Net zero explained
By Stephan Wehr, Vice President of Technical Services, and Matt Beck, Senior Director Carbon Management and Sustainability at The Delphi Group
By the end of 2021, countries responsible for nearly 80% of global GDP will have pledged net-zero emissions by 2050 — or, in the case of China and Brazil, 2060. One-fifth of the world’s largest corporations have set net-zero targets, and that figure is expected to grow exponentially. Many leading companies and organizations here in Canada have made similar pledges, which can be found on Canada’s Net-zero Leaderboard.

What is the difference between a carbon-neutral and a net-zero target?
In a word, none.
Until recently, carbon neutral was the term we used to refer to a goal that balanced (1) the carbon emissions an organization produces with (2) activities that reduce or offset its emissions, so the net result is zero. Net zero is an equivalent term that has gained popularity in recent years, in part because it is used in the Paris Agreement, an international treaty on climate change that was adopted in 2015.
Are all net-zero or carbon-neutral targets created equally?
No. Currently, these targets can be based on different timelines and include different types of emissions – for instance, many companies do not yet include scope 3 (value chain) emissions, which are associated with supply chains and how products and services are distributed and used.
There’s some good news, though: the Science Based Target Initiative (SBTi ), which is a partnership between CDP, the United Nations Global Compact, World Resources Institute (WRI) and the World Wildlife Fund (WWF), is working on a science-based standard for net-zero target setting. Having a global standard will make it easier for investors, customers, and other stakeholders to compare and differentiate between companies.
How do I know if a net-zero target is robust?
Once again, the SBTi comes to the rescue by proposing the following criteria for robust targets:
- In line with what climate science deems necessary to meet the Paris Agreement’s goals and limit warming to 1.5°C
- Always includes value chain emissions, unless there are none
- Prioritizes reducing emissions related to business activities and value chains over offsetting them
- Includes near-term goals with clear action plans on how to achieve them
- Independently assessed
Are there other types of carbon goals out there?
There sure are: some companies are going beyond net zero by committing to remove more carbon from the atmosphere than they release. These commitments have been referred to as ‘carbon negative’ and ‘carbon positive,’ but we like to think of them as restorative goals. For example:
