The internet’s infrastructure currently consumes about 10% of the world’s total electricity, with projections suggesting it could reach 20% by 2025.

Online advertising contributes around 10-20% of the total energy consumption of the internet infrastructure, which highlights the substantial environmental footprint of the digital advertising industry, according to Earth.Org. 

These statistics underscore the significant environmental impact of digital advertising, emphasizing the need for more sustainable practices within the industry.

The Basics of PPC Advertising

PPC advertising involves advertisers paying a fee each time one of their ads is clicked. It is a powerful tool for driving traffic and generating leads, and it comes in various forms:

Text Ads: Simple, text-based advertisements that appear in search engine results.

Display Ads: Visual advertisements, including images or animations, shown on websites within a network.

Video Ads: Multimedia advertisements that play before, during, or after video content.

Each type of PPC ad uses different amounts of energy and resources, impacting the environment in unique ways.

The Environmental Impact of Text Ads


There is a misconception that sustainable practices, which often involve more meticulous and thoughtful content creation, don’t impact SEO rankings due to perceived inefficiencies.

Energy Consumption:

Text ads are the most energy-efficient form of PPC advertising. They require minimal data transmission and server processing power, resulting in lower energy consumption. 

Resource Use:

The production of text ads involves fewer resources compared to more complex ad formats. No additional media (images or videos) needs to be created, stored, or transmitted. 

Pros and Cons:

Pros: Low energy consumption, minimal resource use, quick load times, and efficient for mobile users.

Cons: Less engaging compared to visual ads, potentially lower click-through rates.

The Environmental Impact of Display Ads

Energy Consumption:

Display ads consume more energy than text ads due to the need to transmit visual content. The energy required to load and render images or animations on users’ devices contributes to their higher environmental footprint.

Resource Use:

Creating display ads involves the use of graphic design software and digital resources, which have their own environmental costs. Additionally, storing these visual assets requires more server space.

Environmental Benefits and Drawbacks:

Benefits: Higher engagement rates due to visual appeal.

Drawbacks: Increased energy use, higher resource consumption for ad creation and storage.

The Environmental Impact of Video Ads

Energy Consumption:

Video ads have the highest energy consumption among PPC ad types. Streaming video content requires significant bandwidth and server power, contributing to a substantial environmental impact.

Resource Use:

Producing video ads involves extensive resources, including high-definition video equipment, editing software, and significant storage capacity. The carbon footprint of video production is considerably higher compared to text and display ads.

Strategies to Minimize Impact:

Use lower resolution videos to reduce data transfer.

Compress video files to minimize bandwidth usage.

Opt for shorter video ads to lessen server load and energy consumption.

Myths and Misconceptions

Misconception 1: All PPC Ads Have the Same Environmental Impact

Reality: The energy and resource consumption vary significantly between text, display, and video ads.

Misconception 2: Digital Ads Have a Negligible Environmental Footprint

Reality: Digital advertising contributes to data center energy use, which is a growing concern as internet usage increases.

Misconception 3: Sustainable PPC Means Sacrificing Effectiveness

Reality: Sustainable PPC strategies can be highly effective when implemented thoughtfully, with a focus on efficiency and engagement.

Sustainable PPC Practices
