Greenhouse Gas Emissions
This indicator measures the total amount of greenhouse gas (GHG) emissions produced in the CMAP region. GHG emissions are calculated using the International Council for Local Environment Initiatives (ICLEI) Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC) BASIC methodology, which includes all emission from buildings, solid waste, wastewater, and intraregional transportation. Emissions are reported in million metric tons of carbon dioxide equivalent (MMTCO2e).
GO TO 2040 sought to reduce the region’s greenhouse gases by 80 percent, relative to 1990 levels, by the year 2050. This goal is consistent with the stabilization pathway, which is an emissions pathway designed to limit global warming to 2° Celsius (3.6° Fahrenheit).
CMAP is reaffirming this commitment to the stabilization pathway with ON TO 2050. Because the inventory methodology has changed significantly since the GO TO 2040 indicator was created, the targets have been revised accordingly.*
2025: 91.2 MMTCO2e or less
2050: 25.7 MMTCO2e or less
*These targets have been updated to reflect the methodology of the most recent greenhouse gas emissions inventory, which follows the GPC Basic protocol. For more information on how 1990 emissions were calculated, please see this methodology document.
