Cement production accounts for 8% of global emissions, and it will rise as nations get richer and build more. It’s mainly because of the energy needed for the high heat process, and the carbon released from the limestone used. It’s one of the leading hard-to-abate sectors, and coming up with an alternative process and cement recipe is firmly on the industry’s agenda. Josie Garthwaite at Stanford University summarises a study that aims to replace … [Read more...]
EU’s Carbon Border Adjustment Mechanism lacks the detail to drive industry’s relocation near clean energy
High emissions industries should be relocated to where the cheap clean energy is. So long as the shipping costs (in terms of price and emissions) aren’t prohibitively high, those locations can be anywhere in the world. To get the calculations right, Carbon Border Adjustment Mechanisms (accounting for the emissions of imported goods) must be harmonised internationally. They must also – crucially – count all relevant emissions. But the EU’s draft … [Read more...]
The EU’s “Fit for 55” package: a primer on the EU ETS and other main policy levers
On July 14 the European Commission will present the much awaited “Fit for 55” legislative package. Lara Dombrowski and Simon Göss at Energy Brainpool have written a very useful primer on what’s at stake for the EU ETS, along with a summary of the other main policy levers that will be decided upon. The authors describe the EU ETS as the central instrument for reducing greenhouse gas emissions. It caps emissions for 10,000 power sector, industrial … [Read more...]
Norway an EV role model? Their pathway is expensive and paid for with oil & gas exports
Norway is an EV leader thanks to a generous pot of tax incentives. Today, battery-electric cars make up more than half of all new car sales in Norway. Schalk Cloete takes a detailed look at what those incentives cost, and how many tonnes of CO2 they avoid. In short, Norway – a major oil and gas exporter - needs to sell over 100 barrels of oil (which emits 40 tonnes of CO2) to pay for the tax breaks it gives EVs to avoid one tonne of CO2. And … [Read more...]
How Clean Energy Standards have driven clean electrification in the U.S.
John Rogers at the Union of Concerned Scientists presents evidence from the U.S. of the effectiveness of using standards to drive clean electrification. In principle it’s simple: set a legal requirement for the percentage of clean electricity. How it’s done depends on the efforts of all the actors affected. 30 states are using different versions of Clean Energy Standards (CES) – the first began in 1983 and more than half of them began before 2004 … [Read more...]
Does new German target mean Coal gone by 2029, Renewables 65% by 2030?
The stiffer emissions targets introduced this month to Germany’s Climate Protection Law - CO2 emissions from the energy industry must fall to 108 Mt by 2030 instead of 175 – point to an even earlier coal phase-out date of 2029, with renewables generating 65% of electricity by 2030. The existing plan had meant coal must be gone by 2038. Michael ClauĂźner, Carlos Perez-Linkenheil and Simon Göss at Energy Brainpool explain why, using their modelling … [Read more...]
EU’s new 15% emissions cut for EVs looks like 2% thanks to four “allowances”
EU regulations for reducing car emissions have been an important driver for getting European manufacturers to go electric and seek a leading position globally. But new rules will slow that progress, according to Transport & Environment (T&E). What look like rules that require a 15% reduction in COâ‚‚ emissions from new cars from 2025 can mean a drop of as little as 2%, thanks to four “allowances”. Heavier average car weight (and electric … [Read more...]
18 energy transition scenarios to watch: where they agree and disagree
A wide range of regions, nations and respected organisations have created net-zero strategies and pathways, but on what do they agree and disagree? Dolf Gielen, Asami Miketa, Ricardo Gorini and Pablo Carvajal at IRENA have done a meta-analysis of 18 recent energy transition scenarios to find out. There is consensus over the main strategies: renewable power generation, and the direct and indirect electrification of end-use sectors – these account … [Read more...]
Aviation should be given target dates for zero-emissions. It’s working for cars and trucks
The French government’s decision to ban some short-haul flights if there is a rail alternative under two and a half hours is only symbolic, says Andrew Murphy at T&E. It would reduce French aviation emissions by only 0.8%. Expanded to rail journeys under five hours and it’s still only 4.5%. Long-haul flying is the much bigger problem, but the resulting emissions are outside of France’s current climate target. Instead of just talking about … [Read more...]
Biden’s Leaders Summit: turning climate commitments into solutions
President Biden's Leaders Summit on Climate last month helped focus minds on making firm commitments to reducing global emissions. As we all know, targets are one thing, credible and realistic solutions are another. To understand the challenge better, Dolf Gielen, Ricardo Gorini and Gayathri Prakash at IRENA break down into themes those areas that need much more effort and, if dealt with successfully, can get us to net zero by 2050: structural … [Read more...]
Germany’s highest court rules climate laws are insufficient, violate rights, unfairly burden future generations
In an unexpected decision widely hailed as historic, Germany's highest court has ruled that the government's climate legislation is insufficient, and lacks detail on emission reduction targets beyond 2030. Sören Amelang, Kerstine Appunn, Charlotte Nijhuis and Julian Wettengel at Clean Energy Wire run through the background and the consequences of the case brought by youth activists and NGOs. Legal experts say the decision “significantly … [Read more...]
China’s car sales target: 40% EVs by 2030 will cost CNY 100bn/year (€13bn, $15bn)
By the end of the 2020s China will phase out EV subsidies and instead rely on a mandate imposed on manufacturers to target 40% of car sales being electric by 2030. Nancy Stauffer at MIT reviews a study that estimates the new rules will result in 66m EVs sold in China in the next 10 years. That will move EVs well into the mainstream and have global consequences. According to the study, the total cost of that transition will be 100bn yuan/year … [Read more...]
Why expensive Buildings Renovations? By the time they’re done the grid will be emissions-free
The big budgets being talked about for the transition require us to decide how much to spend, and on what. Maximilian Auffhammer at the Energy Institute at Haas explains why he thinks a lot of the money being earmarked for buildings renovations would be better spent elsewhere. By the time the renovation wave has successfully “reached the shoreline” in the next few decades buildings will be powered overwhelmingly by clean grids (that’s the plan, … [Read more...]
What is your nation’s “deforestation footprint”? When imports cut down trees somewhere else
Behaviour change is now inextricably linked to the transition and must be part of the world’s emissions reduction strategy, and there are many different types of relevant behaviour and ways to measure the impacts. One is to look at deforestation, caused by chopping down trees to meet our consumer needs. To grasp whose behaviour has to change we need to appreciate to what extent deforestation in places like Brazil, Canada, Liberia, Vietnam etc., … [Read more...]
The Netherlands: a Blue Hydrogen economy now will ease a transition to Green
Barthold Schroot at EBN makes the case for blue hydrogen for the Netherlands now, to minimise emissions and make life easier for green hydrogen later. The country is a big consumer of natural gas that, realistically, cannot be quickly replaced with renewables. So what’s the best alternative to burning that gas and can be introduced the soonest? Green hydrogen production (emissions-free) will take time to reach scale as it needs to piggy-back off … [Read more...]
