Emissions from burning fossil fuels to make hot cofgee

Scope 1

Emissions from electricity generated on your behalf, to make cofgee

Scope 2

Emissions from activity in your supply chain, so you can have cofgee

Scope 3

How to measure carbon emissions, communicated through the medium

  • f hot beverages

You only get to pick two:

  • avoid using fossil fuels - climate crisis,

remember?

  • use mature hosted services - instead of

building everything yourself

  • avoid oligopoly - diverse ecosystems

are healthy ecosystems

Provider -

We had an energiewende.

We got cheap, green, distributed energy.

What if we had a digitalwende?

Cheap, green, distributed compute?

Programming language

Where appropriate, matching the language to the job can help, because difgerent languages have difgerent features and goals.

The web must be an environmentally sustainable platform “The web, as a whole, is a big source of carbon emissions, because it is a big consumer of power. New web technologies should not make this situation worse. We will consider power consumption and the resulting emissions when we introduce new technologies to the web” W3C Technical architecture group

Process - how your org works

Decisions you make, about where and how you work, that cause emissions.

slide-48

Process - how your org works

Inward - greening of digital projects. Less visible to the end user.
