海外TECH	Engadget	Time to get miserable about the COP28 declaration	https://www.engadget.com/time-to-get-miserable-about-the-cop28-declaration-174527863.html?src=rss	The UN has set out a pathway to avoiding the very worst effects of climate change Earlier this week delegates from around the world ratified a document setting out what we need to do and when Even better the text finally ended the decades long omerta of never talking about the impact fossil fuels have had on our environment It s a landmark moment in history and one that means we can have hope for the future of humanity Unless that is you spend any time examining the substance of the deal to see if the expectations meet the reality Because then you ll see that while it s not all doom and gloom it s certainly not the bold action we really need ContextAll of this took place at the Conference of the Parties COP an annual UN backed conference to build international consensus on climate change Delegates from all UN member states as well as bodies like the EU all meet at a host city for two weeks to speedrun something that looks a lot like a treaty The th such event was hosted in Dubai which attracted plenty of criticism given the emirate s fossil fuel wealth Its president was Sultan Al Jaber UAE minister of industry and uh the head of the Abu Dhabi National Oil company The perception that the event would be a fossil fuel industry stitch up wasn t helped when BBC News reported the UAE secretly planned to use the event to strike new oil and gas deals Or that Al Jaber was quoted by The Guardian saying there was no science supporting the idea that a phase out of fossil fuels was necessary to prevent further warming He later said his comment had been taken out of context and that he supported work to reduce fossil fuel use For all the light and heat around COP it s not as powerful as you might hope or think since there is no real enforcement mechanism The parties should negotiate in good faith but if nations don t actually follow through on their promises there s no mechanism to address it Diplomacy is a delicate art especially with so many moving pieces so maybe we should all learn to appreciate the subtleties That s the positive case The negative one being that COP has been more theater than politics Anne Rasmussen representing the Alliance of Small Island States pointed out her group wasn t even in the room when the declaration was ratified Ironic given that the event was dubbed as the most inclusive COP to date ensuring all voices could participate in the process During the plenary Rasmussen said the text approved in her absence doesn t go far enough in several ways and carries a litany of loopholes for wealthy nations to delay or avoid their responsibilities TL DRThe text opens with a long introductory section admitting that humanity as a whole hasn t been doing a good enough job It admits humans are responsible for raising the Earth s temperature by at least degrees celsius and we re on the hook to fix it And the degrees celsius limit agreed in Paris in isn t going to happen unless we really start putting the work in right now It adds that while the technology is there we haven t made enough use of it and that plenty of small island nations and countries in the developing world will bear the brunt of our inaction The Task at HandBecause we ve dragged our feet for so long the extent of action needed to limit warming to degrees celsius will be stark And degrees isn t maintaining the status quo but the limit that keeps the slew of natural disasters it precipitates from becoming biblical Humanity needs to reduce global greenhouse gas emissions by percent by and percent by To get a sense of that task we emitted around gigatonnes of CO in and now we ve got a decade to cut it by more than a half Should we reach that ambitious target we then need to repeat the same feat even faster to ensure we reach net zero emissions by Even though most climate scientists I ve spoken to feel that the deadline is far too late The LoopholesRasmussen already highlighted that the goals laid out in the text are hazy more guidelines than real processes They re written with the caveat that nations should contribute to the overall goal in a nationally determined manner On one hand that respects their different national circumstances pathways and approaches On the other it allows some nations to pass off insufficient work as them doing their part without consequence Tripling global renewable energy capacity by One of the biggest pledges in the document is to triple renewable energy generation capacity by Data from the International Renewable Energy Agency says that in that figure stood at MW So we ve got six years or so to manufacture and build MW of renewable energy from wind turbines solar panels nuclear and the rest Simple right Not so much Not to denigrate the work that s already been going on but we re nowhere near that level Between and the world got a little under MW of new renewable generation up and running To lay even one finger on the target COP has set down the world needs to be averaging closer to million MW every single year But and here s the thing these figures don t actually feature in the ratified version of the text at all I ve done the math from the figures because that seems relevant but the text itself has no baseline or any frame of reference at all It s conceivable a bad actor could say they ve tripled domestic renewables work from an earlier date or start their count from zero Transitioning away from fossil fuels in energy systemsYou ll have seen plenty of the headlines out of COP commenting this is the first declaration to explicitly mention fossil fuels in its text It s wild to think we ve had nearly three decades of these summits and everyone has chosen to just look the other way until now You can see how tightly these points have been massaged and lawyered to make sure while the elephant in the room has been pointed out it s still very welcome to stay It can continue to knock over the furniture and drop big piles of dung too so long as certain folks keep making money One clause pledges to speed up efforts to phase down unabated coal power which means plants that gesture toward carbon capture aren t targeted The fact that the deal doesn t call for a near instantaneous blanket ban on coal burning boggles the mind given the science at hand After all coal isn t just the worst fossil fuel it s the most environmentally harmful if you burn one ton of coal you ll actually create more than twice that amount of CO Earlier this year the International Energy Agency said that global CO emissions from coal power increased by two percent reaching a new high in Another clause pledges an acceleration toward net zero emission energy systems that use zero and low carbon fuels before And then there s the big one ーa clause talking about a transition away from fossil fuels in energy systems in a just orderly and equitable manner I m enough of a cynic to think those phrases can be bent miles out of shape and the fact there s no benchmarks or enforcement mechanisms means that for now it s all just cheap sweet words Then we ve got a push for other low emission technologies which alongside renewables and nuclear include abatement and removal like carbon capture and low carbon hydrogen It s fair to say that those last two should be treated like the mythical unicorns they really are After all abundant low carbon hydrogen created with renewable energy is a technological cul de sac And while it s fair to say mechanical carbon capture is still relatively new data from the Institute for Energy Economics and Financial Analysis suggests it s a non starter It s hard not to be cynical watching entities with a vested interest in the status quo gesture toward these projects when they re likely to use them as license to stick with business as usual If there s one good point in this part it s that there s a pledge to substantially reduce the volume of non carbon dioxide emissions It specifically namechecks methane a greenhouse gas that is significantly more damaging than CO in the short term There s also a reference to cutting emissions in road transport by pushing infrastructure for low and zero emission vehicles As notable as the mention of fossil fuels was the declaration also recognizes that transition fuels can play a role in facilitating the energy transition while ensuring energy security To you and me that means countries can continue to exploit and burn fossil fuels like natural gas Now gas is better than coal for greenhouse gas emissions but it s a bit like saying you ll only burn down the ground floor of your home rather than the whole thing Not to mention that natural gas is predominantly made up of methane that thing we re also meant to be reducing The restMuch of the work at COP was focused on broader issues including making sure the financial gravity of the situation was addressed There was a lot of negotiation around various monetary tools and funds that could be used to incentivize responsible emissions reduction There were also pledges made for international co operation knowledge sharing and protecting economic growth One clause that did leap out was a pledge to phase out inefficient fossil fuel subsidies that do not address energy poverty or just transitions which is similarly weak in its definition And while there are gestures toward halting deforestation and restoring the natural environment there s little substance One section invites ーinvites ーparties to preserve and restore oceans and coastal ecosystems ReactionsDr Phil Williamson Honorary Associate Professor in Environmental Science at the University at East Anglia said that COP s declaration represents modest political process recognising what has been scientifically obvious for at least years And it s this point that probably needs highlighting given how many Very Serious People will likely hail COP as a landmark Yes it s a massive achievement to finally mention that fossil fuels are the reason we re in this mess But the fact it s taken so long for us to even be confident enough talking about the problem means we now have almost no time to do the work to get us out of it This article originally
