Addressing Climate Change:
Individual and Global Solutions
Options to Reduce Individual Carbon Footprint
My carbon footprint amounts to 16.15 tons of CO2 annually-an amount it would take 550 trees to offset. (Conservation International, 1) In order to reduce this footprint, I am considering the following two tips: Clean your inbox
and Change your thermostat
.
My carbon footprint would be reduced by 0.7 tons(Conservation International, 1)keeping a clean inbox would reduce a ton of space for more. By moving all emails into one organized folder. One of the most important habits in maintaining a tidy inbox is to turn emails into actions on your to-do list. Let some messages pass by. Use rules to send the messages that you don't need to
right away into their own folders.Reduce the number of places where you manually file messages. Reduce the mental tax of filing by relying on search to locate messages.
My carbon footprint would be reduced by 0.06 metric tons saved annually.(Conservation International, 1) Turn the thermostat to 68 degrees while you’re at home, and drop that setting even lower when you leave for the day. Replacing your old thermostat with a programmable or Wi-Fi thermostat can make a big difference on your energy bills through the changing seasons. Your thermostat is directly involved with how much energy your HVAC system uses. Even when you think you’re using the correct settings, issues like placement and age affect how well the thermostat works and how much energy your HVAC system ends up using.
The strategy that would be best for me is Change my thermostat. Because this would save on energy and my light bill. This would also help by reducing the time it runs to keep the house adjusted to the outside. Policies to Reduce the Effects of Climate Change
Policy Set 1
This policy set will achieve the goal of limiting global temperature rise to 2 °C or lower over the next century. With the decrease in growth and the increase in transportation. If we reduce the land, food, and industry we should be below 2 °C by 2100. With the information that I have on my simulator it should be around 1.6 °C.(En-ROADS, 2) The drawbacks to the set of policies was transportation, building and industry. Because they have to be set as highly increases. I think
this is the only way to keep it below 2 °C. With the way the population going I do not think that this would occur as it is still growing. And they are coming out with electric automobiles. The possible benefits to the set of policies is to increase and decrease certain areas in order to balance. I think if the population increases then the transportation area will increase. Because people have to go work, school, and stores. Also, the carbon removal would increase tremendously.

Policy Set 2
The options is to increase energy supply, lower the population, reduce land, food, industry emissions, and increase carbon removal. These changes would help keep the global temperatures
to be lower over the next century. Each change had a drastic increase or decrease to remain low. The drawback would be a lower population. Natural gas would be high and along with carbon price. The possible benefits to be set carbon removal will increase afforestation while technologic will have a medium growth. The population growth will be low for this model. With these changes the information would be around 1.5 °C.
To achieve a reduction in temperature rise, Policy Set 2 would be most effective. Because conserving and restoring natural spaces and the biodiversity they contain, is important for limiting emissions and adapting to climate impacts. This can restore habitats and can remove carbon dioxide from the atmosphere. To address climate change will store carbon. This would help to reduce millions of deaths each year from air pollution and climate change. Having warming temperatures increases public health challenges like heat-aggravated illnesses. Conclusion
Because we can lessen the impacts of climate change by making choices that help advance solutions and reduce greenhouse gas emissions. These actions apply to both individual and global levels. With the decisions that we make can shape the world for decades or even centuries to come. If dealing decisively with climate change is important to ensure sustainable development, poverty eradication and for safeguarding economic growth. If we save energy at home and change the way we energize our homes. Using different transportation from gas to electric. Eating more vegetables and fruits and throwing away less food.

In this assignment, a back pressure cogeneration plant process (see Figure 1) producing district
heat (DH) and electricity will be designed based on given supply and return water
temperatures and DH production. Personal initial values are listed in Appendix 1, plant and
component efficiency assumptions and pressure drops are listed in Table 1. Using the given
and chosen values,
• determine pressure, temperature, specific enthalpy, and mass flow rate at each state point
• calculate net electric power, fuel consumption, and efficiencies for electricity and CHP
production
• draw the process in a T,s-diagram (boiler pressure drop is assumed to occur entirely in
superheaters)

In the Scientific American article on on the Carbon Wedge Framework, wedge #6 is Install CCS at 800 large coal-fired power plants.
Use the following assumptions for the question below.
Assumptions:
• P= 1000 MW (rated power of plant)
• CF = 65% (plant capacity factor)
. CSS Efficiency = 90% (90% of CO₂ emitted is captured and pumped underground)
Cco2 = 210 lbs CO₂/MMBtu (emissions per million BTU primary energy)
• e = 35% (power plant efficiency)
mc/mco2 = 12/44 = 0.27 (ratio of chemical molecular masses)
Calculation:
• Show with explicit calculations that CSS technology installed at 800 large power plants by the year 2050 could save 1 wedge of carbon
(1 billion metric tons of carbon/yr)
