Did you follow the coverage of Cop26? I doubt you had time so here are the highlights to get you up to speed.
Before COP26, the world was on track for 2.7°C of warming, post COP26 this is estimated to have been reduced to 2.4°C, but only if countries deliver on their 2030 emissions targets. Not so many years ago, we were seriously contemplating temperature rises of 4°C or even 6°C as real possibilities so the needle has moved, but we’re definitely not out of the woods yet, and we need to speed up.
On a more pessimistic note the hope of keeping global warming below 1.5°C is disappearing is not already gone. To have a reasonable chance of limiting warming to 1.5°C by 2100, global emissions need to fall roughly in half by 2030, and reach zero by 2050. To put that into context humans emitted 5.4 per cent less CO2 during 2020, because of the covid-19 pandemic, but this year’s emissions were 4.9 per cent larger.
With respect to the built environment, 136 countries have now included buildings as part of their climate action plans (known as NDCs), up from 88 at the last major COP. Also the UK, Germany, Canada, India and the United Arab Emirates formed an initiative for developing low carbon steel and concrete and their stated goal is net-zero steel and concrete for public projects by 2050.
One of the most welcome announcements at COP26 was from the IFRS (International Financial Reporting Standards), which sets rules for public companies. They tabled a draft climate standard to measure the environmental efforts of companies. Hopefully this will mean that by 2023, it will be easier to compare and contract companies’ environmental performance, thereby identifying those best prepared for future challenges, and the ones that investors will be most interested in.
A lot of environmental activists watching COP26 criticised the pledges for being too vague and unsubstantiated but according to Christiana Figueres, a former executive secretary of the United Nations Framework Convention on Climate Change the tone of this COP differed to previous ones, with there being “much more urgency in the language, more alarm”.
Ultimately, UN climate summits alone can only do so much. The battle to keep global warming as low as possible will be won at ballot boxes, on the streets, in courts and in boardrooms. In the words of the young campaigner Greta Thunberg “Instead of looking for hope – start creating it.”
