Once you have mapped your activities and selected the appropriate tool, you will focus on collecting data activities and emission factors to measure carbon emissions.

# Data activities

You can try to identify the best available data or proxy to do this, and think about how to improve the measurement later. Accuracy is not the primary objective here: a range may be sufficient to enable you to identify the key levers for reducing your carbon footprint. Make sure you define and document your methodology for measuring your carbon footprint baseline, so that you can monitor and fine tune your future reduction action plan.

# Emission factors

You can start with default emission factors from the UN Emission Factor Database (EFDB) which takes into account the 2006 IPCC Guideline for National Greenhouse Gas Inventories and its supplements among others. The Singapore grid emission factor used in the calculation is based on grid emissions published annually by the Energy Market Authority (EMA).

Throughout the process, you will identify areas for progress in data collection and emission factor definitions. Of course, improving your carbon footprint measurement methodology could be part of your future carbon management action plan!

To complete this step, it may be useful to obtain a carbon assurance statement from a third party to verify the accuracy of the GHG emissions data.

ADDITIONAL RESOURCES

Some emissions factors to start with:

- Electricity Emission Factors in Singapore  from Singapore Energy Market Authority (EMA)

- UK Government Conversion Factors for Greenhouse Gas (GHG) Reporting. ‍As this is from the UK, you should take the electricity factors from the EMA link above, but all the other emissions factors can be used.  

- The GHG Protocol's website provides Excel spreadsheets with emission factors.

- Emission Factor for Greenhouse Gas inventories, from The United States Environmental Protection Agency (US EPA) (2015)link to :

- For business air travel carbon emissions, from The International Civil Aviation Organization (ICAO), a specialized agency of the United Nations.
