As cities commit to bold climate targets and corporations sharpen their ESG mandates, one thing is becoming clear: sustainability demands better, smarter data. Aerial imagery has long helped us understand the environment, but traditional methods—like satellites and fixed-wing aircrafts—come with a heavy carbon cost.

Drones offer a cleaner, faster alternative that aligns with climate-conscious goals and the pace of modern planning. As we race towards a net-zero future, how we collect environmental data matters more than ever.

‍

What’s Fuelling the Push for Greener Data?

Across North America, both cities and corporations face mounting pressure to deliver on sustainability promises.

1. Cities Committing to Net-Zero Goals

Municipalities like Vancouver, Toronto, New York, and Calgary have pledged to hit net-zero emissions by 2040 or 2050. That means retrofitting buildings, expanding renewable energy, and preserving green space. Programs like Burlington’s 100% renewable energy push and Toronto’s Home Energy Loan Program show real investment in clean infrastructure.

But hitting these goals requires more than funding. Cities need reliable, timely data to track progress—and, it is here that aerial imagery plays a vital role.

‍

2. Corporations Are Held to Higher ESG Standards

Fortune 500 companies are being asked to report- and reduce- scope 3 emissions. ESG reporting has moved from a nice-to-have to a business imperative. At the same time, companies are grappling with rising operational costs, unstable geopolitical conditions, and shifting investor expectations. Balancing sustainability with financial resilience has become a matter of grave importance.

While cities and corporations are striving to meet these sustainability goals, the path forward is still obstructed by deeper, structural challenges.

‍

Why Progress Still Lags Behind Ambition?

The reasons aren't surprising—but they are persistent:

• Budgets are stretched thin, especially at the municipal level.
• Monitoring tools are often outdated or siloed.
• Policies don’t always align across departments or regions.
• Infrastructure wasn’t built with retrofitting in mind.
• And in too many cases, cities and organizations are flying blind due to incomplete or delayed data.

Without accessible, frequent, and trustworthy data, even the best climate strategies can stall before they gain momentum. That’s when the gaps become obvious: cities need more aerial data—data that’s not just accurate, but rich in detail, easy to access, and fast to deploy.

‍

Aerial Data Is Essential—But the Method Matters

High-resolution aerial imagery is critical for:

• Monitoring land use and vegetation health
• Mapping urban heat islands
• Verifying green infrastructure progress

and countless other things.

With better aerial data, cities can identify vulnerable urban heat zones faster, track green infrastructure rollouts in real time, and prioritize climate resilience investments with more precision.

Corporations, on the other hand, can use aerial insights to audit facilities for energy inefficiencies (Scope 1), verify renewable energy installations, and optimize real estate portfolios to reduce purchased electricity emissions (Scope 2).

But if the method of collecting that data is emissions-heavy, it undermines the very climate goals it's meant to advance. Traditional aerial methods—like satellites and fixed-wing aircrafts—provide coverage, but they also carry a significant environmental cost.

‍

The Carbon Cost of Traditional Aerial Imagery

As cities and companies work to reduce emissions, it’s worth asking: are the tools we're using aligned with the outcomes we’re aiming for? Satellites and fixed-wing aircrafts are widely used, but both come with substantial—and often under-discussed—carbon footprints. And while comparisons aren’t always straightforward, looking at the emissions across their full life cycles reveals a more complex picture.

‍

Fixed-Wing Aircrafts Are Carbon-Intensive—But Variable

Aircraft-based imagery missions burn a considerable amount of aviation fuel—and that directly drives emissions. Depending on the aircraft type and mission duration, the impact can vary significantly:

• Cessna 172 (single-engine): This is one of the most commonly used fixed-wing aircraft for general aviation purposes—and it’s often used in aerial imagery, flight training, and personal aviation. It is widely used due to its affordability, ease of operation, low maintenance costs & reliable performance in small-scale survey missions. However, A Cessana 172 emits 286 kg of CO₂ per mission.‍
• Cessna Caravan (Similar to Cessana 172) emits 2,965–4,151 kg CO₂ over 5–7 hours flight time. ‍
• Piper Navajo (twin-engine) & Beechcraft King Air 350 are also preferred due to their longer range, higher payload capacity (for camera equipment),  faster flight speeds & ability to fly at higher altitudes for broader coverage. Piper Navajo emits ~1,520 kg CO₂ over 5 hours & Beechcraft King Air 350 emits 4,208–6,313 kg CO₂ over 4–6 hours.

For perspective, a single Cessna 172 mission is roughly equivalent to burning 16–32 gallons of gasoline. A longer mission in a Piper Navajo, can generate emissions equivalent to driving a car over 9,000 miles.

Newer aircraft models and optimized flight plans can reduce fuel use, and in large-scale surveys, higher-efficiency jet aircrafts may offset emissions per square kilometer. But fuel consumption—especially for photogrammetry, where multiple overlapping passes are required—remains a core challenge.

‍

Satellites Carry Hidden Environmental Costs

It’s easy to assume satellites are a low-carbon alternative. In some cases—especially over massive regions or for continuous monitoring—they are. But their full life cycle tells a more complicated story:

• Launch emissions from rockets (e.g., Falcon 9) can exceed 28,000 tonnes of GHGs—equal to the annual footprint of more than 6,000 U.S. households.
• Satellite manufacturing is highly energy-intensive, requiring specialized materials and rigorous testing.
• Ground station operations use substantial electricity to power global networks for data reception & processing.
• End-of-life impacts include orbital debris and re-entry emissions, which may contribute metallic ash and greenhouse gases to the atmosphere.

While satellites excel at global-scale, long-term monitoring, their environmental impact is front-loaded and harder to mitigate. Advances in reusable launch vehicles and cleaner propellants are underway, but the challenge is far from solved.

‍

Responsiveness, Resolution, & Cost—Additional Trade-Offs

Beyond emissions, traditional aerial methods face several operational limitations:

• Limited flexibility: Aircraft and satellite missions are scheduled, not on-demand.
• Lower resolution: Many satellites still provide only RGB data with coarser resolution.
• Slow turnaround: From flight planning to image processing, it can take days or weeks to get usable data.
• High costs: Aircraft surveys require pilots, fuel, airspace logistics—and those costs scale fast. This puts frequent monitoring out of reach for many smaller municipalities or resource-constrained organizations.

Each method—satellite or aircraft—has its strengths, limitations, and ideal use cases. But when sustainability, responsiveness, and local resolution matter most, traditional platforms often fall short.

Drones: The Cleaner, Smarter Way Forward

Electric drones eliminate combustion, jet fuel, and launch emissions. As organizations look to reduce emissions, noise, and environmental disruption, drones provide a more compatible way forward.

‍

Near-Zero Emissions

Unlike fuel-burning satellites or aircrafts, most drones are electric and run on rechargeable batteries. This dramatically reduces operational emissions. For example, Spexi’s model cuts carbon output by up to 97% compared to a typical aerial flyover. Independent studies back this up—replacing traditional methods with drones for power line inspections, for instance, can eliminate hundreds of tons of CO₂ per year.

The core difference is simple: a helicopter can emit 230–250 kg of CO₂ per hour. A drone, by contrast, has near-zero emissions in flight—especially if powered by renewable energy. Even accounting for recharging and support logistics, the environmental impact is a fraction of traditional methods.

‍

Rapid, On-Demand Deployment

Drones require no runways or air traffic scheduling. They can launch in minutes, from rooftops, parks, or the back of a truck. This agility makes them ideal for:

• Post-storm damage assessments
• Green roof and canopy tracking
• Infrastructure checks in hard-to-reach areas

Because they’re lightweight and maneuverable, drones can operate frequently without disrupting traffic or requiring complex logistics—making it easier to get timely, relevant data when it matters most.

‍

Smaller Operational Footprint

Drones aren’t just low-carbon—they’re low-impact across the board. They produce far less noise than aircrafts (which can exceed 100–120 decibels) and don’t disturb wildlife or communities. In fact, many sustainable filming experts highlight drones as a preferred tool precisely because they’re quieter and more respectful of sensitive environments.

They also require less infrastructure—no hangars, no fuel trucks, and minimal personnel. That means less land disruption, fewer vehicle miles traveled, and a lighter overall footprint. A drone team can often operate with just a backpack, leaving the landscape largely untouched. This is especially valuable in natural areas, parks, or urban green spaces where preserving the ecosystem is key.

Taken together, the emissions savings, minimal noise, and lightweight footprint make drones a practical, future-ready option for aerial data collection.
