Introduction

What’s in it for me? Learn what needs to be done in order to make the planet emission-free by 2050.

Bill Gates has spent a lot of time listening to people talk about climate change, and he’s spent millions of dollars investing in solutions that, at one point or another, have sounded promising. Some of that money has vanished along with the collapse of various projects and startups; other initiatives are still experimenting, with encouraging results. Suffice it to say, he’s learned a thing or two about what’s at stake – and about the kind of work that still needs to be done if we’re going to save our planet.

Convinced by the testimonials of experts and his own extensive research, Gates has a bottom line: we need to get to zero emissions by 2050. He knows this is a big ask. We’ve gotten used to doing things a certain way, and it’s going to take some difficult changes in order to reach this important goal. Ultimately, it’s something we must do, and with the right kind of innovation and cooperation, we can get there.

In these blinks, you’ll learn

the five categories responsible for greenhouse gas emissions;
why there are limits to electrically powered transportation; and
why investing in climate disaster prevention is smart money.

To bring our planet back from the brink of disaster, we need to get our greenhouse gas emissions to zero.

When Bill Gates and Paul Allen founded Microsoft in 1975, they were living in Albuquerque, New Mexico. Back then, the city was already pretty hot; temperatures climbed to over 90 degrees Fahrenheit an average of 36 days a year. But by 2050, that number of days is expected to double. And by the end of the century, it will triple. The health and economic consequences will be profound.

The reason for this rapid increase in temperature is that we’re currently pumping around 51 billion tons of greenhouse gases into the atmosphere every year. And while efforts are underway to improve the situation, this number isn’t going down; in fact, it’s only getting bigger.

The key message here is: To bring our planet back from the brink of disaster, we need to get our greenhouse gas emissions to zero.

So what can we do? Well, to start, we need to understand what greenhouse gases are and how they work.

There are many different greenhouse gases, including carbon dioxide, methane, and nitrous oxide. Some are more harmful than others, but carbon dioxide alone accounts for more than 70 percent of yearly emissions. So, to keep the numbers simple, the collective term “greenhouse gases” also goes by the more scientific name of carbon dioxide equivalents – and this is the 51 billion tons that we’re dealing with.

The term “greenhouse gases” does a pretty good job of describing the problem these gases cause. They let the sun’s energy in, but they don’t let the resulting heat escape once it’s bounced back off the earth’s surface. As a result, the heat is trapped, much like the heat inside a greenhouse. It’s the same process that makes the inside of your car hotter than the outside on a sunny, summer afternoon.

The effect of these greenhouse gases is that the planet has gotten hotter. Since the dawn of the Industrial Age, the average global temperature has risen one degree Celsius; some areas have even experienced a rise of over two degrees. That may not sound like much, but, on a global scale, it is. And there are many far-reaching consequences.

For example, increased temperatures cause more moisture from the earth’s surface to evaporate into the atmosphere. As a result, there are more droughts around the world, more wildfires, and more flooding in areas already in danger of being consumed by water. Already, 20 to 30 percent of Bangladesh is underwater on a regular basis. This problem will only get worse – and more common around the world. This means more displaced people, as well as fewer habitats for both plants and animals.

We need to get to zero emissions because every second we don’t, the situation gets worse. Greenhouse gases don’t vanish overnight. They stick around for tens of thousands of years. Think of it like a bathtub on the verge of overflowing. Even a small but steady drip will cause the water to start spilling over.

Getting to zero emissions will be difficult, but it can and must be done.

Getting to zero won’t be easy. Harmful emissions are caused by many things that we’ve come to take for granted. Electricity, heating, transportation, large-scale agriculture, and fundamental construction tools like iron and cement – all of these areas will require serious rethinking if we’re to reach the goal.

What’s more, many areas of the world are just now getting more industrialized. Economies are booming. Overall, this is good news. It means more people are being lifted out of poverty and becoming wealthier. But as these countries begin to take steps toward improving their infrastructure and building thriving cities, they’re picking up the same tools of industrialization that have led us to our current climate crisis.

Getting electricity to zero will take some major innovations.

Electricity is a good place to start because it affects all the other categories. Right now, two-thirds of the world’s electricity is supplied by burning fossil fuels. Getting this ratio down to zero will naturally have a major impact on how we make things, grow things, get around, and so on – things like factories, agriculture, and cars will all require clean electricity to function.

The key message here is: Getting electricity to zero will take some major innovations.

Producing steel, concrete, and plastic creates greenhouse gas emissions – but there may be a silver lining.

Let’s move on to how we make things, which accounts for about a third of the world’s 51 billion tons of greenhouse gas emissions. Things like steel and concrete are being produced in abundance around the world, resulting in great amounts of harmful emissions. And this will only increase as more countries become more prosperous. Between 2000 and 2016, for instance, China used more concrete than the US did during the entire twentieth century.

We can reduce food industry emissions by living more consciously.

You may be surprised to learn that our food practices account for more harmful emissions than our transportation practices. But at 19 percent of the annual 51 billion tons of greenhouse gases, how we grow things comes in third. This shows that harmful emission can come in unexpected ways.

For example, you may know that cattle produce a lot of methane, one of the most harmful greenhouse gases in terms of contributing to warming temperatures. But did you know that throwing away food is also a significant contributor? When food rots, it also produces methane. And we throw away lots of food every year – the equivalent of 3.3 billion tons of carbon dioxide, to be exact.

Sustainable transportation options include clean fuels that come with big prices.

In terms of cost, we can consider Green Premiums to understand exactly what needs to change to reduce our emissions. Green Premiums essentially highlight the cost differences between current practices and the clean practices that will get us to zero.

For example, a ton of concrete currently costs around $125 to make. Using carbon capture technology, that cost would be somewhere between $219 and $300. That means the Green Premium, at its highest, is a 140 percent increase. This difference shows that carbon capture technology needs more funding and research in order to become an economically viable option.

There are immediate steps we can take to reduce heating and cooling emissions.

As people around the world become wealthier, they’ll travel more, buy more food, and live in homes equipped with heating and air conditioning. Right now, worldwide, there are 1.6 billion air conditioning units in use. Most of these are in rich countries, not in the hottest places in the world. By 2050, that number is expected to rise to 5 billion.

Currently, heating and air conditioning account for 7 percent of the 51 billion tons of greenhouse gas emissions. But, as we can see, that number will likely rise in the near future. Already, in places like Mexico, Brazil, Indonesia, and India, sales for AC units have risen sharply in just the past few years.

Getting to zero will require changes in government policy and international cooperation.

As you’ve gathered, there are a lot of steps standing in our way to zero emissions. But there’s also a lot of work to do to adapt and prepare ourselves for the climate change that’s already underway. We need to create better early warning systems for impending floods, storm surges, and rising water levels. We also need to start building more energy efficient homes and updating our infrastructure to accommodate clean energy.

If you think all this will cost a lot, you’re right. But it will also pay off in big ways. Estimates suggest that investing $1.8 trillion into climate disaster prevention will yield $7 trillion in benefits over a period of just ten years. That’s smart money. But, as you may already suspect, it’s going to take some government support – on an international level.
