cy-gb	Adran 3 – Y broses o osod targedau

en-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/3
cy-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/3/welsh

en-gb	Subsection  (2)  places  a  duty  on  the  Welsh  Ministers  to  exercise  the  power  in subsection (1) to set a long-term target for one of the following pollutants: ammonia, PM10  (defined  in  subsection  (8)),  ground  level  ozone,  nitrogen  dioxide,  carbon monoxide or sulphur dioxide.
cy-gb	Mae is-adran (2) yn gosod dyletswydd ar Weinidogion Cymru i arfer y p#er yn is-adran (1) i osod targed hirdymor ar gyfer un o’r llygryddion canlynol: amonia; PM10 (a ddiffinnir yn is-adran (8)), osôn ar lefel y ddaear, nitrogen deuocsid, carbon monocsid neu sylffwr deuocsid.

en-gb	Any target set under these regulations must, under subsection (3), specify a standard to be achieved and a date by which that standard is to be achieved.
cy-gb	Rhaid i unrhyw darged a osodir o dan y rheoliadau hyn, o dan is-adran (3), bennu safon i’w chyflawni a dyddiad erbyn pryd y mae’r safon honno i’w chyflawni.

en-gb	Subsection (8) explains that these are referred to as the “specified standard” and “specified date” in Chapter 1 of the Act (and these references have the same meaning within these Explanatory Notes).
cy-gb	Mae is-adran (8) yn esbonio y cyfeirir at y rhain fel y “safon benodedig” a’r “dyddiad penodedig” ym Mhennod 1 o’r Ddeddf (ac mae i’r cyfeiriadau hyn yr un ystyr yn y Nodiadau Esboniadol hyn).

en-gb	A standard might be specified, for example, in relation to a concentration of an air pollutant with harmful effects on public health, ecosystems and biodiversity.
cy-gb	Gallai safon gael ei phennu, er enghraifft, mewn perthynas â chrynodiad o lygrydd aer sy’n cael effeithiau niweidiol ar iechyd y cyhoedd, ecosystemau a bioamrywiaeth.

en-gb	The specified standard must be capable of being objectively measured and so the process of setting targets will need to take this into account.
cy-gb	Rhaid gallu mesur y safon benodedig yn wrthrychol ac felly bydd angen i’r broses o osod targedau ystyried hyn.

en-gb	Subsection (4) enables the Welsh Ministers to make provision within the regulations about how the matter in respect of which the target is set is to be measured.
cy-gb	Mae is-adran (3) yn galluogi Gweinidogion Cymru i wneud darpariaeth yn y rheoliadau ynghylch sut y mae mesur y mater y gosodir y targed mewn cysylltiad ag ef.

en-gb	The method of measurement will need to be clear and repeatable.
cy-gb	Bydd angen i’r dull o fesur y mater fod yn glir ac yn un y gellir ei gynnal dro ar ôl tro.

en-gb	Subsection (5) provides that regulations setting the target required by subsection (2) must specify that the target is set to comply with that subsection.
cy-gb	Mae is-adran (5) yn darparu bod rhaid i reoliadau sy’n gosod y targed sy’n ofynnol o dan is-adran (2) bennu bod y targed wedi ei osod i gydymffurfio â’r is-adran honno.

en-gb	Subsection (6) provides that a target is a “long-term target” if the specified date for that target is at least 10 years after the date on which the target is set.
cy-gb	Mae  is-adran  (6)  yn  darparu  bod  targed  yn  “targed  hirdymor”  os  yw’r  dyddiad penodedig ar gyfer y targed hwnnw o leiaf 10 mlynedd ar ôl y dyddiad y gosodir y targed.

en-gb	Subsection (7) explains that a target is set when the regulations setting it come into force.
cy-gb	Mae is-adran (7) yn esbonio bod targed wedi ei osod pan ddaw’r rheoliadau sy’n ei osod i rym.

en-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/4
cy-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/4/welsh

en-gb	This section imposes a duty on Welsh Ministers to set at least one target, in regulations, in respect of the annual mean level of PM2.5 in ambient air in Wales.
cy-gb	Mae’r adran hon yn gosod dyletswydd ar Weinidogion Cymru i osod o leiaf un targed, mewn rheoliadau, mewn cysylltiad â’r lefel gymedrig flynyddol o PM2.5 mewn aer amgylchynol yng Nghymru.

en-gb	This is referred to as a “PM2.5 air quality target” in this section and Chapter 1 of the Act (and this reference has the same meaning within these Explanatory Notes).
cy-gb	Cyfeirir at y targed hwn fel “targed ansawdd aer PM2.5” yn yr adran hon ac ym Mhennod 1 o’r Ddeddf (ac mae i’r cyfeiriad hwn yr un ystyr yn y Nodiadau Esboniadol hyn).

en-gb	Section 5 - Reporting on targets
cy-gb	Adran 5 – Adrodd ar dargedau

en-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/5
cy-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/5/welsh

en-gb	Subsection (2) provides that a PM2.5 air quality target may be a long-term target, but it does not have to be.
cy-gb	Mae is-adran (2) yn darparu y caiff targed ansawdd aer PM2.5 fod yn darged hirdymor ond nid oes rhaid iddo fod felly.

en-gb	Subsection (3) defines PM2.5 as particulate matter with an aerodynamic diameter not exceeding 2.5 micrometres.
cy-gb	Mae is-adran (3) yn diffinio PM2.5 fel deunydd gronynnol sydd â diamedr aerodynamig nad  yw’n  fwy  na  2.5  o  ficromedrau.

en-gb	Subsection (4) provides that the Welsh Ministers must ensure that “ambient air” is defined for the purpose of each PM2.5 target and that regulations under section 2 may contain different definitions for different targets.
cy-gb	Mae  is-adran  (4)  yn  darparu  bod  rhaid  i Weinidogion Cymru sicrhau bod “aer amgylchynol” wedi ei ddiffinio at ddiben pob targed PM2.5 ac y caiff rheoliadau o dan adran 2 gynnwys diffiniadau gwahanol ar gyfer targedau gwahanol.

en-gb	Subsection (5) applies subsections (3) to (4) and (6) to (8) of section 1 to regulations made under this section: see above for an explanation of the effect of these provisions.
cy-gb	Mae is-adran (5) yn cymhwyso is-adrannau (3) i (4) a (6) i (8) o adran 1 i reoliadau a wneir o dan yr adran hon: gweler uchod am esboniad o effaith y darpariaethau hyn.

en-gb	This means, for example, that regulations setting a PM2.5 air quality target must specify the standard to be achieved (which must be capable of being objectively measured) and must specify a date by which that standard is to be achieved.
cy-gb	Mae hyn yn golygu, er enghraifft, fod rhaid i reoliadau sy’n gosod targed ansawdd aer PM2.5 bennu’r safon i’w chyflawni (y mae rhaid gallu ei mesur yn wrthrychol) a rhaid iddynt bennu dyddiad erbyn pryd y mae’r safon i’w chyflawni.

en-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/6
cy-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/6/welsh

en-gb	This section sets out the process that the Welsh Ministers must follow before setting, amending or revoking a long-term air quality target under section 1 and before setting or amending a PM2.5 air quality target under section 2.
cy-gb	Mae’r adran hon yn nodi’r broses y mae rhaid i Weinidogion Cymru ei dilyn cyn gosod, diwygio neu ddirymu targed ansawdd aer hirdymor o dan adran 1 a chyn gosod neu ddiwygio targed ansawdd aer PM2.5 o dan adran 2.

en-gb	Neither a target set to comply with the duty in section 1(2) nor a PM2.5 air quality target can be revoked by regulations made under section 1 or 2 respectively (see subsections (7) and (8)).
cy-gb	Ni all targed a osodir i gydymffurfio â’r ddyletswydd yn adran 1(2) na tharged ansawdd aer PM2.5 gael ei ddirymu gan reoliadau a wneir o dan adran 1 neu 2 yn y drefn honno (gweler is-adrannau (7) ac (8)).

en-gb	Pursuant to subsection (1), before making regulations under sections 1 or 2 the Welsh Ministers must:
cy-gb	Yn unol ag is-adran (1), cyn gwneud rheoliadau o dan adrannau 1 neu 2 rhaid i  Weinidogion  Cymru:

cy-gb	These notes refer to the Ddeddf yr Amgylchedd (Ansawdd Aer a Seinweddau) (Cymru) 2024 (c.2)

en-gb	(a) seek advice from persons they consider to be independent and have relevant expertise; and (b) have regard to scientific knowledge on air pollution.
cy-gb	(a)  ceisio  cyngor  gan  bersonau  y  maent  yn  ystyried  eu bod  yn  annibynnol  ac  yn  meddu  ar  arbenigedd  perthnasol;  a  (b)  rhoi  sylw  i wybodaeth  wyddonol  ynghylch  llygredd  aer.

en-gb	This could include, for example, international evidence on the health and environmental effects of air pollution and the economic, technical and social analyses, and the feasibility of meeting targets.
cy-gb	Gallai  hyn  gynnwys,  er  enghraifft, dystiolaeth ryngwladol ynghylch effeithiau llygredd aer ar iechyd a’r amgylchedd y dadansoddiadau economaidd, technegol a chymdeithasol, a dichonolrwydd cyflawni targedau.

en-gb	Under subsection (2), before making regulations that set or amend a target in respect of a particular pollutant, the Welsh Ministers must have regard to any guidelines for that pollutant published by the World Health Organisation in its most recent global air quality guidelines.
cy-gb	O dan is-adran (2) cyn gwneud rheoliadau sy’n gosod neu’n diwygio targed mewn cysylltiad â llygrydd penodol, rhaid i Weinidogion Cymru roi sylw i unrhyw ganllawiau ar gyfer y llygrydd hwnnw a gyhoeddwyd gan Sefydliad Iechyd y Byd yn ei ganllawiau ansawdd aer byd-eang diweddaraf.

en-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/7
cy-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/7/welsh

en-gb	Subsection (3) requires the Welsh Ministers to set targets they are satisfied can be met.
cy-gb	Mae is-adran (3) yn ei gwneud yn ofynnol i Weinidogion Cymru osod targedau y maent wedi eu bodloni y gellir eu cyflawni.

en-gb	This applies to a target or targets set under the first exercise of the powers under sections 1 and 2 and to any amended targets that are set using those powers.
cy-gb	Mae hyn yn gymwys i darged neu dargedau a osodir y tro cyntaf yr arferir y pwerau o dan adrannau 1 a 2 ac i unrhyw dargedau diwygiedig a osodir gan ddefnyddio’r pwerau hynny.

en-gb	Subsection (9) provides that a target is met if the specified standard is achieved by the specified date.
cy-gb	Mae is-adran (9) yn darparu bod targed wedi ei gyflawni os yw’r safon benodedig wedi ei chyrraedd erbyn y dyddiad penodedig.

en-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/8
cy-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/8/welsh

en-gb	Subsections (4) to (8) set out the process that must be followed in order to revoke or lower a target that has been set under section 1 or 2.
cy-gb	Mae is-adrannau (4) i (8) yn nodi’r broses y mae rhaid ei dilyn er mwyn dirymu neu ostwng targed a osodwyd o dan adran 1 neu 2.

en-gb	Subsection (6) explains that a target is lowered if it replaces the specified standard with a lower standard or replaces the specified date with a later date.
cy-gb	Mae is-adran (6) yn esbonio bod targed wedi ei ostwng os yw’n gosod safon is yn lle’r safon benodedig neu’n pennu dyddiad diweddarach yn lle’r dyddiad penodedig.

en-gb	Pursuant to subsection (4), the Welsh Ministers can only revoke or lower an existing target if they are satisfied that (a) meeting the existing target would have no significant benefit compared with not meeting it or meeting a lower target; or (b) because of changes in circumstances since the existing target was set or last amended the environmental, social, economic, or other costs of meeting it would be disproportionate to the benefits.
cy-gb	Yn unol ag is-adran (4), ni chaiff Gweinidogion Cymru ddirymu neu ostwng targed presennol onid ydynt wedi eu bodloni (a) na fyddai cyflawni’r targed presennol o unrhyw fudd sylweddol o gymharu â pheidio â chyflawni’r targed neu gyflawni targed is, neu (b) yn sgil newidiadau mewn amgylchiadau ers gosod y targed presennol neu ei ddiwygio ddiwethaf y byddai costau amgylcheddol, costau cymdeithasol, costau economaidd neu gostau eraill cyflawni’r targed yn anghymesur â’r buddion.

en-gb	Meeting  a  target  may  have  no  significant  benefit.
cy-gb	Mae’n bosibl na fydd unrhyw fudd sylweddol i gyflawni targed.

en-gb	For  example,  if  meeting  it was anticipated to generate a health benefit, and new scientific evidence has now demonstrated that the same health benefit is achievable through meeting a revised or entirely new target.
cy-gb	Er enghraifft, os y rhagwelwyd y byddai cyflawni’r targed o fudd i iechyd, a bod tystiolaeth wyddonol newydd bellach wedi dangos y gellir cyflawni’r un budd o ran iechyd drwy gyflawni targed diwygiedig neu darged hollol newydd.

en-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/9
cy-gb	http://www.legislation.gov.uk/id/asc/2024/2/section/9/welsh

en-gb	Alternatively, the new scientific evidence may demonstrate that the anticipated health benefit is no longer expected.
cy-gb	Fel arall, gall y dystiolaeth wyddonol newydd ddangos nad yw’r budd a ragwelwyd o ran iechyd yn ddisgwyliedig mwyach.

en-gb	A change in circumstances may, for example, occur as a result of unforeseen reductions in international emission reduction ambitions, assumed when the targets were set, affecting pollutant levels in Wales.
cy-gb	Gall newid mewn amgylchiadau ddigwydd, er enghraifft, am fod gostyngiadau nas rhagwelwyd mewn uchelgeisiau lleihau allyriadau rhyngwladol, a ragdybiwyd wrth osod y targedau, yn effeithio ar lefelau llygryddion yng Nghymru.

cy-gb	These notes refer to the Ddeddf yr Amgylchedd (Ansawdd Aer a Seinweddau) (Cymru) 2024 (c.2)

en-gb	This may significantly reduce the ability of actions taken in Wales to achieve a target, or disproportionately increase the associated costs.
cy-gb	Gall hyn arwain at leihau’n sylweddol allu camau a gymerir yng Nghymru i gyflawni targed, neu gynyddu’r costau cysylltiedig mewn modd anghymesur.

en-gb	Subsection (2) lists the pollutants that the report must, in particular, address. These are (a) ammonia, (b) PM10 (as defined in section 1(8)), (c) ground level ozone, (d) nitrogen dioxide, (e) carbon monoxide and (f) sulphur dioxide.
cy-gb	Mae is-adran (2) yn rhestru’r llygryddion y mae rhaid i’r adroddiad ymdrin â hwy yn benodol, sef (a) amonia, (b) PM10 (fel y’i diffinnir yn adran 1(8)), (c) osôn ar lefel y ddaear, (d) nitrogen deuocsid; (e) carbon monocsid ac (f) sylffwr deuocsid.

en-gb	Subsection (5) requires that before lowering or revoking a target, the Welsh Ministers must publish and lay before Senedd Cymru a statement that explains why they are satisfied that at least one of the grounds in subsection (4) has been met.
cy-gb	Cyn  gostwng  neu  ddirymu  targed,  mae  is-adran  (5)  yn  ei  gwneud  yn  ofynnol  i Weinidogion Cymru gyhoeddi a gosod gerbron Senedd Cymru ddatganiad sy’n esbonio pam y maent wedi eu bodloni bod o leiaf un o’r seiliau yn is-adran (4) wedi ei fodloni.
