Reactive N (Nr) releases are closely linked with greenhouse gas (GHG) emissions, and the simultaneous evaluation of them can help to develop overall effective mitigation options. In this study, we evaluated the characteristics of the Nr and GHG releases from staple food (rice, flour and corn-based fodder) production in China (2001-2010) and explored their mitigation potential. Results showed th...

In their recent article ‘Banning Trophy Hunting Will Exacerbate Biodiversity Loss’ [1], Di Minn et al. presented a set of arguments in support of trophy hunting. They suggested that trophy hunting will benefit biodiversity (i.e., the number of plant and animal species in an area) through several main mechanisms, including (i) increased funding for conservation; (ii) a smaller carbon footprint c...

The proliferation of online emission calculators and the growing popularity of carbon footprint assessments recently underscores an emerging interest among Americans in understanding their personal environmental impacts, especially in relation to greenhouse gas emissions. While studies have quantified carbon footprints at a variety of geographic scales using economic data, or a combination of e...

This article discusses the link between water conservation, reclamation, reuse and energy use as related to the goal of achieving the net zero carbon emission footprint in future sustainable cities. It defines sustainable ecocities and outlines quantitatively steps towards the reduction of energy use due to water and used water flows, management and limits in linear and closed loop water/stormw...

Wheat is one of the world's most favoured food sources, reaching millions of people on a daily basis. However, its production has climatic consequences. Fuel, inorganic fertilizers and pesticides used in wheat production emit greenhouse gases that can contribute negatively to climate change. It is unknown whether adopting alternative farming practices will increase crop yield while reducing car...

An efficient way for producing power, heat, and cooling while reducing CO2 emissions is through trigeneration. The emitted CO2 from trigeneration plant can be further reduced by producing biochar, which contributes negative carbon footprint to the system through sequestration of biomass carbon as char. This requires a gasification process to be added in the trigeneration system to produce bioch...

BACKGROUND The NHS has a target of cutting its carbon dioxide (CO2) emissions by 80% below 1990 levels by 2050. Travel comprises 17% of the NHS carbon footprint. This carbon footprint represents the total CO2 emissions caused directly or indirectly by the NHS. Patient journeys have previously been planned largely without regard to the environmental impact. The potential contribution of 'avoidab...
