Abstract
The “Santa Catarina Rural” is a Program co-funded by The World Bank for improvements on 1300 km of low volume rural roads on Southern Brazil. The pioneer project under the program was on the municipality of Santa Rosa de Lima, where the greenhouse gas (GHG) emissions resulting from the road improvement activities as well as the regular traffic were assessed on an experimental basis using the CarbonROAD software application. Here, we show details of the CarbonROAD software application and the construction emissions assessment procedure as well as the mitigating effect of the plants used for compensation. It was found that most of the emissions come from the road improvement work. This includes earthworks, fuel for motor graders, bulldozers and other machines, and materials and gravel extraction, industrialization and transportation, etc. Only a smaller portion comprises regular road traffic. The accumulated emission balance shows that the carbon absorption is larger than construction emissions after just 15 months. The potential for price appraisal of the generated carbon credits is explored.
Highlights
The “Santa Catarina Rural”, a program co-funded by The World Bank is currently being pursued in Southern Brazil
The correct infrastructure design and working plans facilitates the calculation of emission compensation on rural roads
For the Santa Rosa de Lima project the greenhouse gas (GHG) plant absorption pass over emissions after just 1.25 years
Summary
The “Santa Catarina Rural”, a program co-funded by The World Bank is currently being pursued in Southern Brazil. A new experimental design method was developed as existing simplified engineering procedures were not suitable for the present project. It is focused on the municipality of Santa Rosa de Lima, a small rural town 120 km from Florianópolis with around 2000 habitants. As part of the experimental design method, we performed a greenhouse gas (GHG) assessment for the emissions related to the road works by using the software CarbonROAD. It calculates all emissions from the construction per se, and that from maintenance activities and traffic as well. The idea is to calculate a compensation for the emissions caused by the road work and further traffic
