每日英語跟讀 Ep.K204: You Can Live to Fight Climate Change
Climate change can seem like such an enormous problem that individual actions would have little impact. Consider Europe’s wide-ranging proposals this week to reduce its reliance on fossil fuels, including eliminating sales of new gas- and diesel-powered cars in the next 14 years.
But people can have an impact, experts say, both by how they spend their money and how they spend their time.
Mary Weathers Case, for instance, chose to offset the carbon cost of a cross-country plane trip for her family through the site Gold Standard. Case, a psychiatrist who lives in South Salem, New York, with her husband and two children, said she had been reading and watching more news about climate change during the pandemic and had been motivated to do her part after hearing about the searing temperatures in the West.
What surprised her, though, was that after spending $3,000 on plane tickets to Portland, Oregon, she could offset that carbon for $150.
“I was surprised that it was so cheap,” Case said.
Buying carbon offsets for a plane trip is one way to reduce your environmental impact. But people can allocate their money in other ways, both big and small, that reduce their contribution to climate change. Take how you invest.
With certain investments — namely, those that reduce or remove carbon from the atmosphere — there are defined ways to measure their environmental impact. With others, like water conservation, the metrics are not as clear because there is not an agreed-upon unit to measure.
“The improvement in measurement is growing by leaps and bounds,” said Sir Ronald Cohen, an early venture capitalist and the author of the book “Impact: Reshaping Capitalism to Drive Real Change.”
He advocates using what are called impact-weighted accounts, an initiative led by Harvard Business School, to evaluate a company’s positive and negative impact on the environment.
Yet he is also open to a less-bad approach. People invested in fossil fuel companies should consider that Exxon Mobil caused $39 billion in environmental damage from its carbon impact, according to Harvard Business School estimates, while BP caused $14 billion in damage. It is like deciding which energy bar is better for you to eat: Those that have less sugar have a better health impact.
Individuals can make other environmentally conscious choices as well, beyond carbon offsets or investing in cleaner energy.
除了碳補償或投資清潔能源以外，個人還可以做出其他有環保意識的選擇。Source article: https://udn.com/news/story/6904/5672865
