1 MULTIPLE BENEFITS PATHWAYS APPROACH – EXPERIENCE FROM BANGLADESH
Dr. Tanvir Ahmed Bangladesh Univ. of Engineering and Technology (BUET) Asia Pacific Climate Week, July, 2018, Singapore Session: WS 12: Maximizing Benefits in Achieving Global Climate Goals

2 The National Plan for Action on SLCP
The current major sources of black carbon and methane emissions, emission reduction potential in different sectors in Bangladesh A package of priority measures to reduce SLCPs and achieve simultaneously human health and crop yield benefits through improved air pollution, and a reduction in Bangladesh’s contribution to climate change in the near term. Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

3 Black Carbon and Methane Emissions
Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

4 Climate Benefits of SLCP Measures
SLCPs Source Sector Measure Black Carbon Residential Replacing traditional biomass cookstoves with improved biomass cookstoves Waste Reduce open burning of waste Industry Replace traditional brick kilns with improved brick kilns Replace traditional rice parboiling units with improved units Agriculture Reduce crop residue burning in fields Transport Eliminate high emitting vehicles Methane Agriculture (Livestock) Reduce methane emissions from livestock enteric fermentation Reduce methane emissions from livestock manure management Promote landfill CH4 gas collection with combustion or utilization Reduce methane emissions from domestic wastewater Agriculture (Rice cultivation) Alternate wetting and drying (AWD) for rice cultivation Energy Fugitive emission from natural gas transmission and distribution The reduction of SLCPs in Bangladesh that would result from the implementation of these measures could reduce global temperature about Degree Centigrade by 2050 (24% of Bangladesh's contribution). Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

5 SLCP Measures can also have significant health benefits
Traditional cookstoves Traditional brick kilns Open burning of MSW Major sources of black carbon which is a fraction of fine particulate matter, a criteria air pollutant. Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

6 SLCP Measures can also have significant health benefits
SLCP measures can achieve upto 16,274 premature deaths avoided per year in 2050. BC measures has the largest share on these benefits. Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

7 Intended NDC and SLCP Measures
Source Sector Measure Scenario Energy Energy Efficiency (Energy Efficiency & Conservation Master Plan target) NDC (Existing) Power Generation Renewable Energy Industry Improved Brick Kilns Residential Improved biomass cookstoves Supercritical coal power plants NDC (Additional) Transport Road transport fuel efficiency Wind and Solar Improved biomass stoves and LPG use for cooking NDC (Possible) Commercial and Public Services Commercial Energy Consumption Agriculture Alternate Wetting and Drying of Rice paddies Waste Landfill gas capture Organic waste diverted from landfill to composting Efficient rice parboiling units SLCP Action Reduce open burning of crop residues Adopt Euro Standards in road transport CNG conversion Livestock enteric fermentation Domestic Wastewater Natural Gas Reduce leakage from natural gas processing and distribution Reduction of CH4 emissions from livestock, through anaerobic digestion of manure from cattle and poultry Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

8 Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed
NDC measures also contribute to mitigation of air pollutant emissions (BC and NOx) NOx Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

9 Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed
SLCP measure also contribute to meaningful mitigation of GHGs (CO2 and Methane) CO2 Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

10 Climate and Health Benefits under different Scenarios
NDC measures provide a large climate benefits and significant health and agricultural benefits. Climate Premature Deaths avoided vs BAU Adding the SLCP measures improves the health benefits and further reduces Bangladesh's contribution to global temperature increase Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed

11 Why the Multiple Benefits Approach useful?
We can emphasize the benefits of taking certain actions and how these contribute to goals such as positive health outcomes in Bangladesh (the benefit of death avoided from air pollution is justified enough to warrant actions) An alternate justification to NDC actions (development benefit of climate actions) Practical way to engage the general public. Can help prioritize different mitigation measures Can potentially promote regional cooperation (regional common good) the Pathways analysis allows to integrate plans, strategies and policies that were designed for different purposes to see what the overall effect of these different plans are on different impacts Maximum Pathway Practice - Bangladesh Dr. Tanvir Ahmed
