House of Commons petition Initiated by Brian Brunskill from Regina, Saskatchewan urging the Prime Minister to fund renewable forms of energy production.
Open to Canadians to sign.
www.ourcommons.ca/petitions/en...
Petition to the Prime Minister Whereas: We support our Federal Government’s efforts to make Canada an Energy Superpower and recognize that for many Canadians this means continuing to make major investments in oil and gas infrastructure, including pipelines; For Canadians committed to protecting our biosphere, becoming an energy superpower must also include abundant investment in renewables generation, transmission and storage technologies that will support our low Greenhouse Gas emission economy; For Canadians committed to protecting our biosphere, becoming an energy superpower cannot include any further investment in power generation through burning coal; Canada has some of the best renewable energy resources on Earth, many of which are underdeveloped; and A commitment to matching, dollar for dollar, any federal investment, use of tax-credits or financial support for the development of hydrocarbon-based infrastructure with funding for renewables-based infrastructure would catalyse development of our renewable energy resources. We, the undersigned, Citizens of Canada, call upon the Prime Minister to 1. Provide a legislative foundation that supports our stated commitment to protect our shared environment as we develop energy infrastructure by ensuring that any federal investment, use of tax-credits or financial support for the development of hydrocarbon-based infrastructure, including carbon capture and storage infrastructure, be matched, dollar for dollar, by federal funding for renewables-based infrastructure; and 2. Enact legislation to end coal-fired power generation by 2035.

Folks, venture capitalists, former DC officials, and lobbyists don't want you to talk about climate change anymore. As one pundit I suspect is aligned with this view infamously said, you should instead support the oil & gas industry.

Do with this as you will.

Wait - corporations don't tell the absolute truth with regards to their emissions "reductions" claims? My world is shaken (and boiling, obvs).

"Widespread revisions of self-reported emissions by major US corporations"

www.nature.com/articles/s41...
Article Published: 26 November 2025 Widespread revisions of self-reported emissions by major US corporations Lauren Cohen, Ethan Rouen & Kunal Sachdeva Nature Climate Change volume 16, pages33–36 (2026)Cite this article 758 Accesses 45 Altmetric Metricsdetails Abstract Corporations are important contributors to global greenhouse gas emissions, and stakeholders ask firms to transparently reveal the potential climate impact. However, there are concerns over the consistency and reliability of self-reported emission data. Here we examine the corporate social responsibility reports of major US companies in the last decade. We find that 58% of public firms’ self-reported emissions were later revised, a rate that has remained consistent for a decade. Firms are more likely to understate than overstate, and the amount of understated emissions is more than twice the value of overstated emissions. Factors such as assurance and changes to measurement methodology do not explain the likelihood of revisions, and data providers do not appear to uniformly correct these revisions.

Our project looked at climate neutrality 🇩🇪 2045.
Buildings built in '25 have an operational greenhouse gas emission budget of 6.86 kg CO2e/(m²*a) + embodied 6.41 kg CO2e/(m²*a).

By 2045, these budgets will be reduced to 1.05 and 0.79 kg CO2e/(m²*a), respectively.

This work quantifies the potential of methanol as a versatile platform for both chemical and fuel production. The authors show that certain configurations of the methanol economy can achieve the required emission reductions at costs that remain feasible. The message is clear regarding achieving a fully renewable methanol economy: advancing CO₂-to-methanol technologies is central to the field's progress. As metabolic engineering of microbes emerges as a prominent combative force to mitigate greenhouse gas emissions such as CO₂, the authors provide a rundown of natural and synthetic pathways utilized by microbes to accomplish this task. Various strategies for engineering and optimizing CO₂-fixing microbes have been discussed.

So much trash in this Matt Yglesias NYT rant but this specific bit where has has a go at @doctorvive.bsky.social is absurd even for him.

Eliminating fossil fuels is basic fundamental science shit, not environmentalist shit

archive.ph/02ze4

www.ipcc.ch/report/ar6/s...
A realistic look at the Senate map makes it clear that Democrats’ hopes hinge on states that have important fossil fuel industries. A Democratic Party that is open to responsible stewardship of those states’ natural resources can win majorities and invest in solutions for tomorrow — just as Democratic governors in energy-producing states like New Mexico and Colorado have used oil and gas revenue to finance a goal of universal child care and historic upgrades to conservation and recreation on public lands. The current view from the environmental movement, as expressed by the climate activist and author Genevieve Guenther, is that Democrats should ignore these practicalities because “reducing emissions by some marginal amount while locking in fossil fuel development prevents us from drawing emissions down to (net) zero.” In this approach to making policy, one starts with an end goal — two degrees of warming; global net zero by 2050 — and asks whether some specific new project is consistent with that goal or not. Since this would require a very rapid phaseout of fossil fuel use in rich countries, no new fossil fuel infrastructure is permissible even when the infrastructure would — like new pipelines to the northeastern United States or new liquefied natural gas export terminals — likely make emissions lower by promoting more rapid electrification. This mentality explains why green groups continually find themselves opposing bipartisan congressional negotiations to enact permitting reform legislation that would make it easier to build both renewable and fossil fuel infrastructure. A world that was heading to global net zero in 25 years would not enact such a reform, so it’s unacceptable. Reaching net zero CO2 or GHG emissions primarily requires deep and rapid reductions in gross emissions of CO2, as well as substantial reductions of non-CO2 GHG emissions (high confidence). For example, in modelled pathways that limit warming to 1.5°C (>50%) with no or limited overshoot, global methane emissions are reduced by 34 [21–57]% by 2030 relative to 2019. However, some hard-to-abate residual GHG emissions (e.g., some emissions from agriculture, aviation, shipping, and industrial processes) remain and would need to be counterbalanced by deployment of CDR methods to achieve net zero CO2 or GHG emissions (high confidence). As a result, net zero CO2 is reached earlier than net zero GHGs (high confidence). {3.3.2, 3.3.3, Table 3.1, Figure 3.5} (Figure SPM.5) B.6.3 Global modelled mitigation pathways reaching net zero CO2 and GHG emissions include transitioning from fossil fuels without carbon capture and storage (CCS) to very low- or zero-carbon energy sources, such as renewables or fossil fuels with CCS, demand-side measures and improving efficiency, reducing non-CO2 GHG emissions, and CDR47. In most global modelled pathways, land-use change and forestry (via reforestation and reduced deforestation) and the energy supply sector reach net zero CO2 emissions earlier than the buildings, industry and transport sectors. (high confidence) {3.3.3, 4.1, 4.5, Figure 4.1} (Figure SPM.5, Box SPM.1) B.6.4 Mitigation options often have synergies with other aspects of sustainable development, but some options can also have trade-offs. There are potential synergies between sustainable development and, for instance, energy efficiency and renewable energy. Similarly, depending on the context48, biological CDR methods like reforestation, improved forest management, soil carbon sequestration, peatland restoration and coastal blue carbon management can enhance biodiversity and ecosystem functions, employment and local livelihoods. However, afforestation or production of biomass cro… Energy Systems C.3.2 Net zero CO2 energy systems entail: a substantial reduction in overall fossil fuel use, minimal use of unabated fossil fuels51, and use of carbon capture and storage in the remaining fossil fuel systems; electricity systems that emit no net CO2; widespread electrification; alternative energy carriers in applications less amenable to electrification; energy conservation and efficiency; and greater integration across the energy system (high confidence). Large contributions to emissions reductions with costs less than USD 20 tCO2-eq-1 come from solar and wind energy, energy efficiency improvements, and methane emissions reductions (coal mining, oil and gas, waste) (medium confidence). There are feasible adaptation options that support infrastructure resilience, reliable power systems and efficient water use for existing and new energy generation systems (very high confidence). Energy generation diversification (e.g., via wind, solar, small scale hydropower) and demand-side management (e.g., storage and energy efficiency improvements) can increase energy reliability and reduce vulnerabilities to climate change (high confidence). Climate responsive energy markets, updated design standards on energy assets according to current and projected climate change, smart-grid technologies, robust transmission systems and improved capacity to respond to supply deficits have high feasibility in the medium to long term, with mitigation co-benefits (very high confidence). {4.5.1} (Figure SPM.7) We have options in all sectors to at least halve emissions by 2030 Limiting global warming will require major transitions in the energy sector. This will involve a substantial reduction in fossil fuel use, widespread electrification, improved energy efficiency, and use of alternative fuels (such as hydrogen). “Having the right policies, infrastructure and technology in place to enable changes to our lifestyles and behaviour can result in a 40-70% reduction in greenhouse gas emissions by 2050. This offers significant untapped potential,” said IPCC Working Group III Co-Chair Priyadarshi Shukla. “The evidence also shows that these lifestyle changes can improve our health and wellbeing.” Cities and other urban areas also offer significant opportunities for emissions reductions. These can be achieved through lower energy consumption (such as by creating compact, walkable cities), electrification of transport in combination with low-emission energy sources, and enhanced carbon uptake and storage using nature. There are options for established, rapidly growing and new cities. “We see examples of zero energy or zero-carbon buildings in almost all climates,” said IPCC Working Group III Co-Chair Jim Skea. “Action in this decade is critical to capture the mitigation potential of buildings.” Reducing emissions in industry will involve using materials more efficiently, reusing and recycling products and minimising waste. For basic materials, including steel, building materials and chemicals, low- to zero-greenhouse gas production processes are at their pilot to near-commercial stage. This sector accounts for about a quarter of global emissions. Achieving net zero will be challenging and will require new production processes, low and zero emissions electricity, hydrogen, and, where necessary, carbon capture and storage. Agriculture, forestry, and other land use can provide large-scale emissions reductions and also remove and store carbon dioxide at scale. However, land ca…

Da ist auch nichts mehr zu verhandeln und daher:
Das Bild kombiniert Grafik, Text und Diagramm zu einer eindringlichen, sarkastischen Kritik an den UN-Klimakonferenzen. Oben ist ein buntes, sechseckiges Logo mit den „Main Discussion Topics“ der COP30 in Belém, Brasilien 2025 zu sehen: „Greenhouse Gas Emission Reduction“, „Climate Change Adaptation“, „Climate Finance for the Global South“, „Renewable Energy Technologies“, „Biodiversity Preservation“ und „Climate Justice“. Darunter folgt der wütende Titel in oranger Großschrift: „KEINE KONFERENZEN MEHR!“ Es ist ein Aufschrei gegen die endlosen Gipfel mit „glänzenden Bannern“ und „Reden voller Alarm, Versprechen und Applaus“. Der folgende Text, farblich betont in Blau und Rotbraun, wirft den Verantwortlichen Heuchelei und Stillstand vor: „Die Wissenschaft ist längst bekannt. Die Ziele sind recycelt. Die Versprechen vergessen.“ Die Aktionspläne werden als kosmetische Lügen verspottet – „das Umstellen der Liegestühle auf der Titanic“. Im zweiten Absatz verschärft sich der Ton: Während der Planet brenne und die Biodiversität kollabiere, steige das CO₂ weiter, ebenso wie die Profite der Schuldigen. Die Passage endet mit einer radikalen Forderung: „Kein Geld mehr für Fünf-Sterne-Gipfel, keine Glaubwürdigkeit mehr für einen Prozess, der von den Totengräbern der lebendigen Welt gekapert wurde.“ Der Schlusssatz, fett und rot hervorgehoben, schließt wie ein ultimatumartiger Appell: „Wenn ihr nicht bereit oder in der Lage seid, die CO₂-Produktion zu stoppen, dann stoppt den Zirkus.“ Darunter folgt ein Diagramm mit dem Titel „Global CO₂ Concentration and UN COP Host Countries (1995–2025)“, das die stetig steigende CO₂-Konzentration von etwa 360 ppm auf über 410 ppm zeigt – jede COP-Konferenz markiert als Punkt entlang der steigenden Kurve. Die Botschaft: drei Jahrzehnte leerer Konferenzen, steigende Emissionen, verlorene Zeit. Eine visuelle und rhetorische Abrechnung mit dem Klimaprozess, der zu Symbolpolitik verkommen ist.
