Project Overview

Measuring progress on emissions reductions helps us track our progress and identify new opportunities to lessen our contribution to climate change. It also helps us understand which areas of change are under our control, and which areas require collaboration with others.

Measure Our Present. Design Our Future.

Since 2018, community emissions have been reduced 22%.

Our goal is to reduce overall emissions by 70% by 2030 from a 2018 baseline.

2020 Community Greenhouse Gas Inventory

What are Greenhouse Gases?

Greenhouse gases (GHGs) absorb radiation from the sun and trap heat in the earth's atmosphere. The more GHGs there are, the more heat is trapped in our atmosphere, leading to global warming and climate change. GHGs measured here include carbon dioxide, methane and nitrous oxide.

About this inventory

Since 2005, Boulder has calculated the community greenhouse gas (GHG) inventory to share our community emissions data. Current inventories now include more GHG sources than earlier inventories, giving a more accurate representation of our contribution to climate change.

The 2020 Community Greenhouse Gas Inventory was calculated following the Global Protocol for Community-Scale Greenhouse Gas Emission Inventories (GPC), the current recognized standard for GHG emissions reporting.

In any given year, factors such as heating and cooling degree days, economic trends and significant local developments impact emissions, requiring careful attention to and consideration of these factors in mapping overall emission trajectories to measure progress and inform next steps in policy and action.

Why measure?

Measuring progress on emissions reductions helps us track our progress and identify new opportunities to lessen our contribution to climate change. It also helps us understand which areas of change are under our control, and which areas require collaboration with others.

More than 70% of global carbon emissions come from cities like Boulder. Hundreds of these cities are measuring GHG emissions to track progress and identify new opportunities to lessen negative climate impacts.
