Amid reports that the government could weaken the UK’s electric vehicle (EV) targets, Carbon Brief analysis reveals the nation’s EV drivers are saving more than £1,100 a year in fuel costs, compared with running a petrol car.

Battery EVs (BEVs) are roughly four times more efficient than combustion-engine cars, making them far cheaper to run – particularly since the Iran crisis caused a spike in fossil-fuel prices.

The savings from driving BEVs are also more than three times higher than for “plug-in” hybrids (PHEVs), which evidence shows are mostly driven with their combustion engines.

In total, the more than 2m BEVs, 1m PHEVs and 100,000 electric vans on UK roads are saving drivers around £3bn a year, Carbon Brief’s analysis shows, as illustrated in the figure below.

In addition, these EVs are avoiding the need for nearly 2.5bn litres of fuel and cutting carbon dioxide (CO2) emissions by nearly 7m tonnes each year.

Despite recent news that EVs are now cheaper to buy than petrol cars, as well as having far lower running costs, BBC News says the government is “set to water down” its EV sales targets.

The broadcaster explains that the current goal, under the UK’s “zero-emissions vehicle” (ZEV) mandate, is for 80% of new car sales to be BEVs by 2030.

It says that the government is set to consult on weakening this to between 50% and 70%, following “lobbying” by carmakers and trade unions.

According to the Sunday Times, prime minister Keir Starmer “is understood to have overruled the energy secretary [Ed Miliband] after sustained pressure from industry, the Unite union and Peter Kyle, the business secretary”.

The car industry has consistently claimed there is insufficient demand for BEVs to meet the targets under the ZEV mandate, yet the government says manufacturers have “over-complied” to date. Independent analysts say the industry is on track to continue beating the ZEV mandate goals.

The industry has been able to beat its targets by using a wide range of “flexibilities”, which were introduced after a previous round of lobbying. These allow carmarkers to meet part of their EV targets by selling more efficient combustion cars, such as hybrids and plug-in hybrids.

The ZEV mandate is the single-largest part of the government’s plans to meet its legally binding climate goals over the next decade.

The advisory Climate Change Committee (CCC) previously warned that the extra flexibilities would result in a larger number of hybrids being sold, at the expense of battery EVs.

When it consulted on the ZEV mandate in 2023, the then-Conservative government noted that PHEVs do not deliver the cost and CO2 savings they are advertised with.

It pointed to “dramatic” differences between the performance of PHEVs in test cycles and what they deliver under real-world conditions.

In practice, less than a third of miles driven in PHEVs are fuelled by electricity, with petrol making up the rest. As a result, cost and CO2 savings from BEVs are three times larger than for PHEVs.

REPORT: WA Clean Energy, Jobs & Industry Plan

Published

on

Prepared by a coalition of nine Western Australian union, industry, conservation, and community organisations—including UnionsWA, the Conservation Council WA, and the Smart Energy Council—the WA Clean Energy, Jobs & Industry Plan provides a practical roadmap to transform Western Australia into a clean energy powerhouse while creating thousands of secure local jobs.

Western Australia stands at a pivotal crossroads: lead the global clean energy economy or watch investment, future industries, and secure jobs go elsewhere. The WA Clean Energy, Jobs & Industry Plan outlines a transformative blueprint to harness the state’s world-class solar and wind resources. Discover how legislated renewable targets, green iron manufacturing, and a dedicated regional training strategy can generate tens of thousands of local jobs, lower household bills, and build a resilient, net-zero future for all Western Australians.

WA needs a clear and forward-thinking plan if it is going to become a competitive renewable energy powerhouse and maintain its economic strength through the energy transition.
“Western Australians know a faster renewable energy transition will lower their household expenses and prevent harmful climate pollution. But the community also needs clear direction to ensure this transition will create jobs, lower costs and not cause undue environmental harm.
“Here, sectors representing a broad range of interests have laid the groundwork for those outcomes, clearly outlining what is needed to create a future for WA that is good for the environment, for the climate, for workers and for the economy.

Summary

  • Creating local employment.
  • Maintaining industrial competitiveness.
  • Lowering household energy costs

To realize this vision, the framework details actionable measures to follow on from the recent WA Government announcement of a 75% Renewable Energy Target by 2031 for the South West Interconnected System. This includes developing a statewide Renewable Energy Target, coordinating statewide workforce and training pipelines, strategically planning regional infrastructure to safeguard high-value biodiversity and cultural heritage, and ensuring equitable benefit-sharing through household electrification incentives and First Nations equity partnerships. Ultimately, the plan highlights that establishing clear policy and regulatory certainty will unlock lower energy bills, boost power reliability, and secure the state’s global competitiveness in emerging green commodity export markets.

Key Findings

  • Statewide Renewable Energy Target and Emissions Reduction Targets: The report calls for a statewide RET and 1.5°C aligned emission reduction targets to remove policy risk, lower capital costs, and attract clean energy investment.
  • Transformative Job Creation: Accelerating the transition offers massive employment prospects, including up to 8,800 solar and battery jobs by 2050, as well as 24,000 ongoing and 11,000 construction jobs in a commercial green iron industry.
  • Industrial Electrification & Competitiveness: Requiring large gas users to adopt binding electrification timetables and providing concessional financing will protect existing energy-intensive manufacturers from rising energy costs and impending domestic gas shortfalls.
  • Green Commodity Export Leadership: Western Australia can build new export markets in green iron, green ammonia, and offshore oil/gas decommissioning by constructing shared common-user infrastructure and setting dedicated Green Commodity Export Targets.
  • Coordinated Workforce & Training Pipeline: To address critical skill shortages the plan recommends establishing a WA Clean Energy Jobs Plan 2050, three regional training hubs, and dedicated pathways for female and under-represented apprentices.
  • Environmental Safeguards & Community Benefits: Fast-tracked development must be paired with State Planning Policies that avoid high-biodiversity and cultural heritage lands, mandate new data centres to run on additional renewable power, and deliver household electrification rebates and First Nations equity partnerships.

COP17: Key outcomes agreed at the UN biodiversity conference in Yerevan

Published

on

Article Contents

Countries have completed the first “global review” of their progress towards reversing nature loss by 2030 at the COP17 biodiversity talks in Yerevan, Armenia.

The review “notes with deep concern” that, unless action is “rapidly accelerated”, the goal to reverse nature loss and meet a set of 23 targets by 2030 “will not be achieved”.

It “urges” countries to accelerate action, including by “increased ambition in addressing the gaps”.

Much of the discussions in Yerevan focused on how to raise the necessary funds to help developing countries protect nature.

Some major economies pushed to expand the range of nations that are expected to provide finance, with countries agreeing at the end of the two weeks of talks that non-donors that want to contribute can “signal interest” before COP18.

This came after developed countries failed to meet a target to significantly ramp up nature finance over the last few years.

It also came as a landmark fund agreed at COP16 in Colombia to pay communities for the genetic resources derived from nature stands nearly empty two years on.

The Yerevan talks marked the halfway point of the “Kunming-Montreal Global Biodiversity Framework” (GBF), the “Paris Agreement for nature” first made in 2022 and due to be achieved by 2030.

During the nearly 12-hour-long final plenary, countries voted for Quito, Ecuador, to host the COP18 nature talks, which will be held in 2028.

Countries managed to sign off on all the major negotiation texts, marking a stark contrast to COP16, which ran so far over time that the Colombian presidency lost “quorum”, forcing talks to resume in Rome months later. 

Below, Carbon Brief has detailed analysis of all of the key outcomes from COP17.

Formal negotiations

Finance

Finance, predictably, was at the heart of the discord and deadlock at the Yerevan talks.

At COP17, discussions on finance had to achieve several outcomes.

The first part – to take stock of biodiversity finance mobilised so far to meet the nature deal’s goals – fell under the global review.

As the global report noted, developed countries failed to meet their commitments to raise “at least $20bn a year by 2025” for nature. Delegates pointed to falling aid levels and a sharp 27% decline in environmental funding for the 2026-30 period.

The second part was to agree on how to mobilise resources for the next four years, to meet the GBF’s goals and targets.

Calls to “broaden the contributor base” of who pays to protect nature – and whether that should include emerging economies – became the most fraught element of the talks.

Eventually, countries agreed on what Switzerland described as a “super, mega-delicate” text. It hinged on major “political compromises”, with “no major winner or loser”, according to Kenya. 

Per the decision, countries that want to be included on a list of developed country donors can “signal interest” through bilateral, confidential consultations before COP18 and every alternate COP after.

Finally, countries also agreed on criteria to shape and resource a new, permanent financial mechanism to protect nature after 2030.

However, this did not immediately take the form of a new fund under the COP that biodiverse countries have demanded since 2022, deferring the mechanism’s institutional structure to COP18.

Resource mobilisation discussions at the GBF’s halfway mark were supposed to agree on how to close the “biodiversity finance gap” and to “increase resources from all sources” to “at least” $200bn per year by 2030, as set out in target 19 of the GBF.

The talks were largely dominated by a push, led by the JUSCANZ bloc of developed countries, to “broaden the contributor base”. This could see emerging economies, such as Qatar, China, Saudi Arabia and India, being added to the list of countries
