Mae Comisiwn Seilwaith Cenedlaethol Cymru wedi datblygu’r Asesiad Seilwaith hirdymor cyntaf yng Nghymru. Darlun clir ac annibynnol o’r seilwaith sydd ei angen ar Gymru ar gyfer dyfodol teg, gwydn a ffyniannus. Mae’r Asesiad yn edrych ar draws ynni, d\u0175r, trafnidiaeth, cysylltedd digidol a’r economi gylchol i ddeall perfformiad cyfredol, pwysau yn y dyfodol ac anghenion buddsoddi hirdymor.

Gan ddefnyddio tystiolaeth, data ac ymgysylltiad o bob rhan o Gymru, mae’r Asesiad yn tynnu sylw at yr heriau a’r cyfleoedd allweddol sy’n wynebu’r genedl dros y 5\u201380 mlynedd nesaf. Ei bwrpas yw cefnogi penderfyniadau hirdymor gwell, cryfhau gwytnwch i newid yn yr hinsawdd, a sicrhau bod seilwaith yn parhau i wasanaethu cymunedau, yr economi a’r amgylchedd am genedlaethau i ddod.
