Sustainable Web

Our digital carbon footprint

In the digital age, every online interaction, from browsing a webpage to streaming a video, consumes energy and contributes to carbon emissions. The internet accounts for approximately 3.7% of global carbon emissions, a figure that continues to rise with increasing data consumption.

Our commitment
For an energy company like EDP, committed to leading the energy transition, adopting sustainable web practices is not just a technical choice, it's a reflection of our core values and commitment towards a greener and more sustainable future.

Why sustainable web matters

Aligning our digital presence with sustainability goals
By optimizing our website to reduce energy consumption, we demonstrate our commitment to environmental stewardship
Enhancing user experience and efficiency
By simplifying design elements and reducing content, we can streamline operations and reduce server load and costs
Setting industry standards and lead by example
By adopting and promoting sustainable web practices, we set a benchmark for other players in the energy sector

Understanding Carbon Emissions per Page Visit

Every element of a website consume energy. To conduct this assessment on carbon emissions, we use the CO2.js library and the sustainable web design model from the Green Web Foundation.
The sustainable web design model

This model uses data transfer as a proxy indicator for total resource usage, and uses this number to extrapolate energy usage numbers for your application as a fraction of the energy used by the total system comprised of:

  • the use-phase energy of datacentres serving content
  • the use-phase energy network transfering the data
  • the use-phase energy of user device an user is accessing content on
  • the total embodied energy used to create all of the above

It then converts these energy figures to carbon emissions, based on the carbon intensity of electricity from the Ember annual global electricity review.

The carbon intensity of electricity figures for the swd model include the full lifecycle emissions including upstream methane, supply-chain and manufacturing emissions, and include all gases, converted into CO2 equivalent over a 100 year timescale.

This follows the approach used by the IPCC 5th Assessment Report Annex 3 (2014), for the carbon intensity of electricity.
