The Greenhouse Gas Protocol (www.ghgprotocol.org) is the most widely used international accounting tool for government and business leaders to understand, quantify, and manage greenhouse gas emissions. However, while the GHG Protocol includes six main GHG emissions, it does not take into consideration main air pollutants. Measuring air pollutants from energy use (particulate matter (PM), SO2, NOx, CO, depending on the energy type) could be important because
- Air pollution is an important local issue for companies, with local impacts such as reduced health, agricultural yield and haze
- Air pollution reduction is one of the sustainable development benefits of GHG emission reductions, required under Clean Development Mechanism (CDM) projects
- Some air pollutants (black carbon which is part of PM, and ozone) contribute to global warming, and therefore reducing these air pollutants also makes from a climate change perspective
Air pollutants are generated from the same types of energy as GHG emissions and are thus relatively easy to determine. Companies should therefore consider measuring GHG and air pollutant emissions in parallel, preferably integrating air pollutants in a GHG accounting system.
The Clean Air Asia has been collaborating with the Philippine Business for the Environment (PBE), the local chapter of World Business Council on Sustainable Development (WBCSD), to assist industries in establishing a GHG and Air Pollutant Emissions Accounting System and to determine their next steps in managing emissions.
Clean Air Asia developed calculation tools that integrate air pollution and GHG accounting based on AP42, GHG Protocol, UNEP Fleet Management Toolkit, and IPCC Manuals. The ultimate aim is for corporations to adopt integrated accounting systems.
The tool was piloted at San Miguel Corporation, one of the largest companies in the Philippines (for results see http://www.baq2008.org/sp6-mejia). Clean Air Asia and PBE also assisted Petron Corporation - an oil company in the Philippines with the largest refinery (see http://www.petron.com/pdf/petron_SR09FINAL.pdf for results) and Maynilad Company (a major water utility operator in Metro Manila). The tool and the guidance document can be downloaded below.
