- There are lots of different ways organisations impact the environment
- Some ways to make a difference matter much more than others
- The best things make more than 1000x the difference of the least effective things
- The highest impacts are from global policy change and technological innovation
- Prioritise, prioritise, prioritise, and look after yourself
What makes a difference?
The environmental impact of all types of carrier bag is dominated by resource use and production stages.
Cotton bags should be reused at least 131 times to ensure that they have lower global warming potential than conventional carrier bags that are not reused.
Another popular movement is about people who are opting for reusable straws. But if we want to clean up the ocean, straws are far from the main driver. A study published in the journal Science found that plastic straws make up about 0.025% of all ocean waste, and another study found that 46% of the ocean waste was from discarded fishing equipment.
PrioritisationCorporate social responsibility is often more about marketing than it is about driving an impact. Virgin Atlantic offer 'sustainable' bamboo travel kits. I suspect bamboo toothbrushes are more harmful for the environment than plastic ones, and this draws attention away from the huge environmental impact of flying. This is greenwashing; when an organisation looks like they're doing something sustainable, but in fact it's papering over what matters.
David MacKay was a professor of physics at Cambridge, and head of the Department for Energy and Climate Change, wrote an excellent book called Sustainable Energy without the Hot Air.
If everyone does a little, we’ll achieve only a little. We must do a lot. What’s required are big changes in demand and in supply.He gave the example of a news article telling people to switch their mobile phones chargers off when not being used in order to reduce greenhouse gas emissions. He made the point that mobile phone chargers use less than 0.25% of a house's energy consumption. He made the full text of his book available here.
Choose 2-3 of these:
- Offsetting —I have no problem with offsetting at all, as if we can find good ways to stop carbon from entering the atmosphere, and fund those opportunities, then this is a net gain overall.
- Travel —encouraging staff to take the train rather than driving or flying is quick win, as trains create less than 10% the emissions of planes
- Supply Chain — this might be one of your biggest opportunities. It's worth asking suppliers about their life-cycle analysis and how their products are made.
- Office energy provider— you can get zero-carbon energy providers, e.g. Ovo, Bulb, Ecotricity, and this can be a really quick way to make a difference.
- Divestment of pensions and other financial investments
- Increasing vegetarian food options
Anyone can set a target
I've come across several organisations that have been under pressure around climate change and sustainability, and so they've set a target (e.g. reduce greenhouse gas by 20% by 2050) which is both unambitious, and often they've barely achieved any reduction at all. One telecoms provider only achieved a 1% saving in the last 5 years. So make sure that targets and metrics actually bite.
Global problems require global solutions
It's really important to consider the overall impact of each choice, and be open to surprising or systemic conclusions like providing more vegetarian options or advocating for industry-wide policies to lower emissions. These offer the opportunities to make the biggest difference of all.
I've compared the options I showed earlier on with how incredibly effective these charities are. Even a £10 donation per month is fairly small - and this has over 1,000x the impact of low-energy lightbulbs!
In 2019, the charity evaluator Founders Pledge came up with two recommendations for points of particularly high impact:
- The Coalition for Rainforest Nations - This nonprofit works on avoiding deforestation by partnering with governments and businesses.
- The Clean Air Task Force - This nonprofit works in the US and helps scale up zero-carbon energy systems, plus work on tightening federal and state environmental regulation
