Where to Start

Facts, figures and information that will build a better understanding of what it means to be carbon neutral and help you to implement greener initiatives within your business.

What's a carbon footprint and why does it matter?

A carbon footprint is the total greenhouse gas emissions caused by an individual, organisation or community. Calculating your business's carbon footprint is the first step to becoming carbon neutral. Once you know your carbon footprint and which areas of your business these are split across you can act to effectively reduce emissions.


What are scope 1, 2 & 3 emissions?

The GHG Protocol Corporate Standard classifies a company's Greenhouse Gas (GHG) emissions into 3 scopes:

  • Scope 1 – All direct emissions from owned or controlled sources
  • Scope 2 – Indirect emissions from the generation of purchased energy
  • Scope 3 – All other indirect emissions (not included in scope 2) that occur in the value chain of the reporting company, including both upstream and downstream emissions.


Calculating in detail is the most accurate way of reporting an organisation’s carbon footprint. This allows understanding of more emissions categories, up-to-date emissions factors, and greater insight into how and why emissions are changing (trend analysis) than purely calculating the footprint alone. Streamlined Energy and Carbon Reporting, which some companies have to comply with, is the general UK gov recommended method for voluntary reporting on energy and GHG emissions reporting for businesses.


Does your business need to complete Streamlined Energy & Carbon Reporting (SECR)?

UK government implemented SECR policy on 1st April 2019. The introduction of SECR coincides with the end of the Carbon Reduction Commitment (CRC) Energy Efficiency Scheme. The new regulations will require an estimated 11,900 companies incorporated in the UK to disclose their energy and carbon emissions - a far greater number than were required to act under the CRC.

United Nations Sustainable Development Goals

In 2015 the Sustainable Development Goals were formed when all United Nations Member States adopted the 2030 Agenda for Sustainability Development to provide a shared plan for prosperity for people, peace, and ecological growth for the planet. There are 17 core Sustainable Development Goals (SDGs), which require action now and into the future by all countries – both developed and developing – as a worldwide partnership.

We recommend that businesses pay close attention to the following goals for information on sustainability, climate change and the environment:
