Insights from leading experts into the main developments in British Standards, including PAS 2080 Carbon Management in Infrastructure as an industry game changer. Speakers with first-hand experience will highlight how this specification (PAS) is helping the sector address key challenges and opportunities for energy and carbon reduction. BSi will provide a briefing on PAS 2080 and other key standards, PAS 2050 on carbon footprint and PAS 2060 on carbon neutrality that can help organisations reduce carbon emissions and improve business practice to support sustainability goals.

• The Reality
• The Challenge
• Standards and Solutions

3. More frequent and extreme weather events

4. More extreme droughts

5. More frequent and extreme wildfires

6. Knock-on effects and feedback loops

7. Yet despite all this…

8. an IPCC special report on the impacts of global warming of
1.5 °C above pre-industrial levels and related global
greenhouse gas emission pathways, in the context of
strengthening the global response to the threat of climate
change, sustainable development, and efforts to eradicate
poverty
“Pathways limiting global warming to 1.5°C with no or
limited overshoot would require rapid and far-reaching
transitions in energy, land, urban and infrastructure
(including transport and buildings), and industrial systems.
These systems transitions are unprecedented in terms of
scale, but not necessarily in terms of speed, and imply deep
emissions reductions in all sectors, a wide portfolio of
mitigation options and a significant upscaling of
investments in those options “
[For] 1.5°C … renewables are projected to supply 70–85% of
electricity in 2050.

The Scale of the Challenge in the UK

10. • Sectoral Drivers on Carbon
“50% reduction in greenhouse gas emissions in the built
environment by 2025 against a 1990 baseline
An industry that has become dramatically more
sustainable through its efficient approach to delivering
low carbon assets more quickly and at a lower cost,
underpinned by strong, integrated supply chains and
productive long term relationships.”
…sustainable building industry is forecasted to grow at
an annual rate of 22.8% until 2017.”
Construction and Carbon

11. “….. the UK is driving forward the delivery of new
strategic infrastructure alongside the
maintenance, modernisation and renewal of
existing assets.. We must achieve this while
contributing to national reductions in carbon
emissions
The Government has no doubt that cutting
carbon is fundamentally important to long
term global economic, social and
environmental sustainability.
This report makes clear that reducing carbon
reduces costs. It is part and parcel of saving
materials, reducing energy demand and
delivering operational efficiencies.”
Infrastructure Carbon Review

12. • From the ICR
• 53% of UK emissions from infrastructure
• 1/3 of which we can control
• 2/3 we can influence
• CapCarb rising in relation to OpCarb
