<p class="has-text-align-center"><em>Welcome to Carbon Brief’s DeBriefed. </em><br /><em>An essential guide to the week’s key developments relating to climate change.</em></p>

<h3 class="wp-block-heading"><strong>Renewables overtake coal</strong></h3>

<p><strong>‘HISTORIC FIRST’: </strong>Renewables have overtaken coal to become the world’s leading source of electricity for the first six months of this year in a “historic first”, <a href="https://www.bbc.co.uk/news/articles/cx2rz08en2po">BBC News</a> said. The analysis, from the thinktank Ember, found the world generated “almost a third” more solar power in the first half of the year, compared with the same period in 2024, while wind power grew by “just over 7%,” reported the <a href="https://www.theguardian.com/environment/2025/oct/07/global-renewable-energy-generation-surpasses-coal-first-time">Guardian</a>.</p>

<p><strong>HEAVY LIFTING: </strong>According to the report, China and India were “largely responsible for the surge in renewables”, while the US and Europe “relied more heavily on fossil fuels,” the Guardian wrote. China built more renewables than every other country combined in the first half of this year, the newspaper added.</p>

<p><strong>CONTINENTAL SHIFTS:</strong> A second report from the International Energy Agency (IEA) predicted a “surge” in global wind and solar capacity by 2030, but shaved 5% off its previous forecast, the <a href="https://www.ft.com/content/2fa6f6cb-3b7f-4fa7-85c1-a8b107a55259">Financial Times</a> said. The IEA revealed that India is set to become the second-largest growth market for renewables after China, “with capacity expected to increase 2.5 times by 2030”, <a href="https://www.downtoearth.org.in/energy/india-to-become-second-largest-renewable-market-as-global-growth-doubles-iea">Down to Earth</a> reported. The IEA also upped its forecast for renewables in the Middle East and north Africa by 23%, “helped by Saudi Arabia rolling out wind turbines and solar panels”, but halved the outlook for the US, the FT noted. </p>

<h1 class="wp-block-heading"><strong>Captured</strong></h1>

<p>The UK’s Climate Change Act, landmark legislation that guides the nation’s response to climate change, is increasingly coming <a href="https://www.carbonbrief.org/debriefed-3-october-2025-uk-political-gap-on-climate-widens-fossil-fuelled-typhoon-ragasa-overshoot-unknowns/">under attack</a> from anti-net-zero right-leaning politicians. In a factcheck published this week, <a href="https://www.carbonbrief.org/factcheck-what-the-climate-change-act-does-and-does-not-mean-for-the-uk/">Carbon Brief</a> explained how the UK’s Climate Change Act was among the first comprehensive national climate laws in the world and the first to include legally binding emissions targets. In total, 69 countries have now passed “framework” climate laws similar to the UK’s Climate Change Act, with laws in New Zealand, Canada and Nigeria among those explicitly based on the UK model. This is up from just four when the act was legislated in 2008. Of these, 14 are explicitly titled the “Climate Change Act”.</p>

<h1 class="wp-block-heading"><strong>Spotlight</strong></h1>

<h3 class="wp-block-heading"><strong><strong>Fukushima’s solar future</strong></strong></h3>

<p><em>This week, Carbon Brief examines how Fukushima helped to recover from nuclear disaster by building solar farms on contaminated farmland.</em></p>

<p>On 11 March 2011, an earthquake off the pacific coast of Japan caused 15m-tall waves to crash into the eastern region of <a href="https://en.wikipedia.org/wiki/2011_T%C5%8Dhoku_earthquake_and_tsunami">Tōhoku</a>, killing 19,500 people and injuring a further 6,000.</p>

<p>In the aftermath, flooding at the Fukushima Daichi nuclear power plant caused cooling systems to fail, leaching radioactive contaminants into the soil and leading to a <a href="https://www.carbonbrief.org/analysis-the-legacy-of-the-fukushima-nuclear-disaster/">major nuclear incident</a>. </p>

<p>Some 1,200km2 around the site was <a href="https://www.britannica.com/story/nuclear-exclusion-zones">restricted</a> and up to <a href="https://world-nuclear.org/information-library/safety-and-security/safety-of-plants/fukushima-daiichi-accident">100,000 people</a> were evacuated – in some cases forever.</p>

<p>In the years following, Japan entered a <a href="https://www.japantimes.co.jp/news/2025/07/15/japan/politics/energy-security-election/">fraught</a> <a href="https://www.japantimes.co.jp/news/2025/03/12/japan/ishiba-nuclear-policy/">debate</a> about nuclear energy.</p>

<p>In 2010, nuclear power provided <a href="https://www.energyinst.org/statistical-review/resources-and-data-downloads">25%</a> of Japan’s electricity, but, in the years following the disaster, its <a href="https://www.eia.gov/todayinenergy/detail.php?id=64204">54 nuclear reactors</a> were taken offline.</p>

<p>Successive governments have fought over reintroducing nuclear power. Today, some <a href="https://world-nuclear.org/information-library/country-profiles/countries-g-n/japan-nuclear-power#:~:text=The%20first%20two%20reactors%20to,but%20this%20was%20not%20achieved.">14</a> reactors are back online, <a href="https://pris.iaea.org/pris/CountryStatistics/CountryDetails.aspx?current=JP">27</a> have been permanently closed and another <a href="https://pris.iaea.org/pris/CountryStatistics/CountryDetails.aspx?current=JP">19</a> remain suspended. (Japan’s newly-elected prime minister <a href="https://www.japantimes.co.jp/news/2025/10/06/japan/politics/takaichi-focus-on-nuclear-energy/">Sanae Takaichi</a> has promised to make nuclear central to her energy strategy.)</p>

<p>Against this backdrop, Fukushima – a prefecture home to <a href="https://www.eu-japan.eu/eubusinessinjapan/fukushima-prefecture">1.8 million people</a> – has emerged as a surprise leader in the renewables race. </p>

<p>In 2014, the <a href="https://www.aist.go.jp/fukushima/en/">Fukushima Renewable Energy Institute</a> (FREA) opened with the twin goals of promoting research and development into renewable energy, while “making a contribution to industrial clusters and reconstruction”.</p>

<p>That same year, the prefecture <a href="https://www.climatechangenews.com/2014/01/31/fukushima-to-use-100-renewable-energy-by-2040/">declared</a> a target of 100% renewable power by 2040. </p>

<h3 class="wp-block-heading">Contaminated land</h3>

<p>“A lot of these communities, I know, were looking for ways to revitalise their economy,” said <a href="https://science.gmu.edu/directory/jennifer-sklarew">Dr Jennifer Sklarew</a>, assistant professor of energy and sustainability at George Mason University and author of “<a href="https://www.routledge.com/Building-Resilient-Energy-Systems-Lessons-from-Japan/Sklarew/p/book/9781032130835?srsltid=AfmBOooE66SbcBIU2ALvsOhCzir5ThshgNxe5iLT4aJf3uvHZUf9cQif">Building Resilient Energy Systems: Lessons from Japan</a>”.</p>

<p>Once evacuation orders were lifted, however, residents in many parts of Fukushima were faced with a dilemma, explained Sklarew: </p>

<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p>“Since that area was largely agricultural, and the agriculture was facing challenges due to stigma, and also due to the soil being removed [as part of the decontamination efforts], they had to find something else.”</p>
</blockquote>

<p>One solution came in the form of rent, paid to farmers by companies, to use their land as solar farms.</p>

<p><a href="https://ieefa.org/people/michiyo-miyamoto">Michiyo Miyamoto</a>, energy finance specialist at the <a href="https://ieefa.org/">Institute for Energy Economics and Financial Analysis</a>, told Carbon Brief:</p>

<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p>“The [Fukushima] prefecture mapped suitable sites early and conducted systematic consultations with residents and agricultural groups before projects were proposed. This upfront process reduced land-use conflicts, shortened permitting timelines and gave developers clarity.” </p>
</blockquote>

<p>As a result, large-scale solar capacity in Fukushima increased to more than 1,300 megawatts (MW) from 2012 to 2023, according to Miyamoto. Moreover, installed renewable capacity now exceeds local demand, meaning the region can run entirely on clean power when conditions are favourable, Miyamoto said.</p>

<p>Today, aerial pictures of Fukushima reveal how solar panels have proliferated on farmland that was contaminated in the nuclear disaster. </p>

<h3 class="wp-block-heading">Charging on</h3>

<p>Last year, <a href="https://www.fukushima-tv.co.jp/localnews/2025/09/2025091900000008.html">60%</a> of Fukushima’s electricity was met by renewables, up from <a href="https://www.tokyofoundation.org/research/detail.php?id=806#:~:text=In%20the%20wake%20of%20the,zero%20carbon%20emissions%20by%202050?">22%</a> in 2011. (The country as a whole still lags behind at <a href="https://www.isep.or.jp/en/1561/">27%</a>.)</p>

<p>And that is set to grow after Japan’s largest onshore windfarm started operations earlier this year in <a href="https://www.sumitomocorp.com/en/jp/news/release/2025/group/19910">Abukuma</a>, Fukushima, with a capacity of 147MW.</p>

<p>The growth of solar and wind means that Fukushima is already “ahead of schedule” for its 2040 target of 100% renewable power, said Miyamoto:</p>

<blockquote class="wp-block-quote is-layout-flow wp-block-quote-is-layout-flow">
<p>“The result is a credible pathway from recovery to leadership, with policy, infrastructure and targets working in concert.”</p>
</blockquote>
