Carbon offsets: A controversial way to fight climate change

Image
At McGill, a university that boasts a large international student body and faculty, it is no surprise that many people rely on air travel to return for the start of the semester. Globally, the number of annual airline passengers in the past 15 years  has more than doubled , increasing from 1.9 billion in 2004 to 4.3 billion in 2018. Worryingly, the transportation sector, particularly the airline industry,  is the fastest-growing emitter of greenhouse gases  and, thus, a major contributor to climate change. As individuals and institutions seek to reduce their carbon footprint, many turn to purchasing carbon offsets, sold by independent companies such as  Carbon Offset Reserve  and  Plan Vivo . Carbon offsetting is a way of   counteracting  carbon emissions: By purchasing carbon offsets, parties provide funding for greenhouse gas reduction projects and activities.  Carbon offset projects  include renewable energy programs, methane c...

What is a carbon offset?

A carbon offset is a credit for greenhouse gas reductions achieved by one party that can be purchased and used to compensate (offset) the emissions of another party. Carbon offsets are typically measured in tonnes of  CO2 -equivalents (or  CO2 e) and are bought and sold through a number of international brokers, online retailers and trading platforms. For example, wind energy companies often sell carbon offsets. The wind energy company benefits because the carbon offsets it sells make such projects more economically viable. The buyers of the offsets benefit because they can claim that their purchase resulted in new non-polluting energy, which they can use to mitigate their own greenhouse gas emissions. The buyers may also save money as it may be less expensive for them to purchase offsets than to eliminate their own emissions. Many types of activities can generate carbon offsets. Renewable energy such as the wind farm example above, or installations of...

Water may be a immense issue and clearly deserves monumental attention. Not solely is there a risk of decline in water provides however there’s additionally a probable increase in demand. Like all resources, we've to manage offer and demand. meaning protective and managing water sources, managing demand and creating gains in potency. In Islamic Republic of Pakistan there's a larger decision to make massive dams to deal with water inadequacy and generate electricity. The matter with dams used for power generation is that in most cases they just displace water inadequacy from one place to a different. As a result of water inadequacy is such a vital issue, any construction should be preceded by a comprehensive impact assessment. additionally, Islamic Republic of Pakistan also can inspect alternative solutions – like star and wind. Pakistan’s across the country Determined Contribution (NDC) document submitted to UNFCCC, as a part o...
