Quantifying the Greenhouse Gas Emissions of Hazards: Incorporating Disaster Mitigation Strategies in Climate Action Plans
… can represent large peaks in a community’s greenhouse gas emission inventory. Components of the built environment destroyed by natural hazards have their useful life shortened, requiring replacement before functionally necessary. Though the hazard itself does not release greenhouse gasses, …

Determining Zambia’s potential for bioethanol production as a motor vehicle fuel to meet climate objectives by 2040.
… levels of emissions contribute to the global greenhouse gasses challenge. The greenhouse gasses are causing unpredictable weather patterns which have affected the agro business and general economic planning. This research looked at bioethanol as an alternative to gasoline in trying to mitigate …

A framework to assess the economic and uncertainty implications for technologies for use in decarbonization
The accumulation of greenhouse gasses is causing climate change on a global scale. From simulations of warming scenarios, it appears that complete replacements of fossil fuels within the global energy economy must occur within about 60 years if warming is to be limited to 2°C (Prinn et al., 2011). …

Carbon Sequestration in Tidal Salt Marshes and Mangrove Ecosystems
… due to the increase of the concentrations of greenhouse gasses implicated in global warming and climate change. Although coastal wetlands release the greenhouse gasses carbon dioxide, methane and nitrous oxide, these ecosystems maintain high performance in offsetting significant amounts of …

A review of the green economy in Cape Town: local policy in the light of international approaches
… climate change caused by the release of greenhouse gasses into the atmosphere. The green economy is an approach to economic activity that has been developed in an effort to mitigate against this and attempt to shift the world economy onto a more sustainable course. South Africa has a …

Detection and analysis of the causal relation between tourism and greenhouse gas emission: an empirical approach.
… is a threat to the inhabitants of our planet and greenhouse gas emissions have been identi ed as the main cause of this climate change. In order to reduce the e ects of climate change, we need to signi cantly reduce emissions of greenhouse gasses to the atmosphere. While the tourism industry …

Hyperbranched And Polydimethylsiloxane Based Membranes For CO2 Capture
… effective methods of isolating and capturing greenhouse gasses. Among the many methods currently being explored for CO2 separation, membranes have proven to be a promising solution. This thesis examines three types of possible membranes: composite layer membranes, hyperbranched membranes and …

Leakage of carbon dioxide from a simulated subseabed Carbon Capture and Storage reservoir: potential impacts on benthic biogeochemistry
… carbon dioxide emissions from the flue gasses of point source producers, such as power stations or cement works. The carbon dioxide is then stored in underground geological reservoirs so that it does not reach the atmosphere, reducing the rate at which greenhouse gasses accumulate and …

Examining the effects of policy interventions on increasing electric vehicle adoption in California
… significant effort to reduce global emissions of greenhouse gasses must address the growing concern of the transportation sector’s inability to meaningfully reduce its emissions contribution. A major shift in the primary fuel used in the sector away from petroleum-based fuel to electricity is one …

FUEL SWITCH TO BIOMASS FOR THE CONTINUED USE OF AN OTHERWISE STRANDED COAL FIRED STEAM ELECTRIC ASSET
… that are still being developed, such as Greenhouse Gases and the expense projected to install control equipment, may further reduce the plant's ability to compete in the generation market. It is likely that smaller, well maintained power plants may be required to discontinue operations …

Mechanics of proton exchange membranes : time, temperature, and hydration dependence of the stress-strain behavior of persulfonated polytetrafluorethylene
… as the world's supplies become more limited and greenhouse gasses become more of a concern. Proton Exchange Membrane Fuel Cells (PEMFC), in which protons from hydrogen gas are passed across a membrane to react with oxygen gas producing electricity, with water as the only waste product, are a …

Creating an effective and equitable legal carbon taxing regime for South Africa
… change is induced by the release of so called greenhouse gasses (GHG's) as a result of human activity, most notably by converting fossil fuels into energy. GHG's include Carbon dioxide (CO₂), Methane (CH₄), Nitrous oxide (N2O), Hydrofluorocarbons (HFCs), Perfluorocarbons (PFCs), and Sulphur …

Can the Kyoto Protocol to the United Nations Framework Convention on Climate Change achieve its ultimate objective?
… devastating effects of dangerous anthropogenic greenhouse gases caught in the atmosphere. A second major step towards legally binding commitments to reducing greenhouse gas emissions was made, after intensive negotiations, in Kyoto, Japan, with the signing of a Protocol to the Framework …
