English: In case the message isn't clear enough: sending an A4 letter emits about 25g of carbon dioxide; an e-mail with an attachment is 50g - double - and without an attachment, 0.3g. And e-mails and attachments account for 300 million tonnes of carbon dioxide every year. So, think carefully about the content of the e-mail or the attachment, or even about sending the e-mail at all. I find the prospect of becoming more productive by thinking more environmentally to be something quite exciting. And decisions we can all take involve much more than how many e-mails we send. Do we take a photo or a video on our phones? A photo takes up less storage space. How long do we store that data for? Do we take dozens of pictures at a time and never purge our albums? That has an impact. Not much if we break it down as individuals, but that's the whole thing about tackling climate change; it's the collective. One expert in this field from the M-SParc science park on Ynys Môn suggested to me that you can look at it in terms of our digital consumption and digital retention. We need to think about how much we consume in the first place - how much storage space we need to create for that video or that file or that e-mail or whatever, and then the extent to which we make long-term use of that storage space by not having good housekeeping measures in place to delete things in good time. Again, legislating to mandate assessments of digital carbon footprints of storage, for example, for any organisation could encourage that good practice. We can't just be hoarders of digital content and think there's no consequence to that. And of course there's space that we absolutely need to use up. The development of new artificial intelligence models - hugely intensive in computing power and data storage space. But, we need to be doing that, so we need to shed more of the unnecessary stuff, but we also need to be less carbon-intensive in the way that data centres are run to store that data. Many will need to move to places where it's colder. Shifting into night-time use will save on energy costs but won't help the environment, but shifting to powering from renewable sources does address that. And there's a potential for Wales with our abundance of renewable energy there. At the same time, we need to learn the lessons of countries like Ireland, who face growing concerns over the amount that renewable energy data centres are consuming. Again, legislation could help focus minds. I really could go on, but I'll stop there for now. I think I'm right in saying that this is the first time we've had this kind of debate on this kind of topic, and I look forward to Members' contributions, as we try to give this issue much more prominence, and hopefully, get some legislation behind it, too.
Welsh: Rhag ofn nad yw'r neges yn ddigon clir: mae anfon llythyr A4 yn allyrru tua 25g o garbon deuocsid; mae e-bost gydag atodiad yn 50g - dwbl - a heb atodiad, 0.3g. Ac e-byst ac atodiadau sydd i gyfrif am 300 miliwn tunnell o garbon deuocsid bob blwyddyn. Felly, meddyliwch yn ofalus am gynnwys yr e-bost neu'r atodiad, neu hyd yn oed am anfon yr e-bost o gwbl. I mi, mae'r cysyniad o fod yn fwy cynhyrchiol drwy feddwl mewn ffordd mwy amgylcheddol yn rhywbeth eithaf cyffrous. Ac mae penderfyniadau y gallwn ni i gyd eu gwneud yn cynnwys llawer mwy na faint o e-byst a anfonwn. A ydym yn tynnu llun neu fideo ar ein ffonau? Mae llun yn cymryd llai o le storio. Am ba hyd rydym yn storio'r data hwnnw? A ydym yn tynnu dwsinau o luniau ar y tro a byth yn dileu lluniau o'r albwm? Mae hynny'n cael effaith. Nid yw'n cael llawer o effaith ar lefel unigolion, ond dyna'r holl bwynt am fynd i'r afael â newid hinsawdd; mae'n ymwneud â'r effaith gyfunol. Awgrymodd un arbenigwr yn y maes o barc gwyddoniaeth M-SParc ar Ynys Môn y gallwch edrych arno o safbwynt ein defnydd digidol a'n storio digidol. Mae angen inni feddwl faint rydym yn ei ddefnyddio yn y lle cyntaf - faint o ofod storio sydd angen inni ei greu ar gyfer fideo neu ffeil neu e-bost neu beth bynnag, ac yna i ba raddau y gwawn ddefnydd hirdymor o'r gofod storio hwnnw drwy beidio â chael mesurau cymhennu da ar waith i ddileu pethau mewn da bryd. Unwaith eto, gallai deddfu i gynnal asesiadau gorfodol o olion traed carbon digidol mewn perthynas â storio, er enghraifft, ar gyfer unrhyw sefydliad, annog yr arferion da hynny. Ni allwn barhau i gronni cynnwys digidol a meddwl nad oes canlyniad i hynny. Ac wrth gwrs mae yna le y mae angen inni ei ddefnyddio yn bendant. Datblygu modelau deallusrwydd artiffisial newydd - hynod ddwys o ran pŵer cyfrifiadurol a gofod storio data. Ond mae angen inni wneud hynny, felly mae angen inni gael gwared ar fwy o'r pethau diangen, ond mae angen inni hefyd fod yn llai drud-ar-garbon yn y ffordd y mae canolfannau data'n cael eu rhedeg i storio'r data hwnnw. Bydd angen i nifer symud i lefydd lle mae'n oerach. Bydd newid i ddefnydd gyda'r nos yn arbed costau ynni ond ni fydd yn helpu'r amgylchedd, ond mae newid i bweru o ffynonellau adnewyddadwy yn mynd i'r afael â hynny. Ac mae yna botensial i Gymru oherwydd bod gennym ddigonedd o ynni adnewyddadwy yma. Ar yr un pryd, mae angen inni ddysgu gwersi gan wledydd fel Iwerddon, sy'n wynebu pryderon cynyddol ynglŷn â faint y mae canolfannau data ynni adnewyddadwy yn ei ddefnyddio. Unwaith eto, gallai deddfwriaeth helpu i ganolbwyntio meddyliau. Gallwn barhau, ond rwyf am ddod i ben am y tro. Rwy'n credu fy mod yn iawn i ddweud mai dyma'r tro cyntaf i ni gael dadl o'r fath ar y math hwn o bwnc, ac rwy'n edrych ymlaen at gyfraniadau'r Aelodau, wrth inni geisio tynnu mwy o sylw at y mater, a chyflwyno deddfwriaeth i'w gefnogi hefyd, gobeithio.
