Green Software Engineering: Building with the Planet in Mind

When Sulaimon Adejumo talks about software engineering, he doesn’t just talk in terms of scale, uptime, or performance. He talks in kilowatts. In emissions. In how much energy your API call just consumed, and how to make sure the next one consumes less.

Sulaiman Adejumo

A Senior Software Engineer with deep roots in infrastructure and systems design, Sulaimon is part of a new breed of engineers rethinking how software affects the environment. Not just in theory, but in measurable, actionable terms. His work centers around one goal: designing software that is as kind to the planet as it is to users.

Sulaimon is a practitioner of Green Software Engineering, a field at the intersection of sustainability and computer science. While many teams optimize for speed or scalability, Sulaimon adds another critical metric: energy efficiency. “Every line of code has a carbon footprint,” he often reminds teams. “The question is: are we optimizing for that?”

But Sulaimon doesn’t preach. He proves. In project after project, he has developed systems that monitor energy consumption across software components from frontend load times to backend computation. He’s helped teams visualize where carbon usage spikes, and where it can be trimmed. His approach is methodical: track, analyze, and optimize.

One of his greatest challenges, and contributions, has been in quantifying what was once invisible. With cloud-based systems and microservices sprawled across providers and regions, the environmental impact of even a small product decision can be significant and easy to overlook. “We used to measure performance in milliseconds. Now, we also measure it in millijoules,” Sulaimon says with a smile.

To that end, he’s led the development of internal tooling that tracks compute intensity and storage use across deployments. He introduces engineering teams to carbon-aware development strategies like scheduling workloads for times of low grid impact, or caching to reduce unnecessary compute. Not because it’s trendy, but because it’s necessary. But what sets Sulaimon apart maybe isn’t so much technical competence, it’s his ability to drive change without angst. His co-workers describe him as a bridge-builder: he engages product managers, designers, and engineers in the sustainability conversation without shame or technical jargon. “He doesn’t shame people into caring,” one collaborator says. “He makes you want to.”

Sulaimon is also open with the trade-offs. The most environmentally friendly solution isn’t always the lowest-cost or the fastest. But he believes engineering excellence is about making thoughtful, well-informed choices. “It’s not about writing perfect code,” he says. “It’s about writing conscious code.”

For teams building new systems, retrofitting old ones, Sulaimon has become a go-to partner in designing for both impact and efficiency. His work is shaping not just how products perform, but how they behave in the ecosystem they’re deployed in.

He’s not waving a green flag in the air. He’s coding one into the system.

MTN Group has begun rolling out MTN One TV, a new entertainment proposition designed to make digital video content more accessible, relevant, and flexible for customers across African markets.

MTN Launches One TV with Free-to-View, Pay-as-You-Go

Introduced in line with MTN’s Ambition 2030 strategy, MTN One TV brings together local storytelling, live channels, international programming, and market-specific viewing options tailored to how customers across the continent access and pay for digital entertainment.

The proposition is designed to give customers greater choice in how they watch content, with viewing models that may vary by market and can include free-to-view content, advertising-funded experiences, pay-as-you-watch access, and subscription offerings.

Depending on local availability, customers may also be able to pay through airtime, Mobile Money, and other locally supported payment methods, helping to reduce common barriers to streaming access.

Beyond enhancing customer experiences, MTN One TV creates new opportunities for African creators, broadcasters, advertisers, and ecosystem partners by helping connect content to wider audiences through MTN’s scale across connectivity, payments, and digital services.

By bringing together a broad mix of content experiences under a single proposition, MTN aims to support greater content discovery, broader audience reach, and sustainable growth across Africa’s digital entertainment ecosystem.

Anchored in MTN’s strategic platforms of Connectivity, Fintech, and Digital Infrastructure, MTN One TV forms part of the Group’s broader ambition to build digital experiences that create value for customers while enabling participation and growth across Africa’s digital economy.

“Entertainment is increasingly becoming an important gateway to digital participation,” said Selorm Adadevoh, MTN group chief commercial, strategy and transformation officer.

“Through MTN One TV, we are leveraging the scale of our connectivity, fintech, and digital capabilities to make relevant content more accessible while creating new opportunities for Africa’s creative and digital economies. This is aligned with our ambition to deliver digital solutions for Africa’s progress.”

MTN One TV is being introduced progressively across MTN markets through a phased rollout approach that reflects local market needs, existing services, and partnership opportunities.

Over time, MTN will bring together a combination of video capabilities, content partnerships, and customer experiences under the MTN One TV brand to create a more consistent and scalable entertainment proposition across its footprint.

Through MTN One TV, MTN continues to extend its role beyond connectivity by combining entertainment, payments, and digital services to deliver experiences tailored to the needs of African consumers.

The rollout supports MTN’s Ambition 2030 vision of leading digital solutions for Africa’s progress while expanding access to digital entertainment across the continent.

IATA Drops Bombshell: Nigeria Among World’s Most Expensive Countries to Run an Airline

International Air Transport Association (IATA) has identified Nigeria as one of the most expensive countries in the world for airline operations, citing high taxes, charges and operational costs that continue to weigh heavily on local carriers.

IATA Drops Bombshell: Nigeria Among World's Most Expensive Countries to Run an Airline

IATA’s Regional Vice President for Africa and the Middle East, Kamil Al-Awadhi, disclosed this during the association’s Annual General Meeting held in Rio de Janeiro.

Al-Awadhi said that although Nigeria’s Minister of Aviation and Aerospace Development, Festus Keyamo, had been pursuing reforms aimed at improving the aviation sector, airlines operating in the country still faced enormous cost pressures.

According to him, the high-cost operating environment has continued to affect the profitability and competitiveness of Nigerian airlines, making it difficult for the industry to realise its full potential.

He noted that excessive taxes, regulatory charges and other operating expenses remained major obstacles to airline growth across the region, with Nigeria ranking among the most challenging markets from a cost perspective.

Al-Awadhi urged member states of the Economic Community of West African States to adopt a proposed 25 per cent reduction in aviation taxes and charges to ease the burden on airlines and passengers.

According to him, lowering taxes and charges would reduce airfares, stimulate passenger traffic and strengthen the competitiveness of carriers operating within West Africa.

He stressed that a more supportive policy environment was critical to unlocking the economic benefits of aviation, including increased trade, tourism and regional integration.

Industry stakeholders have consistently advocated lower taxes and regulatory fees, arguing that the current cost structure makes air travel less affordable and limits the growth of the sector.

IATA’s latest remarks add to calls for governments in West Africa to implement policies that will promote a more sustainable and competitive aviation industry across the region.
