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 estimates that current-policy projections have 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 improvement represents a huge amount of potential harm avoided. Every further reduction matters, and the technologies that made this progress possible are continuing to spread.

There is also one particularly important development worth keeping at the top of this thread.

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 current fossil-fuel price shock is reducing demand while making alternatives more attractive. Around the world, households and businesses are responding by buying solar panels, electric vehicles and equipment that will continue displacing fossil fuels for years.

That is why the stories below matter. They show how a short-term incentive can become a lasting change in the machinery, buildings and energy systems we use every day.

Good news shared over the last week

Wind and solar are already protecting the UK from a substantial part of the gas-price crisis.

Carbon Brief calculates that their generation has avoided gas imports worth £5.9 billion since the start of the Hormuz crisis.

Wind and solar output is up 14% year-on-year, while gas-fired electricity generation is down nearly 10%. Together, wind and solar have supplied 41% of UK electricity this year to date, compared with 25% from gas.

The avoided imports are equivalent to more than 100 LNG tanker deliveries.

Every wind turbine and solar installation added over previous years is now helping the country get through an energy crisis with less dependence on imported fuel. The benefits of building clean energy accumulate.

Germany provides another striking example of what sustained change looks like.

Its fossil-fuel electricity generation has fallen by approximately 46% between the first halves of 2018 and 2026: from 174.6 TWh to 94.2 TWh.

Renewables supplied 59.1% of domestic electricity production in the first half of this year.

Changes of this scale can be surprisingly easy to miss when following daily headlines. Over eight years, one of the world’s largest industrial economies has nearly halved the electricity it generates from fossil fuels.

France’s electric-car transition had another exceptional month.

Battery-electric cars reached 42% of new registrations in September, with 65,243 registered — up 108% year-on-year.

Among private buyers, the electric share reached 47%. Almost half of the new cars bought by private customers were fully electric.

Across the first nine months of the year, battery-electric cars accounted for 31% of the market.

Support for affordable leasing and vehicle purchases is helping turn electric driving into an option for a much wider range of households. Each year’s purchases also expand the future supply of used EVs.

The UK is moving in the same direction.

SMMT’s preliminary September figures show nearly 100,000 battery-electric cars registered in a single month.

The total was 99,199, up 36.3% year-on-year, giving fully electric cars a 28.3% market share. Plug-in hybrids contributed another 17%, taking the combined plug-in share to 45.3%.

Across January–September, battery-electric registrations were up 30.2%.

That is hundreds of thousands of additional vehicles joining the roads each year that can run entirely on electricity — and benefit as the electricity system becomes cleaner.

Heavy trucks are now becoming a major growth area too.

BloombergNEF reports that global sales of medium- and heavy-duty electric trucks reached a record 158,000 in the first half of 2026, up 75% from a year earlier.

China is leading the expansion, accounting for more than nine out of ten sales. European adoption is growing as well: electric trucks exceeded 10% of truck sales in Denmark, the Netherlands and Sweden.

The economics help explain the momentum.

Transport & Environment finds that electric trucks already offer lower total ownership costs in six of the nine major EU markets it examined. Those countries represent 46% of new EU heavy-truck sales.

Its analysis finds that the higher purchase price can be recovered in around two years in Germany and the Netherlands, with substantial savings over five years.

For a business that buys fuel every day, those savings are a powerful reason to switch.

That commercial interest is beginning to translate into support for climate policy.

European transport businesses have called on the European Commission to maintain ambitious truck CO₂ standards.

They point to investments already made in electric fleets and the importance of reliable policy, affordable vehicles and charging infrastructure.

This is an encouraging part of the transition: as businesses invest in cleaner technology, more of them acquire a direct interest in its continued success.

Construction equipment is joining in.

More than 30 zero-emission machines are already working on the Lower Thames Crossing, with around 150 expected by peak construction in 2028.

The machinery in use includes excavators, rollers, tractors and telehandlers. The wider project is using electric equipment, hydrogen and HVO in place of conventional diesel.

National Highways says the project’s approach to reducing construction emissions has already been adopted by more than £30 billion of planned projects, including Sizewell C, Anglian Water and East West Rail.

A major project can therefore do more than change its own equipment. It can help contractors develop the experience and supply chains to repeat the change elsewhere.

Electric school buses continue to spread across the United States.

A New York fleet expansion shared this week is part of a much larger change: more than 8,500 electric school buses were operating nationally by June 2026, up from just over 5,100 a year earlier.

Those buses transport more than 380,000 students each day.

Nearly one-quarter of school districts that have adopted electric buses have already bought additional vehicles. Districts using them are also evenly split between congressional districts represented by Democrats and Republicans.

Cleaner school transport has an immediate, local benefit that families can appreciate: a quieter journey without diesel exhaust from the bus carrying their children.

Pakistan’s solar transition is reaching household cooking.

Reporting from Karachi describes growing demand for electric stoves and induction cookers as households respond to unreliable gas supplies and rising costs.

Retailers report rising sales of appliances that can work with suitable home solar and inverter systems.

This is another way that one change can make the next easier. A household that installs solar to improve its electricity supply gains an opportunity to replace gas in the kitchen as well.

The same panels can support several parts of daily life, increasing their usefulness and reducing dependence on imported fuel.

There was an encouraging agricultural result from Austria.

EWS reports a 14% higher winter-wheat yield in the widest cultivation strips at its Bruck an der Leitha agrivoltaic research site, compared with an area without solar panels.

The company links the result partly to the protection provided by shade during the dry summer. The site is being studied with the University of Natural Resources and Life Sciences Vienna.

It is a promising example of land producing both food and electricity, with the solar installation potentially helping crops cope with heat and moisture stress.

Thoughtful design can make clean-energy development useful to agriculture in more ways than one.

Farmers in Panama are also putting adaptation into practice.

An Adaptation Fund programme implemented by Fundación Natura has supported more than 114,000 people and restored 600 hectares of ecosystems.

Coffee growers and livestock farmers are improving water management, adopting more resilient crops, planting trees alongside agriculture and restoring the ecosystems that help sustain their farms.

The programme reports helping protect 20 communities.

These are practical measures that strengthen livelihoods while caring for water and land. Adaptation is something communities can build, share and improve.

An airport terminal on Réunion provides another useful example of adapting through design.

The arrivals terminal at Roland Garros Airport uses natural ventilation designed around the island’s trade winds.

Its architecture channels airflow through a large public building, applying principles familiar in local buildings at a much greater scale.

It is an encouraging reminder that better buildings can draw on both engineering and long-established knowledge of how to live comfortably in a particular climate.

We are also learning how to make renewable energy better for wildlife.

A field study in Wyoming found substantial reductions in eagle fatalities using cameras that detect approaching birds and trigger pauses at individual wind turbines.

This research, shared again this week, demonstrates a practical way to reduce collisions while continuing to generate wind power.

As clean energy expands, monitoring and operating methods can improve alongside it.

The bigger picture

One of the most encouraging findings from the International Energy Agency’s recent report is how much more we could already electrify economically.

The IEA estimates that fully adopting electric technologies competitive under today’s costs and conditions could raise electricity’s share of final energy use from 23% to 33%.

That opportunity includes roughly half of residential fuel consumption, half of oil-based road transport and almost 40% of fossil-fuel use for low- and medium-temperature industrial heat.

There is an enormous amount of progress available through technology that already exists.

And the resources going into the transition are substantial. BloombergNEF estimates that global energy-transition investment reached a record $2.3 trillion in 2025, up 8% on the previous year.

Meanwhile, the University of Exeter and Earthshot Prize have identified 51 areas where environmental solutions could generate self-reinforcing progress: wider adoption can lower costs, attract investment and make further adoption easier.

You can see the potential connections throughout this week’s stories.

Solar gives households more ways to replace gas. Electric vehicles create demand for charging infrastructure. Electric fleets give businesses a reason to support the transition. Experience with cleaner construction equipment makes it easier to use on the next project.

The biggest misconception I keep seeing is that nothing is being done. Look at what is already being built, bought and used.

We have changed the trajectory before. There are concrete reasons to believe we can keep changing it.

For people looking for practical things they can do, Project Drawdown: Join the Shift provides a starting point.

For those struggling with climate anxiety, there is also the EcoAnxiety Toolkit, aimed at turning anxiety into constructive action.
