London’s 88,000 new homes a year target at risk as building costs soar

Soaring construction costs are exacerbating London’s housing crisis, according to independent think tank Centre for London (CfL). London’s housing crisis continues to escalate. The government wants to see 88,000 new homes built in the capital every year until 2030, but CfL’s analysis reveals that this will become increasingly challenging. It has revealed that the upfront cost to developers of constructing these new homes will be at least £2.2bn. That is roughly 43 times higher than the equivalent target in the West Midlands (£50.6m), and 36 times higher than in Greater Manchester (£61.3m). This estimate was reached by combining the costs associated with the Building Safety Levy, section 106 agreements, the Community Infrastructure Levy and planning fees for local councils. It also…

Satellite chase reveals environmental impact of space sector

European researchers pursued a satellite falling from the sky to learn how its burn-up affects Earth’s atmosphere. Their findings will help the space industry understand the harm it is doing to the environment and, hopefully, reduce its impacts. It was shortly after noon local time on 8 September 2024 when a streak of smoke, burning as brightly as the midday moon, visible at the same time, appeared on the blue sky above the dark waters of the Pacific Ocean. Flying towards that fireball was a Falcon business jet carrying 12 researchers working under the banner of the European Space Agency (ESA). None were able to observe the daytime fireball as the windows of the aeroplane, which had taken off from Easter Island about three hours earlier, were covered with black fabric. After that fleeting…

Millions of birds are dying on power lines – can we stop it?

Millions of birds are dying every year – what can we do to protect them from the growing electrical network? It is a painful clip to watch – an elegant swan in flight collides with the highest wire strung above power cables and sinks to earth in a tangle of bent and broken feathers. In another incident caught on video, a startled white-tailed eagle crashes into overhead cables and drops like a stone after a sudden flash. Singed feathers and tell-tale burns can reveal how a bird died, but if these incidents had not been filmed they might have passed unremarked. In the UK and across most of the world, no one is required to count the millions of birds that crash into or are electrocuted by live overhead wires spanning the countryside. Eagles, storks, bustards, vultures and other endangered…

£250 energy bill discount fails to win over locals opposed to nearby energy infrastructure

While a majority of Brits recognise the UK’s current energy infrastructure is unfit for the future, many remain firmly opposed to having new wind farms, solar panels or pylons built near their homes – despite offers to lower their energy bills. In September 2024, Labour set out ambitious planning reforms that aim to streamline the process for approving critical infrastructure and overhaul rules on the compulsory purchase of land. The UK currently faces an urgent need to revamp the electricity grid and accelerate new infrastructure to support the increase in renewable energy projects. But to prevent backlash from local residents, the government has proposed slashing £250 a year off their energy bills. Nevertheless, a survey from KPMG and YouGov found that one in three (32%) respondents…

Countdown to 2030: EV goals loom as charging infrastructure lags behind

The UK automotive industry now has until 2030 to reach government zero-carbon targets. Ministers bring forward the ban on the sale of new petrol and diesel vehicles by five years; government investment for electric vehicle (EV) charging infrastructure and batteries announced in budget; huge increases in required battery capacity predicted by 2040. The UK automotive industry’s race towards a zero-carbon 2030 is underway. But with numbers of people driving EVs still below the required amount, what’s needed, now and next, if the UK is to meet its zero-carbon targets? Government waved the chequered flag on 17 September last year, when ministers scrapped the previous 2030 deadline for banning the sale of new vehicles powered solely by petrol and diesel and announced £88m funding for new zero…

Editor's comment: Electrification powers the nation

The transition to electricity has added impetus towards a net zero approach. Historically one of the big criticisms of plans to reduce greenhouse gases was that the road map to get there was sufficiently vague and non-committal that actual action was always a can that could be kicked down the road. And while recent COPs have again replaced specifics with aspiration, the majority of the world is making steps in the right direction. In the UK, the trend for overall energy consumption has been downward for nearly a quarter of a century, while despite the gradual switch to electricity, it too decreases year on year (typically by 1-2%). However, transport remains an outlier, gathering pace and still using an increasing amount of fossil fuels. The switch to EVs, as discussed in the article on p32…

Major UK supermarket deploys shelf-scanning robots to roam the aisles

Morrisons has begun trialling robots in select stores that roam the aisles to monitor how products are being displayed on shelves. The Tally robots, developed by California-based company Simbe, have been deployed at three stores – in Wetherby, Redcar and Stockton. Tally is able to automate the tedium of scanning store shelves to conduct product audits. The roughly 1.5m tall robot traverses store aisles to carry out inventories of the shelves and floor displays, delivering real-time data about mispriced products and stock shortages. The platform integrates multiple advanced sensing technologies – including computer vision cameras, RFID readers and precision depth sensors – to create a complete digital twin of the retail environment. As Tally traverses store aisles, this multi-sensor array…

Grassroots energy projects offer glimmers of hope in slow net zero transition

The UK energy infrastructure is pulling on local resources to balance demand – progress is slow, but it is happening. On the side streets of Bacup, Lancashire, UK, in two-up two-downs nestled around a former mill, work began in January to convert the first properties as part of a new project. It could be indicative of methods to bring low-cost green heating to millions of homes that otherwise seem to be locked out of the planned transition to net zero. Rossendale Valley Energy’s Net Zero Terrace Streets (NZTS) project is an attempt to find a way to fit often bulky heat pumps in homes with little free space. A householder in a more suburban setting is more likely to be able to live the net zero ‘Good Life’, in an echo of the suburban self-sufficiency enthusiasts at the centre of the sitcom…

Trump’s ‘war on clean energy’ is putting 400,000 jobs at risk

President Donald Trump’s cuts to the US clean energy industry have led to significant job losses and threatened almost $70bn in project investments, according to a Climate Power report. On Donald Trump’s election campaign trail last year, he pledged to boost oil and gas production in the US with a promise to “drill, baby, drill”. Indeed, his day one executive orders honoured this promise. Just hours after taking office, Trump pulled the US out of the Paris Agreement. He also announced a “national energy emergency” that allowed him to swiftly reverse many Biden-era regulations that aimed to curtail the oil and gas sector, including shutting down construction on the Keystone Pipeline. In April, he also signed a series of executive orders designed to reinvigorate the US coal industry. At…

UK government expands Boiler Upgrade Scheme to boost access to low-carbon heating tech

The Department for Energy Security and Net Zero (DESNZ) has launched a consultation to expand the range of low-carbon technologies homeowners can claim under the Boiler Upgrade Scheme (BUS). Heat pumps are seen by the government as a vital tool in cutting the carbon emissions from people heating their homes. To enable more people to benefit from this as well as other low-carbon technologies and to enable the switch from fossil fuel-based heating systems, BUS was introduced in April 2022. In 2023, the government’s £450m BUS was recently extended until 2028, offering grants of £7,500 towards the cost of a new heat pump. Home heating accounts for 18% of UK greenhouse gas emissions, despite the government having introduced the BUS Nesta report last year showing that uptake of low-carbon…

UK government failing to prepare for extreme weather, climate watchdog warns

The government’s climate advisers warn that progress on climate change is “either too slow, has stalled, or is heading in the wrong direction”. The past year has seen our environment ravaged by extreme weather conditions, from flooding and droughts to wildfires and hurricanes. Scientists argue that these extreme weather events are made even more likely as the result of human-driven climate change. Speaking at the COP29 climate conference at the end of last year, Prime Minister Keir Starmer said his government “recognises that the world stands at a critical juncture in the climate crisis” and that the UK “has a critical role to play”. However, a new report from the UK government’s climate watchdog, the Climate Change Committee (CCC), reveals that the government is not appropriately prepared…

Which transmission tech is best for the UK’s great grid upgrade? IET report finds out

As the UK pushes to fully decarbonise its energy grid by 2030, a new report compares the costs and characteristics of overground, underground and subsea power transmission. The UK government has set itself the lofty goal of entirely decarbonising the UK’s energy grid by 2030. However, this requires the country’s electricity infrastructure to be significantly expanded and upgraded. A report last year suggested that the grid was not ready for the major influx of green energy coming online in the next few years. BloombergNEF data suggested that for every pound invested in renewable energy, the UK should be investing at least £1 in the grid, but the current ratio is more like 25p to every £1. National Grid’s Electricity System Operator estimates that Britain’s electricity needs will rise…

Spain blackout underscores urgent need for investment in ‘vulnerable’ UK grid

The nationwide blackout of Spain’s electricity network highlights the vulnerability of grids on peninsulas and islands such as the UK, an energy expert has said. Yesterday, a major incident saw millions of households and businesses across Spain, Portgual and southern France lose power in what was the largest power cut in Europe’s recent history. While power has now been restored to more than 99% of affected areas, the cause of the blackout has not yet been identified. Various explanations have been offered, including cyber attacks on the grid and atmospheric phenomena across Spain. Portuguese grid operator REN said “extreme variations” in Spain’s temperature caused the power failure, though Spanish transmission system operator Red Eléctrica has so far given no reason for the outage. …

Nuclear energy ramps up in China as 10 new reactors approved

China’s State Council has approved the construction of 10 new nuclear reactors, as reported by Bloomberg. While it was recently revealed that the world’s largest energy consumer plans to keep building coal-fired power plants through to 2027, it is also ramping up its renewables development. In July 2024, the Global Energy Monitor found that China was building almost twice as much wind and solar energy capacity as every other country in the world combined, with 180GW of utility-scale solar and 159GW of wind power already under construction. Bloomberg has now reported that China is also ramping up nuclear power with the approval of at least 10 new nuclear reactors, the fourth consecutive year that number has been endorsed. With 30 nuclear reactors currently under construction, nearly…

British scientists given £50m to explore sun-dimming techniques to fight climate change

The government is giving a team of British scientists £50m to research techniques to dim the sun in order to tackle the worst consequences of climate change. Geoengineering methods have been proposed that aim to reduce or counteract global warming by reflecting sunlight away from the Earth through techniques including stratospheric aerosol injection and cloud brightening. Global temperatures in the first quarter of 2025 were the second warmest on record, extending a run of exceptional warmth that began in July 2023. Now a team at the University of Cambridge are looking at whether geoengineering techniques could reverse this process – and whether they would be safe to deploy on a large scale. A series of outdoor experiments are set to take place with £56.8m in funding from the government…

Emissions from European airlines soar to pre-Covid levels, study finds

European airline emissions are almost back to where they were in 2019, and flights within Europe are already exceeding pre-pandemic levels, a new study finds. Environmental group Transport & Environment (T&E) found that in 2024 the European aviation sector had almost fully bounced back to pre-Covid levels, reaching 96% of 2019 flight numbers and 98% of emissions. Over 8.4 million flights departed from European airports, generating 187.6 million metric tons of carbon dioxide (Mt CO₂). T&E’s study showed that 10 airlines were responsible for 40% of all European aviation emissions, with the top polluters being Ryanair (16 Mt CO₂), Lufthansa (10 Mt CO₂) and British Airways (9 Mt CO₂). Krisztina Hencz, aviation policy manager at T&E, said: “Aviation emissions are spiralling out of control…

Gatwick agrees to tighter noise limits in bid to secure approval for second runway

Gatwick Airport has said it will accept terms proposed by the government to implement local noise restrictions if it is granted consent to operate its additional runway. Transport minister Heidi Alexander said earlier this year that she would likely approve the expansion but is not expected to make the final decision until October. The airport currently has a northern runway that runs parallel to the main one, but they cannot be used at the same time as they are too close together. Gatwick wants to shift the runway 12 metres further away to allow both to operate simultaneously. The move should open up Britain’s skies to an additional 100,000 flights per year while creating an estimated 14,000 jobs. In its latest response, Gatwick said it would accept stricter limits on aircraft noise…

UK faces 5bn-litre daily water shortfall by 2050 without urgent infrastructure investment

The UK faces a daily shortfall of 5 billion litres of fresh water by 2050 due to poor quality infrastructure, the National Audit Office (NAO) has said. In a report, the public spending watchdog found that the government and regulators have failed to drive sufficient investment in the water sector, which now needs to build 30 new projects at a cost of £52bn to meet future water demand. In England and Wales, 16 companies manage water supply – with 11 also handling wastewater services – that fall under regulatory oversight to protect public and environmental interests. But while the UK has one of the highest standards of drinking water in the world, performance has not improved for almost a decade in key measures, including mains bursts, supply interruptions and pollution incidents, the…

British satellite to map Earth’s forests in 3D and reveal carbon secrets from space

A British satellite that will map the world’s forests in 3D to keep track of climate change will be launched into space next week. Tree coverage plays an important role in tracking climate change, with deforestation activities releasing stored carbon dioxide into the atmosphere while fresh forest growth captures atmospheric CO2. Data from the Mauna Loa Observatory in Hawaii recently showed that atmospheric CO2 levels surged faster than expected in 2024 because of deforestation activities and a series of unprecedented wildfires. The satellite, called Biomass, will create a 3D map of tropical forests after 17 months, then new (non-3D) maps every nine months for the rest of its five-year mission. It is hoped the data will provide unique insights normally hidden from human sight because of…
