Illustration showing that Chevron omits more than 90 percent of its emissions in its “net zero” “aspiration”. Though Chevron is quick to proffer its “net zero” commitment as proof of its commitment to address climate change, its “net zero” pledge is 1) only an “aspiration”, as carefully stated on its website; and 2) only applies to its Scope 1 emissions (that result from operating the facilities/equipment/vehicles/buildings that Chevron owns) and Scope 2 emissions (produced from the energy Chevron uses), not its Scope 3 emissions (caused by the end-use of Chevron’s products – sold oil and gas).

“Worthless”: Chevron’s carbon offsets are mostly junk and some may harm – “It’s clear from this report and other research that net zero as a framework opens the door for claims of climate action while continuing with business as usual”

By Nina Lakhani 24 May 2023 NEW YORK (The Guardian) – A new investigation into Chevron’s climate pledge has found the fossil-fuel company relies on “junk” carbon offsets and “unviable” technologies, which do little to offset its vast greenhouse gas emissions and, in some cases, may actually be causing communities harm. Chevron, which reported $35.5bn […]

Atmospheric carbon dioxide hits new peak in 2023, growing at near-record rate – “Not only is CO2 continuing to increase despite efforts to reduce emissions, but it’s increasing faster than it was 10 or 20 years ago”

By Seth Borenstein 5 June 2023 (AP News) – The cause of global warming is showing no signs of slowing as heat-trapping carbon dioxide in Earth’s atmosphere increased to record highs in its annual Spring peak, jumping at one of the fastest rates on record, officials announced Monday. Carbon dioxide levels in the air are now the […]

CO2 equivalent mixing ratio of atmospheric greenhouse gases, 1979-2022. The NOAA Annual Greenhouse Gas Index (AGGI) tracks increases in the warming influence of heat-trapping gases generated by human activity, including carbon dioxide, methane, nitrous oxide, chlorofluorocarbons, and 15 other gases. This illustration depicts the increase in radiative forcing, relative to 1750, of virtually all long-lived greenhouse gases. The AGGI, which is indexed to 1 for the year 1990, is shown on the right axis. Graphic: NOAA Global Monitoring Laboratory

NOAA index tracks how greenhouse gas pollution amplified global warming in 2022 – Methane and nitrous oxide rise near record levels – “Alternative energy sources to replace fossil fuels exist, but cutting emissions associated with producing food is perhaps an even more difficult task”

23 May 2023 (NOAA) – Greenhouse gas pollution from human activity trapped 49 percent more heat in the atmosphere during 2022 than those same gases did in 1990, according to an annual NOAA report. NOAA’s Annual Greenhouse Gas Index, known as the AGGI, tracks increases in the warming influence of heat-trapping gases generated by human activity, […]

Global monthly mean atmospheric carbon dioxide, 1979-2022. The global surface average for CO2 rose by 2.13 parts per million (ppm) to 417.06 ppm, roughly the same rate observed during the last decade. Atmospheric CO2 is now 50% higher than pre-industrial levels. 2022 was the 11th consecutive year CO2 increased by more than 2 ppm, the highest sustained rate of CO2 increases in the 65 years since monitoring began. Prior to 2013, three consecutive years of CO2 growth of 2 ppm or more had never been recorded. The Global Monitoring Division of NOAA/Earth System Research Laboratory has measured carbon dioxide and other greenhouse gases for several decades at a globally distributed network of air sampling sites. This graph shows monthly mean abundance of carbon dioxide globally averaged over marine surface sites. Graphic: NOAA Global Monitoring Laboratory

Greenhouse gases continued to increase rapidly in 2022 – Carbon dioxide, methane, and nitrous oxide rise further into uncharted levels – “Greenhouse gas emissions continue to rise at an alarming pace and will persist in the atmosphere for thousands of years”

5 April 2023 (NOAA) – Levels of carbon dioxide (CO2), methane and nitrous oxide, the three greenhouse gases emitted by human activity that are the most significant contributors to climate change, continued their historically high rates of growth in the atmosphere during 2022, according to NOAA scientists. The global surface average for CO2 rose by 2.13 […]

Gulf of Mexico oil worse for climate than thought, study – “Expanding production in shallow waters, the way it’s been done historically, would have disproportionately high climate impacts”

By Drew Costley 3 April 2023 (AP) – Offshore oil and gas operations in the Gulf of Mexico are releasing far more climate-changing methane than official estimates show, according to a new study published Monday. Using data collected from aircraft in part, climate scientists found the additional methane coming from oil and gas platforms in the Gulf […]

Richest people in UK use more energy flying than poorest do overall – “There is so much social injustice engrained in those who don’t have enough energy”

By Josh Gabbatiss 14 December 2022 (Carbon Brief) – The wealthiest people in the UK burn through more energy flying than the poorest use in every aspect of their lives, according to new research. The analysis of data from 2019 highlights “significant inequalities” in energy use across the country. Those in the top 10% of […]

Unprecedented Arctic wildfires fuel climate warming cycle – “Larger and more intense wildfires could substantially accelerate the release of permafrost carbon into the atmosphere”

By Kat Kerlin 8 November 2022 (UC Davis) – From Sierra Nevada forests to Arctic peatlands, climate warming is turning some long-held carbon sinks into carbon sources as wildfires increasingly send stored carbon up in smoke. In the Arctic, vast amounts of carbon have been locked beneath frozen soil, much of it in peatlands. Climate warming dries […]

Big oil is behind conspiracy to deceive public, first climate racketeering lawsuit says – “What’s different about this case is that we have their enterprise in writing: the decision by rival companies, their front groups, scientists, and associations to act together to change public opinion”

By Nina Lakhani 20 December 2022 (The Guardian) – The same racketeering legislation used to bring down mob bosses, motorcycle gangs, football executives and international fraudsters is to be tested against oil and coal companies who are accused of conspiring to deceive the public over the climate crisis. In an ambitious move, an attempt will […]
