    GLOBAL EMISSIONS FALLING 2025

    With China's emissions falling, global emissions also do.
    2025 was the absolute limit for 2°C as well as 1.5°C from the IPCC 6th Assessment. However, the projected rate of decline is nowhere near 1.5°C and 2°C rates.

    The Paris Climate Accord, while facing political slowdowns in parts of the Global North, remains relevant due to practical momentum elsewhere. As high-income nations delay their net-zero timelines, the production side of the energy transition continues.

    China’s role in that process is increasingly functional rather than diplomatic. The cost reductions driven by its supply chain are allowing for real emissions reductions in places where policy has stalled.

    Renewable adoption is no longer dependent on long-term funding commitments. It is being supported by falling prices and market demand.

    Assessment of the ecological and environmental effects of large-scale photovoltaic development in desert areas | Scientific Reports
    https://www.nature.com/articles/s41598-024-72860-8

    Photovoltaic development has played a crucial role in mitigating the energy crisis and addressing global climate change. However, it has also had significant impacts on the ecological environment. To ensure the sustainable growth of the photovoltaic industry, it is essential to establish an indicator system to assess the ecological and environmental effects of photovoltaic development. This study utilizes the Driving-Pressure–Status–Impact-Response (DPSIR) framework to create an indicator system for evaluating the ecological and environmental effects of desert photovoltaic development. The study evaluates the ecological and environmental effects at the on-site (WPS), transitional zone (TPS), and off-site (OPS) areas of the Qinghai Gonghe Photovoltaic Park in China. The entropy weight method was utilized to calculate indicator weights, while the evaluation model and indicators were transformed uniformly to obtain standardized scores for ecological and environmental effects. and conducting a thorough analysis of the distribution characteristics and factors influencing the evaluation indicators’ scores. Overall, the large-scale development of desert photovoltaics in Gonghe County has had a positive impact on the ecological environment. The WPS had better ecological and environmental conditions than did the TPS and OPS, and the ecological and environmental evaluation levels of the WPS were categorized as “general” (0.439), while the ecological and environmental effect evaluation levels of the TPS (0.286) and OPS (0.28) were both “poor”, indicating significant room for improvement. Moreover, all indicators in the scheme layer, which are used to evaluate ecological and environmental quality, yielded higher scores for the WPS than for the TPS and OPS, demonstrating that photovoltaic development has a positive effect on desert area ecology and the environment.

Absolutní emisní limity budou aplikovány od roku 2027 na vybraná odvětví, a nahradí tak současný systém založený na referenčních hodnotách uhlíkové intenzity. Do roku 2030 by pak měl být systém ETS založený na absolutních cílech snížení emisí plně zaveden v celé zemi a nahradit mozaiku pilotních systémů spuštěných po roce 2021.

    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. ■

    https://jimehansen.substack.com/p/seeing-the-forest-for-the-trees

    Summary: seeing the forest for the trees

    Climate change depends on climate sensitivity and the strength of the forcing that drives change. Of the main sources of information – paleoclimate, modern observations, and GCMs – the first two are least ambiguous, but all three are consistent with climate sensitivity 4.5°C ± 1°C (2σ, 95% confidence) for doubled CO2, which excludes IPCC’s best estimate of climate sensitivity (3°C for doubled CO2). IPCC also underestimates the strength of the aerosol climate forcing.

    In the real world, climate sensitivity and aerosol forcing are independent, but they are joined at the hip in climate assessments that focus on the ability of GCMs to reproduce observed global warming. It is reasonable that climate modelers use observed global temperature change to help constrain the GCMs. The complication is that there are two major unknowns: climate sensitivity (mainly because the cloud feedback is uncertain) and the climate forcing (because the aerosol forcing is unmeasured), while there is only one hard constraint (the observed global warming rate). As a result, if climate sensitivity turns out to be high, greater aerosol forcing (i.e., greater aerosol cooling) is required for agreement with observed global temperature.

    Independent sources of information, from paleoclimate on climate sensitivity and from satellite data on the cloud feedback, show that, in reality, climate sensitivity is high. Thus, aerosol forcing (and the aerosol cooling effect) have also been underestimated by IPCC. In addition, aerosol cooling has weakened since 2005, mainly because of reduced emissions from China and ships.

    Those are the principal conclusions of our two papers (“Global warming in the pipeline” and “Global warming has accelerated”) that address the fundamental issues of climate sensitivity and the human-made climate forcing. These issues are a large part of the “forest” of climate science.

    Within that part of the climate science forest, many uncertainties remain. For example, how does the cloud feedback work? Tselioudis et al.[3] suggest that it is mainly from a poleward shifting of climate zones, as opposed to an effect of global warming on cloud microphysics. It is important to understand such issues, as the correct explanation may affect the continuing climate change.

    Another example: we argue that reduction of ship aerosols has more effect on global temperature than reduction of aerosols from China, even if the mass reduction of Chinese emissions is larger. Ships emissions are more efficient in affecting clouds because they are injected into relatively pristine ocean air at altitudes that have greatest effect on cloud formation. Observed global distributions of albedo and temperature change are consistent with a large role for ship emissions, although alternative explanations for those distributions may be possible. Temporal changes of albedo and temperature also match better with the 2015 and 2020 changes of ship emissions, rather than with the decrease of emissions from China, which began in 2006.

    The forest of climate science includes other areas – besides climate sensitivity and climate forcings – that are also important. For example, potential impacts of climate change include shutdown of the overturning ocean circulation and large sea level rise,[4] which may be the most important of all the climate issues. These climate impacts depend on the magnitude of global warming, which is a reason to first consider climate sensitivity and climate forcings.

    China's CO2 emissions have started falling – is this finally the peak? | New Scientist
    https://www.newscientist.com/article/2480289-chinas-co2-emissions-have-started-falling-is-this-finally-the-peak/

    China, the world’s largest emitter of carbon dioxide, has seen a slight decline in those emissions over the past twelve months, even as demand for power has gone up. This is an encouraging sign the country’s massive buildout of clean energy has begun to displace fossil fuels – but emissions could still surge again.

    That is according to an analysis of China’s economic and energy data by Lauri Myllivirta at the Centre for Research on Energy and Clean Air, a research organisation in Finland. According to the report, published in Carbon Brief, China’s CO2 emissions have declined by 1 per cent over the past 12 months; in the first quarter of 2025 alone emissions declined by 1.6 per cent relative to last year.
    ...
    This isn’t the first time China’s CO2 emissions have dipped. For instance, they dropped in 2022 as the economy came to a standstill during covid-19 lockdowns. But this is the first time emissions have fallen even as the country has used more power. “That, of course, means the current fall in emissions has a much better chance of being sustained,” says Myllivirta.

    This is mainly a consequence of China’s record build-out of solar, wind and nuclear power, which is beginning to eat into the total electricity generated by burning fossil fuels. Wider economic shifts away from cement and steel production, which are carbon-intensive industries, have also contributed to the decline. Another factor is the jump in the share of people driving electric vehicles, which has cut into the demand for oil.

    If China maintains these trends, its carbon emissions could continue to fall. A sustained drop would indicate the country has passed peak emissions, putting it several years ahead of its 2030 target. The achievement would represent a substantial physical and psychological milestone for efforts to tackle climate change, says Myllivirta.
