COP27 saw two major outcomes on the finance front: the creation of a “Loss and Damage” fund and a call to reform international financial institutions. It made fewer, if any, advances to reduce emissions, and narrowly missed sending a global call to phase down oil and gas consumption. But funding the emissions reductions of developing and vulnerable nations was a gap that had to be filled, and so this is a big step forward, explains Lola Vallejo … [Read more...]
Solar PV windows on highly glazed skyscrapers can cut energy by 40%+
Around a third of the world’s energy consumption and CO2 emissions come from buildings. Highly glazed skyscrapers and buildings may look beautiful and let in plenty of light, but waste a lot of energy due to the extra cooling needed in summer and heating in winter. Modern skyscrapers can have window-to-wall ratios of 70%+. But modern thermally efficient photovoltaic windows not only provide insulation but turn the absorbed light into power. Wayne … [Read more...]
What does the “global carbon budget” mean? Have we got 9 years left?
Piers Forster and Debbie Rosen at the University of Leeds and Robin Lamboll and Joeri Rogelj at Imperial College London, writing for Carbon Brief, look at the carbon budget estimates of the Global Carbon Project and the IPCC, the methodology and the inevitable uncertainties. They compare it to their own latest report from the CONSTRAIN research project. Where the GCP and the IPCC estimate nine years left of carbon emissions at current emission … [Read more...]
IEA says peak coal is a few years away, but China’s demand for energy suggests not
Lucas Davis at the Haas School of Business questions the IEA’s optimism revealed in its latest World Energy Outlook 2022 that predicted coal will peak in the next few years. In 2021, global coal consumption increased 5% and global electricity generation from coal reached an all-time high. China is the main driver - last year over half of all coal-fired electricity generation came from China - and its energy demand keeps rising. Between 2000 and … [Read more...]
Corporate greenwashing: will court cases and new rules close the gap between promises and reality?
Activists are taking firms to court over deceiving consumers with questionable climate pledges. Isabel Sutton at Clean Energy Wire summarises the issues. Greenwashing, and therefore misdirecting consumer behaviour, is clearly a barrier to achieving climate goals. The latest IPCC report says consumer behaviour and changes to our lifestyles can result in a 40%–70% reduction in greenhouse gas emissions by 2050. But unregulated advertising can say … [Read more...]
How European nations are using tax to promote zero-emissions cars
Taxation is an effective way to steer people towards zero-emission cars. But there is wide variation between European countries in how this is done, and therefore the results. Griffin Carpenter at Transport & Environment (T&E) summarises their report “The good tax guide: A comparison of car taxation in Europe” that covers seven forms of car taxation across 31 European countries in detail. The ultimate goal should be to create a clear … [Read more...]
Investing in Hydrogen: is there a “first mover advantage”?
Is there a “first mover advantage” – or not - for an investor in the new hydrogen economy? Michiel Korthals Altes offers a series of “tests” of investment decisions based on the following criteria: economics, climate efficiency, system optimum, price stability, regulation, technology, now and in the future. He concludes that until the sector reaches maturity, conversion inefficiencies make the production of hydrogen a poor choice for most … [Read more...]
EVs are on track for net-zero emissions
The IEA says “Electric Vehicles” is one category that is on track to meet their Net Zero Emissions by 2050 Scenario. Road transport accounts for 16% of global emissions. Recent years have seen exponential growth in the sale of EVs, together with improved range, wider model availability and increased performance. The IEA estimates that 13% of new cars sold in 2022 will be electric. Most of the progress is taking place in established markets – i.e. … [Read more...]
Aviation emissions: don’t wait for CORSIA. Strengthen EU ETS and Fit-for-55
The European Aviation Safety Agency (EASA) has projected growth in flights of 40% between 2018 and 2035. So how do we reduce aviation emissions? The global implementation of the Carbon Offsetting and Reduction Scheme for International Aviation (CORSIA) remains low. Meanwhile, Europe’s EU ETS has helped reduce the sector’s emissions by around 17m tonnes of CO2eq per year - but it did not bring a net decrease in emissions. Technological progress … [Read more...]
Hydrogen imports: strict rules can deliver a win-win for Europe and developing nations
### Today’s article flags up a fascinating panel discussion on the book “Touching Hydrogen Future”, as part of the European Hydrogen Week taking place from 24-28 October 2022. This webinar, on Oct 28 at 10:00 CEST, will be blue-sky thinking about the future of the hydrogen economy. Global in scope, it will dive into how a hydrogen-powered future might look in the Netherlands, Greece, Ukraine and Morocco. REGISTER HERE ### The EU is moving … [Read more...]
New U.S. study: damage per ton of CO2 costs $185, not the official $51
Maximilian Auffhammer at the Energy Institute at Haas reviews a new paper that suggests CO2 causes over three times as much damage in dollar terms as the figure currently used by the US government, $51 per ton. The new study shows $185 per ton of CO2 as the Social Cost of Carbon (SCC). The updated model is superior to previous models, says Auffhammer. It’s also open source, so anyone can use it, criticise it, and tweak the numbers to get … [Read more...]
How to turn a 17-minute private jet flight into investment for green aviation
Flights in private jets are 10 times more polluting than commercial flights, according to T&E. It’s why, this summer, public anger grew over their use by celebrities and rich individuals, following the attention drawn to them by the Twitter account @CelebJets that tracks their use. Kylian Mbappe, Taylor Swift, Kylie Jenner, Elon Musk and many more: sports stars, pop stars, rich entrepreneurs, they were all named along with the very short … [Read more...]
Electrochemical CO2 removal: efficient, cheaper, first industrial client
Leda Zimmerman at MIT describes a method of removing CO2 electrochemically, now being taken forward by MIT spin-off company Verdox. Electrodes are coated with polyanthraquinone. When it is charged, CO2 sticks to it. When it’s time to store it away, the charge is reversed and the gas is expelled as a pure stream of CO2. The technology works in a wide range of CO2 concentrations, from the 20% or higher found in cement and steel industry exhaust … [Read more...]
China: decades of support for innovation is now delivering results
The evolution of China’s clean energy sector used to be based on a technology catch-up approach, which meant secondary innovation based on imported technologies. Daisy Chi at ECECP looks at the IEA’s recent report, “Tracking Clean Energy Innovation: Focus on China”, to conclude that the nation is now a major force in clean energy innovation. Decades of innovation-focussed policies, strong funding support, institutional reforms, big targets and … [Read more...]
Copenhagen will miss its 2025 net-zero target: a case study of how pledges fail
Copenhagen is going to miss its 2025 net-zero target. The reason can be taken as a template for why we may soon see other failing pledges from governments and corporates. Kirstine Lund Christiansen at the University of Copenhagen and Inge-Merete Hougaard at Lund University explain that Copenhagen’s emissions overspill stems from an unrealistic dependence on technology when the promise was first made in 2012. As the target date got closer, other … [Read more...]
