The avail­abil­ity and us­age of dif­fer­ent mo­tor­ized modes of trans­port not only af­fect the en­vi­ron­ment but also con­trib­ute to global warm­ing and cli­mate change. Sim­i­larly, plan­ning, de­sign­ing and de­vel­op­ment of trans­port projects and con­struc­tion of trans­port in­fra­struc­ture also im­pact the en­vi­ron­ment and there­fore en­vi­ron­ment con­sid­er­a­tions and their as­sess­ment is vi­tal. It is well known fact that trans­port has sig­nif­i­cant detri­men­tal ef­fects on both built and nat­u­ral en­vi­ron­ment along with hu­man be­ings. Such ef­fects have life­long im­pacts and there­fore the same may be mit­i­gated at dif­fer­ent stages of plan­ning, de­sign­ing, con­struc­tion and op­er­a­tion. In this con­text, it is im­por­tant to carry out the as­sess­ment of the con­se­quences of pro­grams, poli­cies and projects re­lated to trans­port on en­vi­ron­ment at mi­cro and macro level.

En­vi­ron­men­tal Con­sid­er­a­tions in Trans­port

Trans­port is a means to carry man, ma­te­ri­als, ma­chines, goods, etc. from one lo­ca­tion to another lo­ca­tion by us­ing var­i­ous meth­ods/modes. In fact, it in­volves mo­bil­ity of peo­ple, car­ry­ing of goods, and de­liv­ery of ser­vices from lo­cal level to global level. In other words, such mo­bil­ity needs cre­ation of world class trans­port in­fra­struc­ture, en­vi­ron­men­tal sus­tain­able modes of trans­port and good gov­er­nance. On the con­trar­ily, such trans­port in­fra­struc­ture projects / plan im­ple­men­ta­tion/poli­cies for­mu­la­tion have reper­cus­sions on var­i­ous en­vi­ron­men­tal com­po­nents such as air qual­ity, noise pol­lu­tion, car­bon emis­sion, pub­lic health, etc. There­fore, en­vi­ron­men­tal con­sid­er­a­tions are im­por­tant to as­sess in plan for­mu­la­tion and project im­ple­men­ta­tion which is de­scribed in Ta­ble 1.

Gen­er­ally, ma­jor trans­port in­fra­struc­ture projects need en­vi­ron­men­tal anal­y­sis which is done un­der cer­tain en­vi­ron­men­tal leg­is­la­tions. Fur­ther, it is im­por­tant to es­ti­mate and ad­dress the im­pacts of trans­port in­fra­struc­ture de­vel­op­ment at both mi­cro and meso level. There­fore, Strate­gic En­vi­ron­men­tal As­sess­ment (SEA) and En­vi­ron­men­tal Im­pact As­sess­ment (EIA) are used as step-by step method­ol­ogy for en­vi­ron­men­tal anal­y­sis.
