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.

Hospitality Case Study

6 mins 50 secs

Key learning objectives:

  • Understand the carbon footprint of a single cocktail

  • Identify where you can make carbon savings in a bar

Overview:

The Sustainable Restaurant Association reports that the hospitality sector is responsible for 15% of the UK’s greenhouse gas emissions so it’s vital for businesses to take action where they can. Dissecting the menu and supply chain is the next challenge. For a bar operator, that means breaking down each drink and each ingredient and going back to its source. For example, a single gin and tonic produces approximately 246 grams of carbon dioxide. Savings can be made with small ingredients adjustments, using alternative packaging for deliveries and switching to energy-efficient refrigeration systems.

Summary
What would the carbon footprint of a single cocktail look like? 

The Margarita cocktail is one of the most popular drinks worldwide. To determine the carbon footprint of a Margarita, we must first analyse the carbon footprint of each ingredient. According to data from My Emissions and uSwitch, the carbon footprint of the ingredients is: 

  • 40 ml of tequila (14g of CO2 emissions) 
  • 20 ml of lime juice (13g CO2 emissions)
  • 20 ml of triple sec (50g CO2 emissions)
  •  Lime wedge (21g CO2 emissions)

This makes the carbon footprint of a single Margarita cocktail approximately 198g of CO2. To put this into perspective, the UK average CO2 emissions per car is 221.4 grams per mile according to the Department of Transport. However, this is only the carbon footprint of the ingredients used to make the drink and doesn't include emissions associated with freezing ice, transporting the ingredients or storage. This would make the carbon footprint of a cocktail even higher.

How can you make a bar more sustainable? 

There are many small adjustments that can be made to minimise the carbon impact of running a bar. Ingredient adjustments would involve using super-juice, olio sacrum and acid-adjusted cordials instead of fresh citrus. Delivery adjustments would involve using alternative packaging to minimise delivery weight. Using local ingredients would reduce emissions and help support local businesses. For ice, consider using reusable ice cubes. Lastly, consider energy-efficient refrigeration systems and storing choice ingredients at room temperature.
