Recent severe weather and reports on climate targets have brought more people here seeking reassurance about our efforts to address climate change. Please use this weekly thread for those discussions.
Climate change is a serious, compounding problem, and concerted action can make an enormous difference.
We can already see that difference in the long-term outlook. Climate Action Tracker’s current-policy projection improved from around 3.6°C of warming by 2100 in its 2015 assessment to around 2.6°C in its November 2025 assessment.
The 4°C world quietly stopped being the forecast
That represents an enormous amount of potential harm avoided. Further progress can change the outlook again.
And the acceleration we have been discussing is becoming increasingly visible: electric vehicles taking over entire national markets, factories adding shifts to meet demand, households installing batteries, and cleaner technologies reaching further into industry.
These developments reinforce one another. More clean electricity makes electrification more valuable. More batteries make renewable electricity available when people need it. Growing markets support manufacturing, infrastructure and the next wave of adoption.
Global fossil-fuel CO₂ emissions are projected to fall in 2026
Carbon Brief projects that global fossil-fuel CO₂ emissions will fall by around 0.5% this year.
The fossil-fuel price shock is reducing demand and increasing the incentive to switch. Households, businesses and governments have alternatives available on a scale that did not exist during earlier energy crises.
An electric car bought today, a solar installation completed this year or a factory converted to electricity can keep displacing fossil fuels long after the immediate crisis has passed.
This week’s stories show those changes spreading.
Good news shared over the last week
Denmark offers a remarkable glimpse of what happens as electric vehicles become the normal choice.
Statistics Denmark reports that fully electric cars accounted for 88.6% of new registrations in September. Among households, their share reached 97.3%.
Almost every new car entering the household market was electric.
And the accumulated effect is now substantial: Denmark had 718,300 electric passenger cars at the end of September, representing 24.2% of its entire passenger-car fleet.
That fleet grew 47.5% in a year, adding more than 231,000 electric cars.
This is what the tipping process looks like as it moves from new purchases into the vehicles people actually drive. Nearly a quarter of the country’s cars can already run without petrol or diesel.
France’s transition is also changing what manufacturers build.
Renault’s brand chief told Reuters that electric cars represented around 60% of its French sales during the preceding weekend.
The broader monthly figures were already striking: electric cars accounted for 53.5% of Renault’s French registrations in September.
To meet demand, Renault added another half-shift at Douai at the beginning of October. The factory, which produces the electric Renault 5, Mégane and Nissan Micra, now operates across three shifts.
This is an important connection. Rising demand changes factory schedules, employment and production plans. The transition gains industrial capacity behind it.
More customers are choosing electric cars, and manufacturers are responding by making more of them.
Australia is building the storage to make its solar fleet more useful.
SunWiz figures reported by ESS News estimate 966.5 MWh of home batteries installed in September, up 12.5% from August.
That is almost a gigawatt-hour of additional household storage in a single month.
The battery programme is also helping drive solar installation. Australia registered 311.8 MW of small-scale solar in September, and its January–September total was 43% ahead of the same period in 2025.
By the end of September, more small-scale solar had been installed during 2026 than in the whole of 2025.
Solar and batteries are helping each other spread. Panels give households electricity to store; batteries let households use more of that electricity after sunset.
The 2025-to-2026 acceleration is showing up on rooftops and in homes.
India is expanding the factories that supply the transition.
Mercom’s latest manufacturing figures, reported by pv magazine, show that India added 50.6 GW of annual solar-module manufacturing capacity and 9.7 GW of cell manufacturing capacity in the first half of 2026.
By June, total module manufacturing capacity had reached 261.7 GW, alongside 36.6 GW of cell capacity.
Those figures describe the factories’ potential annual production, showing how much industrial capacity is being assembled behind future deployment.
Building a cleaner energy system creates demand for manufacturing. Building manufacturing gives countries more capacity to supply that cleaner system.
India is developing both sides of that relationship.
The same pattern is visible across the wider world.
DNV’s new Energy Transition Outlook finds that the non-fossil share of primary energy increased more than three times as much in major energy-importing regions as in exporting regions over the past five years.
The increase was 2.2 percentage points across China, India and Europe, compared with 0.7 points across the Middle East, North America and Russia.
DNV also reports that installed battery capacity has increased fourteenfold in five years.
For energy importers, clean electricity offers a compelling combination: domestic production, lower exposure to fuel-price shocks and less money spent continually buying replacement fuel.
That gives the transition support from energy security and industrial policy as well as climate action.
Countries have several reasons to keep building.
Rystad Energy’s new global assessment captures how rapidly parts of the market are moving.
Its Global Energy Scenarios 2026 report says electric vehicles reached around 33% of global car sales in the middle of the year.
Chinese battery-electric exports to Europe approached one million vehicles during January–July, roughly double the same period in 2025. Exports to South America rose to around half a million, from approximately 170,000.
Rystad expects battery storage to grow around 56% this year, and electric trucks to exceed 40% of Chinese heavy-truck sales.
The report describes global fossil CO₂ emissions as plateauing near 40 billion tonnes. Its reference scenario, which assumes gradual policy strengthening, then has emissions falling to around half that level by 2050.
The encouraging connection is between today’s market growth and the machinery that will determine tomorrow’s fuel demand.
Cars, trucks and batteries are being purchased now. Those purchases help change the energy system for years.
Electrification is also reaching further into industrial heat.
Fraunhofer ISE reports testing high-temperature heat pumps supplying process steam at temperatures up to 160°C.
Its work combines laboratory testing with operational monitoring of five large heat pumps in German district-heating networks.
The purpose is practical: improve the equipment, controls and integration needed to replace fossil-fuel heat in factories and heating systems.
Steam and hot water are essential industrial services. Extending heat pumps into those applications expands the range of activities that can run on increasingly clean electricity.
The transition is reaching beyond the most visible technologies into the heat that keeps industry working.
There are also substantial opportunities in equipment we already use.
A story shared this week highlighted variable-frequency drives, which adjust electric motors’ speed to the work required.
The underlying Berkeley Lab assessment estimates that motor systems consume around 29% of US electricity.
It identifies potential annual electricity savings worth $13.2 billion from better matching motors to their tasks through appropriate sizing and speed controls.
Pumps, fans and compressors operate throughout factories, offices, schools and hospitals. Improving them can reduce operating costs while freeing electricity and grid capacity for other uses.
A great deal of climate progress is available through applying existing engineering knowledge across millions of ordinary machines.
A California theme park provides a particularly visible example of combining solutions.
Six Flags Magic Mountain has installed a 12.37 MW solar carport, alongside 8 MWh of battery storage and 109 charging connectors.
The canopies shade around 4,315 parking spaces.
Expected annual generation is approximately 20.8 million kWh, enough to offset the annual electricity consumption of Magic Mountain and neighbouring Hurricane Harbor Los Angeles.
The same space now provides parking, shade, electricity generation and charging.
Projects like this make the connections easy to see. Solar produces electricity where people already gather, batteries extend its usefulness, and charging helps vehicles use it.
A large parking area becomes part of the energy system.
Portugal’s Guimarães shows how cities can make adaptation part of everyday improvements.
The European Green Capital is connecting parks, restored waterways, farmland and forests through a network of green corridors.
Researchers studying a decade of satellite imagery found land-surface temperature reductions of up to 2.49°C in areas where green roofs and urban gardens were introduced.
The city is also improving access to riverbanks and connecting green spaces so people can use them.
These changes bring benefits people can experience directly: shade, more pleasant walking routes, access to nature and cooler surfaces.
Adaptation can make neighbourhoods better places to live while helping them cope with heat.
In Nigeria, women working with Lokiaka have restored 190 hectares of mangrove forest—a reminder that damaged landscapes can recover through sustained community work.
There is also a useful resource for helping practical projects win support.
Columbia University’s Sabin Center has published a report addressing 38 false claims about solar, wind, electric vehicles and battery storage.
Shared this week, it gives readers a reference for conversations about technologies increasingly appearing in their own communities.
People supporting a local solar project, discussing electric vehicles or helping shape community decisions have more evidence available to them.
Sharing reliable information is one practical way to help solutions spread.
The bigger picture
The most encouraging feature of these stories is how many connections are becoming visible.
Electric-car demand is changing factory production. Batteries are encouraging households to add solar. Solar installations are supplying charging. Industrial research is expanding the uses for clean electricity. Efficiency improvements can make room for further electrification.
As these markets grow, they develop more suppliers, skilled workers, infrastructure and customers. More people and businesses gain a direct interest in keeping the transition moving.
We are watching parts of the energy and transport transition reach tipping points, at different speeds across different markets.
The acceleration is already visible between 2025 and 2026. The opportunity is to help it spread further, bringing more communities and more parts of the economy into that progress.
The biggest misconception I keep seeing is that nothing is being done. Look at what is already being built, bought and used.
There are concrete reasons for hope, and concrete opportunities to contribute.
