Scientists Have United: Now’s the Time for the Building Industry to Do the Same

The latest IPCC Report, like every one that came before it, is an overwhelming call to action for civil society, governments, and industry if we are to urgently limit global heating and mitigate catastrophic climate change.
The Intergovernmental Panel on Climate Change’s 6th Assessment, Climate Change 2022 – Mitigation of Climate Change lays out what can and must be done based on what is necessary and what is physically possible. This is not based on historical trends because as the IPCC’s Co-chair Professor Jim Shea put very concisely at the launch press conference, “We are not talking about business as usual if we are going to address the problem of climate change.”
The report is extensive, clocking in at 3675 pages of the most up to date climate science and potential solutions, so we thoroughly recommend reading the Summary for Policymakers after reading this!
In this blog I’ve focused on two key takeaways from the report: that climate actions – those that can be embedded into architectural projects, all the way up to wider government policy – have extensively proven benefits for society, and that carbon emissions must peak by 2025.
Climate Justice
Tackling climate change is a matter of both climate and intergenerational justice: climate impacts are felt the most in parts of the world that contribute the least to climate breakdown and they will shape the futures of the young and every generation to follow them – with certain tipping points being irreversible. This latest report stresses the importance of justice in bringing about the transformative change that we need to see: “Equity and just transitions can enable deeper ambitions for accelerated mitigation. Applying just transition principles and implementing them through collective and participatory decision-making processes is an effective way of integrating equity principles into policies at all scales”. A key element of this report is the identification of co-benefits to adaptation and mitigation strategies – illustrated in the table below that identifies synergies and trade-offs between different actions and achieving the United Nation’s Sustainable Development Goals.
Energy Efficiency First
As we have been saying for years, getting all buildings more energy efficient is absolutely critical to achieving those goals and should be the first step in every sustainable design action plan. Steps like Passivhaus offer proven ways to achieve this. But for it to be a meaningful reduction we need every building that is being designed now to achieve this standard or better, if in three year’s time we are to have substantially reduced our operational emissions from new buildings.
