Can we use social networks to drive climate-positive BEHAVIOR?

San Francisco

Social networks can influence human choices on a massive, global scale. As a means for propagating changes in human behavior – both good and bad – social media has already demonstrated enormous power. So how do we harness that power for good?

What can each of us do to make efficient use of energy in the region?


Using energy efficiently: what exactly does it need for it? Which energy sources are available to us? How can we use these in the long term? Which centralized and decentralized solutions are available and where can their use be exhausted?

Can the CYBER-PHYSICAL realm of ICT connect humans, data, and devices to fight climate change?

San Francisco

Information and Communication Technologies (ICTs) connect humans to a vast, cyber-physical realm of sensors, devices and data. ICTs like AI and IoT can amplify and extend our ability to fight climate change, individually and collectively. But there are risks. How do we make it all work?

Can we create and curate quality CONTENT that inspires climate-positive action?

San Francisco

Social media content is designed to be compelling and engaging to users of social media, and can inspire users to take action. Can we create and curate content that maximizes engagement and action while being trustworthy and scientifically sound?

How can we bring positive change in citizen behavior to create energy efficient Dhaka city?


Dhaka city is facing the challenge of energy shortage everyday and one of the main reason behind energy shortage is energy consumption without necessity. This waste of energy by the citizens contributes a lot in the shortage of energy for this city.

Can we reduce the ecological FOOTPRINT of social networks?

San Francisco

Social networks have enormous potential as positive forces against climate change. But they are also massive consumers of resources and energy. Let's make storing and sharing data over social networks a net positive for the planet.

How do we make energy more sustainable?

Cities consume 78% of the world’s energy and produce 60% of its emissions. As urban population increases worldwide, cities are crucial to emission reduction efforts.


Cities have a key role to play in the energy transition which is central to address climate change and resource scarcity. Cities tend to build and implement local energy strategies, often ignoring the global issues, and fail to consider mid-term and long-term scenarii. However, many European cities are increasingly attempting to define their local energy strategies integrating both economic and environmental impacts. Copenhagen (Denmark) aims to become the first carbon neutral city by 2025 and Perpignan (France) produces all the electricity for its residents locally by 2015. In order to be effective in their energy transition, cities need to coordinate local stakeholders, provide detailed and relevant diagnosis of their region, and identify the potential for energy savings and renewable substitution. Mid and long-term strategies need to integrate the whole energy value chain, from production, distribution and consumption.

Fields that need to be improved to reach a future of sustainable energy in the cities:

  • The transport sector is responsible for approximately a quarter of total energy-related CO2 emissions.
  • The built environement is of the utmost importance to increase energy efficiency and the use of renewable energy sources.
  • Energy transition to a renewable energy system.
  • Energy efficiency has to be increased at all stages of the energy chain.
  • There is a growing need of new energy storage solutions and innovation
  • Low carbon energy transport system has to be developed, etc.
