Welcome to Carbon Brief’s DeBriefed.
An essential guide to the week’s key developments relating to climate change.
This week
Heating up
NOT FREE FROM HEAT: “Dangerous, record-breaking” heat altered plans for 4 July celebrations across the US this weekend, reported the Associated Press. New York and Boston hit 100F (37.8C) on Thursday, said the newswire. CNBC reported that temperatures of up to 105F (40.5C) are forecast in central and eastern parts of the country, with “daily, monthly and all-time records possible”.
TEMPERATURES SOAR: Heat that hit western Europe last week spread east to “scorch” Germany, Hungary, Romania, Poland and others, said Bloomberg. Red warnings for extreme heat were issued in a number of nations, noted the outlet, adding that the heat “underscores how climate change is transforming summers in the world’s fastest-warming continent”. The Independent said last month was confirmed to be England’s hottest June on record.
HEAT DEATHS: June’s extreme temperatures caused more than 2,000 excess deaths in Spain and France, reported the Guardian. The countries are bracing for further heat that “could bring temperatures of 44C (111F) over the coming days”, said the newspaper. Deaths in France rose almost 30% at the heatwave “peak” on the week of 22 June, according to Le Monde. Last week’s conditions also led to around 480 excess deaths in the Netherlands, reported Reuters.
BOILING: Global ocean temperatures reached record levels for this time of year, reported NBC News, “fuelling fears of more dangerous heatwaves this summer and fanning concerns over the escalating global climate crisis”. Scientists told the Financial Times that this could lead the world towards “uncharted territory”. The newspaper said global average sea surface temperatures reached 20.96C on 21 June, exceeding June records for 2023 and 2024.
Around the world
- GOAL DROPPED: The World Bank will “abandon” its goal to devote 45% of annual lending resources to climate-related projects, reported Reuters. Carbon Brief explored what it could mean for global climate action.
- FIVE-YEAR PLAN: China plans to invest more than 20tn yuan ($2.9tn) in “key energy projects and new business models” over the next five years, according to International Energy Net.
- DRILLING: The Guardian said UK Labour politicians “urged” the likely next prime minister Andy Burnham to ignore “deluded” calls to develop the Rosebank oil field located in the Atlantic north of Scotland.
- PLASTIC TALKS: Countries and activists feared key issues could be sidelined at “critical” talks on a global treaty to curb plastic pollution in Kenya, said Climate Home News. A treaty could have “important implications” for climate change, reported Carbon Brief in 2024.
- CANADA PIPELINE: Canadian prime minister Mark Carney announced plans to build an oil pipeline to supply Asia with up to 1m barrels per day, reported the Financial Times. Earlier this week, Carney called the previous government’s climate plans “expensive” and “divisive”, said CBC News.
63
The number of UK newspaper editorials calling for more oil and gas extraction in the North Sea so far in 2026, according to Carbon Brief analysis.

Captured
Wind and solar were the world’s largest source of new energy in 2025, according to Carbon Brief analysis of the latest Energy Institute statistical review of world energy. Wind and solar also saw the fastest growth, up by 18% in 2025. Nevertheless, every source of energy – including coal, oil, gas, nuclear and hydro – also reached global all-time highs last year.
Spotlight
Vietnam’s EV surge
Carbon Brief explores the reasons behind soaring electric-vehicle sales in Vietnam.
Motorbikes are a constant fixture on streets across Vietnam. They pollute the air in cities and make crossing the road a feat of endurance.
But, increasingly, people are moving away from petrol-powered vehicles to save money and reduce air pollution.
Sales of electric motorbikes, scooters and mopeds more than doubled in Vietnam last year, according to a recent report from the International Energy Agency (IEA).
This identified that Vietnam has the largest electric vehicle (EV) market in south-east Asia.
Nearly one-in-five of the two-wheeled vehicles sold last year were electric, it noted, in a nation with 102 million people and 77m motorbikes.
This is “particularly impactful” given they are the main mode of transport in Vietnam, said Lam Pham, Asia energy analyst at thinktank Ember. He told Carbon Brief:
“Electrifying road transport is essential for Vietnam to achieve its net-zero target by 2050. Road transport accounted for around 86% of transport-sector emissions in 2022.”
The nation has just 6.8m cars, but this number is also climbing, partly due to EVs, with nearly 40% of new car sales being electric.
This is “above levels seen in most European countries”, noted the IEA. (The UK’s figure is around 30%.)
EV incentives
Fuel costs surged in south-east Asian countries earlier this year after the energy crisis caused by the US-Israel war on Iran.
This “accelerated” discussions from “why use EVs” to “why keep paying more for fuel”, said Dr Tham Nguyen, a lecturer at the Ho Chi Minh City campus of Australia’s Royal Melbourne Institute of Technology (RMIT) University, who has researched Vietnamese public attitudes to EVs.
But the surge is “not driven by fuel prices alone”, noted Pham.
Increased EV sales can also be attributed to a “convergence of affordability, convenience and sustainability”, Nguyen said:
“Vietnamese consumers buy EVs because they see real value with immediate personal benefits, such as cost savings and energy security, alongside long-term environmental gains.”
Government policies have also incentivised sales through registration fee exemptions and tax cuts for EVs.
Another factor is affordable EVs sold by Chinese companies and Vinfast, a Vietnamese manufacturer. The IEA report noted that Vietnam is the only country in south-east Asia with “sizeable” domestic production of accessible EVs.
Vinfast reported a 219% year-on-year increase in orders for electric motorbikes and e-bikes in the first quarter of 2026, but the company has yet to turn a profit.
Pham noted that “growing public awareness of air pollution” has also “dramatically strengthened” public support for EVs.
Future plans
Vietnam’s major cities also have plans to get drivers to go electric or turn to public transport.
The capital city Hanoi announced that it would ban fossil-fuel-powered motorbikes from a central zone this month, but this has been postponed until 2028.
Ho Chi Minh City, the nation’s largest city with more than 9.5 million people, intends to introduce low-emission zones and swap 400,000 petrol-powered motorbikes to electric by 2028.
The city’s green transport plans focus on metro lines, electric buses and e-bikes, explained RMIT associate professor Catherine Earl. She noted that walking and cycling are currently “not popular, accessible or safe for many residents in Ho Chi Minh City’s hot and humid climate”.
Looking ahead, Pham said Vietnam could focus on “purchase subsidies, financing schemes and adequate charging or battery-swapping infrastructure, to ensure lower-income riders, including delivery and ride-hailing drivers, are not negatively affected”.

An older teaching about land acknowledgement
As I have come to understand the spirit and intention of land acknowledgement, I often return to fond memories of my grandmother and her words of wisdom. She taught that the health of the places we call home comes first, because the wellbeing of the people depends on it.
In her teaching, land acknowledgement began with the land. Long before it became a paragraph read at the start of a meeting, it was a way of recognizing a homeland: its waters, its species, its seasons, and the spirit that revealed whether the place was well.
Her teaching echoes a practice found across many Indigenous Nations. Haudenosaunee gatherings, for example, have long opened with the Ohén:ton Karihwatéhkwen, the Thanksgiving Address, often translated as “the words that come before all else.” The speaker greets and gives thanks to the people, the earth, the waters, the plants, the animals, the winds, the sun, the moon and the stars. Only after everything that sustains life has been acknowledged does the gathering turn to its own business.
That order changes what an acknowledgement is for. Its purpose was to share the story of a place with neighbours and to draw them into the work of tending it. People entered the story second, as the ones responsible for what had just been named.
Understood this way, an acknowledgement does more than open a meeting. It asks us to reconsider where we stand, and what we owe the ground beneath us.
Nations among nations
In her teaching, people are one nation among many. The salmon are a nation. So are the cedars, the bison, the medicine plants, and the pollinators. Each belongs to a place, carries its own responsibilities, and offers gifts no other nation can give.
This idea of kinship runs through many Indigenous philosophies. The phrase “all my relations,” heard in ceremonies and gatherings across Turtle Island, is a reminder that family extends beyond people to the animals, plants, waters and lands that make life possible. Some Indigenous languages carry the same understanding in their grammar, speaking of many plants, animals and natural forces as living beings rather than objects.
Sovereignty, understood through this relationship, is a kind of standing more than a form of control. Each nation belongs fully to its place and carries its share of that place’s life. No nation thrives alone, and none thrives by taking over the whole.
The land is also the source of instruction. Over generations, people watched how a river valley or a stretch of prairie kept itself well: who arrived when, who fed whom, and how much could be taken before the giving stopped. In my grandmother’s telling, those observations became instructions, and those instructions helped shape law and protocol. They guided when to harvest, where to camp, how to enter a neighbour’s territory, and what was owed in return.
Indigenous legal scholars today often describe this as law that comes from the land itself, learned by watching how living systems sustain one another. A plainer name for it is knowing how to live somewhere.
The host and the guest
One of the clearest teachings in this understanding of the world is the relationship between host and guest. My grandmother invited us to recognize that relationship in the lives of plants and animals.
A host prepares the place before anyone arrives. A beaver family dams a stream, and the pond becomes a home for fish, frogs, birds and plants. A fallen tree becomes a nurse log, feeding the next generation of seedlings as it returns to the soil.
A host offers first. A flowering plant sets out nectar. A berry bush ripens fruit. These provisions come in their own season, not whenever a visitor happens to want them.
A host also makes its presence known. Birdsong, scent and the marks left along a trail tell newcomers that a place is already inhabited. The visitor does not arrive in an empty world.
The guest has responsibilities too. A guest attends to the season and to what the place can offer. A guest does not assume that everything within reach is theirs to take. A guest leaves something that helps sustain the relationship.
A bee takes nectar and carries pollen. Read through this teaching, that exchange offers an image of visiting well: receiving a gift while helping the host continue its life.
Many Indigenous harvesting protocols carry the same ethic into daily practice: ask before taking, take only what is needed, offer thanks, and leave enough for others and for the plant or animal to recover.
None of this suggests that every relationship in nature is peaceful or generous. These are ways of seeing responsibilities that people can learn to carry.
Everyone is both
No being is only a host or only a guest.
A tree makes room for other life while depending on soil, water, sunlight, fungi, and relationships beyond itself. People, too, may welcome others into their homes while remaining dependent on the larger homeland that sustains them.
The distinction between host and guest is therefore about roles, not ranks. Everyone receives. Everyone has something to give.
The question is whether the exchange sustains the place.
A visitor who takes without restraint leaves less for those who come next. A host who neglects the place has less to offer. Both have responsibilities, and neither can fulfil them alone.
This is the heart of reciprocity, a principle found across Indigenous philosophies: relationships stay healthy when gifts move in both directions. The Haudenosaunee teaching of the seventh generation extends that exchange across time, asking that decisions made today leave the place well for those not yet born.
Mutual benefit begins here, with the recognition that different beings carry different gifts and obligations.
What people carry forward
My grandmother’s teaching connects these relationships to the ways people meet their neighbours.
The host prepares a place, offers food and rest, and explains where the visitor has arrived. The guest makes themselves known, explains why they have come, listens to the terms of the visit, and brings something in return. The gift may be material. It may also be labour, knowledge, news, or a commitment to help.
Nations around the Great Lakes carried this ethic into treaty. The Dish with One Spoon, an agreement among the Haudenosaunee, Anishinaabe and allied Nations, describes shared hunting grounds as a single dish. Everyone eats from it with one spoon, takes only what they need, leaves enough for others, and keeps the dish clean. The Two Row Wampum, between the Haudenosaunee and European newcomers, shows two vessels travelling side by side on the same river, each keeping its own ways and neither steering the other.
In this understanding, acknowledgement is more than naming the people associated with a territory. It is learning enough about a homeland to behave responsibly within it.
Whose home is this? What sustains it? What laws and agreements guide our presence? What can we receive, and what must we return?
These questions make acknowledgement a relationship rather than a recital.
They also make it diplomatic. A guest who recognizes the host’s homeland recognizes that they have entered a place with its own relationships and responsibilities. A host who welcomes the guest makes room for an encounter governed by those relationships.
Neither arrives without standing. Neither arrives without obligations.
Beginning with place
I write from the shores of the Bay of Quinte. Here, the teaching asks me to begin with the water, the shoreline, and the life they sustain. Before I describe myself, I must attend to where I am.
That does not make people or history less important. It places them within the homeland that gives them meaning. The people, their laws, their agreements, and their responsibilities all belong to the place.
In a time of longer fire seasons, troubled waters, and uncertainty about what the next season will bring, this teaching asks something difficult and useful of us: pay attention before you speak.
An acknowledgement cannot tell the story of a place if the speaker has stopped noticing it.
The land came first. Beginning there again means learning to name what sustains us, and accepting that what sustains us also asks something of us.
