12 June 2023 | Protect the environment

It’s the coming back of good days and of barbecues season! A great activity to gather with his friends, his family during the summer and share a friendly moment. Though barbecues pollute and have an important impact on the environment. 

Does coal barbecue emit a lot of CO2?

Coal barbecues are bad for the environment, between CO2 emissions and the necessary chemical products to power it. For example, for a barbecue with 4l of used coal, 2.2kg of CO2 are emitted, the equivalent of 20 km in a car. The coal barbecue isn’t advised so. 

Moreover, to make charcoal, it needs woods, so trees. Cut trees to cook his meat in the summer, is it responsible? 

We have observed that the pollution of coal barbecue isn’t only caused by used chemical products or by the smoke that it gives off but also with the type of coal used to make the meat grilled. The good compromise to fully enjoy your coal barbecue still by respecting the environment, is to choose the best coal with a better quality or certified. 

You can change and choose coal briquettes because they produce less dust than classic coal. They are faster and easy to light. It also exists coconut briquettes. They are manufactured with shells of coconut so no tree is cut for this process.  

Which alternatives to avoid the pollution of coal barbecue? 

To avoid the pollution of coal barbecues, we’re going to show you other types of barbecues more responsible of the environment and to feel less guilty during this summer. 

The advantages of the vertical barbecue:

Its position allows the grease of foods to fall into a dedicated bin and not into the embers. This method of cooking doesn’t produce any toxic smoke and allows you to eat healthier meat.

Furthermore, the vertical barbecue doesn’t need charcoal for its lighting. It works with all types of solid combustion, such as wood, vegetal waste or cardboard. 

Can we cook the meat with a solar barbecue? 

The solar barbecue is becoming more and more popular and is considered the most ecological. The only drawback to its use, it needs sun, so you can’t use it when you want, or late at night. 

It works with sunrays and thanks to this technique, you cook your grills without emitting CO2. 

The electric barbecue, is it ecologic? 

The electric barbecue is perfect for balconies and small gardens, working with the electricity. It doesn’t emit CO2 related to combustion. Even if its use is its own, the electric barbecue is in contrast very energy consuming. It consumes on average 2000w per hour. With an average emission of 50 g per kWh in France, an electric barbecue powered for an hour emits about 100g of CO2. It’s still 20 times less than the coal barbecue. 

And the gas barbecue, is it more ecological? 

Another alternative to limit his carbon impact still by keeping the good taste of the barbecue. The gas barbecue, heats with propane, a gas less polluting that emits less CO2 at the cooking, and emits 500 times less of tiny particles emitted. 


The pollution of coal barbecue is caused by many reasons and to protect the environment, it is preferable, to limit the carbon emissions, to opt for a vertical or electric barbecue. However, we need to take care of the brand of barbecue chosen, some vertical barbecues work with coal. And for the electric barbecue, we will need to be aware of their electric consumption to avoid taking a barbecue too much energy consuming. 

On our side, to contribute to the reduction of carbon emissions. Greenoco has developed a solution allowing to measure and reduce the carbon footprint of websites, by optimizing the necessary resources to the display of the sites. Thus, servers of data centers are less used and consume less energy, so rejecting less CO2.
