The Fossil Fuel Elephant: Why Green Tech Needs Real Targets

The fossil fuel elephant green tech can’t ignore

Negotiators just wrapped up another round of UN climate talks in Belém, Brazil. Temperatures were brutal, flooding hit the venue, and a literal fire disrupted sessions. Yet the final agreement still avoided two words that matter more than any press release: “fossil fuels.”

For anyone working in green technology, that’s the uncomfortable disconnect. We’re building solar farms, smart grids, AI-driven efficiency tools—while global climate diplomacy still struggles to say plainly what needs to shrink: coal, oil, and gas.

This matters because green technology doesn’t live in a vacuum. Policy, finance, and public trust decide whether your solution stays a pilot forever or scales fast enough to change emissions curves. The latest climate talks are a reminder: if we don’t align tech, policy, and markets around phasing down fossil fuels, we’ll keep optimizing around the edges instead of hitting the core.

In this post, I’ll break down what this “fossil fuel elephant” means for climate tech, how AI is already reshaping greener systems, and where the real business opportunities sit as governments, companies, and citizens push beyond watered‑down agreements.

1. What climate talks aren’t saying—but green tech has to

The blunt reality: there’s no credible climate pathway that keeps expanding fossil fuels while hoping efficiency and offsets bail us out. Yet that’s effectively the stance when major agreements skip the phrase “fossil fuels” altogether.

For founders, operators, and sustainability leaders, that gap isn’t just political drama—it’s a planning constraint.

Where the tension really lies

Most countries now have net-zero targets on paper. At the same time:

• New LNG terminals are planned or under construction.
• Subsidies and tax breaks for oil and gas persist in many regions.
• Short-term energy security arguments still default to fossil expansion.

So you get this strange two-track reality:

• Track 1: Public commitments to net zero, green growth, energy transition.
• Track 2: Infrastructure that bakes in 20–40 more years of fossil dependence.

Green technology companies have to decide which future they’re building for. If you assume the world actually follows through on its climate promises, fossil-heavy assets become stranded, and low-carbon infrastructure wins. If you assume status quo politics, you under-invest in transformative solutions and over-invest in incrementalism.

I’m firmly in the first camp: bet on the physics, not the politics. Physics doesn’t negotiate. Every additional ton of CO₂ hangs around for centuries. Once that finally collides with public pressure, regulation tends to move fast—just ask coal.

What this means for your roadmap

If you work in climate or green tech, treat the climate talks as a lagging indicator. The real signals to watch are:

• Utility procurement plans: Are they buying renewables + storage or new gas peakers?
• Corporate PPAs and climate disclosures: Are your customers locking in long-term renewable contracts?
• Finance flows: Are banks and funds tightening rules on fossil-heavy projects and rewarding low-carbon ones?

Your product strategy should assume that fossil exposure increasingly becomes a liability—for your customers and for you. That pushes the opportunity squarely toward:

• Grid flexibility and storage
• Electrification (buildings, vehicles, industry)
• Demand-side management and efficiency
• Low-carbon materials and processes

Green technology that directly substitutes or shrinks fossil use will compound in value as regulations catch up.

2. AI as the quiet engine of green technology

While diplomats argue over wording, AI is already doing something more useful: squeezing carbon out of real systems today. You see it in energy, cities, industry, and even agriculture.

Here’s the thing about AI and sustainability: the most effective applications aren’t the flashy ones. They’re the unglamorous optimizers that run 24/7 and quietly reduce waste, emissions, and costs.

From pigeons to power grids

The newsletter that sparked this article ended with a surprising note: B.F. Skinner’s pigeon experiments helped inspire reinforcement learning, the branch of AI that learns by trial and error.

That same idea—reward the behavior you want, penalize what you don’t—now powers some of the most impactful green tech systems:

• Grid optimization: AI agents learn when to dispatch batteries, curtail loads, or absorb surplus solar.
• Building controls: Algorithms continuously tweak heating, cooling, and lighting to maintain comfort with less energy.
• Industrial processes: Control systems learn to minimize fuel use and material waste while meeting quality targets.

In other words, the pigeons pecking for food tokens weren’t just a quirky psychology experiment. They laid conceptual groundwork for the AI tools that now help keep lights on without firing up an extra gas turbine.

Concrete examples that are working now

You don’t need speculative science fiction to see AI-driven green tech in action. Here’s what’s already live in 2025:

• Smart grids: Utilities are deploying AI to forecast demand, predict renewable output, and balance loads. That allows higher penetration of variable wind and solar without compromising reliability.
• Fleet and route optimization: Logistics and mobility platforms use AI to cut fuel use by optimizing routes, loads, and charging schedules for EVs.
• Predictive maintenance: AI spots anomalies in turbines, transformers, and industrial assets before they fail, extending lifetimes and reducing resource use.
• Process control in heavy industry: Cement, steel, and chemicals are using AI-based control to reduce energy intensity per unit of output.

The pattern is simple: wherever you have repeated decisions that affect energy use or emissions, AI can usually improve them.

If your product sits anywhere in the energy, mobility, built environment, or industrial stack, an AI layer that optimizes for both cost and carbon isn’t a nice-to-have—it’s a competitive necessity.

3. Health, data, and sustainability: why they’re more connected than they look

The newsletter also highlighted progress in noninvasive testing for endometriosis—a condition that affects over 11% of reproductive-age women, often taking close to a decade to diagnose.

On the surface, that’s a healthcare story, not a climate one. But the underlying trend matters for green technology too: we’re moving from reactive, high-impact interventions to early, data-driven, low-impact ones.

The lesson from better diagnostics

Traditional endometriosis diagnosis often requires surgery to collect tissue samples. That’s invasive, expensive, resource-intensive, and slow. New noninvasive tests aim to:

• Use biomarkers and imaging instead of surgery
• Detect disease earlier
• Reduce cost and complexity for patients and providers

That’s basically the healthcare version of what sustainability needs:

• Detect energy waste and equipment problems early (with sensors + AI)
• Avoid “surgical” interventions like full system rebuilds where efficient retrofits or tuning would work
• Reduce resource use across the lifecycle, not just at the point of failure

Green tech can learn a lot from this:

The most sustainable system is the one you don’t have to rip out and replace because you were blind to its early warning signs.

Data is the common denominator

Whether you’re:

• Training AI to interpret medical images,
• Teaching models to forecast power demand,
• Or scoring buildings on their real energy performance,

you’re tapping the same underlying shift: high-resolution, real-time data driving better decisions.

For sustainability teams, this means:

• Stop thinking of “data” as an IT problem.
• Treat it as core climate infrastructure.
• Invest in clean, connected datasets across energy use, assets, and supply chains.

If you don’t, you end up like the traditional healthcare system: overusing invasive, late-stage interventions because the earlier, smarter options weren’t in place.

4. AI risk, public trust, and why sustainability teams should care

The newsletter also touched on darker AI headlines: a tragic case involving a teenager and an AI chatbot, concerns about AI companionship, and questions about AI displacing jobs. On the surface, these look like a different policy fight—but they land squarely in the lap of anyone building AI-heavy green tech.

Here’s the uncomfortable truth: if people don’t trust AI, they won’t trust your AI-powered sustainability solution either.

Why trust is a sustainability issue

Think about where many green technologies need AI:

• Automated demand response systems controlling loads
• Smart thermostats and building controls adjusting comfort levels
• EV charging managed by algorithms
• Industrial control systems tuned by models

If users, regulators, or employees believe AI is opaque, unsafe, or unaccountable, you’ll face:

• Slower procurement cycles
• Heavy-handed regulations that limit innovation
• Resistance from operators who bypass or disable your systems

The risk isn’t theoretical; we’re watching governments debate age limits for social media, restrictions on AI companionship, and responsibilities of AI companies in high-stakes contexts. Sustainability won’t be exempt.

How to build AI-powered green tech people accept

If you’re shipping AI in a climate context, you should be able to clearly answer:

1. What decisions does the AI make? Be specific. Dispatching batteries? Adjusting temperature setpoints? Recommending maintenance windows?
2. What are the failure modes? If the model is wrong, what’s the worst realistic outcome—discomfort, higher bills, equipment stress, safety issues?
3. What guardrails exist? Human overrides, hard limits, fallback modes, and clear incident processes.
4. What’s explainable? Can an operator understand why the system did something without a PhD in machine learning?

If those answers aren’t simple and defensible, your technology will struggle in real-world deployments, especially as AI regulation tightens.

The opportunity here is to differentiate: “green + safe + transparent” is a far stronger selling point than “AI-powered” alone.

5. Turning policy frustration into green-tech opportunity

So we’re back to where we started: another round of climate talks ends with vague language, while the atmosphere keeps accumulating CO₂.

The easy reaction is cynicism. I’d argue the smarter reaction is focus.

For people building or buying green technology, the path forward looks like this:

1. Build for a fossil-constrained future—even if the text doesn’t say it

Assume that:

• Carbon will get more expensive over the coming decade.
• Fossil-heavy assets will face earlier retirement than their planned lifetimes.
• Disclosure rules will tighten and expose greenwashing.

Then prioritize solutions that:

• Replace direct fossil use (electrification, alternative fuels).
• Reduce demand altogether (efficiency, circularity, reuse).
• Make variable renewables more valuable (flexibility, storage, forecasting).

2. Treat AI as infrastructure, not a buzzword

The companies that win in green technology will:

• Bake AI into core operations (forecasting, control, optimization), not tack it on as a marketing bullet.
• Combine domain expertise (energy, industry, buildings) with responsible AI practice.
• Quantify impact in both emissions reduced and cost saved, down to concrete percentages.

If you can say, “Our platform cut building energy use by 23% across 180 sites in 12 months,” you’re in a different league than “we use AI to optimize sustainability.”

3. Design for early warning, not heroic rescue

Borrowing the lesson from noninvasive medical tests:

• Invest in monitoring, metering, and anomaly detection.
• Flag inefficiencies while they’re cheap to fix.
• Help customers avoid expensive, carbon-intensive retrofits by acting earlier.

The greenest kilowatt-hour or ton of steel is the one you never had to produce because you found and fixed waste sooner.

4. Make trust a core feature

If your product uses AI, your trust story is part of your climate story:

• Be explicit about safety limits and human control.
• Provide simple dashboards that show what the system is doing and why.
• Give users agency: opt-out controls, manual modes, transparent data policies.

You’re not just selling efficiency; you’re asking people to let software steer critical infrastructure. Treat that as the privilege it is.

The gap between climate headlines and lived reality can feel huge, especially after another UN summit that tiptoes around fossil fuels. But the most meaningful progress right now isn’t in the communiqués—it’s in the systems thousands of engineers, operators, and founders are quietly upgrading.

If you’re building or buying green technology, you don’t need to wait for perfect language in a global agreement. You need to pick a side in the real transition: one where fossil fuels shrink, data and AI make everything smarter, and trust becomes a core design constraint.

That’s where the physics are pointing. The only real question is how quickly your organization decides to act like it.
