time of just implementing small changes has passed and this is a reality we as younger politicians are bringing with us to the parliament now but of course there's lots of older colleagues who have not quite grasped this yet, and I think this is why we might be more determined to not go for the small compromises, to be a bit more rebellious about these things. The last German government has decided to exit coal in 2038 which is still too late way too late but now we even have the chance to accelerate energy transition from coal to renewables way quicker and that's a major achievement of the youth climate movement. [Alter]: In the United States young voters across the political spectrum understand that climate change is a major issue that needs to be addressed, they just disagree on how best to do it. So even younger Republicans, Republicans under 40, they understand that climate change is happening, they understand that something has to be done about it, they just don't agree with their more progressive peers about the scale and scope of what that intervention needs to be. So this is a big shift from a couple generations ago when you had one side insisting that climate change was a problem and the other side basically denying that it was happening at all. [Worland]: When TIME spoke to Emmanuel Macron, the President of France, he spoke about how the youth movement had made him want to do better. When I talked to the U.N. Secretary General he talked about how he was trying to bring youth into the climate discussion because it had enthused him and he thought it would help change the conversation. Talking to members of Congress about how inspirational Greta was really made clear to me that she was changing the conversation. [Nugent]: In my reporting activists are telling me that COP 26 is a crucial moment to find out if politicians are really listening to them and really taking action or if they're just saying they're listening and delaying action. [Nakate]: Leaders keep praising young people for standing up and protesting but saving the world needs action, it needs decisions from the leaders, decisions that prioritize the lives of the people and the planet, and that is not something that we are doing. The words of the leaders are not matching up with their actions. [Thunberg]: Words. Words that sound great but so far has led to no action. Our hopes and dreams drown in their empty words and promises. Of course we need constructive dialogue but they've now had 30 years of blah blah blah and where has that led us? [Jane Goodall]: I'm about to leave the world and leave it behind me with all the mess whereas young people have to grow up into it. That's why they need every bit of help they can. And if, you know, if they succumb to the doom and gloom ,which many have, then they lose hope. If you lose hope that's the end, because if you don't hope that there's a way out, if you don't hope that your actions can make a difference then you sink into apathy and do nothing. So hope is absolutely crucial if we're to get through this. [Singing]: We're going to strike because our waters are rising. We're going to strike because our people are dying. We're going to strike for life and everything we love. We're going to strike for you, will you strike for us? We're going to strike for you, will you strike for us? We're going to strike because our waters are rising. We're going to strike because our people are dying. We're going to strike for life and everything we love. We're going to strike for you, will you strike for us? We're going to strike for you, will you strike for us? Beautiful. ```json [{"@context":"https://schema.org","@type":"Article","@id":"https://time.com/collections/power-of-collaboration/6132395/two-percent-climate-solution/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/collections/power-of-collaboration/6132395/two-percent-climate-solution/"},"headline":"The Surprisingly Low Price Tag on Preventing Climate Disaster","datePublished":"2022-01-18T11:55:14.000Z","dateModified":"2026-08-04T07:24:28.830Z","description":"Exactly how much would it cost to stop the climate apocalypse?
