Climate Change
• Currently net energy uptake by earth causes heat energy storage and rising global temperatures
• 90% of this excess heat is stored in oceans
• 30% of CO2 absorbed by oceans

Conclusion: To achieve a 66% chance of limi:ng warming to 2°C, emissions need to be capped at 1,000 gigatons (measured from start of industrial age)

We had emiFed half of this already by 2011

Weather is changing
![Page 13: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/13.jpg)
Current rate of emissions are projected to cause rise 2.6 – 4.8 °C globally & sea level rise of 0.45-‐0.82m as oceans warm
![Page 14: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/14.jpg)
Despite slowdown due to natural factors, human ac:vity is influencing emissions and related rise in global temperatures;

Each of the last 3 decades has been successively hoHer than any other preceding decade since 1850

AR5: 95% certain we have been the dominant cause for warming since 1950s

Es:mates of buildings’ emissions as a percentage of total
“What percentage of CO2 emissions do you think buildings give rise to – directly and indirectly?“

The building sector must lead
![Page 26: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/26.jpg)

Mee:ng the Challenge
![Page 28: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/28.jpg)
2030 Challenge Impacts
![Page 29: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/29.jpg)
Aggressively implemen?ng building codes that meet the 2030 Challenge targets will drama?cally reduce CO2
emissions and transform the Building Sector into a central market sector for the solu?on to climate change.
![Page 30: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/30.jpg)
Reducing energy demand through building efficiency is significantly cheaper than producing the same amount of
energy by coal or nuclear power.
![Page 31: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/31.jpg)
Passive building pathway
Passive building achieves IPCC carbon reduc:on target of 80% below ‘90 levels
2030 Challenge targets: sustainable design, on-‐site RE and/or purchasing RE or RECs*
![Page 32: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/32.jpg)
“Let me put that into perspec:ve: 900 billion square feet is an area equal to 60 %
of the en:re building stock of the world.
That is how much we will build by 2030. We will essen:ally rebuild the world in the next two decades.
That is a huge opportunity if we do it right.” – Ed Mazria, Architecture 2030

The scale of the building energy challenge
![Page 34: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/34.jpg)
Building energy forecasts
![Page 35: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/35.jpg)
Energy efficiency contributed 63 exajoules (EJ) (1400 Mtoe) of avoided energy use in 2010 >> Larger than the supply of oil (43 EJ), electricity or natural gas (22 EJ each)
![Page 36: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/36.jpg)
Two thirds of the economic poten:al to improve energy efficiency remains untapped in the period to 2035
![Page 37: Passive Building, Carbon and Climate](https://reader034.fdocuments.in/reader034/viewer/2022052508/559c18d01a28ab27598b4603/html5/thumbnails/37.jpg)
Movement: Linking EE & CO2 reduc?ons
Clean Energy Campus Campaign • Campuses cer:fy their “beyond business as usual” GHG reduc:ons against these new methodologies by mee:ng specific performance benchmarks and other eligibility criteria. • Chevrolet pays campuses for these cer:fied reduc:ons and permanently re:res them to benefit the climate.
Campus Value: • Pilot projects say funding is strategic to realiza:on of GHG performances in LEED buildings and/or across their campuses. • Funding can contribute a 5-‐25% return on incremental capital needed to achieve leading-‐edge clean energy efficiency performance.

Carbon Crossroads

The Pathway to Two Degrees C
• We need to spend our carbon budget wisely of we are to meet the target
• If we fail to follow this path, we will exceed our budget between 2050 -‐ 2070

Poli:cal will.

We must make it!
