In May the U.S. Environmental Protection Agency proposed new rules regulating carbon emissions from fossil fuel-fired power plants. Here, four experts from the Center for Strategic and International Studies â Cy McGeady, John Larsen, Kyle Danish and Mathias Zacarias â make their assessment and point at the wide-ranging implications. The main issues covered include CCS, hydrogen-fuelled generation, state clean energy standards, carbon pricing, … [Read more...]
The history of evidence of CO2-driven climate change starts in the mid-1800s
Marc Hudson at the University of Sussex gives us a fascinating review of the history of climate change science. While the Intergovernmental Panel on Climate Change (IPCC) was established in 1988, experimental evidence that CO2 traps heat dates back to the mid-1800s. The first predictions of global warming caused by humans came in 1895. The big change in perception took place in 1953. Canadian physicist Gilbert Plass (an academic whose career also … [Read more...]
Oil & Gas can meet 2030 net-zero target for only $600bn, quickly recouped. But itâs still not happening, warns IEA
The IEA summarises its 33-page report âEmissions from Oil and Gas Operations in Net Zero Transitionsâ. The IEA says the oil and gas sector needs ÂŁ600bn up front to meet its 2030 target of a 60% reduction in emissions. Thatâs only 15% of the sectorâs record 2022 energy-crisis windfall income. A small price increase and savings should recoup that money âquicklyâ, says the IEA. The IEA not only maps a way to limit the global average temperature rise … [Read more...]
EU Carbon Removal Certification Framework: new rules to turn greenwashing into genuine removals
The EU Carbon Removal Certification Framework intends to drive forward technological and natural carbon removals, and prevent greenwashing through robust standards and certification procedures. Itâs to deal with the existing poorly monitored carbon removals market: the lack of oversight, transparency, trustworthiness, and genuine climate impact (additionality) of projects and certificates. Simon Göss at carboneer looks at the current proposals, … [Read more...]
CO2 emissions from Land Use: country-level data for turning âemittersâ into âsinksâ
Until carbon capture technologies take off (if at all!), the worldâs CO2 removals depend entirely on nature. Clemens Schwingshackl, Wolfgang Obermeier and Julia Pongratz at Ludwig Maximilian University of Munich, writing for Carbon Brief, review the latest data on âcarbon fluxesâ which measure whether the land is a net âsourceâ of carbon or a âsink.â Flux measurements are categorised: deforestation, forestation, wood-harvest emissions, removals … [Read more...]
Poorly defined âefficiencyâ incentives birthed the SUV. Beware the same mistake with âclean energyâ jobs, âdomesticâ batteries + more
Financial support for the transition needs clear and carefully chosen definitions of what qualifies for that support. Getting it wrong leads to unintended consequences, some which may not reduce emissions, explains James Sallee at the Energy Institute at Haas. Ever wondered why SUVs and big cars proliferated after the 1970s in the U.S. (and are on roads all over the world now)? The 1970s oil crisis triggered new rules that penalised fuel … [Read more...]
Li-ion Grid Batteries arenât always the best replacement for Gas Peakers
Gas peakers need to be replaced with something cleaner. Like grid batteries. But the question is âwhenâ, says Maximilian Auffhammer at the Energy Institute at Haas. Summarising his co-authored paper, he explains that a review of 19 gas peakers in the U.S., replaced with Li-ion grid-scale batteries, reveals only 5 make economic and climate sense (i.e. a positive net present value after including monetised climate and human health impacts). … [Read more...]
Geothermal Heat Pumps: can new U.S. âIRAâ support make it go mainstream?
Bidenâs Inflation Reduction Act in the U.S. is meant to drive forward the best clean energy solutions. To help make sure geothermal heat pumps play their fullest role, RMI has done a study of its benefits as well as published guides on how developers can take advantage of the various new laws and support mechanisms. Lauren Reeg, Mike Henchen, Chris Potter and Chris Stone at RMI start with a summary of the technology and its applications, before … [Read more...]
Turning Ethanol productionâs CO2 by-product into E-Fuels using Wind power
With vast open spaces, Midwest states in the U.S. produce millions of gallons of ethanol from corn as well as thousands of kilowatt-hours of electricity from wind farms every year. Research led by NREL is working on using wind power to drive electrolysers that turn the ethanolâs CO2 by-product into e-fuels, explains Erik Ringle at NREL. A typical 50 million-gallon-per-year ethanol plant releases 14 tons of CO2, a natural by-product of … [Read more...]
IPCC AR6 report reveals a bigger impact at lower temperatures than previously predicted: health, crops, species loss +more
Published in March, the IPPCâs AR6 Synthesis Report on Climate Change updates its predictions of the effects of temperature rises. It starkly concludes that those temperature rises will have a bigger impact at lower temperatures than previously predicted. Charlotte Edmond, writing for the World Economic Forum, picks out five charts from the report to illustrate the point: the range of likely temperature rises; global map of change in temperature, … [Read more...]
IEAâs global âCO2 Emissions in 2022â report: by sector, fuel, region, heating +more
The IEA has published âCO2 Emissions in 2022â, giving estimates of CO2 emissions from all energy sources and industrial processes globally. Emissions from energy combustion increased by 423 Mt, while emissions from industrial processes decreased by 102 Mt. Emissions from various sources (sector, fuel, region, heating, etc.) are broken down, with reasons for why the change happened. The report is part of the IEAâs first global stocktake of the … [Read more...]
Adding ordinary baking soda to concrete production can cut 15% of its CO2 emissions
Concrete production makes up 8% of global CO2 emissions. Half comes from the fossil energy used to make it (which, hopefully, can transition to clean power), and the other half comes from the CO2 that escapes during the chemical transformation. David Chandler at MIT describes research there that shows how simply adding sodium bicarbonate (yes, the baking soda you put in your cookies) during the early stages of production can remove, by … [Read more...]
IPCCâs latest AR6 synthesis report lacks urgency and realism. Its own numbers say so
Kevin Anderson at the University of Manchester explains his deep disappointment in the recently released and influential IPCC AR6 synthesis report. Even the mainstream media criticised the lack of urgency in the language. Andersonâs objections go further. He says the reportâs own figures show net-zero must be reached by 2040, not the âearly 2050sâ as stated. Anderson goes on to criticise the modelling used as the standard, saying it is formulated … [Read more...]
The problem with CO2e: we need separate emissions data for each climate pollutant (methane, soot, etc.)
Currently, we measure non-CO2 emissions by converting their impact into the CO2 equivalent over a 100-year period. The problem is that other pollutants can have their worst impact well within 100 years, like methane (the first 20 years is when the impact of methane is worst). Though CO2 has caused the most warming, other short-lived pollutants have contributed nearly half of the total, particularly methane, black carbon from soot, and some … [Read more...]
EU: data shows RussiaâUkraine war has not increased Coal and emissions. Itâs quite the opposite
The Russian gas crisis has not resulted in the return of coal and high emissions in Europe, says Lauri Myllyvirta at CREA. He presents the figures that show quite the opposite. Coal returned, as expected, with the post-Covid rebound, but peaked in September 2022 below its pre-Covid level, and has been falling since along with emissions. Meanwhile, high gas prices caused by Russiaâs cut-off has kept gas demand low and, more importantly, driven the … [Read more...]
