Statistics Behind World Carbon Dioxide Emissions

Chris over at Fly.co.uk recently informed me of an infographic on their website. The infographic shows some interesting statistics on world carbon dioxide emissions.

For example, according to the infographic, in 2009, China produced 6,200 million tonnes of CO2 compared to 5,800 for the United States. One only needs to look at the population of these two countries to see that something appears to be out of whack.

China has over 4 times the population of the US and yet, the US emits almost as much CO2 as China. Unfortunately, this gap is bound to widen as China becomes more and more prosperous.

As one would expect, the infographic has an airline/transport spin (no doubt due to the fact that its on a flight website), so there are some interesting statistics in that area.

A copy of the infographic is below. Due to its size, I’ve resized it to fit on this blog.

10 Tips For Greater Fuel Economy

When assessing cars we usually consider if they are economical to run, but we should also consider how economical our own driving habits are. Indeed, by following the fuel economy tips below, you’ll be able to save on fuel and save the planet without having to change our used car to a brand new hybrid :

  1. Keep a steady average speed – avoid travelling at over 100km/h (65mph). When driving at higher speeds, your car uses most of the energy produced to combat the air resistance. As a result, your car’s fuel consumption is most effective at the speed of 50-90km/h (30-50mph), so it’s best to avoid over-accelerating wherever possible.
  2. Use the highest possible gear – most cars’ engines are more effective at lower revs, so make sure you change up as you accelerate to keep the revs down around 1,500 – 2,500rpm.
  3. Clean your car’s air filter regularly – driving your vehicle with a dirty filter can reduce its economy by 10 percent, as this restricts the air from reaching the engine.
  4. Make your car lose some weight Every extra 25kg makes your car consume 1 percent more fuel, so remove all the unnecessary items you’re carrying around, such as a roof box or bicycle rack, if you’re not going to use them in the near future.
  5. Predict the situation down the road – when you see red lights or traffic ahead, do not accelerate. Speeding unnecessarily and then braking rapidly burns more fuel than if you drove at a steady pace.
  6. Do not leave the engine idling – even when idling, an engine consumes fuel. So, if you’re stationary for more than 10 seconds, it’s more economical to stop the engine and then restart it when required.
  7. Close the windows – if driving at more than 50km/h (30mph) open windows increase the air resistance, which will be reflected in more frequent visits to the petrol station.
  8. Pump up your tyres – correct air pressure is essential for economical driving. What’s more, it’s easy to monitor and control your tyre pressure, as most petrol stations have a gauge and pump that drivers can use free of charge.
  9. Avoid overusing the air-conditioning – use your air-conditioning only when it’s necessary, as it can increase the fuel consumption by up to 10 percent.
  10. Ask yourself one simple question before each journey – ‘do I really need to go by car?’ For short hops, consider using a bike or walking from time to time, thereby cutting your fuel consumption and your carbon footprint.

You say “Hemcrete”, I say “Hempcrete”

I recently raved about the environmental benefits of hemp. I also compiled a list of various ways hemp is being used around the world. There’s no doubt to the versatility of this fiber.

One industry that is reaping the benefits of hemp is the building industry. Sustainable housing is becoming more and more important and hemp can certainly step up to the mark.

There are many applications of hemp in the building industry. It can be used for insulation, fiberboard, stucco and mortar and more. The use of hemp in the building industry has even sparked a new word – hempcrete.

What is Hempcrete?

Put simply, hempcrete is an eco-friendly alternative to concrete. It consists of a mixture of hemp, lime, sand, plaster, and cement, and can be used in the same way as concrete. Hempcrete is typically mixed on site, then sprayed on to the building frame. Hempcrete can also be used for making pipes.

Hempcrete is self insulating. It’s resistant to rotting, mice, rodents, etc. It is also fireproof, waterproof, and weather resistant.

Hempcrete actually has some pretty cool benefits over concrete too.

Benefits of Hempcrete

Hempcrete has a number of environmental benefits over concrete. It also has a number of general benefits too.

General Benefits

Here are some of the general benefits of hempcrete over concrete:

  • Stronger: Hempcrete is said to be 7 times stronger than concrete
  • Lighter: Hempcrete is about half the weight of concrete
  • Less cracking: Hempcrete is more elastic than concrete, which means it is less prone to cracking

Environmental Benefits

Using hempcrete instead of concrete can drastically reduce carbon emissions produced by our buildings.

In the UK for example, the construction and ongoing use of buildings accounts for over 50% of of carbon dioxide emissions. Studies have shown that, for each square meter of house walling, up to 200 kilograms of carbon dioxide is emitted from its construction. This works out to be around 40 tonnes of carbon dioxide emitted for a typical house.

Hempcrete, on the other hand, can actually remove carbon dioxide from the air, and trap it within the wall construction. The producers of Tradical Hemcrete claim that it has been found to lock up around 110 kilograms of carbon dioxide per m3.

So, which is it? “Hemcrete” or “hempcrete”?

Both! Hempcrete (with a “p”) is the generic name for the product. Hemcrete (without the “p”), is a proprietary version of hempcrete. Its full name is Tradical® Hemcrete®, and it’s a registered trademark of Lime Technology in the UK.
