Tech for Good: Navigating the Landscape of Social and Environmental Impact
This article was first published Ming Tan on the World Economic Forum Blog
“Tech for good” – a descriptor for the space where technology is deployed to take on big social and environmental problems – may be catchy but the phrase could mean many things.
The sector encompassing health tech, education tech, cleantech, femtech and enterprise environmental, social and governance (ESG) software is seeing increased investments, reaching $79 billion globally in 2021. But at the Tech for Good Institute (TFGI), we found that varying definitions across the tech for good ecosystem meant varying expectations. Without a shared understanding of tech for good, it’s no surprise that the jury’s still out on whether technology is delivering a net positive impact.
In February 2023, TFGI ran a flash poll on public perceptions of tech for good in Southeast Asia. Of the 212 respondents from Indonesia, Malaysia, the Philippines, Singapore, Thailand, and Vietnam, only 46% strongly agreed or agreed that technology and the digital economy have delivered their promise for the region. Almost as many (37%) stayed neutral.
Tech for good has proven nebulous as a concept, and perceptions across Southeast Asia indicate it has not delivered on its promise.
Like any industry, the digital economy can have positive and negative consequences on society and the environment. How then, should we assess the impact of technology and the digital economy?
Tech for good’s framework
At TFGI, we believe that digital technologies and the digital economy drive sustainable, equitable and inclusive development and economic growth.
Technology’s impact is derived from the technology itself and its business model, creating the use case for business and society. Historically, technology has been deployed for positive or negative outcomes – fission bombs falling over Hiroshima and Nagasaki in 1945 being a clear example of the latter. That said, under strict governance, nuclear technology has since been deployed across multiple commercial sectors, most notably in medicine.
Given tech for good’s expansive scope, we developed a simple visual representation of how different approaches may deliver on technology’s promise.
The vertical axis indicates if technology’s full social and environmental cost is considered (bottom half) and the degree to which non-economic benefit to society and the environment is realized (top half).
Nuclear technology’s example shows significant effort is needed to ensure safety in production, handling and disposal. The needs of the community, environment and future generations must be considered, as radioactive material can remain hazardous for many lifetimes. Only after the total costs and negative consequences are addressed may technology be considered to deliver a net-positive impact.
The horizontal axis highlights how the digital economy may add value to economic growth. The processing power of digital technologies’ ability to collect, store and manipulate data quickly, accurately and at scale may be deployed to prevent harm to society or the environment (left) or efficiently meet social or environmental objectives, such as increasing access, improving accuracy, reducing error or lowering cost (right).
Some digital technologies and their applications can also create whole new approaches to achieving non-financial positive impact, shown in the top layer. In the case of nuclear technology, its impact on medical imaging and diagnostics has transformed medicine.
Better tech for good
With this framework, we can better articulate how digital economy companies may realize tech for good.
1. Responsible tech seeks to do no harm
Responsible digital economy companies examine their systems, processes, products and services to identify and mitigate negative consequences in upstream development and downstream impacts of products and services.
Digital technologies can be inherently values-driven, so upstream considerations include developing systems with inclusion, security and data protection baked in, with transparency to build trust. For example, developers can proactively ensure datasets that train algorithms are unbiased or design systems for frictionless data sharing or systematic data protection.
Downstream considerations include maintaining consumer choice and protecting livelihoods and users’ health and well-being. With rapidly evolving digital technologies, operating responsibly is a moving goalpost. As regulators pay attention to players in the digital economy, the business case for mitigating negative impacts can be as straightforward as maintaining licences.
In our poll, only 14% of respondents thought responsibility alone constituted tech for good, suggesting sustainability is necessary but more is needed.
2. Supportive tech provides new ways of preventing harm
Several examples demonstrate the rise of supportive tech. For instance, automated safety systems in vehicles or manufacturing can reduce accidents or loss of life. Similarly, sensors and satellites that collect and analyze data have greatly enhanced weather monitoring, forecasting, and responses to severe weather events.
Another example is cybersecurity applications that use predictive artificial intelligence models to identify vulnerabilities and pre-empt cyber-attacks.
While technology could help or scale solutions, there must also be a change in goals, mindsets, practices and behaviours.”— Ming Tan, Founding Executive Director, Tech For Good Institute
3. Facilitative tech optimizes benefits by increasing efficiency
Technology that streamlines processes, saves time, improves convenience, increases access, reduces waste or lowers cost can be a value-add.
Examples include online to offline platforms, which match supply and demand for services and enable new livelihood and income opportunities while increasing consumer convenience. Other examples include data analytics to support decision-making, automation for repetitive tasks that reduce manual labour and minimize errors and communication technology to enable cross-border collaboration.
4. Transformative tech tackles global, national or local challenges
Transformative products, services and business models radically transform lives and livelihoods while solving the world’s most complex problems. In essence, transformative tech is disruptive, creating new or reinventing sectors.
Fintech’s impact on the financial industry is a case in point. Access to financing has long been difficult for micro, small and medium-sized enterprises (MSMEs) for physical inaccessibility and lack of formal documentation and collateral to access credit.
Today, digital financial services providers such as Grab Financial Group, SEA Money and Goto Financial can use alternative data, such as transaction data, to develop credit risk models for those with no collateral.
TFGI found that over 70% of digital lending users had previously been unable to secure financing from banks and other lenders. By reaching and serving customers digitally, these providers can offer micro-financing products and reduce customer costs.
Not mutually exclusive
That’s not to say that supportive, facilitative and transformative tech should not also be responsible. And transformative tech is often a subset of supportive or facilitative approaches.
As TFGI’s poll suggested, tech for good was most often associated with transformative impact. However, complex problems also have strong cultural and social dimensions when it comes to optimising efficiency and preventing harm. While technology could help or scale solutions, there must also be a change in goals, mindsets, practices and behaviours.
Therefore, if the expectation is transformative impact, it is unsurprising that tech for good appears not to have delivered on its potential. Yet, optimizing efficiency and preventing harm shouldn’t be discounted as having a positive social or environmental impact.
Tech for good may be a broad concept but it is not abstract. Whether enabling systems change or achieving precise outcomes, tech for good can solve problems, optimize benefits and help tackle the pressing social and environmental challenges of our time.

Net-zero target is within reach if pursued deliberately
By Marius van der Hama
As of 2022, air travel carbon emissions reached an estimated 800 Mt or 2% of the global energy-related greenhouse gas emissions. And while this was approximately 80% of the pre-pandemic levels, increasing demand for aviation services – projected to grow at between 2% and 5% by 2050 – will ultimately drive up the quantity of carbon emissions generated by the airline industry.
However, this adverse trajectory can be averted. By ramping up innovative aircraft technologies, “streamlining” flight operations and increasing the production and use of sustainable aviation fuels (SAFs), airlines can reduce the generation of carbon emissions by the quantities required to achieve Net Zero earlier than the 2050 target.
At Air France, we have taken the prerogative to accelerate our impact in this regard. For instance, we are continually upgrading our fleets to modern technologies, which generate much lower emissions. As of 2025, we will have added 38 Airbus A350s to our long-haul fleet and 60 Airbus A220s on our short and medium-haul fleet, replacing the A318 and A319 fleets. The new-generation aircraft produce 20% to 25% less carbon emissions, and their noise footprint has been reduced by a significant 40%. They also consume significantly lesser fuel. The aircraft on our fleet currently consume an average of 3.3 litres per passenger/100km. In comparison, the A350 consumes nearly 25% less at 2.5 litres per passenger/100km. This is as the A220 expends 2.6 litres per passenger/100km, thanks to the incorporation of close to 40% lighter materials (lithium aluminium and composite materials) in its construction.
Yet flight renewal is only part of our multi-pronged strategy to reduce the carbon footprint of our airline. We are also pioneering the transition to SAFs, which will be the main lever for decarbonising air transport in coming years. Produced from non-fossil fuel sources, the SAFs selected by Air France reduce carbon emissions by at least 75% over the entire life cycle, and can be used today without any modification to aircraft and flight operations. As part of the supportive ecosystem, we have engaged our customers to support the accelerated adoption of SAFs through a subscription option that allows them to voluntarily contribute during ticketing a fee to facilitate the use of sustainable aviation fuels (SAFs) in our flights, including cargo hauls. Customers are free to choose their level of investment, with a guarantee that their contribution will be exclusively used to purchase SAFs, cleaner alternatives to conventional jet fuel.
Meanwhile, we also run arrangements that favor low-carbon alternatives on shorter journeys, and more energy-efficient flights on longer journeys, helping our customers to minimise the overall carbon footprint of their trips. For example, in France, we have over the last 25 years offered a service that allows our customers to combine train and air travel in the same reservation, with guaranteed connections. This ‘intermodiality’ option is popular with customers travelling to and from Paris-Charles de Gaulle and the Paris-Orly airports, with more than 160,000 travellers using it every year.
Finally, from an operational standpoint, we are implementing eco-piloting techniques that significantly reduce aircraft fuel consumption. For instance, our pilots are trained to use single-engine taxiing, saving up to 700kg of fuel per departure and arrival for the Airbus A350. They also leverage AI-powered tools to optimize flight trajectories for fuel efficiency. Moreover, pilots can use bridge electricity instead of the aircraft’s auxiliary power unit (APU) before engine start-up, further reducing fuel usage.
All the aforementioned efforts align with Air France’s commitment to sustainability and environmental responsibility through prudent energy management and deliberate emissions reduction. By implementing innovative aircraft technologies, including the adoption of fuel-efficient aircraft, and investing in alternative fuels, as well as business practices that are considerate of our energy usage and waste production, Air France continues to set a benchmark for the aviation industry.

How Rwandans are Empowering Their Communities through Innovative Solutions
The Open Skies Fellowship in Rwanda effectively trained and chose 15 fellows through two cohorts. In March 2022, the initial cohort’s selection took place at our partner hub, IDA Technology, resulting in the selection of 10 fellows with promising projects. The workshop’s goal was to empower young local experts in cutting-edge technologies, providing them with the knowledge, resources, and skills necessary to transform their ideas from concept to prototype and eventually to market. Following the successful implementation of the first cohort’s projects, Open Skies organized another one-week workshop using the same process, leading to the selection of 5 fellows with outstanding projects for the second cohort. All these fellows were given mentorship and technology loans to support their project’s needs throughout the implementation.
IoT-BASED PROJECTS
In an era where technology continues to shape our daily lives, the Internet of Things (IoT) based devices have emerged as a powerful force in addressing and resolving societal challenges. These innovative devices created by our fellows interconnected through the vast network of the internet, have proven to be useful in finding effective solutions to some of our most pressing issues.
8 fellows worked on IoT-based projects where they came up with devices designed to solve challenges in their community.
Starting with Gasana Junior, He designed his E-Home project as a smart house to improve the quality of life for the aging population and individuals with disabilities. This encompassed features like automated lighting, ventilation, doors, and a crucial focus on security. The field that best captures his project is known as the “Internet of Things, or IoT, which describes devices with sensors, processing ability, software, and other technologies to connect and exchange data between devices and systems using the Internet.
Joselyne Nisingizwe designed the Murinzi Quick Box as an Internet of Things (IoT) device resembling a box filled with protective items such as pads and condoms, along with essential sexual, reproductive, and health information. It is deployed in small communities to provide accessibility to people with disabilities, allowing them to access these resources and report instances of violence conveniently.
Aimable Rubagumya developed a smart poultry farming solution, an innovative approach that harnesses advanced technologies to enhance poultry production. His creation is an Internet of Things (IoT) based system that enables farmers to monitor their coops by collecting data on temperature, humidity, carbon dioxide, ammonia, and dust. This system offers real-time notifications via Short Message Service (SMS) on both offline and online phones, as well as through email, to alert farmers when the hens’ conditions deteriorate, ultimately resulting in increased productivity.
Joyeuse Nishimwe’s idea was simple but involved complex skills using IoT devices. She designed smart beehive technology that allows a beekeeper to receive all the analyzed information related to their beads inside the hive at regular intervals and with the help of digital messaging systems (both via email and via phone).
For example, when the temperature decreases to the extent that bees cannot produce honey, a beekeeper will be notified and apply a normal heating method before bees start to leave. Data for each beehive is collected and presented in such a way that beekeepers can view the conditions of each hive, wherever they are, in real time.
Patrick Kubwimana created an IoT helmet for monitoring the health of people working in mines and underground tunnels. Smart helmets enhance miner safety by integrating sensors, including temperature, humidity, carbon monoxide, and heart rate, onto their helmets. These sensors, particularly the DHT11 which measures both temperature and humidity, provide early warnings for potential dangers such as explosions, flooding, and gas presence in mines.
Noella Abayisenga envisioned a device she calls Handtek, which is essentially a scanner built to check the sanitation status of one’s hands. The goal now is to help eradicate foodborne illness and maintain people’s hygiene through washing hands properly to avoid the spread of microbes. The device utilizes sensors, including a temperature sensor and light motion sensor, along with an ESP 8266 board that does a quick five-second scan and provides feedback. The system employs blue light along with an artificial intelligence system powered by TensorFlow and OpenCV, to analyze captured images.
Vicky Uwase created the Jambo Water Leakage Detection System (WLDS). This is a water leak and pipe burst detection system that will help people to monitor and notify water loss which leads to excessive expenses caused by leakage or frozen pipes. This system monitors the way water flows and if any leakage or pipe burst is detected it immediately sends a warning notification to a linked user’s smartphone or maintenance teams in charge. Jambo WLDS can also detect the temperature inside a pipe so it can notify the user or the technical team in case the temperature increases or drastically decreases within a pipe.
Kevine Giramata created a ‘’Safe baby app’’ whose system, based on IoT, employs sensors to monitor baby movements and activities, providing real-time information to parents. It assesses the baby’s well-being using humidity and temperature sensors. With machine learning, it can detect abnormal conditions and send timely notifications, either through SMS or a mobile app, addressing the challenge parents face with continuous child monitoring. The system is also trained to identify and alert parents to suspicious activities.
BUSINESS-RELATED PROJECT
Emmanuel embarked on a mission to build a cost-effective and widely accessible radio station that utilized his community’s available resources. By proposing innovative antenna construction methods, such as mounting on rooftops with materials like cement blocks, he aims to overcome geographical constraints and address frequency-related issues caused by increasing building structures. Beyond improved accessibility, the project seeks to inspire the younger generation, fostering critical thinking and intellectual growth. Building a radio station in his village was a commitment to community empowerment, youth inspiration, and contributing to societal well-being, marking a path for growth and development in Rwanda’s landscape.
VIRTUAL REALITY PROJECT
Babu Kamanzi as an advocate of virtual reality in education, Babu created a curriculum that can be integrated into VR sets with the purpose of enhancing the education system and classroom engagements of students in Rwanda. He gives the example of medical students, who instead of learning heart surgeries on real patients, can train on virtual patients with realistic simulations. Giving users the chance to practice and develop skills without real-world risks is one of the biggest advantages of VR solutions, and Babu hopes the adoption of VR and other emerging technologies in Rwandan high schools will help students learn in new and exciting ways.
CLIMATE CHANGE PROJECTS
Determined to make a difference, Zipora Shimwa decided to take matters into her own hands and embarked on a journey to revolutionize the way people cooked in her community. The result was a Smart Solar Thermal Cooking System (SSTCS) that would harness the power of the sun to provide a sustainable and efficient cooking solution. The SSTCS is an innovative cooking system with six key components: solar collectors, thermal energy storage, a smart control unit, an evacuated tube, a solar tracker, and a stove. Its high-efficiency solar collectors capture sunlight to ensure optimal performance, even on cloudy days. The thermal energy storage system enables uninterrupted cooking during low solar radiation periods, enhancing reliability.
Janviere Ingabire worked on a project called Home Cooking Gas Security, which aims to create an IoT device equipped to detect gas leaks, encompassing aspects such as gas type, sensor specifications, measurement range, alarm mechanisms, output control, response time, and operating temperatures (-10 to +55 Celsius). Crucially, the device not only identifies gas leakage but also takes preventive action by automatically blocking the gas supply before an accident can occur.
Denise Byukusenge Noticing the power challenges in certain regions of Rwanda, including her province, where access to large-scale hydroelectric power is limited and even simple tasks like getting a haircut require expensive transportation, Denise came up with solutions for those living far from electrical networks and facing economic hardships. She developed a project focused on generating energy from sustainable biogas, specifically derived from cow dung and toilet waste. With the goal of providing electricity access to individuals in her community.
A Geographic Information System (GIS) project
Evelyne Iradukunda her Campus Navigation System aims to empower students by providing a portable solution for seamless campus navigation. Utilizing ArcGIS, Evelyne converted the data into comprehensive maps, including class locations. This information was then transformed into shape files and integrated into code using Visual Studio Code with Leaflet. The Campus Navigation System aims to empower students by providing a portable solution for seamless campus navigation. Through a user-friendly digital interface with detailed maps, it addresses the challenges of being late to class and finding exam venues, showcasing the convergence of land surveying and technology to solve practical issues for students on campus.
Rwanda is referred to as the leading African country when it comes to technology, which is why it was easy for the project to be implemented in two cohorts in the country. Furthermore, Rwanda has been actively fostering a conducive environment for technology and innovation. There’s a growing ecosystem of tech startups, hubs, and initiatives, indicating a commitment to technological advancement. With this being said, the program has been successful as some fellows have been funded to further their projects and turned their business ideas into businesses, and others have acquired scholarships that will help develop their projects.
