Carbon neutral transport corridors feasibility study (2010-2012)

With support from ADB, ‘economic corridors’ are being developed across the GMS to improve transport connectivity and facilitate trade.  An upsurge in traffic and development along these corridors is leading to increased greenhouse gas emissions and environmental changes. These need to be carefully managed to ensure environmental sustainability.

In 2010, the ‘Carbon Neutral Transport Corridors’ feasibility study was commissioned under the GMS Core Environment Program to investigate the transport sector’s contribution to greenhouse gas (GHG) emissions along the GMS East-West Economic Corridor and identify viable ways to reduce them. This study marked the first attempt by the Core Environment Program to mainstream climate change considerations into the transport sector and engage transport ministries in each country.

The study revealed that transport emissions along the corridor – which connects Lao PDR, Thailand and Viet Nam - were 1.1 million tonnes in 2005, and could triple in two decades if business-as-usual continued. It also found that the freight sector was responsible for 60% of emissions despite providing only 30% of corridor transport activity.

Two approaches to reducing the carbon impact of the freight sector were identified. One focused on mitigating transport emissions by increasing the fuel efficiency of company truck fleets, with estimates suggesting a 15% reduction in fuel use would reduce GHG emissions by approximately 23%. The other approach considered planting forests on degraded land nearby corridor roads. If suitable land would be reforested in one province along the corridor, the study estimated around 60% of emissions could be offset.

Based on the final feasibility study report completed in 2012, the green freight initiative is underway in Lao PDR, Thailand and Viet Nam.

GMS Working Group on Environment 24th Annual Meeting

1st April 2019

The 24th Annual Meeting of the Greater Mekong Subregion (GMS) Working Group (WG) on Environment reviewed the achievements of the GMS Core Environment Program Phase II and discussed the way forward. WGE AM-24 was hosted by the People’s Republic of China’s Ministry of Ecology and Environment (MEE) with support from ADB through the GMS Environment Operations Center.


The WGE AM-24 was followed by thematic discussions that covered the proposed new programs entitled: "GMS Climate Change and Environmental Sustainability Program (CCESP)" and "GMS Sustainable Agriculture and Food Security Program (SAFSP)" which are aligned with three out of seven operational priorities of Strategy 2030 approved by the Asian Development Bank’s (ADB) Board in 2018.


The CCESP will focus on ADB Strategy 2030’s operational priority: tackling climate change, building climate and disaster resilience, and enhancing environmental sustainability, while SAFSP will focus on ADB Strategy 2030’s operational priority: promoting rural development and food security. Both programs will support ADB Strategy 2030’s operational priority: fostering regional cooperation and integration.

Consultation Workshop on GMS Climate Change and Environment Sustainability Program (CCESP)

1 to 2 April 2019

Greater Mekong Subregion (GMS) Climate Change and Environment Sustainability Program (CCESP): The proposed knowledge and support technical assistance (TA) on CCESP will build on the key achievements of two phases of the Core Environment Program and support the implementation of the GMS Core Environment Program Strategic Framework and Action Plan 2018-2022, which was endorsed at the Fifth GMS Environment Ministers’ Meeting held in 2018. The CCESP will focus on creating enabling conditions to leverage additional investment in priority areas such as (i) green technologies and sustainable infrastructure; (ii) natural resources and ecosystem services; and (iii) green growth, climate resilience and disaster risk management.
