Ports are one of major source of PM/BC. Due to busy activities of heavy engines both in land and sea sides, ports emit significant black carbon that pollute its surrounding area.
Since 2012, UNEP has been initiated program to reduce Particulate Matter Black Carbon (PM/BC) emissions from transport sector, particularly heavy duty diesel vehicles and engines. As part of such initiative, UNEP is now conducting similar projects in Southeast Asia (ASEAN), Africa, Latin America and the Caribbean.
Ports are one of major source of PM/BC. Due to busy activities of heavy engines both in land and sea sides, ports emit significant black carbon that pollute its surrounding area. In particular Hub port, where many international, domestic, and intermodal transport activities take place.
A Sustainable clean port program (SCP) should address the 3 following aspects:
- Air Quality improvement
- Institutional framework for SCP implementation
- Co-Benefits and side effects of SCP
The definition of sustainable and clean port program varies depending on the implementation context. clean port program refer mostly to actions to address environment excesses that port operation might cause such as air quality, climate change, water quality, minimum waste dredging, energy conservation, renewable energy, natural resources, and sustainable environmental management systems. Among those issues, air quality program is the most common action for clean port program around the world (IISS, 2010).
Environment regulation or trade globalization, are the main two driving forces behind SCP program. Environment regulation directly drives ports around the world to take action on SCP program. Those regulations were either as a respond to public pressure, an implementation of central government plan, or an implementation of international agreement.
Ports in developing countries implement SCP program mainly as a joint program with other ports in developed country or as an implementation of technical assistance from international donor. However, only SCP program that in line with or enhance development agenda of the local port that proven to be sustain in developing world.
Particulate Matter and Black Carbon (PM/BC) in the Sustainable and Clean Port program
Black Carbon (BC) is particulate matter (PM) that has the strongest light absorbing character. Though it is short lived in the air, because it will quickly change to other substance, but due to its characteristic in absorbing light it has the highest content of energy per mass, that can have energy content millions time higher than CO2.
BC comes from incomplete combustion of fuel (oil, biofuel, and biomass) and being emitted as ultrafine particulate matter (PM2.5). In 2000, global BC emission was mainly came from open burning in the first place, followed by domestic/residential in the second place and industry coupled with transport both in third place. In transport and industry sector, BC mostly came from diesel combustion, especially diesel with from high sulfur content.
Due to its size and heat absorbing characteristic, BC harm our health and our climate. Particulate matter as big as PM2.5 micron is small enough to directly penetrate into blood stream and contaminate it. With energy content millions higher than CO2, it will greatly pollute the atmosphere and impact to our climate.
For long, BC is neither considered in public health and environmental sector, nor included in the climate change actions. In 2012 Climate and Clean Air Coalition (CCAC) initiated a global action to address BC pollutant, in which UNEP became one of the major player in its implementation. From that time, UNEP initiated program in ASEAN started with inventory of BC emission in major source of BC including port.
