Biogas and biomethane are often billed as cleaner stand-ins for fossil gas, but a sweeping analysis suggests their methane leaks are bigger than many think. By pooling on-site and whole-site measurements from dozens of studies and running Monte Carlo simulations, researchers find that real-world emissions could be more than double earlier estimates. The heaviest losses cluster at the digestate stage—the handling and storage of leftover material after digestion—while a small group of “super-emitters” (about 5% of sites) accounts for roughly 62% of total methane released. Although total methane from biogas/biomethane is lower than from oil and natural gas, the percentage of gas lost is higher, threatening climate gains unless targeted fixes are deployed.
A summer-long remote-sensing campaign in Paris measured exhaust from more than 180,000 vehicles and uncovered stark gaps between lab promises and street reality. Petrol cars’ NOx fell steadily with each Euro standard, but diesel cars showed little improvement from Euro 2–5 and only modest gains at Euro 6—still averaging 4.8× the NOx of Euro 6 petrol and roughly 6× the lab limit. Heat mattered: Euro 5–6 diesel NOx rose 20–30% when ambient temperatures topped 30°C. Euro 5–6 diesels, though classed as Crit’Air 2, accounted for an estimated 63% of passenger-car NOx at the sites. Euro VI buses cut NOx sharply vs. Euro V, and early Euro 6d-TEMP diesels lowered NOx about 70% vs. earlier Euro 6 but still trailed petrol.
Europe’s forests are absorbing mounting economic damage from climate-driven disasters, and the bill is set to swell. New continent-wide modelling finds historical disturbance losses around €115 billion, rising to €146–€247 billion under future climates depending on emissions, with annual costs climbing from roughly €1.7 to as high as €3.7 billion a year. Central Europe emerges as the hotspot, while Northern Europe often gains more from productivity than it loses to disasters; Southern Europe trends the opposite way. Across the continent, higher tree growth can partly or fully offset disturbance losses, but only reliably under milder warming. The study couples high-resolution growth simulations, more than 150,000 disturbance runs, and economic cash-flow models to translate shocks into euros.
Norway has become the first country where more all-electric cars are on the road than petrol models, a symbolic tipping point in its decades-long push to electrify transport. New figures show 754,303 battery-electric cars versus 753,905 petrol cars among 2.8 million private vehicles, with diesel still the single largest category for now, as first reported by AFP via France 24 Electric cars overtake petrol models in Norway. Momentum is accelerating: in August 2024, zero-emission cars captured a record 94.3% of new registrations, according to Norway’s road federation Bilsalget i august 2024. Analysts credit generous, long-running incentives and a power system dominated by hydropower—roughly 89% of generation—reducing running costs and emissions Norway electricity mix. With policies intact, EVs are expected to surpass diesel on the road within the next few years.
A new analysis extends the classic DICE climate–economy model to directly account for heat-related mortality—and puts a stark number on carbon’s human cost. The study introduces a “mortality cost of carbon” (MCC): in 2020, each additional metric ton of CO₂ is linked to 2.26×10⁻⁴ expected deaths, implying roughly one excess death per 4,434 tons emitted between 2020 and 2100. Incorporating these mortality damages boosts the 2020 social cost of carbon from $37 to $258 per ton and flips the “optimal” policy from slow cuts to full decarbonization by 2050. Under that path, the model projects warming near 2.4 °C and 74 million fewer deaths this century.
Uber Freight has launched a Dedicated EV Fleet Accelerator Program with Tesla to speed up adoption of electric Class 8 trucks. The scheme pairs purchase subsidies with guaranteed freight and route planning, lowering carriers’ risk while giving them operational guidance from Tesla on total cost of ownership. In a two-month pilot across Uber Freight’s network, Tesla Semis ran 12,377 miles with an average 1.72 kWh per mile, reinforcing the economics behind battery-electric long-haul freight, according to Uber Freight. The push aligns with Tesla’s plan to ramp Semi production in Nevada, where the first factory-built units are targeted by late 2025. Earlier pilots real-world runs have already highlighted durability and potential fuel and maintenance savings.
A growing body of research suggests the world passed “peak agricultural land” in the early 2000s, with total farmland slowly shrinking as yields rise and some pastures are abandoned. Efficiency gains and crop substitutions have spared vast areas: higher yields alone may have kept over a billion hectares from cultivation, while synthetic fibres and flavours have eased pressure on land-intensive staples like wool and vanilla. Not all freed acres revert to wild nature—plantation forests often replace them and support less biodiversity. Climate impacts, dietary shifts, and policy choices will determine what happens next. From lab-grown feed and food to greenhouse and vertical farming, technology could accelerate land release—but biofuels, urban growth, or policy rollbacks could reverse the trend according to peak agricultural land research.
Tesla’s Gigafactory Berlin-Brandenburg has been awarded the European Ecolabel (EMAS), recognizing its progress in sustainability. The certification highlights extensive reforestation, reduced water use, solar expansion, and energy efficiency improvements. Officials describe Tesla’s factory as a model for how advanced industry and ambitious climate goals can work hand in hand.
A Nature Climate Change study links tropical deforestation to about 28,000 additional heat-related deaths annually (95% CI: 23,610–33,560). From 2001–2020, 345 million people were exposed to deforestation-driven warming; affected areas saw 0.27°C average daytime warming, with 0.45°C directly attributable to forest loss. Mortality is highest in Southeast Asia, then Africa, then the Americas.
