The Briefing

Olympics 2021: Comparing Every Sports Ball

It might be strange having the Olympics in 2021 (an odd year), but 2020 was anything but normal.

After facing a 12-month delay due to the COVID-19 pandemic, the 2020 Summer Olympics in Tokyo are set to kick off from July 23 to August 8.

In addition to hosting traditional sports like running and aquatics, some sports are being introduced for the first time (karate, skateboarding) or returning after an absence (baseball).

One thing that many Olympic sports share in common? There are 17 different sports that use balls or spheres of some sort, ranging in size and weight. Here are the different balls used in the Tokyo Olympics.

Olympic Sports Balls by Size and Weight

The 2021 Olympics, which are still officially called the 2020 Olympics to keep the four-year cycle and branding consistent, are hosting 339 events across 33 different sports.

17 of those sports use balls or spheres. The official sizes and weights vary from a small diameter of 4cm for table tennis to the largest ball, a basketball with a diameter of 24.35cm.

Water Polo (Women’s)21.01cm425g

Water Polo (Men’s)22.28cm425g
Basketball (Women’s)23.24cm538g
Basketball (Men’s)24.35cm608g

Even within the same categories of sports, balls have different size and weight rules based on event or gender. Water polo, handball, and basketball all have slight variations of a few centimeters in diameter and up to 100g in weight for different gender events.

But sorting the balls by weight shows that the shot is far and away the heaviest. At 7.26kg, the shot is more than 10 times heavier than a basketball. That’s because while most sporting balls are made of light material filled with air, shots are typically constructed entirely of metal.

Can You Calculate Your Daily Carbon Footprint?

Discover how the average person’s carbon footprint impacts the environment and learn how carbon credits can offset your carbon footprint.

The Briefing

  • A person’s carbon footprint is substantial, with activities such as food consumption creating as much as 4,500 g of CO₂ emissions daily.
  • By purchasing carbon credits from Carbon Streaming Corporation, you can offset your own emissions and fund positive climate action.

Your Everyday Carbon Footprint

While many large businesses and countries have committed to net-zero goals, it is essential to acknowledge that your everyday activities also contribute to global emissions.

In this graphic, sponsored by Carbon Streaming Corporation, we will explore how the choices we make and the products we use have a profound impact on our carbon footprint.

Carbon Emissions by Activity

Here are some of the daily activities and products of the average person and their carbon footprint, according to Clever Carbon.

Household Activities & ProductsCO2 Emissions (g)
💡 Standard Light Bulb (100 watts, four hours)172 g
📱 Mobile Phone Use (195 minutes per day)*189 g
👕 Washing Machine (0.63 kWh)275 g
🔥 Electric Oven (1.56 kWh)675 g
♨️ Tumble Dryer (2.5 kWh)1,000 g
🧻 Toilet Roll (2 ply)1,300 g
🚿 Hot Shower (10 mins)2,000 g
🚙 Daily Commute (one hour, by car)3,360 g
🍽️ Average Daily Food Consumption (three meals of 600 calories)4,500 g
*Phone use based on yearly use of 69kg per the source, Reboxed

Your choice of transportation plays a crucial role in determining your carbon footprint. For instance, a 15 km daily commute to work on public transport generates an average of 1,464 g of CO₂ emissions. Compared to 3,360 g—twice the volume for a journey the same length by car.

By opting for more sustainable modes of transport, such as cycling, walking, or public transportation, you can significantly reduce your carbon footprint.

Addressing Your Carbon Footprint

One way to compensate for your emissions is by purchasing high-quality carbon credits. 

Carbon credits are used to help fund projects that avoid, reduce or remove CO₂ emissions. This includes nature-based solutions such as reforestation and improved forest management, or technology-based solutions such as the production of biochar and carbon capture and storage (CCS).

While carbon credits offer a potential solution for individuals to help reduce global emissions, public awareness remains a significant challenge. A BCG-Patch survey revealed that only 34% of U.S. consumers are familiar with carbon credits, and only 3% have purchased them in the past.

About Carbon Streaming

By financing the creation or expansion of carbon projects, Carbon Streaming Corporation secures the rights to future carbon credits generated by these sustainable projects. You can then purchase these carbon credits to help fund climate solutions around the world and compensate for your own emissions.
