Net Zero Targets: Considerations for Real Estate Corporates
As the end of 2020 approaches, many companies will see the expiration of their previously set sustainability targets. However, in the time period from when those goals were set to now, the sustainability community has increased its understanding of the ambition required for targets to meaningfully mitigate climate change. Previous goals that targeted arbitrary emissions reductions will no longer cut it as the world looks to prevent climate change’s worst effects.
In the real estate sector, 54companies have committed to reduce their emissions aligned with criteria set forth by the Science-Based Targets Initiative (SBTi). To limit warming to 1.5°C and prevent these worst effects, the IPCC has projected that total global emissions will have to reduce 45% by 2030 and ultimately reach net zero by approximately 2050 using a baseline year of 2010. While current SBTs represent a next step in limiting warming to this pathway, getting to net zero still looks like a black box to many in the corporate sector as methodologies undergo development.
What does “net zero” mean?
Before diving into the challenges and emerging guidance on how to reach net zero, companies should get clear on what net zero even means. The IPCC defines a net zero emissions scenario as one where remaining GHG emissions are balanced out by an equal amount of GHG removals. In other words, net zero entails companies reducing their generated emissions as much as possible and negating the remainder by funding carbon removal projects in clean energy, reforestation, and more.
Net Zero Guidance
Of the 5 main activities available to companies to reduce the climate impact of their operations, the SBTi notes those that focus on eliminating or removing emissions within a company’s own value chain as the best for long-term mitigation. Once GHGs have been emitted, significant controversy exists on what constitutes credible and sustainable removal. To put it briefly, carbon offsets have a place in the transition to a sustainable economy, but their effectiveness relies on the availability of new projects and only if they outpace the growth of new emissions sources. As finite resources on the way to a 1.5°C world, purchased carbon credits for projects outside a company’s direct control should only be considered once all options to decarbonize internally have been exhausted.
How to Achieve Decarbonization
For guidance on where to decarbonize internally, it helps to look at heavy hitters within the real estate value chain. Beyond implementing efficiency measures and sourcing clean energy to reduce the emissions from building operations, companies should also look to reduce emissions from their development activities. Embodied carbon emissions stemming from the materials used in construction projects represent a whopping 11% of global energy and process-related carbon emission and have also been called for disclosure by both GRESB and CDP.
Further emphasizing the importance of embodied carbon emissions, emerging net zero certification schemes have also required companies to address this emissions source. The International Living Future Institute’s (ILFI) Zero Carbon Certification requires companies to demonstrate at least a 10% reduction in embodied carbon before certifying a project as zero carbon. While the ILFI recommends the sourcing of local products as a proposed initiative, companies can also look towards recycled or alternative construction materials and focus on existing buildings rather than opting for new construction where possible.
While 2020 has been a benchmark year in more ways than one, companies should remember the need for ambitious emissions targets to reduce the worst effects of climate change. As organizations start to solidify the methodology behind a net zero target, companies should strategize as ambitiously as possible to avoid playing catch up once net zero becomes the new standard. As a next step, companies may check out the foundations recently published by the SBTi in developing a new corporate standard for net zero targets.
The rise of PropTech and its potential for commercial real estate
Investment in real estate technology has seen astonishing growth since 2012 as companies are seizing the digital landscape to create technological innovations that add value to property owners and occupiers. The term PropTech is primarily associated with start-up organisations offering a more convenient, digital platform to facilitate traditionally manual processes such as the purchasing of […]
Revamping Diversity & Inclusion During an Era of Racial Justice
Just as the COVID-19 pandemic has made us rethink health and wellness for our employees, tenants and buildings, so should the recent social unrest surrounding racism and police brutality help us to reflect on diversity and inclusion (D&I) efforts within our organizations as we make progress toward achieving our environmental, social and governance (ESG) goals. The growing consensus is that racial injustice makes sustainability impossible.
Scaling Building Resilience in the Face of Climate Change
In 2017 the U.S. experienced devastating storms, fires, and hurricanes that caused over $358 Billion in damages. And for countries and communities around the world, they continue to be impacted by climate change as weather patterns become unpredictable.
