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.

Introduction to Life Cycle Assessments

10 mins 5 secs

Overview

Human production models have evolved to be unsustainable. We emit substances that end up impacting human health and biodiversity and consume non-renewable resources such that future generations will not have access to them. All these impacts are affected by how we consume resources from nature, and how we emit substances to it. Life cycle assessment (LCA) is an internationally standardised, science-based, quantitative method for assessing impacts, evaluating decisions, making better decisions, and reporting on the benefits. The ISO 14040 defines four distinct stages to an LCA: goal and scope definition, inventory analysis, impact assessment and interpretation.

Key learning objectives:

  • Define a life cycle assessment

  • Outline the steps of the LCA process

Summary

What is a life cycle assessment (LCA)? 

Life cycle assessment is an internationally standardised, science-based, quantitative method for assessing impacts, evaluating decisions, making better decisions, and reporting on the benefits.

How do you do a life cycle assessment? 

The ISO 14040 defines four distinct stages to an LCA: goal and scope definition, inventory analysis, impact assessment and interpretation.

1. Goal and scope definition

We must spell out what we are measuring, what we intend to find out, how far we will go with each of the threads, and how we will deal with data quality and uncertainty. 

2. Inventory analysis

This entails collecting data from the life cycle of our product. For example, how much of each material, process, energy or chemical do we have as input or output? 

3. Impact assessment

This is where we convert all that information into environmental impacts. In practice, we end up with numeric values for each of the environmental impacts we are measuring. 

4. Interpretation 

We interpret the results.
