SYDNEY – Thursday 16 May 2024 – Greenpeace Australia Pacific has today welcomed the long-awaited passing of New Vehicle Emissions Standards, which will reduce carbon pollution from cars and kick-start the transition to an Australia that runs on renewables.

“Today we are delighted to learn that New Vehicle Emissions Standards have become law – which means 80 million tonnes less carbon pollution from cars will enter the atmosphere by 2035. That is the same as the entire state of Victoria emits in a year,” Greenpeace Australia Pacific Head of Climate and Energy Joe Rafalowicz said today.

“The New Vehicle Emissions Standards are the first step to opening up the Australian market to more EVs and ensuring that demand for them can be met. This means that finally, Australia can join other countries in accelerating on electric vehicles and bringing down our massive transport emissions.

“Had the Government introduced standards in 2015 when the idea was initially put forward, Australians would have saved almost 6 billion dollars in fuel costs.

“Well done to Prime Minister Albanese for succeeding where others have failed. He stood up to the car lobby and acted in Australia’s best interests.

“Australia should be leading the world on renewables and clean technology like EVs – but just like the car lobby fought tooth and nail to stop these pollution caps for new cars, the chicken littles of the fossil fuel era claim every reform is impossible. They are wrong. The Government proved that today: Australia’s future is zero emission, starting with our cars.

“It’s been a long road, and we’re finally at the finish line. In this critical decade – be it in transport, gas, protecting our environment and our oceans –  we desperately need to see leadership from Labor across the board on climate action,” Rafalowicz added.

Guest post: Greenland ice sheet shrinks for 30th year in a row

Greenland has now marked the 30th consecutive year where it lost more ice than it gained.

Over the 12-month period to August 2026, the world’s second-largest ice sheet lost around 135bn tonnes of ice.

This major ice loss came as the region experienced a relatively cool start to summer and less surface melt than in previous years.

In other words, it was not an “extreme” year for weather in Greenland – and, yet, the ice sheet ended firmly in the red.

Three decades of continuous ice loss in Greenland is significant, given that scientists typically need 30 years of data to separate the “fingerprint” of human-caused climate change from natural variations in the climate.

In Greenland, the direction of travel has been the same – downward – every single year for 30 years.

These latest figures come as a new report highlights that ice melting processes seen for decades in Greenland are increasingly being replicated in Antarctica.

Greenland, therefore, is not only the largest present-day source of ice-driven sea level rise – but offers a preview of what is in store for the world’s largest ice sheet.

(For our previous analyses of Greenland’s ice cover, see coverage in 2025, 2024, 2023, 2022, 2021, 2020, 2019, 2018, 2017, 2016 and 2015.)

Surface mass balance

One way that scientists track the health of the Greenland ice sheet is by tracking changes to its “surface mass balance”.

This is the difference between ice gains from snowfall and losses from melt at the surface of Greenland’s ice sheet.

Greenland’s annual ice cycle runs from 1 September through to the end of August. The surface mass balance at the end of this period has, to date, always been positive, because the surface accumulates more snow than it loses from melting ice.

The ice sheet typically gains mass during the colder months of autumn, winter and spring. Then, as temperatures increase from around mid-June, the ice sheet begins to lose more ice through surface melt than it gains from snow.

(Greenland also loses ice when icebergs break off – or “calve” – into the sea, as well when the front of glaciers melt when they meet warm sea water. These losses are included in the “total mass balance” – see below.)

Greenland ended 2025-26 with an overall surface mass balance of 519bn tonnes.

This is the sixth highest in a dataset stretching back 46 years and about 178bn tonnes above the 1981-2010 average of roughly 350bn tonnes.

The map below shows the difference between the surface mass balance in 2025-26 and the 1981-2010 average, where blue shows ice gain and red shows ice loss.

The blue lines in the charts below show the surface mass balance throughout 2025-26 for individual days (top) and cumulatively throughout the year (bottom). They highlight how Greenland gained ice between September 2025 and May 2026, before starting to lose ice from June onwards.

Total mass balance

Another way scientists measure the health of the Greenland ice sheet is by looking at its “total mass balance”.

This calculation accounts for ice loss at the surface, as well as the calving of icebergs and the melting of glacier fronts where they meet warm seawater. The latter two components are known as the “marine mass balance”.

It also accounts for a small amount of ice melt at the underside of the ice sheet. This is known as the “basal mass balance”.

In recent decades, Greenland’s total mass balance at the end of the ice cycle year has been negative.

The 12 months to August 2026 were no different. Once all these factors are considered, Greenland lost around 135bn tonnes of ice.

We reached this figure using the same method featured in previous Carbon Brief analyses of Greenland ice cover. This approach is based on an average of three climate models.

However, for the first time, this year’s update includes a separate estimate for Greenland ice loss, based on data from one climate model and automatic weather stations, satellites, GPS data and observations from planes.

This approach estimates that the ice sheet lost an even greater 173bn tonnes of ice over 2025-26.

(Scientific estimates for ice loss in Greenland vary because there is incomplete information about how thick the ice sheet is, how fast it is moving as well as the rate at which it is melting at the surface. Scientists use different approaches for accounting for these uncertainties.)

The chart below shows how Greenland’s total mass balance has changed since 1985, featuring the higher 173bn estimate for the last ice cycle year.

It shows how 2025-26 was the 30th consecutive year of ice loss in Greenland, with 1996 the last year that saw an annual net gain of ice.

Surface melt

Winter and early spring in 2025-26 were unusually dry in the southern half of Greenland, leaving around 40bn tonnes less snow on the ice sheet than normal.

Dry winters typically mean high ice melt rates later on, given that heavier winter snowfall often acts as a protective shield that prevents ice loss in the early part of summer.

However, the relatively dry winter was followed by a relatively cool start of summer. Frequent snowfall and extensive cloud cover limited the sun’s ability to warm the surface at the time of year when solar radiation is typically strongest.

The onset of the melt season – the first of at least three consecutive days with melting over more than 5% of the ice sheet – occurred on 5 June, nine days later than the 1981-2010 average.

From the end of June, the weather in Greenland changed markedly, as warm, sunny conditions took hold.

During the first 20 days of July, melting was well above the 1981-2020 average. At its peak on 22 July, melting covered 74.9% of the ice sheet.

(For comparison, July 2025 holds the record for melt area in Greenland, when 81.2% of the continent was melting simultaneously.)

However, the early season fresh snow in June helped to form a cold and bright buffer, reducing the subsequent summer ice melt and runoff.

The map below shows how roughly three-quarters of Greenland’s ice sheet – shaded in red – was experiencing surface melt on 22 July. The chart shows how surface melt on that date (blue line) outpaced the 1981-2010 average (grey line and shading).

Snowfall

As mentioned above, snowfall is the only way for the ice sheet to gain mass.

Because the dry 2025-26 winter did not provide the usual thick layer of snow to act as a protective buffer, the ice sheet started the summer already “behind” on ice levels.
