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.

Game Changing New Technology for Forest Protection in Viet Nam

28th February 2018

Every day, tens of thousands of rural folks get together in small groups to patrol Viet Nam’s forests. On their rounds they record evidence of illegal logging, hunting, and other forms of encroachment. They assess the condition of the forests that they are protecting, keeping an eye out for recent landslides and signs of animals.
