Putting the world at scale

By the end of the 1980s, the world started to realize that it was facing a conjunction of global crisis, of an unprecedented magnitude and depth. These crises were ecological, social and economic, but also, in many countries, crisis of meaning.

World population

By 2050, the world population should reach 10 billion people according to the United Nations. This represents a 30% increase compared to 2019, and more than 10 times the world population at the dawn of the industrial revolution.

Co2 concentration

The CO2 concentration of the atosphere has been steadily increasing over the last 250 years, reaching 412 ppm in 2019, while it had remained between 170 ppm and 300 ppm for the last 800 000 years. CO2 is a major cause for climate change and ocean acidification.

Biodiversity loss

Accordind to IPBES, the current rate of global species extinction is hundreds times higher compared to average over the last 10 million years, and this rate is accelerating. The United Nations estimate that between 150 and 200 species become extinct every 24 hours.

Wealth inequalities

Because of high and rising inequality within countries, since 1980, the top 1% captured as much as 27% of total growth, twice as much growth as the bottom 50% individuals.

DIsplaced people

According to the United Nations, an unprecedented 70.8 million people around the world have been forced from home in 2018. Among them, 25.9 million are refugees, over half of whom are under 18 yo. Nearly one person is forcibly displaced every two seconds as a result of conflict or persecution.


According to the International Energy Agency, about 2.7 billion people still lack access to clean cooking, and household air pollution, mostly from cooking smoke, is linked to 2.6 million premature deaths. The IEA also notices that about 1 billion people are still lacking any access to electricity.

The United Nations played a key role in addressing these challenges by clearly identifying their origins and proposing a roadmap to solve them. In particular, the year 2015 was an important landmark for multilateralism and international policy shaping with the 2030 Agenda for Sustainable Development, which defined 17 Sustainable Development Goals (SDGs) for the world, and The Paris Agreement.

Achieving these goals will require a deep reorganization of our socio-economic models, driven by new infrastructure models, to integrate the notion of sustainability. From mobility to health care, education to security, we must design and implement innovative services adapted to the 21st century and beyond, and thus develop the sustainable infrastructures that will deliver these services.

The world needs a true change of method and scale, hence a tremendous mobilization and coordination of resources. The level of intensity needed is in fact comparable to a war effort. But without this confrontational logic, the coordination and mobilization of resources can only result from peaceful mechanisms, in particular of market mechanisms.

In this context, drawing from the work carried by Terrawatt Initiative since 2015 on the solar market, Scale aims at fostering the emergence of sustainable infrastructure services globally in pursuance of the United Nations’ Sustainable Development Goals.

Concretely, Scale participates in the structuring and development of infrastructure projects, to create innovative utility solutions, prove their technical, social and economical viability at an individual level, and create the conditions for their replication at broad scale.


The projects supported by Scale must offer a concrete and actionable solution to pursue at least one of the United Nations’ SGDs, without being detrimental to any of the others.
In particular, the projects must integrate the three main sustainability components: social, environmental and economic.


The projects supported by Scale must prove the viability of a given model and be easily replicable at broad scale.
This implies that the solution must be economically viable, competitive in the context of a tender process, without relying on any exceptional market conditions (humanitarian aid, etc.).
