September 26, 2022 — The web has a dirty secret. Its carbon footprint is larger than that of global air travel. The energy consumed by the Internet from non-renewable sources makes it the largest coal-fired machine on earth.

This talk offers practical steps to reduce the environmental impact of our work and promote a better future.

December 9, 2021 — This session provides actionable recommendations for practitioners concerned with sustainability: designers, developers, and key players involved in website creation.

Find out what is possible with certain plugins and approaches on WordPress to design and build a greener website. Learn how a greener website benefits not only the planet but also website performance, accessibility, and user experience.

November 6, 2021 — Un sito web che genera in media 10.000 visualizzazioni di pagina al mese consuma 211 kg di CO2 all’anno. Eliminando un singolo kilobyte da un file che viene caricato 2 milioni di volte, possiamo ridurre le emissioni di CO2 di 2950 kg al mese. I fattori da tenere in considerazione per l’analisi sono molteplici: 1. Trasferimento dati sulla rete (peso della pagina web analizzata) 2. Intensità energetica della richiesta (computer, router, datacenter) 3. Fonte di energia utilizzata dal datacenter 4. Intensità di carbonio della rete elettrica 5. Traffico medio del sito web (visualizzazioni di pagina) Un sito web correttamente ottimizzato può quindi contribuire in modo importante alla riduzione di CO2 emessa nell’ambiente.

April 22, 2020 — Every time, you load a website — even this one — a certain amount of carbon is emitted to the atmosphere. These emissions are tied to the amount of energy consumed in the process of delivering the websites content to your browser.
Let’s explore options for both, reducing your own websites greenhouse gas emissions and helping others to do the same by making a third of the web smarter, leaner and more efficient.

June 11, 2019 — With the internet producing 2% of global carbon emissions and growing fast, it’s imperative that all web projects embrace efficiency in order to create a sustainable web for the future.

Having developed a carbon calculator to measure the carbon footprint of websites, we found that encouraging clients to embrace efficiency and commit to reducing their website emissions was surprisingly challenging. To help us understand why, we thought it only right that we practice what we preach and redesign our own website with the aim of improving efficiency and reducing our carbon footprint as far as possible.

This is the story of what we learned in the process, told from the perspectives of a director, a designer and a developer involved in the project.

The outcome was a 75% reduction in carbon emissions, greatly improved page load speed and better user experience. We’ll show what we did in design and development, and how buy in from all stakeholders was crucial to success.

June 22, 2017 — The internet appears clean on the surface but in fact contributes 300m tonnes of CO2 a year, or 1% of global emissions.

WordPress is one of the world’s largest communities of “web creators”, shaping the code, design and content of roughly a quarter of websites worldwide.

Inspired by the landmark agreement made in Paris in November 2015, we should now unite here in Paris in 2017 as a global community to use the power of WordPress to help tackle climate change. We can harness our collective power to publish content that inspires and educates, to design and develop sites that use less energy, to power our hosting on clean renewable energy sources, to run sustainable web businesses and organise green events as a community.

WordPress can lead the way and set an example globally in how to move towards a zero web, and a zero world.
