With much of the debate ahead of the COP26 focused on the energy agenda and how to decarbonise energy supply and reduce demand, the authors of a new report - Net Zero: why resource efficiency holds the answers - warn that focusing exclusively on energy is only half of the solution to tackling climate change associated with carbon emissions.
Quick wins in resource efficiency could help the UK cut its annual emissions by around two billion tonnes of CO₂e, between now and 2050. Improving resource efficiency in goods and services is crucial to tackling climate change, say the report authors, but simple resource efficiency strategies that drive forward action without costly interventions or new technology are being overlooked in work toward net zero.
The report was produced by environmental charity WRAP in partnership with researchers from The Centre for Research into Energy Demand Solutions (CREDS), based at Leeds University. It points out that, between now and 2050, using natural resources more sustainably and extending the useful lifetime of products - and preventing loss or waste - could reduce the greenhouse gas emissions incurred by UK consumption by two billion tonnes of carbon dioxide equivalent. That is the equivalent to eliminating the combined annual territorial greenhouse gas emissions of the UK, France, Italy, Poland, the Netherlands, Belgium, and Austria.
From reducing food loss and waste to moving to more resource efficient business models, and using more recycled materials in manufacturing, the eight strategies put forward are based on real-world projects that have been proven to work. One of the benefits of the strategies is that they can be implemented easily - and straight away. And with the impacts of climate change relating to cumulative emissions over time, the authors are keen to show how their recommendations - which cut carbon today - should be prioritised over those that do not deliver results for years.
Net Zero: why resource efficiency holds the answers shows how simple changes to the way we use materials could reduce UK greenhouse gas emissions by 100 million tonnes CO₂e between 2023 and 2032, equal to taking every car off the road for around 1.5 years. The report also shows how actions we take in the UK can reduce global emissions, with the resource efficiency strategies offering the potential to reduce global emissions by 2 billion tonnes CO₂e between now and 2050, and an additional 89 million tonnes CO₂e avoided towards the 6th Carbon Budget.
WRAP and CREDS believe that their recommendations could offer 50% more territorial greenhouse gas emission reduction in addition to the UK government’s Ten Point Plan for a Green Industrial Revolution, with upward of an additional 100 million tonne CO₂e GHG emissions and help the UK meet its commitment to net zero carbon by 2050. Including reductions overseas, the gross reduction of these strategies could be as high as 364MtCO₂e between 2023 to 2032.
