Difference between modelled and reported methane intensities by type of company. Modelled emissions are compared with the methane emissions reported by each company in its sustainability reporting or its public communication. The global average ratio on this set of companies is 16.1, with a relative standard deviation of 79.3 percent. Each type of company within this set does not contribute similarly to these global metrics. Integrated companies have the highest average ratio between model and reporting out of all the types of companies, at 19.2 and a relative standard deviation of 64.7 percent, which means that some Integrated companies reporting are much closer to the values for their corresponding model than others. National oil companies (NOCs) have the lowest median ratio with 4.0 but their average is the second highest at 15.2, strongly influenced by one of the companies in the category that has a factor of 51.2, while the remaining 4 have an average of 6.2. Independent companies have the lowest average with 12.6 and a relative standard deviation of 65.2 percent, which shows the importance of the regions of operation in the results of different models.

We used satellite imagery and AI to see who’s keeping their climate pledges – Almost none of the signatories of the Global Methane Pledge are following through on their commitment – On average, companies emit methane intensities 16 times larger than reported

By Antoine Rostand 17 July 2024 (Fortune) – Committing countries or companies to climate pledges doesn’t guarantee that those pledges will be honored. After all, the planet is getting a great deal hotter every year, with the record-breaking temperature in India in May just the latest example. If companies and countries were fully honoring their […]

Approximate depths of subsurface activities. Median (31 m) and 95th (130 m) percentile of water wells (Jasechko & Perrone, 2021); minimum depth of CCS in sedimentary basins (800 m) (Benson & Cole, 2008); shallow limit of oil and gas development (including injection and disposal; 600 m) (Lemay, 2008); geothermal (>2,000 m) (Nardini, 2022). The upper temperature limit for life (80–121°C) (Bar-On et al., 2018; Magnabosco et al., 2018) approximately corresponds to the lowest temperatures required for geothermal power generation (Nardini, 2022; Tester et al., 2021). Circulation of meteoric water occurs up to depths of a few km (McIntosh & Ferguson, 2021) but fluxes are small below 500 m and residence times range from tens of thousands to millions of years (Ferguson et al., 2023; Jasechko et al., 2017; Warr et al., 2021).

Human activities have an intense impact on Earth’s deep subsurface fluid flow – “We know more about the surface of Mars than we do about water, rocks, and life deep beneath our feet”

By Niranjana Rajalakshmi 23 April 2024 (University of Arizona) – The impact of human activities – such as greenhouse gas emissions and deforestation – on Earth’s surface have been well-studied. Now, hydrology researchers from the University of Arizona have investigated how humans impact Earth’s deep subsurface, a zone that lies hundreds of meters to several […]

Why carbon capture is no easy solution to climate change – “Not all technologies are going to be possible in all locations”

By Leah Douglas 27 November 2023 (Reuters) – Technologies that capture carbon dioxide emissions to keep them from the atmosphere are central to the climate strategies of many world governments as they seek to follow through on international commitments to decarbonize by mid-century. But they are also expensive, unproven at scale, and can be hard […]

Carbon credit market confidence ebbs as big names retreat – Voluntary carbon markets shrink in 2023 for the first time in at least seven years

By Susanna Twidale and Sarah Mcfarlane 1 September 2023 LONDON (Reuters) – Voluntary carbon markets have shrunk for the first time in at least seven years, as companies including food giant Nestlé and fashion house Gucci reduced buying and studies found several forest protection projects did not deliver promised emissions savings. Preserving forests is crucial […]

Forests are no longer our climate friends – “As extreme as this year’s wildfire emissions have been, they are just the latest escalation in a multi-decade flood of CO₂ pouring out of Canada’s ‘managed’ forests and forestry”

By David Wallace-Wells 6 September 2023 (The New York Times) – Canadian wildfires have this year burned a land area larger than 104 of the world’s 195 countries. The carbon dioxide released by them so far is estimated to be nearly 1.5 billion tons — more than twice as much as Canada releases through transportation, […]

Carbon emissions projected to 2050 in three scenarios: Accelerated, Net Zero, and New Momentum. BP’s Energy Outlook 2022 uses three main scenarios (Accelerated, Net Zero, and New Momentum) to explore the range of possible pathways for the global energy system to 2050 and help shape a resilient strategy for BP.

BP Energy Outlook 2022 edition – The carbon budget is finite, and it is running out

By Spencer Dale 14 March 2022 (BP) – At the time of writing, the world’s attention is focussed on the terrible events taking place in Ukraine. Our thoughts and hopes are with all those affected. The scenarios included in Energy Outlook 2022 were largely prepared before the outbreak of the military action and do not include any […]

Global Carbon Capture and Storage (CCS) capacity, 2010-2020. Twenty years ago, the fossil fuel industry told you that by today, CCS would capture 5,000 million tons of CO2 per year. Today, the world can barely capture 10. Which is so far off target you can’t even see it on this graph. And when you remember that our global emissions are 36 BILLION tonnes each year, even if it had met its target, it would contribute approximately FUCK ALL. Data: IEA. Graphic: The Juice Media

Honest Government Ad: Carbon Capture and Storage – “CCS is a complex mining process whereby fossil fuel companies inject donations into the arseholes of politicians to delay climate action”

1 September 2021 (The Juice Media) – Hello, I’m from the Australien Government with an important announcement as we enter the next stage of the climate crisis: MASSIVE FIRES, MASSIVE FLOODS, MASSIVE BULLSHIT. As things fall apart and calls grow for us to urgently reduce our emissions we’ve come up with a PR campaign – […]

The global COVID-19 lockdowns caused fossil carbon dioxide emissions to decline by an estimated 2.4 billion tonnes in 2020 - a record drop according to researchers at the University of East Anglia, University of Exeter and the Global Carbon Project. It means that in 2020 fossil CO2 emissions are predicted to be approximately 34 GtCO2, seven per cent lower than in 2019. Emissions from transport account for the largest share of the global decrease. Those from surface transport, such as car journeys, fell by approximately half at the peak of the COVID lockdowns. Total CO2 emissions from human activities - from fossil CO2 and land-use change - are set to be around 39 GtCO2 in 2020. Video: UEA

COVID lockdown causes record drop in carbon dioxide emissions for 2020

11 December 2020 (UEA) – The global COVID-19 lockdowns caused fossil carbon dioxide emissions to decline by an estimated 2.4 billion tonnes in 2020 – a record drop according to researchers at the University of East Anglia (UEA), University of Exeter, and the Global Carbon Project. The fall is considerably larger than previous significant decreases […]

Extreme rainfall variability driving tree growth reductions in western U.S. – “Key Southwest tree species may be at risk as precipitation extremes intensify”

By Rosemary Brandt 2 October 2019 (UA News) – As the Earth’s temperature warms, its hydrological cycle kicks into overdrive – wet years get wetter, and dry years get drier. According to a new University of Arizona-led study, these increased rainfall extremes could have dire consequences for the semi-arid forests of the western U.S. “In […]

It’s getting harder and harder to limit global warming to 2°C – “It is partly this hope in future technologies that delays action”

By Robbie Andrew 23 April 2019 (Robbie Andrew) – The road to 2°C is steep; the road to 1.5°C is a cliff. While it is theoretically possible that we can keep global warming under 1.5°C above pre-industrial temperatures, that task is monumental. In fact, models struggle to generate future scenarios that keep warming below 1.5°C, but can […]
