Climate change and the built environment: Key takeaways from COP26

In this recent BSI webinar, our sector expert, Keith Bryan, provided a high-level overview of the topic, summarizing the key outcomes from the 2021 summit and reviewing why climate change is such an important issue. Listen to the webinar to hear about some of the anticipated impacts of the agreements made during COP26, and why measuring and managing your carbon footprint is critical to business success.

While the webinar focused on the official outcomes of COP26, in this blog, we unpack some of the new alliances, agreements and initiatives, what they mean for the sector, and what comes next.

11th November 2021 saw the first Cities, Regions and Built Environment day at COP, after campaigners from The World Green Building Council and nine other international organizations stressed the importance of dedicating a full day to the sector. 

With the built environment accounting for almost 40 per cent of global energy and process-related emissions, global leaders highlighted the need for the sector’s diverse stakeholders to come together to drive change across policy, finance and industry. While the official COP26 talks and binding agreements are important, the tangible action to meet these agreements will come from the implementation. This will require a collaborative effort that includes both the public and private sectors.

From whole life carbon to net zero buildings - we’ve broken down some of the key outcomes and new alliances that came out of Built Environment day at COP26. 

COP26 saw more countries sign up to whole life carbon requirements as part of The World Green Building Council’s Net Zero Carbon Buildings Commitment.

The signatories have committed to the following by 2030:

• Reduce operational emissions of new and existing buildings and built assets
• Remove fossil fuels as fast as possible
• Power new developments and major renovations by renewables and achieve maximum reductions in embodied carbon 
• Compensate for any residual emissions where necessary
• Advocate for wider emission reductions through business activities
• Report on impact

This ‘reduction first’ approach targets both operational and embodied carbon emissions and signifies a step in the right direction for leading organizations to set out the blueprint for faster decarbonization. 

A total of 122 businesses, 28 cities and 6 states and regions have now signed up.

Alongside COP26, the UK Green Buildings Council launched their Net Zero Whole Life Carbon Roadmap for the Built Environment. Created in collaboration with over 100 organizations, the roadmap sets out recommended actions to achieve zero carbon in construction, operations and demolition.

The roadmap includes:

• A carbon footprint for the UK built environment
• A net zero carbon trajectory
• Information on how much emissions reductions need to be made in order to achieve net zero by 2050
• Policy recommendations
• Action plans for industry

The roadmap’s aim is to help operationalize this movement by translating concepts into actionable next steps for businesses and industry. 

On Cities, Regions and Built Environment Day, it was confirmed that 1,049 cities and local governments are now participating in Race to Zero, representing over 722 million people. Race to Zero is a global campaign to gather support and leadership from businesses, cities and investors in order to unlock sustainable growth and enable a zero carbon recovery.

109 regions, cities and states have also signed up to Race to Resilience, which puts people and nature first in a global ambition to build the resilience of 4 billion people by 2030. The campaign asks cities to pledge to transform urban slums, help smallholder farmers thrive and protect coastal homes and buildings against climate shocks.

One of the newest members is Maharashtra in India, where more than 124 million people live.

During COP26, 68 states, regional and city governments signed up to a range of cross-sector actions ahead of 2030 to decrease emissions, increase climate resilience and protect biodiversity as part of the Under 2 Coalition. This Coalition is formed of a global community of governments committed to climate action. Governments from the Under 2 Coalition, U.S. Climate Alliance and C40 acknowledged the need to focus on short term measures to maintain global temperature targets.

The Glasgow Breakthroughs are a series of government-led actions across key economic sectors that represent over 50 per cent of global emissions. This clean technology plan provides a framework for businesses and countries to accelerate clean technologies by 2030. 

At COP26, over 40 countries joined the breakthrough, agreeing to collaborate on standards and policies for clean growth across power, road transport, steel, hydrogen and agriculture. These countries included the UK, US and China. The goal for the built environment is for 100 per cent of projects (new and existing) to be net zero carbon across the whole life cycle by 2030. 

2030 Breakthrough ambitions for the built environment include:

• 20% of major construction companies, architects and engineers by revenue join Race to Zero 
• 20% of major real estate asset managers by AUM and investment companies by revenue join Race to Zero
• Cities representing 20% of the global urban population commit to significant actions to put new buildings on a pathway to net-zero by 2030 and all buildings by 2050, including embodied emissions
