Ymlaen â ni, felly, at brif eitem y cyfarfod y bore yma, sef parhau â'r gwaith o edrych ar effaith amrywiadau yn y dreth incwm genedlaethol ac is-genedlaethol. A gaf i estyn croeso arbennig i'r Athro James Foreman-Peck atom ni bore yma, sydd yn athro economeg ym Mhrifysgol Caerdydd? Mi awn ni'n syth i gwestiynau, os ydy hynny'n dderbyniol. Ac mi wnaf i gychwyn, os caf i, trwy ofyn: mi wnaethoch chi gynnal astudiaeth, wrth gwrs, fel rŷn ni wedi gweld, yn 2019, yn edrych ar ymfudo ac enillion drwy dreth mewn awdurdodaethau is-genedlaethol. Allwch chi efallai ymhelaethu ychydig ar y model y gwnaethoch chi ei ddefnyddio a'r rhagdybiaethau sy'n sail iddo fe?

We'll move on, therefore, to the main item of this morning's meeting, which is to continue to look at the impact of variation in national and sub-national income tax. May I extend a particular welcome to Professor James Foreman-Peck this morning, a professor in economics at Cardiff University? We will dive straight into questions, if that's acceptable. And I will begin, if I may, by asking: you undertook a study, as we have seen, in 2019, looking at migration and tax yields in sub-national jurisdictions. Can you perhaps elaborate a little on the model that you used and the assumption that it's based on?

Diolch, Lywydd. Weinidog, mae yna dîm pwysig arall wedi bod ym Mharis, o flaen y tîm pêl-droed, yr oeddem ni yn ei longyfarch ac yn dymuno'n dda iddyn nhw gynnau bach, sef y tîm wedi'i arwain gan y cyn-Weinidog a aeth i'r trafodaethau newid hinsawdd ym Mharis cyn y Nadolig y llynedd. Yn sgil y trafodaethau hynny, a ydy'r Llywodraeth hyn - eich Llywodraeth chi - yn ystyried ei hunan wedi'i hymrwymo, os nad yn gyfreithlon o leiaf yn foesol, i gyrraedd y targedau a osodwyd yng nghytundeb Paris?

Thank you, Presiding Officer. Minister, there's another important team that's been in Paris, prior to the football team, which we were congratulating and wishing well earlier on, and that's the team led by the former Minister that went to the climate change negotiations in Paris prior to Christmas last year. In light of those discussions, does this Government, your Government, consider itself committed, if not legally, at least morally, to achieving the targets set in the Paris agreement?

Cwestiwn cyntaf. I Weinidog yr Economi. A ydych chi angen unrhyw gliwiau eraill?

First question. To the Minister of the economy. Any other hints you need?

Llywydd, rydym ni'n annog pawb i ddysgu cymorth cyntaf. Cyfrifoldeb ysgolion yw penderfynu os dylen nhw ddarparu addysg cymorth cyntaf i'w disgyblion a'r ffordd orau o wneud hynny. Bydd y canllawiau statudol a fydd yn gysylltiedig â'r cwricwlwm newydd yn darparu y dylai dysgwyr allu ymateb i sefyllfaoedd niweidiol ac ymyrryd yn ddiogel pan fo iechyd pobl eraill mewn perygl.

Llywydd, we encourage everyone to learn first aid. It is for schools to decide if and how best to provide first aid learning for their pupils. The statutory guidance that will surround the new curriculum will provide that learners should be able to respond to harmful situations and safely intervene when others' health is at risk.

Wrth gwrs fy mod. Ni phenderfynwyd arno eto. Felly -

Of course I do. It hasn't been decided yet. So -
