The benefits of this are that emissions will be reduced due to an experience not making assumptions or developing unnecessary features (wasting resources), and being more specific about how you might reduce a product or service's environmental impact.",
							"Privacy": "Assessing the needs of visitors will help you comply with privacy laws like GDPR, and anonymous analytics alongside test data can also be used to improve privacy.",
							"Social Equity": "Improved user-experience often means products or services work better for visitors on older devices, in low-bandwidth environments, those with older devices, those in restrictive countries, those who speak different languages, and those with other potential barriers to accessing content. This reduces emissions as less e-waste will be produced if the need for newer equipment becomes less of a priority.",
							"Accessibility": "Understanding the needs of your visitors through accessibility and trauma-informed research will help you prioritize which inclusive design improvements need to be implemented to enhance an already accessible product or service.",
							"Performance": "Identifying what visitors require through research and analytics will reduce the potential for technical debt along the product's lifespan, which will help reduce emissions as developers will spend less time building a product with unnecessary features. It can also be used to identify bottlenecks in the user-experience that are causing visitor abandonment. Fixes can be measured and tested against each other, and the benefits of improvements can result in fewer emissions.",
							"Economic": "Knowing your audience has financial benefits, as they are more likely to purchase your product or service if it meets their requirements. Quantitative data analysis can identify potential cost savings by reducing data payload sizes where optimizations can be made.",
							"Conversion": "If a product matches an audience's requirements, they will be likely to use it regularly and this will increase its popularity and gain trust, word of mouth, and social standing."

Ensuring you comply with ethical privacy practices and avoiding such patterns will avoid potential legal conflicts. You also reduce additional data being sent among the providers of tracking and advertising data.",
							"Accessibility": "Dark and deceptive design patterns often intentionally block or hide access to information, which especially undermines the experience of people with disabilities who use assistive technologies. By avoiding them, you will give those with accessibility needs justification to trust your brand. Furthermore, avoiding unsustainable or carbon-intensive implementations will prevent making any existing situations worse.",
							"Performance": "Interference with the user-interface (such as removing the ability to copy text) causes unnecessary friction and forces the visitor to spend more time on the page to work around the barrier put in place. This uses additional energy as they try to find a solution onsite, elsewhere, or give up entirely. Using ethical, non-disruptive coding practices will speed up interactions within your website.",
							"Economic": "Ethical websites incentivize customers to whitelist your website on ad blockers.",
							"Conversion": "Avoiding dark and deceptive patterns will likely result in fewer complaints. A classic example of this is the use of CAPTCHAs which can disrupt the visitor, cause accessibility barriers, and reduce the legitimate use of your product or service."

As such, this will reduce complaints and annoyance, which can help increase customer retention. Also, user-interface consistency improves visitor trust as individuals will recognize familiar components within your design and know how to utilize them, and this can improve conversion rates as it will lower the rates of abandonment."

If individuals wish to use older devices (or cannot upgrade due to cost) or do not wish to upgrade as frequently, it will reduce the amount of e-waste that enters the system.

Additionally, planned obsolescence is one of the biggest contributors to e-waste on the planet. Extending the lifespan and improving digital device compatibility within your site's service plan, can improve sustainability and slow the upgrade cycle which results from sluggish digital experiences.",
							"Social Equity": "More compatible products and services that last longer helps to reduce the digital divide, which can be a key issue in cases where income inequality, infrastructure robustness, and other factors play their part (and open your work to new markets). Similarly, because progressive web applications use established web standards, they are available to more people than more cost-prohibitive closed systems (Apple App Store, Google Play, etc).",
							"Accessibility": "The fourth pillar of Accessibility is robustness. By incorporating accessibility into early prototypes, it becomes a priority for project teams throughout a product's lifecycle. Broken source code can also (in specific cases) impact assistive technologies (such as screen readers) and how they can read content to individuals with visual disabilities. Ensuring semantic code can provide an equal, error-free experience to all.",
							"Performance": "Incompatible code has an energy cost, when it's non-standard, deprecated or doesn't work on a device it can take additional time to render as it is usually un-optimized for the environment, which will put pressure on the CPU and waste the consumer's battery. Using modern Web standards will help your website run fast in modern browsers.",
							"Economic": "Product teams benefit from time savings and improved quality, organizations see cost reductions as less refactoring is required due to increased stability, and users benefit from greater trust and potentially lower product costs and maintenance fees as upgrades may not be required as frequently.",
							"Conversion": "More compatible products and services that last longer can potentially increase conversion rates due to the lower rates of abandonment and a wider market audience that can use a barrier-free version of the product or service."
