The main objective of the Environmentally Sustainable Transport (EST) initiative is to built a common understanding across the Asia-Pacific, Africa and Latin America and Caribbean on the essential elements of the EST.
Through this initiative:
(1)The Bangkok 2020 Declaration and Bogotá Declaration will be implemented.
This will lead to:
- accomplish safe, reliable, affordable, efficient, people-centric and environment friendly transport system
-foster economical, social and environmental development
-integrate developing countries in the world economy and contribute the eradication of poverty.
(2)The Africa EST Forum will be established with an objective to address the same for the African region.

UNCRD, in close collaboration with partners, provides substantive support for developing countries by;

- providing advisory services, establishing regional networking, support for capacity building and technical support by organizing forums, trainings and workshops to achieve sustainable development at the local/regional levels;

- motivating government authorities to take the initiative in formulating appropriate policies and programmes towards sustainable transportation through high level policy forums;

- promoting further interagency coordination, collaboration and partnership with the governments to deal with environment and transport issues.

The goals of the Bangkok 2020 Declaration and Bogotá Declaration will be achieved through the promotion of the following strategies to:

(a) avoid unnecessary travel and reduce trip distances: integrating land-use planning and related institutional arrangement, achieving mixed-use development in cities, and using information and communication;

(b) shift towards more sustainable modes: applying non-motorized transport (NMT)component in transport master plan, improving public transport services and implementation of transport demand management (TDM);

(c) improve transport practices and technologies: inducing vehicle technology, fuel quality, freight transport efficiency, inspection and maintenance (I/M), air quality and noise standards; adopting intelligent transport system, zero fatality and energy security policies; monitoring health impacts, adopting social equity, promoting good governance, among others.
