Air pollution is no match for all of us, working together.
All the solutions listed here are already happening around the world because people came together and demanded it.
Air pollution is harming many of us around the world. Many of us are breathing air that is damaging almost every organ in our body. Worse, one of the main causes of air pollution—burning fossil fuels —also causes climate change that is endangering all of us by heating the planet on which we depend.
Air pollution is indeed a crisis, but it’s a crisis we can solve—and around the world, people are solving it! Here’s what that looks like.
Burning all fossil fuels is bad, but coal is the worst. When burnt, it releases more carbon dioxide (CO2) per unit of energy than oil or gas – which means it heats up our planet faster.
Coal is toxic, too. Burning it releases elements like mercury and arsenic and small particles of soot that contribute to air pollution. When we breathe it in, that soot harms our heart and lungs and even increases our risk of strokes.
But the worst thing about coal is how widespread it is. Coal provides more than a third of the world’s electricity. That’s more than any other single source! These power plants affect air quality for hundreds of kilometers—and are often placed right in the heart of cities, so millions of people get little respite from the pollution these plants cause.
We desperately need to wean ourselves off coal and get our power from clean sources like wind, sun, and tides. Some counties have started. In 2019, coal power had its biggest slump ever recorded! But we need every country in the world to move much faster towards renewable energy. Greenpeace International has even mapped out how they could go about it.
Most cars run on gas, and just like burning coal, burning oil comes with a huge environmental price tag. Petrol and diesel cars emit CO2 and other gases that heat our planet. On top of other nasties, the exhaust fumes these cars produce contain Nitrogen Dioxide (NO2), which is another pollutant that harms our health.
But there are other ways we can move around, and leave the car behind.
Cities around the world are waking up to the joys of car-free travel. From pedestrian zones to proper public infrastructure to comprehensive and affordable public transport, there are so many ways cities can help us go car-free more often. And the benefits are many: more space, cleaner air, and a more active, healthy population.
But for those journeys that still need cars, we should start thinking about cars very differently. Rather than gas, we should power cars with electricity. Electric cars are zero-emissions ‘at the pipe’, meaning the cars themselves don’t emit any exhaust fumes. Almost all their emissions come from their manufacture and in producing the electricity that powers them. If that electricity is renewable, those emissions are essentially zero. But even in coal-heavy (carbon-intensive) grid-like Poland, it’s still a substantial cut in emissions compared with conventional cars. The pollution savings multiply even more when cars are made smaller, so they use less energy to make and move, and for sharing rather than private ownership, so we can all get by with fewer of them.
Concerns about air pollution made Shenzhen, China electrify its bus fleet. Parents in Belgium mobilized because the air in schools was so dirty. Now, Brussels, its capital city, is banning petrol and diesel cars from 2030 and investing in public transport and cycling infrastructure. And around the world, concerns about the climate impacts of coal are causing governments to look into new ways of getting their power; Turkey has closed five coal power plants in 2020 alone!
