Cambridge Community Wide Greenhouse Gas Inventory 2012
data.cambridgema.gov | Last Updated 3 Nov 2023This dataset contains an inventory of Cambridge's estimated community-wide greenhouse gas emissions for the year 2012. The data was created by DNV-GL, MAPC and the Environmental & Transportation division of the Community Development Department. It was created to establish a baseline for total emissions community wide per the City’s commitment to the Global Covenant of Mayors. It provides a baseline for the City to set reduction goals and track progress towards those goals over time.
This dataset has the following 8 columns:
| Column Name | API Column Name | Data Type | Description | Sample Values |
|---|---|---|---|---|
| Sector | sector | text | The broad economic activities that lead to greenhouse gas emissions. | Stationary Energy Transportation Waste view top 100 |
| Subsector | subsector | text | Narrower, more specific economic activities that lead to greenhouse gas emissions. | Manufacturing Industries and Construction Commercial & Institutional Buildings and Facilities Residential Buildings On-road Rail view top 100 |
| Source | source | text | The fuel or industrial process that leads to greenhouse gas emissions. | Electricity Electricity T&D Losses Natural Gas Nat. Gas. Dist. Losses Fuel Oil view top 100 |
| Scope | scope | number | Greenhouse gas accounting protocols tend to assign a "scope" of 1, 2, or 3 to greenhouse gas emissions. The scope indicates whether the emissions derive from a source that is directly or indirectly controlled by Cambridge. Scope 1: All direct GHG emissions. Scope 2: Indirect GHG emissions from consumption of purchased electricity, heat or steam. Scope 3: Other indirect emissions, such as the extraction and production of purchased materials and fuels, transport-related activities in vehicles not owned or controlled by the reporting entity, electricity-related activities (e.g. T&D losses) not covered in Scope 2, outsourced activities, waste disposal, etc. | 1 3 2 view top 100 |
| Methane Emissions (MT CH4) | methane_emissions | number | Emissions of the greenhouse gas methane (CH4). Units are megatonnes, or one million metric tons. | 0.2111 185.8163 0.1042 11.0643 0.0634 view top 100 |
| Carbon Dioxide Emissions (MT CO2) | carbon_dioxide | number | Emissions of the greenhouse gas carbon dioxide (CO2). Units are megatonnes, or one million metric tons. | 21.6000 4283.8247 7062.8400 82310.3951 367.5838 view top 100 |
| Nitrous Oxide Emissions (MT N2O) | nitrous_oxide | number | Emissions of the greenhouse gas nitrous oxide (N2O). Units are megatonnes, or one million metric tons. | 0.0438 0.0638 0.1508 0.0008 0.0013 view top 100 |
| Carbon Dioxide Equivalent Emissions (MT CO2e) | carbon_dioxide_eq | number | Each greenhouse gas contributes differently to global warming. In order to to compare different sources and sectors, greenhouse gas accounting protocols tend to convert greenhouse gases into carbon dioxide equivalent emissions. For example, the most recent Intergovernmental Panel on Climate Change found one metric ton of methane creates 28 times more atmospheric warming than an equal amount of carbon dioxide over a 100 year period. This is known as methane's "global warming potential" (GWP). To convert from methane to CO2e, we multiple a given mass of methane by its GWP of 28. Nitrous oxide has a GWP of 265. | 25163.6404 4318.8802 2145.4848 14375.5827 967.3385 view top 100 |
