On November 22, 17 large chestnut trees that made up Gambetta Square were shot dead. In a redevelopment project, it was impossible to deplant and then replant them because of a very unbalanced root system. A decision that was not well received by Bordeaux in times of ecological crisis when a petition against this slaughter had gathered more than 10,000 signatures.
Between limited wealth and growing needs
Indeed, at a time when information flows from one end of the world to the other in a matter of seconds, it is impossible to ignore the environmental threats that weigh. Deforestation, melting glaciers, greenhouse gases, extinction of animal species… The power of social networks in particular gives us, sometimes unintentionally, access to testimonies and sometimes deplorable images of what is happening on our planet.
Many associations and ecological movements have emerged to try to combat these phenomena. Despite this, august 1st was announced as the day of overtaking : the day we consumed everything the planet can provide us in terms of natural resources in one year. This date came 2 months earlier than 20 years ago (September 1, 1998). According to WWF and statistics from the NGO Global Footprint Network, we would need 1.7 planets worldwide to support ourselves and 2.8 if everyone lived like the French.
In 7 months we have caught more fish, cut down more trees and harvested more than nature can provide us in a year. We have also emitted more carbon than the oceans and forests are able to absorb responsible for global warming.
According to government statistics, the average annual temperature has increased, we are talking about 1.6 degrees Celsius in Metropolitan France in 2017 compared to the reference years (1961 – 1990), the cause of all this echoes the high emissions of greenhouse gases. In summary, the significant presence of these in our atmosphere prevents the natural reflection of solar radiation into space but rather again causes a reflection towards the earth’s surface as a greenhouse effect thus warming our atmosphere. Fossil fuel combustion, industrial processes, tropical deforestation, agriculture, fertilizer use and the manufacture of electronic components including many anthropogenic causes of the increase in these gases. Reducing these emissions would lead to the adaptation of our technologies and lifestyles as well as the increase in biomass since it is the latter that naturally consumes gas such as CO2.

In 2010, on the right bank side, the Darwin eco-system project was born through the renovation of a 10,000m2 military heritage. The main areas of development were thus geared towards a refusal of air conditioning, the optimization of natural lighting and a major objective in terms of grey energy savings during the project’s construction.
Darwin has been powered by 100% green electricity since its inception and has been innovating since 2015 through the deployment of a 480 m2 photovoltaic roof in self-consumption to make its businesses autonomous in electric energy.
In 2017, the economic situation of the eco-system is defined by 3000 m2 of responsible shops, 6500 m2 of shared offices and 250 companies housed in coworking. At the same time, two-thirds of Darwinians use soft mobility solutions and it is estimated that a Darwinian worker emits 5 times less greenhouse gases than a worker on a conventional site. As far as recycling is concerned, 70% of waste is recycled in 20 different sectors and 90% of water needs are met through stormwater recovery.
There are still areas for improvement to be developed
Air quality and its pollution especially of greenhouse gases is greatly influenced by the circulation of transport, which is no longer a secret, are among the main sources of carbon dioxide (CO2). In terms of ecological issues, Bordeaux already has its tram, bus and bicycle lines available to combat the use of the car. However, by comparing the forecast travel times by bus or tram according to the TBM application with car journeys estimated by Waze, the car is still the fastest way. Therefore, still overall the most favoured means of travel within the metropolis although it is also the most polluting, the most expensive and the noisiest.
Even if the travel time will not necessarily help to change the opinion of Bordeaux regarding the use of their vehicle, it is important to note that cycling often comes in second position and even places itself in front of the car on some shorter routes (3 to 4 km). It is also easier to park your bike than your car, where the time to find a place can be very long and impact the real travel time.
Although this last point is still to be perfected, Bordeaux and its Darwin ecosystem are examples of ecological transitions proving that it is really possible to combine “Business” and ecology”
