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 2020 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 (€13bn, … [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...]
Netherlands: gas phase-out transition must tackle the geopolitical implications of importing from Russia
Until recently, the Netherlands has had no major concerns regarding natural gas security of supply. That’s just as well, given gas plays a big role primarily in the generation of heat: 90% of buildings and 40-50% of industrial heat are based on gas. Now, decarbonisation plans to cut its own gas production as well as consumption brings with it major dilemmas. Irina Patrahau and Lucia van Geuns at The Hague Centre for Strategic Studies present a … [Read more...]
Updated NDCs: World committing to 0.5% emissions cuts by 2030. It should be 45%
The latest national climate pledges, submitted over the new year, show that the world is nowhere near meeting our emissions reductions goals. Analysis of the 48 updated “nationally determined contributions” (NDCs) submitted so far (everyone must submit by the end of this year), covering nations responsible for 29% of global emissions, shows we will have 0.5% lower emissions in 2030 compared to 2010. That’s way off the target 45% reduction needed. … [Read more...]
How the global ”carbon budget” is calculated, and predictions improved
What is the world’s remaining “carbon budget”? Or, how much more CO2 can the Earth take before we know we’ll miss our 1.5oC (and 2oC) goals for 2050. Making those calculations is not easy and IPCC benchmark estimates inevitably include levels of uncertainty in the final answer. Kasia Tokarska at the ETH Zurich Institute and Damon Matthews at Concordia University summarise their research that narrows down that uncertainty, making life a little … [Read more...]
Aviation and Shipping emissions: will Biden take on the challenge?
William Todts at Transport & Environment is very worried about the Biden administration’s approach to aviation and shipping emissions. The signals are that the U.S. wants to work through the International Civil Aviation Organization (ICAO) and the International Maritime Organization (IMO). But they have neither the ability nor the means to spur technological breakthroughs. That matters, because it’s only the use of alternative fuels that can … [Read more...]
Wide variations in National Energy and Climate Plans: how can the EU seriously budget for emissions reductions?
The EU has big and growing ambitions for emissions reductions by 2030: down 40% below 1990 levels, increasing the share of renewables to 32% of final energy consumption and improving energy efficiency by 32.5% above business-as-usual. These targets will be further revised as the more ambitious goal of cutting emissions by 55% by 2030 becomes legally binding. This means the EU as well as individual nations must estimate the cost of meeting these … [Read more...]
Buildings Renovation in Germany: success story or potential failure?
The German Federal Association of Housing and Real Estate Companies (GdW) has claimed that money and effort spent on the nation’s buildings renovations have not worked. But Andreas Rüdinger at IDDRI has looked into the evidence and concluded that the opposite is the case. CO2 emissions from the residential sector in 2018 were 37% lower than in 1990. Though final energy consumption was broadly stable, that’s because efficiency gains were offset by … [Read more...]
E-mobility in Germany: a record year but still way off target
In the past few months Germany has seen record levels for electric car registrations. But will this rising trend be enough to meet the government’s target of 10 million electric cars by 2030? To answer the question Naemi Schink and Simon Göss at Energy Brainpool look at the data, proposed new regulations, and funding. Though the number of electric cars has grown by over 360% in the last year there are currently only 240,000 EVs and 200,000 … [Read more...]
Carbon Offsetting via old wind and solar farms is no way to reduce emissions
Companies can offset their emissions by buying carbon credits, where the money goes to fund clean energy projects. But the carbon credit market includes credits for very old projects. This is a foolish waste, explain Mark Maslin and Simon Lewis at UCL (UK). The market must be based on the principle of additionality: the money should be aimed at projects that would not have happened otherwise, thereby causing emissions reductions that would not … [Read more...]
