Waqtigan xaadirka ah, hoolka saldhigga tareenada dhulka hoostiisa mara iyo hawo-qaadista iyo nidaamka qaboojinta inta badan waxaa ka mid ah laba nooc: habka hawo-mareenka iyo mashiinka qaboojinta hawo-qaboojinta. Nidaamka hawo-mareenka farsamada ayaa leh mugga hawo weyn, kala duwanaansho heerkul yar, iyo raaxo liidata; munaaradda qaboojinta ee mashiinka qaboojiyaha iyo nidaamka qaboojinta ma fududa in la habeeyo oo isticmaalka tamarta waa weyn yahay. Isku darka habka hawo-mareenka farsamada iyo tignoolajiyada qaboojinta uumi-baxa, ayaa la soo jeediyay in la isticmaalo hawo qaboojinta tooska ah iyo hababka qaboojinta ee hoolka saldhiga tareenka dhulka hoostiisa mara iyo madal, inta badan sifooyinka soo socda:

1. Isticmaal hababka hawo-qaadista iyo qaboojinta si aad u buuxiso shuruudaha heerkulka iyo qoyaanka ee hoolka saldhigga tareenada hoose iyo goobta;

2. Looma baahna in la dhigo munaaradda qaboojinta;

3. Waxay yarayn kartaa aagga is-dhaafka ah ee marinka hawada si loo badbaadiyo booska;

4. Isticmaal xaddi badan oo hawo nadiif ah oo isticmaal sifaynta qoyan si aad u wanaajiso tayada hawada gudaha ee dhismaha dhulka hoostiisa.

Waqtigan xaadirka ah, tareenada dhulka hoostiisa mara ee Madrid, tareenka dhulka hoostiisa mara ee London, iyo tareenada dhulka hoostiisa mara ee Tehraan ee dibadda ayaa qaatay uumi toos ah iyo qaboojinta hawo-qaadista iyo nidaamyada qaboojinta. Waxaa jira saddex nooc oo kala duwan: uumi iyo qaboojinta qalabka qaboojinta buufinta, uumi qaboojinta tooska ah ee hawo qaboojinta, iyo uumiga hawada-conditioning mobile. Codsigu wuxuu gaadhay saameyn qaboojin wanaagsan.

Cimilada gobollada waqooyi-galbeed ee dalkaygu waxay leedahay hawo qallalan oo qani ah. Waqtigan xaadirka ah, Lanzhou, Urumqi iyo meelo kale waxay tixgeliyeen isticmaalka isticmaalka uumi qaboojinta qaboojinta iyo hababka qaboojinta si ay u qaboojiyaan hoolalka saldhigga tareenada iyo goobaha si ay u qaboojiyaan si loo gaaro ujeedada badbaadinta-carbon-yar iyo hagaajinta tayada hawada.

Marka lagu daro isticmaalka tooska ah ee qaboojinta uumiga si loo qaboojiyo hawada saldhigga, iyadoo la adeegsanayo tignoolajiyada qaboojinta uumiga si loo xakameeyo heerkulka sare iyo biyaha qabow ee soo kabashada kulaylku sidoo kale waa jihada muhiimka ah ee codsiga goobta tareenka dhulka hoostiisa mara. Nidaamka qaboojiyaha wuxuu xoojiyaa biyaha, dib-u-warshadaynta xoogga leh, kaabi biyaha uumiga luminta nidaamka buufinta dib-u-warshadaynta kulaylka, oo si buuxda u isticmaala tamarta khasaaraha. Tignoolajiyadan waxaa lagu dabaqay Mashruuca Dib-u-dhiska ee Guangzhou Metro.
