    The green transition has a surprising new home

    Forget about northern Europeans, with their coalition governments and love of cycling

    Picture a country where renewables are being rapidly rolled out and electric-vehicle sales are surging, and you will probably have in mind somewhere smug and northern European; a place with tall people, coalition governments and a yen for cycling holidays. Or perhaps the first thing that pops into your head is the sheer scale of China, which manufactures the bulk of such equipment and last year contributed more than half of the global increase in solar and wind installation.Think again. For a wave of Chinese-made electric vehicles is flooding new markets. In the past year sales of evs have more than tripled in Turkey, where Togg, a local brand, is also popular—they now account for 27% of all cars sold, making the country the fourth-largest European market. Last year more than 70% of cars imported into Nepal were electric. Some 60% of new cars sold in Ethiopia were battery-powered, after the state banned sales of internal-combustion-engine vehicles altogether. ev sales have doubled in Vietnam over the past year owing, in part, to VinFast, a local carmaker. Two- and three-wheelers are surging in popularity, too. The International Energy Agency (iea), a forecaster, reckons that across developing countries in Africa, Asia and Latin America ev sales rose by 60% in 2024.

    It is a similar story with renewables. In the first six months of the year, Pakistan generated 25% of its electricity from solar power—not far below the 32% managed by California, a clean-energy pioneer. The country’s battery imports are booming as well. Indeed, the Institute for Energy Economics and Financial Analysis, a think-tank, estimates that on current trends battery storage will cover 26% of Pakistan’s peak-electricity demand by 2030. Meanwhile, over the past year Morocco has increased its wind generation by 50%, becoming the country with the ninth most. India has seen four months of decline in coal-power generation, aided by an increase of 14% in renewable generation.Lust for powerAlthough the principles of international climate diplomacy suggest that poorer countries, being less responsible for climate change, have less duty to go green, many face strong economic incentives to do so anyway. Most countries in the global south are energy importers, and therefore must use scarce foreign currency to buy oil and gas. China and India have coal reserves that play an important role in their economies and power generation, but neither has significant oil or gas reserves. For its part, Ethiopia’s ban on internal-combustion engines was not a green measure—it was designed to cut spending on fossil fuels and save foreign currency.

    Moreover, across emerging markets, Chinese-made evs are now about as cheap as traditional vehicles. In some places, they are even cheaper. The iea reckons that last year the average Chinese ev sold for around $30,000 in Thailand, compared with $34,000 for the typical petrol-engine car. At the bottom end of the market, old-fashioned vehicles still have an advantage, but only a relatively modest one. Government policies have also made a difference. In Turkey purchasers of evs typically paid a tax of only 10%, compared with one of between 45% and 220% for petrol-powered vehicles. The recent surge in part reflected car-buyers getting ahead of a reduction in the generosity of the policy.

    Clean technology generally requires more upfront investment than fossil-fuel tech, even if it has lower lifetime costs. This has historically held it back in places where the cost of capital is high. The iea has calculated that the typical cost of capital for a solar project in India, for instance, is 11%, compared with around half that in rich countries. But the Rocky Mountain Institute, an American pressure group, now estimates that, owing to falling prices, many clean technologies have reached “capex parity”, where initial costs are the same as fossil fuels on a per-unit basis. As a consequence, they have become more attractive in large parts of the world.Tariffs have been helpful, too. As America and the eu attempt to shut out Chinese evs, they are finding their way to other markets—at even cheaper prices. For the most part, emerging markets lack legacy manufacturers that will lobby their governments to keep out Chinese imports. Yet this relatively free trade is at risk as protectionism begins to spread. Until recently Brazil allowed evs into its economy tariff-free; now it is gradually raising import taxes to 35% by 2026. India’s imports of finished solar panels have stagnated as the country seeks to build its own supply chain. Nigeria is considering banning solar-panel imports altogether in an effort to support domestic manufacturers.

    Governments are at least also creating loopholes that allow Chinese imports to continue so long as the companies in question commit to local production. Brazil has carved out an exemption for byd, a carmaker, while it establishes a factory in the country. Indonesia has reduced value-added tax on evs from 11% to 1% for vehicles that meet a 40% local-content requirement; foreign manufacturers, meanwhile, can bring in equipment duty-free so long as they promise to increase domestic production by 2026 and provide a guarantee for the forgone tariffs if they do not follow through. Such policies are far from perfect—but they are better than the alternative. Well-heeled northern Europeans have something to learn. ■

    XCHAOS: Požáry letos v zemích Evropské unie spálily už přes milion hektarů, což je nejvíce od začátku sledování této statistiky v roce 2006. S odvoláním na data z unijního systému EFFIS to ve čtvrtek uvedla agentura AFP, podle níž jde o území větší než Korsika. Odpovídá také třeba ploše Jihočeského kraje. Nejpostiženější jsou Španělsko a Portugalsko, kde plameny dohromady zničily více než 677 000 hektarů.

    Požáry ve Španělsku jsou tak ohromné, že množství emisí, které se do ovzduší dostaly za sedm až osm dní v srpnu, překonalo celkové roční emise z lesních požárů v posledních 23 letech

    Za den shořela stejná plocha jako za celý loňský rok. Španělsko a Portugalsko sužují extrémní požáry • RESPEKT

    Jižní Evropa zažívá jednu z nejhorších sezon lesních požárů za poslední dvě dekády. Například Pyrenejský poloostrov ohně sužují už dva týdny. V případě Španělska jde hlavně o severozápad země, kdy ještě v úterý navečer hasiči evidovali na 40 ohnisek.

    Situaci řeší i centrální vláda v Madridu, která plánuje na zasažených místech vyhlásit stav mimořádné události civilní ochrany a v příštím měsíci předložit plán boje proti klimatickým změnám. „Zemřelo i několik lidí. Za 24 hodin tam shořela stejná plocha jako za celý loňský rok.

    Z dat EFFIS vyplývá, že jen ve Španělsku, napříč několika regiony, spálil oheň plochu čítající 400 tisíc hektarů. Jak píše agentura Reuters, to je jako by shořela celá Mallorca," říká ve Výtahu Respektu Štěpán Sedláček, který dodává, že extrémní požáry jsou také v Portugalsku. Jaká je tam situace? Jak se s požáry doposud vypořádávalo sousední Španělsko a jaký by mohl být budoucí plán boje s klimatickou změnou?

    A jak vlastně klimatologové hodnotí letošní léto v Česku?

    One of the most severe marine heatwaves on the planet is taking place in the shallow seas around the UK and Ireland. That’s according to the US National Oceanic and Atmospheric Administration (NOAA), which has labelled this a “Category 4” heatwave. Rarely used outside of the tropics, a cat 4 heatwave means “extreme” heat.

    Marine heatwaves are classified as “prolonged periods of anomalously high sea surface temperature”, when compared to the long-term average for that time of year. And thanks to measurements made by satellites orbiting the earth we know that, in some areas around the UK, surface water temperatures are 4°C to 5°C above normal for mid June.

    This is extremely unusual: buoys around Ireland and the UK have been recording sea surface temperature for over 20 years, and in that time it has never been this hot this early in the summer.
    ...
    At this time of year, these plankton are dependent on nutrients mixed up from the deep water into the surface layer. However, this year, this nutrient supply may be diminished, since the very high surface temperature means there is likely stronger stratification and less mixing.

    A heatwave on the surface could potentially harm the deeper ocean too, and the fish that live there. These continental shelf seas are already suffering from a decline in deep water oxygen, which is partly offset by mixing oxygen-rich water from the surface. However, the fact that the surface temperatures are so high point to a lack of mixing between the layers, and in any case, warmer water contains less oxygen.

    An ‘extreme’ heatwave has hit the seas around the UK and Ireland – here’s what’s going on
