Getting it right: Building AI infrastructure that works for Australia

Zero Emission Byron — Fri, 16 Oct 2026 01:39:11 +0000

Our stand: Our submission to the Federal Government says data centres should bring their own clean energy, and households shouldn’t pay for theirs.

Australia is about to build a lot of data centres to run AI. The national energy market operator expects their electricity use to rise roughly seven-fold by 2035–36, from about 3% of grid demand to 13%.

That much new demand has to come from somewhere. If it isn’t matched by new renewables and storage, it pulls from existing supply. That pushes up wholesale prices for everyone and keeps ageing coal and gas plants running longer. One analysis puts NSW wholesale prices up to 26% higher by 2035 in that scenario.

On 7 October, Zero Emissions Byron | Northern Rivers made a submission to the Department of the Prime Minister and Cabinet’s consultation, Getting it right: Building AI infrastructure that works for Australia. Our position is simple. Data centres can help the energy transition, but only if the rules are enforceable, not voluntary.

What we asked for

Bring your own clean power. Large data centres should fully offset their demand with new renewable generation and firming, built before or alongside the load, not after.
No diesel backup. On-site generation and backup should be renewable only. Contracts for power should be for renewable electricity only.
Don’t pass the bill on. Operators should pay the full cost of network connections and upgrades, so those costs don’t land on households and local businesses.
Water first, then cooling. Use recycled and non-potable water first and drinking water last, with efficiency standards that tighten over time. Water use is set to roughly triple within five years.
One national rule. If each state sets its own rules, operators shop around for the weakest ones.
First Nations as partners. Traditional Owners should be involved from the earliest feasibility stage, before sites are shortlisted, with free, prior and informed consent.

Why it matters here

Regional areas like ours are in the frame for future sites because they have land, sun and wind. That can be an opportunity: new demand that underwrites new local renewables. But only if communities are part of the decision and aren’t left carrying the costs.

5 Questions to ask before believing a Net-Zero pledge

Zero Emission Byron — Wed, 09 Sep 2026 02:53:22 +0000

Net zero has become the go to phrase in corporate climate talk. Almost every big company has one now: a promise to hit net zero emissions by some future date, usually 2050. Sounds great. Ticks a box. Makes for a nice headline. But here’s the thing: a pledge is only as good as what sits behind it. Plenty of net-zero commitments turn out to be long on ambition and short on substance. So how do you tell a credible plan from a well-branded press release?

Here are 5 questions worth asking.

1. Does it include a real interim target, or just a distant deadline?

“Net-zero by 2050” is an easy thing to announce and a hard thing to be held accountable for, because nobody currently working at the company will still be there to answer for it.

The credibility test is whether the pledge includes near-term, checkable milestones: targets for 2027, 2030, 2035, with public reporting against them each year. A plan that only names an end date, with nothing in between, is a plan nobody can actually verify until it’s too late to matter and too late for anyone to be held accountable.

2. Does it cover Scope 3 emissions, or just the company’s own operations?

Emissions are split into three buckets:

Scope 1 is what a company burns or releases directly.
Scope 2 is the emissions baked into the power it buys.
Scope 3 is everything else: suppliers, transport, and the big one, what happens when customers actually use the product.

For a mining company or an oil company, Scope 3 is where almost all the real damage lies. So, when a pledge only talks about Scope 1 and 2, it’s bragging about the small stuff while the big stuff stays out of frame.

Pledges that quietly limit themselves to Scope 1 and 2 can look impressive while ignoring the bulk of a company’s real climate footprint.

Case in point: BHP. Its 2024 Climate Transition Action Plan, unchanged in its FY2025 filing, promises to cut operational Scope 1 and 2 emissions by at least 30% by 2030 and reach net zero operations by 2050. Nice. But then, BHP admits it’s “not currently in a position to commit” to any hard Scope 3 target. That’s a big gap, because BHP’s own numbers show Scope 3 runs to roughly 40 times its Scope 1 and 2 emissions combined. You can’t claim net zero while you’re still growing your fossil fuel business.

3. Is the company still expanding the thing it claims to be phasing down?

Case in point: BP’s 2050 net zero pledge functions as a form of rhetorical cover. It’s a secure public commitment because it’s distant enough to require no immediate action. In actual fact, the near-term targets (production, capex allocation) move in the opposite direction.

What’s actually happening to the “hard” numbers? 2020: pledge to cut oil and gas output 40% by 2030. 2023: watered down to 25% by 2030. 2025: production target dropped from the reset entirely, oil and gas capex raised to ~$10bn/year (~20% increase), renewables capex cut ~70%. That’s not a wobble. It’s a colossal retreat over five years. It ends in an outright reversal on the measures that were supposed to work on decarbonising, like output volume.

4. Who verifies the numbers. Are they published in full?

Self-reported progress isn’t the same as verified progress. Credible pledges are backed by independent, third-party auditing and disclosed with enough detail that outside researchers, journalists, and watchdog groups can actually check the numbers.

Also worth watching: whether a company stays inside the accountability frameworks it originally signed up to, or quietly exits them.

Case in point: between December 2024 and mid-2025, nearly every major North American and several global banks withdrew from the UN-convened Net-Zero Banking Alliance. This was the framework used to set and report on their climate targets since 2021. Leaving the shared framework means there’s no longer a common standard or outside body checking their numbers against everyone else’s.

When the referee leaves the field, the score becomes whatever each team says it is.

5. What happens to emissions when the company outsources or offsets them?

Two moves are common when direct emission reductions get hard. First, outsourcing energy-intensive work to third-party suppliers who don’t have to report it back, and second, buying carbon offsets instead of cutting emissions at the source.

Neither is inherently dishonest, but both can be used to make a footprint look smaller than it is.

The bigger picture

With no real enforcement power over corporate net-zero claims, accountability so far has come mostly from investors, journalists, NGOs, and independent trackers rather than regulation.

The binding part of any commitment language is the cost of leaving it. Once that leaving-cost drops, like activist investor pressure, or a lax regulatory environment, the pledges turn out to be exactly as they always were. Voluntary.

That’s not a reason for cynicism about every pledge!

It’s simply a reason to read past the headline number and ask 5 questions before deciding whether a company’s climate promise is a legitimate plan or a well-designed piece of marketing.

Mullumbimby Civic Centre Battery Announcement

Zero Emission Byron — Wed, 15 Jul 2026 08:00:41 +0000

A community-led push for resilient, renewable power takes a major step forward Zero Emissions Byron (ZEB) is excited to share an update on a project we’ve been championing since early 2025: bringing solar and battery storage to Council-owned community facilities across the Shire.

How it started

In early 2025, ZEB Chair Anne Stuart and Jill Moonie of the Brunswick Residents Association (now a ZEB Board member) lobbied Byron Shire Council to embrace renewable energy on its community buildings and invest in battery storage. Their case was simple: given the Shire’s recent history of bushfires, floods and extended power outages, community resilience matters — and batteries paired with solar could help deliver it. By September 2025, Council had agreed to investigate whether solar and batteries could be installed on community facilities to provide power in an emergency. A Community Battery Working Group formed soon after, spending five months exploring possible operating models. The idea was twofold: a replicable model that puts batteries on Council-owned facilities with existing or potential solar — feeding energy back to the grid at night for a financial return — while also providing backup power when the grid goes down.

With the Working Group’s support, Council engaged renewable energy consultants Beam Consulting to assess which facilities could best support battery storage, what the community benefits would be, and what it would cost.

First site: Mullumbimby Civic Centre

The first system proposed is a 10kW solar PV + 24kWh battery energy storage system (BESS) for Mullumbimby Civic Centre. Beam Consulting’s assessment involved:

Desktop analysis — checking network supply capacity and connection limits, gathering electricity interval data, and reviewing energy tariffs.
Site inspection — assessing the switchboard’s location, condition and spare capacity, checking available space and compliance for battery and rooftop solar, and identifying locations for solar panels, the battery, converters, load-shedding control circuits and cable routes.
Design output — preliminary system layouts and design drawings.

Three ways to run it

The consultants modelled three operating scenarios for the site:

Load Following + Backup (0% reserved) — maximises grid offset and financial savings, but leaves no guaranteed battery reserve for outages.
Backup Power Resilience (100% reserved) — maximises outage protection, but forgoes day-to-day financial and emissions benefits.
Optimised (50% reserved) — a blend of both, balancing daily savings with guaranteed backup capacity.

Putting it to the test

To understand how the system would perform in a real emergency, outage simulations were run under two conditions:

Typical sunshine: an average simulated outage delivered roughly 53 hours of backup power.
Storm conditions (7% solar irradiance): an average simulated outage delivered roughly 22 hours, with the shortest simulated outage providing around 4 hours using only 20% load shedding — an area the assessment flagged as improvable with more aggressive load shedding.

These figures assume 80% of the site’s load is essential, managed through clear manual load-shedding procedures for staff during an outage.

Why Mullumbimby Civic Centre

The site is a well-established community hub for disaster response, already has air-conditioning (valuable for heat resilience), and has some consumption data available through its existing solar monitoring — making it a strong candidate to lead the way.

Funding update

An Expression of Interest was submitted under the NSW Community Building Partnership 2026 grant program specifically for Mullumbimby Civic Hall. The project was shortlisted, and a detailed application went to the NSW Community Building Partnership on 17 July 2026. This
state grant program supports local infrastructure projects that strengthen the wellbeing of NSW communities.

The funding outcome will be announced on 22 January 2027.

Free Power and Cheap Upgrades: A Big Energy Double

Zero Emission Byron — Wed, 08 Jul 2026 05:05:55 +0000

Households now have access to two new programs that lower power bills and, just as importantly, help cut the emissions that come from the way we generate and use electricity. Both programs work by shifting how and when we use energy, and by making it cheaper to swap old, inefficient equipment for clean, efficient alternatives. Here is what they are, how they help reduce emissions, and how to get started.

Free electricity in the middle of the day

From 1 July 2026, eligible households can access free electricity every day between 11am and 2pm through the Solar Sharer Offer. You don’t need rooftop solar to take part, and renters are eligible too. Households can use up to 24 kilowatt hours of free power during the three-hour window.

This matters for emissions because the middle of the day is when rooftop and grid scale solar output is at its highest across New South Wales. At these times, there is often more solar power available than the grid can use, so some of it goes to waste or is exported at very low or even negative prices.

By encouraging households to shift energy hungry tasks, such as running the washing machine, dishwasher, air conditioner, pool pump, water heater or EV charger, into this window, the offer helps make full use of clean solar generation that would otherwise be curtailed. Less reliance on fossil fuel generation during the evening peak, when coal and gas plants typically ramp up to meet demand, means fewer emissions overall.

To join, contact your electricity retailer to opt in. You will also need a smart meter, which your retailer can arrange to install if you do not already have one. Because electricity costs a little more outside the free period, the real savings, and the real emissions benefit, come from shifting as much use as possible into the free window rather than simply using power as usual.

Cheaper upgrades through the Home Energy Saver program

The second initiative tackles emissions from a different angle: helping households replace old, energy hungry equipment with efficient, all electric alternatives. From 17 June 2026, the NSW Government's Home Energy Saver program offers zero interest loans of up to $15,000, repayable over as long as ten years, to eligible households with a combined taxable income of up to $210,000.

The loans can help cover the cost of rooftop solar, home batteries, insulation, reverse cycle air conditioning, switchboard upgrades, ceiling fans and draught proofing. Later in 2026, eligible concession card holders and households earning up to $80,000 will also be able to access discounts of up to $4,000, which do not need to be repaid. Renters can access the discounts too, with their landlord's permission.

Each of these upgrades reduces emissions in its own way.

Rooftop solar and batteries let households generate and store clean energy rather than drawing on the grid at peak times. Insulation and draught proofing cut the amount of energy needed to heat and cool a home in the first place. Reverse cycle air conditioning is far more efficient than old gas heaters or resistive electric heaters, and switchboard upgrades make it possible for a home to safely electrify other appliances down the track. Together, these upgrades reduce a household's overall energy demand and shift what remains toward cleaner sources.

Why the combination matters

On their own, each program helps reduce emissions. Together, they reinforce one another.

The Solar Sharer Offer rewards households for using more electricity when the grid is cleanest, while the Home Energy Saver program makes it more affordable to install the solar panels, batteries and efficient appliances that let households take full advantage of that clean, low-cost power. The result is lower bills for households and faster progress toward a renewable energy future.

To find out if you are eligible, talk to your electricity retailer about the Solar Sharer Offer, and visit the Home Energy Saver program page to check eligibility and apply.

Sustainability – no one gets there alone

Never one to miss an opportunity to meet over coffee, I eagerly accepted an invitation to celebrate B Corp Month in March. Eagerly. Then I realised I should do a little homework first — slightly less eagerly.

First things first: the “B” in B Corp stands for “benefit for all.” The idea is that businesses balance purpose and profit, considering the impacts of their decisions on workers, customers, communities and the environment. To achieve certification, companies go through a rigorous process overseen by the global non-profit B Lab. Businesses must assess and publicly report on how they operate — from governance and worker wellbeing to environmental practices and community impact. It is not a once-off exercise either. To keep the certification, companies must repeat the process every three years.

It was a bit of an eye-opener to see this level of scrutiny applied voluntarily by private companies. Several businesses in the Byron Shire have already taken the step. Cape Byron Distillery, best known for Brookie’s Gin, became a certified B Corp in 2022. Stone & Wood Brewing was one of the early Australian breweries to gain certification. Sienna Byron Bay, a sustainable nail-polish brand, has been certified since 2019. Summerland Bank is another well-known regional example.

At first glance, it might seem like there are only a handful of B Corps locally. But in fact, towns such as Byron Bay, Mullumbimby and Ballina have one of the highest concentrations of B Corps per capita in Australia. That raises an interesting question: why here?

Part of the answer lies in the Northern Rivers’ long tradition of community enterprise, environmental awareness and locally driven initiatives. Long before “purpose-driven business” became fashionable, people here were already experimenting with new ways of balancing economic activity with environmental responsibility. In many ways, B Corp certification simply formalises something that has been happening organically in this region for decades.

But the movement has not been without criticism. Last year some commentators argued that the B Corp assessment was too vague and insufficiently regulated, and that the standards were not high enough. In response, B Lab has strengthened its framework and introduced more robust requirements. That is probably healthy. If the idea is to hold companies to higher standards, the framework itself needs to keep evolving.

Which brings us back to the question: to B Corp, or not to B Corp?
Perhaps the real question is bigger than certification.

As Australia moves through the energy transition — shifting from fossil fuels to renewable energy, electrification and decentralised energy systems — regional communities will play an increasingly important role. Rooftop solar, community batteries, local microgrids and new forms of energy sharing are already reshaping how energy is produced and used.

These changes are not just technological. They are economic and social as well.

The transition creates opportunities for local ownership, new business models and community participation in the energy system. Regional economies like the Northern Rivers can become places where innovation happens — where businesses, households and community organisations work together to build resilient local systems.

In that context, the values behind B Corp; transparency, accountability, and balancing profit with wider community benefit, feel particularly relevant. Certification itself may not be the end goal. But the conversation it encourages about what businesses are for, who they serve, and how they contribute to their communities is an important one. And in a region already thinking seriously about climate action, community resilience and the future economy, that conversation is likely to keep growing. So perhaps the real question is not whether every business should become a B Corp. It is whether more businesses, certified or not — are willing to operate as if community benefit matters just as much as profit.

The Better Business Monthly Coffee Catch-up for the Northern Rivers community (northernrivers@bcorp.community) brings together B Corps and B-Curious businesses, and anyone interested in making business better for people and planet. Events are organised by the affable Willem Overbosch from SDG Align, a business that helps organisations turn sustainability into practical action.

Letter to the Hon Penny Sharpe MLC, Minister for Energy and Climate Change from the Community Energy sector of NSW to increase community energy funding within the NSW Consumer Energy Strategy

David Kirkwood — Wed, 06 Aug 2025 06:08:42 +0000

Zero Emissions Byron collaborated with the Coalition for Community Energy on a letter to the Minister for Energy and Climate Change to advocate for a substantial increase in the proposed $5 million community energy fund in the NSW Consumer Energy Strategy.

We requested that at least $28 million of the $280 million Consumer Energy Strategy be allocated to community-led energy initiatives — representing 10% of the total strategy budget — and reflective of the importance of funding at the local level.
