The richest 10% emit between 36 and 45% of GHGs. Inhabitants of developed countries emit on average 13 tonnes of CO₂-equivalent/year compared with 1,7 for those in less developed countries.
Recent rapid technological developments are facilitating the energy transition:
The challenges are technological and physical but also societal and political challenges. A fundamental shift in our diet towardsless meat-based diets is a powerful lever.
They must be accompanied by other measures to avoid the rebound effect. When it comes to transport, for example, we need to avoid long journeys (particularly by plane) and opt as far as possible for public transport, or give priority to walking and cycling on a daily basis. Finally, improvingenergy efficiency is important, particularly for our buildings and industry.
One of the main tools is structural transformation of our society individual changes, however necessary, will only be sufficiently far-reaching if they are supported by global changes.
This would reduce our emissions by 40-70% by by 2050, notably through through sobriety(ensemble de policies, measures and daily practices that avoid demands on energy and resources, while ensuring the well-being of all within planetary boundaries).
You also need:
get out of fossil fuels, thanks to the electrification of uses coupled with the decarbonization of electricity
The deployment of CO₂ absorption to counterbalance residual emissions that are difficult to eliminate is inevitable if we are to achieve carbon neutrality( techno-logical, land management, acceptability, etc.)
Mitigating our GHG emissions emissions is also in synergy with numerous sustainable development objectivesthese include indoor and outdoor air quality, active modes of transport, diets, etc.
