Title: Lab 2 Carbon Footprint Calculator

Group 1 Lab 2 Carbon Footprint Calculator

Social Groups Engaged in Carbon Calculations
  • Nature Conservancy
  • Is a conservation organization working around the
    world to protect ecologically important lands and
    waters for nature and people.
  • Inconvenient Truth
  • Interactive movie extension intent on pushing a
    specific political agenda - Political will is a
    renewable resource
  • U.C. Berkeley Institute of the Environment
  • The CoolClimate Calculator has been designed to
    help US households evaluate their complete
    climate footprints, including all direct and
    indirect greenhouse gas (GHG) emissions from
    transportation, household energy, food, goods and
    services.

Nature Conservancy
  • Relevant factions involved in production
  • Nature Conservancy
  • Relevant factions involved in the use of this
    technology
  • Nature Conservancy members
  • Concerned public
  • Agenda
  • There is a carbon offset program offered by the
    Nature Conservancy that is prominently displayed
    upon the completion of the interactive tool.
  • As an organization the Nature Conservancy
    carefully avoids the radical leftist fringe and
    tries to remain neutral in its goal of preserving
    land and water for the benefit of natural
    communities. Preservation efforts that inherently
    involve controversy.

Inconvenient Truth
  • Relevant factions involved in production
  • The tool was co-developed by WE and TakePart and
    uses information from the Energy Information
    Administration (EIA), Terrapass, and other
    undisclosed sources
  • Relevant factions involved in the use of this
    technology
  • Concerned public
  • Agenda
  • Offers an opportunity to offset carbon through
    the Native Energy Program.
  • Al Gore remains a political figure and the tool
    continues the political themes that arose in the
    movie.
  • This tool is used to promote special interests.

5
UCB Institute of the Environment
  • Relevant factions involved in production
  • The Berkeley Institute of the Environment (BIE),
    which is co-directed by Professors Dan Kammen and
    Inez Fung.
  • Christopher M. Jones was the lead researcher,
    who, along with graduate student Sally Maki
    developed the tool.
  • Relevant factions involved in the use of this
    technology
  • Concerned public
  • Agenda
  • Academic institution which remains fairly neutral
    in its agenda.

6
Not a stable technology
  • Varying results show that there has not been a
    standard established to calculate carbon
    emissions.
  • Even when the calculators ask similar questions,
    the results among calculators vary by several
    metric tons of carbon for individual output.
  • The methods given for each calculator are very
    vague which makes comparing calculators difficult
    and invalidating calculators very easy.
  • The consistency of all calculators must be
    improved, and transparent methods should be
    readily available to show how the calculator was
    created and how it should be used by individuals.

7
Nature Conservancy
  • Non profit conservation organization, does not
    provide details about who developed their carbon
    calculator or what their instruments for carbon
    measurement are.

8
Inconvenient Truth
  • GHG Protocol Mobile Combustion Tool
  • Energy Information Administration
  • Fuel efficiency of the car from a database
    provided by TerraPass,
  • Electricity bills- we take the mid-point of the
    estimated range and divide by the cost of
    electricity in their state (provided earlier in
    the calculator), which we get from the Energy
    Information Administration (EIA), to come up with
    the electricity used

9
Air Travel
  • Different emissions factors are used for each
    flight length, as follows
  • Short flight .64 lbs/mile
  • Medium flight .45 lbs/mile
  • Long flight .39 lbs/mile
  • Extended flight .39 lbs/mile

Cool Climate Calculator
  • Developed by researchers at the Berkeley
    Institute of the Environment (BIE) at the
    University of California, Berkeley. Default
    expenditure values from data at the Bureau of
    Labor Statistics.

Berkeleys Calculations
  • GHGs/mile gCO2/mi Vehicle manufacturing
    emissions gCO2/vehicle / Vehicle lifetime
    mi/vehicle
  • Miles driven mi/yr / Miles per gallon mi/gal
    Fuel used gal/yr
  • Fuel used gal/yr (direct indirect fuel
    emissions gCO2/gal) Fuel emissions gCO2/yr
  • Miles driven mi/yr (Vehicle manufacturing
    emissions gCO2/ton Vehicle size ton /
    Vehicle lifetime mi) Vehicle manufacturing
    emissions gCO2/yr
  • Total driving emissions Fuel emissions
    gCO2/yr Vehicle manufacturing emissions
    gCO2/yr

13
Feedback
  • In addition to suggesting more accurate measures
    of an individual's carbon emissions, it would be
    helpful if the websites provided
  • application where one could enter specifics about
    each question (more options available to the
    consumer in general)
  • 2. provide resources for the consumer to compare
    which companies they are using as a provider for
    electricity, gas (in the home), and gas used for
    transportation, ect.

14
  • This could make a difference in the amount of
    emissions used due to the policies of particular
    companies because each one is different and
    therefore offers more varieties in terms of
    consumer preference.
  • 3. Also, I would suggest that feedback be given
    to the individual who is tracking their carbon
    emission, to better understand specific steps one
    can do to reduce that amount, based on the
    information given. (Maybe have the information
    blogged or e-mailed to the website for further
    correspondence to the individual.)

15
Calculator Design
  • Different variables are used to calculate
    emissions in tons. Each calculator/technology has
    different standards for calculating the carbon
    footprint of the respondent.
  • Nature Conservancy calculator uses the US per
    capita carbon footprint and subtracts or adds
    points depending on where the respondent lives
    and how they differ from the mean.
  • Another calculator adds up all the components of
    the persons lifestyle and uses these variables to
    find the total carbon footprint. These
    differences in design reflect a lack of a
    generally accepted principle for calculating
    one's carbon footprint.

16
User Engagement
  • Some carbon calculators are adaptable. These ones
    are able to provide a interface which can be
    completed very quickly, but also provides
    additional information that can be used to create
    a more in-depth response.
  • One carbon calculator showed the incremental
    carbon footprint of carbon producing actions,
    this interface gives the user a more in depth
    explanation to their carbon footprint by
    explaining the each of the components of the
    carbon footprint.
  • Most the calculators show how the users footprint
    compares to the nations average and then to the
    world's average. This engages the user by putting
    their carbon footprint in perspective with the
    global community and the nation.

17
What tradeoffs do designers of this technology
make in designing their particular carbon
footprint calculators?
18
  • -Simplicity allows for wider participation but
    less accuracy in results
  • -Need boiler plate answers to certain questions
  • Ex. Living in a certain room, type of house, in
    a particular state, automatically gets you a
    certain carbon footprint

  • Cool Climate (California v. Alaska is 38 v. 41
    at beginning)
  • If data for your city was not available,
    your prices were not adjusted for cost of living
    differences. (Cool Climate)
