Cutting methane emissions from gas production is a major part of the worldâs strategy to limit temperature rises. The IEA says we need a 77% drop in methane emissions by 2030. The question is how to target and enact globally the required incentives and regulations that favour âdifferentiatedâ low-methane-emissions gas. Regulating international trade sounds like a great starting point, as an importer like the EU can twist the arm of anyone who … [Read more...]
The 10 big problems with simply replacing fossil cars with electric
The planned rapid transition to electric vehicles has major challenges. Schalk Cloete complies them into a list of ten, including: preserving our car-centric cities preserves its inefficiencies and societal costs; it works against much of the personal âbehaviour changeâ we need; though BEVs (battery electric vehicles) are better in cities, when infrastructure costs are included they are less efficient than hybrids and modern ICEs for many driving … [Read more...]
COP26 accepted the science like never before. It should make a difference
Leading scientists, writing for Carbon Brief, explain how COP26 gave far greater recognition to science than any of the previous COPs. The scientific evidence from the latest IPCC reports was explicitly acknowledged in the Glasgow Climate Pact. That is a significant advance, say the authors. Decision-making guided by science can focus quantitively on carbon budgets, temperatures, climate change, the causes, and therefore the emissions-reductions … [Read more...]
Paris Agreement âGlobal Stocktakeâ should focus on individual nations too
Itâs time for national governments to focus on the short-term domestic actions needed to meet their 1.5°C goals, argue Anna PĂ©rez CatalĂ , Henri Waisman, Marta Torres Gunfaus and Ariadna Anisimov at IDDRI. Analyses of emissions gaps at a collective and global level wonât be enough, the current purpose of the Global Stocktake (GST) of the Paris Agreement. The first GST runs from 2021 to 2023 and the process will be repeated every 5 years. The … [Read more...]
COP26 and the Glasgow Pact: a summary of achievements, and shortfalls
Experts from around the world summarise their reaction to the outcomes of this yearâs UN climate summit, COP26, including the Glasgow Climate Pact agreed by all 197 countries attending the talks. Each expert covers their area of interest: overall targets, greenhouse gas emissions, fossil fuel finance, nature conservation, transportation, cities and buildings, energy sector transitions, science and innovation, and gender equality. The overall … [Read more...]
Vehicle charge zones: too high, and driver detours can increase emissions
Vehicle congestion charge zones are a way of taxing drivers for the emissions they create. They have great potential to steer polluters towards shorter and/or fewer journeys, and towards cleaner fuels. But these schemes have received too little attention among analysts. âCordon zonesâ are found in big cities like London, Stockholm, Milan and Singapore and the rules are kept very simple. Journey length is rarely, if ever, taken into account. … [Read more...]
Fulfilling the Global Methane Pledge: âpolluter paysâ, more electrification, less gas
At COP26 the U.S. and the EU led a global pledge to slash methane emission by 30% by 2030. Methane makes up at least one-quarter of all greenhouse gases, and is more than 80 times more damaging than CO2 over a 20-year period. Success in cutting these emissions would be a major step towards meeting our 1.5°C goals. But far from declining, 2020 saw methane emissions grow at the fastest rate in 40 years. The increased use of natural gas (mostly made … [Read more...]
Behaviour Change: strategies and case studies for reaching net-zero by 2050
Technological solutions on their own are unlikely to deliver emissions reductions at the speed and scale required to reach net zero by 2050. Daniel Crow, Insa Handschuch, Gabriel Saive and Leonie Staas at the IEA look at a suite of policy-driven citizen âbehaviour changesâ that should be used to bridge the gap. The impact will be greatest in advanced economies where energy intensity is highest. Meanwhile, in emerging economies the good habits put … [Read more...]
Will COP26 set right the booming Carbon Offset Market
Carbon offsetting is when a company, rather than cut its own emissions, pays someone else somewhere else to cut their emissions. It has always been controversial because it has two main problems. Buying carbon credits means you arenât putting the effort in to cut emissions yourself. And the risk of double-counting: when the company reports it has cut emissions, and so does the âsomeone elseâ. A third problem exists too: measuring whether the … [Read more...]
UNEP 2021 Emissions Gap report: only 11 countries have net-zero targets enshrined in law
Zeke Hausfather at Carbon Brief summarises the UNEP 2021 Emissions Gap report, released last week. It explores the impact of the net-zero emissions pledges of nations, and the âgapâ between them and the Paris targets. As COP26 gets started, 136 countries either have some form of commitment to a net-zero target or are considering it. Of those, 49 plus the EU have a firm net-zero commitment. But only 11 countries have targets enshrined in law. … [Read more...]
How much Carbon Capture will Germany need? Both nature-based and technological
Yet more studies have been published that show Germany needs carbon removal to meet its emissions targets. Simon Göss and Hendrik Schuldt at cr.hub add two, from the German Energy Agency and the Ariadne report (funded by the German Ministry of Education and Research), to those that already exist to shine more light on a carbon capture pathway. The main observation is that nature-based solutions (LULUCF: land use, land use change and forestry) … [Read more...]
PET: a toolkit to make existing Coal plants more efficient
Many nations are struggling to phase out coal. Some, like China, are heavily dependent on it, and have more plants in the pipeline to ensure energy security and keep prices low. In other words, a lot of coal will remain in operation for the medium term. Given that, it makes sense to make them more efficient while they are in use. Daisy Chi at ECECP looks at a new set of tools â the Plant Efficiency Toolbox (PET) - that can analyse and optimise a … [Read more...]
Aviation, Steel, Shipping CEOs ask COP26 to back their decarbonisation pathways
The seven âhardest to abateâ industries together account for 30% of global greenhouse gas emissions. They are aviation, steel, shipping, cement, aluminium, trucking and chemicals. John Matson at RMI explains how a growing number of sector-leading corporates in aviation, steel and shipping are now openly backing net-zero pathways. He quotes CEOs and top executives (ArcelorMittal, United Airlines, Trafigura) on what they say they are determined to … [Read more...]
Chinaâs energy crisis: the problems with coal exit, emissions targets, and a command economy
China is also suffering from an energy crisis. Major industries have had to restrict production, and reports abound of candle-lit dinners, traffic lights failing and people getting trapped in elevators. Its effect has also been global, with Apple, Tesla, Microsoft and Dell saying itâs hitting their supply chains. As Jun Du at Aston University explains, Chinaâs drive to cut coal has collided with post-Covid resurgent demand and an unusually hot … [Read more...]
IEA WEO 2021 message to COP26: 40% of clean energy goals will cut costs
The IEAâs latest World Energy Outlook was published on Wednesday. This yearâs WEO-2021 is released earlier than usual to inform COP26 and, for the first time, is available for free to ensure the widest possible audience. Simon Evans at Carbon Brief offers his summary of the 386-page report, quoting relevant numbers and charts. He first points to the new scenario, Net-Zero Emissions by 2050 (NZE), as the IEAâs recognition that this is what … [Read more...]
