In-depth knowledge and protection of the climate based on rigorous measurements is already essential for human life and within this framework it is increasingly crucial for the world tourism industry.

This is the reason why the World Tourism Organization dedicates more and more time, patience and money to show that applies the so-called ecological, environmental sustainability, as a vital necessity.

The meaning of this certainty can be found in any scientific dictionary: it is not just about ensuring economic development, according to social aspects and environmental protection. It also means the future of humanity.

Explained a little more broadly, a normal situation is one that “can be sustained for a long time without depleting natural resources or causing serious damage to the environment.”

Clearly, measuring elements in the climate is a mechanism that can be used in extreme cases to eradicate or limit harmful processes that may threaten survival.

UNTWO has long since taken matters into its own hands and intelligence. At the recent ITB Berlin 2023, the most important travel fair in the world that just took place last week was a prioritized topic.

For example, one problem that (literally) looms over global tourism is the need to reduce greenhouse gases.

The issue is important for the sector because passenger traffic, generates a proportion of CO2 that requires vigilance.

As we all must know, carbon dioxide whose chemical formula is CO2 is a compound of carbon and oxygen that exists as a colorless gas under standard conditions of temperature and pressure (TPS).

It turns out that CO2 is closely related to the greenhouse effect, a process in which the thermal radiation emitted by the planetary surface is absorbed by atmospheric gases and radiated in all directions.

Intensive passenger traffic can leave a huge global CO2 footprint. That is why the World Tourism Organization is prioritizing the most modern measurement methods and equipment to avoid such a situation.

A crucial fact exposed at the ITB in Berlin is that the planetary tourism sector is responsible for 8% of global greenhouse gas emissions.

In Berlin, a free methodology and instrument was presented that allows hotels to calculate the CO2 footprint of a hotel residence in their facilities.

Measurement systems customized by multinational companies are already in the prioritized warehouse of science.

This means that many companies are developing their own solutions and there are many new tools that offer a simplified approach.

Tour operators are providing instruments of this profile that are well proven in their efficiency.

A still present problem of environmental sustainability is due to that is still no consensus regarding the inclusion of certain meters in international air transport.

That human way of moving through the air with fuels propelling them, as normal as the air we breathe, is a cause of such pollution.

When burning fossil fuels, such as coal, oil and gas, carbon dioxide (CO2) and other gases such as methane are emitted into the atmosphere.

The gases, far from being dissolved, are concentrated in the atmosphere and prevent the heat produced by the sun’s rays from escaping, causing what is known as the greenhouse effect with the most comprehensive and dangerous climatic consequences.

The most feared sequel in our times is climate change, which, according to scientists, is causing cataclysms that are on the rise.

Therefore, with the reader’s permission, this article could end as it began:
