Dark Light

Thanks to the growing demand to practice sustainability and reduce environmental pollution, eco-inventors have taken it upon themselves to come up with solutions that will help curb the threat of carbon emissions.

According to a recent study executed by the University of Sydney, international tourism accounts for approximately 8 percent of the world’s total carbon emissions. This was 3x higher than what was expected and is one of the many sobering statistics that have shed light on the different causes contributing to climate change.

With that in mind, let’s skip to the main section of the post and look at top innovations that are designed to make travel greener.

1. Water Seer

This is an invention that will allow anyone to have access to clean and safe drinking water without needing to use electricity, which in turn, makes it a more eco-friendly solution for all travelers. If you don’t know what a water seer is, it’s simply a device that can produce water from the air and has the ability to generate more than 10 gallons a day.

2. Solar Power

Solar power keeps getting cheaper and more easily accessible – a trend that has had a major implication on more than one billion people around the world who didn’t have access to electricity before.

Better yet, unlike regular or standard electricity, solar power isn’t generated using fossil fuels, which can produce harmful methane gases and carbon dioxide (the 2 gases that have been known to lower the quality of the air we breathe.)

Therefore, exploring renewable solutions like solar power to generate energy efficiently, quickly, and at a cheaper cost to millions of people should be a priority for all hotels and tourist attractions around the world.

3. Pyrolysis

Every year, millions of tons of plastic waste are accumulated around the world – and shockingly, only 16% of this waste gets to be recycled.

Things are about to change, however, thanks to advancements in pyrolysis. Pyrolysis is a promising circular model process that uses elevated temperatures in the absence of oxygen to chemically decompose organic materials.

With these innovations in its corner, the plastics industry will now be able to turn the tables and significantly reduce the number of plastics it throws in the different market sectors (while at the same time creating environmental, societal, and economic benefits.)

4. Public Electric Transport

Like most of us, I’m confident you use a car to move around during your adventures around the world – and regardless of whether it’s a private or public means of transport, chances are it leaves carbon footprints behind.

So, in their efforts to reduce every traveler’s carbon footprint, innovators have created electric cars. These inventions will reduce carbon emissions that contribute to climate change and smog, which will, in turn, improve public health and reduce ecological damage.

Countries providing ways for travelers to charge their electric vehicles on renewable energy (like wind or solar) will minimize these emissions even more.

China is a great example. The nation has over 250,000 electric buses driving through its cities every day, and adoption that has enticed European countries to follow suit. And while E-buses may seem pricier compared to traditional means of transport, they’re affordable in the long run, as one won’t need to spend a fortune importing oil.

5. LED Light Efficiency

LED lighting is quickly replacing traditional incandescent bulbs around the world simply because it’s more energy-efficient.

What’s more? These lights have the potential to profoundly transform the future of lighting in the world since residential LEDs (particularly Energy Star ranked products) use approximately 75 percent less energy and last 26 times longer compared to incandescent lighting.

With that in mind, if more travelers, hotels, and tourist attractions decide to transition to using LED lighting in their homes and businesses around the world, we will have moved a step closer to sustainability.

6. Reduce Food Wastage

Food waste is a huge problem, not only in our kitchens but also around the world. Did you know that around a third of all food produced for human consumption gets wasted each year – and that this not only results in financial losses but also takes its toll on the environment?

We can stop food waste (or at the very least try reducing it) by buying only what we need and no more while traveling around the world. Better yet, start buying organic food products instead of canned and use the FIFO (first in first out) rule to ensure nothing goes bad in your refrigerator before it’s used.

But in cases where you find yourself with more than you need, feel free to donate the surplus to the needy instead of throwing it away.


The great thing about sustainable tourism is the virtually unlimited number of innovations at our disposal. The few we’ve mentioned in this guide will allow each one of us to play a role in reducing carbon emissions to help the environment.
