Understanding the Two Main Types of Carbon Emissions

Before selecting the right carbon reduction strategy, it's important to understand where emissions originate.

Operational Carbon

Operational carbon refers to emissions generated during construction activities, including:

1. Diesel-powered excavators, bulldozers, and loaders

2. Material transportation

3. Jobsite generators

4. Equipment idling

5. Temporary site power usage

These emissions can often be reduced through improved fleet management, fuel-efficient equipment, and better project planning.

Embodied Carbon

Embodied carbon includes emissions produced before construction even begins, such as:

1. Cement manufacturing

2. Steel production

3. Material extraction

4. Equipment manufacturing

5. Product transportation

6. Building material disposal

Selecting lower-carbon materials and extending equipment life through refurbishment or purchasing quality used machinery can significantly reduce embodied carbon across a project's lifecycle.

Quick Answer: Operational carbon comes from how equipment and jobsites operate, while embodied carbon comes from the production, transportation, and lifecycle of construction materials and equipment.

1. Improve Heavy Equipment Efficiency

Heavy equipment is often the largest contributor to construction-related emissions. Fortunately, it also offers some of the biggest opportunities for improvement.

Simple operational changes can dramatically reduce fuel consumption without sacrificing productivity.

Best practices include:
