01 — Indoor Air Quality
What gas combustion produces indoors.
The combustion of natural gas or LPG inside a home releases a range of byproducts into the indoor air. The concentrations depend on the appliance type, the ventilation in the space and how long the appliance is running. What's consistent across the research is that gas combustion is not a clean process — and that most of the byproducts don't go where people assume.
Nitrogen dioxide (NO₂)
The combustion byproduct most studied
NO₂ forms when gas burns at high temperatures. It's the pollutant most extensively studied in relation to gas cooking and indoor air quality. Research consistently shows that gas cooktops raise indoor NO₂ concentrations above outdoor ambient levels, often significantly. The World Health Organization's guideline for indoor NO₂ is 25 micrograms per cubic metre as an annual mean — a figure measurable gas stoves regularly exceed during cooking in a typical kitchen. NO₂ is an airway irritant at elevated concentrations and is associated with respiratory symptoms at chronic low levels.
Benzene
A known carcinogen, present at measurable levels
Research published in Environmental Science and Technology (2023) found that gas stoves emit benzene — a compound classified as a known human carcinogen by the International Agency for Research on Cancer — at concentrations that can exceed those from second-hand tobacco smoke exposure in the same space. Benzene is present in natural gas itself, not only as a combustion product, which means some emission occurs even when burners are off but the supply valve is open. Concentrations are highest near the stove and dissipate more slowly in poorly ventilated kitchens.
Formaldehyde & carbon monoxide
Additional combustion byproducts
Gas combustion also produces formaldehyde (another IARC Group 1 carcinogen at higher exposures) and carbon monoxide (CO). CO is the more acutely dangerous of the two — incomplete combustion from a malfunctioning appliance can produce dangerous concentrations quickly, which is why CO detectors are required in gas equipped dwellings in most Australian states. Formaldehyde from gas stoves is a lower-level chronic exposure concern rather than an acute one, but it adds to the cumulative indoor pollutant picture.
Ventilation and concentration
Why modern homes amplify the risk
Older Australian homes with louvre windows, high ceilings and natural cross ventilation diluted gas combustion byproducts effectively — not by design, but by leakiness. Modern homes built to achieve strong NatHERS thermal performance ratings are significantly more airtight. That's good for energy efficiency and bad for indoor air quality when combustion appliances are operating. Without an externally vented rangehood running on high, pollutant concentrations from gas cooking in a modern sealed home can build to levels that remain elevated well after cooking ends.
The rangehood question. A rangehood that recirculates air back into the kitchen (common in apartments and older renovations) does not remove gas combustion byproducts — it filters particulates and then returns the same air. Only a rangehood ducted to outside the building actually removes NO₂, benzene and CO from the kitchen environment. When inspecting a property with gas cooking, check whether the rangehood is externally vented or recirculating.
02 — Health Risks
What the research says about gas and health.
The indoor air quality effects of gas appliances have been studied for decades, but the public health conversation in Australia has accelerated since 2022. The research base is not speculative — it includes peer-reviewed studies, systematic reviews and assessments by health agencies. The picture that emerges is nuanced but consistent: gas cooking contributes meaningfully to indoor pollutant concentrations, and chronic low level exposure to those pollutants carries health implications, particularly for children.
Childhood asthma
The strongest and most replicated finding
The link between gas cooking and childhood asthma is the most replicated finding in this research area. A 2023 meta-analysis published in the International Journal of Environmental Research and Public Health estimated that gas cooking accounts for approximately 12% of childhood asthma cases in Australia — comparable in population-level impact to passive tobacco smoke exposure. NO₂ is understood to inflame airways and reduce lung function in developing respiratory systems. The effect is strongest in homes where children spend significant time in or near the kitchen, and in homes with limited ventilation.
Adult respiratory effects
Lower risk, but not zero
The respiratory effects of gas cooking on adults are less pronounced than in children, partly because adult airways are developed and partly because adults typically spend less continuous time exposed during cooking. However, adults with pre-existing respiratory conditions — asthma, COPD, chronic bronchitis — are more sensitive to elevated NO₂ and CO concentrations. Research also suggests that cumulative lifetime exposure to indoor NO₂ at elevated concentrations may contribute to reduced lung function over time. The risk for healthy adults cooking occasionally in a well-ventilated kitchen is low. The risk for someone with asthma cooking daily in a poorly ventilated apartment kitchen is materially higher.
Benzene and cancer risk
A longer term, harder to quantify concern
Benzene is classified as a Group 1 carcinogen — meaning there is sufficient evidence that it causes cancer in humans, specifically leukaemia and related blood cancers. The cancer risk from benzene exposure through gas cooking is not the same as from industrial or occupational exposure at far higher concentrations. However, no safe threshold for benzene exposure has been established — health agencies use a precautionary approach. The practical implication for buyers is that benzene from gas appliances represents a chronic low level exposure with no established safe minimum, rather than a defined threshold below which risk disappears.
Highest risk groups
Who is most affected
Children under 12, people with asthma or chronic respiratory conditions, pregnant women and the elderly face the greatest health risk from gas combustion indoors. For buyers purchasing family homes — particularly those with young children — the indoor air quality implications of gas cooking are worth weighing explicitly. This doesn't make a gas property a dealbreaker in every case, but it's a consideration that didn't feature in most buyers' due diligence ten years ago, and it reasonably should now.
What good ventilation looks like. An externally vented rangehood running on high is the most effective mitigation in a gas kitchen. Opening windows while cooking is helpful but inconsistent. A CO detector is a safety baseline, not a health solution — it won't alarm at the chronic low level pollutant concentrations that represent the longer term health concern. The cleanest solution is induction cooking, which produces no combustion byproducts regardless of ventilation.
03 — Running Costs & Transition Risk
What gas dependence means financially.
The financial case for gas has shifted significantly over the past decade. A fully gas dependent home carries a fixed supply charge regardless of how much gas is used, exposure to gas price movements, and an increasing share of network maintenance costs as the customer base shrinks. Understanding the full cost of staying on gas — and the cost and timeline of transitioning off it — is part of assessing any property with gas appliances.
Fixed supply charges
Paying whether you use it or not
Natural gas connections in Queensland typically carry a daily supply charge regardless of consumption — often in the range of 50 to 80 cents per day, or roughly $180 to $290 per year before a single unit of gas is used. For a household that primarily uses gas for cooking, this supply charge can represent a significant portion of total gas spend relative to actual consumption. A comparable household on induction cooking with an electric or heat pump hot water system would have no supply charge at all. This fixed overhead is the baseline cost of staying connected to the gas network.
Gas price trajectory
A shrinking customer base pays more
As households electrify — driven by appliance replacement cycles, government incentives and rising awareness of running costs — the gas network loses customers. The infrastructure costs of that network don't reduce proportionally. The result is that the fixed and variable costs of gas supply are progressively distributed across fewer customers, placing structural upward pressure on gas prices over time. This dynamic is already visible in east coast gas markets. It's not a projection — it's an observable trend that affects the long term economics of any gas dependent property.
Appliance replacement cost
Electrification has an upfront cost
Transitioning a gas dependent home to all electric typically involves replacing three categories of appliance: the cooktop (induction), the hot water system (heat pump) and any gas space heating (reverse cycle). Each has an upfront cost. Induction cooktops range from around $1,000 to $4,000 installed. A heat pump hot water system is typically $2,500 to $4,500 installed, often partially offset by Queensland Government rebates. Reverse cycle replacement of gas space heating varies widely by system size. The full cost of electrification for a three-bedroom home might be $8,000 to $15,000 — meaningful upfront, but recoverable through lower running costs over a 5 to 10 year horizon for most households.
Resale implications
How buyers increasingly assess gas
The proportion of buyers actively preferring gas free properties is growing, particularly in the owner-occupier market for family homes. Gas is increasingly understood as a liability rather than a premium — a future cost to bear, rather than a feature to pay for. In a market that values sustainability credentials, a fully electrified home with solar and a battery may attract a different buyer profile and a stronger result than an equivalent home on gas. This is a trend, not yet a uniform market reality — but it's worth factoring into how you assess a gas dependent property's long term value.
Full cost comparison. To properly compare a gas dependent property against an electrified equivalent, include: the annual gas supply charge, annual gas consumption cost, likely gas price trajectory over your ownership period, and the eventual appliance replacement cost. Set against the electrification cost upfront plus lower ongoing energy costs. For many households the break-even point on full electrification is now well under 10 years, particularly with solar in place.
04 — Electrification Pathway
Switching from gas: the practical sequence.
Electrifying a gas dependent home is a staged process, not an overnight conversion. Understanding the sequence — and the relative priority of each switch — helps buyers assess what work a gas property requires and what timeline makes sense. Not every buyer needs to electrify immediately. But knowing what's involved, and in what order, turns a vague future cost into a specific plan.
Step 1 — Hot water
The highest-impact switch, often the first to make sense
Hot water is typically the largest gas expense in a Queensland home — particularly where space heating demand is low. Replacing a gas hot water system with a heat pump unit delivers the largest reduction in gas consumption and eliminates the biggest running cost. Queensland Government rebates of up to $1,000 are available for heat pump hot water systems (check current eligibility). A heat pump system paired with rooftop solar and set to run during solar generation hours can reduce hot water costs to near zero. When a gas hot water system is approaching end of life, this is the natural transition point — don't replace gas with gas.
Step 2 — Cooking
Induction delivers the indoor air quality benefit immediately
Replacing a gas cooktop with induction eliminates combustion byproducts from the kitchen entirely. Induction cooking is faster to boil, more responsive to temperature changes than most people expect, and significantly easier to clean. The main objection — that it requires induction-compatible cookware — is real but manageable; most quality cookware is already compatible, and a full set of induction-ready pots and pans adds modest cost. A standard 60cm induction cooktop with installation typically costs $1,200 to $2,500. Once the hot water switch is made, cooking is usually the next step — it also allows the gas supply to be disconnected if no other gas appliances remain.
Step 3 — Space heating
Reverse cycle is the established electric alternative
Gas space heating is less common in Queensland's subtropical climate than in Victoria or South Australia, but ducted gas systems exist in some Noosa properties — particularly in hinterland areas where winter nights can be genuinely cold. Reverse cycle air conditioning (heat pump) is the standard electric replacement. In Noosa's climate, a well sized reverse cycle system is highly efficient for both heating and cooling, with coefficients of performance of 3 to 5 — meaning each unit of electricity produces 3 to 5 units of heating. The cost of replacing a ducted gas heating system varies significantly depending on the existing infrastructure and room layout.
Switchboard capacity
Check before you plan
A complete electrification of a home — heat pump hot water, induction cooktop, reverse cycle heating and cooling, EV charging — places additional demand on the main switchboard. Older switchboards in pre 2000s homes may not have the capacity headroom for all these loads simultaneously without an upgrade. A switchboard upgrade adds $1,500 to $3,500 to the cost of electrification, but it's a once only improvement that enables all future electrification and EV charging without further work. When inspecting a gas dependent property, ask the electrician or inspector for their assessment of the switchboard's capacity to support electrification.
Disconnecting the gas supply. Once all gas appliances have been replaced with electric alternatives, you can apply to have the gas supply disconnected and the meter removed. This eliminates the daily supply charge entirely. In Queensland, the gas distributor is responsible for physically disconnecting and removing the meter — there's no cost to the customer for disconnection itself. Once disconnected, you also remove ongoing exposure to gas price movements and maintenance obligations on gas infrastructure.
05 — Solar & Battery
Why solar changes the electrification equation.
The financial case for electrifying a gas dependent home is straightforward. The case for electrifying a home that already has solar — or one where you intend to install solar — is significantly stronger. When you're not replacing gas with grid electricity but with electricity you're generating on your own roof, the running cost calculation changes fundamentally, and so does what energy independence actually looks like.
Solar alone
Shifting the source of your electricity
A household with solar that electrifies gas appliances is primarily running those appliances on solar-generated electricity — particularly for loads that can be scheduled to run during daylight hours. A heat pump hot water system set to run between 9am and 3pm draws from solar generation rather than the grid, reducing its effective running cost dramatically. Induction cooking at lunchtime is similarly offset. The more appliance loads you can shift to daytime hours, the greater the proportion of your consumption covered by solar, and the less exposure you have to retail electricity prices.
Solar plus battery
Near energy independence for most households
A home with solar and a battery that is also fully electrified is as close as most households get to genuine energy independence. The battery stores daytime solar generation for evening use, significantly reducing grid imports outside solar hours. For a typical Noosa household on a well sized solar and battery system with all electric appliances, annual grid electricity costs can fall to a few hundred dollars — sometimes less. This combination removes exposure to both gas price movements and most electricity price variability, and it positions the home well for any further grid cost increases over the ownership period.
What to look for in an existing system
Not all solar systems are equal
If you're buying a property with solar already installed, verify: the system size in kilowatts (kW), the panel brand and age, the inverter brand and age (inverters typically have a 10 to 15 year lifespan), whether there's a battery and its usable capacity in kilowatt hours (kWh), the current feed-in tariff arrangement, and whether the system is export limited or has a smart meter. A solar system over 10 years old may have degraded panels and an inverter approaching end of life — both factor into your assessment of what the system is actually worth and what it will cost to maintain or upgrade.
Installing fresh
Solar plus electrification as a combined upgrade
For buyers purchasing a gas dependent home without solar, combining solar installation with electrification is often the most cost-effective approach. The two projects complement each other — solar makes the electricity that powers the electric appliances far cheaper, and the combined upgrade can be financed as a single improvement. A 10kW solar system with a 10kWh battery and complete electrification in a Noosa property might cost $25,000 to $35,000 in total, but with near elimination of energy bills, payback periods of 7 to 12 years are realistic for many households. Queensland sunshine makes the economics particularly favourable.
06 — What to Check When Buying
Assessing a property with gas appliances.
Gas doesn't make a property a bad buy. But it does create a specific set of questions worth asking clearly and getting specific answers to before you commit. Here's what to look for and ask on any property with gas appliances — whether natural gas or LPG.
Is the rangehood externally vented or recirculating? A recirculating rangehood returns air — including combustion byproducts — back into the kitchen. Only a ducted-to-outside rangehood actually removes NO₂, benzene and CO from the cooking space. Ask, or check behind the rangehood housing if access is available.
Which appliances run on gas, and which are already electric? Some homes are partially electrified — electric cooktop but gas hot water, or gas cooking but electric heating. Understanding exactly which appliances use gas tells you what the supply charge is actually buying and which replacement costs are ahead of you.
What is the age and condition of the gas hot water system? Gas hot water systems typically last 10 to 15 years. An ageing system in a property you're buying is a near-term replacement cost. If it's within 5 years of end of life, plan to replace it — and use that opportunity to switch to a heat pump system rather than reinvesting in gas.
Is there a CO detector, and when was it last tested? Carbon monoxide detectors are a safety baseline in any gas equipped home. Check whether one is installed, whether it's within its expiry period (most have a 5 to 7 year lifespan) and when it was last tested. A missing or expired CO detector is a minor but meaningful red flag about how the property has been maintained.
What is the switchboard capacity, and can it support electrification? Ask your building inspector or an electrician to assess the switchboard. You want to know whether it can support a heat pump hot water system, induction cooktop and EV charger simultaneously without requiring a full upgrade. If an upgrade is needed, factor the cost into your assessment.
Can you see 12 months of gas and electricity bills? Actual bills give you the clearest picture of what this home costs to run. Look at the daily supply charge on the gas bill separately from the consumption charge — that tells you what you're paying just to stay connected. Compare total annual energy costs between properties to build a genuine lifecycle cost comparison.
Is the kitchen ventilation adequate for gas cooking as currently configured? Beyond the rangehood type, look at whether windows near the cooking zone are openable, and whether the kitchen layout creates a sealed space or one with natural air movement. A sealed galley kitchen with a recirculating rangehood and a gas cooktop is the highest-risk configuration for indoor air quality. It's fixable — but it's worth knowing what you're walking into.
For LPG properties: what is the tank size and what does delivery cost? LPG properties rely on bulk delivery rather than a mains connection. Ask about the tank capacity, delivery frequency, current pricing and minimum order requirements. Also check whether the tank is owned or rented — rented tanks can create switching friction if you want to change suppliers or electrify.
Gas is not a dealbreaker. Properties with gas appliances can be excellent buys — the considerations above are about understanding the full picture and pricing any transition work into your decision, not about avoiding gas properties categorically. A gas dependent home bought at the right price, with a clear electrification plan and solar already in place or planned, can be a very sensible purchase.
07 — Queensland Context
Where Queensland sits on the national picture.
Buyers often ask whether Queensland is moving to ban gas, and whether a gas property in Noosa faces regulatory risk. The honest answer is: not imminently, but the national policy direction is clear, and the economic pressures are real regardless of what any state government decides to legislate.
Queensland's current position
No ban in place as at May 2026
As of May 2026, Queensland has not introduced legislation banning new gas connections in residential construction. The Queensland Government has signalled support for gas as a transition fuel in the energy mix, and the LNP government elected in 2024 has not moved toward gas phase-out regulation. New gas connections remain available in urban areas served by the gas network. For existing properties, nothing in current Queensland law requires removal or phasing out of gas appliances.
What other states have done
The national direction is toward electrification
Victoria announced a ban on new gas connections in new homes from January 2024 — the first state to do so. The ACT introduced a similar ban effective from 2023. The Northern Territory, South Australia and Western Australia have not introduced bans, though South Australia and WA have both signalled moves toward electrification in planning and building frameworks. The National Construction Code 2022 does not mandate electrification but has tightened the energy performance requirements that make gas systems relatively less attractive in new builds.
Australia's Future Gas Strategy
The federal policy frame
The Australian Government's 2024 Future Gas Strategy sets a path to net zero emissions by 2050, with natural gas playing a "targeted, transitional and declining" role over time. The strategy does not mandate residential phase-out at a national level, but it establishes the clear policy intent: gas in residential use is an interim fuel, not a permanent one. Government incentives for electrification — heat pump rebates, energy efficiency programs, home battery incentives — are aligned with this direction and reflect where the policy and subsidy framework is heading.
The practical implication for buyers
No immediate regulatory risk, but real economic risk
The risk for Noosa buyers from gas is not primarily regulatory — you won't be forced to remove gas appliances in Queensland any time soon. The risk is economic: rising supply charges, a shrinking customer base spreading network costs, and an eventual appliance replacement cycle that favours electric alternatives. A gas dependent property bought today will need to transition at some point. The question is whether you plan that transition or inherit it at the next appliance failure — and at what price.
08 — LPG Properties
Gas in the hinterland: LPG specific considerations.
In parts of the Noosa hinterland — and in some areas of coastal Noosa that are not served by natural gas mains — LPG is used as the gas supply. LPG carries all of the indoor air quality and health considerations of natural gas, plus a set of additional cost and logistics factors that are specific to the bulk delivery model.
Indoor air quality
Same combustion byproducts as natural gas
LPG combustion produces the same pollutants as natural gas combustion — NO₂, CO, formaldehyde and benzene. The indoor air quality considerations described earlier in this guide apply equally to LPG properties. The different fuel source does not change the chemistry of what burning gas in a kitchen produces. If anything, LPG appliances are sometimes older and maintained less frequently than urban gas appliances, which can increase incomplete combustion and CO emissions.
Cost structure
Price volatility and delivery logistics
LPG is priced per litre or per kilogram and delivered in bulk. Prices vary by supplier, contract terms and the distance of the property from the distribution depot. Unlike natural gas (which has a regulated supply charge), LPG pricing is more volatile — it tracks international LPG markets and can move significantly between delivery cycles. Rural and hinterland properties can face premium delivery charges. The combination of price volatility, delivery logistics and the absence of any supply security means the financial case for electrifying LPG properties is often stronger than for natural gas-connected properties, on pure running cost grounds alone.
Tank ownership
Owned vs rented — it matters
LPG tanks on properties may be owned by the property owner or rented from the gas supplier. A rented tank is contractually tied to the supplier — you can't simply switch suppliers without returning the tank and arranging a new one. This creates friction if prices increase and you want to change suppliers, or if you decide to electrify and want to remove the tank. When inspecting an LPG property, establish whether the tank is owned or rented, and if rented, what the contract terms are. An owned tank gives you flexibility; a rented tank with a long term contract is a constraint worth understanding before purchase.
The case for electrifying LPG properties
Often the strongest financial argument
For hinterland properties on LPG, the financial case for full electrification is typically the most compelling of all the gas property scenarios. High LPG per unit costs, delivery volatility and the lack of any supply charge offset from a regulated network mean that replacing LPG appliances with an induction cooktop and heat pump hot water system usually delivers strong payback periods. With hinterland solar resource often excellent and properties tending to have good roof area, a solar-plus-battery-plus-full-electrification upgrade makes particular sense. It also removes all ongoing dependence on deliveries — which matters in areas accessible only by single roads that can be affected by floods or fire events.
09 — Research Findings
What the global research actually shows.
The research on gas cooking and health has grown substantially since 2020. The findings below come from peer-reviewed studies, government health agencies and academic institutions. Where the science is contested or where methodological debate exists, that's noted — the goal here is an accurate picture, not a one-sided one.
Australia — Medical Journal of Australia, 2018
12.3% of childhood asthma attributable to gas stoves
A study published in the Medical Journal of Australia calculated the population attributable fraction (PAF) of childhood asthma linked to gas cooktop use in Australia. The finding: 12.3% of current childhood asthma cases — around 2,756 disability-adjusted life years (DALYs) annually — were estimated to be attributable to gas stove exposure. The study noted that 38.2% of Australian homes used gas as their primary cooking fuel at the time. The authors included researchers from the University of Sydney and Sydney Local Health District. The study also found that fitting all gas stoves with high efficiency externally vented rangehoods could significantly reduce this burden.
United States — International Journal of Environmental Research and Public Health, 2023
12.7% of US childhood asthma cases linked to gas cooking
A 2023 study published in the International Journal of Environmental Research and Public Health estimated that 12.7% of current childhood asthma cases in the US are attributable to gas stove use. State-level figures varied significantly — in Illinois the estimate reached 21.1%, in California 20.1% and in New York 18.8%, reflecting the higher prevalence of gas cooking in those states. The study drew on a meta-analysis of epidemiological research spanning North American and European cohorts. It's worth noting that the methodology has been challenged by other researchers, who argue the effect size estimates may overstate the causal relationship. The debate is ongoing in the peer-reviewed literature.
United States — Environmental Science & Technology, 2023
Gas stoves emit benzene above secondhand smoke levels
A Stanford University and PSE Healthy Energy study published in Environmental Science and Technology tested 53 gas stoves across California and measured benzene emissions across all phases of stove use — burners on, burners off and during ignition. The finding that drew the most attention: a single gas burner on high could raise indoor benzene concentrations above levels associated with secondhand tobacco smoke exposure in the same space. The study also confirmed that benzene is emitted even when burners are off, because it is present in natural gas itself. Benzene is classified by the IARC as a Group 1 carcinogen with no established safe threshold.
United States — Science Advances, 2024
NO₂ from gas stoves persists for hours after cooking ends
A 2024 study from the same Stanford and PSE Healthy Energy research group, published in Science Advances, measured NO₂ concentrations across US homes with gas stoves and found that unsafe levels of nitrogen dioxide persist in indoor air for hours after burners are switched off. The study estimated the annual societal cost of NO₂ exposure from gas and propane stoves in the US at approximately USD $1 billion. The research highlighted that the health burden is not distributed evenly — lower income households and those in older, more densely occupied housing face disproportionately higher exposures.
International — World Health Organization
Indoor NO₂ guidelines regularly exceeded during gas cooking
The WHO's indoor air quality guideline for NO₂ is 25 micrograms per cubic metre as an annual mean. Research consistently shows that gas cooking in a typical kitchen — particularly without external ventilation — raises NO₂ concentrations well above this threshold during and after cooking. Studies have measured hourly average NO₂ concentrations in kitchens exceeding 200 micrograms per cubic metre during active gas cooking, which is eight times the WHO annual guideline. The WHO classifies NO₂ as a respiratory irritant with particular effects on developing airways in children.
United States — Columbia University / Bronx intervention study
Switching to induction cuts indoor NO₂ and CO measurably
A Columbia University study monitored 20 low-income households in the Bronx before and after replacing gas stoves with induction cooktops. Homes were monitored continuously over multiple seven-day periods measuring NO₂, CO and PM2.5. The study found that switching to induction produced measurable reductions in indoor NO₂ and CO concentrations. This is one of the few intervention studies — as opposed to observational studies — that directly measured the air quality improvement from replacing gas with electric cooking in real households. The findings supported the theoretical case for induction as an effective indoor air quality intervention.
A note on the science. The research linking gas cooking to childhood asthma and elevated indoor pollutants is robust and replicated across multiple countries and research groups. However, some of the specific population-level estimates — particularly the PAF figures for childhood asthma — have been contested on methodological grounds. The direction of the evidence is consistent: gas cooking raises indoor pollutant concentrations, and those concentrations have measurable health effects. The precise magnitude of the population-level burden is an area of ongoing scientific debate.
Gas is a known quantity. What matters is whether you've priced it properly.
A gas dependent property isn't a bad buy — it's a buy with specific known costs, a clear transition pathway and a timeline that's yours to decide. The mistake is treating gas as a neutral feature rather than a variable with real financial and health implications over the ownership period.
