Sustainability is the “capacity to endure.”

“sustainable development is development that meets the needs of the present without compromising the ability of

future generations to meet their own needs.” Brundtland Commission of the United Nations

“In 2050, around 9 billion people live well, and within the limits of the planet.”

Important Figures to Know

• 40% of Energy Used Globally is by Buildings

• 50% if Construction Industry included

• 60% of Global CO2 reductions until 2030 can be by Energy Efficiency (International Energy Agency (IEA))

• Local Carbon Economy– Build Competencies & Scale

• Global Technology Market £3.2Trillion


Page 12

Key Drivers


Key Statements and Programme

• 42% Reduction by 2020

• 80% Reduction by 2050

• “Reduce greenhouse gas emissions year on year, every year from 2010 to 2050” (1.11 CCDP)

• “Reduce energy use through both decreasing demand and increasing efficiency with which energy is used” (1.13 CCDP)

• Major Scottish Targets (CCDP 2.3):– A largely de-carbonised electricity generation sector by 2030– A largely de-carbonised heat sector by 2050 with significant

progress by 2030

Building Standards 2010: Other Key Changes in Section 6 - Energy• Minimum Services Efficiencies updated

• Biomass & Heat Pumps information added

• Solar Water Controls & Info Added

• Lighting efficiencies and requirements updated

• Minimum Comfort Cooling Efficiencies improved greatly– E.g Packaged air conditioners improved between 14-34%

• Maximum Specific Fan Power improved dramatically – E.g Central Mechanical ventilation improves by 28%– Maximum system pressure drops now stated

• Detail on requirements for Sub-metering added


Page 19

Decarbonisation of Electricity & Heat

• Focus on Reduction of Emissions from Building– Building Regulations (Year on Year improvements with Zero Carbon

Domestic 2016/2017 and Non-domestic 2019)

• Focus on Renewable Electricity– Wind– Biomass– Solar– Hydro– Wave/Tidal Power– Biomass CHP

Decarbonisation of Electricity & Heat

• Develop a “Commercially Viable” Heat Industry– Replace remaining natural gas networks with biogas and local heat

networks(2050)– 11% Renewable Heat by 2020– Off-grid properties utilising low carbon heat (2030)

Option 2: Zero carbon energy from wind turbine(s) (Bickershaw South) – supplying electric heating, electric hot water and electric cooling. Solar thermal hot water provides

zero carbon hot water to reduce output requirements of turbine(s).


Page 33

Option 4: Low carbon electricity and heat from a biomass CHP system (heat supplied by district heating system). Zero carbon electricity generation supplemented by grid supplied

electricity.

• Remit: To advise on, and aim to make early progress towards, achievement of the outcomes and targets of the Climate Change Delivery Plan.

• To identify relevant action and opportunities, and collaborate, to bring benefits to the Scottish economy .

• To identify where the Group can best target its resources and expertise to accelerate the development, investment and action required across the following areas: Heat, Electricity, Waste, Transport, Rural Land Use and Forestry, Consumer Behaviour and Attitudes

• To provide strong and visible leadership to Scotland’s business and non-governmental communities to inspire them to do more to reduce carbon emissions.

• To help drive innovation through partnerships and synergies between members

Page 39

• It was agreed that the best way to maximise efforts is to split up specific tasks to the following six sub-groups.– Public and Business Engagement– Transport - AECOM– Finance and funding – Land use and Forestry– Built Environment - AECOM– Opportunities and Challenges

Page 40

•2020 Action Plan

• Contains a range of actions and measures that will be progressed by the sub-groups

• The AP will be updated frequently and will be available on the website that is under development www.2020climategroup,org,uk

http://www.2020climategroup,org,uk/

Summary

• Business as Usual is not an Option!

• Tough Targets have been Set

• Opportunities Everywhere

• Rethink of Project Financing & Funding

• Getting the Right Team Early
