The Science of Climate Change

Climate change is no longer a distant threat or just a possibility, it is now a reality for all of us. In this pathway, Kevin Trenberth, a renowned climatologist, delves into the science behind climate change. He first introduces the climate system, its main components and forces.

Tackling the Plastic Crisis

Plastic pollution is by far the biggest threat to our oceans and this remains an incredibly tough problem to solve. Plastic credits could potentially serve as one of the much needed solutions for this crisis.

The Scale of the Net Zero Challenge

The price of meeting net zero is estimated to be between $100-150 trillion over the next 30 years. Regardless of this cost, we need to reach net zero before climate change does irreversible damage to the environment and the economy.

ESG, Sustainability and Impact Jargon Buster

ESG, sustainability, impact… they all just mean green, right? Not quite. Despite being used often interchangeably, there are distinct differences between these terms.

Reducing Emissions from Software Use

12 mins 36 secs

Overview

There are many ways to reduce carbon impact as an end user. Firstly, check the sustainable credentials of both the software provider and the specific software. You can also take factors into consideration when buying a device - do you need it, does it have an energy rating and can the lifetime use be extended? Lastly, you can reduce the carbon impact of a device by unplugging when not in use, powering down if it must remain plugged in and reducing the brightness of your monitors.

Key learning objectives:

  • Outline how to choose sustainable software

  • Identify factors to consider when buying a device

  • Outline ways to reduce carbon impact of a device

  • Understand the benefits of using sustainable model clauses

Summary
How can you choose sustainable software? 
You can tackle this from two angles: how sustainable is the supplier and how sustainable is the software you are buying? Look at the sustainability credentials of the software provider and ask some of the following questions:
  • Have they set a net zero target and is it aligned with a 1.5c future? Has this been validated and approved by the Science Based Target initiative (SBTi)?
  • Perhaps more importantly, do they have a near-term emission reduction target?
  • Do these targets cover scope 1, 2 and 3 emissions?
  • Do they publish their carbon footprint, for example through the Carbon Disclosure Project (CDP)?
  • Has the footprint been independently verified?
  • Do they have a published climate transition plan and how is this performing?
  • Can the software provider provide a product carbon footprint, showing the greenhouse gas impacts throughout the product’s lifecycle?

What factors should be considered when buying a device? 
  1. Consider the number of devices that you buy and actually use. The more equipment we buy and use, the higher the carbon impact. A workstation with a laptop and 2 monitors will have more than double the impact of a single laptop.
  2. Consider the energy efficiency of the device for example, does it have an energy star rating showing the device operates energy efficiently?
  3. Consider whether the lifespan of the device can be extended. You can utilise simple solutions to extend the lifetime of the device such as battery replacement or screen replacement on phones. You can also use trade-in programmes if you want to buy the latest device or see if the device can be recycled with the manufacturer.

How can you reduce the carbon impact of a device?
  • Avoid standby and fully shut your devices down at the plug 
  • Activate the power saving settings on computers and laptops 
  • Set devices you own to automatically power down
  • Reduce the brightness of your monitors, or turn on dark mode
  • Check what type of energy you are buying and whether you can purchase renewable energy

What are the benefits of using sustainable model clauses? 
  1. These requirements can be tailored to a software provider’s own net zero journey
  2. They can be actioned today to start making greenhouse gas reductions immediately
