Humanity is regularly confronted with major challenges and develops technologies, mechanisms, concepts and ideas to overcome them. The challenge we are currently facing is in everyone’s mind and mouths: climate change, which we are essentially the cause of through our activities and our consumption model.

Each decade sees the emergence of a great innovation: the internet in the 90s, the web 2.0 in the 2000s, the Uber and AirBnB model in the 2010s. Born with Bitcoin, digital currencies and registers are the disruptive technologies of the 2020s, and are the two tools which will enable us to significantly mitigate our contribution to climate change: this is my strong belief.

Tailored Contribution System (TCS) is a use case for digital currencies and ledgers set out in two phases:
TCS phase 1 is a multi-brand loyalty program rewarding participants for buying environmentally friendly products
TCS phase 2 is a consumer tax system in which tax rates are based exclusively on the carbon footprint of every single ingredient and component of consumer goods

Developed by Enée Bussac, trainer and expert in digital currencies and ledgers (see here), TCS phase 2 won the Wirecard Innovation Challenge 2019 (see here).
