The world is falling dangerously short of the ambition that is needed to secure a safe future climate, according to new analysis by PwC, and as a result we need to fight to prevent every fraction of a degree of warming.
PwC’s latest Net Zero Economy Index shows that a year-on-year decarbonisation rate of 17.2% (up from 15.2% last year) is now required to limit global warming to 1.5°C above pre-industrial levels - seven times greater than what was achieved over the last year (2.5%) and 12 times faster than the global average (1.4%) over the past two decades.
To put this into perspective, since 2000, no G20 country has achieved a decarbonisation rate of more than 11% in a single year - the highest level was achieved by the UK in 2014 (-10.9%).
The Index provides a stark illustration of the growing divergence between the global ambition to tackle climate change and the reality of current progress.
Our analysis shows that all nations need to work harder to reduce emissions to stand any chance of meeting the IPCC's 2030 deadline to reduce emissions by 43%, with a 78% reduction in carbon intensity now required in under seven years.
Emma Cox, Global Climate Leader, at PwC said:
“The fact the world needs to decarbonise seven times faster is a spur to action, not a counsel of despair. While the overall pace has to pick up rapidly, dramatic change is possible when business and policy makers align. The rapid acceleration of the deployment of wind and solar in several regions shows change can happen. The world is decoupling growth from carbon emissions, now we need that trend to become a surge.”
Now in its 15th year, PwC’s Net Zero Economy Index tracks economic growth and energy-related CO2 emissions data, against the rates required to achieve the aims of the Paris Agreement. It tracks how economies are progressing in breaking the link between economic growth and increases in energy-related carbon emissions.
More positively, our analysis shows that last year saw a surge in renewable energy adoption, which shows hope for an accelerated and market-led transition, with solar energy experiencing its highest growth ever recorded at 24.4% and wind energy increasing by 13.1%. The significant growth of renewables is primarily concentrated in Asia (particularly China), the USA, and Europe. This accelerated action needs to be echoed in wider economic sector transitions, infrastructure, and coupled with increased support to developing countries.
The Net Zero Economy Index also reveals that:
Dan Dowling, Net Zero & Sustainability Partner at PwC, said:
“The world's collective failure to get to grips with climate change leaves us on the cusp of an unpredictable and economically destructive time. We must now bend the curve on emissions growth and urgently seize the opportunity to realign our global economy and net zero pathway with a 1.5°C future climate.”
“To achieve our global ambition, and starting this year, it is time to embrace a bold, commercial and disruptive phase of global redevelopment that is driven by mass deployment of clean technologies, accelerated by practical innovation, and scaled with sustainable finance. The result of our choices now will be definitive for future generations who neither chose nor deserve a flawed inheritance.”
Notes to Editors:
The primary purpose of the Net Zero Economy Index is to calculate national and global carbon intensity (CO2 / GDP), and track the rate of change needed to limit warming to 1.5°C. To do this, we use the IPCC carbon budget to calculate how much emissions need to be reduced in the future, and divide this by the projected increase in GDP. This allows us to see the amount emissions must reduce to maintain projected GDP growth, providing insight to the scale of efforts required to decouple emissions from economic growth.
