SUSTAINABILITY, ADDRESSING OUR CHANGING ENVIRONMENTCO2 Emissions, A Review of the UK’s Domestic Target

Introduction

Climate change and global warming are unequivocally the biggest and most fundamental problems facing planet earth

d ki d t d Gl b l i d li t hand mankind today. Global warming and climate change are expected to have a cataclysmic effect across the globe. The

worst effects of climate change can be avoided if greenhouse gases incorporating carbon dioxide (CO ) in thegreenhouse gases incorporating carbon dioxide (CO2) in the

atmosphere are stabilised instead of being allowed to increase.

Introduction Cont.

The United Kingdom (UK) is striving to meet International, European Union (EU) and national targets of CO2 emission reduction through various strategies but mainly through thereduction through various strategies but mainly through the

Building Regulations – Part ‘L’ to satisfy the Energy Performance of Buildings Directive (EPBD) and the

Kyoto Protocol (KP)Kyoto Protocol (KP).

The UK is currently on Target to meet the commitments of the KP

The predictions indicated and by the UK’s Government own admission, the UK is currently NOT on target to achieve the domestic goal

The prediction of CO2 emissions by 2010 is currently 141.3MtC

The UK’s domestic goal is 130.8MtC by 2010

This equates to a shortfall of 10.5MtC and an overall CO2q

SUSTAINABILITY, ADDRESSING OUR CHANGING ENVIRONMENTCO2 Emissions, A Review of the UK’s Domestic Target

Discussion of Results Cont.

The current predicted shortfall of the UK domestic target is 10.5MtC. Buildings account for 48% emissions therefore 48% of the shortfall is attributed to the built environment The Builtthe shortfall is attributed to the built environment. The Built environment should therefore consider saving 5MtC/year to assist the UK to get back on track to meet the domestic target.

Conclusion

The UK will probably achieve Kyoto Protocol 12.5%p y y

The domestic target in not currently on schedule

One sustainable case study has showed 10tC/Year

500,000 building sustainable projects in the UK are required to bring th UK b k t k t t th D ti G lthe UK back on track to meet the Domestic Goal

By not doing anything your actually contributing to climate h ti itichange activities
