Transcript

  • 1. the Environment Centre (tEC) you . your business .your community Carbon footprinting your site Dr. Derek Moss Dr. Matthew Amesbury
  • 2. the Environment Centre (tEC) you . your business .your community Introduction • More details on calculating a carbon footprint • Scopes 1, 2 and 3 • Setting boundaries • Examples of carbon footprints and energy audits • TEA/COFFEE BREAK!! • Thinking about your carbon footprints
  • 3. the Environment Centre (tEC) you . your business .your community Carbon (CO2) footprinting – more details • CO2 is the main thing we are measuring, but other GHGs (mostly carbon- based) are also included, so it’s called ‘carbon’ footprinting • There is currently no formal definition of ‘carbon footprint’ • Neither is there a formal method of measuring them, but there are several protocols • The currently most widely recognised one is by the World Resource Institute - an independent environmental think tank of scientists, economists and policy makers http://www.ghgprotocol.org/files/ghg-protocol-revised.pdf http://www.ghgprotocol.org/ - calculation tools and guidance notes (by sector)
  • 4. the Environment Centre (tEC) you . your business .your community Carbon footprinting – more details What is the point of them?! • Baseline measurement for comparison with yourself in the future (improvement) • Measurement for comparison with others • Publication So, factors needing to be considered are: 1. Relevance 2. Completeness 3. Consistency 4. Transparency 5. Accuracy www.walkerscarbonfootprint.co.uk
  • 5. the Environment Centre (tEC) you . your business .your community Carbon footprinting – more details What do you actually do? • Decide on what you are going to include • Make measurements of energy use • Convert to units of CO2eq • Report What emissions to include? Operational boundaries (Scope 1, 2, and 3) Who’s emissions to include? Organisational boundaries
  • 6. the Environment Centre (tEC) you . your business .your community Scope 1 – Direct Emissions “direct emissions occur from sources that are owned or controlled by the company” Examples: • On-site combustion (industrial process or heating) • Owned vehicles – work travel, transport • Direct chemical emissions (e.g. methane) General practical application: • Gas/oil bills for heating • Fleet petrol/diesel bills for transport
  • 7. the Environment Centre (tEC) you . your business .your community Scope 2 – Indirect Emissions “accounts for GHG emissions from the generation of purchased electricity used by the company” • When electricity is generated, emissions occur at the power stations • Locally generated electricity (micro-generation or renewable) does not count General practical application: • Electricity bills
  • 8. the Environment Centre (tEC) you . your business .your community Scope 3 – Other Indirect Emissions (put simply, an optional accounting scope which accounts for everything else!) “emissions as a consequence of the activities of a company, but occur from sources not controlled by the company” Examples: • Staff commuting • Embodied carbon of all products purchased • Energy used in transport and operating products • Waste generated, transported and processed
  • 9. the Environment Centre (tEC) you . your business .your community Setting boundaries • Who’s emissions do you include? • For a small business in one office/unit, it’s fairly simple • For a multi-national with interests in many subsidiaries, it is less clear what to include Clearly define the purpose of the measurement www.walkerscarbonfootprint.co.uk
  • 10. the Environment Centre (tEC) you . your business .your community CO2 footprinting examples - tEC We are an environmental charity based in two offices, and with an LPG-fuel car and a diesel-fuel van This is a quick carbon footprint of the operations based in the Southampton office, done as an example
  • 11. the Environment Centre (tEC) you . your business .your community CO2 footprinting examples – tEC Scope 1 Direct emissions from the premises: gas boiler for heating Calendar year total = 26,364 kWh of gas = 5.3 tCO2eq Emissions from company-owned vehicle: Petrol: 120 litres = 0.3 tCO2eq LPG: 620 litres = 0.9 tCO2eq Transport Total = 1.2 tCO2eq Scope 1 Total = 6.5 tCO2eq
  • 12. the Environment Centre (tEC) you . your business .your community CO2 footprinting examples – tEC Scope 2 Electricity used on the premises: Calendar year total = 44,723 kWh of electricity = 22.4 tCO2eq Scope 2 Total = 22.4 tCO2eq A quick Scope 1 and 2 footprint of the Southampton part of our operations is therefore: 28.8 tCO2eq
  • 13. the Environment Centre (tEC) you . your business .your community CO2 footprinting examples – conference A one-off, day long conference. Footprint calculated for the purpose of offsetting Scope 1 – Direct Emissions Gas used for heating the venue on the day, and in the preparation of food: 171 kg Staff travel on conference business: 758 kg Scope 2 – Indirect Emissions Electricity used for lighting the venue on the day, and in powering equipment: 196 kg
  • 14. the Environment Centre (tEC) you . your business .your community Eco-Island conference – Scope 3 conference Food miles – moving the food to the venue: 48 kg Manufacture of products specifically for the conference: 229 kg Delegate travel to the conference – the conference is definitely responsible for this – delegates filled in a questionnaire about their travel, results were analysed and combined Delegate travel emissions: 1568 kg
  • 15. the Environment Centre (tEC) you . your business .your community Eco-Island conference Scope 1: 929 kg conference Scope 2: 196 kg Electrcity Scope 3: 1845 kg Gas Delegate Travel Staff Travel/Deliveries Products Food Total: 2970 kg = 2.97 tCO2eq … which was offset by the distribution of low-energy light bulbs and insulation
  • 16. the Environment Centre (tEC) you . your business .your community Energy Audits – Hospitality Industry A small hotel on the Isle of Wight – simple Scope 1 and 2 footprint Gas for cooking Oil for heating Electricity for lighting Gas and power Electricity Oil Total footprint: 35.2 tCO2eq
  • 17. the Environment Centre (tEC) you . your business .your community Energy Audits – Manufacturing Industry A small manufacturing business doing vacuum forming – a simple Scope 1 and 2 footprint Gas for heating Electricity for lighting, office equipment and processes Electricity Gas Total footprint: 202 tCO2eq TEA/COFFEE BREAK!
  • 18. the Environment Centre (tEC) you . your business .your community Group discussion • Split up into groups by sector (see lists on tables) • Discuss the following issues: 1) Which of your activities contributes most to your carbon footprint? 2) Which areas of footprint do you think are easiest to reduce? • We will briefly discuss results with the larger group
  • 19. the Environment Centre (tEC) you . your business .your community Reducing Your Footprint - Heating Potential Saving Insulation: how well insulated are your premises? 40% Heating: how efficient is your heating system? 20% How draughty are your premises? 15% How well behaved are your staff? - windows 10% Is your thermostat set above 19°C? 8% per °C
  • 20. the Environment Centre (tEC) you . your business .your community Reducing Your Footprint - Offices Potential Saving Are computer monitors left on? 70 kg per year The computers themselves? 100 kg per year Are your lights left on? 50 kg per light Are your drinks machines left on? 600 kg per year Are your printers/copiers left on? Lots Could your staff work from home via VPN? Lots of Scope 3 Could your staff car share? Lots of Scope 3 How much water do you put in the kettle? Lots Monitor your gas and electricity meters – you can’t manage what you don’t measure!
  • 21. the Environment Centre (tEC) you . your business .your community Exercise • Individually, write out the 5 things that you think would reduce your carbon footprint for the least amount of money • Ask us ….. • You’ll have a carbon action plan!
  • 22. the Environment Centre (tEC) you . your business .your community Any Questions? • We are considering offering dedicated carbon footprinting training at tEC. • If you may be interested, please talk to one of us.
