Your carbon net zero journey

We are here to support you on your carbon reduction journey and empower you to deliver your stated carbon net zero policy aims.

On Tuesday 20 April the UK government announced it will set the world’s most ambitious climate change target into law to reduce emissions by 78% by 2035 compared to 1990 levels.

Whether you are just starting or already underway with your carbon net zero journey, we have a number of solutions that can help you with decarbonisation across your procurement portfolio; from the obvious areas such as energy and fleet, through to areas you might not even consider, such as technology hardware and in the future food and catering.

Carbon net zero podcast

Tune into our podcast to hear our experts and guest speakers share their knowledge on a variety of topics relating to carbon net zero.

We’re working with our customers to understand the biggest carbon net zero challenges and where they are on their decarbonisation journey. We’ve already identified dozens of our agreements that can be used to help with that journey already – from the obvious areas like Fleet and Energy to technology hardware and even, in the future, food.

Understanding carbon net zero

What is carbon net zero?


Sometimes known as net zero carbon or just net zero, this describes a state where any Carbon Dioxide (CO2) or Greenhouse Gas (GHG) emissions left over after decarbonisation are offset by negative emissions, of CO2, of an equivalent amount from the atmosphere, resulting in no net GHG impact.

What does this mean for the UK?


Carbon net zero means that the UK’s total GHG emissions would be equal to or less than the emissions the UK removed from the environment. This can be achieved by a combination of emission reduction and emission removal.

The carbon net zero target requires total decarbonisation of electricity, transport, buildings, industry, and the public sector, with interim targets and legislation to help us get there.

Why is reaching carbon net zero important?


The government has stated that climate change is an existential threat to humanity. Without global action to limit GHG emissions, the climate will change catastrophically with almost unimaginable consequences for societies across the world. 

The public sector is in a unique position of being able to lead the way for the rest of the country. Our activities directly influence the behaviours of the citizens we serve across the UK to deliver real change. 

Carbon is vital for us to live and survive. The world does need Carbon to exist but when there is too much Carbon it causes the environmental issues we have seen around the world. This has been recognised by the United Nations and the Paris Climate agreement for 2050. We understand the long term impact of this increase in Carbon and it underlines our plans on why we need to take action now.

In recognition of the risks to the UK and other countries, the UK became, in 2019, the first major economy to implement a legally binding net zero target

Key dates and events

What does the 2050 target mean?


The UK has legislated to end its contribution to global warming by 2050, in effect reducing greenhouse gas emissions by at least 100% against 1990 levels. 

A pathway for the public sector to halve non-traded emissions from buildings (direct heat and power, plus any fugitive emissions from coolants or refrigerants) by 2032 has been outlined in the Clean Growth Strategy.
