Emissions and Energy
Each year, Tyler Technologies measures our GHG emissions and energy consumption. We actively seek ways to reduce our carbon footprint, improve energy efficiency, and transition toward renewable energy resources where available. Our 2024 emissions (in metric tons of carbon dioxide equivalent [MT CO2e]) and energy usage (in megawatt-hours [MWh]) are summarized below:

Scope 1
|
Scope 2
|
Scope 3
|
Current Emission Sources
|
Direct emissions from natural gas usage, other fuel consumption, and refrigerants
|
Indirect emissions from purchased electricity
|
Indirect emissions from purchased goods and services, business travel (air travel without radiative forcing), upstream leased assets, and other applicable Scope 3 categories

Tyler’s greenhouse gas inventory is conducted in accordance with the World Resources Institute’s (WRI) and World Business Council for Sustainable Development’s (WBCSD’s) GHG Protocol, including the GHG Protocol Corporate Accounting and Reporting Standard (Revised Edition), the Scope 2 Guidance and the Corporate Value Chain (Scope 3) Accounting and Reporting Standard.
Emissions Table Footnotes:
1. Restatements of historical data due to calculation corrections and changes in accounting methodology are only made if the resulting changes meet significance thresholds as defined in Tyler’s Inventory Management Plan.a The restatements are primarily the result of improvements in data processing, calculation methodology, and industry best practices. Tyler is committed to continuously improving the accuracy of our sustainability reporting. In 2025 the following metrics have been restated due to improved calculation methodology: Scope 3 emissions in Category 1 (Purchased goods and services), Category 2 (capital goods), and Category 4 (Upstream transportation and distribution).
aAn Inventory Management Plan is a methodology document that provides guidance related to the methodology used by Tyler to calculate and maintain our GHG emissions inventory across our operations. The methodology within this document has been written in accordance with the World Resources Institute (WRI) Greenhouse Gas Protocol, a global corporate accounting and reporting standard. The significance threshold for restatement of GHG emissions is defined as 5% within the Inventory Management Plan.
Tyler has chosen to restate any data changes that represent a more than 5% impact to our previously reported values. As such, we are restating our 2023 Scope 3 emissions (Categories 1, 2, and 4) to reflect an improvement in data quality and calculation methodology. The changes to our 2023 inventory include:
- 12.6% reduction in Scope 3 Category 1 emissions,
- 8.7% reduction in Scope 3 Category 2 emissions,
- 5.1% reduction in Scope 3 Category 4 emissions,
- 56.6% reduction in Scope 3 Category 7 emissions,
- 15.2% reduction in total Scope 3 emissions, and
- 13.1% change to our entire 2023 emissions footprint.
2. Travel emissions include air travel and hotel stay and were calculated using a vendor-provided calculation (without radiative forcing).
3. Includes cloud-based emissions
4. Excluding cloud emissions
5. Emissions include air travel only
6. Emissions calculated with radiative forcing
7. Tyler completed the acquisition of NIC in mid-2021, Tyler’s largest acquisition to date. Primary data for NIC was not available; therefore, our 2021 results with NIC are estimated using intensity metrics to reflect the acquisition.
