How Carbon Capture Helps Achieve Net Zero Emissions

Editor: Arshita Tiwari on Aug 19,2025

Net-zero isn’t just a climate slogan, it’s a deadline. While clean power, electric everything, and behavioral tweaks get most of the airtime, carbon capture is the gritty tool that’s quietly expected to fill the gaps. So, what is carbon capture? In its simplest form, it’s the process of snagging carbon dioxide from smokestacks or straight out of the air and stopping it from joining the atmosphere’s heat-trapping party.

That carbon is either pumped deep underground or rerouted into products (we’ll get to carbon capture and utilization in a minute). But the bigger point is this: without carbon capture, hitting net-zero by 2050 isn’t just difficult, it’s mathematically impossible. The real question is, can it scale fast enough without becoming a distraction or fossil-fuel bandaid?

Carbon capture technologies — not one, but many

Let’s break down the main carbon capture technologies currently being deployed (or hyped):

Post-combustion systems

This is retrofitting 101. Factories or power plants bolt on equipment that scrubs CO? from flue gas using solvents like amines. It’s clunky and energy-hungry but widely understood — making it the flagship among early carbon capture technologies.

Oxy-fuel and pre-combustion routes

Here, fuels are burned in pure oxygen or converted to hydrogen and CO? first. These systems produce cleaner exhausts, making CO? easier to isolate. However, they often require redesigning entire facilities.

Direct Air Capture

This is the cool kid — pulling CO? directly out of ambient air. Technically futuristic. Financially brutal. Direct Air Capture is still expensive (think hundreds of dollars per ton), but climate models lean on it heavily for “negative emissions” as part of long-term carbon capture strategies.

Emerging experiments

From calcium looping to electrochemical capture — newer carbon capture technologies are climbing out of labs, promising lower costs and faster scalability. The truth? Most are still chasing commercial proof.

Carbon capture and utilization — turning pollution into product

Now to the moneymaking angle: carbon capture and utilization (CCU). Instead of burying captured CO? forever, CCU players use it to make new products — methanol, plastics, urea fertilizer, synthetic fuels, concrete, carbonated drinks, you name it. The appeal is obvious: you don’t just pay to hide CO?, you sell it.

Trouble is, the moment those products are burned or disposed of, that CO? usually makes its way back into the atmosphere. So while carbon capture and utilization sounds like a closed loop, it’s often just delayed release with better PR. That said, certain use cases — like mineralizing CO? into cement or injecting it into long-lived materials — offer real permanence. But industry needs to stop badge-slapping CCU as a blanket solution.

Is carbon capture good or bad? Let’s be honest

The internet wants a clean villain or hero story. Reality rarely plays along. So — is carbon capture good or bad? Depends entirely on how it’s used.

Where it’s good

Essential for hard-to-abate sectors: Think cement, steel, chemicals — industries that cough up emissions no matter how renewables grow.
Buys time while infrastructure shifts: Phasing out fossil plants isn’t overnight work. Carbon capture keeps emissions down during the transition.
Makes negative emissions possible: Paired with biomass or DAC, CCS can remove CO?, not just prevent future leaks.

Where it’s bad

Delays real transition: If companies use it to excuse fresh drilling and endless combustion, it’s nothing but a decoy.
Expensive as hell: Costs per ton of CO? are still high, especially for newer carbon capture technologies like DAC.
Risk of leaks or failure: Storage sites need decades (or centuries) of integrity. Any breach and that CO? bursts back into the sky.

So is carbon capture good or bad? — it lands somewhere in the messy middle. A powerful ally when deployed strategically. A dangerous crutch if treated as a cure-all.

The net-zero puzzle — why carbon capture still matters

Even with wind turbines spinning, solar panels sprawling, EVs humming, and diets greening — some emissions simply won’t budge. That’s why most serious net-zero roadmaps (IPCC, IEA, UN) build in carbon capture as a must-have, not a maybe. It acts like a vacuum cleaner: less sexy than solar, but often way more vital when tackling leftover CO? in stubborn sectors.

Critically, carbon capture and utilization can soften the economic blow by giving CO? a second life — something policymakers love. But to prevent greenwashing, two things need to happen:

Priority goes to hard-to-abate industries (not just oil majors syncing CCS with business-as-usual).
Capture must scale fast without draining renewables’ oxygen — i.e., no using CCS as an excuse to skip phase-outs or ignore efficiency gains.

Challenges nobody likes talking about

Infrastructure is missing: Thousands of miles of CO? pipelines and dozens of underground storage hubs are still needed.
Public pushback: People hear “pump gas underground” and think “earthquake or explosion.”
Regulation still lags: Without strict liability rules and real-time monitoring, trust remains low.
Costs are uneven: High-income countries can afford CCS deployment. Lower-income regions might struggle, widening the emissions gap.

All of this means carbon capture isn’t just an engineering feat — it’s a governance, finance, and public-trust game too.

Speeding up: how carbon capture can actually work

For carbon capture technologies to support net-zero in a real, not theoretical, way — deployment needs to explode (in scale, not literally).

Here’s what works:

Smart subsidies, not blind ones: Funding CCS in cement plants makes sense. Funding CCS to keep coal burning for 50 more years — not so much.
Robust carbon pricing: If emitting is expensive, capturing becomes comparatively cheaper.
Transparency on leakage and lifecycle CO?: One scandal could tank public support for a generation.
Link CCUS directly to phase-out plans: Capture shouldn’t prolong fossil operations. It should help shorten them, especially in hard-to-abate sectors where alternatives fall short.

Future-proof or fossil-fuel crutch? Final verdict

So, looping back — what is carbon capture? It’s a targeted technology meant to snag CO? before it causes more climate chaos. Done right, it’s essential. Done wrong, it’s a luxury shield for polluters.

The uncomfortable truth is this: getting to net-zero without carbon capture technologies is near-impossible within current industrial systems — but using them poorly could push us further away from decarbonization, not closer. That’s why the “is carbon capture good or bad?” debate is itself too binary. It’s as good (or as bad) as the policies and intent behind it.

Carbon capture and utilization, in particular, will need stronger scrutiny — if CO? used in fuels or plastics ends up back in the air, it’s circular marketing, not real climate progress. Yet if we start using CO? to manufacture long-lasting cement, stone, or infrastructure — it becomes a tool for permanence.

Conclusion: Hold the hype, use the hammer

In the end, carbon capture shouldn’t be viewed as a silver bullet — it’s more like a sledgehammer. Wrong hands, wrong aim — it’s destructive. Used surgically on the toughest industrial emissions and backed by honest targets, it can buy time and pull down numbers we know we can’t eliminate otherwise.

As net-zero moves from boardroom talk to bottom-line action, carbon capture technologies are about to face their biggest test: deliver real results — or be exposed as a shiny excuse. The climate can’t afford the latter.
