Net Zero in Retreat:

Why the Isle of Man Must Reconsider Its Climate Commitments

As global powers re-calibrate their climate strategies, the Isle of Man stands at a crossroads.

The Climate Change Act 2021, passed with sweeping ambition, binds the Island to legally enforceable Net Zero targets and costly decarbonisation pathways.

But with mounting evidence that these policies are damaging trade, inflating energy costs, and undermining industrial competitiveness, it’s time to ask:

is this legislation still fit for purpose?

Across the G20 and beyond, governments are rowing back on Net Zero pledges.

The United States, under President Donald Trump, has led the charge—dismantling green incentives and rejecting global carbon frameworks.

Meanwhile, other major economies are delaying targets, expanding fossil fuel use, and prioritising economic resilience over climate idealism.

G20: Cracks in the Climate Consensus

The G20, which accounts for over 80% of global CO₂ emissions and 85% of global GDP, was once the engine of climate ambition. Today, it’s a patchwork of retreat and recalibration:

• India continues to expand coal capacity, resisting binding Net Zero timelines in favour of energy access and industrial growth.
• Brazil has weakened deforestation enforcement, despite its role in global carbon sinks.
• Russia and Saudi Arabia remain anchored to fossil fuel exports, with minimal structural reform.
• South Africa and Indonesia have delayed coal phase-outs due to domestic energy needs.
• Even climate leaders like Germany and Canada face internal backlash over energy prices and grid instability.

A recent European Commission analysis warns that no G20 country is on track to meet the Paris Agreement’s 1.5°C goal. Even with full implementation of current pledges, some net zero activists claim the world is headed for a 2.3–2.6°C rise by 2100.

The ambition gap is widening—and the political will is faltering.

United States: Strategic Retrenchment

The United States has taken a decisive step away from Net Zero orthodoxy. In early 2025, President Trump issued an executive order dismantling key provisions of the Inflation Reduction Act (IRA), which had offered generous tax credits for clean energy, electric vehicles, and household efficiency.

These rollbacks include:

• Phasing out EV subsidies and clean energy tax credits
• Repealing incentives for battery storage and grid upgrades
• Scaling back federal support for solar and wind infrastructure

In August 2025, the U.S. formally rejected the International Maritime Organization’s Net-Zero Framework, calling it a “global carbon tax” that unfairly penalises American shipping and energy sectors. The administration’s stance is clear: energy sovereignty and industrial competitiveness take precedence over climate diplomacy.

Corporate America is following suit. ESG reporting is being quietly dropped, sustainability teams downsized, and climate disclosures rolled back. The Securities and Exchange Commission has relaxed its climate rules, signalling a broader retreat from regulatory pressure.

The Green Energy Cost Myth: A British Reality Check

Contrary to popular belief, green energy is not always cheaper—especially when viewed through the lens of real-world costs in the UK.

In 2025, the average levelised cost of electricity (LCOE) paints a more nuanced picture:

While solar and onshore wind appear cheaper on paper, these figures exclude critical hidden costs:

• Grid upgrades to accommodate intermittent supply
• Battery storage, which adds £0.004–£0.012/kWh depending on capacity
• Curtailment costs when excess energy cannot be used or stored
• Subsidy burdens, often passed on to consumers via levies

According to the UK Government’s own Energy Trends and Prices report, renewables provided 44.4% of electricity generation in early 2025—but this came with a 16% drop in output compared to the previous year, largely due to weather variability and grid constraints.

Meanwhile, fossil fuels—particularly natural gas—remain the backbone of reliable supply, with gas generation up 36% in the same period.

Here’s your comparative graph showing both the Levelised Cost of Electricity (LCOE) for new-build generation and the real-world delivered cost from existing infrastructure across key energy sources:

⚡️ Comparative Energy Cost (2025): New-Build vs. Existing Infrastructure

Key Insights

• Renewables appear cheaper on paper, but their real-world costs are higher due to intermittency, grid upgrades, and storage requirements.
• Fossil fuels show higher LCOE because new plants face carbon pricing and regulatory costs—but existing infrastructure delivers power more cheaply and reliably.
• Natural gas and coal remain cost-effective in practice, especially in regions like the Isle of Man with limited renewable storage and grid flexibility.

This data underscores why policy decisions based solely on LCOE can be misleading.

For the Isle of Man, where affordability and reliability are paramount, real-world delivered cost should be the guiding metric—not idealised projections.

China’s Industrial Surge: A Stark Contrast

While Western nations tighten environmental regulations, China continues to expand its industrial base:

• It remains the world’s largest emitter and is building new coal plants at scale.
• Its dominance in solar panel and battery manufacturing means Western green transitions often rely on Chinese supply chains—undermining energy sovereignty.

This asymmetry raises a critical question: why should the Isle of Man hamstring its own industries while global competitors surge ahead?

What This Means for the Isle of Man

The Climate Change Act 2021 mandates sweeping changes—banning fossil fuel heating systems in new builds, imposing costly energy transitions, and allocating tens of millions in public funds to Net Zero initiatives.

This approach may have been politically fashionable in 2021.
But in 2025, it looks increasingly out of step with international trends and economic realities.

Repealing or amending the Act would not mean abandoning environmental responsibility. It would mean restoring strategic balance—allowing the Island to pursue sustainability on its own terms, without sacrificing affordability, resilience, or industrial viability.

Support for Net Zero is in decline

The Isle of Man’s Minister in charge of environmental policy is Clare Barber MHK.

Barber’s assertion of strong public support may be more aspirational than evidential.

Despite Minister Clare Barber’s assertion of “significant support” for the Island’s Net Zero goals, the data she released in response to Jason Moorhouse MHK paints a picture of steadily declining public enthusiasm.

The reality is that Net Zero enthusiasm appears to be softening—especially as costs rise, deliverables stall, and global peers retreat from rigid climate mandates.

In 2019, 92% of respondents backed community renewable energy projects, and 86% supported installing renewables before 2030—figures that reflected strong early optimism. By 2021, that support had softened, with 80% of people considering climate change an important issue, but no longer expressing direct endorsement of specific Net Zero measures.

Most tellingly, the most recent data from 2024 shows just 56% of ‘respondents’ believe the Government should be doing more to reach its Net Zero target—a sharp drop that suggests growing scepticism, fatigue, or shifting priorities among the public.

Far from confirming consistent support, the trend indicates a clear erosion of consensus.

For policymakers and advocates, this presents a strategic inflection point. Rather than doubling down on a potentially unpopular and economically burdensome framework, the Isle of Man should consider:

• Commissioning independent polling to assess current public sentiment
• Re-evaluating the Climate Change Act’s legal mandates in light of missed targets
• Prioritising energy affordability and infrastructure resilience over ideological timelines

A Call for Pragmatism

Middle MHK Stu Peters has already called for an urgent review of the Island’s Net Zero targets. Peters wants to see a referendum to be held at the time of the next Isle of Man General Election.

He’s not alone. Across Tynwald and the community, voices are emerging that question whether the current trajectory is sustainable—or whether it’s time to change course.

The Isle of Man has always prided itself on independent thinking. Now is the moment to apply that principle to climate policy.

Let’s ask: are we chasing ideals at the expense of livelihoods? And if so, do Tynwald Members have the courage to act?
