Will AI replace environmental engineers?
A little.
This job scores 70 out of 100 on Still needs a humanOur headline score for each job, from 0 to 100. Higher is safer: AI can do less of the work, or does it less well.It combines how much of the job AI can do with how well AI does it compared with a qualified person, and it is always shown beside those answers.How the score works · More in the glossary (higher is safer). Today people do 65% of the work with AI’s help, and 35% still needs a person.
AI does it: AI can do the task largely by itself. AI helps: a person still does it, faster with AI. Needs a human: AI can do little of it yet.
No two jobs leave the same print
Every job gets its own fingerprint, drawn from its code. The amber ridges are the share of task time that still needs a person. Below them, the same ridges are written out in ones and zeros: slate for the work AI helps with, white for the work AI can do.

When AI could largely do this job: 2037–2051

How this job could shift, year by year
We run this job as ten scenarios spread across its replacement range. In each, the score moves towards the bottom band (Largely: AI could largely do the job) by the year that scenario reaches it, slowly at first and faster later, as adoption usually goes. Each bar splits the ten by the band they put the job in. The model stops at 2060. How the timeline works

What’s stopping AI taking over?
The things that keep this work with people, strongest first. Each is scored 0 to 100 from O*NETThe US government’s free database of about 1,000 jobs, listing each job’s tasks and how much each one matters.Run for the US Department of Labor.

What would it cost to hand the work to AI?
The share of the year AI could handle (632 of 2,080 hours a year), priced two ways. Both are ranges, not quotes.
Robots and humanoids
AI software can only take the work at a screen. The rest needs a robot that can do it.

Which AI skills does this job lean on?
The job’s task time split by what an AI model would need to be good at, and where models stand today.
Still needs a human: 70/100↑ safer
The amber matter on the outside holds its orbit: that is the task time that still needs a person. The slate matter circling the inner disc is the work AI helps with. The white matter is the share AI can do; it spirals in and is gone over the edge.
People are asking
How often people ask whether AI will replace this job: on Google, and by estimate, in AI assistants.

The AI figure is DataForSEO’s estimate from Google’s “People also ask” data, not a count from any AI assistant. UK workers are ONS employment figures matched to this job, so the UK rate per 1,000 is an estimate. Search figures are not part of our open dataset.
What the AIs say
We asked four AI assistants the same question: will AI replace this job in the next 10 years? One word (Yes, Partly or No), then one sentence. Our own answer, from the data: Still needs a human: 70/100 ↑ safer. Will AI replace them? A little.
AI will automate some modeling, monitoring, and reporting tasks, but environmental engineers will still be needed for judgment, fieldwork, regulation, design accountability, and stakeholder decisions.
