Electric Buses in Chilean Mining: Measuring What Workers Actually Think
ESG Data Collection Transport MRV Carbon
Project Type: Clean Transport Transition | Electric Bus Fleet Replacement
Location: Atacama and Antofagasta Regions, Chile
Methodology: AMS-III.C
When a Bank Needs More Than Just Carbon Numbers
Mining workers in northern Chile spend hours each day travelling between remote villages and mine sites. For years, they rode diesel buses across desert roads—noisy, hot, and thick with exhaust fumes. When the fleet switched to electric buses across three major mining operations, the numbers looked good on paper: 49,465 tonnes of CO₂ avoided over ten years, 121 buses operating emission-free.
But the bank funding this transition wanted something most carbon projects don't bother collecting: what do the people using these buses every single day actually think?
That's not the kind of data you get from fuel consumption spreadsheets or emissions calculations. You need to ask the workers themselves. And in three remote mining communities spread across Chile's Atacama desert, that meant putting the survey directly in their hands.
The Questions That Actually Matter
The survey wasn't abstract. It asked specific, practical questions that reflected what matters on a multi-hour commute through the desert:
-
Does the air conditioning turn on when needed during the journey? Simple yes/no. Because when you're crossing the Atacama in 35°C heat, this isn't a luxury—it's whether you arrive at work already exhausted.
-
Are the USB charging ports on the buses functioning? Yes and working well / Yes but with problems / No / I don't use them. Workers need charged phones for safety, communication with families, and coordination during shift changes.
-
How satisfied are you with the electric buses compared to the diesel service? Five-point scale from very happy to very unhappy. The baseline question—does this actually feel like an improvement?
-
Have you noticed any improvement in air quality inside the buses and around them since their introduction? Four options ranging from significant improvement to worsening. This gets at whether the emissions reductions are something people can actually feel, not just measure.
-
How reliable do you think the service schedules are for getting to and from the mine? Five-point confidence scale. Electric buses are pointless if people don't trust them to actually show up.
-
Have you noticed any impact on your work productivity due to the new electric bus service—better rest, less fatigue, etc.? Five-point impact scale from significantly positive to significantly negative. This captures whether quieter, cleaner travel translates into tangible wellbeing benefits.
-
Have you noticed a reduction in noise during journeys on electric buses compared to diesel buses? Five options from great decrease to significant increase. Diesel engines are loud. Does electric actually make a difference people notice?
-
Do you feel the switch to electric buses contributes to less pollution in your community/area? Yes/No. Perception of environmental benefit matters—it affects whether workers see this as genuine climate action or just corporate greenwashing.
-
Do you think the switch to electric buses aligns with the company's environmental commitments? Open text field for workers to explain their thinking. This surfaced skepticism, support, or suggestions that multiple-choice questions would miss.
-
Do you feel more motivated or satisfied with your work knowing that cleaner technologies are being used for transport? Yes/No. Does climate action at work actually affect morale?
-
Do you have any recommendations or opportunities for improvement regarding the operation of electric buses? Open text. The most valuable question—specific, actionable feedback that only daily users can provide.
Every response was automatically tagged with GPS coordinates showing which route and village the feedback came from, timestamp, and anonymous demographic markers (which mine site, approximate shift pattern). Workers confirmed consent and understanding before starting, and all responses were genuinely anonymous—no names, no employee IDs, nothing that could identify who said what.
What the Geographic Data Revealed
The GPS tagging wasn't just for verification—it showed patterns the bus operators hadn't spotted. Complaints about air conditioning clustered on specific routes during afternoon shifts, when the sun hit the buses differently. One village reported charging port problems at three times the rate of others—turned out those were older bus models with a known electrical issue.
Satisfaction scores varied significantly between the three mine sites, even though the buses were identical. The difference wasn't the technology—it was how the transition had been communicated to workers. At the site where management had involved worker representatives in planning, satisfaction ran 30% higher. At the site where electric buses just appeared one day with no explanation, workers were more skeptical, even though the actual service was the same.
Route-specific feedback helped operators optimize schedules. Workers on one route consistently mentioned arriving late to shift changes—the electric buses were slightly slower on a particular uphill section, and the schedule hadn't accounted for it. A five-minute adjustment fixed the problem, but only because geotagged feedback showed exactly where the delay was happening.
How This Data Changed What Bus Operators Actually Did
The survey results didn't just sit in an ESG report. They drove operational changes within weeks.
Maintenance priorities shifted. Instead of servicing all buses on the same rotation, operators focused first on routes where workers reported the most problems. Charging ports were fixed on the older models. Air conditioning was recalibrated on buses running afternoon desert routes.
Training improved. Driver feedback (they filled out surveys too) combined with passenger data showed that some drivers weren't using regenerative braking properly, which affected the smoothness of the ride. Targeted retraining happened for those specific drivers on those specific routes.
Communication strategies changed. The mine site with lower satisfaction scores started regular worker briefings about the electric bus program—what was being monitored, what improvements were coming, why certain changes took time. Satisfaction scores climbed 22% over three months, with no change to the buses themselves. People just needed to know someone was listening.
Infrastructure gaps got filled. Workers mentioned feeling unsafe at certain bus stops after dark. The geotagged feedback showed exactly which stops needed better lighting. Two stops got solar-powered lights installed within a month.
Expansion plans got smarter. When the mining companies planned to add more electric buses, they used the satisfaction data to predict which routes would have the easiest transitions and which would need extra support. They also knew which features mattered most to workers—functional charging ports and reliable air conditioning topped the list, ahead of fancier interiors.
The ESG Reporting Nobody Could Argue With. ESG Data Collection Transport MRV Carbon
The bank had funded this transition partly for carbon credits, partly for ESG credentials. Most clean transport projects give funders a single metric: tonnes of CO₂ avoided. This one gave them a story backed by hundreds of worker responses.
Their ESG report could say: "89% of workers reported noticeable air quality improvement inside vehicles. 76% felt the transition aligned with company environmental commitments. Workers identified 23 specific operational improvements, of which 18 were implemented within the monitoring period."
That's the kind of data that holds up in front of investors, regulators, and skeptical journalists. It's not corporate spin about sustainability—it's verified feedback from the people actually affected, collected through a system that didn't allow cherry-picking results.

The demographic breakdown mattered too. Responses weren't clustered among younger workers or management—feedback came fairly evenly across age groups and job roles, which meant the improvements workers reported weren't just enthusiasm from people predisposed to like new technology.
Beyond the Carbon Credits
Chile's Atacama and Antofagasta regions had barely any electric buses before this project—0% and 1.4% of the fleet respectively. Shifting mining transport to electric was always going to be technically challenging. But technology only works if people actually use it.
By treating workers as partners in monitoring rather than just passengers, the project gathered data that strengthened every part of it. The carbon credits were verified and issued—49,465 tonnes of CO₂ avoided. The ESG reporting had substance that funders could actually use. The bank had evidence their investment created measurable social value. The bus operators improved their service based on specific, actionable feedback. And the workers saw that their input mattered—problems they reported got fixed, suggestions they made got implemented.
The geotagged survey responses created an evidence base that typical carbon projects simply don't have. When the next mining company considers switching to electric transport, they won't just see emissions calculations—they'll see proof that workers in similar conditions, doing similar jobs, actually preferred the change. And they'll see exactly which operational details make the difference between a successful transition and one that looks good on paper but fails in practice.
That's the piece most carbon projects miss. You can measure emissions reductions down to the tonne. But if you're not measuring whether people's lives actually improved, whether operators responded to feedback, whether the technology worked in real-world conditions—you're only seeing half the picture.
Why Education Changed the Quality of Data
The difference between educated and uneducated feedback is substantial. When workers understood that electric buses produce zero tailpipe emissions, their answers about air quality improvements weren't just subjective impressions—they were informed observations. They knew what to look for, what should be different, why it mattered.
When someone who'd learned about solar charging in the Atacama answered questions about whether the transition aligned with environmental commitments, they weren't guessing. They understood the energy source, the emissions reduction, the infrastructure required. Their skepticism or support came from knowledge, not assumptions.
This matters for ESG reporting. The bank couldn't just say "workers liked the buses." They could say "workers who completed education modules on electric vehicle technology and renewable energy reported measurable improvements in air quality, noise levels, and commute comfort, with 89% confirming the transition aligned with stated environmental goals."
That's the difference between opinion and informed feedback. The education module turned passengers into knowledgeable evaluators.
Your Project
Could Work Like This
If you're working on a climate or environmental project that needs verified community data, you're probably facing similar questions to the ones in this case study.
How do you prove your project is working beyond just the technical metrics? What data do your funders need for carbon credits or ESG reporting? How do you catch problems on the ground before they undermine your results? Most importantly—how do you ensure the people affected by your project actually understand and benefit from it?
The difference between projects that succeed and ones that struggle often comes down to whether you're measuring the right things. Carbon calculations tell you about emissions. Community feedback tells you whether the intervention is actually working in practice. Education ensures that feedback is informed, not just reactive.
